Abstract: PURPOSE:To prevent the overvoltage in the case a battery is turned OFF by connecting resistance and a capacitor between a base of a transistor to control a gate of a thyristor supplying DC to a battery and a battery load and an earth. CONSTITUTION:In normal time of a fuse 5, the voltage of a tap 1b of a generator 1 charges a battery 3 through a thyristor 10, and is fed to a battery load 4. In the case the fuse 5 is cut off, the voltage of the tap 1b of the generator 1 is applied to a cathode of a Zener diode 8 through resistance 9 and a diode 14, and reaches the voltage higher than the emitter voltage of a transistor(Tr) 11.

Simultaneously, a capacitor 17 is charged from an anode of the thyristor 10 through resistance 16. While the voltage of the tap 1b is negative, the capacitor 17 discharges. Accordingly, the overvoltage of the battery load 4 is prevented.

Title: Gain coupled dfb laer and its manufacture
Inventor: KAKIMOTO SHOICHI
IPC: H01S5/323
Filed: 1992-11-19
Abstract: PURPOSE:To achieve a high-yield manufacture of a gain coupled DFB laser whose characteristic is even by a method wherein first absorption regions and second absorption regions are arranged periodically on an n-type clad layer. CONSTITUTION:An n-type clad layer 3 is formed on an active layer 2 formed on a substrate 1. Then, p-type InGaAsP absorption layers 4 are formed on it at definite intervals, and they are buried completely by an n-type InGaAsP absorption layer 5. The absorption loss factor of the p-type InGaAsP absorption layers 4 is comparatively large, and the absorption loss factor of the n-type InGaAsP absorption layer 5 is comparatively small. Consequently, first absorption regions whose absorption loss factor is comparatively large and second absorption regions whose absorption loss factor is comparatively small are arranged alternately at a definite cycle on the active layer 2 via the clad layer 3. Since their characteristic and their yield are decided by three parameters, i.e., the thickness l1 of the active layer 2, the thickness l2 of the clad layer 3 and the thickness l3 of the absorption layer 5, the characteristic of the title laser is controlled easily, and the yield of the title layer becomes high.
