Title: Semiconductor laser protective circuit
Inventor: MATSUDA NOBUHIDE
IPC: H01S5/042
Filed: 1989-05-19
Abstract: PURPOSE:To protect a semiconductor laser even from a forward excessive current and a surge current by a method wherein a resistor is connected to the semiconductor laser in series, and a Zener diode is connected, in polarity opposite to that of the semiconductor laser, in parallel with the circuit composed of the resistor and the semiconductor laser connected in series. CONSTITUTION:A semiconductor layer 4 is connected with a current limiting resistor 5 in series, a Zener diode 6 is connected, in polarity opposite to that of the semiconductor laser, in parallel with the circuit composed of the resistor 5 and the semiconductor laser 4. Moreover, a constant current is made to flow by a constant current drive circuit 7 to enable the semiconductor laser 4 to emit laser rays. At this point, even if an excessive current flows through the semiconductor laser 4, the voltage between both the ends of the semiconductor laser 4 and the resistor 5 exceeds the reverse voltage of the Zener diode at a certain current or above and the current flows through the Zener diode 6, so that the semiconductor laser 4 is protected against breakage. By this setup, even if an excessive current or a surge current is applied to a semiconductor laser, the laser is hardly broken.

Abstract: PURPOSE:To prevent undesired transmission due to a fault of a start request signal line by providing a control means judging the presence of a change in the start request signal line or a transmission data signal line and preventing a transmission section from going to the starting state when there is no change in existence. CONSTITUTION:When a control section 1 changes the start request signal line 11 from the no request state into the requesting state, A monostable multivibrator 12 detects a change in the signal line 11 to change a function input signal line 13 into the starting state. Moreover, the control section 1 in desiring to continue the transmission generates a change in the signal line 11 repetitively to hold the output of the monostable multivibrator 12 onto the signal line 13. On the other hand, when the control section 1 desires to stop the transmission, the control section 1 holds the output of the signal line 11 so as not to generate a change in the signal line 11, then a signal appearing on the signal line 13 connecting to a terminal Q of the monostable multivibrator 12 is restored in the halt state after a prescribed time depending on the resistance R and the capacitance C. Furthermore, if no change is caused in the signal line 11, no starting state is caused even when the state is in requesting or non requesting.
