IPC: G01C19/72
Filed: 1989-06-14
Abstract: PURPOSE:To realize a high output and a low coherence by a method wherein an active layer is formed from the front of a chip to a certain region at its inside and a region between its rear and the back of the chip is filled with a semiconductor material whose forbidden band width is larger than that of the active layer. CONSTITUTION:A p-Alx1Ga1-xAs clad layer 12, a p-Alx2Ga1-x2As active layer 13, an n-Alx1Ga1-x1As clad layer 14 and an n-Alx3Ga1-x3As layer 15 are laminated on a p-GaAs substrate 11. In addition, an n-Alx4Ga1-x4As layer 16 and an n-GaAs contact layer 17 are formed so as to be piled up; a U-shaped Al2O3 insulating layer 18 having a stripe shorter than the active layer 13 from a front-end face is formed on the surface; after that, electrodes 19, 20 are executed on both the surface and the rear surface; in addition, low-reflectance coating films 21, 22 are executed on both the front face and the back face. Thereby, an effective reflectance at the back side is reduced; it is possible to obtain a high-output superluminescent diode which can be used for an optica; fiber gyroscope.

Title: Wire saw and recording medium
Inventor: FUKUDA KOJI
IPC: B28D5/04
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To provide a wire saw which can improve the cutting efficiency. SOLUTION: A carbon 24 is installed to the upper surface of a work 21. The carbon 24 covers all the outer peripheral surface of the upper part at the center of the cross section of the work 21. The angles AL and AR made by the both side walls 24a of the carbon 24 and a wire 16 are made in an acute angle. As a result, even when the wire 16 is positioned at the upper part higher than the center of the cross section of the work 21, a slurry can be stayed between the both side walls 24a of the carbon 24 and the wire 16. Consequently, the cutting efficiency of the work 21 can be improved because the slurry is fed to the wire 16 securely.

Title: Shunt part constrictor for dialysis
Inventor: OTA MICHIO
IPC: A61M1/14
Filed: 1990-06-07
Abstract: PURPOSE:To easily and precisely open and close a shunt part by providing an oppressor confronted with the shunt part being mounted on a supporting ring in such a way that it can be moved reciprocally freely and closing the shunt part by oppressing by the forward movement and opening the shunt part by releasing oppression by the backward movement. CONSTITUTION:A grip handle 3 is fixed on one terminal part of a setscrew 2 facing with the outside of the supporting ring 1, and the oppressor 4 is mounted at another terminal part facing with the inside of the supporting ring 1, and it is formed in such a way that it can be moved forward/backward freely in the inside/outside direction of the supporting ring 1 by operating the grip handle 3. When the supporting ring 1 is loaded on the front arm part of a patient receiving dialysis and artificial dialysis is started, the oppressor 4 is moved to a shunt part side by operating the grip handle 3, which oppresses the shunt part and closes it. Blood resistance in the shunt part is increased, and a shunt blood flow rate is decreased, and an effective body circulation blood flow rate can be maintained, thereby, the reduction of blood pressure can be suppressed. After the artificial dialysis is completed, the opening of the shunt part is performed gradually by operating the grip handle 3 moderately. The blood resistance in the shunt part is decreased gradually, and the blood flow rate can be recovered to a required shunt blood flow rate.

Title: Grain screening apparatus
Inventor: YAMAMOTO SOICHI
IPC: B07B4/08
Filed: 1994-06-08
Abstract: PURPOSE:To sweep out residual rice through a gap by installing a gap-filling body, which engages with a gap when it descends and forms the gap to sweep out residual rice when it ascends, in the gap so that the body can slide freely on the inner surface sides of the side walls on the swing-up side and the swing- down side. CONSTITUTION:The supply side 19 of a screen is slanted longitudinally and laterally to be higher than the discharge side 20, while the swing-up side 21 is slanted likewise to be higher than the swing-down side. On the screen, slender pooling boards 34, which are arranged horizontally at specified intervals, are supported by forming a gap 35 on the horizontal side. A gap-filing body 35a, which engages with the gap 35 when it descends and forms the gap 35 to sweep out residual rice when it ascends, is installed in the gap 35. The body 35a is installed freely vertically slidably on the inner surface side of a side wall 35b on both swing-up side 21 and swing-down side 2. Consequently, at the finish of operation, a large amount of grain remains on the screen, but the gap is formed by the vertical movement of the body 35a so that the residual rice can easily be wept out.

Title: Flip-flop circuit
Inventor: FUNAKOSHI YOSHIHIRO
IPC: H03K3/037
Filed: 1981-09-24
Abstract: PURPOSE:To prevent the pulse width of a reset signal of an output waveform from being prevented, by picking up a signals resetting a static type FF circuit, from an inverted output of the FF circuit operated with two-phase clocks. CONSTITUTION:When a transfer gate B having a clock terminal phi2 is closed and an output terminal Q goes to H level, an output of a 2-input NOR circuit 2 is fed back to an inverter 1 through a feedback resistor 3. In this case, as far as an output -Q of the inverter 1 does not completely goes to L level, a 2-input NOR circuit 6 does not goes to H level. Thus, since two-input NOR circuits 2, 2' are not quickly reset, the width of the Q output is not made narrow, allowing to obtain an FF circuit which can completely reset external counters.

Title: I-shaped plunger solenoid
Inventor: HOZUMI KAZUHIRO
IPC: F16K31/06
Filed: 1981-09-24
Abstract: PURPOSE:To obtain an I-shaped plunger solenoid having a movable iron core with a  high return stability thereby to make it possible to raise the response reliability of an  electromagnetic valve, by forming subdividing grooves in a magnetically attracting surface of either one of the movable iron core and a fixed iron core. CONSTITUTION:A movable iron core 1 has a vertical groove 3 for exhaust, a cylinder 8  resiliently pressed by a compression coiled spring 5 and receiving a hard rubber exhaust valve 7, and a spider's web-shaped magnetically attracting surface subdividing  groove 63, formed on a magnetically attracting surface 6, constituting divided magnetically attracting surfaces 62 each having a small area by ripple-shaped annular grooves  60 and radial grooves 61. While being in a magnetically attracting relation to a magnetically attracting surface of a fixed iron core, the attracting surface 6 is in a pressurized state since air flows into the annular grooves 60 and the radial grooves 61 of  the subdividing groove 63 from the cylinder 8 and the vertical groove 3. Therefore, the  synergistic effect of the magnetically attracting relationship therebetween and the pressurized state overcomes the fluid pressure resulting from generation of a seal region,  thereby allowing a high return stability of the movable iron core when an electromagnetic coil is deenergized to close the valve. Accordingly, it is possible to largely improve the response reliability in the valve function.
