Vol.78, No.4 Abstracts『Mpression Smart Motor Sensor』Lecture on predictive maintenance solution services
for Low-voltage three-phase cage induction motors
Shiro Ebara
Product Marketing Div. ALTIMA Company MACNICA
Predictive maintenance is the concept of predicting the failure or abnormality of equipment orequipment and performing efficient maintenance.
By introducing predictive maintenance, it is possible to detect the abnormality in advance and takemaintenance measures, thereby preventing sudden troubles.
In conventional preventive maintenance, which cannot detect sudden abnormalities.
Therefore, "condition based maintenance (CbM)" is attracting attention as a new method. By theevolution of sensors and analysis, it is possible to detect the condition of facilities and equipment andpredict failures and abnormalities.
"Smart Motor Sensor (SMS)" is a solution for predicting the failure of a three-phase induction cage
motor.
It collects data such as vibration and temperature and analyzes it in the cloud to determine thecondition of the motor.
SMS makes it easy to attach the sensor to the device, easy to set up, and uses a learning model for
automatic determination.
By eliminating the barriers of conventional CbM, it can accurately determine the abnormality ordeterioration of the motor.
In addition, SMS has the ability to determine the abnormality for each function of the motor and to
grasp the trend of the state transition and deterioration.
It provides the result to the user through a dashboard or smartphone application.
The API can also be used to link with other systems, enabling efficient management of multiple
equipment decisions on a single screen.
SMS is attracting attention as a new predictive maintenance method that replaces conventional
preventive maintenance.

NDT assessment of boiler pipe’s wall thinning using 3D scanner: current technology and future trajectory
Osamu Higashi
Anritsu Corporation
Boiler thinning is required by the Electricity Business Act to inspect the wall thickness by
ultrasonic flaw detection. It is a very labor-intensive task to illuminate each of the countless watertubes in a dark boiler to observe the subtle undulations of the thinning parts, and then apply anultrasonic probe to each of them one by one. The shape, arrangement, and thinning pattern of thewater tube are not uniform, and the numerical values by ultrasonic flaw detection vary dependingon the operator. There is an increasing demand for inspection technology that does not rely on
craftsmanship and does not overlook thinning areas due to fatigue.

Dye Q Technology is a technology development laboratory that solves the world's problems. By using
our proprietary technologies of "nano-bonding technology" and "reinforcement technology using newmaterials," it is possible to reinforce and extend the life of deteriorated concrete and steel parts. By
applying new materials and reinforcing them without replacing deteriorated ones, wasteful industrial
waste can be generated and significant cost reductions can be realized. In addition, it is widely used inboth the interior and exterior of the factory and the type of structure, such as application to lowtemperature and wet surfaces, and anti-corrosion paint that does not require keren. It already has a lotof achievements, and it has been expanded not only to the private sector but also to public works.

Traditional and State of the art cost reduction approach in abroad-- 5th generation automated paper testing machine
Hiromichi Yoda
Process Industry Division, ABB K.K.
Currently, industry got strong pressure from the market because Japan government announced
carbon neutral industry by 2050. In Japanese industry, especially material industry, there are several
serious potential issues like lack of human resource due to less attractiveness for young people,
retirement of baby boomer and the technical transfer. On the other hand, there are bright future in paperindustry because paper is excellent material for plastic reduction and new functional material, Cellulose
Nano Fiber.
ABB started following four approaches to cooperate with customer to solve facing issues.
1) Reliable and high performance online measurement for Refiner, Wet end control
2) Cutting-edge fiber analyzer for new material development3) Speedy, Safety and high precise paper testing machine
4) High speed, high precise and reliable automated paper testing machine
In the paper, 4) High speed, high precise and reliable automated paper testing machineis described. You
can understand how to utilize ABB 5th generation automated paper testing machine for mill operation
optimization.

The latest information of softness measurement by acoustic and stressKazumi Tanikawa
Sanyo Trading Co., LtdIn many cases, touch feeling evaluation is often performed by a panel test method in which the productstaff and inspectors evaluate and quantify the feeling when they actually touch the product. However,what one person finds to be nicer and softer may not feel the same to another. Texture is subjective andtends to vary by individual, gender, and nationality. In order to increase the objectivity of the evaluation,
it is desirable to use the equipment rather than the panelists.
Germany's emtec electronic company's TSA softness measurement device is a device that evaluates
the softness and texture of paper products such as tissue products. A measurement method thatsimulates the vibration and stress felt by human fingertips, and measures the three parameters that
affect the feel of the hand: true "softness", "smoothness/roughness", and "rigidity/flexibility". In addition,
the overall texture is evaluated as an HF value.

