摘要:
A photosensitive element comprising a support carrying photosensitive silver halide grains in a substantially predetermined spaced array and methods for forming such photosensitive elements.
摘要:
An optical information storage medium comprising a thin, optically darkenable film containing silver, lead, chlorine and oxygen, produced by vapor-depositing AgCl and PbO in specified proportions on a substrate for the film, is described.
摘要:
Disclosed is a pattern exposure method for conducting an overlay exposure to a base pattern previously formed by using electron beam, which has the steps of: 1) dividing a group of patterns formed on the base pattern into arbitrary regions; 2) calculating an area density of the base pattern in each of the arbitrary regions; 3) generating a pattern according to the area density; 4) conducting sub-exposure using the pattern; and 5) conducting main exposure to expose a desired pattern.
摘要:
An ultraviolet-sensitive optical information recording material comprising doped silver chloride and tin oxide which exhibits high ultraviolet darkening sensitivity and good resistance to darkening or bleaching by visible light, and a method for optically recording information in permanent, optically-readable form in such a material by direct writing without chemical development, are described.
摘要:
A planographic printing plate material comprising a support and a light sensitive layer provided on the support, the light-sensitive layer being composed of (A) an inorganic material; (B) at least one metal and/or metal compound [(A)/(B) are capable of reacting with each other upon application of electromagnetic radiation] and (C) an organic compound capable of affecting the reaction between the inorganic material (A) and the metal and/or metal compound (B), wherein the inorganic material (A), the metal or metal compound (B), and the organic compound (C) are in contact with each other. When the light-sensitive layer is exposed to electromagnetic radiation, a difference in the hydrophilic or oleophilic nature of the exposed areas and the unexposed areas results, whereby a planographic printing plate is obtained which can be mounted on a printing machine and printed without any other treatments.
摘要:
Microelectronic circuits are produced by evaporating a photosensitive compound such as a silver halide onto a chip which is then exposed to radiation such as light, or an electron beam whose motion may be controlled by a computer or similar device. The chip is then developed leaving behind the metallic conductive circuit, and the undeveloped portion is removed preferably by heating.
