Patent JP-S6022380-A (JP)
Title: Solar cell
Inventor: YAMAMOTO AKIO
IPC: H01L31/06
Filed: 1983-07-18
Abstract: PURPOSE:To upgrade the conversion efficiency of a solar cell by a method wherein the solar cell having a P-N junction or an MIS structure is manufactured using a compound semiconductor substrate with the (111)A plane, which has been formed with pyramidal roughnesses on the surface thereof. CONSTITUTION:A P type InP single crystal with the (111)A plane is used as a substrate 6 and an etching treatment is performed on the substrate 6 with Br (1-2%) methanol solution for forming pyramidal roughnesses on the surface of the substrate 6. An S is performed a thermal diffusion from the rough surface as donor impurities for 3hr at 700 deg.C, and by turning the about 0.3mum deep surface layer into an N type InP layer 7, an InP solar cell having an N-P junction can be obtained. By this method, the improvement of the short-circuit current density, that is, an improvement to 33mA/cm<2> from 30mA/cm<2> obtained by the conventional method, is contrived, and as the result, the conversion efficiency is also greatly improved, rising to 14.5% from 13%, compared with the conventional method.

Title: Relay line selection system
Inventor: YUI TAKAYUKI
IPC: H04M3/22
Filed: 1986-06-03
Abstract: PURPOSE:To improve the efficiency of the titled system without requiring an exclusive processor for relay line selection by sending a line group number and a processor number of a desired path to select a relay line while a processor of the reception side is changed sequentially. CONSTITUTION:When a subscriber connected to a subscriber line (CEN) 00 accesses a path A, a processor (PN) 1 selects a processor PN 2 to the path A from the 1st memory (MA) 100 and the processor PN2 selects lines CEN 10, 11 depending on a received line group number (CG)10. If both the lines CEN 10, 11 are busy or faulty, the processor PN1 receives information from the processor PN2 via a bus 4, increases an address P0 by 1 to send a number CG20 and an address P1 to a processor PN3 of the address P1 via the bus 4. The processor PN 3 uses the 2nd memory (MB) 301 to select lines CEN 20, 21. Thus, no exclusive processor of relay line section is required and so long as a normal processor remains, a decentralized control exchange is not subjected to system-down.

Title: Roller bearing
Inventor: TAKEMURA HIROMICHI
IPC: F16C33/32
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To prevent early exfoliation due to high vibration and high loading and drastically elongate the life by carbonizing or carbonitriding a high carbon chrome bearing steel as a rolling element and specifying a residual austenite quantity on a surface layer. SOLUTION: A high carbon chrome bearing steel is carbonitrided under an atmosphere of Rx gas, enriched gas, and 5% ammonia gas in the temperature 820-870 deg.C for approximately 2-5 hours, then quenched by dipped in oil of 60 deg.C for 30 minutes, and annealed at the temperature 180 deg.C for 2 hours so as to be used as a rolling element 4. The residual austenite quantity on the surface layer of the rolling element 4 is set to 20-45vol%. A damper effect is applied on the surface layer of the rolling element 4, high vibration and high loading transmitted from a turning wheel 3 to a fixed wheel 2 via the rolling element 3 are absorbed on the surface layer, and early exfoliation of the fixed wheel 2 can be prevented. The life of the bearing can be thus drastically elongated despite of the low cost.

Abstract: PURPOSE:To reduce the capacity of a memory in an external equipment and, at the same time, to eliminate the necessity of special processing to extract a specific signal, by providing an extracting means which extracts image signals of an optional color instructed from the external equipment. CONSTITUTION:To a reader which outputs image data obtained by the reader by picking up the image of an object 21 to be read and converting the image into image signals of three colors to the external equipment, an extracting means 32 which extracts image signals of an optional color instructed from the external equipment is installed.

Abstract: PURPOSE:To improve the operability of an image processor by detecting a mark put on an original based on the color characteristic registered in the format information, extracting an image out of the mark, and synthesizing the extracted image based on the format information. CONSTITUTION:A color characteristic learning part 3 starts its processing by a color characteristic learning start signal sent from a mode switching part 2 and learns the color characteristic in accordance with the gradation or one or both of colors of a mark put on a color characteristic learning form. Then the part 3 registers the color characteristic. A format learning part 4 starts its processing by a format learning start signal received from the part 2 and collates the gradation or the color of the mark put on a format learning form with the color characteristic. Then the color characteristic and the position coordinates of the collated mark are registered as the format information used for synthesization of an image. Then an image extracting pat 5 starts its operation by an image extraction start signal received from the part 2 and detects a mark put on an original based on the color characteristic registered in the format information to extract an image out of the mark area. An image synthesizing part 6 synthesizes an image based on the format information. Thus the operability of an image processor is improved.

Filed: 1983-07-19
Abstract: PURPOSE:To prevent yarn from being wound within the range of traverse during the time right after catching the end of a yarn until said yarn is picked up by a traverse guide by providing two yarn receiving guides for carrying out positioning. CONSTITUTION:Before yarn Y is wound around an empty bobbin, it is kept in a separated condition from a traverse guide 8 by means of a push-in rod 19. And, further, the yarn Y is moved out of the range of traverse 40 by means of a rotating lever 23, maintaining a position where it is not engaged with a traverse guide 8, by means of two yarn receiving guides 11, 12. The yarn Y is caught by a yarn catching part. After that, the yarn Y falls sliding down the end side parts 42 of the both yarn receiving guides 11, 12, returning into the range of traverse. Thereby, the winding of the yarn Y within the range of traverse 40 can be eliminated during the time right after catching the end of yarn until it is picked up by the traverse guide 8.

Inventor: KAWAMURA KOUICHI
IPC: G01B7/04
Filed: 1977-11-02
Abstract: PURPOSE: To obtain the slab width distribution of the slab to be rolled immediate before edging rolling by setting the roll spacing where width screw-down is applied over the entire longitudinal direction of the slab material and detecting the actual rolling load distribution in performing edging rolling of the slab material.  
     CONSTITUTION: The longitudinal direction position l of the slab material to be rolled SLAB is detected with a device PG and the rolling load P is measured with a device LC, from which the rolling load distribution is detected with an arithmetic unit CPU. In the first pass of rolling, the spacing of the rolls ER where screw-down is always applied in each position of the longitudinal direction of the slab material is determined and a roll spacing is set in that spacing, then edging rolling pass is performed and the rolling load distribution (rolling load values in the respective positions in the longitudinal directions) is detected. From the predetermined reference rolling load distribution of the slab material to be rolled and the actually measured rolling load distribution, the slab width distribution of the slab material to be rolled immediate before edging rolling is estimated.

Abstract: PURPOSE:To obtain a transfusion pharmaceutical, containing an amino acid and an electrolyte and excellent in stability and safety in sterilization and preservation. CONSTITUTION:The objection transfusion pharmaceutical is obtained by including an amino acid and further calcium and phosphorus as electrolytes and regulating the pH to 5-8 with an organic acid (e.g. citric acid). A polyhydric alcohol or a phosphoric acid ester of saccharides (e.g. glycerophosphoric acid) or salt thereof (e.g. sodium salt) as a supply source of phosphorus is blended and the amino acid concentration is 1-15% (wt./vol.). The resultant transfusion pharmaceutical does not produce precipitates, coloring, etc., even in thermal sterilization and deteriorate other transfusion pharmaceuticals when mixed therewith. Since operation to mix the amino acid with the electrolytes is not required, operation is simplified to prevent the pharmaceutical from being contaminated with microorganisms in mixing.
