Title: Disk player
Inventor: SAWABE TAKAO
IPC: G11B19/28
Filed: 1988-02-04
Abstract: PURPOSE:To prevent the runway of a spindle motor from occurring and to shorten a recovery time even when a servo system is unlocked by controlling the motor with periodical sample and hold so as to always obtain a synchronization detecting signal from the reading signal of a disk. CONSTITUTION:A signal via an F/V4 is held at an S/H circuit 6 periodically from a frequency generator 3 which detects the speed of the spindle motor 2 by the command of a system controller 10. At the time of starting a system, when the output of a D/A conversion circuit 8 and that of a control signal generation circuit 11 are selected by changeover switches 7 and 12, a frequency servo loop is closed, and the motor is controlled so as to set the speed of the disk 1 at a speed corresponding to the output of the circuit 8. Therefore, it is possible to prevent the runaway of the motor from occurring even when focusing servo or spindle servo is unlocked due to a flaw on the disk, and to shorten the recovery time to maintain the speed at the one just before.

Filed: 1991-02-20
Abstract: PURPOSE:To obtain a surface acoustic wave filter which causes no spurious response and is excellent in signal selectivity by setting the logarithm of an IDT (interdigital electrode) finger and metallic conductor film thickness of an IDT and a reflector so as to suppress or avoid spuriousness caused by the vertical mode vibration of a resonator.

When one set of a positive polarity electrode finger 108 and a negative polarity electrode finger 109 of the IDT is counted as one pair to be M pairs, when M and film thickness, etc., are selected so that the total reflection coefficient of the IDT takes a prescribed value, as for the Q value of the surface acoustic wave resonator, a sufficiently high one is obtained. In this case, the logarithm M of the IDT finger is set to 80-150. In such a manner, an unnecessary signal is suppressed enough and a satisfactory filter characteristic can be realized.
