Title: Method for measuring non-steady flow field
Inventor: MURATA OSAMU
IPC: G01P13/00
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for measuring periodic flow field variation applicable for gas flow and external flow, too. SOLUTION: The physical quantity of flow is detected during a prescribed time by a sensor such as a hot wire type flowmeter, in each measuring point 110 provided within a measuring range 100 in a back wash of a body 150. Fast Fourier transformation is carried out for a detected signal of the sensor in each measuring point to find the amplitude of a marked frequency component based on a result transformed therein, and the amplitude as to each measuring point is distribution-displayed. The amplitude indicates the intensity of a varying component of the marked frequency in periodic variation of a flow field.  For example, when a frequency of a van Karman's vortex street is found pursuant to a defining expression for a Strouhal number, and an amplitude of a component in the von Karman's vortex street is found based on the fast Fourier transformation result to be distribution-displayed, movements of the von Karman's vortex street in the back wash of the body can be grasped.

Title: Operation monitoring system of switching apparatus
Inventor: KONISHI KATSUMI
IPC: G01M99/00
Filed: 1987-07-24
Abstract: PURPOSE:To make it possible to detect the abnormality of a delicate hydraulic system accurately and to save the labor of maintenance and security on the switching operation. CONSTITUTION:As a cause of the variation of the hydraulic pressure, there is the influence of the temperature other than an oil leak, and that is resulting from the variation of the pressure of the gas 6 enclosed in an accumulator 5 owing to the variation of the temperature. Consequently, even though the operational time of a pump unit 3 is measured, it cannot be decided accurately whether the measured time is owing to the practical oil leak or to the influence of the temperature. Theretore, on the operation of the pump unit 3 with no switching operation, only the number of of operations is measured, and the measurement of the operation time to detect the reduction of the injection amount of oil from the pump unit 3 is carried out only in the switching operation time. In such a way, even to the abnormarity of the delicate hydraulic system, an accurate detection can be made, and the labor saving to the maintenance and the security of the switching operation of a breaker can be realized.

CONSTITUTION:Light of a flame of a burner focused with a lens 2 is transmitted to a spectroscope 4 through an optical fiber 3 to extract lights with preselected wavelengths lambda1, lambda2...lambda4 from the spectroscope 4, amplified 5-1...5-4 to be converted into electrical signals proportional to degrees of spectral emission divergence Ilambda1, Ilambda2...Ilambda4 and the signals are amplified 6 and converted 7 into digital from analog to search the degree of spectral emission divergence at each wavelength. The results are inputted to a data computer 8. The tempera ture T of the flame is determined with a flame temperature computer 8 at degrees of spectral emission divergence Ilambda1 and Ilambda2 for two close wavelengths, for example, lambda1 and lambda2 among those searched and a distortion in the tempera ture distribution of the flame is obtained from the temperature T. Thus, combus tion state of burners is diagnosed by judging imbalance of air-fuel ratio of the burners, variation in the generation of soot particles and the like.
