  • Publication number: 20060223469
    Abstract: A radio receiver device of the present invention may be used in a navigation system mounted on an automotive vehicle. The radio receiver device includes a receiver for receiving radio waves, a detector for detecting field intensity of the radio waves and a display panel for displaying the detected field intensity together with a name of the radio station and its carrier frequency. The field intensity is classified into several intensity ranks. The intensity ranks are displayed on the display panel by colors or other marks which are easily recognized by a driver. The driver is able to select one station having proper field intensity according to his preference without sacrificing his concentration on driving.

  • Patent number: 4845506
    Abstract: A side-looking array antenna system is disclosed in which the inclination angle of the antenna main beam is determined depending on the intervals of a plurality of antenna elements forming an array. A switch is provided to selectively connect one of the ports of an antenna feeder to a signal source or the like. The switch is used to select one of the ports of the antenna feeder as an excitation port, thereby reversing the direction of inclination of the antenna main beam. The antenna main beam can thus be directed in either of the two directions by the operation of the switch. Also, by using this antenna system, a Doppler radar vehicle speedometer with small calculation error, automotive radar and the like may be simply configured.

  • Patent number: 4775866
    Abstract: A two-frequency planar antenna incorporates a resonant antenna and a slot antenna which are arranged in a superposed manner on the same dielectric substrate so as to be operable independently without interfering with each other. The two-frequency planar antenna includes a front conductor plate arranged on one surface of a dielectric substrate to serve as a radiation conductor plate of a resonant antenna and a slotted conductor of a slot antenna, a back conductor plate arranged on the other surface of the dielectric substrate to serve as a grounding conductor of the resonant antenna and a reflector of the slot antenna, and a slot antenna feed line embedded in the dielectric substrate. The slot antenna feed line is arranged along an axis where an electric field in an excitation mode of the resonant antenna is reduced to zero and at least one slot is formed in the front conductor plate along the feed line.

  • Patent number: 4760402
    Abstract: An antenna system for use in an automotive vehicle comprises a housing mounted on a body of the automotive vehicle and having at least a portion of an upper surface thereof made of a dielectric material which transmits radio waves, at least one planar antenna disposed rotatably within the housing to receive radio waves transmitted through the portion of the upper surface of the housing made of the dielectric material, and driving means for driving the planar antenna to effect scanning of a radio wave receiving direction to search for the radio wave receiving direction of higher sensitivity. The housing protects the antenna system and maintains the fine appearance of the automotive vehicle. Further, the housing has a shape like that of an air spoiler, which makes it possible to maintain the satisfactory aerodynamic characteristic of the automotive vehicle.

  • Patent number: 4651085
    Abstract: An apparatus for measuring the ratio of alcohol contained in mixed fuel which flows through a fuel pipe to the engine. The fuel pipe is made of a high frequency signal permeable material such as rubber, teflon or nylon, for example. A microwave chamber is provided outside the fuel pipe, enclosing a part of the fuel pipe. The microwave chamber comprises a pair of wave guides opposed to each other with the fuel pipe interposed between them. One of the wave guides is provided with an antenna section for transmitting microwaves received from a microwave generator. The other wave guide is provided with a receiving antenna section for receiving the microwaves permeating through the fuel pipe through which the mixed fuel is flowing. The microwaves passing through the fuel pipe are attenuated according to the amount of alcohol in the fuel.
