Wasabo Hydropower Plant of Kamioka Mining Completed
Operation Started - May 15, 2015
Mesco’s Domestic Marketing & Sales Dept., jointlywith our Kamioka Branch, received an order from
Kamioka Mining Co., Ltd. for construction of Wasabo
Hydro-Electric Power Plant, and started its
operation on May 15, 2015. The project took about
one year to be completed, while the project team had
to struggle with an unusually heavy snowfall of arecord level that hit the construction site in thewinter time. Kamioka Mining Co., Ltd. has focused
its efforts on development of renewable energy
sources, and this newly built power plant is an
example of those activities. It produces a maximum
output of 840 kW and has been running successfully.
We also received an order for Mesco Pipe to be used
for the pressure water pipe line that runs from thewater intake to the turbine. For high pressure
applications, our Aramid sheathed polyethylene pipeof the operating pressure of 2.0 MPa as well as highdensity polyethylene pipe products are used.

We are committed to delivering engineeringservices that contribute to our customers’ needs on
a continued basis, by putting together Mesco’s
technological resources and expertise.

On March 31, 2015, Kamioka Branch completed theultra-high vacuum duct installation and electrical workfor KAGRA, and handed over the project to Institute for
Cosmic Ray Research, University of Tokyo. This project
involved the work of carrying in ultra-high pressure
vacuum ducts of the respective diameters of 800 mm and1,000 mm and of a combined total length of 6 km, into
straight tunnels of 3 km each in length that run on
squarely crossing X and Y-axes, and installing them inplace. The extremely stringent aligning accuracy
required for the installation work was achieved over theentire duct length of 6 km, and thus the vacuum
pressure of 10-7 Pa was achieved. We also carried out
such other tasks as carrying in and installing a variety ofvacuum vessels. A huge vacuum vessel weighing 11 tons,
called “Cryostat”, in particular, attracted attention, andits handling and installation process was televised by

NHK. This facility is intended for detection ofgravitational waves involved in Albert Einstein’s
famous “General Theory of Relativity”. Successfuldetection of gravitational waves is hoped to lead towinning a Novel prize. Mesco also contributed earlier tothe construction of “Super Kamiokande”, anotherresearch facility of Institute for Cosmic Ray Research,
University of Tokyo, and “KamLAND”, a researchfacility of Tohoku University, as well. It is indeed apleasure and an honor for Mesco to be playing animportant roll in such advanced technologies associatedwith cosmic ray research programs.
Mesco is committed to delivering products of the quality
and at the cost that meet our customers’ needs bymaking the best of our technologies backed by ourexperience and references.

PT. Mitui Kinzoku ACT Indonesia Plant Completed
Mesco completed a turn-kry plant engineering,procurement, and construction project for PT. Mitsui
Kinzoku ACT Indonesia and handed it over on March 9,
2015. This was our second plant construction project
carried out in Indonesia, following PT. Mitsui Kinzoku
Catalysts Jakarta’s project. We successfully delivered
the plant on schedule despite the harsh conditions
typical to Indonesia we had to face, such as the lawsystems changing day to day, quality of the soil whicheasily gets inflated with water, and a long lasting rainyseason, with which we were proudly credited by thecustomer. Mesco will continue to contribute to ourcustomers’ needs in their entering overseas operations
and their expansions, by providing services which suit
the respective local legal systems.

Completion Ceremony

Delivery of ISA Stripping Machine to Pan Pacific Copper
Production Increase of 30,000 t/y Enabledat Tamano Smelter
Mesco delivered an ISA process permanent cathode (PC)stripping machine for the No.1 copper electrolysis plant ofHibi Smelter and handed it over. This was the second unitthat followed the stripping machine delivered earlier to theNo.2 copper electrolysis tank house in 2006. Hibi Smelter is
now operating 100% on the PC process. While the electrolytic
copper is produced mainly in two different processes, i.e., the“Starting Sheet Electrolytic Process” and the “PC Process”,
the “PC Process” has now virtually become the standard
electrolytic copper process used in many countries in theworld, thanks to its feature that it does not require starting
sheets to be produced, thus improving the productivity
significantly.

PC Process Now Employed for Entire GroupThe PC process is used by Pan Pacific Copper, Ltd. not only
at its Hibi Smelter, but also at its Hitachi Copper Refinery
where the PC process was first introduced in Japan and also
at its Saganoseki Smelter. Mesco thus continues tocontribute to improvement of our customers’ productivity by
fully utilizing our technological expertise of high level
accumulated in the non-ferrous metal smelting operations.

2015 NEW Environmental Exhibition BoothStraight 5-Year Booth Exhibition
Mesco has set up a booth consecutively for five years since2011 at the Environmental Exhibition. The exhibition thisyear was open for four days from May 26 through May 29.
The number of visitors to the exhibition totalled 167,540,
many of whom also paid a visit to Mesco’s booth. Exhibitedat our booth were display models of the Wasabo power
plant generating a power of 840 kW and the latest boiler
dust removal equipment, as well as panels showing ourindustrial automatic machines and so on. We received agreat amount of responses from those who kindly visited
our booth. We sincerely appreciate the attention paid to ourexhibits and cordially thank every one of those who sharedtime with us at the show.
We will continue to strive to propose the best of our offers,
by keeping in mind one of Mesco’s mission statements“Putting Our Customers First”.

Thanks Again
for Visiting Us !!!

Finally
In this issue, we took up as the main topic theWasabo power plant delivered to Kamioka Mining
Co., Ltd. As presented above, we attractedattention from a large number of visitors at theEnvironmental Exhibition. We will also be
providing full support to Mitsui Mining & Smelting
for its large-scale hydro-electric power plantrenewal project. Hydro-electric power plants havean advantage of a long life of 40-50 years. Use ofMesco Pipe should further contribute to achieving
longer life of the systems including the conduits.

Among many other renewable energy sources, thehydro-electric power generation, assisted by proper
planning of the conduit routing in lessenvironmentallydestructivemanners,
isconsidered to be a more eco-friendly energy source.
We will, by joining our forces together, continue tostrive to contribute to forming a moreenvironmentally friendly energy society. As such,
we would appreciate your continued support andattention.
