Latest Patents

One of Handa's latest patents involves a novel capacitor design. This capacitor features a hollow element created by winding a pair of flat electrodes with a separator in between. The design allows both ends of each electrode to protrude in opposite directions. An electrode connecting member is attached to the end surfaces of the electrodes using methods such as metal plasma-spraying, welding, soldering, and conductive adhesive adhesion. The capacitor is housed in a cylindrical metal case that contains a driving electrolyte and is sealed with a plate. This design reduces the resistance of the electrodes, enabling a smaller size and fewer components.

Another significant patent by Handa is related to a piezoresistance paste and a mechanical sensor utilizing this paste. The mechanical sensor is designed for high sensitivity and reliability. It consists of an insulating substrate with a pair of electrodes and a piezoresistance element connecting them. The element is primarily made from a specific glass composition and includes ruthenium oxide powder. The piezoresistance element is formed by coating and baking a paste that contains these materials.
