Abstract: PURPOSE:To prevent heat generation at the time of energization by controlling the output current of an energizing control circuit for supplying power to a driving means according to the on and off periods of a switching means. CONSTITUTION:A controller 1 receives the output of a linear sensor 20 and detects the present speed of a card carrier base, the speed signals are inputted through a D/A converter 2, an invertible amplifier 3 to comparators 4 and 5 and the comparators 4 and 5 compates the input signals with a threshold value from a voltage divider composed of resistors R11 and R12. The output of the amplifier 3 becomes negative when the output of the converter 2 is positive and when it exceeds the threshold value -V of the comparator 4, the comparator 4 generates the output, a transistor(TR) 6 is turned on and the power is supplied to a linear motor coil 12. Similarly, when the output of the D/A converter is negative and the positive output of the amplifier 3 exceeds the threshold value +V, the power is supplied to the coil 12. The current made flow to the coil 12 generates voltage drop in the resistor 14, the output of a differential amplifier 13 becomes nagative and the current of the coil 12 is stopped. Then, no feedback signal from the resistor 14 becomes to be present, TRs 6 to 9 are turned on again and operations are performed.

Title: Vehicular door lock control device
Inventor: SEGAWA KUNIO
IPC: E05B83/36
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To reliably perform unlocking, locking and locking restricting operation of a vehicular door lock control device by providing a control means to change the timing to turn on two relays among three relays by a prescribed time. SOLUTION: An S/L motor is driven in the U/L direction by turning on output voltage of a terminal B after prescribed time T1 by driving an N/L motor in the U/L direction by turning on output voltage of a terminal C. A locking mechanism is put in an U/L state when turning off the output voltage of the terminal B after passing prescribed time T3 by turning off the output voltage of the terminal C after passing prescribed time T2.  There is a fear of operating the S/L motor in the S/L direction by the output voltage from the terminal C when impressing the output voltage of the terminal B since there is generally an individual difference in required time of mechanical operation of contact points arranged in relays, but a malfunction can be reliably prevented by delaying the output timing of the terminal B by the prescribed time T1 more than the terminal C and also setting the prescribed time T1 longer than a nominal error. Operation to transfer to an N/L state and an S/L state is also the same.

Title: Power supply backup circuit
Inventor: SATO SATOSHI
IPC: H02J7/34
Filed: 1993-12-29
Abstract: PURPOSE:To detect without fail the removal of a battery loaded into an electronic equipment with a low operating voltage, such as pager, and make a power supply backup circuit deliver its intended function with reliability. CONSTITUTION:If a battery 2 is removed and intermittent drive starts in the receiving section 6 of a control section 5, voltage supplied to the control section 5 through a switching transistor Q1 is reduced. Thus the voltage between the battery terminals is reduced, and voltage supplied to a diode 7 is thereby increased to the on-voltage of a switching transistor Q2 to turn on Q2 and turn off the switching transistor Q1. The leakage current from the diode 7 and the receiving section 6 is reduced to a negligible extent, and the voltage generated between the battery terminals reduced to approx. 0V. When this voltage is detected through a voltage detecting circuit in the control section 5, it is judged that the battery 2 has been removed. This prevents the rapid discharge of a charging capacitor 4.