The study was conducted to evaluate the insect control performance of sunlight type LEDs， high color
rendering index (CRI) LEDs, white LEDs and prototype of LEDs in a comparative laboratory test. Musca
domestica (house flies) and Megaseria sclaris (scuttle flies) were used in the study. The number ofhouseflies captured by high CRI LEDs was significantly higher than that of white LEDs. The number ofhouse flies and scuttle flies captured by sunlight type LEDs was significantly higher than those captured
by white LEDs. The number of scuttle flies captured by sunlight type LEDs was significantly higher
than that of high CRI LEDs. The number of house flies captured by white LEDs was significantly higher
than that of prototype of LEDs. The results of this study show that high CRI LEDs and sunlight type
LEDs have higher insect attracting power than white LEDs. On the other hand, prototype of LEDs havelower attractiveness than white LEDs. These results suggest that insect attractiveness is not only
influenced by UV light but also by visible light.

Key Points for Manipulation of Several Data and Effective Measures Concerning with Pest Management
Takeo Ishizaki
Earth Environmental Service Co., Ltd
For the appropriate pest management, we have to consider both the effectiveness and the efficiency
because many factories have limited staff and time to spare for pest management. In this paper, somekey points for manipulation of several data and effective measures concerning with pest management
were mentioned.
At first we have to connect the monitoring data （investigation using trapping tools such as light trap）
with other data, for example the insect contamination data gained from the defect detector, which is very
important because these information indicates the direct contamination into the products. Also it isuseful to utilize the data for the cause of insect (e.g. wind direction and speed), which leads to thepreventive actions. In addition, in order to manipulate these data effectively, I recommend ‘analysis ofcorrelation’, which can verify the hypothesis for the insects’invasion.
As for the effective measures, we have to consider the characteristics of insects. Then it is useful for us
to think of pest management strategy that we construct the measures based on the insects’ invasionroutes ,which consists of the approach from the outside to the factories, the border of inside and outside,
the approach to the productive area in the factories, and the habitation of insects near the productivearea.
Finally, I introduce some specific measures such as traps, extermination, partitions, and so-called‘5S’. The important thing is that we need to select measures considering not only the merit, but also
the demerit or risk.

Report on the Results of the Fiscal 2023 Follow-up Survey on” JPA’s Carbon Neutrality Action Plan” andRelated Information on Measures against Global Warming in the Japanese Paper Industry
Yasuharu Sakina
Japan Paper Association
The Japan Paper Association (JPA) established its “Voluntary Action Plan on Environment” in 1997,
in response to The Japan Business Federation‘s call to the Japanese business community to organize“The Voluntary Action Plan on Environment”. Since then, JPA has carried out a follow-up survey andpublished the results every year.
As the Voluntary Action Plan finished in fiscal year (FY)2012, JPA newly started “the Action Plan
towards a Low Carbon Society” which is renamed “Carbon Neutrality Action Plan (Phase II)” this year
and has been actively addressing global warming prevention in order to achieve the following targets setin the plan:
Reduce energy derived CO2 emissions by 38％ by FY2030 from the FY2013 level .
As a source of CO2 absorption, increase total forest plantation area at home and abroad by
375,000 ha to 650,000 ha by FY2030 from the FY1990 level .
According to the results of FY 2023 follow-up survey (actual results for FY 2022), fossil-energy derived
CO2 emissions in FY 2022 was 14.33 million tons, which is 1.5 million tons lower than those in FY
2021(15. million tons) and is 4.5 million tons lower compared to those in FY 2013(18.83 million tons).
This is attributed to each manufacturer’s active efforts including energy saving and energy conversion
from fossil energy to non-fossil energy such as biomass energy.
In addition to the results of the follow-up survey, this report introduces the current energy situation in
the Japanese paper industry.

Plastic waste has become a reality as a major global risk to the environment due to a lack of disposal
facilities. Furthermore, CO2 continues to be generated throughout plastic production and plastic waste
processes, damaging the environment as a greenhouse gas. To address these environmental problems
from a standpoint of environmentally friendly materials, the concept of a biodegradable polymer
composite is proposed in this research. Cellulosic pulp fibers and polycaprolactone (PCL) are bothbiodegradable and can be applied to create a biodegradable plastic-pulp fiber composite. In addition, it
possesses excellent mechanical and structural properties depending on the design and manufacturing
technology. In this study, we applied traditional papermaking techniques and heat pressurization toproduce a PCL-cellulose composite with a high rate of degradation in soil and specific mechanicalproperties. Fourier transform infrared spectroscopy and scanning electron micrographs exhibited PCL
was retained among pulp fibers. The soil degradation test clarified the PCL-cellulose composite degradedfaster than plain pulp sheet since PCL is more biodegradable than cellulose.
