Title: Transfer device of electrophotographic copier
Inventor: TERADA RIYOUHEI
IPC: G03G15/16
Filed: 1979-04-11
Abstract: PURPOSE: To prevent the drop-out of images and maintain the stable images by providing a transfer roller in the forward position of the copying process of a transfer charger, forming a large-diameter part to this transfer roller and energizing the same in the photoreceptor direction.  
     CONSTITUTION: When a photoreceptor 1 revolves, a transfer roller 9 is driven to revolve by a large-diameter part 13 which is in contact with the photoreceptor 1. Since the roller 9 is held energized in the direction of the photoreceptor 1 by a pressure spring 12, the spacing between the guide shaft part 8 of the transfer roller 9 and the outside circumferential surface 2 of the photoreceptor 1 is constant. The spacing size may be determined as desired by setting of the diameter of the guide shaft part 8 and the diameter of the large-diameter part 13, and this improves the adhesion of the transfer paper 14 to the photoreceptor 1 and obviates the occurrence of the drop-out at the trasfer. In addition, the adhering may be made to the stable state early and therefore the stable images are obtainable.

Abstract: PURPOSE:To highly precisely operate an intersecting point of three faces by setting up a plane on an intersecting face between two faces and finding out an intersecting point among three faces on the plane. CONSTITUTION:An intersecting point between the 1st intersecting line made by faces SO, S1 and the 2nd intersecting line mode by faces SO, S2 is found. A plane P is set up on a prescribed point on the 1st intersecting line, an intersecting point between the plane P and the 2nd intersecting line is found, a distance D between the intersecting point and the 1st intersecting line is found, and an intersecting point is found from the changing state of the distance D. Consequently the differentiation of the distance D by line length on the 1st intersecting line depends upon only a change in the line length. Thereby the value of distance D=0 can be calculated by changing the line length and tracking the change of the distance D, so that an precise intersecting point can be found out. In addition to a normal program for computing the intersecting point calculation of three faces, an intersecting point calculating program based upon a distance function is also stored in a program memory and the intersecting point operation of three faces is executed by using either one of the programs in accordance with a situation.

Title: Manufacture for semiconductor acceleration sensor
Inventor: ISHIO SEIICHIRO
IPC: H01L29/84
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To sufficiently detect an acceleration by suppressing noticeable sensitivity decrease without increasing a chip size which results from a shift of a relative formation position of a beam part and a gauge resistor. SOLUTION: Base parts between a beam part 12 and a frame part A or a weight part B become stress maximum parts F1, F2. A gauge resistor 6 is formed at a position shifted by a predetermined amount from the stress maximum part F1, F2. That is, in forming the gauge resistor 6, a formation position of the gauge resistor 6 is shifted because of various factors such as a mask shift, etc. If the gauge resistor 6 is formed at the stress maximum part F1, F2 outside the beam part 12, a sensitivity is decreased considerably. Therefore, the gauge resistor 6 is formed so as to be inside the stress maximum part F1, F2 even at the occurrence of a maximum shift.
