IPC: B67D1/07
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To prevent the discharge of purified water due to a misoperation without deteriorating the operability by checking the turn-on operation of a water discharge switch in two steps.  
     SOLUTION: Whether the water discharge switch 107 of a keying means 104 is turned on or not is judged by a control means 114, and, when the switch 107 is turned on, a control signal to indicate the fact is outputted to an indicating means 128. Consequently, a water discharge lamp is flickered for a specified time by the indicating means 128. Subsequently, if the switch 107 is again turned on in a specified time is judged by the control means 114, when the switch 107 is turned on, a user is judged to be willing to discharge purified water, and a control signal to indicate water discharge is outputted to the indicating means 128. As a result, the water discharge lamp is lit by the indicating means 125. A control signal to discharge the purified water in a tank is outputted by the control means 114 to a water discharge valve driving means 126.

Title: Wafer rotating direction detecting method
Inventor: ATSUTA HITOSHI
IPC: G06T1/00
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To detect the direction of rotation of a wafer without using the rotary structure of a wafer stage by a method wherein, based on the direction of a matching pattern detected for an image, one equivalent revolution angle is selected from a plurality of equivalent revolution angles, and the revolution direction of the wafer to be measured in determined from the selected equivalent revolution angle. SOLUTION: The read-out image is clockwisely rotated in the amount of preliminary rotation angle of α 2 pr by affine transformation, and an image is formed. The pattern, which is matched to a model pattern MPa, is detected by a pattern matching treatment using the above-mentioned rotated image. At this time, the four model pattern, which are rotated at 90 degrees, are formed in advance as template images. Among the above-mentioned four template images, the template image having the highest degree of matching is selected and the rotating direction of the wafer to be measured is determined from the selected template image. As a result, the rotating direction of the wafer can be detected without using the rotary structure of the wafer stage.

Title: Photoelectric separation type sensor
Inventor: WADA TAKETSUGU
IPC: G08B17/103
Filed: 1992-07-28
Abstract: PURPOSE:To reduce the cost and improve the quality by making the wiring length long with simple circuit constitution. CONSTITUTION:A capacitor Cs is connected between the base and emitter of the transistor(TR) Q2 of a light reception part 1. A light emission part is powered ON and when the TR Q2 is ON, the capacitor Cs is charged with the base-emitter voltage VBE 0.6V of the TR Q2. When a TR Q1 is turned ON with a timing signal for light emission, charges in a floating capacitance Cx are discharged through the capacitor Cs. Therefore, the electric power to the light emission part clearly rises, and consequently there is no problem even if the wiring length is long.
