improvement.

I would like to express my deepest sympathy for
those who suffered from the Great East Japan
Earthquake and wish the earliest recovery of theaffected area.
The year 2011 forced us to reaffirm theimportance of electrical energy for our daily living.
The momentum for energy saving is becomingstronger because of the Great East Japan
Earthquake and subsequent nuclear power plant
incidents.
As a developer and manufacturer of equipment
related to electricity, we believe that we cancontribute to energy saving for the entire society
through business activities by encouraging activities
to reduce environmental burdens generated fromour business activities as well as by developing andintroducing highly energy efficient products with
reduced electrical loss.

Management System
Legal Compliance and Others
We are keeping abreast of changes and revisions of the environmental laws and regulations which
we need to abide by in our environmental management activities monthly. If necessary to apply to us,
we inform it to all employees through our internal Environmental Committee,
Regarding othe requests, we input them in our computer system so that all the emploees and therelevants can refer to for their references every time in need.
We are reflecting all the laws, regulations, requirements and evaluation results in our internal rules,
regulations and standards and evaluating our legal compliance every year to make sure we do not
violate any laws, regulations or requirements.

Environmental Audit

Prevention of Accidents

We are conducting an environmental audit
every year to confirm our compliance with
ISO14001, implementation and performancestatus.
Our internal auditors form a team comprising of
those who have taken internal and external audit
trainings and deemed qualified to audit eachdepartment.
Currently, there are 28 internal environmental
auditors.
Each auditor reports audit results including
areas of improvement to each department
manager. Each department reviews theiractivities and engage in activities for continuous
improvement.
In FY 2010, 7 non-compliance cases wereobserved. Corrective actions were completed forall 7 cases.

We have developed a "Environment-related
Equipment Map" which shows where thoseenvironment-related equipments are in Head
Office and Tateyama Plant to prevent and detect
accidents caused by them abnormally.
If we determine that a certain equipment needs
more control, we check if the procedure set forthin the case of emergency are put in place, and if
the regular maintenance and measurement are
conducted. In this manner, we are well-prepared
to cope with an unexpected incident.
We have received no complaints from ourstakeholders about the environment-related
issues.
We have confirmed that all our measured
environmental data, including vibration and noiselevel, do not exceed legal and regulatory
maximum limits.
(Example) We are checking kerosene and oil
tanks every month to see if there is any cracks or
damages to prevent soil contamination.

Highlights of Our Environmental Activities
Establishing Eco Products: Environmentally Friendly Products and its Symbol
We have developed a new internal evaluation system on environmental burdens in order to provide
our customers with information on our products and our efforts to promote the development ofenvironmentally friendly products since 2010.
We are looking at the following 3 items in evaluating our products to reduce their environmental
burdens.
(1) Environmental burdens generated when our products are in operation at customers' site(2) Environmental burdens generated when our products are manufactured at our factories(3) Environmental burdens generated when materials and components we purchase are
manufactured.
Based on the above 3 items, we set our own criteria to certify and register products which satisfy
our criteria as "Eco Products." These Eco Products are highly efficient in reducing environmental
burdens. To promote Eco Products, we developed the following symbol which represent Eco
Products.

Cosel Co., Ltd. Eco Product Symbol

We will proactively expand our Eco Products to create an environmentally friendly low-carbon
recycling-oriented society and to continue to grow with our customers.
This symbol mark is used in our product catalogue issued in FY2011 on pages covering Eco
Products to provide information to our customers.

Highlights of Our Environmental Activities
Reducing Environmental Burden in Production Floor:
Limiting Chemical Use
We use isopropyl alcohol (IPA) as a diluent
for fluxes which are used in soldering our
products. We also use IPA for cleaning of
jigs and tools.
We were using about 20t of IPS per year
and discharging 9t of used IPA every year.
In FY2010, we reduced the use of thechemical by introducing an IPA regenerator
which regenerates used chemical andenables us to reuse the used chemical.
We were about to reduce the amount of
IPA we use by 4.3t per year.

Reducing Environmental Burden in Production Floor:
Reducing Power Consumption of Soldering Pots
30% of power consumption on the 1st floor of our
Tateyama Plant was attributable to soldering pots.
Based on the data on power consumption, we
realized that discharge heat from heaters which
preheat PCB was large. Therefore, we implemented
3 countermeasures to reduce power consumption.
(1) We installed insulator to the pre-heater areas toreduce opening.
(2) We modified the heaters from 3 heater types to 2
heater types.
(3) We started to turn off the pre-heaters during
lunch break .

