IPC: G11B7/085
Filed: 1989-04-05
Abstract: PURPOSE:To accomplish high speed access with high accuracy by providing 1st and 2nd hold circuits which hold output from 1st and 2nd phase compensation circuits when a follow-up action is not performed by a beam spot. CONSTITUTION:A detector 101 detects a track error signal showing the relative positional deviation between the beam spot and a track. In order to stabilize the action of a tracking actuator 102, the phase compensation circuit 104 performs phase compensation to the track error signal, and the phase compensation circuit 105 performs the phase compensation to the track error signal in order to stabilize the action of a linear motor which drives an optical head. The hold circuit 106 holds the output from the phase compensation circuit 105 when the follow-up action is not performed by the beam spot at the time of controlling the access, and the hold circuit 107 holds the output from the phase compensation circuit 104 when the follow-up action is not performed by the beam spot at the time of controlling the access. Thus, access with accuracy is performed.

Abstract: PURPOSE:To instantaneously decide whether a subject blinks at the time of a measurement or not and to execute the correct decision by detecting the blink from the boundary position of the pupil of an eye to be examined based on the video signal of a photodetector. CONSTITUTION:A light source 4 image is projected to an eye ground 7 of the eye to be examined, a reflected luminus flux 10 from the eye ground 7 of the eye to be examined is light-received by a photodetector 9 arranged in the approximately conjugated position with the pupil of the eye to be examined, and the eye refracting power of an eye 3 to be examined is measured by the received luminus flux. The blink is detected from the boundary position of a pupil 6 of the eye to be examined based on the video signal of the photodetector 9. Namely, a light quantity distribution on a line to pass a luminescence spot formed by a cornea reflected luminus flux is obtained, the boundary position is detected from two points in which the light quantity changes are remarkable in the light quantity distribution, and the blink is detected by the fluctuation of the boundary position. As a result, whether the subject blinks at the time of the measurement or not can be instantaneously decided, and moreover, the correct decision without an artificial error in the decision of the blink can be executed.

Abstract: PROBLEM TO BE SOLVED: To improve its accuracy by previously deforming a mask, correcting only a feature important for one, and removing generation of the additional apex as many as possible in VLSI pattern transfer operation such as photolithography and reactive ion etching(RIE). SOLUTION: This optical proximity correcting(OPC) method breaks down complicated computer aided design(CAD) data for a lithographic mask or a reticle into a basic quadrangular combination by using a series of reducing, enlarging and subtracting operations. In more detail, this OPC method discriminates plural gate areas in CAD design in the first place. Plural design shapes in the CAD design are sorted according to a geometric type. The sorted plural design shapes have at least one side in common with a second design shape. The sorted design shapes are grouped with its rear width as a reference. Lately, they are discriminated as gate areas, and all the grouped design shapes are corrected according to an applicable OPC rule.

Abstract: PURPOSE:To increase a storage density by setting the peak height of the ruggedness on a magnetic disk surface lower from the inner peripheral side toward the outer peripheral side and specifying the max. peak height of the ruggedness of the respective zones of data. CONSTITUTION:A glass substrate 1 is mounted at a spindle 2 and is rotated by this spindle. A gaseous mixture contg. hydrogen fluoride in an inert gas is blown to the substrate 1 from a nozzle 3 set in the upper part on the inner peripheral side of the substrate 1 to etch the surface and to form the surface ruggedness. The blown gaseous mixture is blown off from the inner peripheral part toward the outer peripheral part, by which the concn. thereof is made thinner in the outer peripheral part than in the inner peripheral part. The peak height of the ruggedness is higher as the canon. of the gaseous mixture is higher and, therefore, the peak height lowers successively from the inner peripheral side toward the outer peripheral part. The max. peak height of respective set of the ruggedness in the outermost peripheral part of the CSS zone and the innermost peripheral part of the data zone is specified by controlling the concn. of the gaseous mixture in a radial direction, by which the ruggedness is formed. As a result, the flying stability and lower floating of the head are made possible and the storage density is increased.

A first counter 5 steps by the output signal of an AND circuit 5, and a second counter 6 steps by a clock pulse Cp of constant cycle. A control circuit 7 fetches the coefficient value lk of the counter 5 and the calculation value lp of the counter 6 at every constant time, and after a computed value A(lk/lp) exceeds a reference value Aup set in advance, a new call connection to a corresponding output line is refused, and when the computed value A becomes less than the reference value Adw, the new call connection to the corresponding output line is restarted. In such a way, it is possible to keep the scrapping rate of the packet under the targeted value even when a packet arrival pattern is fluctuated.
