Title: Pattern inspection
Inventor: TSUZUYAMA BUNJIROU
IPC: G03F1/84
Filed: 1978-10-16
Abstract: PURPOSE: To perform inspection accurately, by placing a pattern to be inspected on a support whose movement is controlled by a calculator, illuminating the pattern instantaneously, catching the reflected light by means of a pickup tube, and inspecting the shape and position of the pattern.  
     CONSTITUTION: Pattern 1 to be inspected, which has pattern region A to be inspected, is mounted on support 3. Support 3 is moved by drive mechanism 2, which is controlled by calculator 6. Position signal generator 5, constructed of a laser interferometer, is placed in the neighborhood of support 3. The amount of movement of support 3 is fed back to calculator 6. Illuminator 6, which is controlled by calculator 6, is placed diagonally above pattern 1 to be inspected. At each movement of support 3, instantaneous illumination is done. Pickup tube 8, which picks up the picture signal of pattern region A, is placed above pattern 1. The output signal from here is sent, via binary converter 11, to shift register row 12, pattern shape detector 21 and pattern position detector 31, and thereby the shape of region A is detected.

Title: Inter-object distance computing unit and inter-object distance computing program storage medium
Inventor: SATO YUICHI
IPC: G06F17/50
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To calculate the distance between two convex objects at a high speed by providing a first closest approach vector computing means for obtaining a closest approach vector and a second closest approach vector computing means for correcting the closest approach vector. SOLUTION: A closest approach vector obtained in the first closest approach vector computing means 15 is the closest approach vector when both objects are regarded to be convex polyhedrons and is the closest approach vector of insufficient precision for a convex curved surface object. The closest approach vector obtained in such a manner is inputted to the second closest approach vector computing means 16 along with the shape information (including curved surface batch information) of the two convex objects to be the object.  In the second closest approach vector computing means 16, based on the principle that a plane in contact with a convex curved surface object and the closest approach vector for connecting the closest approach points of the two convex objects with each other are orthogonal at the closest approach point of the convex curved surface object, the obtained closest approach vector is corrected to the new closest approach vector of high precision further.

Title: Vibrator type moisture sensor
Inventor: SUGAWARA TOORU
IPC: G01N27/00
Filed: 1980-09-19
Abstract: PURPOSE:To make a moisture sensitive polymer hard to peel under moisture absorption and desorption by arranging a porous on the surface of a vibrator so that it is impregnated with the polymer. CONSTITUTION:The frequency of a vibrator 1 made of barium titanate, lead titan- zirconate, quartz crystal or the like is determined by material, shape and dimensions. A porous material impregnated with a moisture sensitive polymer is preferably the same in the material as the vibrator. The vibrator 1 is supported on a support base 6 and a thin film electrode 2 made of gold or the like is connected to a connection terminal 5 with a lead with 4 while the vibrator 1 is connected to a part of an oscillation circuit 7. An output terminal 8 provides an output corresponding to the resonance frequency of the vibrator. When the vibrator 1 is placed in a measuring atmosphere, moisture is absorbed with the moisture sensitive polymer to increase weight and the resonance frequency of the vibrator 1 varies thereby allowing the detection of relative humidity. As a thin porous material is impregnated with a moisture-sensitive polymer, peeling is made so hard to occur to ensure stability for a long time.
