Latest Patents

Mitsuhashi's latest patents include an inkjet recording head and a method for manufacturing the same. This inkjet recording head features a two-dimensional array of pressure chambers, each paired with corresponding piezoelectric elements that apply pressure waves to the ink. The fabrication process involves temporarily bonding a piezoelectric plate onto a substrate, which is then subjected to sandblasting to create the piezoelectric elements. After bonding these elements onto a diaphragm that forms part of the pressure chambers, the substrate is removed. Additionally, dummy patterns are utilized to equalize the degree of side etching among the piezoelectric elements.

Another significant patent is the cross-connect optical switch. This device comprises an input array of optical input paths arranged in one direction and an output array of optical output paths arranged in a different direction. A switching region is formed between the input and output arrays, featuring a mirror array of optical reflection mirrors. These mirrors are driven electromagnetically and can be displaced between standby and operation positions. This innovative design allows for the switching operation between several hundreds of optical input paths and output paths.
