Title: Output amplitude stabilizing method for impedance measuring circuit
Inventor: OGAWA KAZUMI
IPC: G01R27/02
Filed: 1978-07-26
Abstract: PURPOSE: To enhance the measuring accuracy with the use of a simple construction by using measuring and standard detectors and resonant circuits, which have their electric and temperature characteristics made equal, so that they may coact to hold an equal temperature.  
     CONSTITUTION: When the transmission characteristics of a measuring detector  DET 1 are varied with the temperature variation, the transmission characteristics of  a standard detector DET 2 which is made to have the same transmission characteristics and which is made thermally coactive therewith are varied at the same rate. In case the equivalent series resistor of an inductor L1 of a measuring resonant circuit is varied with the temperature variation, the equivalent series resistor of an inductor L2 of a standard resonant circuit is varied at the same rate. As a result, the measuring output of the rate of the two detecting output voltages, i.e., the indicated value of a meter M is held constant. In case the output voltage of the oscillator 1 is varied, the varying ratio of the resonant voltages of the two resonant circuits becomes equal to offset the influences upon the indicated value of the meter M.

Title: Liquid crystal display element
Inventor: KAWAMATA MITSUHIRO
IPC: G09F9/35
Filed: 1985-04-29
Abstract: PURPOSE:To suppress a decrease in visibility even when pitch is made fine by generating a voltage higher than the threshold voltage of liquid crystal at a no-electrode part adjacent to a selected point so that the optical property at the no-electrode part is nearly the same as the optical property at the selected point. CONSTITUTION:A crosstalk voltage Vc has a value corresponding to a voltage applied to an adjacent selected point A, so the voltage applied to the selected point A is so set that the crosstalk voltage Vc developed at the adjacent no- electrode part C is higher than the threshold voltage Vt. Then, the optical property at the no-electrode part C adjacent to the selected point A is nearly the same as that at the selected point A and different from that at an unselected point B and when a zone display is made on negative basis, a quantity and a number are displayed in a beltlike shape continuously and brightly without any gap. When a segment display is made, a single segment having no break is displayed. Consequently, even when the pitch is made fine, a decrease in visibility is suppressed without decreasing the rate of the area of a segment electrode part to the unit area of a liquid crystal display element.

Abstract: PROBLEM TO BE SOLVED: To correctly display the C/N of a received digital broadcasting signal in a simple circuit by detecting the absolute value of an orthogonal demodulating circuit output signal, selecting a transmission bit frequency component in a filter circuit and executing detection. SOLUTION: The orthogonal demodulating circuit 7 of a satellite broadcasting receiver inputs an IF signal Si and outputs orthogonal demodulating signals from LPFs 3 and 4. A C/N detecting circuit 18 inputs one orthogonal demodulating signal, executes the both wave rectifying of the input signal and outputs the absolute value. BPF 16 frequency-selects the frequency component corresonding to a transmission bit number per one second in the output signal of an absolute value circuit 15 and a detection circuit 17 converts the transmission bit frequency signal Sc into a D.C. voltage Vd corresponding to its level. The signal level of the signal Sc is proportional to the C/N of the IF signal Si and the D.C. voltage Vd is also proportional to the C/N.  The signal amplitude of the signal Sc is comparatively large and the D.C. voltage Vd is sufficient for supply to a display means 13 so that an amplifier is not required especially. A clock signal for a voice processing circuit can be reproduced from the signal Sc.
