Abstract: PURPOSE:To attain the reduction of gate resistance and the shortening of gate length simultaneously by selectively depositing a gate material on a first insulating layer and in the recessed section of a semiconductor substrate in response to the shape and size of a window for a resist while using a resist layer as a mask and removing the resist layer. CONSTITUTION:An SiO2 layer 15 is etched selectively by an isotropic etching liquid while employing a photo-resist layer 16 as a mask. A GaAs active layer is etched selectively while using the photo-resist layer 16, the SiO2 layer 15 and an Si3N4 film 14 as masks. Aluminum is deposited on the whole surface from the upper section of the photo-resist layer 16. The photo-resist layer 16 functions as a mask at that time, and aluminum layers having shapes and size corresponding to the window 16 are shaped onto the Si3N4 film 14 and a recess 19 in the GaAs active layer 11 in a window 18 and the opening 19. When the photo-resist layer 16 is removed, the aluminum layer on the layer 16 is also removed, and only a gate electrode 20 is left selectively.

Title: Abrasion monitoring method of piston ring and device thereof
Inventor: OKABE MASAHIKO
IPC: F02F5/00
Filed: 1990-09-14
Abstract: PURPOSE:To monitor always an abrasion amount during operation, by detecting the thickness in a diameter direction on the basis of a time difference in reception respective reflected waves coming from the outer and inner circumference surfaces, in supersonic wave which is transmitted from the outer circumference surface of a cylinder liner. CONSTITUTION:Ultrasonic wave is transmitted from a cylinder liner outer wall 5 toward a piston ring 2. The thickness (T) of the piston ring 2 in the diameter direction is detected on the basis of a time difference in reception between reflected wave which is reflected oh the piston ring outer circumference surface 6 and reflected wave which is received by an ultrasonic wave sensor 3. It is thus possible to know always abrasion state of the piston ring 2 from the outside of an engine without inspecting by opening the engine.

Title: Interruption load decentralizing circuit
Inventor: HIRATA MASARU
IPC: G06F9/48
Filed: 1993-09-30
Abstract: PURPOSE:To reduce the load on software and shorten the processing time by controlling the interruption of serial data, which are inputted from (n) external I/Os, on a hardware base. CONSTITUTION:A transmission selecting circuit 4 which receives (n) of, at the most, request-to-send signals 14-1 to 14-n from external I/O circuits 5-1 to 5-n selects one of the (n) of request-to-send signals by scanning the signals fast in order. The circuit sends back a request-to-send response (OK) signal accepting the request to send for the selected request-to-send signal and a request-to-send response (NG) signal negating the requests to send for other request-to-send signals. An external I/O circuit having received the request-to-send response (OK) signal enters a clear-to-send state and sends serial data to a corresponding serial control circuit among 3-1 to 3-n. Serial control circuits send interruption request signals 12-1 to 12-n to an interruption arbitrating circuit 2. The interruption arbitrating circuit 2 sends an interruption signal 11 to a control circuit 1, which performs an interruption process, so that no next interruption is initiated until this interruption process ends.

Abstract: PURPOSE:To detect the inclination of, e.g. a video camera and the like readily with a simple structure. CONSTITUTION:A balancer 8, which is a balanced body, is pivotally supported with a holder 5 of a video camera. A photointerruptor 11, which is a detecting body, has a light emitting element 12 and a photodetector 13 with a notch part 14 in-between. The detecting body 11 is arranged so that the horizontal part of the balancer 8 is put in and taken out of the notch part 14. An image sensing element 20 is rotated by the rotation of a gear 2a. A servo circuit 16 for controllintg a motor 15 with the detecting body 11 is provided. When the camera is inclined, the horizontal part of the balancer 8 is put in and taken out of the notch part 14. Since the output of the detecting body 11 is changed, the image sensing element 20 is controlled so as to become the horizontal state with the servo circuit 16. Therefore, the image sensing surface of the image sensing element 20 can be kept at the horizontal state all the time. Thus, the incliitatioit of the regenerated image is eliminated, and the image becomes easy to observe. Furthermore, the inclination of the camera can be readily detected with the simple structure of the balancer 8 and the detecting body 11.

Title: Starting method and device for two-stage reheat steam turbine plant
Inventor: HATANO ETSUICHI
IPC: F01K7/24
Filed: 1987-09-30
Abstract: PURPOSE:To improve controllability of the turbine plant in the caption and to restrain the exhaust pressure rise of a superhigh-pressure turbine in starting the turbine plant, by providing a first and a second exhausters for connecting the exhaust sides of the superhigh-pressure and a high pressure turbines respectively to a condenser through a first and a second closing gears. CONSTITUTION:A reheat steam governing valve 23b for an intermediate- and a low-pressure turbines 11, 13 is first opened, so that a part of reheat steam is fed into the intermediate turbine 11 to rotate it until its speed becomes a given constant value. In this case, since both the internal pressure of a superhigh-pressure turbine 3 and that of a high-pressure turbine 7 are approximately vacuous, their windage losses are not generated, and the superheated conditions of their exhausts can be restrained. As a result, only those turbines 11, 13 are simultaneously monitored, so controllability can be improved. Then exhaust valves 42, 44 are fully closed as soon as governing valves 22, 23a for the turbines 3, 7 are opened. Consequently, the starting of the turbine plant concerned is carried out while main steam or reheat steam is fed respectively into turbines 3 and 7 so as to increase load together with air flow.

Title: Fm demodulator
IPC: H03D3/00
Filed: 1991-08-30
Abstract: PURPOSE:To prevent increase in noise and to prevent inversion by setting a reference level signal at zero cross point count to a signal obtained by applying low pass filtering to an FM video signal. CONSTITUTION:An Fm signal is inputted to an LPF 1 and only a frequency component at which a low frequency side band causes inversion is outputted. A level of an output of the LPF 1 is adjusted by a variable attenuation circuit 2. A delay correction circuit 3 corrects the processing time delay by the LPF 1 and the circuit 2. A differential input limiter 4 subtracts an attenuated output signal from the variable attenuation circuit 2 from the FM signal corrected by the delay correction circuit 3. The subtraction output is counted by a pulse counter circuit 5 and a demodulation output is obtained. Thus, a high frequency component of the FM signal is not emphasized in the case of a conventional video signal. Thus, noise is not increased, the inversion is prevented and the circuit configuration is simplified.
