Abstract: PURPOSE: To prevent the crack of a dielectric sheet and to shorten the time for evacuating the inside of a hermetically sealed chamber to vacuum, etc., by using plural columnar independent ribs disposed in ineffective regions as struts for the dielectric sheet and forming the spacings thereof as flow passages for gas. CONSTITUTION: Effective pixel regions EA are constituted in the parts of display electrodes 32 not covered with cover glass 39 of a plasma address display device 1 formed by joining plasma substrate glass and thin sheet glass which is the dielectric sheet by square annular frit seals 35. The peripheral parts exclusive of the effective pixel regions EA in the hermetic sealing chamber 36 are formed as the ineffective regions IV which do not affect screen display. The many columnar independent ribs 40 in these ineffective regions are arranged apart prescribed intervals in the state of holding the ribs between the dielectric sheet and the plasma substrate glass. The spacings between the independent ribs 40 constitute the flow passages for the gas. Rapid suction is made possible when the inside of the hermetic sealing chamber 36 is evacuated to vacuum from a vent hole 37. Diffusion time is made shorter as well in a mercury expansion stage after gas sealing.

Abstract: PROBLEM TO BE SOLVED: To improve efficiency of degassing processing of a dielectric layer formed for an AC drive type plasma address display device. SOLUTION: The plasma address display device has a layered structure in which a display cell D and a plasma cell P provided with rows of discharge channels 4 on a transparent substrate 1 are mutually layered. The plasma cell is line-at-a-time scanned by exciting plasma discharge by sequentially applying a selection pulse across a pair of discharge electrodes 6 allotted to each discharge channel 4 and coated with the transparent dielectric layer 5, while an image is displayed by applying an image signal to each signal electrode 11 of the display cell D in synchronization with the line-at-a-time scanning. The manufacture of this device comprises an electrode process for forming the discharge electrodes 6 on the transparent substrate 1, a coating process for coating the discharge electrodes 6 with a paste containing a transparent dielectric material layered thereon, and a baking process for forming the transparent dielectric layer 5 on the discharge electrodes 6 by baking the applied paste in a vacuum atmosphere. Vacuum baking accelerates degassing of the dielectric layer.

Abstract: PROBLEM TO BE SOLVED: To efficiently wash a thin sheet glass with a thickness of at most 0.1mm without breaking. SOLUTION: A glass washing apparatus is basically provided with a washing tank 1 in which a washing liq. is filled and a holding tool for holding a thin sheet glass 2 with a thickness of at most 0.1mm and immersing it into the washing tank 1. When a rocking mechanism is fitted on this, washing is performed by rocking the thin sheet glass 2 only in the plane direction (X and Y) without rocking it in the thickness direction (Z) in the washing tank 1. In addition, when a stirring mechanism is fitted, washing is performed by making the washing liq. flow only in the direction (X and Y) being parallel to the plane without generating substantially a flow component in the vertical direction (Z) to the plane (X and Y) of the thin sheet glass. In addition, when a spraying mechanism is fitted, washing is performed by spraying the washing liq. only in the direction (X and Y) being parallel to the plane without including substantially a spray component in the vertical direction (Z) to the plane (X and Y) of the thin sheet glass.
