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).

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.

An aqueous dispersion coating material containing, as a film-forming constituent, an aqueous dispersion that can be obtained by contacting with an aqueous medium, a base-neutralized resin reaction product with an acid value of 10 to 30 which can be obtained by reacting a water-soluble epoxy-denatured alkyd resin with an epoxy resin in solid state at ordinary temperature and by adding and polymerizing at least a part of these resins and then neutralizing the resin reaction product with a base.Because this coating material has been emulsified in a translucent colloidal emulsion region with an aqueous medium, its finished appearance and corrosion resistance are superior and its structural viscosity can be controlled without damaging the storage stability through the addition of organic solvents, and the excellent finished appearance can also be obtained by atomization coating in addition to immersion coating, flow coating and the like, of vertical areas, and this coating material has applicability to a variety of coating methods.
