Title: Electrolyte for driving electrolytic capacitor
Inventor: YAMADA HIDEMI
IPC: H01G9/035
Filed: 1989-09-25
Abstract: PURPOSE:To provide excellent compounding to an electrode foil, to reduce a leakage current, and to obtain an electrolytic capacitor having a long life by employing trimethoxybenzoic acid or its salt as its additive. CONSTITUTION:Trimethoxybenzoic acid or its salt is added to electrolyte for driving an electrolytic capacitor formed of organic polarizable solvent, carboxylic acid or its salt. The trimethoxybenzoic acid includes, for example, one or more types of 2,3,4-trimethoxybenzoic acid, 2,4,5-trimethoxybenzoic acid, 3,4,5-trimethoxybenzoic acid.

Title: Insulating spacer
Inventor: YAMAGUCHI KOICHI
IPC: H02B13/02
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To ensure the secure contact of a movable contact to a fixed contact at the disconnector of a gas insulated switchgear by separating the interface between the inner surface of a metal ring a and a resin forming layer by the constriction in forming the resin forming layer, and tightly contacting the resin forming layer, whose interface is separated, and the outer surface of a pin. SOLUTION: For example, a metal ring 1 and a charging-part-conductor bonding metal fitting 2 are set in a split-ring metal mold, which is closed from the direction, and the mold is closed and arranged in the longitudinal direction. After air is drawn out from an resin injecting port on the metal mold, filler- adding-liquid shape resin is injected, and the resin is hardened by the heating of the metal mold. In this case, the contraction of the resin part of a width (d) is larger than the contraction of the width of a pin 12. Therefore, compressing stress (p) is generated at the side surface of the pin 12, and the part between the resin forming layer 3 and the pin 12 is brought into tight contact. Therefore, the fixing of the resin forming layer 3 to the metal ring 1 is ensured regardless of the presence of the gap between the metal ring 1 and the resin forming layer 3.

The material is then subjected to the current conduction treatment so that the peak current density attains 0.25-1.20A/dm<2> total current density or 0.14-0.70A/dm<2> negative current density. The current density is thereafter forcibly dropped at least once so as to be made about 10-95% of the current density at the point of this time. These treatments are executed in the same bath. The stability of the color tones and throwing power are improved by the above-mentioned method.

Abstract: PURPOSE:To binarize added/averaged picture signals with threshold, by adding/ averaging picture signals of plural pictures of a scanning type electron microscope, detecting the maximum value and the minimum value of picture signals, and determining threshold based on the average value of these two values. CONSTITUTION:An S/N-improved signal is got by processing picture signals of plural pictures of a scanning type electron microscope through an addition circuit 3, a memory 4, and a division circuit 5. On the other hand, the maximum value and the minimum value of the picture signals are detected through a maximum value detecting circuit 6 and a minimum value detecting circuit 7, and processed through memories 8, 9 and average value extraction circuits 10, 11.
