Title: Method and mechanism for controlling sweep seek of magnetic disk device
Inventor: TAKEUCHI TOSHIO
IPC: G11B21/08
Filed: 1989-03-03
Abstract: PURPOSE:To perform sweep seek at high speed and in a short time by performing movement to an inner guard band and an outer guard band by direct seek used on an ordinary data plane. CONSTITUTION:When no microprocessor control circuit group 10 is selected by a host device, the sweep seek to return a head to an original cylinder is performed after the head is sought periodically from the inner guard band to the outer guard band. To perform the above operation, a counter 112 to decide the start of the operation, a judging part 111 to decide the sweep seek based on the states of a counter set signal and an interface signal, a register 107 in which a guard band cylinder is stored, a buffer 102 to hold a called guard band cylinder, and a selector 103 to select the cylinder of ordinary seek or a sweep cylinder are provided. Also, positioning for constant time on the guard band cylinder can be realized by providing a timer 110. In such a way, the sweep seek can be performed in a short time and also, at high speed.

Title: Zero cross synchronizing signal generating circuit
Inventor: ASOU TADASHI
IPC: H03K6/00
Filed: 1981-04-09
Abstract: PURPOSE:To obtain a zero cross synchronizing signal having a small shift of phase with a simple constitution of circuit, by giving the single-phase full wave rectification to the input AC voltage, supplying the rectified voltage to a filter circuit and supplying the output of the filter circuit to a voltage comparator. CONSTITUTION:A single-phase full wave rectifying circuit 2 supplies the AC voltage Vin and delivers the full wave rectified voltage VR. A BPF3 supplies the voltage VR and delivers the AC voltage Vf having a frequency twice as high as the basic frequency of the voltage Vin. This output waveform is identical with a waveform in which the zero cross point of one side is substantially coincident with that of the basic wave of the voltage Vin. Thus a zero cross period pulse signal Vout which has a rise synchronously with the zero cross point of the basic wave of the voltage Vin with about 50% duty ratio is obtained by supplying the voltage Vf to the other terminal of a voltage comparator 4 having the reference voltage of OV. As a result, a phase compensating circuit is eliminated.

Similarly, the duplicated reading range A on the original is read by an infrared ray image pickup element 5c and becomes a range A1. A microcomputer 14 inputs the range A1 and performs a prescribed operation A2(alpha/beta)XA1. Then, the picture information is outputted in the order of address from the memory 12 by a control signal of the microcomputer 14 and the picture information is outputted from the memory 13, and the control signal of the microcomputer 14 neglects the address component corresponding to the range A2 obtained from the result of operation and outputs the picture information in order from the next address. The picture information outputted in this way is the required information without duplicate reading.
