Title: Polishing device for notch section of wafer
Inventor: HASEGAWA FUMIHIKO
IPC: B24B21/22
Filed: 1993-10-29
Abstract: PURPOSE:To efficiently polish the notch section of a wafer by providing a fluid blowing means which blows fluid against the back face of a tape so as to press the surface of the tape onto the inner surface of the notch section, and providing a vibration imparting means which vibrates the tape in its width direction. CONSTITUTION:A wafer W is absorbed on the absorbing section of a wafer holding mechanism in advance, and the absorbing section and a polishing section 3 approach to each other. Fluid is then blown off out of the fluid blowing-off nozzle 11a of a fluid blowing means 11, and a tape 4 is pressed on the inner surface of the notch section 1 of the wafer W. Moreover, a take-up reel 6 is rotated by a motor 13, and concurrently guide rollers 8 and 9 are vibrated in the axial direction by a vibration imparting means. The surface of the tape is then tilted with respect to the surface of the wafer by a tilting means, so that polishing is thereby performed. In this case, since no free abrasive grain is used, the wafer will never be stained.

Title: Electron source apparatus using photoelectric plane
Inventor: KINOSHITA KATSUYUKI
IPC: H01J37/075
Filed: 1989-11-13
Abstract: PURPOSE:To maintain high vacuum condition easily by forming a minimum small hole necessary for reaching a photoelectron accepting chamber, an exhaust hole to exhaust gas from a photoelectron accepting chamber, and a second exhaust hole to exhaust gas from a photoelectric plane storage chamber so as to set this chamber in higher vacuum condition than at in the photoelectron accepting chamber independently of the former exhaust hole. CONSTITUTION:A small hole 20 having the minimum diameter for passing a photoelectron beam is formed in a partition 18 and a photoelectric plane storage chamber 14 and a photoelectron accepting chamber 16 are evacuated by separately provided vacuum, pumps 22A 24A through exhaust holes 22, 24 so as to maintain higher vacuum condition in the photoelectric plane storage chamber 14. Alkali atoms are thus suppressed to move from the photoelectric plane storage chamber 14 to a photoelectron accepting chamber 16 and the photoelectric plane storage chamber 14 which is small, can be kept in vacuum condition higher than that of the photoelectron accepting chamber 16. In this way high vacuum condition is easily maintained and deterioration of the photoelectric plane is suppressed and an alkali atoms are prevented from transferring.

Title: Video camera jiggle correction circuit
Inventor: IINUMA TOSHIYA
IPC: H04N5/232
Filed: 1991-11-11
Abstract: PURPOSE:To prevent the misdetection of the video camera jiggle caused by the transient characteristic of a horizontal or vertical filter. CONSTITUTION:The digitization outputs of the input video signals obtained in a photographing area are successively inputted to a horizontal filter 2 and a vertical filter 3 and then inputted to a key point storage means 5 and a block- based correlation detector means 6 with band limitation. The means 5 stores the filter output at a fixed key point corresponding to a detection area which displaces in the areas except the transient areas of both filters 2 and 3. The meant 6 compares the filter output of each detection area and the storage data on a fixed point to obtain the difference absolute value. These absolute values are cumulatively added together at the same position of the detection area in a common detection block. Thus a block-based correction vector is obtained. Based on this vector, a differential vector is obtained. Then the position of the detection area is set based on the differential vector for the next field.

IPC: H01S5/068
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To restrain signal fluctuation without performing recognition regeneration on an electric stage, by converting an optical signal which is intensity- modulated by a digital signal into an electric signal having the state of signs corresponding to ON OFF, and inputting the signal of the form that the signs of the electric signal are inverted via a converting means, in a semiconductor laser in the state of oscillation. SOLUTION: A signal light IM which is intensity-modulated by a digital signal is inputted in a photoelectric converting means 11, which outputs an electric signal whose voltage is -Vm and +Vm corresponding to ON and OFF of the signal light IM. A modulation means 12 adds the electric signal and the bias voltage Vb of a semiconductor laser 13, and converts the electric signal into an electric signal E whose voltage is (Vb-Vm) or (Vb+Vm) when the signal light IM is ON or OFF, respectively. The modulation means 12 applies the electric signal E to the anode side of the semiconductor laser 13. The laser oscillation turns off when the signal light IM is ON, and turns on when the signal light IM is OFF, so that a signal light IM' which is complementarily modulated to the signal light IM is outputted.
