    摘要： A common electrode and an individual electrode are provided in plural pairs on a first transparent substrate, and recesses are formed in a second substrate in positions corresponding to the pairs of electrodes to define discharge cells of display cells. The display cells of a display panel can be individually driven on the cell-by-cell basis and the planar panel has a reduced thickness. A voltage pulse is applied to the individual electrode to reverse the polarity of wall charges accumulated on a dielectric layer, and a voltage pulse is then applied to the common electrode so that an electric field of the wall charges caused upon the reversal of the polarity is additionally applied. Thereby provided are a planar display panel which can set a large control margin in the display operation, ensure stable display, and present gradation display with high reliability and quality.

    摘要： A method of forming a groove having a desired cross section easily and rapidly, by making laser beam scan in the longitudinal direction of the groove. In the method, a laser beam 11 is irradiated to a work 15 to form a groove 16. When the longitudinal and the width direction of the groove is the x-axis and the y-axis, respectively, an intensity distribution of the laser beam in an irradiated region Q on the work is expressed by f(x, y). An integral of f(x, y) with respect to x, i.e., g(y), is proportional to a depth distribution of the groove 16, d(y), and the intensity distribution f(x, y) is formed by passing the laser beam 11 through a mask pattern 12a which has an appropriate transmission factor distribution. The groove 16 is formed by moving the region Q in the x-axis direction. The cross section of the groove 16 is determined by the mask pattern 12a. And the groove 16, having a desired cross section, is obtained in one scanning in the x-axis direction.

    摘要： A trick action type clock, wherein a dial plate which is arranged in front of ornaments is made of left and right side dial plates mating along a line passing through a center of rotation of the hands. A planetary gear mechanism actuates the left and right side dial plates so as to make them rotate and revolve around the center of rotation of the hands to produce an opening and closing motion. Therefore, the dial plate made of the two mating parts performs an opening and closing motion which produces a strong impression due to the surprising dynamic change.
