  • 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.

  • 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.

  • Patent number: 6981307
    Abstract: The measurement and adjustment of characteristics of a filter alone are performed using a connector adapter, in which a pin of the filter becomes a central conductor of the adapter. The filter after the adjustment and a device which is not adjusted are assembled, such that the filter and the device are connected by connecting the pin provided in the filter and a transmission line provided in the device. Accordingly, the time for adjustment is shortened and the adjustment for obtaining the desired characteristics of the filter module are made easy.

    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.
