Title: Capillary position detection equipment of ultrasonic wave bonding equipment
Inventor: TORIGOE AKIZOU
IPC: H01L21/607
Filed: 1990-07-26
Abstract: PURPOSE:To easily enable precise detection, by coaxially fixing a circular disk for detection to one end of a retaining shaft of a bonding arm so as to be inclined, arranging a displacement sensor so as to eccentrically face the circular disc for detection, and detecting positions by using the sensor output. CONSTITUTION:A circular disk 11 for detection is coaxially fixed to one end of a retaining shaft 3, in the manner in which said disk is inclined by an angle thetato a line 12 perpendicular to the center axis of the retaining shaft 3, and the inclination direction is in parallel to a head 1 surface. A magnetic proximity sensor 13 is arranged excentrically from the center of the retaining axis 3, in the manner in which the central axis is positioned on the horizontal line passing the center of the circular disk 11 for detection, e.g. on a bonding surface 9. The magnetic proximity sensor 13 reads the displacement amount of the circular disk 11 for detection which amount changes in proportion to the rotation angle of the retaining shaft 3, i.e., the change of the rotation angle pi of a capillary 6. Thereby the rotation amount of the retaining shaft 3 can be detected, so that the position of the capillary 6 can be detected.

Abstract: PURPOSE:To always generate an exact calibration value voltage by providing a calibration value generating circuit for generating a calibration value voltage which has been corrected. CONSTITUTION:A calibration value generating circuit 6 generates a calibration value voltage being equal to a voltage corresponding to a prescribed strain amount outputted from a measuring bridge. Also, in a resistance value setting circuit 7, when a resistance value of a strain gauge is different from a reference resistance value, the resistance value of the strain gauge is set numerically, and a setting signal corresponding to the set resistance value is outputted. Subsequently, in a correction value generating circuit 8, a ratio of the resistance value which has been set by the setting signal of the resistance value setting circuit 7, and the reference resistance value is multiplied by the calibration value voltage of the circuit 6, and a corrected calibration value voltage is generated. Next, a gain setting circuit 3 receives selectively the corrected calibration value voltage and an output of the measuring bridge by an operation changeover switch 9, outputs the calibration value voltage by adjusting it to a prescribed level by a gain which is set by an eternal operation, and outputs it, and also, receives an output of the measuring bridge.

Title: Circuit and method for detecting completion of restoration of carrier wave and symbol timing and high-resolution television using it
Inventor: KAN TOUSHIYAKU
IPC: H04N5/44
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To attain a normal operation in a short time for an equalizer or the like by operating the equalizer or the like after the detection of end of carrier and symbol timing by utilizing a characteristic or the like that a DC offset is produced when the carrier is restored. SOLUTION: When the carrier is not restored, a DC offset is zero and when the carrier is restored and the frequency is locked, a DC offset is generated. Furthermore, the frequency is locked, then a timing error is reduced. When a symbol timing is restored, a change in the DC offset is small. When outputs of a 1st comparator 151 and a 2nd comparator 155 are all '1s', an output of an AND element 156 goes to '1' and a detection signal representing the end of carrier recovery and symbol timing recovery is outputted to an enable terminal of an equalizer. The equalizer is operated at first based on the output signal and remaining blocks are in operation through the operation of the equalizer.

Title: Clamping circuit
Inventor: TATEISHI MICHIKO
IPC: H03K5/007
Filed: 1990-07-27
Abstract: PURPOSE:To eliminate the need for a switch, a switch controlling signal and a terminal to be connected thereto and to receive the signal by charging up a charge to a capacitor till the capacitor reaches a prescribed voltage automatically when an analog input signal is decreased to a prescribed level or below so as to output a reference voltage to an input of an A/D converter. CONSTITUTION:When no analog input signal is inputted to a capacitor 24, a voltage lower than a voltage of a bias power supply 25 by a VBE of a transistor(TR) 21 is charged in the capacitor 24 and a same potential as a reference voltage V1 is applied to an input of an A/D converter. When a voltage higher than a voltage at no analog signal input is applied to the A/D converter from one terminal of the capacitor 24, a voltage change component in the analog input voltage with respect to the reference voltage is inputted to the A/D converter. When a voltage lower than a voltage at no analog signal input is applied to the A/D converter, since the same potential as the reference voltage V1 is applied to the input of the A/D converter, the input is clamped to the reference voltage V1. Thus, a switch, a switch controlling signal and a terminal to be connected thereto and to t receive the signal are not required.
