Title: Turning device by utilizing variable pump
Inventor: KAWAGUCHI AKIHISA
IPC: F04B49/00
Filed: 1978-12-11
Abstract: PURPOSE: To ease a shock when turn starting, as well as improve a fine control characteristic, by providing in the variable delivery pump a control device for varying a delivery amount of the pump inversely proportionally to its delivery pressure.  
     CONSTITUTION: In variable delivery pumps 1W3, is provided a control device 4 for varying a delivery amount of the pump inversely proportonally to its deliverly pressure. In this way, when turn starting, with a pressure going up to the set pressure of a relief valve 17 by an external inertia force, resistance, etc., the deliverly amount of the variable delivery pump 1 is set to a minimum level by the control device 4, and a hydraulic motor 5 begins operating with a few amount of shock at high pressure with low flow rate. And in a control range of fine flow rate of a changeover valve 6, the delivery amount of the variable delivery pump 1 is reduced to the fed to the downstream hydraulic motor 5, causing a pressure to rise in the upstream side of the changeover valve 6, and the delivery amount of the variable delivery pump 1 is reduced by the control device 4. Accordingly, the fine control characteristic can be improved.

Inventor: YAMAGISHI MASAKATSU
IPC: G01L5/00
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To estimate an impact force without the need of striking an object by calculating the impact force according to plural accelerations of a striking action detected before the last time when acceleration polarity is reverse prior to the detection of absolute value maximum acceleration. SOLUTION: Once a measured person conducts the striking action with the dextral hand wearing a watch body, the acceleration data at intervals of 0.01 seconds by an acceleration sensor 12 is stored by RAM 20 through an A/D converter circuit 14. Simultaneously prior to the time of its absolute value maximum, data of 20 points P1 -P20 immediately before the hit point H when the acceleration data value is inverted lastly is extracted, and the converted acceleration data X1 -X20 is stored in the RAM 20. If a striking of the measure person is karate, for example, impact force is calculated on the basis of weighting factors a1 -a20 and a constant C1 for the acceleration data X1 -X20 stored in the RAM 20 and the acceleration data X1 -X20 previously stored in the data storage part for karate in ROM 19 by the expression of the impact force (karate) = a1 .X1 +...+a20 .X20 +C1 .  The calculation result is stored in the RAM 20 and displayed on a display part 22.

Title: Reader of different types of forms
Inventor: TATEYAMA HIROMI
IPC: G06K9/32
Filed: 1983-08-23
Abstract: PURPOSE:To read the OCR forms of a form discriminating area at an optional row position by feeding an image with the smallest distance of a set form discriminating area and repeating the primary and secondary corrections for recognition to detect a form discrimination code. CONSTITUTION:A form is positioned by a start position deciding circuit A and based on the input conditions LL (the minimum distance between the upper end of the form and a form discrimination area) so that the corresponding image is set at the center of a line buffer. Then the form is fed through an image input part B. A black part is checked by a black part detecting circuit C, and a character detecting circuit D discriminates the black part, if detected, whether it is equal to characters or not. In case no character is decided, the form is shifted by LT/2 (1/2 vertical length of the line buffer) by a secondary correction circuit G and then sent back to the part B. Then the 2nd image is fed to repeat the code recognition. When characters are decided, the form is shifted by a primary correction circuit E so that the upper end distance is set at the fixed value epsilon. Then the characters are recognized by a character recognizing circuit F. The detection is over when the form code is decided.

Filed: 1979-11-30
Abstract: PURPOSE:To enlarge the life of a quartz glass plate to be used for the manufacture of semiconductor by a method wherein the surface of the quartz glass plate is so formed as to have the length from the end faces to be less than 20mm., and to have the difference between the maximum and the minimum roughness per measured length of 3mm. to be 30mum or less. CONSTITUTION:When the quartz glass plate before use has previously a minute crack, the crack grows and is enlarged still more by the stress acting to the glass during use. Therefore the surface within the range less than 20mm. from the edge is polished to make to be smooth. When the length exceeds 20mm., it is not economical. The roughness of the polished surface is so made as the difference between the maximum and the minimum per 3mm. to be 30mum or less. When it exceeds 30mum, the number of times to be usable is reduced. The roughness is measured with a surface roughness measuring apparatus, and the roughness between the maximum and the minimum is obtained from the height of chart. Besides the polishing, to melt the unevenness with an oxyhydrogen gas burner after rough polishing to form a smooth surface may do. By this constitution, even if the quartz glass plate is used repeatedly, the crack does not generated and the life is prolonged.
