Title: Control method of battery charger
Inventor: YAMADA YUICHI
IPC: H01M10/44
Filed: 1990-03-20
Abstract: PURPOSE:To control a battery charger by making the output voltage of said charger constant when the output current of the charger is smaller than a predetermined value, by giving drooping characteristics to the output voltage- output current of said charger when the output current is higher than the predetermined value, and by displaying the generation of overcurrent when the output current is higher than another predetermined value. CONSTITUTION:An overcurrent detection circuit 8 refers to the output value of a current transformer CT to examine whether the output current of a battery charger 1 is higher than a predetermined value IOCP. When the output current of the charger is higher than the predetermined value IOCP, a drive circuit 10 is controlled to give drooping characteristics to the output voltage-output current characteristics of the charger 1. A control for making the output voltage of the charger 1 constant is performed when the output current of the charger 1 is lower than the predetermined value IOCP. Also, the overcurrent control circuit 8 outputs an overcurrent alarm signal of a predetermined value when the output current of the charger 1 is higher than a predetermined value IOCP1.

Title: Alarm device
Inventor: FUNAKOSHI NORIHIRO
IPC: G08B15/00
Filed: 1995-03-06
Abstract: PURPOSE: To prevent a forcible entry by an alarm sounding when an alarm inhibition code known only in person is not input within a specific time after unlocking. CONSTITUTION: Detection objective of a monitoring mode in an alarm device is unlocking or not of a lock. When a person as user returns to his home and unlocks a key for a door, this unlocking is detected by an unlocking detection portion 10. A first timer T1 is thus set, so that counting of one minute is started. During the time, the person opens the door and inputs an alarm inhibition code placed indoors to an alarm inhibition code inputting portion 30. Counting by the first timer T1 is then stopped and the device returns to the monitoring mode. In the case when an unlawful intruder enters and unlocks the key unlawfully, this unlocking is detected by a door release-opening detection portion 40. When an alarm inhibition code is not inputted, when the one minute counting by the first timer T1 finishes, a signal is outputted to a driving portion 24 from CPU 21. A buzzer B is thus operated so that an alarm is sounded.

Title: Image forming device
Inventor: INUTSUKA TSUNEKI
IPC: G03G15/20
Filed: 1979-06-08
Abstract: PURPOSE: To make possible accurate detection of the disconnection of a temperature detecting element with a simple constitution even when the copying machine is in a low-temeprature state by inhibiting the operation of a disconnection detecting circuit for a fixed time for the beginning of starting of heating the material to be heated such as roller and making its detection possible after a fixed time.  
     CONSTITUTION: Upon turning on of a main switch, electric power is supplied to a heater H21, and the resistance value of the thermistor TH21 decreases gradually. At the same time, C21 for timer for inhibiting the detection of disconnection is charged. The output of an operational amplifier Q21 is H. When the voltage of the C21 has been sufficiently charged, the Q21 becomes L at the time of t 1  and causes the disconnection detecting circuit to operate. If the thermistor TH21 becomes lower than the preset resistance value when there is no disconnection, WAIT becomes H at the time of t 2 . If there is a disconnection, the base of Q25 becomes H at the time of t 1  and the anode of D27 becomes L, by which the electric power to H21 is cut off like the dotted line and the WAIT signal is held L, thus the copying start is inhibited. In this way, the disconnection of the temperature detecting element may be accurately detected by the simple constitution even in a low-temperature state.

Abstract: PURPOSE:To prevent the playing state without a record disc, by inhibiting the turning of turntable at the application of power supply, in response to the output of the rest detection means to detect the rest position of the tone arm. CONSTITUTION:The output of the integrating circuit 1 to integrate the power supply voltage and the signal of the rest detection means to detect the rest position of the tone arm are input to the logical product gate 3, and the means 7 detecting the state of end of lifting up of the tone arm and the signal of the rest detection means 4 via the inverter 5 are input to the logical sum gate 6. Further, the outputs are taken as the set and reset input of the flip flop 8 to drive the phonomotor 10. Accordingly, even if the tone arm lifts down with the power supply in error without a record disc, since the rotation of the turntable is blocked, the damage to stylus tip can surely be prevented.
