  • Patent number: 8597940
    Abstract: A gas cracking apparatus adapted to simultaneously efficiently discharge gas heavier than air and gas lighter than air resulting from assimilations of malodorous gas and greenhouse gas. The main frame of the gas cracking apparatus includes a closed metallic circular tube or angular tube. This tube is provided at its superior portion with a superior vent and provided at its inferior portion with an inferior vent, and the tube is further provided with a gas inlet disposed between the superior vent and the inferior vent.
    Type: Grant

  • Patent number: 8542067
    Abstract: Disclosed is an oscillation circuit. The oscillation circuit supplies predetermined oscillation signals to a generating circuit having a divider, a phase comparator, and a generator. A clock signal generating section generates clock signals in a cycle based on the comparison results from the phase comparator. A clock signal mask section masks a part of the clock signals generated by the clock signal generating section to generate the predetermined oscillation signals and supplies the predetermined oscillation signals to the divider. The clock signal mask section masks a part of the clock signals such that the cycle of sampling signals generated by the generator is the same as a predetermined cycle which is the cycle of a clock for use in generating image signals.

  • Patent number: 6926357
    Abstract: An automobile seat belt structure and an assist apparatus thereof which can provide a comfortable drive environment by not restraining a chest of an occupant by a seat belt is provided. An automobile seat belt structure and an assist apparatus thereof which can completely prevent a so-called submarine phenomenon, where an occupant slides out from a lower area of a belt when an accident occurs, is also provided.

  • Publication number: 20040164602
    Abstract: The invention provides an automobile seat belt structure and an assist apparatus thereof which can provide a comfortable drive environment by restraining nothing of a chest of an occupant by a seat belt, remove a pressure feeling of the chest for an occupant having a disease in the chest, an occupant having a hypertension, a headache or a retch and the like, and can secure safety with respect to various body types such as a physical build of the occupant, a child and a tall figure, a fatness and the like. Further, the invention provides an automobile seat belt structure and an assist apparatus thereof which can completely prevent a so-called submarine phenomenon that an occupant slides out from a lower area of a belt and strongly collides with a dash board or the like, when an accident is generated.

  • Patent number: 4513581
    Abstract: A refrigerator in which a refrigerator evaporator and first freezer evaporator are serially connected to a condenser and compressor. A first bypass path is defined in parallel with the refrigerator evaporator for supplying refrigerant only to the first freezer evaporator and a second bypass path including a second freezer evaporator likewise defined in parallel with the refrigerator evaporator for quickly reducing the freezer temperature. A differential pressure regulator valve is connected between the condenser and the refrigerator evaporator.
