Title: Position detecting device for moving body and origin position returning method
Inventor: OGISO TOSHIO
IPC: G05D3/12
Filed: 1988-05-02
Abstract: PURPOSE:To simplify the device and to facilitate a control procedure by enabling an area discrimination sensor to serve as an origin position detection sensor. CONSTITUTION:Whether a body 1 to be detected is in an R or L area about an origin position is detected from whether the output of the origin position detection sensor 6A is on or off at the position when the power source is turned on. When the body 1 to be detected is in the R area, the body 1 to be detected is moved in an L direction and put in the L area temporarily, and then moved in an R direction. When the sensor 6 detects the origin position, its driving is switched to low-speed driving and when an movement quantity detector (not shown in figure) detects a reference signal, the position is regarded as a real origin position and the body 1 to be detected is stopped. Further, when the body 1 to be detected is already in the L area, the body is moved in the R direction and when the output is inverted at the origin position, the driving is switched to the low-speed driving to detect the real origin position, thereby stopping the body 1 to be detected. Thus, an origin area is omitted to facilitate the control procedure and simplify the device.

Title: Power supply control circuit
Inventor: HARADA SHIGERU
IPC: G05F5/00
Filed: 1988-05-06
Abstract: PURPOSE:To prevent the occurrence of an oscillation state where the ON/OFF cycles are repeated by securing such a constitution where the power supply voltage is never set even though the battery output voltage is recovered after the power supply voltage is reset at consumption of the battery. CONSTITUTION:When the battery voltage VD drops and a reset signal R is produced from a voltage monitor circuit 8, a flip-flop 1 is reset and a power supply is turned off. Then the voltage VD is recovered. Even under such conditions, the extreme value of the difference voltage which is caused by the time difference between the rise of the voltage VD and the voltage rise of a prescribed time constant of a set input terminal does not exceed the base- emitter saturated voltage level at the base of a setting transistor Q1 of the flip-flop 1. Therefore, a power supply is not turned on again with recovery of the voltage VD in case the power supply is turned off due to the consumption of the battery. Thus it is possible to prevent an oscillation phenomenon where the power supply is repetitively turned on and off.
