Title: Method for measuring particulate number in calibrating liquid
Inventor: FUKAI YOSHIKAZU
IPC: G01N15/00
Filed: 1990-07-27
Abstract: PURPOSE:To make it possible to perform accurate measurement by dropping calibrating liquid on a grounded substrate, evaporating the liquid, reducing and and drying the liquid droplet, and counting particulates remaining on the substrate. CONSTITUTION:Liquid which is dispersion medium is evaporated from a liquid droplet d of calibrating liquid which is formed on a substrate 2 on a grounding plate 1. Then, the diameter of the liquid droplet D is reduced. Since the mobil ity of particulates is in the sufficiently high state, the particulates move so that the particulates are always present in the liquid droplet. When the diameter of the liquid droplet is reduced, the particulates are concentrated. The particulates finally remain in the small region. Therefore, the accurate measure ment can be performed by counting the number of the particles with this region as the judging region.

Title: Inverter equipment
Inventor: HIROSE HIROYUKI
IPC: H05B41/24
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To provide a simple and low-cost single-transistor high power factor inverter equipment. SOLUTION: An auxiliary winding 34 is installed which is to be wound around an iron core 32 of an inductor 30 for vibration. The auxiliary winding 34 is inserted in series with a rectifying power supply 10. The voltage polarity of the auxiliary winding 34 is so set that the half-wave voltage formed during an ON period of a switching element 40 may have the same polarity as the rectifying power supply 10. By specifying the polarity of the auxiliary winding 34, the backward voltage of the inductor 30 for vibration can be used. Since the backward voltage is higher than the forward voltage, the number of turns of the auxiliary winding 34 is reduced when the backward voltage is used. The forward voltage can also be used, however, in such a case, the auxiliary winding 34 works on the subtractive polarity and excessive current is allowed to flow.  Furthermore, the use of the forward voltage is not practical since a thick iron core 32 is necessary.
