IPC: G01L19/00
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To provide a pressure detection element that is not affected by a conductive deposit and a pressure sensor using the pressure detection element. SOLUTION: In a pressure detection element 30, a substrate 31 and a substrate 32 are fixed each other via a spacer 33, and the substrate 31 and the substrate 32 are constituted so that capacitance is generated between a fixed electrode 35 and a movable electrode 36 being formed on surfaces that oppose each other in parallel.

In the pressure detection element 30, a shield electrode 37 is formed at a part of the reverse side of the substrate 32 where pressure is applied.  Therefore, even if a foreign object 39 enters from a device to be measured and adheres to the surface of the shield electrode 37, the level of a floating capacity does not change greatly, thus eliminating the influence of the foreign object 39 to pressure measurement.

Abstract: PURPOSE: To obtain an olefin/vinyl acetate copolymer hydrolyzate which is stable against heat, resistant to discoloration and easy to heat-mold, by adding a specific amount of acetic acid and sodium acetate to an olefin/vinyl acetate copolymer hydrolyzate.  
     CONSTITUTION: To a hydrolyzate of an olefin/vinyl acetate copolymer having a C 5- olefin content of 5W95mol%, are added 0.003W1wt% of (B) sodium acetate and (A) acetic acid in an amount satisfying the equation, wherein [I] is the weight percentage of B contained in the copolymer hydrolyzate or its derivative, [II] is the MW of B, [III] is the weight percentage of A contained in the copolymer hydrolyzate or its derivative and [IV] is the MW of A. When the acetic acid content is lower than that given by the equation, the copolymer hydrolyzate, upon heating, discolors pale yellow to pink, and lowers in melt miscosity. This causes trubles in heat- molding. When the sodium acetate content is equal to or higher than 1wt%, the discoloration and decomposition of the copolymer hydrolyzate are accelerated, when the hydrolyzate is heated.

Title: Distance detecting device
Inventor: OGAWA YUKIO
IPC: G02B7/28
Filed: 1981-04-09
Abstract: PURPOSE:To decrease the load when a pickup lens is charged to a starting position, by converting the distance detecting signal through a converter so that the signal is decreased from the fixed value for a point at infinity stepwise with the decrease in the distance to an object. CONSTITUTION:The image signal from an image sensor 100 is outputted as distance data through a distance computing circuit 101. A distance data converter 102 converts the signal in such a way that the distance data is n when the object distance is located at the point of infinity, said data becomes n-1, n-2... as the object is brought to close, and said data becomes 0 at the closest distance. The output data is stored in a register 103. Meanwhile the pulses from a copper foil pattern detecting part 104 when the lens is moved are counted by a counter 15, and compared with the contents in the register 103 by a comparator 105. When both values agree, focus coincidence signal is outputted, Since the pickup lens can be moved from the nearest side to the focus position on the side of the point at infinity without the output of the counter 15, the charging load in a bar system can be decreased.

Filed: 1983-03-31
Abstract: PURPOSE:To reduce unbalanced distribution of magnetic flux of each path of iron core and reduce iron loss by making larger the cross section of internal iron core in the range of particular times than the cross section of external iron core. CONSTITUTION:A 3-phase 5-leg iron core is formed by laminating a yoke magnetic plate obtained by cutting a directional silicon steel belt at an angle of 45 deg. and the leg magnetic plate having two internal cores 11, 12 where the one leg is mutually adjacent and two external cores provided in contact with the external portion of said two internal cores. The core punching width forming internal core 11 is larger than the core punching width forming external core and cross section of internal core 11 is larger than that of external core 13. Distribution of magnetic flux of each magnetic path is uniformed by setting the cross section of internal core 11 to 1.08-1.25 times the cross section of external core 13. Thereby, magnetic flux density can be lowered and total iron loss can also be lowered.
