Title: Detecting device for surface pressure distribution
Inventor: TAMORI TERUHIKO
IPC: G01L5/00
Filed: 1988-09-22
Abstract: PURPOSE:To detect a minute surface pressure distribution by forming a strain gauge element between the intersecting points of the 1st and 2nd scanning a electrodes consisting of plural electrodes arranged crossing each other and insulated from each other for formation of a matrix and therefore securing the connection between both scanning electrodes. CONSTITUTION:The X-direction scanning electrodes X1, X2... and the Y-direction scanning electrodes Y1, Y2, Y3... are arranged in a matrix via the spacer 103. Then the strain gauge elements 104 are formed with flexion by a vapor deposition process or the combination of the sputtering and etching processes with use of a Cu-Ni alloy material so that the elements 104 are set on the holes 101a of a blanked plate 101 and covers both types of scanning electrodes. The shape of the element 104 is decided so that the ratio between the width and the length (aspect ratio) of the element 104 is increased as much as possible. Thus, the surface pressure distribution applied to a pressure receiving plate is taken out as the electric signals by means of the change of the resistance value due to the flexion of the element 104 serving as the pressure receiving plate. Thus it is possible to detect the minute change of the pressure and a minute pressure distribution.

Title: Manufacture of siamese-type cylinder block
Inventor: EBISAWA SHIZUO
IPC: B22D19/08
Filed: 1984-11-09
Abstract: PURPOSE:To make thermal expansion around the circumference of a sleeve during running approximately uniform, and to restrict the gap between a piston and the sleeve in order to prevent the shortcircuiting of gas and the waste of oil by using a cast-iron sleeve heated and provided with a radially expanding force in a specific casting stage and boring it thereafter. CONSTITUTION:The deformation of each sleeve 3 caused by the filling pressure of a molten aluminum alloy is prevented by previously providing a radially expanding force to each sleeve 3. Further, when each sleeve 3 is preheated up to 150-700 deg.C, each sleeve 3 is heated by the molten metal approximately to the same temperature as that of the metal during casting to lower the rigidity of sleeve 3. By this operation, when the radially expanding force of each sleeve 3 is removed after solidifying the molten metal, each sleeve 3 lowered in its rigidity deforms so as to follow the cross-sectional shapes of cylinder barrels 11-14 after their shrinkages. The cross-sectional shape of each sleeve 3 is changed into a slightly elliptic shape parallel to the arranged direction of cylinder barrels 11-14. Accordingly, the residual casting stress is made approximately uniform around the circumference. Each sleeve 3 is subjected to boring work in this state, and the thermal expansion around the circumference of each sleeve 3 is made approximately uniform when an engine is driven after assembling.

Filed: 1990-09-05
Abstract: PURPOSE:To realize a desired focusing state while suppressing variance in distance measurement by narrowing down the starting focusing width of continuous distance measuring operation, and driving a lens and then resetting the focusing width wide. CONSTITUTION:A system controller 140 outputs the quantity of defocusing from a focusing position according to the signal of a focusing detection module 19 provided halfway between the right and left lens barrels of binoculars, and a motor 22 is driven by the quantity. When an automatic focusing switch, i.e. AF switch 16 is turned on, the focusing width is made minimum, distance measurement arithmetic is performed, and the lenses are driven. Then the focusing width is set again; when the switch 146 is continuously turned on, the distance measurement arithmetic is performed again, but the focusing width is the newly set value. Thus, highly accurate focusing is performed with the narrow focusing width in the beginning of continuous AF operation wherein the switch 146 is continuously turned on and then the wide focusing width is employed thereafter even if a camera-shake is made to suppress the variance in distance measurement.
