Title: Steering device
Inventor: ICHIMURA KAZUHIRO
IPC: B62D5/09
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To easily recognize that a large collision energy acts on steering cylinders by reducing traveling performance of a traveling body in a case of operating a pressure of a prescribed value or more on the steering cylinder. SOLUTION: When left/right ununiform impact acts on steering cylinders 26, 27 and a pressure of a prescribed value or more acts thereon, a shuttle valve 29 is shifted by the pressure from bottom chambers 26a, 27a or rod chambers 26b, 27b of the steering cylinders 26, 27 and a pressure switch 30 is turned on. A first relay 32 and a second relay 33 are tuned on and a solenoid valve 37 is excited so that pressure oil discharged from an oil pressure source is fed to the bottom chambers of the cylinders. The output of an engine is reduced, oil quantity discharged from the oil pressure pump is reduced, and rotation speed of the oil pressure motor is reduced so that the traveling speed of the traveling body is reduced. This constitution allows a driver to recognize that some abnormality occurs in the steering without any change in outer appearance of the traveling body.

Filed: 1987-09-10
Abstract: PURPOSE:To change over the valve in the caption automatically to a normal position in case of failure by transmitting the pressing force of a push rod to a valve member via pressure in a pressure chamber being formed of a main piston and an auxiliary piston. CONSTITUTION:A main piston 5 is hollowed and an auxiliary piston 9 is fitted into the hollow part thereof, the both pistons forming a pressure chamber 11.

A push rod 15 which exerts a pressing force in accordance with the exciting current of an electromagnetic drive part 14 is allowed to contact with the auxiliary piston 9. In the case of an electric system failure, the electromagnetic drive part 14 is not excited and a spool 4 therefore is not changed over. Also the failure of a hydraulic system will not allow the spool 4 to move, since pressure is not produced in the pressure chamber 11.

IPC: G06F1/24
Filed: 1982-12-27
Abstract: PURPOSE:To prevent a breakdown of storage contents of an RAM by providing a transistor whose emitter and collector are connected to an address decoder side and the RAM side, respectively. CONSTITUTION:A transistor (TR) 20 is inserted between an address decoder 5 and an RAM11. The emitter of this TR20 and the collector are connected to an output end of the decoder 5 and a selecting signal input end of the RAM11, respectively.
