Title: Gas generator for pressure vessel
Inventor: KURAMOTO SHINICHI
IPC: B05B7/24
Filed: 1988-07-29
Abstract: PURPOSE:To obtain a desired pressure even when a pressure vessel is preserved under high-temp. conditions by forming a water-soluble film bag contg. >=1 kind of reactant generating an inert gas by contact with >=1 kind of reactant with a water-soluble cellulose derivative. CONSTITUTION:The bag 3 contg. one reactant is made of a water-soluble cellulose derivative. Hydroxyethylcellulose, hydroxypropylcellulose, methylcellulose, carboxymethyl cellulose, etc., can be exemplified as the cellulose derivative, and those are commerically available. The powdery derivative, when used, is transiently dissolved in a solvent, and formed into a film by casting, etc. Since the watersoluble cellulose derivative bag 3 is thus used instead of a PVA bag, the bag is not insolubilized even when preserved in high-temp. environment for a long time, and hence a desired pressure can be obtained when the bag is placed in a pressure vessel.

Title: Electrolytic capacitor
Inventor: MINAMI SHINICHIRO
IPC: H01G9/02
Filed: 1989-07-24
Abstract: PURPOSE:To avoid hydration reaction of an Al electrode foil even if a large content of water is mixed for the purpose of reducing specific resistivity by a method wherein a capacitor element is impregnated with electrolyte obtained by dissolving at least one among boric acid, organic acid and their salts and crown ether in main solvent, i.e., ethylene glycol. CONSTITUTION:As crown ether captures protons in electrolyte with which a capacitor element is impregnated and shows the property of cation surface active agent, it is adsorbed by the surface of a cathode foil, and thereby hydration reaction of the cathode foil and generation of hydrogen gas are avoided. One of three types of crown ether, i.e., 15-crown-5 expressed by the formula (1), dicyclohexyl-18-crown-6 expressed by the formula (2) and benzo-18-crown-6 expressed by the formula (3) is employed. With this constitution, even if a large content of water is contained in an electrolytic capacitor, degradation of the reliability can be suppressed.

CONSTITUTION:The border parts of a conductive member 14 such as an expanded metal with numbers of space areas passing through in the direction of its thickness each are exposed on the surfaces of step parts 16 formed at the borders of four sides of a plate-like main member 12 made of woody fiber cement, and the conductive member 14 is placed between flat plate parts 12a, 12b, in sandwich shape. The conductive members 14 are brought into contact with each other through an elastically deformable conductive article 20 at the position where the members 14 are exposed on the step parts 16, and the panels 10 neighboring with each other are overlapped at the step parts 16 in shiplap shape and are fastened to each other with fastening means 22. After that, concrete is placed between the panels and is stuck together with the panels. In this way, since the conductive members 14 are electrically connected with each other at the whole field of the step parts, a large field to be not electrically connected can be prevented from occurring and thus a concrete structure can be shielded against electromagnetism by the use of the panel as a permanent form.
