Title: Semiconductor laser diode
Inventor: IKUWA YOSHITO
IPC: H01S5/00
Filed: 1983-10-31
Abstract: PURPOSE:To lessen the current of a threshold value, and moreover to realize the titled diode with current-optical output characteristics, by which the diode can go so far as to favorably output higher photo output, by a method wherein a first conductive-type impurity diffusion region is formed at the common prescribed position of a second clad layer and an optical waveguide layer in such a way that its diffusion tip doesn't reach an active layer. CONSTITUTION:When inpurities are added to a GaAlAs layer in high concentration, its forbidden band width becomes narrower by a band tail effect. For example, in a Ga0.8Al0.2As layer, the forbidden band width of its P type high-concentration impurity diffusion region becomes narrower by 0.04-0.08eV, compared to the forbidden band width of its non-diffusion region. As a result, the forbidden band width of an optical waveguide layer 8 (an N type Ga0.81Al0.19As layer), which is a non-diffusion region, is wider by about 0.4eV, compared with the forbidden band width of an acive layer 3, but the forbidden band width of the part of a P type impurity diffusion region 9 consisting of a P type Ga0.81Al0.19As layer, wherein P type impurities of 10<19>-10<20>/cm<3> have been diffused, becomes equal with the forbidden band witdth of the active layer 3 or becomes narrower than that of the active layer 3. Accordingly, the part of the P type impurity diffusion region 9 consisting of the P type Ga0.81Al0.19As layer functions as an absorption region of laser beams, which generates at a luminous region (a), and light in the parallel direction to the active layer 3 is confined under the luminous region (a), where the P type impurity diffusion region 9 has not been formed.

Abstract: PURPOSE:To prolong the battery life for operating an electric apparatus, by controlling each switching means between a power line to the electric apparatus and a plurality of batteries. CONSTITUTION:When a terminal voltage of battery 2 and a terminal voltage of a battery 3 are equal to each other, a switching transistor 6 is turned on and switching transistors 11 and 12 are also turned on by a microcomputer 7 so that the power from the batteries 2 and 3 is not carried through a diode 4 or a diode 5 but directly fed to a system controller 1. When the terminal voltage of the battery 2 is higher than that of the battery 3, the switching transistor 11 is turned on and at the same time the switching transistor 12 is turned off by the microcomputer 7 so that the power from the battery 2 is not carried through the diodes 4 and 5 but directly fed to the system controller 1. As a result, the power is supplied without a decrease in voltage caused by the diode.

Filed: 1989-08-11
Abstract: PURPOSE:To make thinner a solution wave formed on an inner wall of pipe and hence improve the efficiency of heat exchange by installing a separation means which separates refrigerant gas from condensation solution on the way of a refrigerant passage. CONSTITUTION:The refrigerant introduced into a connection member 1 by way of a refrigerant intake pipeline 33 enters each zigzag pipeline 3 and 3' and enters each air-liquid separation chamber 31 and 32 from pipe openings 3d and 3d' on the front stage pass side. The refrigerant which has entered the separation chamber is separated into gas and condensed solution. The condensed solution flows down ward by way of a flow passage pipelines 15 and 17, and flows into a float chamber 6 where the gas enters the next passage from each pipe opening 3e and 3'e. The refrigerant in the passage is gradually liquefied and completely liquefied near a connection member 2, and flows into the connection member. The liquid film formed on the inner wall of the pipe accompanied by this liquefaction is reduced in terms of its thickness since the liquefaction starts under a gaseous state where the condensed solution at the front stage is excluded at the starting point.

Abstract: PURPOSE:To grasp the defective state of a spare row (column) before replacement by giving a signal of a test signal means to the spare row (column) when a test signal is inputted and giving a signal of a spare decoder to the spare row (column). CONSTITUTION:When an H level is inputted as the spare row (column) selection signal, an output of a OR gate 6 goes to a H level independently of the level of a selection line 2 connected to other terminal of the OR gate 6 depending on the property of the OR gate and the spare row (column) desired for the operation test is selected forcibly. In applying the operation, an operation test selection pad 7 to the L level or floating state, the state inputted from the other terminal, that is, the state of the selection line 2 is outputted as it is. That is, the state of the operation test selection pad 7 is outputted as it is from the OR gate 6 at the operation test and the state of the selection line 2 is outputted as it is from the OR gate 6 at the normal operation.Thus, the defective state of the spare row (column) before the program of the spare decoder is grasped easily.
