IPC: G06T7/00
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To automate inspection by recording an image of a region containing a border between adjacent fields, determining a singular figure among figures which matches a pattern image through pattern matching, and quantifying a shift from a plot position based on a differential vector between a measurement value and a set value, which exist in one and other field regions.

Filed: 1988-12-27
Abstract: PURPOSE:To eliminate a contaminant or an unneeded object positively by supplying a cleaning liquid to a wafer after exposing the semiconductor wafer to a stream environment which is soluble to the semiconductor wafer cleaning liquid. CONSTITUTION:A wafer 12 is attached to a vacuum chuck 13 of a treatment tank 11 and the treatment tank 11 is sealed by a covering body 11b. Then, a steam generator 15 is used to generate a stream 23 which is easily soluble in a cleaning liquid or an etching liquid.

Title: Lead-acid battery device
Inventor: NAMIKI AKIRA
IPC: H01M2/38
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To promote the reaction between an electrolyte and an electrode active material and improve the performance of a lead-acid battery by providing a lead-acid battery device formed of the lead-acid battery and a vibrating mechanism for vibrating the lead-acid battery. SOLUTION: A vibrator driving signal is transmitted from a vibrator control part 22 to vibrated a vibrator 14. The vibration of the vibrator 13 is transmitted to the whole body of a lead-acid battery 12 through water 6. The vibration actually transmitted to the electrolyte of the lead-acid battery 12 is monitored by an acceleration sensor 13. In discharging, for example, Pb which is an active material for negative electrode plate is changed to PbSO4 . When the whole lead-acid battery 12 is vibrated at this time, a negative electrode plate 102 within the lead-acid battery 12 is vibrated, whereby lead sulfate is prevented from being greatly developed, and made into fine particles. In changing, the led surface formed on the negative electrode plate is returned to the original Pb.  Since the lead sulfate satisfactory contacts the electrolyte because it is sufficiently fine, the charging can be finished in a short time with a high reaction speed.
