Latest Patents

1. **Electrolytic Double-layer Capacitor**: This invention features an electric double-layer capacitor, which includes a gasket encircling a pair of polarizable electrodes on opposite sides of a separator. It incorporates a pair of collectors on the outer sides of the electrodes, which are sealed to the gasket. The gasket is ingeniously crafted from a base of vulcanized rubber, complemented by resin layers obtained through fusion-welding polyolefin resin. The collectors are heat-sealed to the gasket, ensuring a reliable and efficient design.

2. **Tubular Ceramic Capacitor**: In this innovative design, the tubular ceramic capacitor utilizes a lead terminal made of Dumet wire for connecting to an internal electrode. The internal and external electrodes are plated on both surfaces of a tubular ceramic dielectric, except for the end faces. This configuration allows the lead terminal to be soldered securely within the inner bore of the dielectric, reducing the amount of solder needed and effectively preventing the internal electrode from peeling off.
