Title: Measuring device for microwave radiometer receiver
Inventor: HIGUCHI MASAYUKI
IPC: H04B17/00
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To provide a measuring device for a microwave radiometer receiver having high measuring accuracy by covering a receiver and a waveguide or a coaxial cable with nitrogen gas so as to facilitate estimation of an input noise temperature. SOLUTION: A receiver 1, a waveguide or a coaxial cable 2, a terminal 3 and a liquid nitrogen Dewar vessel 4 are covered with a nitrogen sealer 6 and nitrogen gas is injected by a nitrogen cylinder 7. Then, air is eliminated from the sealer 6 and water vapor is also eliminated. Thus, the waveguide or the cable 2 is prevented from being frozen or frost sticking is prevented and fluctuations in the temperature T of the waveguide or the cable 2 and in an electical loss L are reduced. Thus, since an input noise temperature is accurately estimated, a measuring error is reduced and measuring accuracy is improved. Further, for the receiver 1, freezing or frost sticking is prevented.

Title: Semiconductor photodetector
Inventor: ISHIMURA EITARO
IPC: H01L29/205
Filed: 1987-11-16
Abstract: PURPOSE:To obtain a ultra-high speed semiconductor photodetector using the Aharonov-Bohm effect by forming a current path composed of a semiconductor having high purity and having thickness of approximately a de Broglie wavelength, semiconductor regions partially dividing said path and having different impurity concentration or consisting of different materials and a light-receiving surface to make light incident near the semiconductor regions. CONSTITUTION:When light having a wavelength absorbed by GaAs is projected from a light-receiving surface 9 through an antireflection film 10, carriers are generated in a GaAs line 2, but more carriers are generated with approach to the light-receiving surface 9. The difference of potential is generated in GaAs on the upper side 2a and lower side 2b of AlGaAs 4 by the concentration difference of the carriers. Since phase difference is generated by electron waves passing through the upper side 2a and lower side 2b of AlGaAs 4 by the difference of the potential and electron waves interfer, electron waves flowing between a gate and a source change. Accordingly, the element can be used as a photo-detector because a current value between the gate and the source changes by the amount of incident light.

Abstract: PURPOSE:To attain a smaller power, miniaturization and a lower cost minimize power by providing a plurality of taps on the primary side coil of the transformer of a starting circuit, and operating a tap switching circuit to generate a starting voltage and a lighting keeping voltage, respectively. CONSTITUTION:By inputting a signal from a signal input terminal (a) after inputting a power source from a power source terminal (c), transistors Q3, Q4 are alternately ON/OF and laid in oscillating states, and a discharge starting voltage is applied to a fluorescent lamp 5.

Abstract: PURPOSE:To take out a laser beam characterized by high efficiency and good quality in a discharge tube having a large diameter, by resonating the gain at a part other than a low-order-mode exciting part by by total reflecting surface of an aperture together with a total reflecting mirror, and effectively utilizing the resonation. CONSTITUTION:An aperture 37 is arranged at the inside of a resonator of a partial reflecting mirror 20. A laser beam other than that at a laser taking-out part is totally reflected, and a resonating state is formed together with a total reflecting mirror 19. When a high voltage is supplied from a power source 18, glow discharge is generated between an anode 22 and cathode 26, and a laser medium in the discharge tube 1 is excited. The laser beam is taken out of the laser taking-out part of reflecting mirror 20.

Title: Sensitive material processing device
Inventor: MIYASAKA EIJI
IPC: G03D3/00
Filed: 1990-10-25
Abstract: PURPOSE:To accomplish a sensitive material processing device which is maintenance- free and facilitate management of the temp. of processing liquid by forming a processing trough for storing the processing liquid with such a length as admitting immersion of sensitive material only partially, and thereby lessening the stored quantity of processing liquid. CONSTITUTION:A sensitive material PM after exposure is fed from a roller couple 92 to intrude into a storage part 95, and during passage through it, the material reacts with the stored developing solution to commence the developing process. After passage of the storage part 95, the material moves on the oversurface of an inclined guide plate 110 and is sent to a throttle roller couple 109 installed at the inlet to a stabilizer part 72. Because a specified temp. is prepared on the guide plate 110, development of the sensitive material PM is continued by the attached developing solution even during transportation. The sensitive material PM sent from the development part 70 gets rid of attached solution by the roller couple 109 and is transported to storage part 95A, and in a stabilizing agent, the stabilization process is started. After passage of this part, stabilization process will proceeds even during the period of being transported on the oversurface of a guide plate 110A. Surplus stabilizing agent is squeezed off during passage of a throttle roller couple 109A, and thereafter the material is sent to a drying unit 50 by a roller couple 51.

Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To flatten the surface of a filler filling up trenches not only at the straight sections of the trenches, but also at the crossing section of the trenches, by providing an island-like part surrounded by the trenches at the crossing section of the trenches and filling up the trenches with the filler. SOLUTION: After a silicon oxide layer 2 is formed on the upper surface of a silicon substrate 1, a polycrystalline silicon layer 3 is formed on the layer 2 by the low-pressure CVD method. Then, a silicon nitride layer 4 and a photoresist layer are successively formed on the layer 3 and an opening is formed, so that the opening can surround an island-like part 4a by removing the silicon nitride layer 4 by performing wet etching by using the photoresist layer as a mask. After the opening is formed, a silicon oxide layer 2c is formed on the side walls of the trenches 9 formed of the opening and a polysilicon layer 10 is formed by the low-pressure CVD method as the filler of the trenches 9. Therefore, the occurrence of disconnection, etc., in a wiring pattern can be prevented, because the surface of the filler at the crossing section of the trenches 9 can be flattened.

Title: Pulse position detector
Inventor: HIRAI TOSHIYUKI
IPC: G01S7/292
Filed: 1988-11-17
Abstract: PURPOSE:To reduce an integration circuit to one and to prevent the integration circuit from being affected by offset voltage drift by subtracting the double output of the integration circuit that is the intermediate result of the output of the integration circuit from the final result of the output of the integration circuit. CONSTITUTION:The output of a sample and hold circuit 4 is equal to an area where an input signal is segmented from the front end of a gate G 1 to the center of the gate, and the output of the integration circuit 3 is equal to the area where the input signal is segmented from the front end of the gate G 1 to the rear end of it. Therefore, the output of the integration circuit 3 goes to double the output of the sample and hold circuit 4 when the center of the input signal X0 is equal to that of the gate. Thereby, the output of the sample and hold circuit 4 is doubled by a scaler 6, and the output of the integration circuit 3 is subtracted at a subtractor 7. In such a way, a signal with amplitude proportional to the difference of the center of the input pulse signal X0 and that of the gate is outputted from the subtractor 7.
