Title: Environmental radiation dose rate meter and inspection method thereof
Inventor: YAMAMURA KIYOHITO
IPC: G01T7/00
Filed: 1992-02-03
Abstract: PURPOSE:To eliminate the troublesomeness of requiring to remove radiation dose rate meter equipment to carry it into an establishment with a calibrating apparatus in order to inspect the soundness of an environmental radiation dose rate meter since the set place is apt to be in a living area and strong radiation source is not to be used also from a legal point of view. CONSTITUTION:The voltage of bias supply 4 is selected to use an ionization chamber detector 1 in a range of its output current being proportional to a radiation dose rate. In a low radiation dose rate range, radiation source unrestricted by the law is radiated onto the detector 1 for inspection, with a change-over switch 12 left connected to the detector 1. In a high radiation dose rate range, the changeover switch 2 is switched onto the current generator 13 side, and the proportional constant of the radiation dose rate versus the output current of the detector 1 obtained in the inspection is used to perform inspection by the current of the current generator 13.

Title: Self-synchronous logic circuit
Inventor: PARASHIOSU ARUBERUTO
IPC: H03K19/0948
Filed: 1993-02-04
Abstract: PURPOSE:To design the circuit of a smaller area by defining a logical 1 to be (0, 1), logical 0 to be (1, 0), an invalid value to be (0, 0) and a fault/test value to be (1, 1). CONSTITUTION:When an input (a) or (b) is (1, 1) representing a fault/test state, outputs of NAND gates 401, 402 go to 0 and outputs (c) of NAND gates 500, 900 go to (1, 1) representing a fault/test state. With the inputs a, b set to an invalid (0, 0), when both inputs are invalid and not a fault/test value and when both inputs are (1, 0) and (0, 1), outputs of all NAND gates go to 1 and outputs (c) of both output gates 500, 900 are invalid (0, 0). Moreover, with both inputs (a), (b) set to 1, 0 respectively, the outputs (c) are (1, 0), and when the inputs (a), (b) are 0, 1 respectively, the outputs (c) are (0, 1). Thus, an AND logic is formed by less number of MOS transistors(TRs) and problems of an area of the logic circuit and the delay time or the like are solved.

Title: Laminated composite
Inventor: SHIBAYAMA KOICHI
IPC: B32B7/02
Filed: 1994-02-14
Abstract: PURPOSE:To enable complicated post-processing by preventing the occurrence of foam breaking at the time of vacuum molding by laminating polyolefinic resin foam high in thickness recovery and a skin material. CONSTITUTION:A polyvinyl chloride resin sheet, a thermoplastic elastomer sheet, a cloth like article or leather is used as a skin material to be bonded to polyolefinic resin foam by an adhesive to form a laminated composite. When the apparent density of the polyolefinic resin foam is too low, the strength of the foam is lowered and, therefore, foam is broken under load and distortion is not restored. When the apparent density of the foam is too high, the flexibility of the foam is lowered. Therefore, the apparent density of the foam is pref. 0.03-0.20g/cm<3>. The thickness of the foam is set to 1.5-5.0mm. The thickness recovery of the foam measured when load of 20g/cm<2> is applied to the foam at 20-110 deg.C for 1hr and, after the load is removed, the foam is allowed to stand at 23 deg.C for 1hr is set to 86% or less. By this constitution, the secondary processing of a complicated shape can be performed.

Title: Axial piston pump/motor
Inventor: YAMAMURA MASAYA
IPC: F03C1/24
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To constantly keep a clearance between a cover and a port block even in the rotation of the port block, and to prevent the liquid leakage and the seizure and the like of a sliding contact surface by forming the sliding contact surface with the cover, of the port block into the spherical shape having its center on an intersection of a spindle and a shaft of a cylinder block. SOLUTION: When a cylindrical block 3 is rotated by a driving source through a spindle 2, a kidney port block 9 receives the torque by the sliding resistance, but it rotates in the rotating direction of the cylinder block 3 for a clearance for fitting of a pin 16 and the clearance formed by abrasion. But by forming the clearance on a cross section into the spherical shape with the center P of the tilt rotation, on a position at a predetermined distance from a center P of the tilt rotation of a convex spherical end surface 92 of the block 9 and a concave spherical end surface of the cover 12, the clearance can be constantly kept regardless of the rotation of the block 9. Whereby the increase of the liquid leakage, the seizure of the sliding contact surface and the like can be prevented, and the reliability in operation can be improved.

