Filed: 1983-04-15
Abstract: PURPOSE:To control securely information on the maintenance inspection of a vehicle, etc., by counting pulses generated at every interval of unit distance, and generating a warning when the counted value attains to an expected value. CONSTITUTION:When the pulse signal generated at every interval of unit distance is applied to an input terminal 1, a run distance counter 2 starts counting run distance.

Title: Monitor displaying device for battery
Inventor: KOCHI HIROYUKI
IPC: G01R31/36
Filed: 1985-03-30
Abstract: PURPOSE:To prevent the overcurrent of a rating electric current of the light emitting diode without fail by increasing and connecting the resistance to the cathode of the light emitting diode while the charge is executed and when two light emitting diodes to display the abnormal condition simultaneously is light-emitted. CONSTITUTION:When a battery 2 is abnormal, a contact 4a of a monitoring circuit 4 is turned on, the electric current flows at the light emitting diode (red) and the light is emitted. Since the electric current of two light emitting diodes LES1 and LED2 are both distributed at a cathode resistance R1, the voltage drop of the resistance R1 is increased, the cathode side terminal voltage rises, a Zener diode ZD is turned on exceeding the Zener voltage, and therefore, a thyristor SCR is turned on and a transistor Tr is turned off. Thus, when two light emitting diodes LED1 and LED2 are both light-emitted, the high resistance is inserted and connected to the common cathode, and the overcurrent of the rating capacity is prevented without fail.

Title: Polarity inversion detecting circuit
Inventor: MITSUISHI TOMOYA
IPC: H04M1/00
Filed: 1987-03-24
Abstract: PURPOSE:To prevent the reductions of transmission loss and a trunk line voltage by using an FET as a switching element in the case of detecting polarity inversion so as to bring the impedance viewed from the trunk line into a high impedance. CONSTITUTION:When the voltage of a line 1 is larger than the voltage of a line 2, a current flows in the order of line 1   rectifier circuit 3   voice line 4   voice line 5   rectifier circuit 3   line 2. Thus, a potential difference is produced between the gate and source of the FET 10 and the FET 10 is turned on, then the photocoupler of a current detection circuit 20 is operated and a detection signal is sent to a data line 9. On the other hand, since the gate voltage of the FET 11 is not larger than the source voltage in this case, the FET 11 is not turned on and a current detection circuit 19 is not operated. Since FETs 10, 11 are used to detect a trunk line voltage, the impedance viewed from the lines 1, 2 is brought into the high impedance. Thus, the polarity inversion is detected without giving effect onto the line voltage and the transmission loss is reduced, as well.
