Inventor: OGURO TAKAHIRO
IPC: G01B21/16
Filed: 1991-12-27
Abstract: PURPOSE:To obtain the accuracy measuring apparatus for an analogously-shaped structure for measuring the shape of the grooves of a fin structure simply in a short time it relatively high accuracy. CONSTITUTION:A gage 2, which has many fins at the same pitch, is provided so that the fins are intermeshed to each other with all groove parts of a fin structure to be measured 1. The errors in groove widths, the errors in groove pitch and the errors in inclinations of the grooves are collectively measured based on the amount of displacement caused by reciprocating any of the fin structure to be measured 1 or the gage 2 into the right and left directions orthogonal to the fins. The machining accuracy after the machining of the grooves of the fin structure can be measured in a short time in relatively high accuracy by the simple reciprocating operation of any of the material to be measured or the gage.

Title: Circuit for stabilizing camera-shake
Inventor: KOU JIYONGEN
IPC: H04N5/243
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To improve the correction precision by reading a defected part of a profile of a video image caused when an input video signal is corrected from a buffer and synthesizing the images so as to obtain a final video image thereby eliminating the deterioration in the resolution in a magnified video image. SOLUTION: A video image motion detection section 62 detects a motion vector from an input video image from an image pickup element 61 and a video correction section 63 corrects the input video image stored in a 2nd buffer 66 based on a motion vector given to the detection section 62. A video synthesis section 65 synthesizes the defected video image in the corrected video image by selecting the video image from a 1st buffer 64 storing the current video image for synthesis between the input video image of a preceding field and the video image of a succeeding field. Thus, the video input is corrected by a hand-shake component of the video image detected already.  The video defect images of two sizes at maximum among four sides (upper/lower/left/right) caused in the video image correction are corrected by reading the video information of a delayed field stored in the buffer 64 to synthesize the final image.

Title: Production of magnesium fluoride
Inventor: TANAKA TADASHI
IPC: C01F5/28
Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To obtain powder which has good filtering property for slurry and which is fine without causing aggregation by adding a magnesium salt to hydrofluoric acid at a specified or lower temp. to react and controlling the slurry concn. to a specified value or lower when the reaction is completed. SOLUTION: A magnesium salt is added to hydrofluoric acid to control the liquid in the initial reaction stage to strong acidity. Since nuclei are produced and grown and grains are grown in an oversaturated region, the filtering property of the slurry is improved. The slurry concn. is preferably <=14% when the reaction is completed, and desirably 8 to 12%. The reaction temp. is preferably <=60 deg.C, and desirably 20 to 50 deg.C. The magnesium salt is prepared by refining a soluble magnesium salt such as magnesium chloride by recrystallization. Because the obtd. reaction slurry gradually gels, the solid liquid separation is fast carried out. Since the reaction slurry is acidic, it may be neutralized with ammonia or the like and then subjected to the liquid solid separation.  The cake obtd. by solid liquid separation and cleaning is dried to obtain white magnesium fluoride fine powder without aggregation.
