Abstract: PROBLEM TO BE SOLVED: To realize a complex multiplier which requires four multipliers in the conventional example by using three multipliers. SOLUTION: The sum and different of and between the real number value and imaginary number value of a first complex number are calculated by means of a first sum and difference operating circuit 11 and the sum and difference of and between the real and imaginary number values of a second complex number are calculated by means of a second sum and difference operating circuit 12. Then a first multiplier 13 multiplies one of the output signals for sum and difference of the first operating circuit 11 by one of the output signals for sum and difference of the second operating circuit 12 and a second multiplier multiplies the other of the output signals for sum and difference of the first operating circuit 11 by the other of the output signals for sum and difference of the second operating circuit 12.  A third sum and difference operating circuit 15 calculates the sum 4 and difference between the output signals of the first and second multipliers 13 and 14. A correction term operating circuit 16 multiplies the two real numbers obtained from the first and second sum and difference operating circuits 11 and 12 by each other and outputs a value obtained by correcting the real or imaginary number value of the output signal of the third sum and difference operating circuit 15 by performing addition and subtraction on the value as a complex-multiplied value.

Abstract: PURPOSE:To obtain a carbon dioxide sensor which has high reliability for measurement and a long life by applying generated electromotive force and reverse- polarity voltage to a gas sensing portion for a preset time before detecting the concentration of carbon dioxide. CONSTITUTION:In accordance with the first timing signal, a switching circuit section 23 connects the gas sensing portion of a carbon dioxide detecting section 21 to a d.c. voltage applying circuit section 24.

In this way, operation is made so as to cancel the activity change of Na2O, the decomposition disappearance of Na2CO3 and the entire surface coating with Na2O. If the third timing signal is issued with a delay equivalent to a preset relaxing time from the second timing signal to trap the generated electromotive force of the gas sensing portion as data through a CPU section 25 in accordance with this signal, the precise concentration of carbon dioxide not including errors due to drift can be detected.

Filed: 1989-10-18
Abstract: PURPOSE:To erase information by simple operation by controlling a switch operation sequence and a timer and executing function allocation such as operation start, ringing stop, LCD display, and the reading and erasing of message information only by two switches. CONSTITUTION:A control part 35 starts receiving operation by turning on the 1st switch 51 and stores received message information in a message memory 34. Then the control part 35 supplies the message information to a liquid crystal display device(LCD) controller 36 and supplies ringing start/stop information to a ringing waveform forming part 37 to allow an LCD and a speaker 7 to execute initial operation display. When the 2nd switch 52 is turned on, the control part 35 controls the LCD controller 36 to allow the LCD 5 to display the message information. After detecting the continuation of ON operation of the 2nd switch 52 for a fixed time, the control part 52 controls the memory 34 to erase the message information stored in the memory 34. Consequently the contents of the memory 34 can be erased by the operation procedure of the existing switches 51, 52.

Title: Driving of liquid crystal display
Inventor: IMAMURA YOICHI
IPC: H04N5/66
Filed: 1987-10-27
Abstract: PURPOSE: To reduce the generation of crosstalk and flickers and to provide a liquid crystal display device with higher quality by executing interlaced scanning in each electrode arranged on an equal position in grouped scanning electrodes in fixed order and scanning all the electrodes within a fixed period. CONSTITUTION: Every m (m>=4) adjacent electrodes out of all scanning electrodes are grouped, scanning electrodes arranged on an equal position, e.g. a 1st field from the 1st electrode up to (4n+m)th electrode, are scanned, and after inverting liquid crystal driving polarity, a (4n+m)th electrode, e.g. (4n+2)th electrode, is scanned to form a 1st frame. Even when effective voltage impressed to a liquid crystal panel is deviated from an ideal value, the deviation is corrected in a succeeding field. Although optical response frequency is reduced when the panel is observed from an oblique direction and flickers remarkably appear under a fluorescent lamp in a conventional method, this driving method can double the frequency even at the time of observing the panel from an oblique direction and can visually reduce flickers because of the dispersion of peaks.
