Title: Light emitting element driving circuit
Inventor: OKADA HIROSHI
IPC: H03K17/78
Filed: 1988-02-15
Abstract: PURPOSE:To reduce a noise and to prevent malfunction from being generated in a peripheral circuit by connecting a light emitting element to a constant current circuit in series for a power source, and connecting a switching element which responds to an input signal to the light emitting element in parallel. CONSTITUTION:When a transistor(TR)2 is turned OFF, that is, the level of the input signal is L, the light emitting element 3 is constant current-driven and emits light by the constant current circuit 1. When the TR2 is turned ON, that is, the level of the input signal is H, since a voltage to be impressed on the light emitting element 3 is decreased, the current scarcely flows on the light emitting element 3, then, a quenching state is generated. Therefore, it is possible to keep the current on a light emitting element driving circuit constant even when the element 3 is driven by a pulse signal, and to reduce the noise on a power source line.

Abstract: PURPOSE:To reduce the effect of disconnection of line, by the downward branch communication line in branch communication lines, auxiliary downward branch communication line, and managing communication line coupling the managing device coupled with the master station and the auxiliary managing device coupled with the auxiliary master station. CONSTITUTION:If there is open line in the branch communication lines 6, the master station 4 and the auxiliary master station 7 detect the decrease in the voltage of carrier mutually to confirm the open line of the lines 6 through managing lines 11, 12.

If there appears a slave station which does not respond to the call of the master station 4, the downward communication line termination resistor 33 is inserted to the line 8 with the instruction of the master station 4 at the slave station located just before it. Thus, the range in which the communication is enabled is extended at the disconnection of the line 6 and the effect of disconnection is decreased.

Abstract: PURPOSE: To prevent the element destruction dependent upon thermal expansion by forming the element junction part and the lead by individual materials and joining the element junction part to a part of the lead so that the junction part surface  and the lead surface may be parallel to each other.  
     CONSTITUTION: Lead 2 is formed by plating copper or iron nickel with gold. Eelement junction part 4 is formed by Mo, W or alumina ceramic obtained by metallizing Mo or W.
