  • Patent number: 10608548
    Abstract: A power conversion device that can prevent decrease in sealing properties between a case and a fixed member. The power conversion device has a case, a fixed member, and a seal member. The case has a metallic case body. The fixed member is fixed to the case from the outside of the case. The seal member adheres closely to both the case and the fixed member to ensure water-tightness between the case and the fixed member. The case is partly formed with a corrosion-resistant portion that is less likely to suffer corrosion than the case body. The fixed member is attached to the corrosion-resistant portion via the seal member.

  • Publication number: 20190160466
    Abstract: The present invention provides a tool that can analyze a target in a sample with simple operations and can be downsized, and an analysis method using the same. The analysis cell of the present invention includes: a main substrate: a sample inlet cover member; and a gas outlet cover member. The main substrate includes a flow path, an inlet for a sample, and a gas outlet, and the inlet and the gas outlet communicate with an outside. The inlet communicates with an upstream end portion of the flow path and the gas outlet communicates with a downstream end portion of the flow path. The flow path has a shape that expands from an upstream side toward a downstream side of the flow path. The sample inlet cover member is a liquid-tight member and can be fixed to the inlet when the sample inlet cover member is in use. The gas outlet cover member is a liquid-tight and gas-permeable member and can be fixed to the gas outlet when the gas outlet cover member is in use.

  • Patent number: 7236519
    Abstract: First and second transmission paths are provided between a first port to which an antenna is connected and a second port to which a transceiving circuit is connected. First to fourth reception filters, an amplifier circuit, and first to fourth hybrid circuits are provided on the first transmission path. A reception signal from the antenna is transmitted from the first port to the second port via the first hybrid circuit, the first and second reception filters, the second hybrid circuit, the amplifier circuit, the third hybrid circuit, the third and fourth reception filters, and the fourth hybrid circuit in this order. This reception signal does not return to the amplifier circuit, whereby the reception signal is prevented from oscillating due to positive feedback.

    Abstract: A dielectric filter, a composite dielectric filter, a dielectric duplexer, a dielectric diplexer, and a communication apparatus, in which isolation between adjacent dielectric filters can be obtained, and deterioration of filter characteristics can thereby be prevented. A plurality of dielectric resonators formed by disposing dielectric cores in cavities, and coupling loops for coupling to predetermined resonance modes of the dielectric resonators, are combined to form a dielectric filter. The dielectric resonators and the coupling loops are arranged in such a manner that when the dielectric resonators of the dielectric filters are close to each other, the directions of the coupling portions of the adjacent coupling loops are substantially vertical to each other.