Preheater of Soldering Pot After the CountermeasureThanks to these countermeasures, we were able
to reduce power consumption of the soldering pots
used for the production of unit type power supplies
by about 20%.
In FY2010, we implemented thesecountermeasures on 12 soldering pots within Cosel.
In FY2011, we are planning to implement the same
countermeasures to soldering pots in our suppliers.

Highlights of Our Environmental Activities
Participation in "Volunteer Meeting for Toyama no Moridukuri(Forest Improvement and Maintenance)"
Volunteer Meeting for Toyama no Moridukuri(Forest Improvement and Maintenance for Toyama
Prefecture) was held on Saturday, September 18,
2010 at Tateyama-cho Sogo Koen Park cosponsored by Toyama Prefecture and Support
Center for Toyama no Moridukuri.
The objectives of the meeting were to encourage
the citizens of the Toyama prefecture to participate
in forest maintenance and improvement,and topromote volunteer activities for forest improvement
and maintenance. The meeting was held as a
networking event for organizations which wereregistered with the Support Center for Toyama no
Moridukuri. A volunteer tour was also given to thecitizens of the prefecture where they had a firsthand experience in forest improvement activities.

Presentation of a Banner from the Governor

Many employees of Cosel and their families
participated in the meeting and sweated overchopping underbrush, cutting down bamboo trees
and clearing bamboo grass in the park.
Given the fact that bears are making
appearances recently, we cannot afford to ignore
forest devastation. However, maintaining a vast
area of forest requires both manpower and money.
It would be difficult for the local government to do italone.

Volunteers Cutting Down Trees

In this respect, cooperation from businesses isimportant. We would like to be involved in forest
maintenance and improvement of Toyama
prefecture in one way or another.
As one step to start our involvement, Cosel
registered as a corporation with Support Center for
Toyama no Moridukuri which was established by the
Toyama prefecture.
From FY2011 and forward, we would like toactively participate in events and training sessions
concerning forest improvement and maintenance.

Encouraging taking Eco Test: Developing People who Work on Environmental Issues
Eco Test (officially known as Certification Test forEnvironmental Specialists) is a certification test run by
the Tokyo Chamber of Commerce in order to develop
people with a wide range of knowledge who can play aleading role in tackling environmental issues and facilitate
the realization of a sustainable society where we canprotect environment
and achieve economic growth at the same time.
Cosel's employees started to take the test from the 6th
test and 31 of them have passed the test so far.
We are encouraging our employees to take the test by
subsidizing a test fee and making those who passed thetest eligible for certification reward monay.

"I decided to take the test because I thought as aworking adult it would be better to know about
environment. The scope of the test was wider than I
expected and it was hard to memorize a lot of
information, but I am glad that I passed the test."

Green Procurement

Supplier Management

At Cosel, we are facilitating "Green
Procurement" in which we procure
environmentally friendly components andmaterials in order to deliver environmentallyfriendly products to our customers.
We have defined "prohibited materials,""materials targeted for elimination" and"materials targeted for reduction" forcomponents and materials which comprise our
products. By doing this, we can prevent theentry of environmentally unfriendly chemicals
into our products.

We are evaluating the risk of use ofenvironmentally unfriendly chemicals by our
suppliers and ranking them at 3 levels.
This ranking is used for the "Measurement ofEnvironmentally Unfriendly Chemicals ofPurchased Materials" and "Audit of Suppliers'
Management of Environmentally Unfriendly
Chemicals." This ranking is reviewed once every
year.
Under this system, we audit and review how
environmentally unfriendly chemicals arecontrolled by high risk suppliers and how highrisk components and materials are controlled bysuppliers. We also facilitate registration of highrisk suppliers, materials and components.

Education on Environmentally
Unfriendly Chemicals
In FY2006, we conducted an educational
campaign on environmentally unfriendly chemicals.
Not only people working at our headquarters andTateyama Plant, but also people who are involved
with Cosel's products as our contractors and attransportation companies also participated in our
test and training sessions.
Using a training material developed by ourdepartment which is responsible for environmental
issues, training sessions were held by department
and tests were given to participants to check theirunderstanding about environmental issues. This
enabled them to deepen their understanding of theobjectives and the importance of managing
environmentally unfriendly chemicals as well asactivities taken by Cosel.

１３(*1)What is RoHS Directive?
RoHS Directive is an EU directive that will
restrict the use of certain hazardous materials
in electrical and electric equipment. The useof six substances, mercury (Hg), cadmium(Cd), lead (Pb), haxavalent chromium (Cr6+),
polybrominated biphenyls (PBB),
polybrominated diphenyl ethers (PBDE), will
be prohibited from July, 2006.
(*2) Excluding Maintenance Items(*3) What is REACH?
REACH is an regulation in which
manufacturers or importers of chemical
substances are obliged to register andevaluate chemical substances inmanufacturing or importing them and, in thecase of chemical substances of very highconcern, an authorization from relevant
authorities is required and high risk
substances are subject to limitation including
ban. REACH entered into force in June 2007.

