Title: Driving circuit for latching type switch
Inventor: MORI HITOSHI
IPC: H04B1/44
Filed: 1981-07-06
Abstract: PURPOSE:To shorten the repetitive operation time of a circuit by preventing a discharge current from being supplied from a power source to a capacitor for the charging and discharging of a driving current for a latching type switch during the instantaneous discharging operation of said capacitor. CONSTITUTION:In the driving circuit 30 wherein driving coils of latching type switches are connected to terminals 1 and 2, capacitors C1 and C2 are charged in a stationary state up to voltages E1 and -E1 through switches S1 and S2 and resistances R1 and R2, and capacitors C15 and C25 are charged up to voltages which correspond to the anode-cathode potential differences of thyristors D1 and D2. In this state, when a switching indication signal SO1 is applied to a terminal 7, the switches S15 and S1 are turned on and off respectively and the charge of the C15 turns on the thyristor D1, so that the charge of the C1 controls an unshown switch between the terminals 1 and 2. At this time, the charge path from the power source +E1 of the C1 is cut off by the S1, so a resistance R1 is reduced to shorten the repetitive operation time of the circuit.

Title: Light emitting element bias current superimposing circuit
Inventor: ARAI TAKATERU
IPC: H04B10/07
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To inexpensively obtain a circuit increasing a bias current with raising the temp. by inserting a circuit network consisting of a resistor and a resistor having a negative temp. coefficient so as to superimpose a bias current to a semiconductor light emitting element. SOLUTION: A light emitting element driving circuit 3 demodulates a semiconductor light emitting element 1 by a pulse signal or an AC signal. A negative temp. special circuit network 2 allows the current of a level obtained by dividing a level, which is obtained by subtracting the portion of voltage drop by the element 1 from the voltage of a voltage source by the composite resistance or the equivalent resistance of the network 2 to flow from the anode side of the element 1 to a cathode side. The portion of voltage drop by the element 1 is almost equal to the threshold voltage (Vth) of a diode in a small current value, constant and small in temp. dependency. Consequently, by varying the composite resistance of the network 2, a bias current to be made to flow to the element 1 is variable.  Then, when temp. is raised, the network 2 reduces its composite resistance to increase a bias current to flow through the element 1.
