Inventor: NISHIHARA SUSUMU
IPC: G01R33/32
Filed: 1986-08-22
Abstract: PURPOSE:To obtain a stable and highly efficient radio frequency magnetic field generating detector by a method wherein 2nd and 3rd variable capacitors are connected to the respective terminals of 1st variable capacitor to form a balanced impedance matching circuit and a balun is connected to the matching circuit. CONSTITUTION:2nd variable capacitor 8b and 3rd variable capacitor 8c are connected to the respective terminals of 1st variable capacitor 8a which provides a capacitive coupling between a pair of adjoining wings 1b to form a balanced impedance matching circuit 8 and a balun 9 is connected to the balanced impedance matching circuit 8. Then the resonance frequency and the impedance matching frequency of a microwave circuit which functions as an equivalent series resonance circuit are adjusted by the 1st variable capacitor 8a. As a result, voltages whose magnitudes are equal and polarities are opposite to each other are applied to electrodes 7a and 7b so that the balanced feeding of the LC series resonance circuit can be completely realized.

Abstract: PURPOSE:To prevent occurrence of cracks in a freely forged surface, by freely forging a composite material composed of an Al or Al-alloy matrix and short-fiber dispersant under a condition where the side of the material are kept by a metallic frame which is richer in plastic-workability than the composite material. CONSTITUTION:A composite material 2 is prepared by scattering short fibers of C, SiC, Al2O3, etc., as a reinforcing material in a matrix made of Al or an Al-alloy. The freely forging surface 6 on the side of the composite material 2 which is not directly contacted with a forging tool is kept with a metallic frame 1 made of Al, Al-alloy, etc., which is richer in plastic-workability than the composite material 2. It is desirable to set the thickness 8 of the metallic frame 1 at about >=30% of its height 9 and it is appropriate to set the clearance between the frame 1 and material 2 at about <=5mm. Thereafter, a forging pressure is applied to the surface 12 of the metallic frame 1 and the surface 4 of the material 2 contacting with a forging tool (not shown in the figure) in the direction shown by the arrows by means of the forging tool. Therefore, the composite material 2 is forged together with the metallic frame 1 and occurrence of cracks in the free forging surface 6 can be prevented.

Title: Picture magnifying/reducing circuit
Inventor: MIYAKE EITA
IPC: G06T3/40
Filed: 1984-09-21
Abstract: PURPOSE:To prevent the deterioration of picture quality when a reduction ratio is set at <=1/2 by supplying a shift clock to a source shift register with a frequency double as much as the actual reduction ratio. CONSTITUTION:In case the reduction ratio (k) is set at <=1/2, the vertical lines are selected in the number double as much as the case of the horizontal reduction. These selected lines are loaded alternately to a vertical OR latch circuit 53 and an OR gate 54. The output of a gate 54 is equal to the OR of the picture information on the lines set previously to a latch circuit and the picture information obtained this time. This OR is loaded to a source shift register 41. Thus the vertical reduction is done. For the horizontal reduction, the double value is set for a register 21 and a clock 45 is produced with a frequency double as much as the actual reduction ratio. The transfer speed from the register 41 is set at double as high as the conventional level. Thus it is possible to obtain a picture of a 1/4 reduction ratio with no black omission.

Filed: 1983-10-24
Abstract: PURPOSE:To prevent a resistance value of poly-Si resistor to change in accordance with a potential of lower substrate part by forming impurity diffusion layer to the lower semiconductor substrate region of poly-Si resistor and fixing a potential of such impurity diffusion layer to a constant. CONSTITUTION:An impurity layer 21 is formed in the region including the lower part of the poly-Si resistor 3 forming region at the surface of semiconductor substrate 1. An insulation film 2 is also formed on this substrate 1 and a poly- Si resistor 3 is formed at a part of the upper region of layer 21 on the film 2. In a semiconductor device of such constitution, for example, the substrate 1 is fixed to the ground potential and the layer 21 is fixed to the same potential as the substrate 1. Thereby, potential does not change at the lower part of resistor 3 and therefore any effect is not exerted on the resistance value of resistor 3.

Abstract: PURPOSE:To prevent bending of a member to be cut during shearing, by applying the restriction in the vertical direction through a support during the initial stage of shearing by use of an upper cutter, in addition to applying a restriction force in the longitudinal direction onto the member to be cut, and releasing said restriction afterwards. CONSTITUTION:In the initial stage of shearing in which an air pressure is set to a prescribed value by a pressure setting device 14 and an upper cutter 3 is lowered and a member 5 to be cut is positioned by a stopper 2, if a shearing load is applied onto a support 4, the compressed oil in a hydraulic cylinder 12 counterflows successively into a vacant oil tank 18 through the pressure setting device 14, and the compression of air in the pressure setting device 14 is increased, and a back pressure acts onto a support 4. Therefore, the support 4 lowers in the alignment with the upper cutter. After shearing, a lever 22 and the hydraulic cylinder 12 lower, and the support 4 is separated from the cut material 5, and the vertical restriction is released, and the product 6 cut completely by the upper cutter 3 is pushed downward. Thus, bending of the member to be cut can be prevented.

Title: Bean curd
Inventor: OOTA TOSHIYUKI
IPC: A23L11/00
Filed: 1982-11-13
Abstract: PURPOSE:To obtain a bean curd having improved preservability, by filling a vessel with a soybean milk or fermented soybean milk containing a coagulating agent, closing the vessel, heating the soybean milk under pressure, sterilizing the soybean milk, and cooling the sterilized bean curd under pressure. CONSTITUTION:A soybean milk or fermented soybean milk containing a coagulating agent or both are filled into a vessel having a low oxygen permeability and closed. The closed vessel is then heated under pressure, fully sterilized and cooled under pressure to take out the resultant bean curd from the vessel. Calcium sulfate, calcium lactate, glucono-delta-lactone, etc. may be cited as the coagulating agent, and a small amount thereof is enough. The hardness of the bean curd can be adjusted by the amount of the coagulating agent. The presence of a small amount of a potassium or sodium salt, e.g. potassium chloride or sodium chloride, permits the inhibition of the coagulation by the heat sterilization under pressure. Thus the hardness is not too high.