Controlling Environmentally Unfriendly Chemicals
New Components, New Products and Mass Production Management
Since FY2006, we have been conducting fluorescence X-ray tests (*4) by target measurement area toprevent the entry of environmentally unfriendly chemicals into our products. The fluorescence X-ray test
allows us to confirm and verify whether or not a component is complying with our "Green Procurement
Standards."
The evaluation is performed at the following 3 levels.
We have four X-ray fluorescence instruments in total, two units at our headquarter plant and another two
at our Tateyama plant.
New Product Launch
In the past when we adopted a new component,
we conducted a "Quality Evaluation" to preventthe use of defective components. However, we
decided to conduct fluorescence X-ray tests formass production components to check thepresence of environmentally unfriendly
chemicals in newly adopted components. Test
results are compared to the data about
environmentally unfriendly chemicals which aresubmitted from suppliers before components are
officially registered.

Acceptance of Purchased Components
We also conduct fluorescence X-ray tests by target
measurement area when we accept purchased
components.

After Shipping Mass Production Products
After we ship mass production products, we evaluate
the presence of environmentally unfriendly chemicals
to make sure that Green Procurement Standards are
met on an ongoing basis, in addition to ourlongstanding electrical quality and mechanical quality
evaluations.

(*4)What is fluorescence X-ray test?
It is an analytical method in which
information on the existence of an atom isacquired based on the wavelength of a
specific X-ray and the intensity of the energyof the X-ray which is generated when X-ray isirradiated to an atom which comprisemolecules.

Fluorescence X-ray Instrument

Management of Production Lines
In order to prevent the entry of environmentally unfriendly chemicals into our products, RoHS-compliant
products and non-RoHS-compliant products are manufactured in separate lines on our production floor byusing separate equipment, jigs and tools.
Equipment, jigs and tools for soldering process are identified by signs and labels as shown in the following
pictures.

Environmental Conservation Activities
1．Energy Saving
87% of the energy Cosel consumes is electric power. Since the inception of the Company, all our
fluorescent lamps at our shop floors and offices have had pull switches to reduce the amount of
power consumed. We are making sure that lights are turned off during breaks and when not in use.
Furthermore, all the personal computers used at Cosel are set in the energy-saver mode and ourmonitors are automatically turned off when not in use. We are always taking small but importantmeasures.

●Cutting Down Power Consumption of Computers
Entire company has adopted a power-saving configuration inwhich a monitor goes off and a computer goes to a stand-bymode when it is not in use for a certain period of time.
Power switches are provided for each computer or for eacharea so that when somebody goes home, he or she can turnoff the power to reduce power consumption of computers not
in use.

2．Use of Renewable Energies
・In FY2004, 50kw solar power generator was installed at the rooftop of the Tateyama Plant
・In FY2006, 50kw solar power generator was added at the rooftop of the Tateyama Plant
・In FY2010, 50kw solar power generator was added at the rooftop of the Tateyama Plant
The impact of these generators is about 150,000kwh annually (CO2 emission of about 64tCO2 reduction).

3．Reduce● Reduction of Use of Air Cap Bags for Packing
Air cap bags were used when we shipped transformers
and sheet metals, etc. to contract manufacturers. Oncepackages were opened at contract manufacturers' site, theair cap bags were disposed of as industrial waste.
We reduced the use of air cap bags by changing our
packing methods using reusable Tupperware andcontainers.
Unpacking at contract manufacturers' site also became
more efficient.
(This is one example of our QC circuit activities)

Environmental Report2011 COSEL CO., LTD.

Environmental Conservation Activities●Elimination of Styrofoam
We had been using styrofoam as a buffer material for the shipment of our products because it
was cheap and excellent to protect our products. After being used, it had been discarded as theindustrial waste.
We have replaced plate-shaped styrofoam with cardboards and small styrofoam balls withbiodegradable resin in order to reduce industrial wastes.

4. Reuse●Reuse of Tape Reels and Semiconductor Sticks
We use chips to assemble power supplies. These
chips are shipped from manufacturers reeled up onto
plastic reels.
When chips are used up, the reels are left, whichused to be discarded as industrial waste of stabilized
type. Some semiconductors come in plastic sticks
when shipped from manufacturers. These sticks
had been discarded once semiconductors were used
up just like the reels.
Because they do not get deformed or worn afteruse, we have changed our procedures to reuse themby having manufacturers collect them after use.

