Title: Method for apparatus for detecting foreign matter and dust
Inventor: FUKUSHIMA YOSHIMASA
IPC: G01N21/88
Filed: 1989-02-17
Abstract: PURPOSE:To enable detection of foreign matters and dust and thereby always maintaining a good and constant detection sensitivity by correcting a detection value of scattered light generated with the presence of a foreign matter and dust with due consideration to the effect of an intensity of reflected light on a substrate. CONSTITUTION:When a substrate 1 is irradiated with a laser light 4, the laser light 4 is separated into reflected light 8 and transmission light 9 with a dust preventing film 2 pasted on the substrate 1. Then, the laser light 4 transmitted through the dust prevention film 2 reaches the top of the substrate 1 and scattered light 5 is caused with the presence of a foreign matter and dust on the substrate 1. Then, intensity of the scattered light 5 is detected while intensity of the reflected light 8 on the dust prevention film 2 is detected. Then, the intensity of the laser light reaching the top of the substrate 1 transmitted through the dust prevention film 2 is calculated from a difference between the intensity of the laser light before the entry of the dust prevention film 2 and the intensity of reflected laser light. Moreover, by correcting a detection value of the scattered light allowed for a variation of the transmission laser light based on a calculated value of the transmission light, a constant detection sensitivity can be always obtained without being affected by the fluctuation of a irradiation laser light due to the presence of the dust prevention film and a difference in a thickness of the dust prevention film.

Abstract: PURPOSE:To achieve a higher reliability, by ORing of a plurality of signals based on a plurality of signals for controlling the ignition of an SCR to draw an induced voltage of a motor as rotation information thereof when the ORed output of is zero. CONSTITUTION:Outputs of four comparators are supplied between terminals C and D through an OR gate.

A voltage across the motor is applied between terminals A and B, rectified with a full-wave rectifying circuit DS1 and the rectified voltage adds to both terminals of a series circuit of both resistors R1 and R2. When the voltage at the common connection point (a) between both terminals exceeds the voltage of a Zener diode ZD, the SCR9 is turned ON when the coupler PC1 is OFF (period TS). In this case, as a full-wave rectified voltage develops between terminals E and F, the voltage is used as detection signal of excessive speed.
