Title: Welding of electric welding joint
Inventor: ASANO HITOSHI
IPC: B29C65/30
Filed: 1994-03-15
Abstract: PURPOSE:To enable the axes of pipes composed of a thermoplastic resin to coincide with the axis of an electric welding joint connecting both pipes before welding the pipes. CONSTITUTION:When pipes 1 composed of a thermoplastic resin are welded and connected using an electric welding joint, wedges 5 are inserted in the gaps generated between the pipes 1 and the electric welding joint 2.

IPC: H01M4/36
Filed: 1993-02-10
Abstract: PURPOSE:To completely remove a surfactant, and prevent a liquid from being penetrated into a water repellent part even in a long time use by dipping a reaction layer starting material or a sheet reaction layer in a fluid solvent tank of ultrasonic irradiation to form a reaction sheet. CONSTITUTION:A reaction layer starting material or sheet reaction layer is formed by adding a surfactant to hydrophilic carbon black, water repellent carbon black, and ethylene polytetrafluoride followed by mixing and dispersing. The reaction layer starting material or sheet reaction layer is then dipped in a fluid solvent tank of ultrasonic irradiation to elute and remove the surfactant in the sheet, and a reaction layer sheet is formed. This reaction layer sheet is cut, and the support of a catalyst and heating are conducted to form a gas diffused electrode. Since the surfactant is never left on the ethylene polytetrafluoride, no tar is generated, no liquid is penetrated into the water repelling passage even in a long time use, the electrode is thus never deteriorated, and the life can be extended.
