In an information transmitting system for radio-transmitting information between a fixed station and a mobile station moved within a predetermined moving range, an antenna apparatus is provided on the fixed station side. The antenna apparatus includes a large number of unit antennas, each of which functions as an antenna. These unit antennas are mutually connected to each other, and are arranged along the moving range of the mobile station. The information is transmitted/received in a radio transmission mode between the mobile station and the fixed station via an antenna of the fixed station and the antenna apparatus.

A washing tub and an outer tub are inclined together by a tub posture tilting mechanism. The tub posture tilting mechanism is constituted of a link mechanism structure. One of the tub posture tilting mechanism comprises mainly a pair of beams mounted integrally on the outer tub, a pair of bases mounted turnable on the beams, a crank mounted turnable on a rear base and an arm mounted turnable on the crank and mounted on a motor. The motor is mounted integrally on the rear base and drives the tub posture tilting mechanism. Another of the tub posture tilting mechanism comprises mainly a pair bases mounted turnable on the outer tub, a crank mounted turnable on a rear base and an arm mounted turnable on the crank and mounted turnable on a motor. The motor is mounted integrally on the outer tub and drives the tub posture tilting mechanism. A delicate washing clothes is washed softly in a triangular washing region at a uniform inclined state of the washing tub. The delicate washing clothes is washed softly by a reciprocate move of the washing tub in a variable washing region at a variable inclined state of the washing tub.

A variable-displacement rotary compressor comprises a rotor with a vane and a side plate disposed to abut a side face of the rotor. The side plate has a suction port formed therein to open to both a working chamber abutment face thereof abutting to the rotor side face and a low pressure chamber, and the rotor has a suction path formed therein to open to the working chamber and to an abutment surface of the rotor. The suction path of the rotor communicates with the suction port of the side plate through rotation of the rotor so that a fluid is sucked from the low pressure chamber into the working chamber under suction stroke through the suction path and the suction port.

A magnetic head positioning apparatus including a chassis, a driving device provided on the chassis, a guide member provided on the chassis, a carrier movably provided on the guide member, a first metallic head support mounted on the carrier and adapted to support a first magnetic head, and a second metallic head support mounted on the carrier and adapted to support a second magnetic head which is disposed to oppose the first magnetic head. A coupling member is formed on the first head support and directly connected to the driving device. By moving the coupling member by the operation of the driving device, the carrier is moved along the guide member through the first head support. Thus, it is possible for the magnetic head positioning apparatus to possess excellent resistance to environmental changes and to effect highly accurate positioning of the magnetic heads.

Apparatus for positioning magnetic head

A mechanism for supporting magnetic heads has gimbal plates which support both magnetic heads in such a manner than the magnetic heads oppose to each other across a flexible double-sided magnetic disk. The magnetic heads are resiliently pressed onto the magnetic disk through movable members which are resiliently biased.

A coordinate input apparatus including transparent upper and lower strip electrodes arranged to confront each other intersectionally with a transparent press-conductive member being placed between the upper and lower electrodes. The electrode arrangement formed on a transparent substrate is fitted on a display screen, allowing the operator to press the coordinate surface by the finger tip while viewing the display. An upper and lower strip electrodes become conductive by being pressed, generating a signal which represents the pressed position on the coordinates.

Coordinate input apparatus

A mechanism for moving a magnetic head of a type at least having a chassis, a motor mounted on the chassis, a lead screw driven by the motor either in a normal rotational direction or in a reverse rotational direction, guide shafts mounted on the chassis, and a carriage carrying a magnetic head thereon and slidably mounted on the guide shafts. A connecting cam body is provided to convert the rotational movements of the lead screw into a reciprocating movement of the carriage, and the carriage is forced to one direction by the connecting cam body.

Mechanism for moving a magnetic head

A magnetic head has a slider and a recording and reproducing gap which slide-contact a magnetic disk and is pivotally supported. The recording and reproducing gap of the magnetic head is disposed so as to be offset toward the forward end of the slider in terms of the direction of rotation of the magnetic disk, whereby it is possible to obtain a stable state of contact between the recording and reproducing gap and the magnetic disk.

Magnetic head and support therefore

A magnetic recording and reproducing apparatus includes a support assembly and a plurality of magnetic heads supported by the support assembly for recording audio information signals on and reproducing previously recorded audio information signals from a magnetic disc. The magnetic heads are positioned relative to the magnetic disc by a magnetic head moving arrangement which is coupled to engage the disc so as to automatically eject the disc from the magnetic heads.

Magnetic recording and reproducing apparatus

A magnetic head mounting device of a magnetic recording apparatus including a carriage, a first magnetic head supported by the carriage, a head arm supported by the carriage for movement in a vertical direction, and a second magnetic head supported by the head arm and disposed in spaced juxtaposed relation to the first magnetic head, wherein both or one of the first magnetic head and second magnetic head is mounted on the carriage or head arm through a gimbal. The gimbal includes a head mounting section for mounting the first magnetic head or second magnetic head thereto, and a supported section disposed outwardly of the head mounting section and partly supported by projections located at the carriage or head arm, the head mounting section and supported section being partly connected together through a plurality of connections.
