摘要： A display device structure comprising a casing, a display panel placed in the casing, a transparent covering and vibrating plate member on the front side of the display panel and an actuator for the plate member. The covering and vibrating plate member is carried on the casing through an elastic member interposed between the peripheral portion of the plate member and the casing. By this arrangement the plate member is capable of effectively generating sound outward upon reception of vibrating force from the actuator.

摘要： Disclosed is a transparent piezoelectric transducer comprising, at least, a transparent vibrator and at least one plate of a piezoelectric ceramic material sandwiched between a pair of transparent electrodes, said transparent vibrator being disposed so as to be vibrated by the piezoelectric ceramic material plate, said piezoelectric ceramic material being a ceramic material which is represented by a formula:Pb.sub.1-x La.sub.x (Zr.sub.y Ti.sub.z).sub.1-x/4 0.sub.3where x and y/z are set within a region enclosed with lines successively coupling points a-b-c-d-e-a in a phase diagram (FIG. 2 of the accompanying drawings) in which a ratio (y/z) between PbZrO.sub.3 and PbTiO.sub.3 is taken on an axis of abscissas, while an La concentration (x) is taken on an axis of ordinates (where x=8.4 and y/z=65/35 at a, x=6 and y/z=55.5/44.5 at b, x=6 and y/z=50/50 at c, x=12 and y/z=50/50 at d, and x=9 and y/z=65/35 at e). The transparent transducer is excellent in both the transparency and the electroacoustic response.

摘要： A thin timepiece comprising a flattened casing, a display unit, a diaphragm having its peripheral portion carried by the casing to generate sound, a piezoelectric element mounted on the diaphragm and a module for driving the display unit and the piezoelectric element. The diaphragm and the piezoelectric element are formed ring-like so that the space in the central hole of the ring-like diaphragm and piezoelectric element is used for a part of the occupation space of the electric cell in the casing and that renewal of an electric cell is facilitated by the provision of the space for the cell in the diaphragm and the piezoelectric element.

摘要： A liquid crystal display device having a structural arrangement that a plurality of liquid crystal layers each for displaying a pattern are piled up and a pair of polarizers are provided above an uppermost liquid crystal layer and below a lowermost liquid crystal layer, is disclosed in which a polarizer is interposed between adjacent liquid crystal layers in such a manner that adjacent ones of the polarizers are different in direction of transmission axis from each other, in order to eliminate a white on black portion caused by an overlap of the patterns and to thereby reduce the area of a display region; or in which a white on black portion caused by an overlap of the patterns is used as a display portion to form a display pattern having a predetermined shape and to open up new possibilities for color display.
