Title: Rotary shaft seal
Inventor: IWATA SETSUO
IPC: F16J15/3276
Filed: 1995-03-10
Abstract: PURPOSE: To provide a rotary seal excellent in a blister resisting property by setting the wall thickness dimension of a corner part of a first seal element unified with a corner part of a fitting like a cover from a refrigerant storage chamber side smaller than that of the other position. CONSTITUTION: A corner part 25 of a first seal element 7 is beveled with straight gradient to set the wall thickness dimension T thereof smaller than that of the other position. Thus, refrigerant once permeating in rubber of the first seal element 7 is diffused quickly when tending to expand (due to temperature rise and pressure variation) while being ejected to the outside-refrigerant chamber side. In the corner part of a fitting, an adhesive force of the first seal element 7 to the corner part 25 is small and cracks are liable to take place in the abrupt expansion of the refrigerant. However, by lessening particularly the wall thickness dimension of this portion, the generation and advance of the crack can be effective prevented, so that a rotary seal excellent in a blister resisting property can be provided.

Title: Ink jet printer
Inventor: KOIDE YOSHIO
IPC: B41J2/18
Filed: 1987-04-02
Abstract: PURPOSE:To prevent the formation of an ink ball which would obstruct a course of printing, by adhering an auxiliary plate or a wire to the back surface of a gutter. CONSTITUTION:Even though a gutter 16 and an auxiliary plate 20 are adhered to each other by an adhesive, they are not in perfectly close contact with each other on a microscopic basis, and minute gaps are left therebetween. The gaps serve as capillary tubes, whereby an ink stagnating at a lower part of the gutter is led to an upper part of the gutter (the back surface of a knife edge) through the capillary tubes by capillarity action, so that the back surface of the knife edge is constantly wetted by the ink. Therefore, ink droplets adhered to the knife edge are instantaneously absorbed by the ink wetting the back surface of the knife edge, and the ink is recovered together with the ink stagnating on the front surface of the gutter 16. Accordingly, an ink ball will not be formed on the knife edge.

Filed: 1978-06-30
Abstract: PURPOSE: To prevent the reduction of electrolyte on suppressing overcharge of a cell temperature of which rises by the use of the grid of Pb-Ca system alloy for the cell temperature of which rises and the one of Pb-Sb system alloy for other cells.  
     CONSTITUTION: When an engine 2 and cells S 1  to S 6  of the lead accumulator 1 are placed in a row, temperature of the electrolyte of cells S 1  to S 3  rises, especially the cell S 2  does higher since its radiating area is very narrow. Only for the cells S 1  to S 3  of the lead accumulator 1, which is loaded on a car, for example, the grid of Pb-Ca system alloy is used in place of Pb-Sb system alloy. By this way, an overcharge is suppressed even if temperature of the electrolyte rises, the reduction of electrolyte can be prevented on attaining the same extent value as other cells of lower temperature.

Title: Controlling method for preparation of paralleling generator off
Inventor: MORI NOBUYUKI
IPC: H02P9/04
Filed: 1986-04-08
Abstract: PURPOSE:To stably reduce a generator load by decreasing the output signal of a load limiter of a turbine controller to a minimum level in a preparation of paralleling the generator off. CONSTITUTION:When a load is reduced as a preparation of paralleling a generator off, a computer 1 outputs a load limiter (LL) drop command 3 to a LL 2 when a load is reduced to approx. 10% of a rated value. When an LL signal 5 decreases to become smaller than a pressure error signal 11, a steam control valve (CV) flow rate signal 10 from a low value priority circuit 4 is switched from the signal 11 to the LL signal 5, and the load starts reducing when the signal 5 reduces. A CV opening request signal 9 does not reduce the signal 5 by the small variation in a turbine speed due to the variation in a system frequency since a load set signal 8 is tracked at a level higher by 10% than the signal 10 in an automatic tracking mode.
