Abstract:
A rolling, sliding member is formed from a steel containing 0.9 wt. % to 1.1 wt. % C, 0.5 wt. % to 3.0 wt. % Si, 0.05 wt. % to 0.5 wt. % Mn, 2.0 wt. % to 5.0 wt. % Cr, and 0.05 wt. % to 0.5 wt. % Mo, the balance being Fe and unavoidable impurities. The average grain size of spheroidal carbide is 0.6 μm or less, and the spheroidal carbide content is 6.0% or less as percent area. In a toroidal-type continuously variable transmission, the rolling, sliding member is used as at least either disks 4 and 9 each having a concave raceway surface on a side surface thereof, or rollers 16 rolling on raceway surfaces 4b and 9b of the disks 4 and 9. The toroidal-type continuously variable transmission using the rolling, sliding member of the present invention exhibits long life.

Abstract:
To provide a technology for making it possible to control enable/disable of an IC card function provided in a mobile device. A mobile device including an IC card unit for executing an IC card function, and a communication unit for carrying out communication through a radio telephone line detects a voltage of a battery unit for supplying an electric power to each of the IC card unit and the communication unit, judges whether or not the IC card function can be used in accordance with the detected voltage value, and issues an enable/disable instruction to the IC card unit in accordance with the Judgment results.
Abstract:
A value information management system includes, a value exchange card, user terminal, and management server. The value exchange card stores value information representing the value of a product/service purchased through a network, together with ID information. The user terminal includes a medium information reading unit which reads the information of the value exchange card and an information transmitting unit which transmits the information read by the medium information reading unit through the network. The management server includes an information storage management unit which receives the information transmitted from the user terminal and stores/manages ID information and value information in association with each other, and a value information search unit which searches for the value information corresponding to the ID information in response to an inquiry sent through the network and returns the value information. A value information management method is also disclosed.

A lid (8) for opening and closing the external light admitting window (6) is provided on the viewfinder barrel. (1)
Abstract:
A bidirectional nonlinear resistor for use as a nonlinear active element having a highly insulating organic film formed on a first conductor by polymerizing in an electrolytic solution containing a supporting electrolyte and a soluble organic compound, and a second conductor identical or not identical in kind with the first conductor formed on the organic film is provided. An active matrix substrate including a plurality of the bidirectional nonlinear resistor elements may be used to have a liquid crystal display panel. In a preferred embodiment, the electrolytic solution includes an alkali hydroxide as a supporting electrolyte so that dopant need not be removed after formation of the film. The electrolytic solution which is electrolytically polymerized to form the insulating organic film includes a monomer, preferably pyrrole, pyrrole derivatives, phenol or phenol derivatives, dissolved in an electrolytic solution.
Abstract:
Thin film devices including a film of a functional organic material, inorganic material or mixtures which are either insoluble or sparingly soluble in water, and deposited by electroplating. Particles of the functional material are dispersed in a micelle solution of a surfactant which is oxidizable and reducible by electrolysis in a colloidal state. Thin film devices prepared include color filters, optical recording media, electrochemical photoreceptors, nonlinear switching elements, and other devices requiring thin films of materials which are substantially insoluble in water.
Abstract:
A solid-state imaging device having a scanning circuit and a photoconductive film formed in layers on a semiconductor substrate, and a process for forming the same, wherein high resolution with substantially no color mixing is attained. An electrode layer is formed over the semiconductor substrate for providing the plural electrodes, and a photoconductive film is formed over the electrode layer. A first transparent electrode is produced over the photoconductive film, after which a resist pattern is formed on the first transparent electrode layer corresponding to the pixels. The first transparent layer and the photoconductive film are etched according to the resist pattern to spatially isolate adjacent pixels in the first transparent layer and the photoconductive film. Adjacent pixels are isolated by etching, using the resist pattern, that part of the electrode layer on which are disposed the first transparent electrode layer and the photoconductive film between isolated pixels.
