Filed: 1988-12-26
Abstract: PURPOSE:To ensurely perform metal melting to make possible repeated use by drilling a through hole in the bottom wall of a metal melting crucible made of ceramic used to mount on an electrically conductive base earthed. CONSTITUTION:A metal M is heated on the basis of electron beam irradiation (e) in vacuum on metal melting. The metal M melted by the electron beam irradiation (e) is allowed to flow in a through hole 1a in the bottom wall of a crucible 1, comes in contact with the upper part of an electrically conductive base 2 to cool so as to solidify as it is in contact with the base 2. The melting metal M of the crucible 1 is earthed through the metal M solidified in the trough hole 1a and the electrically conductive base 2 in contact with the solidified metal M and electrification of the meting metal M in the crucible is prevented thereby. Accordingly, the metal melting crucible 1 surely performs metal melting with the use thereof and a bumping phenomenon by over- electrification of the melting metal M is prevented. Since the crucible 1 is made of ceramic, it endures repeated use and difficult to wear without reaction with the melting metal M and the permeation of the melting metal M.

Title: Electric double-layer capacitor
Inventor: HARADA NOBUYUKI
IPC: H01G11/52
Filed: 1989-12-22
Abstract: PURPOSE:To make it possible to maintain the reliability of an electric double- layer capacitor by a method wherein a polarized electrode and a porous separator are adhered using halogenated polyolefin resin. CONSTITUTION:Polarized electrodes 11 and 11' are adhered to porous separators 13 and 14' using halogenated polyolefin resin 16. When the halogenaged polyolefin resin is used as the bonding agent for the polalized electrodes 11 and 11' and the porous separators 14 and 14', adhesion of these materials can be stably maintained for a long period of time, because the halogenated polyolefin resin is hardly dissolved not only by an aqueous electrolyte but also by organic electrolyte. Also, there is no increase in electric resistance by the dissolution of said bonding agent layer into the electrolyte. As a result, the deterioration in characteristics of an electric double-layer capacitor can be prevented even when it is retained in high temperature for a long period of time.
