Title: Hydraulic control device for power car
Inventor: IKEDA HIROSHI
IPC: B60K25/00
Filed: 1982-11-15
Abstract: PURPOSE:To improve the starting characteristic of a hydraulic elevator and to prevent failure of the hydraulic apparatus by controlling a by-pass oil path to be switched to a negative pressure sensor when the viscosity resistance of operation oil is larger than a setpoint. CONSTITUTION:When an engine is started to drive a hydraulic pump 3 in the condition that the viscosity resistance of operation oil is high, suction negative pressure in a suction pipe 13 becomes higher temporarily. Whereupon, a mover 17 of a negative pressure sensor 7 is moved to the left against a spring 21, so that movable contacts 19, 19 and the fixed contacts 20, 20 are brought into contact with each other to apply an electric current to a solenoid 14. Thus, a solenoid valve 11 is operated, so that the total quantity of operation oil fed out from the hydraulic pump 3 is again collected in a hydraulic tank 4 through a by-pass oil path 6. In this arrangement, operation oil having large viscosity resistance will not be fed to a hydraulic elevator, so as to remove such bad effects to damage the hydraulic pump 3.

IPC: G01R31/02
Filed: 1988-08-11
Abstract: PURPOSE:To make it possible to detect a heater disconnection in a phase control system by adding a comparator, current transformer, rectifier circuit and adder to a heater circuit. CONSTITUTION:After voltage conversion made by resistance R on one side, a current output I1 of a current output circuit 1 is inputted as the first comparison input A to a comparator 4. On the other hand, a current which flows to a heater 3 is drawn by a current transformer CT and converted into DC component by a rectifier circuit 5, and then amplified by an amplifier circuit 6, and then, increased by an adder 7, and then, this voltage is applied as the second comparison input B to a comparator 4. In this case, the addition is performed such that the potential of the second comparison input B is always higher than that of the first comparison input A. That is, the comparator 4 does not produce an output such that a potential of the second comparison input B always exceeds the potential of the first comparison input A, but when a state reverse to the above occurs, a detecting signal of heater disconnection is outputted. Thereby, it is possible to detect a heater disconnection in a phase control system.
