Title: Multilayer ceramic wiring board and manufacture thereof
Inventor: SHIMADA YUZO
IPC: H01L23/52
Filed: 1987-07-31
Abstract: PURPOSE:To obtain a multilayer ceramic wiring board whose wiring parts can be transferred into a superconducting state at the temperature higher than the temperature of liquid nitrogen by a method wherein the wiring parts in the multilayer ceramic wiring board are made of material whose main component is samarium-barium-copper oxide. CONSTITUTION:Wiring parts in a multilayer ceramic wiring board are made of material whose main component is samarium-bariumcopper oxide and the wiring parts are formed inside insulating ceramics. As the insulating ceramic material, mixture of quartz glass powder and boron silicate glass powder is employed. A green sheet with a small and uniform thickness is made of the insulating ceramic material and a required conductor pattern is formed on the green sheet with conductive paste. The conductive paste is obtained by kneading samarium oxide (Sm2O3), barium carbonate (BaCO3) and copper oxide (CuO) with organic solvents. Then the insulator and the conductor are baked together. The wiring formed like this is transferred into a superconducting state at about 90K which is higher than the temperature of liquid nitrogen and shows zero electric resistance.

Title: Auto free wheel hub
Inventor: ONODERA TAKAYOSHI
IPC: F16D51/00
Filed: 1983-10-14
Abstract: PURPOSE:To improve the durability of a brake band and reduce drag torque in a wheel hub for a four-wheel driving car by operating a brake shoe that engages, in hole-protrusion shape, with almost a C-shaped plate spring using its expansion and contraction. CONSTITUTION:Brake shoes 22B are engaged with a almost C-shaped plate spring 22A with pawls 22a1 which are bent inward at the both ends thereof while protrusions 22b are engaged with holes 22a2 perforated in the plate spring 22A. Thus, the brake shoes 22B are contacted with or separated from the inner surface of the brake drum 20 according to the expansion and contraction of the plate spring 22A. In such structure, since there is no brake shoe mounting hole in the intermediate section of the plate spring 22A, stress concentration can be prevented and durability can be improved even when the plate spring is contracted by the engagement of a slide ring protrusion 18a with the pawl 22a1. Besides, since the brake shoe B with which the protrusion 18a engages is separated fully from the drum 20, drag torque can be reduced.

Title: Transmitter-receiver
Inventor: YAMASHITA TOSHIHARU
IPC: H04N7/167
Filed: 1993-07-07
Abstract: PURPOSE:To automatically correct an H sag generated in the case of transmission/reception. CONSTITUTION:When a video signal subject to scrambling is transmitted, a reference signal of a predetermined level is inserted into the video signal for a vertical blanking period. A reference signal detection circuit 2 at a reception side detects the reference signal from the received video signal and a subtractor circuit 4 subtracts the detected reference signal from the video signal. The result of subtraction is descrambled. Thus, even when an H sag takes place in the video signal, it is automatically corrected and picture quality is not deteriorated.

Abstract: PURPOSE:To facilitate the maintenance by performing dispersion from the article with the highest use frequency to the memory in a POS register terminal, the PLU memory in a controller, and the disk in the controller. CONSTITUTION:When maintenance is performed for each piece of PLU (price look-up) information, change and deletion data as to object articles of a file 200 for disk PLU, addition, change, and deletion data as to object articles of a file 600 for global PLU, and change and deletion data for object articles of a local file 800 are handled. Then the PLU of each POS register terminal 700 refers to the PLU memory 800 in a POS register terminal 700 as 1st PLU. This 1st PLU is for an article group which is sold most frequently. Consequently, hierachical PLU information is also maintained into the best, up-to-date state at all times by automatic update by setting conditions with parameters.

Title: Plastic optical fiber
Inventor: YAMAMOTO TAKASHI
IPC: C08F20/00
Filed: 1988-08-04
Abstract: PURPOSE:To decrease the light transmission loss by heating zone colors by using a polymer formed by polymn. of a methyl methacrylate monomer in the non-presence of a mercaptan chain transfer agent as a fiber component polymer. CONSTITUTION:A radical polymn. initiator is used and the mercaptan chain transfer agent is not used in combination at the time of producing the polymer essentially consisting of the methyl methacrylate. The polymn. initiator which decomposes actively at the reaction temp. and generates radicals is preferable as the radical polymn. initiator to be used and the polymn. is executed particularly preferably in the presence of an inert solvent. The difficult point with the plastic optical fiber that the fiber exhibits color formation and degrades its light transmission characteristic when exposed under heating is eliminated in this way.

Title: Uneven shape detector
Inventor: NIIZAKI TAKU
IPC: G06K9/00
Filed: 1990-07-20
Abstract: PURPOSE:To reduce assembly error by emitting fully reflected scattered beams to the outside of a transparent light transmission body, forming a spherical face or a non-spherical image formation mirror, where the image is formed, on one part of the transparent light transmission body and arranging an image sensor at a position where the image is formed by the image formation mirror. CONSTITUTION:A spherical mirror is formed by deposition, etc., while being spherically shaped on one end face of a transparent light transmission body 20, and an image sensor 4 is arranged at the image forming position of the spherical mirror 8. When an uneven object 10 gets contact with one face of the transparent light transmission body 20, scattered beams 11 generated from projecting parts P as the result of lighting a contact face S are propagated in the transparent light transmission body 20 while being fully reflected. The scattered beams 11 fully reflected from the projecting parts P are emitted to the outside of the transparent light transmission body 20 by the spherical mirror 8 and image-formed on the image sensor 4 and therefore, the uneven pattern image of the uneven object 10 is converted to a picture data. Thus, since the spherical mirror 8 is formed on one face of the transparent light transmission body 20, an optical system is integrally formed and assembly error is reduced.

IPC: B65B63/02
Filed: 1993-08-05
Abstract: PURPOSE:To improve compression efficiency and downsize an empty bag handling apparatus by constituting the apparatus of a compression plate and a push-in plate for allowing a plurality of flat empty bags which have been compressed and laminated on a bottom wall of a casing to pass through a push-out port while they can be two-folded into a V-shape. CONSTITUTION:Empty bags B put into a casing 23 via an empty bag inlet port 42 provided on a front wall are sequentially compressed flatly by a compression plate 25 which vertically reciprocates, and laminated on a bottom wall 43 of the casing 23. When a plurality of empty bags B are compressed flatly and laminated on the bottom wall of the casing 23, a push-in plate 26 vertically lowers to press a center of the plurality of laminated empty bags to push them into an empty bag push-out port 44 while having the empty bags two-folded into an approximate V-shape at a time. The bags are pushed and received in a collecting bag 30 held below the push-in port in a two-fold state by the push-in plate 26 which further lowers in the empty bag push-out port 44. Since the plurality of empty bags are compressed flatly and further two-folded into an approximate V-shape, an outer diameter of the collecting bag is reduced and subsequent handling is easy.

Title: Toroidal type continuously variable transmission
Inventor: IMANISHI TAKASHI
IPC: F16H15/38
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To realize a construction having sufficient durability without increasing the manufacturing cost in particular. SOLUTION: A roller 36 constituting a roller bearing 32 supporting a disc 4 on the output side is arranged so as to be put to the pressing device 8 side from the center of an inner race track 37. The distance LB between the rear end edge of the rolling face of the roller 36 and the rear end edge of the inner race track 37 is made larger than the lift quantity H of a cam plate 9. Even when the rear half part 15b of a rotary shaft 15 on the input side is displaced at maximum, the rolling face of the roller 36 is not detached from the inner race track 37. Hereby, an edge load is not applied on the rolling face, and hence durability of the rolling face can be insured.
