Title: Irregularity measurement of semiconductor wafer surface
Inventor: NAKAJIMA KEIJI
IPC: G01N21/956
Filed: 1990-04-27
Abstract: PURPOSE:To measure irregularity shape easily with non-destructive measurement by forming a pattern on a semiconductor wafer and selecting respective points on each boundary line between the pattern and a measured film as the points corresponding to images in each direction of different visual lines and then, obtaining a profile of the boundary line. CONSTITUTION:Measurement is performed by using a sample which forms a pattern 6 on a semiconductor wafer 2. Images on the surface of a semiconductor wafer are obtained with a detector 4 (a visual direction V is constant) by rotating a sample plate 3 only at each angle of theta and phi after placing the semiconductor wafer 2 on the sample plate although parallax takes place by the rotation of the sample plate. Further, in an image processing device 5, boundary lines (edges 1 and 2) are extracted from the images that are rotated at each angle of theta and phi obtained by the detector 4. Then a profile of each boundary line is obtained with a trigonometrical survey to measure irregularity shape by making respective points on the edges 1 and 2 have one to one correspondence to each image.

Filed: 1989-05-02
Abstract: PURPOSE: To prevent chalk blocks from loosing out and make it convenient to use by providing a housing to hold a chalk block, a first and a second openings enabling top of a billiard cue to touch the chalk block and a fixture to hold the housing. CONSTITUTION: A chalk block 28 is put into the hollow 26 of a housing 12 to completely fill it. On the chalk block 28 are processed several dimples 29, some of which facing an opening 14 while others facing another opening 16 in the edge wall 32. A holder 38 is put in through openings 36 in the flange 34 and 40 and the housing 12 is horizontally put onto its flat face. As the top 44 of the cue 42 is put through either the opening 14 or 16 in the edge walls 30, 32 of the housing 12, it catches chalk when the cue 42 is rotated by touching the chalk block 28 on very edge. When one chalk block 28 on very edge is used up and finished, next one comes on to a position to apply chalk on the top 44 of the cue so as to ensure continuous use.

Title: Ultrasonic 3d torque resonator and actuator
Inventor: KUMADA AKIO
IPC: B06B1/06
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To enable developing a revolution torque having a component perpen dicular to the diameter in an electrostrictive revolution element by two- dimensionally moving each part of the element while the path swept by it is described as circle in a resonant state of an electrostrictive revolution element. SOLUTION: A quarter of a central circumference λ, 1/4λ, is selected as the length in the center axis direction of an electrostrictive revolution element 1. When the electrostrictive revolution element 1 is excited at a frequency f1 =1.5f0 resonant with it, a strong revolution torque is generated on the end surface of the circumference of the electrostrictive revolution element 1. As a result, when a rotor 9 fitted with a rotating shaft 10 at the center thereof is abutted on the end surface of the cylinder, the rotor 9 is strongly rotated whether the supporting direction of the shaft 10 is parallel to a diameter 3, perpendicular to it, or the arbitrary one.  Next, when the abutted surface of the rotor 9 is changed from the end surface to the inner and outer peripheral surfaces, a rotation torque is obtained in the arbitrary supporting direction similarly to the end surface, and a 3D revolution torque is generated.
