We measure toxic metals to the order of ppm using a Shimadzu EDX-720 (energy dispersive X-ray fluorescence spectrometer).
We respond to toxic substance regulations such as WEEE, RoHS and ELV, etc.

Patents/utility model rights

These are the "Electric part installation equipment for electrothermal material" and "Electric blanket" utility model certificates acquired at the time of founding of the company. The activities of the company started from these utility models.

This is the patent certificate for the "Seat-shaped heater and its manufacturing method".
This is the patent certificate for an "Apparatus to prevent the falling out of thread in a multihead needlework machine".
This is the patent certificate for an "Alarm apparatus on a needlework machine for sewing blemishes on covered or uncovered conductive wire".
 This is the US patent certificate for the same invention.
 This is the EU patent certificate for the same invention.
 We developed a terminal to connect different diameter electrical wires simply and with certainty. We opened a small window in the barrel section so that shielded wires can also be accommodated and designed the terminal so that solder would flow around with certainty when applied. (Obtained patent )
We also have many other patents and utility models, etc. under application.

Design/reliability

 This is a constant temperature/constant humidity built-in chamber. This creates an environment of -40 to +80°C and 10 to 95% rh, which we use in product design. Sized large enough to take one small bike, we are able to collect various types of test data.

 These instruments are for thermography to measure the state of temperature distribution. Apart from these, we use various instruments such as temperature recorders, etc., to develop highly reliable products.

 This is a "knee" endurance testing machine. The company's products are characterized by being "thin and flexible", but they are designed so that they also have strong endurance. This is a testing machine with a "knee-like" part attached to verify durability.
 We measure toxic metals to the order of ppm using a Shimadzu EDX-720 (energy dispersive X-ray fluorescence spectrometer). We are able to carry out safer product development by confirming safety at the design stage.

Equipment

 This is automatic wiring equipment. It is able to wire products with freedom using CAD/CAM data. A patented "Heater wire contact alarm device" is attached to the equipment, enabling us to prevent the outflow of defective products. Products can be wired freely up to a width of 1,100 mm.
 This is cutting equipment. It is able to cut products in complicated configurations.
 This is specialist turntable-type equipment. We also have a lot of other specialist equipment apart from this.
 We use equipment like this in order to insulate wire connections with certainty.

Inquiries
