Latest Patents
Niwa's latest patents include a process for producing solid electrolyte capacitors. This innovative capacitor comprises a capacitor element disposed in a case, with a rubber seal member tightly fitted in the upper opening of the case. Lead terminals project from the element and extend through the seal member. The fabrication process involves placing a TCNQ complex salt into a heating box, melting it, and then impregnating the capacitor element with the complex salt. After cooling in air to solidify the salt, the lead terminals are inserted through the seal member, and the case is constricted to seal off its opening, resulting in a solid electrolyte capacitor. Another patent details a solid electrolytic capacitor with an organic semiconductor, which includes a solid electrolyte layer formed by heating and melting TCNQ complex salt. This design reduces the influence of thermal stress during soldering, thereby suppressing the increase of leakage current.
