Title: Track access system for optical disk device
Inventor: ARAI SHIGERU
IPC: G11B21/10
Filed: 1987-03-20
Abstract: PURPOSE:To speedily jump tracks without any influence due to eccentricity of tracks by accessing a track in a mode of following up a virtual track position obtained by adding the extent of track eccentricity of time series stored in a memory and the extent of movement to a target position. CONSTITUTION:A track eccentricity signal (h) of time series outputted by a position detector 2 is stored in a storage circuit 3, and this output and the output of a computing element 6 are added by an adder 8 to generate a virtual track position signal (p). The virtual track position signal (p) is converted back to an analog signal by a D/A converter 9, and the difference from the track eccentricity signal (h) is operated by a subtractor 5 to obtain a following-up control signal C. Since intersections on an optical disk are converged on the virtual track position signal (p) if a tracking actuator 1 is so driven that the following-up control signal C is zero, a changeover switch 4 is switched to servo control at the time when the following-up control signal C is zero. Thus, the track jump is smoothly and quickly completed.

IPC: G03F7/20
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To avoid a leveling error in a scan type stepper by, at measuring flatness for examining an exposure focal point plane with a semiconductor substrate tilted, measuring the flatness of the semiconductor substrate for each measurement unit region whose area is that of an exposure unit region or less. SOLUTION: An exposure unit region has a horizontal length X mm and vertical length Y mm, while a measurement unit region is a region S21 having a horizontal length L1 mm which is a scanning direction for scan exposure and a vertical length L2 mm. LTV-measurement is performed for each measurement unit region S21 to determine a leveling reference plane for each measurement unit region S21, and the measurement unit region is sequentially shifted from S21a to S21b, and then to S21c for measurement likewise, determining a leveling reference plane. Related to shifting of measurement unit region, the measurement unit regions S21a and S21b, for example, as well as S21b and S21c, are performed to overlap by at least 1/2 of horizontal length. Thus, a high-precision leveling control is provided.

Title: Optical measuring method for minute gap
Inventor: TERAJIMA SEIICHIROU
IPC: G01B11/14
Filed: 1982-04-23
Abstract: PURPOSE:To measure a minute gap quickly and highly accurately, by detecting the position of a deark part or bright part of interference fringes formed in a photoelectric transducer part 8, and obtaining the gaps between two bodies from said position. CONSTITUTION:A dark part of interference fringes is generated in gaps h1 and h2 between a disk 5 and a slider 6 and picked up by a photoelectric transducer part. A signal corresponding to brightness is obtained by scanning said interference fringes. X and Y directions are determined, and a voltage in the Y direction is fixed to VR. Then the entire width in the X direction is scanned, and a signal 7 is obtained. V1 and V2 are obtained from scanning voltages V0, Vh1, and Vh2 corresponding to the dark part of the brightness signal. Thus the minimum value of the gap can be determined.

Title: Method for transplanting colony
Inventor: KADOKURA ISAO
IPC: C12N1/00
Filed: 1986-03-26
Abstract: PURPOSE:To make it possible to distinguish a starting point of colony transplanting from the end point, by transplanting colonies to a profile shape formed by aggregate of transplanting points of colony in such a way that a specific part is made. CONSTITUTION:In transplanting several colonies to a medium in a laboratory dish, the colonies are transplanted to a profile shape formed by aggregate of transplanting points of colony in such a way that a straight-line side part having length different from those of other sides is made at least at one spot in order to clarify direction of transplanting. By this method for transplanting colonies, the profile shape formed by the aggregate of transplanting points of colony is not point of symmetry. Consequently, in transplanting the colonies to the medium in the laboratory dish, a spot from which transplanting is started and a spot where transplanting is completed are instantly distinguishable. Therefore, even if the laboratory dish may be treated somewhat roughly, the starting point and the end point of transplanting are almost always distinguishable.
