摘要:
A mobile terminal displays a screen image provided by an image data which is produced. An in-vehicle apparatus is fixed to a vehicle or is mounted on the vehicle to be portable. The mobile terminal sends the image data to the in-vehicle apparatus through communication such that a vehicle display portion of the in-vehicle apparatus displays a screen image provided by the image data. In a case where a communication between the in-vehicle apparatus and the mobile terminal is established, when one of the mobile terminal or the in-vehicle apparatus, in which an input operation has been performed prior to the other of the mobile terminal or the in-vehicle apparatus, is in operation, only the one of the mobile terminal or the in-vehicle apparatus is operable.

An array antenna apparatus in which an SN ratio is improved. Antenna elements having transmission modules, respectively, are arranged in plurality, wherein the plurality of transmission modules respectively have transmission signal generators that each output a transmission intermediate frequency signal, local oscillation signal generators that each output a local oscillation signal, and transmission mixers that each mix the transmission intermediate frequency signal and the local oscillation signal with each other, thereby to carry out frequency conversion to a transmission high frequency signal. A reference signal source inputs a reference signal to the transmission signal generators and the local oscillation signal generators. The transmission intermediate frequency signal and the local oscillation signal are synchronized with each other by the reference signal.

In addition, a large directional gain, a low side lobe level and a low power consumption are achieved, as a phased array antenna apparatus using a transmission module.
摘要:
A high pressure fuel pump for use with a direct injection engine having a housing which defines a pump chamber. A port is formed in the housing which fluidly connects a fuel in the passageway with the pump chamber. An elongated valve is movably mounted within the housing between an open and a closed position. In its open position, the inlet passageway is fluidly connected with the pump chamber while, conversely, in the closed position the fuel valve blocks the fluid flow between the inlet passageway and the pump chamber. A circuit controls the deceleration of the valve to reduce pump noise.
