Title: Method and equipment for measuring flatness of thin plate
Inventor: IBATA HARUHIRO
IPC: G01B21/20
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To measure a thin steel plate mounted on a surface plate accurately, which can be realized by a conventional method because deformation due to self-weight is included, an extra suspension test is required for measuring a warp and significant labor is required for measuring work, by detecting the spatial coordinate at a moment of time when the thin plate is positioned in the air an determining the flatness. SOLUTION: A thin plate 1 is floated by jetting the air from the surface of a measuring head 2 and the spatial coordinate of the thin plate 1 is detected by means of laser type distance sensors 10,... located above when jetting of the air is stopped and the thin plate 1 stays in the air while falling freely after being elevated continuously by inertia thus calculating the flatness. Warp or waving insusceptible to self-weight appears straight on the thin plate 1 in the air where external force does not act other than gravity. When the shape of the thin plate is detected under that state, warp and steepness can be determined in a short time and the flatness can be measured efficiently.

Title: Automatic power factor controller
Inventor: ISHIKAWA FUKUO
IPC: G05F1/70
Filed: 1988-09-12
Abstract: PURPOSE:To suppress a rush current or higher harmonic resonance, which is generated when a capacitor for phase advance is connected to a power line, without using an equipment such as a reactor by using a variable resisting means and a ceramic capacitor. CONSTITUTION:For an element to control the connection and opening of a capacitor 30 for phase advance by the ceramic capacitor to the terminal of a load 2 such as an inductive motor to be connected to an AC power source 1, the simple form only of a variable resisting means 40 is obtained. Then, a transient phenomenon to be generated in a power line 12 is controlled as much as possible by utilizing the time resistance change of the variable resisting means 40. Namely, since the capacitor 30 for phase advance is connected to the alternative current power line 12 by the smooth lowering of internal resistance in the variable resisting means 40, the rush current to transiently rush into the capacitor 30 for phase advance is eliminated even without using the reactor and the higher harmonic resonance is not generated. Since the ceramic capacitor is used as the capacitor 30 for phase advance, electrostatic capacity can be set more finely in comparison with an oil capacitor and even at time of a light load, a power factor can be improved.
