Inventor: KONO KENJI
IPC: G01M11/00
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To reduce storage capacity needed for calculation by matrixing differential terms except one specific variable among more than a specific number of variables, diagonalizing the matrixed differential terms, solving a differential equation as to variables derived from the diagonalized differential terms, and analyzing a physical phenomenon. SOLUTION: A CPU 100 analyzes the physical phenomenon by executing an arithmetic expression entered an analytic program for the operation of a determinant through an operating system stored in a system memory 101 or on HDD 105. Namely, the differential terms are matrixed by a finite element method except one of >=3 variables. The matrixed differential terms are diagonalized and the differential equation as to one variable which is derived from the diagonalized differential terms is solved to analyze the physical phenomenon. Consequently, the dimensions of an array can greatly be reduced, the storage capacity needed for calculation is made small, and the calculation time is made short.

Title: Pressure switch
Inventor: HONMO YUKIO
IPC: G02B26/08
Filed: 1992-12-28
Abstract: PURPOSE:To provide the pressure switch which has its zero point easily adjusted and is high in safety and reliability. CONSTITUTION:A light-reflective pressure receiving film 1 completely partitions two chambers A and B from each other deflects sensitively corresponding to the difference pressure between the chambers A and B. A two-branch fiber 4 includes a fiber 4a which transmits light from a light emission part 2 to the pressure receiving film 1 and a fiber 4b which sends light reflected by the pressure receiving film 1 to a light reception part 3. The tip of this fiber bundle 4c faces the pressure receiving film 1. Denoting the pressure in the chamber A as P1 and the pressure in the chamber B as P2, the pressure receiving film 1 closes the light exit of the fiber 4a by coming into contact with the fiber bundle 4c when P1>P2, so no light is guided in the light reception part 3, so that the switch turns off. When P1<P2, on the other hand, the pressure receiving film 1 leaves the fiber bundle 4c, so the reflected light is guided in the light reception part 3, so that the switch turns on.
