摘要： A multiplexed driving method of an optical switching element employing ferroelectric liquid crystal with a negative dielectric anisotropy including signal electrodes S i ) and common signal electrodes (C₁, C₂) arranged in matrix and a ferroelectric liquid crystal layer disposed therebetween so as to constitute pixels (A i , B i ) at the respective facing portions of the signal electrodes (S i ) and the common signal electrodes (C₁, C₂) comprising a step of applying a common writing signal voltage to one of the common signal electrode to select pixels to which information be written, simultaneously applying a common status holding AC signal voltage to the other common signal electrodes covering non-selected pixels and simultaneously applying one of two signal pulses with opposite polarities to the signal electrodes, whereby resultant information writing voltages formed in combination of the common writing signal voltage and the signal pulses, which are enough to determine the orientation of the ferroelectric liquid crystal molecules, are applied on the selected pixels and resultant AC status holding voltage formed in combination of the common status holding AC signal voltage and the signal pulses which determine the limited bias voltage for the resultant AC voltage are applied on the non-selected pixels.

摘要： In a thermal transfer printer of the type wherein pigment or dye on the thermal transfer paper is transferred onto the recording paper by means of a thermal print head (10), a plurality of current pulses having a sufficiently small time width are seriated closely to produce a contiguous current supplied to each of thermal elements (11) of the print head. It is detected whether any current pulse flows at least in one of the thermal elements, and the current conducting operation is terminated when none of the thermal elements is found to conduct the current pulse. The printer can terminate the recording operation in the course of any line that none of the thermal elements conducts the current any longer, and proceed to the recording operation for the next line, whereby the printing time can be reduced.

摘要： Disclosed are a method and an apparatus for reducing vibrations generated in a stationary induction apparatus (1) by detecting the vibration and by applying a vibration applying force capable of suppressing the detected vibrations to the stationary induction apparatus by at least one vibration applying device (4a to 4f), in which the phase and amplitude of the vibration applying force of the vibration applying device are successively and reparatedly adjusted so as to decrease the sum of squares of the respective amplitudes of vibration detected by the vibration sensors. A calculation for obtaining the sum of squares of the detected amplitudes of vibration and the control of the phase and amplitude of the vibration applying force based upon the calculated sum of squares may be carried out in accordance with a programm stored in a microcomputer.
