Abstract: PURPOSE: To determine the spatial position of the edge part of an optical waveguide easily by examining the position of a light spot formed on the surface of a detector due to light beams emitted from a waveguide for a nominal position. CONSTITUTION: Light passes through a waveguide 1, is emitted, as beams 11, from the end face of a plug pin 2 or the waveguide 1, and is divided into straight-advance and deflection sub-beams 13 and 14 by a beam splitter 12. When the position of the waveguide 1 matches that of a nominal light axis 4, the beams 13 are extended along the axis 4 and the beams 14 are extended along a nominal deflection axis 15. Electrical output signals for forming photo detectors 16 and 17 have information regarding the actual positions of collision points 18 and 19 of the beams 13 and 14 on the photosensitive surface of the photodetectors 16 and 17 for centers 20 and 21 being specified at the axes 4 and 15 and are added to a processor 24 through lines 22 and 23 and heat- application signals are added to manipulators 5 and 6 via lines 25 and 26.

Title: Thin type air cell
Inventor: OE YASUSHI
IPC: H01M4/96
Filed: 1986-11-20
Abstract: PURPOSE:To make a cell small in thickness by forming a minutely porous conductive film as a water-repellent film used at a positive pole and besides making this film function as a positive pole collector. CONSTITUTION:For example, graphite 30wt%, acetylene black 12wt%, polytetrafluoroethylene dispersion 18wt%, and cobalt phthalocyanine 40wt% are mixed without the use of a water-repellent film, and a stainless steel mesh of nickel plating is pressed/filled with this mixture so as to be formed into a positive pole catalyst 5.

Title: Copying machine
Inventor: KAWABUCHI YOICHI
IPC: G03G15/01
Filed: 1987-11-02
Abstract: PURPOSE:To prevent an operator from making mistakes in copying caused by the alteration of the color of a developing device by inhibiting an input from a developing device selecting means even in the developing device selecting means is operated at the time of selecting a simultaneously multicolor copying mode. CONSTITUTION:While the simultaneous multicolor copying is performed by a simultaneous multicolor copying control means after selecting the simultaneous multicolor copying mode by a simultaneously multicolor copying selecting means 97, the input from the developing device selecting means 95 is inhibited even if the developing device selecting means 95 is operated. Therefore, the selection of the developing device is not performed in the simultaneous multicolor copying mode and also the selection of the developing device by the operation of the developing device selecting means 95 is not performed in the simultaneous multicolor copying mode even after the simultaneous multicolor copying mode is released. Thus, it can be prevented that the developing device selected before the selection of the simultaneous multicolor copying mode is different from the one selected after the selection of said mode and miscopying does not occur.

Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a band assignment method and system that can increase number of contained call units in a path switching system where a data loss can be prevented on the occurrence of hand-over. SOLUTION: A band assignment of a hand-over call band is requested in two stages consisting of a required minimum band and remaining bands, respective queues are queued by an FIFO form to accept the request. Thus, the reservation of a useless band can be decreased. Furthermore, the request is accepted at a weight ratio set in advance or at a ratio of number of requests with respect to idle bands from queues queuing the assignment requests of new call bands, hand-over call bands (required minimum) and hand-over call bands (remaining). Thus, the assignment control in response to a change in a system status can be conducted.

Title: Device for clearing sub-code displaying image plane
Inventor: OOYAMA MASAO
IPC: G11B7/00
Filed: 1984-12-27
Abstract: PURPOSE:To process an image plane clear operation at high speed by writing a prescribed clear data in the specific address of a memory element for an image. CONSTITUTION:While the same data for clearing an image plane is written in a video RAM109 as the memory element for the image, the data of an already written specific address area is read every time and a whole displaying area is instantaneously painted out equally so as to previously clear the image plane. After completing the writing to a remaining address area, the data for clearing the image plane is read to display the image plane. Thereby, a time required until a displaying image plane is brought to a substantially complete clear operation can be drastically shortened and the high speed processing of the clear operation can be executed. Since a previous image is not cleared while remaining a part thereof, the image is prevented from the flickering.

Title: Heat exchanger
Inventor: INOUE HITOSHI
IPC: F28D15/02
Filed: 1985-12-10
Abstract: PURPOSE:To eliminate pulsating temperature variation in the oil temperature by submerging the heat absorption section of a heat pipe into the oil in a second flow passage section and arranging the heat radiation section outside the oil tank. CONSTITUTION:High temperature oil that has flowed into a first flow passage of an oil tank 20 flows into a second flow passage, and passes through the heat absorption section 26a of a heat pipe 26 to heat the heat absorption section 26a. At this time a working liquid 27 is also heated. The working liquid 27 robs heat of the oil and evaporates, moving in the heat pipe 26 to the side of the heat radiation section 26b. The steam of the working liquid 27 which has moved is cooled by the surrounding air and condenses but at the same time discharges condensation latent heat and radiates the heat of oil. The working liquid 27 that has condensed and liquefied moves in the heat pipe 26 to return to the side of the heat absorption section 26a. With this arrangement the heat of the high temperature oil 1 passing through the absorption section 26a of the heat pipe 26 is transported from the heat absorption section 26a to the heat radiation section 26b of the heat pipe 26 and radiates heat to the surrounding air by the repeated evaporation and liquefaction of the working liquid 27 in the heat pipe 26.
