Title: Tuning apparatus
Inventor: CHIBA MITSUHARU
IPC: G10G7/02
Filed: 1988-12-26
Abstract: PURPOSE:To concentrate turning only to an untuned index by comparing stored contents in the present and past and preventing an octave and a pitch name from being displayed when the same compared result is continued for more than a set number. CONSTITUTION:The output of an octave and pitch name retrieving part 4 and the octave and pitch name in the present and past are compared. Then, when the same compared result is continued for more than the set number, the octave and pitch name are controlled not to be displayed in a display part 7. Thus, the display of the octave and pitch name can be easily observed by preventing the display after a tuning decision, for which the tuning is completed, is displayed for the prescribed number out of the display of the plural compared results or tuning decision. Then, the speedy tuning can be executed by concentrating the tuning to the tuning discrimination, for which the tuning is not completed yet.

Title: Converter circuit for inverter device
Inventor: KIMURA SHINSUKE
IPC: G05F1/613
Filed: 1987-12-24
Abstract: PURPOSE:To reduce power consumption and to reduce the pressure resistance of a capacitor by controlling current flowing into one of balance resistors so that voltages respectively applied to both the terminals of two capacitors connected in series are equal. CONSTITUTION:Voltages respectively applied to both the terminals of the capacitors 3, 4 are defined as V3, V4. In case of V4>V3, the non-inversional input of an operational amplifier 10 goes higher potential, the output of the amplifier 10 is turned to 'H' and the base potential of a transistor (TR) 9 is raised by a time constant determined by a resistor 15 and a capacitor 16. Thereby, current IC flowing into the TR 9 is increased, the V4 is reduced, the V3 is increased, and V4>V3 is formed. Thereby, the inversional input of the amplifier 10 goes higher potential, its output is turned to 'L' and the base potential of the TR 9 is reduced by the time constant determined by the resistor 15 and the capacitor 16. Since the current flowing into the TR 9 is reduced, the V4 is increased and goes larger than the V3. Since said operation is rapidly repeated, the V4 and V3 are almost equally held.

Filed: 1993-12-24
Abstract: PURPOSE:To improve display unevenness and contrast and to use nonlinear elements with a low threshold voltage and good controllability by improving a charge holding characteristic during a holding period in a matrix display device which employs nonlinear elements. CONSTITUTION:Scanning signal potential during a holding period based on a reference potential differs between after the selection period of a positive polarity and after the selection period of a negative polarity.

Furthermore, a driving means is provided so that the potential being applied to the nonlinear resistance element during a holding period is made equal to or within the threshold voltage of the nonlinear resistance element. Thus, the voltage applied to the nonlinear element during the holding period is reduced, an electron holding characteristic is improved and display unevenness and contrast are improved. Also, nonlinear elements with a lower threshold voltage and good controllability are used.
