Title: Manufacture of superconducting wire
Inventor: SUGIMOTO MASARU
IPC: H01B13/00
Filed: 1987-07-07
Abstract: PURPOSE:To make it possible to manufacture a homogeneous superconducting wire having excellent characteristic by melting a superconducting material in a crucible, blowing it to a rotating roll and making it into the shape of a tape by rapid cooling, and heat-treating it to give superconductivity. CONSTITUTION:A raw material 4 constituting a superconductor is put into a crucible 1, heated and melted by induction heating coil to become a molten material 4Y. While rotating a roll 3 at a high speed, the molten material 4Y is continuously blown out of a nozzle 1A onto the outer circumferential surface of the roll 3 and quenched to obtain a long-sized tape material 5. The tape 5 is heat-treated in an oxygen flow to oxidize and form a superconducting wire. This causes the material to mix uniformly and prevents microscopic segregation at the time of quenching. Further, oxygen atoms are prevented from being removed from the superconductor at the time of the heat treatment, making it possible to manufacture the superconducting wire of homogeneous composition and of excellent superconductivity.

Title: Variable reactance circuit
Inventor: TANAKA KANJI
IPC: H03H11/48
Filed: 1982-09-27
Abstract: PURPOSE:To change an equivalent reactance over a wide range from a negative to a positive specified value, by combining two amplifier circuits operated respectively as a positive and a negative equivalent reactance. CONSTITUTION:An output of an amplifier 1 operated as the positive equivalent reactance and an output of an amplifier 2 acting like a negative equivalent are connected respectively to an output terminal 3 in common.

Abstract: PURPOSE:To prevent plate glass from deteriorating due to scratches, in the device used in an in-horizontal-furnace press system by providing a temporary forming means and a blow bending means for the plate glass respectively to a common bending surface and a deep bending surface of mold. CONSTITUTION:A sheet of plain plate glass 1 is transferred to a bending treatment stage by a conveyer 3, and, after positioning, a mold 10 is descended to the position of glass 1. Then, a lift jet device 21 working as the temporary forming device 20, and sucking device 25 are put in action, and the mold 10 is ascended thereafter. When the temporary forming device 20 put in action, the central part of the glass 1 is attracted and held by the common curved surface 15a of the mold 10 and temporarily formed, but the side of the glass 1 are not attracted to be sucked to deeply bent curved surfaces 15b as the blowing-up force and suction force are not enough there. Therefore, the blow bending device 30 is put into operation thereafter to blow air against the side parts of the glass 1 from nozzle 34 provided to the position confronting the curved surface 5b. Thus, the bend forming process for the glass 1 is temporarily finished.

Abstract: PURPOSE:To adjust the inclination before meandering of the strip by setting the sensors at both right and left ends of the carriage, detecting and calculating the inclination of the carriage and its change with the lapse of time. CONSTITUTION:The sensors 2 are set at both right and lift ends of the carriage 1 and at both fixed parts 3 opposite to the above so as so sense with right and left at the same time if the carriage 1 is in the horizontal state. When the carriage 1 is moved up and down as it is in this state, the both right and left sensors 2 sense at the same time. If the carriage 1 elevates or lowers in the inclined state caused on the generation of the stretch of the wire rope 6 hanging the carriage 1, etc., the difference ( t) of the sensing time is generated at the both right and left sensors. By detecting this deference of sensing time, the inclination of the carriage 1 can be known. And the inclined quantity ( h) is obtd. by multiplying the speed (v2) of elevating/lowering of the carriage 1 by the difference ( t) of detected time, i.e., it can be calculated as  h=v2X t.

