    摘要： An antenna unit for a car navigation device includes a unit casing accommodating a circuit board and an antenna body and having a bottom cover in which a bottom recess is formed. A permanent magnet ring magnetically held on a back yoke is fixedly set in the bottom recess, the permanent magnet ring being used to magnetically hold the bottom cover on the surface of an object so that the antenna unit is detachably mounted on the object. In the antenna unit, an adhesive seal is bonded to the of the permanent magnet ring which surface confronts the surface of the object.

    摘要： A navigation system comprises: an antenna 12 which receives radio waves from a GPS satellite; a controller 15 which perform various operations to detect the present position of the car from the output signal of the antenna 12; and an image display 17 which, being controlled by the controller, displays a map, the present position of the car, etc., and a traveling-direction indicator 30 which includes a sign section made up of arrow marks or triangular marks to indicate a direction in which the car should move on. With the system, as the car comes near a branching guide point such as a crossing, the controller 15 operates to cause the sign section of the traveling-section indicator 30 to turn on or flicker to indicate a direction in which the car should move one.

    摘要： A hermetically sealed case, has a space between a top case and a bottom case which can be completely sealed by means of a waterproof packing, and in which an area around a connecting cable is completely sealed. A first case having an annular projection formed at the periphery thereof is assembled to a second case having an annular groove having a shape corresponding to that of the projection of the first case formed at the periphery of the second case. An elastic member is provided between the projection of said first case and the groove of said second case. The width of said projection is smaller than the width of said groove, and said projection is fitted within said groove in a transverse direction. The elastic member deflects toward the groove, that is, deflects such that the ends of the elastic member are drawn toward the projection. Line contact is established between the corners of the projection and the elastic member, and also between the corners of the groove and the elastic member. A through hole through which the connecting cable is led is provided in one of the cases. The elastic member is pressed by a press-fitting member, and is press-fit between the through hole and the connecting cable. Sealing of the pair of cases and sealing of the area around the connecting cable performed independently of each other.

    摘要： An antenna unit and a receiver having such an antenna are disclosed. The antenna includes an antenna body; a first antenna provided on the antenna body for receiving signals transmitted from satellites; at least one second antenna provided on the antenna body for receiving signals transmitted over the earth; a mixer provided in the antenna body for mixing or combining the signals received by the first and second antennas to output the mixed signals as a single output. Further, the receiver includes, in addition to these elements of the antenna unit, a signal separating device for separating the mixed signals into the signal received by the first antenna and the signal received by the second antenna, respectively and then outputting them; and a single cable which connects the mixer and the single separating device to supply the mixed signals thereto. Accordingly, since the antenna unit is provided with the mixer which combines or mixes the received signals and outputs the mixed signals as a single output, only one cable it required to connect the antenna unit to the signal separating device, thereby enabling to reduce the number of cables used for connecting respective antennas with respective corresponding electrical devices.
