Patent CA-2014172-A1 (CA)
IPC: G11B7/095
Filed: 1990-04-09
Abstract: A track access control system in a rotating disc storage device including: a data writing/reading head which is movable in a radial direction of a rotating disc; and an impinging beam moving mechanism is mounted on the data writing/reading head, for moving am impinging position of the optical beam for the data writing/reading, on the data writing/reading head. A relative position of the impinging beam on the disc from an optimum position is detected. The position of the head is controlled responding to a low frequency component of the above detected deviation, and the operation of the impinging beam moving mechanism is controlled responding to a high frequency component of the above detected deviation, so that the deviation is reduced during a track servo operation. A waveform memorizing circuit records a waveform of the movement of the head during a track servo operation. A track jump control mechanism moves the head and the above relative position of the impinging beam so that the position of the impinging beam moves to a requested track. During the track jump operation, control quantities to move the head and the above relative position of the impinging beam is modified by adding the above recorded data of the waveform memorizing circuit thereto, corresponding to a current rotation angle of the disc. Further, when an erasing beam outputting unit is mounted on the head, a displacement of an outputting position of the erasing beam on the head from a predetermined position, is memorized during a track servo operation, and is added in the above modification during the track jump operation.

IPC: H01H13/64
Filed: 1990-04-23
Abstract: ABSTRACT OF THE DISCLOSURE    A method and an apparatus for preventing erroneous operation in a non-contact push-button switch.    This method is to impress pulse power on a non-contact switch, to discriminate good or bad of the output signal from the switch and to give selectively an operation signal to a driving circuit.  Even if an operation output is given from the switch, while the push-button is in OFF state due to trouble of electronic parts constituting a non-contact push-button, no signal which means operation is given from the discrimination circuit and accordingly the OFF state is maintained and unreasonable working of the apparatus or other trouble does not take place.

Abstract: CHUCK MECHANISM FOR DETACHABLY CONNECTING IMPELLER SHAFT AND DRIVE UNIT OF MIXING APPARATUS                       Abstract Chuck mechanisms are described which quickly connect and enable quick disconnection of an impeller shaft of a mixer from the drive shaft of the motor unit. The motor unit drives a spindle having a central opening which receives the shaft.  The spindle has a keyway which enables a key, either a detent key which is movable in the keyway or a key which is provided by pins extending from the shaft, to be aligned in locking position where the key transfers the thrust from the spindle to the shaft or an unlocked position where the shaft is rotated out of the locking position and may be removed from the spindle.  The detent key is adapted to be captured by an elastic O-ring and is reciprocated outwardly by the shaft when it is turned from locking position to unlocked position where a flat on the shaft in a groove which receives the detent key is rotated away from the key.  The key is retained in locking position by an outer sleeve or collar having a slot which enables the key to move away from the shaft when the shaft is rotated to the unlocked position.  When the collar is rotated to move the slot away from the key, the key is locked against outward movement.  The keyway may be sufficiently large to enable the flat on the shaft to tilt the key so as to provide wedging action of the key against the spindle sleeve and tighten the shaft on the sleeve so as to preclude slipping when greater torque is needed by the mixing impeller.  In another embodiment, a tapered bolt is used in a cross-bore through the spindle sleeve, which bolt and a flat with a cylindrical undercut define a keyway.  A tapered shoulder portion of a bolt which extends into the keyway defines a guide which permits the shaft to be inserted only with the flat in alignment with the cross-bore and keys the sleeve to the shaft when the bolt is screwed into the cross-bore.
