Title: Document conveyor, document reader and document reading method
Inventor: SHIDA TOSHIO
IPC: B65H29/58
Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To remarkably improve the reliability of preprocessing conducted before reading and to prevent an erroneous action by providing a first inversion section overturning a document on the upstream side of a reading position, and providing a second inversion section overturning the document on the downstream side of the reading position. SOLUTION: A document is conveyed to a platen roller 19 forming a reading position from a conveyance path P3, and the reading position is formed at the lower end of the platen roller 19. The document having passed through the reading position is conveyed to an inversion path P5 through a conveyance path P4 by a conveyance roller 20. A switching guide member 25 guides the document upward along the conveyance path P4, and nearly triangular switching guide members 23, 26 guide the document downward along the inversion path P5. The document is conveyed to the inversion path P5 extending below a read section B by an inversion roller 22. When a sensor S5 detects the transit of the rear end of the document, the inversion roller 22 is stopped, then it is reversely rotated to convey the document upward.

Title: Optical pickup feed device
Inventor: AOKI TAKESHI
IPC: G11B7/085
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent the deformation of a leaf spring pressing piece even when impact is applied by forming a bent piece in a leaf spring pressing a pickup feed shaft in the direction of a shaft and regulating displacement operation. SOLUTION: At the time of feed operation of an optical pickup in the direction of a radius, a pickup feed shaft 2 is energized by an energizing force of a pressing piece 4A in the direction of an arrow mark A, play does not occur in the pickup feed shaft 2. Also, a bent piece 4B in a regulating groove 2C, it is not contacted with the pickup feed shaft 2, therefore, that is not affected by shaft rotation. When external impact is applied to a disk player, the pickup feed shaft 2 resists to energizing force of the pressing piece 4A and it is displaced to in the direction of an arrow mark B, the bent piece 4B is abutted on a side wall 2D of a regulated groove 2C, and displacement in the direction of an arrow mark B is obstructed. Therefore, displacement in the direction of an arrow mark B is prevented and deformation of the pressing piece 4A can be prevented.

Title: Manufacture of semiconductor device
Inventor: KIMURA SABURO
IPC: H01L29/861
Filed: 1989-12-29
Abstract: PURPOSE:To contrive to uniformize a thermal diffusion of a lifetime killer material in the whole wafer by a method wherein a thin film consisting of the lifetime killer material is formed on the whole rear, on which a stopper thin film for shielding the thermal diffusion of the material is formed, of the wafer, this wafer is heat-treated and the material is thermodiffused in the layer. CONSTITUTION:An oxide film 6 is formed on the rear of a thin and discal silicon wafer 1 in a prescribed pattern. An Au deposited film 2 is formed on the whole rear, on which the film 6 is formed, of the wafer 1 by superposing on the film 6 and the wafer is heat-treated in a furnace core tube. By this heat treatment, the wafer 1 is heated at 1000 deg.C or thereabouts, for example, and Au atoms are thermodiffused in the wafer 1 from the film 2. As the film 2 is shielded with the film 6 at the peripheral part of the wafer 1, a thermal diffusion of the Au atoms into the wafer 1 is inhibited. Therefore, though a temperature difference is generated at the time of the heat treatment, the ther mal diffusion of the Au atoms at the peripheral part and central part in the wafer 1 become nearly uniform.

Title: Photoelectric sensor, and paper feeding device using the photoelectric sensor
Inventor: OSUMI YOSHIMASA
IPC: B41J11/42
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To precisely detect a mending tape stuck to a paper in a photoelectric sensor for optically detecting an object to be detected. SOLUTION: A first light receiving element 4 is arranged in a position for receiving the light emitted from a work 3 at an emitting angle larger than the incident angle of the light from a LED 2 on the work 3 which contains no incident surface regulated by the incident direction of the light from LED 2 to the work 3 and the direction vertical to the work 3 surface. According to such a structure, since the distribution of a normal reflected light from a mending tape on the work 3 is caught by the first light receiving element 4, and the light receiving quantity of the light receiving element 4 is largely changed according to the presence and absence of the mending tape, the mending tape can be precisely detected.

IPC: B60C11/16
Filed: 1989-12-28
Abstract: PURPOSE:To simplify projecting or retracting operation by embedding a large number of pin boxes which have been spirally connected to each other with a wire and in each of which a bent pin connected to the wire is housed, in the ground surface of a tire, and by operating the pins via the wire by means of a motor with a driving mechanism which has been arranged in the recessed part of the tire wheel so as to be projected or retracted. CONSTITUTION:A wire-pulling-arm guide shaft 17 is turned in the normal or reverse direction via a gear mechanism by the normal or reverse rotation of a motor 17. Thereby a wire-pulling-arm 15 is moved right and left to pull a wire 4 in the arrow direction or in the reverse direction, so that pins 1 are projected or retracted by the action of pin-guide pieces 3. On the other hand, since the pin-boxes 2 in which these pins 1 and pin-guide pieces 3 are housed are spirally connected by the wire 4, all the pins 1 are linkedly projected or retracted for performing or extinguishing spike function. By this constitution, projecting or retracting operation of pins can be simplified.

Title: Selecting/totalizing method
Inventor: OTA TOKUJI
IPC: G06Q50/00
Filed: 1993-12-22
Abstract: PURPOSE:To ensure the accurate and satisfactory reflection of the selector's will by writing the strength of selection will to the choices on a selection form as the priority and then adopting the choices in the same number as that of selected ones based on the total priority value. CONSTITUTION:The choices selected by a selector are totalized and then the choices are adopted in the same number as that of selected ones. In such a method, the form type inputted through a reading device 24 is recognized by a recognizing device 25 and stored in a storage 27. Meanwhile the strength of selector's will (priority) is written in the due column of a selection form as the segment length, for example. Thus an information processor 29 delets the form type out of all information on the selection form and extracts only the priority. Then the processor 29 totalizes the priority for each selected choice and adopts the choices in the same number as that of selected ones based on the value of priority totalization. Therefore the wills of all selectors are faithfully reflected on the result of totalization of priority for each selector and the reliability is improved.
