micro chemical chip made with mass production technology jointly developed by Panasonic and Micro Chemical Giken.

Panasonic and Micro Chemical Giken (Saiwai-ku, Kawasaki City), a venture company from the University of Tokyo, announced on April 6 that they have developed a technology to mass produce micro chemical chips, which can be used to create a single chip for analytical equipment used in blood tests, pharmaceuticals, and environmental research. The glass molding method used for the production of aspheric lenses for cameras, etc., which was owned by Panasonic, was converted to the new method. With the newly developed technology, it is possible to produce chips with a diameter of up to 50 mm and mass produce tens of thousands of chips per month. The low cost also has the advantage that the chips can be disposable on site. Currently, the mainstream chip material is resin, which is easy to mass-produce and low-cost. However, resin is difficult to resist chemicals and the environment, and this has been an issue for its further spread.

Testing a motor that does not use a permanent magnet.

Rizik and Taiyo Denki Engineering (Saiwai-ku, Kawasaki City) will jointly develop an electric two-wheeler equipped with a motor that does not use permanent magnets, with the aim of developing a prototype in July. Based on the results of the experiment, the company will make improvements and appeal the effectiveness of motors that do not use permanent magnets to the two-wheeled vehicle market. The system, which is based on Rizik's technology, regenerates the power generation energy stored in the coil to the power source when the current exceeds the set value in the power generation operation, and returns to the power generation operation when the coil current drops due to the regeneration operation to repeatedly maintain the power generation and regeneration operations. The company will supply the control unit, and Taiyo Denki Engineering will incorporate it into the motor and install it in the motorcycle.
