  • Patent number: 10883988
    Abstract: Definitive diagnosis and early start of treatment cannot be made for tuberculosis since conventional methods for detecting a Mycobacterium tuberculosis complex require a long time plus enormous labor and expense. Because detection is difficult to perform directly from a biological sample, if the biological sample contains no or a very small amount of the Mycobacterium tuberculosis complex-specific secretory protein, there is a risk infection with the Mycobacterium tuberculosis complex will be missed.

  • Patent number: 10823730
    Abstract: Definitive diagnosis and early start of treatment cannot be made for tuberculosis since conventional methods for detecting a Mycobacterium tuberculosis complex require a long time plus enormous labor and expense. Because detection is difficult to perform directly from a biological sample, if the biological sample contains no or a very small amount of MPT64, there is a risk infection with the Mycobacterium tuberculosis complex will be missed. The present method and a kit address these long-standing needs by more rapidly and conveniently detecting a Mycobacterium tuberculosis complex, without culturing a biological sample containing the Mycobacterium tuberculosis complex, in which a biological sample is subjected to a heat-treatment so as to extracellularly secrete a Mycobacterium tuberculosis complex-specific secretory protein, particularly, MPB64, and subjecting the resulting treated sample to an immunological measurement/assay.

  • Patent number: 8164882
    Abstract: A pressure regulating valve is provided on a terminal plate of a capacitor. This pressure regulating valve includes a gas permeable sheet, a valve body made of silicone rubber, a packing, and a cap. The gas permeable sheet that prevents permeation of electrolyte is provided so as to close a hole created in the terminal plate. The packing is interposed between the valve body and the gas permeable sheet, and is made of an elastic material with moisture permeation resistance higher than that of silicone rubber. The cap is fixed onto the terminal plate and covers the valve body and the packing such that the valve body and the packing are retained in a compressed state with respect to the terminal plate. The valve body and the packing are provided away from the gas permeable sheet.

  • Patent number: 8064191
    Abstract: According to the configuration and the manufacturing method of forming a moisture proof agent on both surfaces of a circuit substrate after soldering a capacitor connection pin in a vertical direction to the circuit substrate, and electrically connecting the capacitor so as to be in a perpendicular direction to the length direction of the capacitor connection pin at the upper space of the circuit substrate, the possibility of the moisture proof agent attaching to the capacitor is eliminated, the productivity enhances since the moisture proof agent can be easily formed on both surfaces of the circuit substrate, and a capacitor unit of miniaturized and low height configuration is realized since the capacitor is mounted in the horizontal direction in the upper space with respect to the circuit substrate.

  • Patent number: 8045320
    Abstract: A capacitor includes a wound element, and externally take-out electrode members corresponding respectively to a first pole and a second pole and connected to each one of end faces of the wound element. This capacitor features that the wound element is positively fixed to the externally take-out electrode members, and has advantageously a small internal resistance. Collectors in inner circumference region of the wound element are bent in an opposite direction to a core of a winding shaft, and collectors in an outer circumference region are bent toward the core of the winding shaft. End faces of these collectors are connected to a lid, thereby forming a first pole of the capacitor, and end faces of those collectors are connected to a housing, thereby forming a second pole of the capacitor.

  • Patent number: 7916454
    Abstract: A pressure control valve provided on a terminal plate of a capacitor includes a filter, a valve body and a cap. The filter is provided so as to close a through-hole disposed in a terminal plate and is composed of a gas permeable sheet preventing permeation of the electrolyte solution. The valve body is formed of an elastic material, has a cylindrical part and a bottom part, and is disposed so that the bottom part covers the through-hole of the terminal plate. The cap is fixed to the terminal plate, covers the valve body, and holds the valve body in a composed state with respect to the terminal plate. The cap is provided with a vent hole. The valve body and the filter are spaced apart from each other.

  • Patent number: 7817404
    Abstract: A capacitor includes a metal case having an opening, a capacitor element accommodated in the metal case, an electrolyte accommodated in the metal case, and a sealing rubber sealing the opening of the metal case. The sealing rubber seals the opening of the metal case while the sealing rubber is compressed to have a stress applied thereto. The stress is not lower than 0.5 MPa and not higher than a predetermined maximum value. This capacitor prevents the electrolyte from leaking, thus having high reliability.

  • Patent number: 6631071
    Abstract: A reliable capacitor module is provided which can solve the following problem: when a plurality of capacitors is mounted on a wiring board, the wiring board is distorted and deformed by the weight and cracks appear on mounting holes and the main body of the wiring board. The bottoms of metallic cases of the capacitors are fit in recesses formed on a mounting plate. In this state, lead wires drawn from the upper surfaces of the capacitors are electrically connected via the wiring board. With this configuration, a weight load of the plurality of capacitors is not applied at all, thereby preventing distortion and deformation of the wiring board and vibration causing cracks on the main body of the wiring board.
