Title: Magnetostatic wave element
Inventor: MURAKAMI YASUHIDE
IPC: H01P1/215
Filed: 1990-09-05
Abstract: PURPOSE:To suppress the spurious mode over a wide range by roughing a part or all faces of an end of a medium through which a magnetostatic wave propagates. CONSTITUTION:Roughing is applied to an end of a magnetic film of a magnetostatic wave resonator in the lengthwise direction. Thus, no spurious mode is in existence in a range of + or -20MHz with respect to a major resonance in a frequency range of 5.0-5.5GHz in the resonator subject to roughing by abrasive grain whose grain diameter is 15mum or over in this way.

Title: Semiconductor laser
Inventor: MURAKAMI TAKASHI
IPC: H01S5/00
Filed: 1986-10-02
Abstract: PURPOSE:To obtain a window structure laser having small astigmatic difference by bringing a layer inverted to P-type by diffusing Zn near the end face of a laser to the vicinity of an optical guide of an active layer to form a refractive index difference formed in a direction parallel to a junction even at the end face. CONSTITUTION:The lower part of the groove of an active layer 3 is inverted to P type by the diffusion of Zn in a laser to enhance the refractive index to be controlled in a lateral mode, and a layer 8 inverted to P type by the Zn diffused during the growing of a P-type GaAs contact layer 7 through a shallow groove 10 arrives at approx. 0.1-0.5mum near the active layer in the vieinity of one end face. In this case, the active layer is not inverted to the P type, and its forbidden band width is not varied. That is, the forbidden band width of the active layer of the end face is larger than that of the active layer in the laser, and a window structure that a light irradiated in the laser is not absorbed by the end face is formed.

Title: Semiconductor device and its manufacture
Inventor: ISEDA TATSUYA
IPC: H01L21/265
Filed: 1993-09-24
Abstract: PURPOSE:To form continuous impurity areas having desired shapes at different depths in a semiconductor substrate by selectively patterning a masking material so that its end sections are tapered on the surface of the substrate and implanting the ion of an impurity into the substrate through the masking material. CONSTITUTION:A masking material 13 composed of a resist is formed on the main surface of a semiconductor substrate 11. The end sections of the material 13 are tapered by selectively patterning the material 13. Then impurity areas are formed in the substrate 11 by implanting ions into the substrate 11 through the material 13 on the main surface of the substrate 11 at high acceleration. When the implanting direction of the ions is made almost coincident with the tapered angle theta of the material 13, impurity areas 12a, 12b, and 12c are formed at different depths in the substrate 11. Since the thickness of the material 13 is not uniform, the forming depths of the areas 12a and 12c can be changed while the acceleration voltage of the ion implantation is fixed.

Title: Device for controlling gas turbine
Inventor: UCHIDA NORIHIRO
IPC: F23R3/28
Filed: 1992-08-14
Abstract: PURPOSE:To prevent a rapid increase in a fuel flow rate even when the tripping of a gas turbine in other systems occurs and a fuel pressure increases rapidly, by reducing an exhaust gas temperature preset value and subtracting a subtraction value for suppressing an increase in an exhaust gas temperature. CONSTITUTION:When a gas turbine in other systems is tripped, a subtraction command signal S2 is outputted to perform the operation of closing a switch 5e. According to this operation, a subtraction value 5d of a subtraction value setter is inputted into a subtractive directional variation rate limiter 5f, and an output from said limiter 5f and a signal from an exhaust gas temperature setter 5a are inputted into a subtracter 5k. An output signal from the subtracter 5k is added to or subtracted from a signal from a temperature detector 12, and the resultant value is inputted into a PID operation unit 5c, which adjusts an output of an exhaust gas temperature controlling device 5 in a reducing direction. As a result, a fuel flow rate controlling valve 8 is rapidly throttled. By this method, the gas turbine can be prevented from being tripped in a condition that an exhaust gas temperature exceeds a high limiting value thereof.

Abstract: PURPOSE:To eliminate need for rubbing and to facilitate patterning so as to simplify stages and to improve production efficiency by using a photosetting resin as an orienting agent soln. and fixing the orientation by projecting light thereto after formation of the orientation. CONSTITUTION:The photosetting resin is used as the orienting agent soln. and the orientation is fixed by projecting the light thereto after the formation of the orientation. For example, a substrate 104 is immersed into a treating liquid tank 100 in such a manner that the greater part thereof sinks in the orienting agent soln. 102 and is held in this state for 10min. The substrate 104 is then pulled upward in a vertical direction at 20mm/sec pulling-up speed. A light shielding plate 108 is so disposed as to parallel with the projection face of the substrate in the stage when the pulling-up and the drying of the solvent end. The light from an extremely high pressure mercury lamp 110 is projected in such a state to the oriented film 104a of the substrate through the light shielding plate 108 from the direction perpendicular to the plane of the plate 108. The oriented film 104a stuck with a photosensitive polyimide resin is then cured and the molecular arrangement in the vertical direction is fixed.

Abstract: PROBLEM TO BE SOLVED: To decrease the output fluctuation of a photo-sensor and to simplify the design, and also to improve the productivity, by forming a reflecting surface on the edges of a reflecting plate, in the direction crossing at a right angle the moving direction of the reflecting plate, shifting in the moving direction of the reflecting plate. SOLUTION: The reflecting plate 5, equipped with a reflecting pattern, is fixed ink a movable body 6, and a photo-sensor 7 of a reflecting type is installed in a fixed part 8, facing the reflecting plate 5. The movable body 6 usually moves in the X direction, and the spot on the reflecting plate 5, where emitted beam 9 from the photo- sensor 7 is irradiated, is changed. Only a part of the emitted beam 9 radiated toward the reflecting plate 5, which hits a reflecting surface 10 of the reflecting pattern, is reflected and enters a light-receiving part of the photo-sensor 7. And, a suitable width B is determined from the both edges of the reflecting plate 5 in the Y direction, then the pattern of this part is arranged, shifting in the X direction by a suitable length C.  The width B in the Y direction and the shifted length C in the X direction are determined most suitably, corresponding to the characteristics of the reflecting plate 5 and the sensor 7. Thereby, the displacement amount in the X direction can be detected stably.
