  • Publication number: 20100201249
    Abstract: A plasma display panel in which projections are formed in grooves between partitions and phosphor layers are provided on the projections so as to increase the area where phosphor adheres and thereby to increase the luminance. A couple of substrates are opposed to each other to form a discharge space. Band-like partitions partitioning the discharge space are arranged on the back or front substrate. Wall-like projections lower than the partitions and high enough to increase the area where phosphor layers are formed are provided in the region where the discharge space is formed in the long grooves between the partitions or around the discharge space. Phosphor layers are formed in the grooves between the partitions including the wall-like projections. A method for producing such a plasma display panel is also disclosed.

  • Patent number: 6713959
    Abstract: A plasma display panel and method of producing same, in which projections are formed in grooves between partitions and phosphor layers are provided on the projections so as to increase the area where phosphor adheres and thereby to increase the luminance. A pair of substrates, opposed to each other, form a discharge space. Band-like partitions partitioning the discharge space are arranged on one of the back and front substrates. Wall-like projections, lower than the partitions but high enough to increase the area where phosphor layers are formed, are provided in the region where the discharge space is formed in the long grooves between the partitions or around the discharge space. Phosphor layers are formed in the grooves between the partitions including the wall-like projections.

  • Patent number: 6650062
    Abstract: A PDP having a novel cell structure that is superior in light emission efficiency is provided. A conductive film to be display electrodes X and Y is formed on side portions of a wall so that a main surface that contributes to discharge in the display electrode X is disposed so as to be opposed to a main surface of the neighboring display electrode Y via a gas space. A power supplying portion straddling plural cells in the display electrodes X and Y is provided on the upper surface of the wall. The display electrodes X and Y are covered with a dielectric layer that is thin at the side portion and thick at the top portion of the wall.

  • Patent number: 5084598
    Abstract: An electric switch for a power tool, comprising: a slider slidably received in a switch casing along a longitudinal direction, a handle provided in the grip of the power tool for manually actuating the slider along the longitudinal direction; a plurality of fixed contact pieces arranged in an internal bottom surface of the switch casing and provided with contact surfaces located substantially in a same plane; and a plurality of moveable contact pieces arranged in the bottom surface of the slider and urged toward the fixed contact pieces by spring members so as to selectively contact at least some of the contact surfaces of the fixed contact pieces. The contact portions of this switch achieve various conductive states by planar arrangement and movement of the contact pieces, the component parts can be fitted into a small switch casing, particularly having a small height.
