  • Patent number: 9250737
    Abstract: An information apparatus includes a housing, first and second strain detectors, and first and second stress collectors that transmit distortion applied to a side surface of the housing to the first and the second strain detectors, respectively. Upon having the same amount of distortion is applied to the side surface of the housing, the first and strain detectors outputs different values a processing circuit. This information apparatus has a small size and can be accurately controlled.
    Type: Grant

  • Patent number: 7012480
    Abstract: A balanced type filter includes at least one balanced type terminal. At least one predetermined reactance element is connected between the balanced type terminal and another terminal. A parallel resonance circuit is formed by parasitic components existing between the balanced type terminal and the other terminal, and the reactance element. The other terminal is of balanced type or unbalanced type.

  • Patent number: 7010273
    Abstract: A high-frequency hybrid switch module arranged applicable to at least two different communications systems includes two low pass filters (LPFs), two phase shifters, a field effect transistor (FET) switch including FETs, and two SAW filters. The FETs and the SAW filters are mounted on a layered assembly including the LPFs and an electrode pattern of the phase shifters. The module can have a small overall size, a low cost, and a small loss, while being protected from static electricity. The module requires small number of low-noise amplifiers at a signal receiving side.

  • Patent number: 6891450
    Abstract: A longitudinal mode type surface acoustic wave filter comprising a first IDT electrode, second and third IDT electrodes, and first and second reflector electrodes are formed on a piezoelectric substrate. The upper electrode of the first IDT electrode is connected to one of balanced type terminals, and the lower electrode of the first IDT electrode is connected to the other balanced type terminal. Also, the lower electrode of the second IDT electrode is connected to an unbalanced type terminal, and the lower electrode is grounded. The lower electrode of the third IDT electrode is connected to the unbalanced type terminal, and the upper electrode is grounded.