5．Recycle●Paper Recycling
We are using both sides of copy paper sheets and, after bothsides are used, segregating them together with confidential
documents and magazines for collection and recycling byexternal organization.
Used paper collection boxes are placed at our workplace topromote paper recycling.

●Recycling of Waste Products andDefective products, unusable bottom
plates and dummy circuit boards thatwere cut off in production processes
had been discarded as industrial waste.
Now we are dividing these wastes
into metals and plastics, etc. before
disposing them so that they can beused as ingot and furnace combustion
improver.

Trend of Recycling and Reuse

Many types of wastes are generated in ourbusiness activities. Many of them arerecyclable, if we segregate them properly.
We at Cosel, Environmental Committee andBeautification and Recycling Committee areworking together in such activities as making
sure wastes are properly separated andemissions are reduced.

'10
（FY）

Chairman ofEnvironment Committee
Yutaka Tamou
Environmental Committee is focusing on (1)reduction of CO 2 emission and (2) improving recycle
ratio. In this fiscal year, the benefits of "modification ofsoldering machines to save energy" started to beseen, making a big contribution to power consumption
reduction.
As for improving recycle ration, we continued to
implement the countermeasures taken in the previous
financial year. However, due to the increase of our
production volume, the amount of industrial wastes ofstabilized type and controlled type increased and ourrecycle ration didn't improve. We will continue ourefforts to reduce wastes.

In FY2010, benefits of countermeasurestaken in FY2009 continued to be seen and theamount of domestic wastes didn't increase.
However, the amount of industrial wastes ofstabilized type and controlled type increased.
In FY2011, we will continue working with
Beautification and Recycling Committee toreduce the amount of industrial wastes ofstabilized type and controlled type.

As for our total energy use (crude oil equivalent)
as a business operator under the Law Concerning
the Rational Use of Energy was 1,321kl , which
was not subject to notification requirement .
However, it is expected that our energy use will
exceed the 1,500kl criteria within several years.
Therefore 2 employees took the Energy
Management Training in FY2010.
We have also confirmed that we are notspecified consigner as defined by Law
Concerning the Rational Use of Energy.

As we mentioned before, 82% of our CO2
emission comes from electrical power
consumption. In order to reduce this, ourEnvironmental Committee is playing a central
role in implementing many activitie.

3. Amount of Environmentally Unfriendly Chemicals
Among chemical substances handled by Cosel, Class I DesignatedChemical Substances whose handling amounts are subject to notification
requirement with PRTR are "lead and its compounds." However, leadsolder which falls under "lead and its compounds" is not subject to thenotification requirement because we have already changed all of our solder
to lead-free solder.

JEITA Toyama District Manufacturing ClassOn May 7, 2011 (Saturday), “4th JEITA Toyama District
Manufacturing Class" was held at Toyama Murata
Manufacturing Co., Ltd. 38 male and female students ingrades 5 and 6 from nearby 4 elementary schools
participated in the class and engaged in an electricalengineering project under the theme of "Let's create anelectric roulettes."
Cosel has been a part of this class since the 1st class. In
the 4th class too, our employees served as instructors andgave students guidance.
Students seemed to have struggled in unfamiliar tasks
such as assembling and soldering components. We
received suchcomments as "it looked difficult in the beginning, but once I
started, I was able to see progress and it became fun, " "I
was told that I was good at soldering and I was pleased tohear that," "I thought it was fun to make things."※What is JEITA?
Japan Electronics and Information Technology Industries Association.
An organization composed of manufacturers and sellers of such products as electrical and electronic equipment,
electronic devices, electronic components, electronic materials and software.

Cosel Cup Challenge Super Kids
This is our 23th anniversary since we became a
special sponsor for a sport event for boys and girlsof grades 4 through 6 hosted by a local TV station.
About 346 children in Toyama prefecture
participated in 5 events ranging from 100-meter
sprints, ball throwing, broad jump, zigzag dribblingand swimming.
It became a sparkling day as children competed,family and friends cheered for them.

Fund-raising Activities
Proceeds from the sales of our internal bazaar
and donation from our employees are donated to
Toyama Prefecture Cooperative Donation Society.
Donation amount is approximately 100,000 yen
per year, which is enough to buy a wheelchair forthe disabled or elderly.
The donation can be also applied to home-based
service, volunteer training, accident prevention
programs for children and fostering and nurturing ofyoung people.

In FY2008, we sent about100 spoiled postcards
to National Federation of UNESCO Associationsin Japan. The spoiled postcards are replaced withnew stamps and then sold. The proceeds of thesales of these new stamps is donated.
The donation is used for the World Terakoya
Movement, a program for people who had notbeen fortunate to have educational opportunities.
