Title: Battery
Inventor: YOSHINO MASAAKI
IPC: H01M2/16
Filed: 1990-10-25
Abstract: PURPOSE:To prevent steam and carbon dioxide in the atmosphere from infiltrating into a battery over a long period by interposing a fluoropolyimide film as an oxygen selective permeation film between an air intake side of a gas diffusion electrode and an internal surface of a battery vessel. CONSTITUTION:A compound film 11 is interposed between a porous film 2 and a porous unit 4 for diffusing oxygen and arranged so that a side of a fluoropolyimide film is opposed to a side of an air intake hole 3. In a high load test, intake of water and influences of evaporation and carbon dioxide are decreased with a short discharge period, but in the case of low load discharge, the discharge period is increased, further in the case of the outside air in high or low humidity, the compound film is regarded as important in order to obtain battery characteristic excellent in preventing transmission of water and carbon dioxide rather than a supply speed of oxygen. Thus by using the compound film 11 provided with the fluoropolyimide film on the porous unit 4, the excellent characteristic of preventing permeation of water and carbon dioxide in the atmosphere is obtained, and liquid leakage resistance can be provided.

Filed: 1993-10-26
Abstract: PURPOSE:To obtain structure and method for monitoring the film thickness effectively by smoothing a significant level difference at a monitoring part thereby eliminating the unetched part in the metal wiring. CONSTITUTION:At a monitoring part defined in a semiconductor device, a field insulation film 2 and an interlayer insulation film 3 are patterned on a semiconductor substrate 1.

IPC: B25J19/00
Filed: 1990-10-25
Abstract: PURPOSE:To prevent a core wire from disconnecting with a cable being strongly bent, by holding the cable with its spreading so as to surround the circular arcuate part of a spreading member thereon.
