Abstract: A liquid-crystal display apparatus has liquid-crystal display panels, in which scanning and signal electrodes are arranged in a matrix, and the number of scanning electrodes in divided into 1/N. A RAM has a video data storage capacity corresponding to an (N-1)/N field of the 1/N-divided liquid-crystal display panel. An electrode drive signal for driving the scanning electrodes selects an identical scanning electrode for each 1/N field, so that video data corresponding to a 1/N image from the RAM is distributed to be displayed on divided display regions.

Abstract: An IC card system uses at least one of the RESET, I/O, and CLOCK terminals of an IC card so as to serially and/or parallel input multivalue signals having different levels. The levels of the input signals are detected at a detector or detectors and outputs therefrom are compared at a comparator with specific codes prestored in level matrix of the IC card. If a coincidence between outputs obtained corresponding to the input signals and the specific codes is established, a test program stored in a test program ROM is started.

Abstract: An electronic musical instrument has a memory capable of storing musical tone waveform data therein. A read circuit reads out the musical tone waveform data from the memory and supplies the readout data to a musical tone generator. The musical tone generator generates a musical tone signal in accordance with the input musical tone waveform data, and outputs the musical tone signal. A write circuit writes new data in the memory at a timing different from the timing at which the read circuit reads out the musical tone waveform data from the memory. The write circuit partially updates the musical tone waveform data stored in the memory, and stores data of a played sound in part of the memory.

The supply of power to the IC card is renewed every time the IC card sends a request for an unit of data, within the period of time set in the time-measuring circuit. The supply of power is stopped when the IC card makes no request for an unit of data within the above-mentioned period of time.

Specific identification information stored in the memory is compared with identification information entered by the owner of an IC card. If the comparison result shows coincidence between the compared information, the owner enters another item of identification information. This information is compared with the corresponding identification data prestored in the memory. If the comparison result shows coincidence between them, it is then determined that the holder of the IC card is the rightful owner.
