Title: Preparation of semiconductor acceleration sensor
Inventor: TSUGAI MASAHIRO
IPC: G01P15/12
Filed: 1988-05-30
Abstract: PURPOSE:To accurately adjust the thickness of a thin wall part, by forming an etching stopper layer composed of an insulating layer on the surface of a semiconductor substrate and forming a groove part, which forms the thin wall part of a support beam, to the rear thereof by etching. CONSTITUTION:After an etching stopper layer 32 composed of an insulating layer is formed on an Si-substrate, a part of said layer 32 is removed to form a polycrystal Si-layer 32a. Subsequently, the layer 32a is converted to a monocrystal Si-layer and, thereafter, the first insulating layer 35, a piezoelectric resistor 36, connection wirings 37 and electrodes 38 are formed by diffusion and, further, the second insulating layer 39 is formed to the rear of the substrate 31. Continuously, the insulating layer 39 is selectively etched so as to leave the central part and four peripheral edge parts thereof and anisotropic etching is applied using the remaining insulating layer 39 as a mask to form a separation groove part 40. By this method, the thickness of the groove part 40 can be adjusted precisely and heat stress variation due to bimetal effect can be reduced.

Title: Device and method for detecting overlapped feeding
Inventor: OHARA SHUNICHI
IPC: B65H5/02
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To surely detect overlapped letter feeding of any combinations by providing a detecting means for detecting the state of a letter surface in a location first contacted with the tip of a letter and extracting, determining the characteristic of overlapped feeding by an overlapped feeding determining means. SOLUTION: Carrier routes in the outer and inner sides of a turning means form a letter opening section 9 which does not hold a letter. A detecting means is a distance sensor 2 for measuring the height or fluctuation of a letter surface. When the tip of an upper one of overlappingly fed letters is contacted with a butting section 11, the letter is carried along the inner carrier route 5c and contacted with the outer carrier route 5b in the butting section 11. The letter is held between a carrier belt 5a and a carrier belt 4c in the position of a guide roller 6a to receive a carrying force, and it is carried being bent like a letter 12 by the carrying force of a carrier belt 4b. For the overlapped letters, after the lower letter 12 is contacted with the butting section 11 to be bent, the overlapped letter 10 is moved straight ahead to the butting section 11.  In the vicinity of the butting section 11, the overlapped letters are separated between upper and lower parts.
