摘要： A device selectively supplying a high voltage and a ground level voltage to electrodes of an electroluminescent display panel. The voltage supply device includes a first and a second transistor connected in series, and outputs the high voltage upon turning on the first switching transistor and the ground level voltage upon turning on the second switching transistor. The device includes a circuit for selecting either an operation mode under which the device is normally operated with the high voltage or a test mode under which the device is tested under a low test voltage. The mode selection is performed by an external signal supplied to the device. Under the test mode, the switching transistors are turned on with a low gate voltage by operation of a circuit built in the device. Accordingly, the voltage supply device normally operated under the high voltage is easily tested under the low test voltage.

摘要： A lock release apparatus in a vehicle includes a vehicle unit and a portable device, for an exchange of the first and second reference signals transmitted therebetween from the portable device through human body of the driver toward the right and left hands of the driver onto the first and second interfaces. The signals received by the interfaces are used to set the first and second determination conditions. At a time of a shift lever operation, an interface on a shift lever is used to receive the first determination signal for determining the first determination condition, together with the second determination signal from the other interface for releasing the lock of the shift lever.

摘要： A display panel having plural capacitive elements such as electroluminescent elements is driven by an integrated circuit connected between the display panel and a power source. A pair of power transistors such as MOSFETs is connected between the power source and the integrated circuit. The capacitive elements are selectively charged and discharged by operating switching elements in the integrated circuit. The pair of transistors disposed separately from the integrated circuit is turned on or off after the switching elements in the integrated circuit are closed, so that the switching loss only occurs in the transistors outside the integrated circuit, thereby suppressing temperature rise in the integrated circuit. A pair of resistors may be used in place of the transistors to divide a voltage supplied to the capacitive elements between the resistors and the integrated driver circuit. A step-recycle circuit including a condenser for recycling a part of energy stored in the capacitive elements may be further connected between the power source and the pair of transistors, to further reduce power consumption in the integrated circuit.

摘要： All two-character chains including two general characters and all three-character chains including one special character between two general characters are detected from a registration character string in which a large number of special characters not having any meaning are frequently arranged, or all two-character chains including two general or symbolic characters are detected from a converted registration character string produced by changing each special character of the registration character string to one type of symbolic character determined in correspondence to one general character adjacent to the special character. Also, occurrence frequencies of the general or symbolic characters of each chain are counted and stored in a recording medium with the registration character chains. When a retrieval character chain is input, occurrence frequencies of particular character chains corresponding to all retrieval character chains detected from the retrieval character string in the same manner are read out from the recording medium and are collated with each other, and a particular character string agreeing with the retrieval character chain is retrieved from the registration character string. Because an occurrence frequency of any special character is not counted or the special characters are changed to various types of symbolic characters, a recording area required for the occurrence frequencies of the registration character chains can be reduced.
