Title: Detection of revolution drop for cooling fan
Inventor: HIRANO MINORU
IPC: F04D27/00
Filed: 1990-11-29
Abstract: PURPOSE:To enable accurate detection of a revolution drop of a plurality of cooling fans by determining a difference in number of revolutions between the cooling fans to check whether the difference is above a reference value for the difference or not. CONSTITUTION:Numbers of revolutions R1 and R2 of cooling fans 2 and 3 are compared with individual reference values N. As a result, when the number of revolutions R1 and R2 are both below the reference values N, a power source of an electronic equipment 1 is turned OFF. When any one of the revolutions alone is below the reference value N, a warning is given of a drop in the number of revolutions of the fan involved and the fan is repaired and exchanged. Here, when the numbers of revolutions R1 and R2 are both above the references N, a difference of ¦R1 - R2¦ obtained from the detection 5 of the difference is compared 6 with a difference reference value M. When the results are above the reference value M, a warning is given indicating that the fan broken down is being rotated idly by a normal fan and the fan broken down be repaired and exchanged. This enables the detecting of a drop in the number of revolution as well accurately as caused by an idle rotation of the fan driven by an air flow of the normal fan when supplied with no driving power because of a disconnection or the like of a driving circuit.

Title: Method and device for measuring radius of curvature
Inventor: SAKAKI TAIZO
IPC: G01B21/20
Filed: 1990-11-29
Abstract: PURPOSE:To easily measure the radius of curvature of an object to be measured by finding the radius of curvature of the wave front of a reflected luminous flux at the position of an image pickup element by performing arithmetic operations based on spatial frequency. CONSTITUTION:A parallel luminous flux from a laser light source 1 radiates an object 0 to be measured after passing through a shearing means 2 and the reflected light of the luminous flux from the curved surface of the object 0 is made incident to the means 2. Then the light is divided into two luminous fluxes after the light is reflected on the closely facing two surfaces of parallel plates 21 and 22 and, at the same time, sheared. The sheared luminous fluxes are made incident to a line sensor 3 and form interference fringes. The output of the sensor 3 is fetched by an arithmetic means 4 and the spatial frequency (f) of the interference fringes is calculated by performing arithmetic operations for analyzing frequencies. The arithmetic operation of a formula, Z[{S/(flambda)}-L], is executed by using the calculated spatial frequency (f) and the constants lambda, S, and L of a measuring instrument. Therefore, the radius of curvature of the object 0 can be found from the formula. In other words, when the spatial frequency (f) of the interference fringes is known, the radius of curvature (r) of the wave front can be found and the radius of curvature of the curved surface of the object 0 can be calculated from the formula by using the found radius R and the length of an optical path L.
