  • Patent number: 9518587
    Abstract: An air compressor comprising: a tank (50), a compression mechanism (30), a motor (5) and a control circuit (7). The control circuit (7) includes a CPU (70) and a storing unit (74) which stores a control program, the compressor operation history and a plurality of operation modes. Each of the operation modes is defined by two setting values: a reference restart pressure value and a motor rotational speed value, at least one of these values being different from among the plurality of modes. The control circuit (7) executes one of the plurality of modes as a target mode in which the control unit controls the motor to restart by comparing the pressure in the tank with the reference restart pressure and rotates the motor at the rotational speed of the target mode. The control circuit changes the target mode from the one of the plurality of modes to another one of the plurality of modes based on the compressor operation history.

  • Patent number: 8410989
    Abstract: An antenna for receiving electromagnetic waves in a desired frequency band, includes a radiating conductor and a ground conductor, a feeder part, a wavelength-shortening section, and a magnetic field applying section. The radiating conductor and a ground conductor resonate at a resonance point frequency. The feeder part is configured to feed the radiating conductor with electricity. The wavelength-shortening section in which a magnetic body having both a dielectric property and a magnetic property is disposed close to the radiating conductor shifts the resonance point frequency into a band lower than the desired frequency band by a wavelength-shortening effect obtained based on the dielectric property and the magnetic property. The magnetic field applying section is configured to apply a magnetic field to the magnetic body so as to reduce a magnetic loss due to the magnetic body.

  • Patent number: 8278142
    Abstract: A method for forming electronic assemblies includes providing a plurality of IC die each having IC bonding conductors and a workpiece having workpiece bonding conductors. A curable dielectric film is applied to the IC bonding conductors or the workpiece surface. The plurality of IC die are placed on the workpiece surface so that the plurality of IC bonding conductors are aligned to and face the plurality of workpiece bonding conductors to provide a first bonding. The placing is performed at a vacuum level corresponding to a pressure <1 kPa, and at a temperature sufficient to provide tackiness to the curable dielectric film.
