Title: Electronic part and manufacture thereof
Inventor: YASUDA KATSUHARU
IPC: H01F41/04
Filed: 1990-07-31
Abstract: PURPOSE:To obtain an electronic part having small eddy current loss, low loss, low heat generation, high efficiency and excellent magnetic characteristics by a method wherein, in an electronic part in which a coil is embedded in a coil-supporting body, the supporting body is composed of a plurality of magnetic parts, arranged leaving a space between them, and an insulating part. CONSTITUTION:A coil supporting member 2 is composed of a plurality of magnetic parts 21 arranged leaving an interval between them, and insulating parts 22. Each of the magnetic parts 21 constitutes the magnetic path for the magnetic flux formed by a coil current, and the insulating parts 22 are arranged in such a manner that the intervals between the magnetic parts 21 and 21 are buried. The magnetic flux phi1 formed by the coil current moves toward the direction of coil spool O1, and an eddy current Ie is going to be generated around the coil spool O1. As the insulating parts 22 are located in the direction of the above-mentioned eddy current Ie, the eddy current Ie is broken by the insulating parts 22, and no eddy current Ie is allowed to flow between the magnetic parts 21 and 21. As a result, the loss of the eddy current is small, and an electronic part of low loss, low heat generation and high efficiency can be obtained.

Title: Coil transfer method
Inventor: SUZUKI MEGUMI
IPC: B21C47/24
Filed: 1991-07-23
Abstract: PURPOSE:To provide a coil transfer method for reliable grasping of the center of a coil being conveyed on a conveyer, and for safe and reliable transfer of the coil from the conveyer to a down ender. CONSTITUTION:Two photoelectrical sensors PH2 and PH3 which form a predetermined angle and a photoelectrical sensor PH1 which lies at right angles to the center line of a conveyer 2 are arranged. The diameter of a coil 1 being conveyed and the deviation of the center line of the conveyer from the center line of the coil are measured at the first reference position using the PH2 and PH3. Then it is detected by the PH1 that the outer diameter of the coil 1 has reached the first reference position to calculate the distance up to the second reference position of a coil transfer device. Based on the calculated distance, coil transfer is stopped when the center of the coil has reached the second reference position. This makes it possible to transfer the coil to a down ender safely and reliably, and to promotes improvement of maintainability and automation of operation.

Title: Image recorder
Inventor: TAKEDA MORIYASU
IPC: G03G13/26
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To provide an image recorder capable of stably feeding photosensitive material by always applying fixed tension to the photosensitive material. SOLUTION: If load fluctuation is caused in the case of pulling out the photosensitive material 2 from a magazine 1, it influences a pair of introducing rollers 3 and the carrying amount of the material 2 by the pair of rollers 3 is changed. In such a case, if a main driving roller 8 continues stable carrying, the up-and- down position of a tension roller 21 is fluctuated by an amount corresponding to a difference between the carrying amount of the material 2 by the roller 8 and that by the pair of rollers 3.  However, the diameter of the roller 21 is selected to be nearly equal to installation space between the pair of rollers 3 and a pair of intermediate rollers 7, so that the fixed tension (tension which is W/2 being the half of the gravity W of the roller 21) is always applied to the material 2 by the principle of a running block whatever position the up-and- down position of the roller 21 is. Thus, the material 2 is stably fed.

Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To correctly acquire synchronism fast even when there is an interference wave as to a radio system which transmits signals from different transmitters in the same timing at the same frequency and inserts a known pattern into the sent signals for synchronization. SOLUTION: This device is equipped with a 1st correlator 101 which correlates a received signal with the known pattern of a desired wave, a 2nd correlator 103 which correlates the known pattern of an interference wave with the received signal, and a synchronism deciding circuit 105 which decides synchronism according to the correlative values outputted from the 1st and 2nd correlators and decides that the output whose synchronism is detected first is synchronized.

Filed: 1987-08-21
Abstract: PURPOSE:To enable the easy and rapid discrimination of the direction of parts of many kinds by one apparatus, by making an object of measurement pass between a projector and a photosensor and by detecting the quantity of electricity of a photoelectric element of the photosensor. CONSTITUTION:A projector 1 and a photosensor 2 using a one-dimensional image sensor camera are installed at a proper space between them, and an object 4 of measurement can be moved on a rail smoothly between them. An output of a shadowed one of photoelectric elements 5 on the surface of the photosensor 2 is converted to be an electric quantity of low level, while an output of a light-irradiated one of them is converted to be an electric quantity of high level, and binary-coded signals thus obtained are inputted to a counter 6. When the object 4 of measurement moves across the photosensing field of the photosensor 2, a change occurs in the quantity of light second by the photosensor 2. This change is caught and processed by the counter 6 and a processing unit 10, and the direction of the object 4 of measurement is discriminated on the basis of it.

Abstract: PURPOSE:To keep a compression ratio in the air-fuel mixture inside a cylinder constant all the time, by opening or closing a subport according to an engine speed, while closing th subport in time of low speed and opening it in time of high speed according to the engine speed. CONSTITUTION:At engine low speed, centrifugal force will not work on balls 36, and a slider 27 fails to do its motion. Therefore, a valve 15 does not move at all, and a support 14 is left closed intact. When an engine comes high in speed, the number of revolutions in a gear 30 increases whereby th centrifugal force works on these balls 36, overcoming the tensile force of a spring 33 and causing these balls 36 to shift outward, and the slider 27 is set in motion. A lever connected to a pin installed in an outer circumference of the slider 27, a vertical shaft 23 connected to this lever and another lever 22 connected to an upper end of this vertical shaft are all rotated, making a valve rod 16 into slide motion, and the valve 15 is retreated by degrees, thereby opening the support 14 little by little.

Filed: 1981-12-21
Abstract: PURPOSE:To decrease execution time and to improve efficiency, by outputting a repetitive instruction signal when a counting signal of a counter counting down with the final instruction of a repetitive processing sequence is not zero. CONSTITUTION:A program counter PC designates a readout address (a) of a program memory MEM. First, the number of repetitions is set at a counter DEC and a repetitive address instructing the first instruction of the repetitive processing sequence is set to a repetitive address register BAR. Then, in executing the repetitive processing sequence, a count signal C stored in the counter DEC is counted by -1 with the final instruction of the repetitive processing sequence. Since a repetitive address (b) of the register BAR is transferred to the counter PC if the result of count is not zero in the discrimination circuit Z, a repetitive instruction signal (d) is outputted to a control circuit CNTL and the repetitive processing sequence is executed again.
