Title: Impeller of fluid coupling
Inventor: TOIDA SHIGERU
IPC: F16D33/20
Filed: 1981-10-16
Abstract: PURPOSE:To reduce the maximum stress of blade root sections, and to increase transmission force by disposing blades so as to generate bending stress generated by a working fluid and bending stress in the opposite direction in the impeller manufactured by arranging a large number of the blades to a core plate fixed to a shaft. CONSTITUTION:With the fluid coupling, a working chamber to which the working fluid is supplied is formed between an impeller connected to an input shaft and a runner impeller connected to an output shaft, and power from the input shaft is transmitted to the output shaft through said both impellers. The impeller 7 is formed by disposing a large number of the rectilinear blades 8 to the core plate 9 fixed to the input shaft 1. In this case, the rectilinear blades 8 are arranged so as to be displaced to a shaft core O so that bending stress generated by the working fluid and bending stress in the opposite direction are generated. Accordingly, bending stress generated by the working fluid and bending stress generated by the displacement of the rectilinear blades 8 are mutually denied, and the maximum stress generated in the root sections of the rectilinear blades 8  can be reduced.

Title: Battery capacity display device
Inventor: KAWAKAMI HIDEHIKO
IPC: G02F1/15
Filed: 1979-12-17
Abstract: PURPOSE:To make possible the displaying at less than supply voltage for one dry cell by providing an oscillation circuit which oscillates according to battery capacities, a display element driving circuit which is driven by the output of the oscillation circuit, a specific display element and an erasing circuit thereof. CONSTITUTION:When the voltage of a battery 11 drops down to, for example, <=1.2V, a multivibrator 17 is oscillated by a detecting transistor 16. This output is applied to the driving transistor array 18 of a display element 23. When at this time the signal 26 which remains high level during the coloring time TW is applied, transistors 20, 21 conduct and the current flows from the pole (a) in the display to a counter electrode (b), thereby causing an electrochromic display element (ECD) 23 to color. While there is no signal 26, the ECD 23 assumes an electrically isolated state and the coloring is maintained by its memory effect. If at this time the dry cell is exchanged, the circuit 17 does not operate and its output goes 0. The operator then presses an erasing button 25 to operate a monostable multi 24 which is turn causes transistors 19, 22 to conduct, thereby erasing the display of the ECD23.

Title: Flame-spraying method for end face electrode
Inventor: SHIBUYA MASATOSHI
IPC: H01G13/00
Filed: 1991-07-05
Abstract: PURPOSE:To equialize substantially the size of metal particles to be sprayed over the electrode pull out end face and obtain a metallic film capacitor whosse characteristic is stabilized with less variability of tan delta characteristic or with less degraded tan delta characteristic at a charging and discharging test by increasing the flame-sprayed amount of metal on the negative electrode side than the one on the positive electrode side. CONSTITUTION:In a flame-spraying method of an end face electrode for electrode pull out with regards to a metal capacitor, the feed speed upsilon- of a metal wire 10b on the negative electrode side is made faster than the feed speed upsilon+ of a metal wire 10a on the positive electrode side and the frame-sprayed amount of metal on the negative electrode side is increased than the one on the positive electrode side. Or the size phi- of the metal wire 10b on the negative electrode side is made larger than the size phi+ of the metal wire on the positive electrode side. This construction makes it possible to make the size of metal particles frame-sprayed from the positive electrode side at a lower melting metal temperature and the size of metal particles flame-sprayed from the negative electrode side at a higher melting temperature. It is, therefore, possible to make uniform the contact strength or the like between the end face electrode formed by the electrode pull out end face of a capacitor element assembly and the end face electrode formed by frame-spraying.
