Title: Angle-of-rotation detector using resolver
Inventor: IMAZU TOMOYA
IPC: G01B7/00
Filed: 1995-06-30
Abstract: PURPOSE: To reduce memory capacity of a searching table without lowering detection accuracy in an apparatus for detecting an angle of rotation using a resolver. CONSTITUTION: An arithmetic circuit 32 computes y[i]=y[i-1]-y[i-1].cosθDET +(1-y[i-1]).sinθDET using sinθDET using sinθDET, and cosθDET (θDET: an angle of rotation to be detected of an object 1 to be measured) repeatedly to obtain a convergent value y[N]. f(θ)=sinθ/(sinθ+cosθ) is stored in a searching table 31 , and an arithmetic circuit 33 searches θ=f<-1> (y[N]) corresponding to a convergent value y[N] from the searching table to obtain an angle signal θ'DET. Any one of 0, π/2, π, 3π/2 is added to the angle signal θ'DET according to a quadrant discrimination signal Sn of a quadrant discrimination circuit 33 and the results are outputted as an angle of rotation θDET.  This eliminates the need for a searching table for computing convergence and can only use one searching table for correction having f(θ) stored thereby enabling a reduction in the memory capacity and moreover, preventing a drop in the detection accuracy.

Title: Optical connector
Inventor: TANAKA MICHIO
IPC: G02B6/36
Filed: 1983-09-12
Abstract: PURPOSE:To obtain easily an optical connector having an intricate shape by pressurizing a resin material so that said material is infiltrated into the fine holes of a ferrule for the optical connector consisting of a ceramic material. CONSTITUTION:A ferrule 31 and a sleeve 41 are formed of a ceramic material and are disposed with numerous fine holes on the surface thereof. A resin material is pressurized so as to be forced and infiltrated into the fine holes to form the dense surface 5 of the ceramics. The fine holes 51 are therefore filled with the resin material. Coloring of the ceramics is thus made possible by forming a surface hvaing the holes 51 over the entire surface of the ceramics or a part thereof and infiltrating under pressurization powder having a color such as a pigment into the parts of the holes 51. The position and direction where the ferrule 31 and the sleeve 41 are fitted are thus determined and the optical connector having an intricate shape is easily manufactured.

Accordingly, only replacing A surface with the C surface is enough in the cathode grounding made, similar to the anode grounding mode. Through these procedures, the anode grounding mode and the cathode grounding mode can be changed with each other.

Filed: 1991-07-08
Abstract: PURPOSE:To obtain wiring which is short in process time and small in bending. CONSTITUTION:When a two-divisonal process is repeated hierarchically in an area to be wired, the cut position 1d of a net extending to two areas Di+1, 1, Di+1, and 2 at each of respective hierarchical levels and then the nets in the partial areas Di+1, 1, Di+1, and 2 are classified into nets to be processed hierarchically and nets to be processed flatly. The nets 2 which are made flat are wired by flat algorithm and the hierarchical nets are passed to a hierarchical process of next level, so that the wiring process is repeated hierarchically until the partial areas reaches the minimum size. Consequently, a wiring result which gives small bending is obtained and a self-evident wiring path is processed flatly, so the wiring result is obtained at a high speed.

Abstract: PROBLEM TO BE SOLVED: To suppress the dispersion of the film thickness of a diaphragm by forming the second embedded layer using the material having the large etching selection ratio for the diaphragm at a position connected to the first embedded layer. SOLUTION: A first embedded layer 6a, wherein high-concentration impurities are injected, is formed at a position where a first diaphragm 2a is constituted at the upper part of a silicon substrate 5. A second embedded layer 6b comprising a silicon oxide film is formed at a position where a second diaphragm 2b is formed at the upper part. This silicon oxide film is etched by etching solution based on hydrogen fluoride. Therefore, the etching of the part other than the second embedded layer 6b seldom occurs, and there is no dispersion of the film thickness of the second diaphragm 2b. Furthermore, since a piezoelectric resistor R is formed on the first diaphragm 2a comprising a single crystal, the piezoelectric coefficient is high in comparison with the case of the formation on a polycrystal, and the reduction of sensitivity can be prevented.
