The average levels of the potential impressed at the time of non-selection are the same regardless of all lighting or all non- lighting signals. Namely, the polarities of the potential difference formed by the potential in the selection period of the selection signal impressed to the first signal line which is the Y line and the potential of the display signal impressed to the second signal line which is the X line are inverted between the first signal lines adjacent to each other and, therefore, the polarities of the voltages applied to the liquid crystals for pixels are inverted with a short period.

Title: Device and method for extracting feature of character
Inventor: AOKI TAKAO
IPC: G06K9/46
Filed: 1990-11-30
Abstract: PURPOSE:To improve the recognition ratio of characters by measuring the average thickness of respective characters and deciding reference width in stroke end point decision concerning the respective characters. CONSTITUTION:An average character thickness measurement part 5 measures the average line width of the character to extract the feature, and a reference value 30 is decided for extracting the stroke end point based on the measured value.

IPC: H05B6/68
Filed: 1990-11-30
Abstract: PURPOSE:To prevent abnormal heating and wasteful energy consumption by detecting the inclination of temperature change in accordance with detected temperature and outputting a stop signal when the inclination of the temperature change tends to an increase, to stop applying driving voltage to a magnetron. CONSTITUTION:Driving voltage is applied from a power supply device 10 to a magnetron 9 by tuning on a power supply to emit microwaves into an oven for induction-heating a heated material under rotating condition. After induction heating is continued until moisture is evacuated from the heated material to lead to no load, the temperature of the magnetron 9 becomes higher sharply. The temperature of the magnetron 9 is detected by a temperature detecting means 11 and the inclination of the temperature change is detected by an inclination detecting means 12 in accordance with the detected temperature. When the temperature of the magnetron 9 is higher sharply and the inclination of the temperature change tends to an increase, a stop signal is sent to a stopping means 13 to stop the microwave oscillation of the magnetron 9. It is thus possible to prevent the abnormal heating and the energy wasteful consumption of the magnetron 9.

IPC: G06F3/05
Filed: 1991-12-13
Abstract: PURPOSE:To conform sampled data to the actual value of analog data satisfactorily in a device which samples data at finite time from the analog data changing periodically. CONSTITUTION:It is judged S01 whether or not a sampling interval taun elapses after sampling last time is executed.
