Title: Transmitting and receiving method of television conference device
Inventor: MATSUOKA SHINICHI
IPC: H04N7/08
Filed: 1983-02-04
Abstract: PURPOSE:To obtain a signal to be applied to a TV receiver by switching a video signal from two cameras alternately at every field and continuing the signal to form a composite video signal and to process the respective continuous composite signals by two storage circuits and composite circuits on a receiving side. CONSTITUTION:Two video cameras 1, 2 on a transmitting side are driven by a clock signal from a synchronism signal generating circuit 3, the video signals L, M having the same phase are composed by a video composite circuit 4 and the composite video signal N is sent from a terminal 5 to a transmission line. The signal N is distributed by a video distributing circuit 102 on the receiving side and the composite video signal P is applied to a video separating circuit 103 and a synchronism separating circuit 104 respectively. The circuit 103 applies the videos Q, T deframed at every field of the signals L, M to the storage circuits 105, 106 and also applies the videos to video composite circuits 108, 109. Under the control by a control circuit 107, the video signals R, U delayed by one field are applied from the circutis 105, 106 to the circuits 108, 109 and the outputs of the circuits 108, 109 are applied to the TV receivers 110, 111.

Title: Power amplifier
Inventor: YOKOYAMA KENJI
IPC: H03F1/02
Filed: 1986-01-29
Abstract: PURPOSE:To apply a necessary minimum operating supply voltage corresponding to the amplitude value of a signal to be amplified across an analog power amplifier so as to improve the efficiency of the amplifier, by increasing and decreasing little by little the output voltage of a digital power amplifier in a voltage step corresponding to the smallest bit in accordance with the amplifying value of an input signal voltage. CONSTITUTION:The output of an AD converter circuit 7 increases and decreases correspondingly to the positive side peak value of an input signal Vi and the output voltage of a variable voltage source 1a is switched in stages. Namely, when the positive side peak value is high, the collector voltage +Vc of a transistor (TR) Q1 becomes higher and, when the peak value is low, the collector voltage +Vc becomes lower. Similarly, outputs of the AD converter circuit 7 and another variable voltage source 1b increases and decreases correspondingly to the negative side peak value of the input signal Vi and, when the peak value is high, the collector voltage -Vc of another TR Q2 becomes lower. When the peak value is low, the collector voltage -Vc of the TR Q2 becomes higher. Since the number of switching stages is 16 stages (4 bits) to the positive side and another 16 stages to the negative side in this case, switching of the supply voltage is performed little by little with a less number of power sources.

Title: Flaw measuring method for minute pattern
Inventor: FUJITA HIROO
IPC: G01B11/24
Filed: 1994-02-14
Abstract: PURPOSE:To provide a measuring method in which the shape flaw such as the disconnection, the short circuit or the like of a minute pattern such as a transparent electrode is detected with high accuracy by an optical means. CONSTITUTION:A laser beam which has two intensity peaks is scanned two- dimensionally on the face of a pattern, the intensity of reflected light is detected by a two-split-light-receiving device 15 in a scanning-fixed-point position, and a differential signal and a composed signal are created. When a peak is generated in the differential signal, the width of the peak, the intensity of the peak and the generation position of the peak are detected. In addition, the intensity value of the composed signal is detected. The kind and the size of a flaw in the pattern are found by means of a slice level which is set on the basis of the detected values and on the basis of the maximum intensity and the minimum intensity of the composed signal. When two-beam light is used, a two-dimensional scanning operation can be performed at high speed, and its sensitivity can be made high. Since the flaw can be detected in real time by a simple signal processing operation, the flaw measuring method is suitable for an in-line measurement in a production line.
