In a plasma display panel, a partition wall 15 surrounds each of discharge cells to define the discharge cells. Each of the discharge cells is divided by a second transverse wall 15B into a display discharge cell C1 which is opposite transparent electrodes Xa, Ya of paired row electrodes X, Y to provide for a sustaining discharge; and an addressing discharge cell C2 which is opposite a bus electrode Yb of the row electrode Y to provide for an addressing discharge caused between the bus electrode Yb and a column electrode D. A clearance r is provided between the discharge cell C1 and the addressing discharge cell C2 for communication between the cells C1 and C2.

LPG storing cylinder (1) has a top portion fixed to a valve block (2) provided with a through hole (4) for attaching a gas take-out nozzle (3). The gas take-out nozzle (3) is attached to the through hole (4) as it is urged with an urging spring (6) for valve closing. A gas take-out passage (7) within the gas take-out nozzle (3) communicates with the nozzle attaching through hole (4) by a window hole (8). A sealing ring (10) is fitted into a portion where the window hole (8) is formed to shut off a communication between an interior area of the gas storing cylinder (1) and the gas take-out passage (7). A guide pipe (12) to communicate the interior area of the cylinder with a valve chamber (5) projects from an inner end wall of the valve block (2) into the interior area of the LPG storing cylinder (1).

A light guide panel and liquid crystal display device including a liquid crystal cell array, a light guide panel or plate disposed on a rear surface of the liquid crystal cell array, and a light source disposed at a lateral side of the light guide panel or plate. The light guide panel or plate has a light incident surface on which light rays emitted from the light source are incident, a light-transmissive surface through which the incident light rays exit the light guide panel or plate toward the liquid crystal cell array, and a plurality of reflecting slant portions for directing the incident light rays toward the light-transmissive surface, wherein the reflecting slant portions are constituted by convexes or concaves which are substantially rectangular in plan view and substantially trapezoidal in sectional view.
摘要:
Disclosed is an optical recording medium having recording film containing a photochromic material and a binder, in which the photochromic material is acid anhydride of diarylethene derivative and the binder is polycarbonate. Owing to this structure, the optical recording medium can reliably keep information recorded thereon even when the information is repeatedly reproduced.

A rewritable photochromic optical disk comprises a photochromic recording layer made of a dibenzothienyl ethene derivative, 1,2-di(2-cyano-3-benzothienyl)-1,2-dicyanoethene capable of assuming first and second states, the first state with a first absorption band transforming into the second state with a second absorption band by irradiating a first light beam of a first wavelength, and the second state transforming into the first state by irradiating a second light beam of a second wavelength in the second absorption band. This rewritable photochromic optical disk has a stability in the repeated recording and erasing information and a high thermal stability and capable of storage of information extended over a long period of time, in accordance with its higher quantum yield than that of the conventional dibenzothienyl ethene derivative so that the achromatic reaction takes place by irradiation of a low power laser beam.
摘要:
When information recording is conducted by converting a non-colored state of a recording film into a colored state, use is made of a recording light having a wavelength in such a range that an absorbance of the non-colored state is higher than an absorbance of the colored state. When information erasing is conducted by converting a non-colored state of a recording film into a colored state, use is made of an erasing light having a wavelength in such a range that an absorbance of the non-colored state of the recording film is higher than an absorbance of the colored state. Accordingly, the present invention has the advantage of a great change of color being exhibited in the recording film, thus enabling optimal recording and erasing of information.
