Abstract: PURPOSE:To measure a very narrow gap from the degree of control, by setting a polarizer into the optical path of the reflected light to separate the reflected light into two directions and then controlling the optical distance of the optical path so as to keep brightness to a constant degree for the interference light which is caused by the difference of the optical path. CONSTITUTION:A laser beam B0 radiated from a laser oscillator 23 transmits through a 1/2 wavelength plate 24 and is reflected by a beam splitter 25 to be made incident to a 1/4 wavelength plate 29. A laser beam B1, a part of the beam B0 made incident to the plate 29, is reflected; and a laser beam B2, another part of the beam B0, is reflected on the surface of a disk 36. The beam B1 is reflected at a beam splitter 26 and then reflected on a mirror surface 32 of an electrostrictive element 30 to reach a plarizing plate 34. The beam B2 reaches the plate 34 via the splitter 26, an electrostrictive element 31 and the splitter 26 again. Then the brightness is detected 35 for the interference light that transmits through the plate 34. A minute displacement is given to the surface 32 so as to set the output of detection 35 at a certain level. Thus a gap (h) is measured from the voltage which is applied to the element 30 at the moment when the minute displacement is given to the surface 32.

Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To fast perform overlap motion compensation that reduces discontinuous distortions between adjacent blocks caused by motion vector prediction by generating a weight coefficient matrix corresponding to a macroblock and performing overlap motion compensation prediction coding in a macroblock unit by using it. SOLUTION: It is identified whether or not a mode for performing overlap motion compensation is (S1901), and when it is not the mode, normal motion compensation is executed (S1902). Meanwhile, in the case four motion vectors exist in a macroblock when it is decided as a mode performing overlap motion compensation, overlap motion compensation processing in a general block unit is performed (S1904). In the case not four motion blocks but only one block exists, motion compensation processing is performed in a macroblock unit (S1905). Thus, it is possible to reduce the number of pixels to be accessed and the number of add operations.

Title: Dropper type constant voltage circuit
Inventor: WATANABE HARUO
IPC: G05F1/56
Filed: 1989-04-24
Abstract: PURPOSE:To prevent the variation of a drooping characteristic by providing a voltage dividing resister and first and second transistors TRs which have emitters connected to one end of an input power source and have bases connected in common and constitute a current mirror circuit. CONSTITUTION:An input supply voltage in is divided by resisters R6 and R7, and the collector current of a TR Q7 flows collector currents of TRs Q8 and Q9 constituting the current mirror circuit. The voltage across a resister R1 rises by this current; and when it exceeds a certain threshold, a TR Q3 is made conductive to quicken drooping of the output voltage, and the variation of the output characteristic due to the input voltage of the current for start of drooping is compensated. When an output terminal is short-circuited, the base potential of a PNP TR Q6 falls, and the TR Q6 is made conductive and TRs Q8 and Q9 are turned off, and the reduction rate of the output current is reduced at this time, and a residual current Is' is relatively large as shown in a figure with respect to the current curve. Thus, an influence of the input voltage variation of the output residual current is reduced even at the time of short-circuit.

IPC: B21B37/58
Filed: 1993-05-06
Abstract: PURPOSE:To secure stable strip passing property and shape quality by previously finding the difference of mill rigidity between the work side and drive side of a rolling roll and presetting the leveling of the roll gap of the mill. CONSTITUTION:A difference is made in mill rigidity between the work side and the drive side of the rolling roll, for example, when the mill rigidity on the work side is larger than that on the drive side, the roll gaps on both side are adjusted to the same SO as shown in (A) before the material is bitten in, the roll gap SWS on the work side becomes smaller than the roll gap SDS on the drive side as shown in (B) after the material is bitten in. Consequently, before the material is bitten in, the initial roll gap SOWS on the work side is adjusted previously to be larger as shown in (C) than an initial roll gap SODS on the drive side before the material is bitten. When the material is bitten in under this state, the roll gaps on both sides become equal as shown in (D).
