Title: Method and system for measuring surface shape of body using large equivalent wavelength
Inventor: PIITA DE GURUUTO
IPC: G01B11/30
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To accurately measure a surface shape with a wide visual field and a high scanning accuracy by applying light to a desensitizing interferometer with a longer related equivalent wavelength than a light-source-related wavelength by a light source with a related wavelength to obtain desensitizing interference fringes. SOLUTION: Light from a light source 30 is focused at application rays 140 by a lens 35. The rays 140 are first divided into rays 150 and 160 by a diffraction grating 120. Then, the rays 150 and 160 are diffracted by a diffraction grating 130 and hit against an object 20. An equivalent coherence length is related to the degree of unevenness on the surface of the object 20 and the application area of the light source 30 and the equivalent coherence length can be adjusted when the degree of space coherence of the light source can be changed. The reflection light from the object 20 enters an interference grating 130 again and is diffracted so tint it is synthesized again on the surface of the diffracting grating 120.  The resynthesized rays are diffracted by common emission rays 180 and are focused on a camera 50, thus detecting an interference pattern for indicating the difference in the optical path length of the rays 150 and 160.

Abstract: PROBLEM TO BE SOLVED: To permit a free access to a mold region and to efficiently compensate the strain of a frame in the clamp falling of mold halves by separating first and second structural members in an adjustable manner along the first common surface spaced apart from a mold centerline. SOLUTION: In the generation of clamp operation between mold halves 12, 14, force is applied to structural members 18, 24 and pushed to the clamp heads 30, 32 of a tension member 26 to extend the tension member 26. Since the moment generated by the clamp operation is set off, a movable and adjustable compression system 27 is used for moving the bottom portions of the structural members 18, 24 outwardly by the quantity substantially equal to the sum total wherein the bending strain of the structural members 18, 24 is added to the extension of the tension member. The compression system 27 causes the separation of the first and second structural members. By this constitution, the strain of a frame is compensated.

Title: Dog gear tooth shape of transmission
Inventor: MAEDA TAKESHI
IPC: F16H3/12
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To improve allowable input load of a dog gear tooth without decreasing the tooth depth by forming cut recessed parts on both right and left sides of the tip in the range of the tooth height and decreasing the height of the acting tooth depth by the depth of the cut recessed part. SOLUTION: In a dog gear tooth 3, cut recessed parts 6 are formed on both right and left sides of the tip in the range of the height (h) of the tooth, the height of the acting tooth depth (b) is decreased by the height (a) of the cut recessed part 6, and the width (c) of the tip is smaller than the width of the tooth surfaces 7 on both sides of the height part of the tooth depth. Since the dog gear tooth has the above-mentioned shape, load is not applied to the recessed parts 6 on the tip, and the part to which load F is to be applied can be substantially lowered in the height (f) range of the tooth. Therefore, allowable input load of the dog gear tooth 3 can be improved without decreasing the outside diameter of the dog gear tooth 3, and a problem of controllability of a transmission and the side effect in which the gear slips off can be eliminated.