Abstract: PURPOSE:To eliminate the contamination of a rod array lens due to a sealing resin by fixing the rod array lens to a case body by the engagement of the cover member made of a transparent material covering the rod array lens with the case body. CONSTITUTION:When a cover member 20 is fitted to a case body 11 so that the respective engaging pieces 21 of the cover member 20 pass through the passage of the case body 11 and subsequently slide in a longitudinal direction, the respective engaging pieces 21 come into contact with the inclined engaging surface 24 of the second engaging part 23 of the case body 11 to fix the cover member 20 to the case body 11 and, by this fixing, the inner bottom surface 26a of the long groove 26 of the cover member 20 comes into close contact with the leading end surface of a rod array lens 15 to downwardly press the rod array lens 15. As a result, the rod array lens 15 can be fixed to the slit groove of the case body 11. Since no sealing resin is used, the contamination of the rod array lens with the sealing resin can be eliminated.

Title: Grinding device for work
Inventor: OZAKI HARUO
IPC: B24B57/02
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To stably keep high grindability for a long time by providing a nozzle spouting a high-pressure fluid to an outer peripheral surface of a rubber wheel, and executing the grinding while dressing the rubber wheel with high-pressure fluid, when a work is ground by the rotating rubber wheel including an abrasive. SOLUTION: A rubber wheel 4 is rotated and driven in the direction perpendicular to a surface of a work 6 rotated in a horizontal surface by a spindle to grind an outer peripheral edge part of the work 6. The grinding is executed in a state that the rubber wheel 4 is pressed to the work 6 while supplying the cooling water 23 from a nozzle 24 during the grinding, but the grinding force is gradually impaired because of the adhesion of the abrasive powder 4b to an outer peripheral surface 4a of the rubber wheel 4. By spouting the high-pressure water 5 in the whole width direction perpendicularly to the tangent direction of the outer peripheral surface 4a from the nozzle 2, the abrasive powder 4b is removed from the outer peripheral surface 4a, and a superior grinding state capable of exposing the diamond particles 4c can be kept.

Title: Paper sheet separating device for automatic paper feeder
Inventor: MORINO TAKETSUGU
IPC: B65H3/52
Filed: 1985-07-31
Abstract: PURPOSE:To prevent letters from blurs and a paper sheet from stains even if pencil written manuscripts are inserted, by making a roller rotating in the opposite direction to the feed direction of the paper sheet and a frictional pad contact with a belt. CONSTITUTION:A drawing-out roller 3 bears against the central front edge of stacked paper sheets 2 and rotates to feed out the paper sheet 2 in the direction of the arrow. The fed-out paper sheet 2a is inserted into the contact portion of a belt 8 with a roller 13 and further into the contact portion of the belt 8 with a frictional pad 14. Since the belt 8 comes in contact with the roller 13 and the frictional pad 14 in the tensioned portion of the belt 8, the contact force is small so that the force acting on the inserted paper sheet 2a is small. Thus, while the paper sheet 2a advances in the contact portions of the belt 8 with the roller 13 and the frictional pad 14, the underside paper sheet of the advanced paper sheets 2a engages sequentially the frictional pad 14 so that only the uppermost paper sheet passes through.

IPC: F04C2/18
Filed: 1994-06-30
Abstract: PURPOSE:To reduce the noise level of a pump by using an involute gear where the base circle is larger than the root circle, and the bottom is formed of a single or a plurality of curved or semi-curved surfaces passing through three points, i.e., the intersection of the tooth face of the adjacent gears and the base circle and the centers of the bottom circles therebetween. CONSTITUTION:An involute gear where the base circle 24 is larger than the bottom circle 25 is employed in a driving gear 1 and a driven gear 2. A clearance (space) is set to be small within the range of the regular engagement. In addition, the bottom 26 is formed of a single or a plurality of curved or semi-curved surfaces passing through three points, i.e., the intersections a1, a2 of the tooth surface of the adjacent tooth surfaces and the base circle 24, and the center point a3 of the bottom circle 25 between the intersections a1, a2. Because the amount of water entrapped in a space 27 is reduced, the vibration of the gears 1, 2 caused by the water pressure is reduced, and the noise in the pump which is generated by the collision of the gears 1, 2 or the collision between the gears 1, 2 and shafts 6, 8 is reduced.
