Title: Semiconductor laser device
Inventor: WATANABE YUKIO
IPC: H01S5/00
Filed: 1989-12-28
Abstract: PURPOSE:To prevent the absorption of light near a light-emitting edge part at an active layer by a method wherein the band gap energy of the light- emitting edge face part at the active layer is made larger than that of a main light-emitting part of the active layer. CONSTITUTION:Stripe-shaped grooves are made on an n-GaAs substrate 10 whose main face is a plane 100; inclined faces 11 of planes 111 are formed to be stripe-shaped on the surface of the substrate. Consequently, since e.g. the planes 111 but not the plane 100, i.e., the groove-shaped inclined faces 11, exist on the substrate 10, the band gap energy of crystals grown on the inclines faces 11 becomes large. Thereby, light is not absorbed at a light-emitting edge face; it is possible to prevent the crystals from being melted by a positive feedback mechanism such as heat generated by the self-absorption of light or an increase in the absorption of light by a temperature rise; it is possible to enhance a maximum light output at a continuous operation.

Abstract: PURPOSE:To automatically release line connection by controlling a line connecting/disconnecting relay to be connected to a telephone type exchange line by means of signals obtained from a current detecting circuit, a busy tone detecting circuit, a ring-back tone detecting circuit, and a dial signal generating circuit. CONSTITUTION:When an operator leaves the position of a telephone set 1 by any reason after connecting the set 1 to the telephone type exchange line, the exchange line stops voltage feeding after the lapse of a certain time. Thereby, current undetection is detected by a current detecting circuit 12 and a line connecting/disconnecting relay control circuit 14 is controlled to reset the line connection. When telephone set 1 does not release the line connection though a terminating subscriber releases the line connection after temporarily ending speaking, a busy tone is outputted from the exchange line simultaneously with the opening of the line by the terminator and detected by a busy tone detecting circuit 7, a signal outputted from the circuit 12 is validated and the line connection is reset.
