Title: Refrigerating system
Inventor: OGAWA KEIJI
IPC: F25B41/06
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To ensure the flow of a refrigerant even when the atmospheric temperature is high by providing an electric valve deformation operation flow-rate control volve between a condenser and an expansion device to interrupt the flow of a refrigerant from the condenser when a compressor is stopped. SOLUTION: During the opening of an electric valve deformation operation flow-rate control valve, with a coil 9 not energized, a valve main body 11 is turned spherical and a refrigerant flows to an outgoing path 8 from an incoming path 7 to maximize the flow thereof. During the closing of the valve, when the energization of the coil 9 is started and causes the valve main body 11 to be deformed oval, the incoming path 7 and the outcoming path 8 are closed to shut out a path to let the refrigerant move in or out to minimize the flow rate thereof. The deformation of the valve main body 11 varies with increase or decrease in the electric energization of the coil 9 to allow the adjusting of the flow rate of the refrigerant.  This enables variable stepless control of the flow rate of the refrigerant associated with changes in the number of revolutions thereby always generating the optimum condition of a refrigerating system.

Title: Locking mechanism
Inventor: PIITAA GURAHAMU DOOSON
IPC: H01R13/629
Filed: 1990-10-12
Abstract: PURPOSE: To facilitate taking-out and inspection of a wire even when an engineer wears thick gloves by connecting a nut and a body with respective counterpart components and pressing and engaging a spring with the components. CONSTITUTION: A nut 13 and a body 18 are connected with respective counterpart components 36, 37 in a ratchet mechanism.

IPC: G01B11/00
Filed: 1986-11-17
Abstract: PURPOSE:To perform quantization for obtaining contrast information effective for the measurement of a distance, by quantizing a photocurrent on the basis of the smaller value of the max. values of the photocurrents in two respective light receiving element rows. CONSTITUTION:The reflected light from a body 53 to be subjected to the measurement of a distance is received by the first and second light receiving lenses 54, 55 through light paths different from each other and images to be subjected to the measurement of a distance are formed on predetermined focal surfaces. The photocurrents of the light receiving elements respectively arranged in the predetermined numbers corresponding to the number of said images in the first and second light receiving element rows 56, 57 are quantized by quantizing means. From the relative relation of the outputs of the quantizing means to the respective element rows 56, 57, the distance up to the body 53 to be subjected to the measurement of a distance is measured. At this time, since quantization is performed on the basis of the smaller value among the max. values of the photocurrents in two element rows 56, 57, even when there is a part extremely strong in light receiving intensity only in the single element row, it is prevented that quantization different in a level is performed by two element rows 56, 57 or necessary contrast information is erased.

Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a recorder in which a thermal head can be protected against damage or shortening of service life by preventing temperature rise of the thermal head more than required. SOLUTION: When the temperature of a thermal head is between 60 deg.C and 70 deg.C (S12: No), steps S13-S21 are executed repeatedly and protective recording is performed with single color of black.

Patent JP-H1198683-A (JP)
Title: Load current controller
Inventor: UCHIDA KEIJI
IPC: H02H9/02
Filed: 1997-09-20
Abstract: PROBLEM TO BE SOLVED: To control load current so as to be within a prescribed value, by forming a load current discrimination mechanism for constantly discriminating whether or not load current exceeds a prescribed value at the time of power input. SOLUTION: In a heater equipped with a controller, for example, a computer 3 is connected to the output of a current detector 2, load current can be always grasped, and the firing angle of a TRIAC 1 is controlled so as to be within limit current. When the temperature of a load (PTC heater) 5 rises with time and current decreases, the computer 3 detects it, increases the firing angle of the TRIAC 1 gradually, and increases current to the limit value to control it for efficient heating. After the time passes and the temperature of the load 5 reaches around 20 degrees, the current is lower than the limit value with the firing angle of the TRIAC 1 made full firing, and a TRIAC current itself is short-circuited with a relay 4. The load current passes through the relay 4, not through the TRIAC 1, thus it is possible to prevent generation of heat at the TRIAC 1.

IPC: G03B17/42
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To provide a shutter charge mechanism preventing an image from being photographed in an exposure inhibition area used in developing processing. SOLUTION: After photographing for all frames for photographic film 22 is finished, the film is wound, and when the meshing of a driven sprocket 54 and the film 22 is released, a projection 70 on the lower surface of an exposed frame number display board 46 which is turned abuts on the leading piece 49e of a locking lever 49. Thus, the display board 46 is prevented from being turned after that, and also a rotating member 51 meshed with the display board 46 and the driven sprocket 54 coaxial with the member 51 are prevented from being turned, so that film winding stop and shutter charge are not carried out. Therefore, photographing is not performed in the exposure inhibition area arranged at the trailing edge of the film 22.

Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To avoid self-doping by etching a Si substrate by a specified thickness with a silicon chloride compound gas introduced before depositing in the vapor phase epitaxial deposition on the Si substrate having high-concentration dopant regions. SOLUTION: In the vapor phase epitaxial deposition on a Si substrate 1 having dopant regions 6, 7 containing boron at a high concentration, the initial annealing is selectively made and the epitaxial deposition is made for a given time to obtain an epitaxial layer 5 having a desired usual thickness. Before the epitaxial deposition, a silicon chloride compound gas is introduced to etch the Si substrate 1 by a thickness of about 100 nm or less to thereby remove a self-doped layer of boron to the epitaxial layer 5. Thus the self-doping of boron to the epitaxial layer 5 is reduced.
