Title: Reader for character on wafer
Inventor: ISHII HIROYUKI
IPC: H01L21/66
Filed: 1990-11-09
Abstract: PURPOSE:To increase the reliability of read by a method wherein a strip-like laser beam is emitted on characters drawn on a wafer and the wafer at a prescribed incident angle and a reader is provided with a camera for catching direct reflected light, which is reflected regularly from the wafer, and a camera for catching one part of the laser beam, which is reflected irregularly from the end face of the roughness of the characters. CONSTITUTION:A laser beam is generated by a laser beam source 1 and the laser beam is deflected by rotating a mirror 3 in one direction. The deflected laser beam is shaped into a strip-like laser beam by a shaping lens 4 and the shaped laser beam is emitted on a wafer 6. At this time, the wafer 6 is moved in the direction vertical to the deflected direction of the laser beam. A moved position signal of the wafer 6 is sent to a character image processing part. Direct reflected light, which is reflected from the wafer 6 by the laser beam, is catched by a camera 2. On the other hand, one part of light, which is reflected irregulary by the side end of characters 7, is catched by a camera 5. Then, an imaging signal of the camera 2 is made to match on the basis of a position movement signal of the wafer and a two-dimensional image is obtained. Thereby, the boundaries between the characters an be distinctly recognized.

Title: Thermal current meter
Inventor: NUKUI KAZUMITSU
IPC: G01F1/68
Filed: 1994-11-14
Abstract: PURPOSE: To obtain a thermal current meter in which measurement can be carried out continuously with low power consumption. CONSTITUTION: Sensor resistors 41, 42 are disposed, respectively, on the upstream and downstream side of a gas flow and a heater resistor 43 is disposed in the center. A constant current circuit 61 supplies a constant current intermittently to the heater resistor 43 through a switch 62 being switched by means of a switching signal 63. In this regard, minimum necessary heating value is ensured for the heater resistor 43 such that the output from a differential amplifier 53 has at least the minimum level required for detection of current velocity. Duty ratio of the switching signal 63 is set at a value sufficient for ensuring the minimum necessary radiation of heat. The period of intermediate supply is set lower than two times of the thermal time constant of the heater resistor 43.  When the flow rate is zero, the sensor resistors 41, 42 have an equal resistance and a bridge circuit 50 is balanced to produce zero output from the differential amplifier 53. When the flow rate increases, the temperature of the sensor resistor 42 increases while the temperature of the sensor resistor 41 decreases to cause a difference between both resistances thus increasing the output from the differential amplifier 53.

Title: Motor speed controller
Inventor: MATSUMOTO TATSUOKI
IPC: H02P29/20
Filed: 1991-11-21
Abstract: PURPOSE:To realize smooth speed control of a motor in quite low speed region by employing a low resolution pulse encoder. CONSTITUTION:A predictive speed operating section 24 is fed with pulses having control period Ts counted through a counter 25. The operating section 24 operates a predictive speed based on thus fed pulses until a speed detection pulse (period Tp) is fed from a pulse encoder 15. Thus operated predictive speed is then compared through a comparator 23 with an estimated speed value outputted from a second difference section. If the estimated speed value is higher than the predictive speed, contact 2 of a relay is turned ON while it is turned OFF if the estimated speed value is lower than or equal to the predictive speed. Consequently, a motor is started at the predictive speed until a speed detection pulse arrives.
