Latest Patents
One of his latest patents is a contact structure of a lead. This invention allows for the easy formation of a contact structure that includes a lead and a bump made of suitable metals. The design ensures that the bump and the lead are soundly connected in terms of electricity and strength. The lead is formed by etching a conductive foil, while the bump is created through electric casting via plating. The bump connects to the lead's surface through a conductive connecting material, ensuring intimate contact with a holeless insulative sheet. The basal portion of the bump is forcibly pierced into the insulative sheet, providing a robust connection.
Another significant patent is the resistor array board. This invention allows for the easy insertion of protective resistors between circuit forming elements. Each protective resistor can be properly press-contacted to the circuit forming elements, and they can be easily replaced when broken. The resistor array board consists of a porous plate with multiple through-holes, where protective resistors are resiliently retained by electrically conductive spring elements.
