Title: Cassette eject device for tape player
Inventor: FUJIMOTO MASAMI
IPC: G11B15/675
Filed: 1988-11-30
Abstract: PURPOSE:To simplify a mechanism, to decrease a fault and to reduce a cost by linking an eject member and an operating member by an interlocking means, executing eject operation, canceling the link of a linking means when the operation is completed and executing the spring return of the eject member. CONSTITUTION:An operating member 5 is operated by driving force and eject members 39 and 40 push a tape cassette A, which is inserted to a holder 24, and eject the tape cassette A. An interlocking means 41 is linked to the eject members 39 and 40 and the eject members 39 and 40 are moved in an eject direction by the operation of the operating member 5. Then, when the eject operation is completed, the link with the operating member 5 is canceled and the eject members 39 and 40 are returned by the energization of an energizing member 44 to a position before the eject is started. Accordingly, since the eject members 39 and 40 are automatically returned to the operation before the eject by spring energization when the eject operation is completed, the operation of the operating member 5 can be also used for the moving operation, etc., of the holder 24. Thus, the mechanism can be simplified, the cost can be reduced and the fault can be decreased.

Abstract: PURPOSE: To improve the precision of the estimated value of the vehicle position by computing the error indexes expressing the three-dimensional coordinate component errors and average pseudodistance differences by receivers whose positions are known and employing the results for vehicle positioning calculation. CONSTITUTION: Ephemeris data and distance data are received from respective satellites 102a-102d at a base station 220 and the pseudodistance to each satellite 102 and the position of each satellite 102 are computed.

IPC: H03H9/25
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To reduce the ripple within a band which is generated due to the shape and dimension of an IDT(interdigital transducer) except three kinds of main unwanted waves of an end face reflection, a bulk wave and TTE(tripple transit echo) in a surface acoustic wave device in which the squareness ratio of the pass band width of a frequency characteristic is large and the electrode logarithms of the IDT with weight are numerous.

Filed: 1987-11-28
Abstract: PURPOSE:To lighter a burden without making access to a storing means in plural times by controlling the opening/closing of respective gates with a microcomputer when sub code data are overlap-written to the sub code area of a magnetic recording medium. CONSTITUTION:When the sub code data are written with being overlapped in eight times, a gate control signal (A, B, C, D) to be outputted from a microcomputer 50 is set to a (1, 0, 0, 0). Accordingly, the address output of an address counter 61 is passed through an AND gate 11 only. For a block address to be given to a memory 4, (0, 0, 0, 0) and (0, 0, 0, 1) are alternately given respectively in eight times and on a magnetic tape 8, the sub code data of a block address 0, 1 of the memory 4 are written in eight times, namely, written with being overlapped in eight times. In case of the overlap-writing, it is not necessary to make access to a recording means in plural times and since it is enough only to control the opening/closing of a gate means, the burden of the microcomputer is lightened and it is not necessary to use a high-speed device.

Abstract: PROBLEM TO BE SOLVED: To automatically remove dust in a cartridge case to cope with dust on a discoid recording medium by providing a dust collecting part for collecting dust scattered by rotating the discoid recording medium in the cartridge case. SOLUTION: The dust collecting part 30 having a dust take-in hole 31 and a dust discharge hole 32 is provided on the outer side of a disk housing chamber 15 of the disk cartridge. The dust take-in hole 31 is formed to open in the direction opposite to the rotating direction as shown by an arrow of a magneto- optical disk housed in the disk housing chamber.
