Title: Access control circuit
Inventor: SASAMA MASASHI
IPC: G11B19/20
Filed: 1983-03-28
Abstract: PURPOSE:To detect the runaway of a head moving means and to prevent a magnetic disc and a head from being damaged by integrating current flowing into a voice coil motor (VCM) in a head moving means and monitoring the output. CONSTITUTION:A real speed detecting circuit 1 detects the moving speed of the head. A speed instruction generating circuit 2 generates a head moving speed under control from the host device. An operational amplifier 3 comares a signal from the speed detecting circuit 1 with a signal from the speed instrction generating circuit 2 and outputs the difference. Receiving the signal from the operational amplifier 3, a power amplifier 4 makes current flow into a VCM5. When the output signal of the real speed detecting circuit 1 exceeds a set value i.e. the runaway state is generated, a real speed detection type runaway detecting circuit 6 turns off the power amplifier 4 and interrupts current supply to the VCM5. A current integration type runaway detecting circuit 7 integrates the current flowing into the VCM5, and when the integrated value exceeds a set value, turns off the power amplifier 4 and interrupts current supply to the VCM5.

Filed: 1988-03-03
Abstract: PURPOSE:To drastically reduce the number of signal lines to link respective processors and an interleaving control circuit by outputting the communication signal of the accessible bank from an interleaving control circuit to respective processors. CONSTITUTION:Plural processors 10-1,...,10-n make access to respective banks of an interleaving memory 14 under the control of an interleaving control circuit 16 in accordance with a priority by a common bus 12. An access requesting means 18, when an access request for the bank in which it is confirmed that the access can be executed by the informing signal of the circuit 16 occurs, outputs an access requesting signal for the bank to the processors 10-1,...,10-n with the low priority of a bank access and the circuit 16. An access starting control means 20, when other processors 10-1,...,10-n with the high priority for the bank to generate the access request do not request the access, executes the starting control of the access the said bank.

Title: Synchronous controller
Inventor: YONEDA TAKAO
IPC: H02P5/46
Filed: 1989-03-02
Abstract: PURPOSE:To stabilize a feedback system on a shaft by providing a pause time of a predetermined period time after a correction value is varied, and calculating a next correction value after the unstable state of the system of the shaft due to a correction is converged. CONSTITUTION:In a calculation for a correction value for correcting the step-out amounts of left and right main shafts 18, 19, the calculation and updating of the correction value are conducted at a predetermined time interval. Since the updating of the correction value is executed at each predetermined period time longer than the unstable time of the feedback system of the shaft, the correction value is calculated based on the step-out amount in a state that the feedback system of a right main shaft motor 21 is stabilized, and next correction value is added. Thus, when the system is unstable, the correction value is not further added to prevent hunting of the shafts 18, 19, thereby shortening. a period of time until it is stabilized.
