Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser substrate which can be cleaved while suppressing defective cleavage, e.g. chipping or cracking, significantly. SOLUTION: A clad layer 4, an active layer 5 and a clad layer 6 are laminated sequentially on a substrate 2, a current constriction layer 8 is formed on the clad layer 6 by constricting a stripe-like clad layer 7 and a contact layer 9 is formed on the clad layer 7 and the current constriction layer 8 to produce a laser substrate 1. Flaws 121 , 122 , 123 are formed in the end face of the substrate 2 on one side 1a of the laser substrate 1 substantially perpendicularly to the forming direction of the clad layer 6 and the laser substrate 1 is cleaved along cleavage grooves generated from the flaws 121 , 122 , 123 thus producing laser bars 13. The laser bar 13 is divided in a direction different from the cleavage groove direction into a plurality of sections thus forming laser elements 15.  A recess L is made on the contact layer 9 at the intersection of the cleavage groove direction and the clad layer 6 forming direction.

IPC: H04M1/03
Filed: 1987-04-27
Abstract: PURPOSE:To facilitate the assembling and to realize the cost reduction effect by arranging a receiver and a transmitter to the transmitter side unifiedly and delivering the sound of the receiver through the forming of a sound guide of a housing of a handset. CONSTITUTION:The transmitter 4 and the receiver 3 are placed to the side of the transmitter of a handset housing 1. The sound wave coming from sound holes 14 of the transmitter side is converted by the transmitter 4 into an electric signal and sent to a telephone set through a wire cord 11 and a modular connector 6. The receiving signal from the telephone set enters the receiver 3 via the connector 6 and the cord 11 and is converted into the sound wave, which reaches the receiver side sound hole 15 via a sound guide 13 of the housing 1 and is delivered to a recipient. Thus, the unification of the receiver and the transmitter is facilitated and a short wiring from the connector is enough for the handset. Since it is not required to interconnect the wire cord in the housing, both material cost and assembling cost are reduced.
