Title: Semiconductor laser device and manufacture thereof
Inventor: MORI YOSHIFUMI
IPC: H01S5/30
Filed: 1980-07-16
Abstract: PURPOSE: To prevent an unnecessary spreading of current and decrease a threshold value of current, by a method wherein the configurations of the current passage and light passage of a laser device are made sufficiently narrow, and the current reduction for limiting the current passage is performed in an active layer and in the vicinity thereof.  
     CONSTITUTION: On the surface of an N type GaAs substrate 1 whose crystal in the surfacewise direction is (100), a groove 2 having inclined surfaces 3 is formed by etching, and over the whole surface including this, an N type GaAs buffer layer 4 and an N type GaAlAs trapping layer 5 are epitaxially grown, in a laminating manner, following the groove 2. Then, thereon, a P type GaAs active layer 6 is formed having an energy gap width smaller than that of the layer 5, and inclined surfaces 13' parallel to the inclined surfaces 3 are formed, on which an N type GaAlAs trapping layer 7 is grown having a large energy gap. Thus, hetero junctions J 1  and J 2  resulting from the gap width differences are produced at the respective interfaces between the layer 6 and the lower layer 5 and between the layer 6 and the upper layer 7. At the same time, a P-N junction part J pe  is formed at the interface between the layers 5 and 6, and then, a P type GaAs layer 8 having a flat surface is grown on the whole surface.

Title: Auxiliary switching system of tdma communication system
Inventor: KOORI TAKEJI
IPC: H04B7/212
Filed: 1979-07-31
Abstract: PURPOSE:To make it possible to switch the communication signal from the current TDMA (time division multiple access) unit to the auxiliary TDMA unit without initial action operations of the auxiliary TDMA unit for the fault of the current TDMA unit, by synthesizing burst of current and auxiliary systems by the output of the transmitter. CONSTITUTION:Transmission outputs of TDMA units TDMA1 and TDMA2 are synthesized by hybrid HYB1 and are branched into two by HYB2, and respective branched outputs are amplified by transmission units HPA1 and HPA2 after converted to radio frequencies by transmission output converters U/C1 and U/C2. These outputs are synthesized by hybrid HYB4 and are transmitted to a satellite through branching filter WSF from antenna ANT. The signal from the satellite is converted to an intermediate frequency by receiving frequency converter D/C1 or D/C2 after low-noise amplifier LNR1 or LNR2 is selected by switch SW1, and this frequency is input to the receiving inputs of TDMA1 and TDMA2 through switch SW2 and HYB2.

Title: Multistage type rotation transmission mechanism
Inventor: ITOU GENJI
IPC: F16H7/02
Filed: 1980-07-18
Abstract: PURPOSE: To promote the accuracy to transmit motion in a multistage type rotation transmission mechanism by providing extension-absorbing devices mutually related on at least two of endless ropes belonging to different transmission elements.  
     CONSTITUTION: Extension-absorbing devices 92 and 94 are respectively arranged on the way of endless ropes 32 and 34. The extension-absorbing devices 92 and 94 are respectively constructed by connecting a cylinder 901 and a piston 902 between a chain 301 and a nonflexible element 302 via a spring 903. When extension is absorbed by the extension-absorbing device 92, the rotational phase of a driven side wheel 42 to a driven side wheel 22 is changed. The change of its output is counterclockwise and positive. When extension is absorbed by the other extension-absorbing device 94, a driven side wheel 44 is rotated clockwise to change the output into negative. Consequently, the positive and negative outputs of both rotational phases offset each other for reducing the injurious change of the outut.

Abstract: PURPOSE:To enable the gelation of ClO2 at ordinary temp. and to obtain a stable gelled product of ClO2 consisting of prescribed percentages of sodium alginate, a Ca salt and ClO2 and the balance water. CONSTITUTION:This gelled product of ClO2 consists of, by weight, 1-5% sodium alginate, 0.1-5% Ca salt such as CaCl2, 0.5-4% ClO2 and the balance water. An aqueous soln. of sodium alginate and a mixed soln. contg. said Ca salt and ClO2 are prepd., and the solns. are mixed at ordinary temp. to obtain said gelled product. This gelled product is obtd. in a short gelation time, and the gel is hard and stable. It is, however, probable that water separates from the gel surface when the gelled product is allowed to stand for about 24hr, so it is required to add a water separation inhibitor and a gelation retarder.

IPC: H02M1/00
Filed: 1981-06-22
Abstract: PURPOSE:To obtain a small-sized and inexpensive SCR bulb by monitoring a current flowing through an arrester, and eliminating the application of a firing signal to the SCR when the current value exceeds a set value, thereby unnecessitating a large reactor for protecting the SCR. CONSTITUTION:A firing circuit 7 of an SCR1, a monitoring unit 8 for monitoring a current of an arrester 3, and a switch 9 which is inserted between the firing circuit 7 and the gate of the SCR1 and which opens or closes in response to an arrester current signal inputted from the unit 8, are provided. The switch 9 is operated to close in an ordinary state and when the current of the arrester 2 is lower than the prescribed set value and to open when the current exceeds the set value. In this manner, the current of the arrester 2 is monitored by the unit 8, and the switch 9 is opened when the current value exceeds the set value. Thus, a firing signal is not applied to the SCR1, a surge current continuously flows through the arrester 2, and is gradually attenuated.

Title: Diaphragm for speaker and its production
Inventor: NOGUCHI HIROTOSHI
IPC: H04R7/02
Filed: 1979-08-01
Abstract: PURPOSE:To make it possible to obtain a light-weight and large-internal loss diaphragm, by using a polyurethane, which has independent bubbles of a higher foaming magnification toward the center, as the diaphragm. CONSTITUTION:Diaphragm 3 is formed with a polyurethane which has independent bubbles of a higher foaming magnification toward the center. Therefore, diaphragm 3 is low-density and light-weight and has a three-dimensional structure, so that stiffness can be improved and elastic modulus and internal loss can be high in diaphragm 3. For production of this diaphragm, isocyanate, polyol, and a blowing agent are mixed, and this liquid material is injected into a closed mold immediately. In this closed mold, polymerization reaction is caused to form a polyurethane, and the blowing agent is decomposed by heat generated at this time. In this case, the polyurethane is hardly foamed in parts brought into contact with the closed mold and forms independent bubbles of a higher foaming magnification toward the center because the temperature of the closed mold is low.

Abstract: PROBLEM TO BE SOLVED: To protect a joint part by forming this side part of the joint part in the advancing direction of a vehicle as an ascending gentle slant, and forming the joint part like a descending slope. SOLUTION: Generally in the case of providing a joint part 2 in a pavement formed by a paving part 1, an ascending gentle slant part 3 is formed on this side of a joint 2 in the advancing direction of a vehicle, and the joint 2 is formed like a descending step or slope.
