Title: Input circuit
Inventor: INOUE MICHIYA
IPC: H03K17/78
Filed: 1988-04-28
Abstract: PURPOSE:To correspond to many types of power sources by inserting one current limiting circuit into the common line of an input circuit unit which constitute plural input circuits. CONSTITUTION:A current limiting circuit 3 is inserted into the common line of a power source 2 and an input circuit unit 1. When the voltage of the power source 2 rises, a current I1 increases, therefore, the voltage of a detecting resistance R2, that is, the base voltage of a transistor TRQ2 rises, and a collector current I2 increases in the circuit 3. The current I2 flows from the power source 2 through a resistance R1, therefore, the voltage drop of the resistance R1 increases, the base voltage of a TRQ1 falls and the current I1 is decreased. That is to say, the current I1 is controlled constant and a current I is also controlled almost constant. Consequently, when resistances of large calorific value are used for resistances R11-R1n in the unit, it is unnecessary to change their resistance values even when a power source voltage changes.

Title: Line signal receiving circuit
Inventor: SAKAI MASAYUKI

Abstract: PURPOSE:To obtain a line signal receiving circuit upon which the influence of an AC induced noise is difficult, by providing an AC induced signal by-passing filter circuit consisting of a capacitor and a resistance between the anode and the cathode of a photocoupler.

Values of the capacitor C and a resistance R2' are selected properly to set the value of the current I'FAC to a value smaller than a threshold current IFTH required for turning on the photocoupler PC thereby obtaining the line receiving circuit which is not affected by the AC induced noise.
