Environmental Contribution through the Provision of Products (Eco-products)

We strive to develop environmentally friendly products by reviewing the environmental performance of new products based on our unique internal regulations (TES*). This is a framework where we set up a product development screening committee and conduct deliberations for each product planning theme in accordance with the new product development screening rules. The screening rules set forth the principles to be considered during development and design and stipulate that environmental measures should be examined along with compactness and minimization of the number of parts.

* Risk map

This map is created based on past internal and external cases of defects in order to prevent serious defects.

It is used to determine whether there are any potential risks in equipment design, manufacturing, and service provision and to take measures to eliminate identified risks.

* Development principles/design principles                             

We have “development principles” and “design principles” in place to ensure product design and development comply with requirements and to guarantee the safety of life, body, and property as well asenvironmental conservation.

Reviews, verifications, and viability checks are conducted in each design and development stage, with authority and responsibility clearly defined, and the results are strictly evaluated.

The Company recognizes its responsibility for the environmental impacts of its products over their entire life cycles. In 2016, the Technical Working Group of the CSR Committee unified the calculation standards for converting emissions to CO₂ at every stage from product manufacturing to disposal (life cycle assessment: LCA). The CO₂ emissions derived through this method are set as essential evaluation items in new product development screening. LCA targets are set at the time of design, and LCA performance is calculated and evaluated by evaluation organizations to determine the results. Since fiscal 2023, we have been carrying out Life Cycle Assessment (LCA) calculations in a sequential manner for existing products, simulating Scope 3 Category 11 emissions (CO₂ emissions associated with the use of products sold by our company), and evaluating emission reductions resulting from functional improvements. We will continue to make improvements to increase production efficiency and reduce emissions.

Life Cycle Assessment (LCA) compliance rate in fiscal 2025 design reviews (DRs)        

 LCA calculation compliance rate: 100% (3/3 reviews)

 LCA evaluation compliance rate: 100% (5/5 reviews)

Due to the nature of production equipment, the products of the Tokyo Seimitsu Group offer many hours of operation and have long service lives. Consequently, when converted into CO₂ emissions, power consumption from usage of these products accounts for a good deal of the total emissions over the life cycle.

This has prompted us to focus on developing and designing products to reduce the environmental impact during manufacturing activities conducted by our customers.

* Environmental impact caused by precision guaranteed over a wide temperature range：

Power semiconductors are key devices that control power converters. They are essential devices for the realization of a decarbonized society as they can reduce power consumption and use energy efficiently. Power semiconductors are used in various electronic devices including electric vehicles, railcars, refrigerators, air conditioners, wind power generation equipment, and renewable energy-related equipment.

The Group has strengthened its product lineup to support next-generation power semiconductors that can withstand high voltages and high currents, lose little energy, and be miniaturized.

Transmitting power efficiently to all parts of an automobile or aircraft, including the smallest ones, requires components that strictly conform to design and specifications. The ability to measure and manage the size, shape, roundness, and surface texture of components improves performance and fuel efficiency, helping to promote decarbonization.

Based on our basic philosophy of “No Measurement, no Manufacturing,” we are contributing to the improvement of performance and fuel efficiency in the automobile and aircraft industries through our measurement technologies.

In recent years, climate change brought about by greenhouse gas emissions has become increasingly apparent, and natural disasters have been occurring frequently around the world. In particular, internal combustion engine automobiles and coalfired thermal power generation are cited as generating large amounts of CO₂, and it is said that curbing these emissions is key to saving the global environment.

There is a call for rapid deployment of CO₂-free electric vehicles and solar power storage systems. Rechargeable batteries, including lithium-ion batteries, play a pivotal role in meeting this challenge. Our charge/discharge testing systems, which can inspect the charge/discharge performance and life of rechargeable batteries, are used for test batteries during development and inspect batteries during manufacturing, contributing to the development of safer, higher-performance batteries and confirmation of safety and performance in manufacturing.

The Tokyo Seimitsu Group is the only semiconductor manufacturing equipment manufacturer with “measurement technologies.” As new value creation unique to our company, we are developing semiconductor manufacturing equipment models with built-in measuring instruments. Equipped with Opt-scope, a 3D white light interferometer microscope that measures surface properties, the relevant model improves the detection accuracy of shape and surface properties, contributing to improved quality and productivity.

We have calculated how much waste and how much CO₂ emission we can reduce a year by adopting returnable packaging. Returnable packages are more durable than cardboard boxes. Collecting returnable packages from destinations and reusing the collected packages reduces waste and mitigates the environmental impact. An effort is underway to adopt returnable packaging for SURFCOM NEX.