Filed: 1981-02-12
Abstract: PURPOSE: To perform flocculation of the emulsion in waste water contg. resin emulsions easily and economically by conducting DC by the use of polyvalent metallic electrodes.  
     CONSTITUTION: Resin emulsion waste water of washing is stored in an electrolytic cell 1, and NaCl is dissolved at about 0.1% in this. DC current of 100W 200A is conducted for 60W140min at 12W18V by using Fe or Al electrodes 2 and the polyvalent metallic ions generated by this are acted upon emulsion particles, whereby the interfacial electric charge of the surfaces is neutralized and the contact of the particles with each other is made easy. In this way, the milky turbid washing water is flocculated and separated; part thereof floats and the other part settles, thereby producing a transparent liquid layer at the intermediate. The intermediate layer is pumped out into a filter vessel 4 with a lift pump, thence it is filtered with filter media 5, and is sent into a discharge channel 6. Thereafter, the precipitate is sucked up with a pump 7 into a filter bed 8, to which a mixture of 1:1 borax, boric acid is charged and the precipitate is dehydrated.

IPC: H02K17/30
Filed: 1992-02-04
Abstract: PURPOSE:To detect the phase revolution of a three-phase inductor safely, certainly, and quickly and besides with small facility by connecting a phase tachometer to each terminal of a three-phase inductor, and connecting single-phase power sources to the optional two terminals of the three-phase inductor. CONSTITUTION:A single-phase power source 3 at voltage lower the rated voltage of a three-phase inductor 1 is connected to the optional terminal of the three- phase inductor 1 through a switch 4. A phase tachometer 5 is connected to the terminals U, V, and W of the three-phase inductor. A switch 4 is turned on, and the three-phase inductor 1 is rotated at about rated speed so as to observe the operation state of the phase tachometer 5. Since the voltage of phase geared to the direction of the rotation of a rotor is induced, it can be detected that the phase revolution is positive, if the operation state of time phase tachometer 5 is normal rotation, and that the phase revolution is reverse if it is reverse revolution. This way, the phase revolution of the large capacity of three-phase inductor can be detected safely, certainly, quickly, and besides with small facility.

Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To improve image reproducibility and water resistance by forming the outermost layer of the protective coat of an optical recording medium capable of printing with a binder resin contg. fine particles having a porous structure in the surfaces. SOLUTION: A colloidal sol of fine particles of porous alumina hydrate represented by the formula Al2 O3n (OH)2n .mH2 O [where (n) is an integer of 0-3 and (m) is an integer of 0-10] is used for the protective coat of an optical recording medium. In order to keep good surface flatness and good ink absorbability, the average particle diameter of the alumina sol is regulated to 50-250 nm. In order to keep good adsorption and fixation of a coating material in ink and good ink absorbability, the average pore radius of the particles is regulated to 20-200 Å and the occurrence of irregular color due to the mixing of adjacent inks different from each other in color as well as the blurring of an image is prevented. The pore volume of the particles is regulated to 0.4-0.6 cc/g and the BET specific surface area is regulated to 70-800 m<2> /g.  Since the particles have such a microporous structure in the surfaces, ink is quickly absorbed by capillarity and blurring can be prevented even by contact with water.

Abstract: PURPOSE: To keep the stable contact of a heating body with cooling fins, by fixing the fins to the heating both together with auxiliary rings having a coefficient of thermal expansion equal or inferior to that of the heating body.  
     CONSTITUTION: Auxiliary iron rings 20 are shrunk fitted to the exterior of cooling  fins 17.
