    Abstract: PROBLEM TO BE SOLVED: To stably receive radio waves regardless of the direction of a vehicle or the arrival direction of radio waves.
    SOLUTION: In an on-vehicle antenna 1, the other end portion 7b of an element 2 is separately formed from the vicinity a corner part toward the center of the corner. Since the element 2 is mounted on a front window 4 near the corner portion closest to the side surface of a vehicle body, when the radio waves come from the front of a vehicle 3, not only radio waves from the front of the vehicle 3 can be appropriately received but also even when the radio waves come from the rear side of the vehicle 3, diffraction waves from the side surface of the vehicle body or diffraction waves from the ceiling surface of the vehicle body can be easily received.

    Abstract: PROBLEM TO BE SOLVED: To prevent generation of the reception failure of a television broadcasting signal using a simple constitution.
    SOLUTION: When signal propagation distances between first and second antenna elements 1 and 2 installed to the front glass of a vehicle 5 and electronic equipment 6 mounted on the vehicle 5 as a noise signal source are respectively defined as L1 and L2, these first and second antenna elements 1 and 2 are arranged in such a positional relation that the signal propagation distance differences (L1-L2) are set to be 1/2 of the wavelength of the noise signal. Also, when this positional relation is satisfied, the first and second antenna elements 1 and 2 are arranged so that the positional relation that a ground wave television broadcasting signal as a reception object signal is received with an in-phase can be also satisfied simultaneously, with the assumption that the transmission source (television tower or relay station) of the television broadcasting signal exist at considerable distance.

    Abstract: PROBLEM TO BE SOLVED: To provide the frequency changeover device for the oscillation circuit in which an oscillated frequency is always made stable. SOLUTION: One terminal of a capacitor 11 is connected to a resonance circuit part of an oscillator in a frequency changeover circuit 10 and the other terminal is connected to an anode of a switching diode 12. A cathode of the diode 12 is grounded via a capacitor 13. A bias circuit 20 is connected across the diode 12 via inductors 14, 15 having an impedance sufficiently higher with respect to the oscillated frequency. The bias circuit 20 applies a voltage of 0 or Vp across the diode 12. The diode 12 is forward-biased and conductive when a switching signal is logical 0 and the diode 12 is reverse-biased and acts like a capacitor when the switching signal is logical 1. In the case that the diode 12 is reverse-biased, the capacitance of the diode 12 is made stable and a terminal connecting to the oscillator is made open. Thus, the oscillated frequency of the oscillator is made stable.

    Abstract: PROBLEM TO BE SOLVED: To provide an on-vehicle film antenna which does not obstruct view, can receive both a radio wave of a UHF band and a radio wave of a VHF band, and further can improve workability and economical efficiency. SOLUTION: The onboard antenna 1 is composed by integrating a looped antenna 2 and a monopole antenna 3. The element length of the looped antenna is formed in a length obtained by multiplying the wavelength of the radio wave of the UHF band by approximately "1/2". The element length of the monopole antenna is formed in a length obtained by multipying the wavelength of the radio wave of the VHF band by approximately "1/4". An electric power supply point 9 is common to these antennas. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To rewrite a radio program for carrying out radio communication by a radio communication device adequately without causing an increase in the whole system cost. SOLUTION: In a vehicle mounted display 1 equipped with a radio communication device 2, a new program to be rewritten is temporarily stored in a system memory 4 other than the radio communication device 2 when the radio program of the radio communication device 2 should be rewritten.

    Abstract: PROBLEM TO BE SOLVED: To improve the C/N of the oscillator by decreasing a loss in an inductance so as to improve the Q of a resonance circuit in the oscillator mounted on a multi-layer board and whose inductance of the resonance circuit is configured with a strip line. SOLUTION: At least one of punched layers 13, 15 are provided between a strip line layer 14 and earth layers 12, 16 having the layer 14 in between. Punched parts 131, 151 where no conductor is in existence are formed to parts opposite to a strip line 141 are formed to the punched layers respectively. Through the provision of the punched layers, a distance between the earthlayers with the strip line in between is increased and the thickness of the dielectric material between the earth layers is increased. Thus, the loss in the inductance is reduced and the C/N of the oscillator is improved by improving the Q of the resonance circuit.

    Abstract: PROBLEM TO BE SOLVED: To prevent radiation noise radiated out of an onboard device from sneaking into an onboard antenna by a simple method.
    SOLUTION: A parasitic element 8 with a route of a length that a wavelength of a received radio wave in the onboard antenna 1 is multiplied by 1/2, is arranged near a position whose distance from a meter device 5 is the wavelength of the received radio wave in the onboard antenna 1 multiplied by 1/4 between the meter device 5 which radiates radiation noise and the onboard antenna 1. The parasitic element 8 functions as a reflector, and a component corresponding to a length that a wave length of the received radio wave in the onboard antenna 1 is multiplied by 1/2, is reflected by the parasitic element 8 out of radiation noise radiated from the meter device 5.
