Title: Control valve in fluid pressure controller
Inventor: KOIKE ICHIRO
IPC: B60T15/36
Filed: 1993-03-25
Abstract: PURPOSE:To surely eliminate residual pressure at the time of non-operation after operation by providing a bypass fluid passage opening/closing valve which interrupts a bypass fluid passage when the inlet pressure is larger than the outlet pressure and communicates to the bypass fluid passage when the outlet pressure is larger than the inlet pressure. CONSTITUTION:When the pressure of an inlet chamber 21 is lowered, a valve piston 45 is operated to the left by a differential pressure between the pressure of a brake booster 5 and the pressure of the inlet chamber 21 and moved to the left limit position. By this, an air passage 43 is made to communicate to an air passage 44 through a valve cylinder chamber 40. Thus, even if a retaining opening/closing valve and a discharge opening/closing valve are both closed, air in the brake booster 5 is fully discharged outside through the air passage 43, the valve cylinder chamber 40, the air passage 44, a noise reduction chamber 33 and a discharge port 36. That is, no residual pressure remains in the brake booster 5.

Inventor: KASAHARA DAISHIRO
IPC: A62C3/02
Filed: 1991-03-29
Abstract: PURPOSE:To suppress the explosion or fire in an oil or gas well by forming a level by excavation after excavating the ground for a shaft or an inclined shaft to make a working place around a pipe and successively cutting and removing an outside pipe casing to expose the innermost casing pipe to cut off the level and providing an injection port to inject muddy water or seawater. CONSTITUTION:A level 13 is formed by excavation so as to continue to a shaft or inclined shaft 12 to be allowed to reach the outermost casing pipe 14 of an oil or gas well and the periphery of the level is further widely excavated to form a working place 15 and outside casing pipes are successively cut and removed by a cutter to expose the innermost casing pipe 16. A cutting-off device 17 is attached to the casing pipe 16 to cut off the oil, gas and water flowing through the pipe and muddy water or seawater is introduced into the pipe from an injection pipe under pressure to suppress the explosion or fire in the oil or gas well. By this constitution, the explosion or fire in the oil well can be suppressed without confronting to danger directly approaching the explosion or fire of the well and newly excavating a well.

Filed: 1995-03-27
Abstract: PURPOSE: To effectively suppress shift shock in the case of releasing lock-up regardless of causes of downshifting by judging whether or not the downshift is caused by rise in engine load and releasing the lock-up at slower speed in the case of judging NO than that in the case of judging YES. CONSTITUTION: A control unit reads respective kinds of signals in traveling of a vehicle and when a duty ratio of a control signal to a lock-up solenoid valve 51 is 100% and a downshift flag is 1, downshift is performed and at the same time the lock-up clutch 29 is disengaged. However, when the downshift is caused by abrupt increase in a throttle opening, the duty ratio of the control signal to the lock-up solenoid valve 51 is changed from 100% to 0%. This constitution can release lock-up quickly so as to prevent shift shock caused by lock-up delay in downshifting.
