Title: Air conditioner
Inventor: FUTAGAMI EIJI
IPC: F25B13/00
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To efficiently control the flow of refrigerant by using a tube with a groove, as a piping, between the delivery side of a compressor and an outdoor heat exchanger and between the compressor and an indoor heat exchanger to restrain a turbulent flow of refrigerant. SOLUTION: In a refrigerant circuit of the air conditioner, a compressor 1, four-way valve 2, outdoor heat exchanger 3, pressure reducing device 4, and indoor heat exchanger 5 are successively connected by pipes 6a, 6b having different diameters. In this case, pipes 6a, 6b between the delivery side of the compressor 1 and the exchanger 3 and between the compressor 1 and the exchanger 5, where a turbulent flow tends to occur in the refrigerant which circulates in a cooling or heating operation, are formed from a pipe 1 having therein a plurality of grooves 7a in the same direction as the flow of refrigerant, and pipes 6a between the exchanger 3 and the device 4 and between the device 4 and the exchanger 5, where a turbulent flow tends to occur not so frequently as in the delivery side of the compressor, also are formed from the pipe 7, to restrain a turbulent flow of refrigerant.  And an ordinary pipe is used for a pipe 6b connecting the valve 2 and the compressor 1 since a turbulent flow does not occur in the pipe 6b.

Title: Semiconductor photodetector
Inventor: SUGIYAMA MITSUHIRO
IPC: G02B6/42
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To make thin single crystal semiconductor regions, including a light- absorbing layer and raise the light intensity at this light-absorbing layer by sandwiching the upper and lower sides of a first single crystal semiconductor region to be the light-absorbing layer between insulating films through second single crystal semiconductor regions. SOLUTION: A semiconductor photodetector comprises an n-type Si layer 3 on an SOI substrate 1, having an Si oxide film 2 buried in an insulation plate 1a. In a trench 10 at the center of the Si layer 3 a light-absorbing layer 4 and P-type Si layer 5 are grown epitaxially, and the absorptive layer 4 is sandwiched between the oxide film 2 buried in the SOI substrate 1 and Si oxide film 7 covering the photodetector top. This can raise the light intensity of a core, even if a waveguide is made thin, since the refractive index of the Si oxide film is considerably low, compared with that of Si.

Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To make writable default data by a simple operation by writing the default data into a nonvolatile memory when the judged result of the writing end judgement data is not coincident with its expected value. SOLUTION: The reading of data stored in a nonvolatile memory 2 is started, the writing end judgement data are read out and a judging part 5 checks the coincidence between the writing end judgement data and the expected value that is given from a writing end judgement data writing part 4. When the checking result of the part 5 is not coincident with the expected value, it is judged that the writing of the default data into the memory 2 is not coincident yet with the expected value. Then the user setting data given from a default data generation part 6 are successively written into the memory 2. Then, the writing end judgement data are written into a specific address as the expected value. As a result, the default data can be written by a simple operation.

Abstract: PURPOSE:To effectively utilize a space so as to safely carry out a surplus material by discharging each surplus material with the center of gravity aligned to a discharge point set to a suitable position of a remainder yard, in the case of discharging the surplus material to the remainder yard. CONSTITUTION:An encoder 119, serving as a drive control means, is actuated simultaneously by rotating a roller 17 of a material feeder 5, so that in the case of discharging a surplus material Ws to a side of material suppliers 7A, 7b, 7C, a moving distance of the material can be controlled. That is, half of the total length of the surplus material Ws at the center of gravity, a distance between a discharge point P-P line and the position of the center of gravity, when a length of the surplus material Ws is measured, can be calculated, and the surplus material Ws is fed out by that distance. In this way, in all the surplus material Ws, despite its length, the center of gravity is aligned to the discharge point P-P line to arrange the surplus material Ws in a stable condition without obstructing an effective space, and also load collapse is eliminated in the case of discharging a large number of the surplus materials Ws, arranged in a remainder yard 9, bundled to the other place by a wire or the like.

Title: Polarized wave scrambler
Inventor: TERAHARA TAKAFUMI
IPC: H04B10/532
Filed: 1994-10-17
Abstract: PURPOSE: To simplify constitution and to contrive a low price of an optical transmission terminal station by providing both functions of polarized wave scrambling and monitoring control signal superposition in one device. CONSTITUTION: A phase modulator 10 is an optical phase modulator utilizing the electrooptic effect of crystal, and a linearly polarized wave of azimuth angle 45 deg. is inputted to an axis of polarization which supplies an ordinary ray refractive index to input signal light I(1) and to an axis of polarization which supplies an extraordinary ray refractive index to the same. In such a case, since a modulation signal V which drives the modulator 10 functions in an electric field, a driving part 2 can be constituted of an ordinary electronic circuit. Also, since a partial polarizer 3 is an optical element with polarization dependent permeability or polarization dependent reflectivity and is also a partial polarizer, no high polarization extinction ratio is required, the partial polarizer easily be realized.  Further, when a data signal such as a monitoring control signal, etc., is superimposed on the modulation signal V, the intensity modulated light frequency on the output side of the polarizer 3 can be changed by changing its signal frequency depending on a data content, therefore, data can be superimposed on signal light to which the polarized wave scrambling is applied with intensity modulation.

Abstract: PURPOSE:To form a fine gold wiring by etching a film to form side walls on a metal film for wiring, and removing first and second metal films to improve a downwardly tapered shape, thereby preventing extraneous particles from depositing on the side walls of the metal film during a dry etching process. CONSTITUTION:A titanium-tungsten film 3 for an adhesion and barrier layer is deposited on a substrate 1 coated with an insulating film 2. A gold film 4 is deposited by sputtering for protection from a gold plating solution. After a patterned photoresist 5 is applied, a gold film 6 for wiring is formed by selective electroplating. The photoresist 5 is removed, and then a photoresist 7 is applied. The photoresist 7 is etched so that it can remain only at side walls of the film 6 by anisotropic dry etching with a gas that has no effect on the gold film 4. The gold film and the titanium-tungsten film are etched to remove the photoresist 7 so that a gold wiring is formed.

Title: Cooler for pressurized water reactor
Inventor: YOKOMURA TAKENORI
IPC: G21C15/18
Filed: 1988-10-06
Abstract: PURPOSE:To stably maintain a cooling stage over a long period of time by storing a reactor vessel into the water in a container in which water is filled and providing a decay heat cooler having an automatically operating valve to this reactor vessel. CONSTITUTION:The automatically operating valve 29 of the decay heat cooler 22 is automatically opened by the pressure increase in the container or the pressure fluctuation or temp. fluctuation of the primary system when a rupture accident arises at the reactor vessel 2. The endothermic part 20 of the cooler 22 is positioned in the high-temp. part in the upper part of the reactor core 4 and the heat radiating part 21 thereof is positioned in water 19 which is a low-temp. part at this time; therefore, natural circulation (convection) arises in the inside water when the valve 29 is opened. The decay heat received in the endothermic part 20 is continuously radiated continuously into the water 19 in the heat radiating part 21. The water in the cooler 22 is stably circulated without boiling the water if the pressure in the endothermic part 20 of the cooler 22 is previously set high. The stable cooling state is thus maintained for the substantial time after the occurrence of the accident.
