    Abstract: Row electrodes Xi (i=1 to n) are arranged over portions close to right and left ends of a PDP, and column electrodes Wj (j=1 to m) are arranged over portions close to upper and lower ends thereof to grade-separately intersect with the row electrodes Xi. The column electrodes Wj and Wm+1−j are connected in common. Row electrodes YL1 to YLn extending over a portion close to the left end and a portion close to the center and row electrodes YR1 to YRn extending over a portion close to the right end and a portion close to the center are arranged alternately with row electrodes X1 to Xn. A scan pulse Vax1 is successively applied to the row electrodes Xi and a voltage Vaw1 based on image data is applied to each column electrode Wj in synchronization with the application of the pulse Vax1 in a first address period. In this period, a subscan pulse Vay1 is applied to the row electrodes YL1 to YLn while the row electrodes YR1 to YRn are set to a ground potential. In a second address period, the voltages applied to the aforementioned row electrodes YL1 to YLn and the row electrodes YR1 to YRn are exchanged. Thus, reduction of the cost for a plasma display device is attained by reducing the number of driving ICs for the column electrodes.

    Abstract: In a host interface circuit performing data transmission/reception between an external host controller and a device connected to the external host controller, the external host controller generates, as external addresses to be supplied to the connected device, first addresses corresponding to the respective internal addresses in an internal storage space of the connected device, and a specific second address corresponding to internal addresses of a series of areas in the internal storage space; and the host interface circuit includes a first address conversion circuit for converting the first addresses into the internal addresses in the internal storage space, and a second address conversion circuit for converting the specific second address into the internal addresses in the internal storage space; and the specific second address is used when the external host controller makes continuous access to the serial areas in the internal storage space of the connected device. Therefore, the external host controller can make continuous access to a series of areas in the internal storage space of the connected device by using the specific address, without using DMA, between the external host controller and the host interface circuit. As the result, power consumption is reduced, and complexity in software processing is reduced.

    Abstract: Column electrodes W1 to Wm are arranged on the side of a rear glass substrate along a first direction D1 at regular intervals. Row electrodes X1 to Xn and Y1 to Yn include (a) strip bus electrodes Xb1 to Xbn and Yb1 to Ybn alternately arranged on a surface of a front glass substrate closer to discharge spaces at regular pitches to extend in a second direction D2 and (b) square transparent electrodes Xt and Yt having ends connected to the bus electrodes Xb1 to Xbn and Yb1 to Ybn respectively. The transparent electrodes Xt and Yt alternately extend into single ones of unit areas AR adjacent to each other in the first direction D1 through the bus electrodes Xbi and Ybi connected with the ends thereof. The unit areas AR are separated into discharge cells C having discharge gaps defined by opposite edges of the transparent electrodes Xt and Yt and non-discharge cells NC having no discharge gaps. The discharge gaps C are not adjacent to each other in the first and second directions D1 and D2. Thus provided is an AC-PDP capable of suppressing/avoiding false discharge.

    Abstract: A piezoelectric component prevents development of a short circuit between separate electrodes of a piezoelectric element and provides a high level of connection reliability. The piezoelectric component includes a piezoelectric element utilizing a longitudinal oscillation mode and being mounted on a mounting substrate. The piezoelectric element has on one main surface thereof a first electrode and a second electrode formed by dividing electrode material via longitudinally extending linear grooves and, on the other main surface, a third electrode. Conductive support members are secured to node sections of the first and second electrodes so as to be spaced apart from each other with respect to the longitudinal dimension of the piezoelectric substrate. The support members are adhered to and secured to pattern electrodes of the mounting substrate by conductive adhesive.
