Title: Detecting equipment for height of position of substrate
Inventor: IMAI YUJI
IPC: H01L21/68
Filed: 1993-11-08
Abstract: PURPOSE:To highly precisely detect the height position at a measuring point on a substrate, by forming a second irradiation point on a line different from an arrangement line of first irradiation points on a substrate, receiving the reflected light from the substrate when the substrate is displaced from the height position detection range of a light receiving means, and detecting at least the displacement direction. CONSTITUTION:Light casting means 60-65, 66a irradiate a substrate W with a second luminous flux, so as to form a second irradiation point on at least a line which is different from an arrangement line of first irradiation points on the substrate W and parallel with the arrangement line. A second light receiving means has a detection range approximate to the detection range of height position of the substrate W which can be detected by a specific photodetector out of the first a photodetectors and receives the reflected light of the second luminous flux from the substrate W. When the height position of the substrate W is displaced from the detection range of the height position of the substrate W of the second photo receiving means, a direction sensor detects at least the displacement direction by receiving the reflected light from the second luminous flux from the substrate W. Thereby the height position can be detected with high precision.

Title: Cross modulation compensating device
Inventor: TAKIZAWA TOSHIYUKI
IPC: H04B7/15
Filed: 1985-12-11
Abstract: PURPOSE:To prevent a change in the distortion of an output signal even when a signal level is changed by controlling the distortion compensation of a distortion compensation means in response to an AGC voltage in using the signal of a distortion component formed from an input signal so as to compensate the distortion in the input signal. CONSTITUTION:An AGC voltage generating means 101 in a radio equipment detects the level of a pilot signal in the input signal to generate the AGC voltage. The radio equipment controls the gain of an amplifier in response to the AGC voltage so as to stabilize an output signal level. A distortion compensation means 102 generates the signal of distortion component from the input signal and the distortion signal compensates the distortion in the input signal. In applying the distortion compensation, a control means 103 controls the distortion compensation in the means 102 to be changed in response to the AGC signal generated in the means 101. Thus, even if the signal level is fluctuated by fading and the cross modulation distortion in the signal is fluctuated, the change in the distortion in the output is prevented.

Title: Sawtooth wave signal generation circuit
Inventor: FUJISAKI HITOSHI
IPC: G01R31/3183
Filed: 1994-11-14
Abstract: PURPOSE: To fix the output amplitude of sawtooth wave signals by defining comparator output as the control signals of an analog switch, defining the sawtooth wave signals as one input of the analog switch and grounding the other input. CONSTITUTION: Since a constant current source Q1 charges a capacitor C1 by a constant current in a period when a switching transistor Q2 is off, the sawtooth wave signals are generated in the collector of the constant current source Q1. The signals are inputted to one input of a comaprator IC 3 and an analog switch IC 4. When the level of the sawtooth wave signals is higher than a reference voltage, the output of the IC 3 becomes a low level and the IC 4 is connected to a GND side. Thus, the level more than the reference voltage is not outputted in the output of the IC 4. In the meantime, switching pulses are supplied from an inverter IC 1 through a resistor R9 to the output of the IC 3, the IC 4 is connected to the GND side in the period when the transistor Q2 is on and a function for eliminating the difference of the low level of output signal waveforms is performed.
