The present invention provides a recording material comprising a substrate and a recording layer thereon characterized in that the oxygen transmission rate of the substrate, as measured in accordance with Method B of JIS K 7126, is not greater than 50 cc/m.sup.2 /day. If necessary, a protective layer is formed on the recording layer. The substrate is composed of a sheet of base paper and a plastic film layer present at least on the side of the paper which faces a recording layer to be formed. The plastic film layer is appropriately selected from the group consisting of a polyester film, a polyvinylidene chloride film, a polycarbonate film, a polyvinylchloride film and a film of a random copolymer of ethylene and vinylalcohol. The recording material according to the present invention is excellent in the long-term preservation of images, fading resistance and light fastness.

The present invention provides a semiconductor integrated circuit for driving a light emitting panel such as an organic EL panel capable of displaying a picture with the optimum picture quality by changing a gray scale voltage and a gamma curve characteristic in accordance with brightness of the environment and specifications of a display used. A semiconductor integrated circuit for display driving is provided with a storing circuit such as a register or a ROM for storing a plurality of values for changing the amplitude of a gray scale voltage, and a storing circuit such as a register or a ROM for storing a plurality of values for changing the gamma curve characteristic. By selecting a value from a plurality of values in the storing circuit in accordance with an output of a photosensor and supplying the selected value to a gray scale voltage generation circuit, the gray scale voltage and the gamma curve characteristic can be dynamically changed.

In a method of transferring packets in a network for a parallel processor system handling a one-to-one transfer packet to be transferred from a processor to another processor and a broadcast packet to be transferred from a processor to a plurality of other processors, a transfer request of a broadcast packet is preferentially selected and a check is made to detect whether or not a plurality of processors specified as receivers are in a state in which the packet can be received. The broadcast packet is transferred to the processors found to be in the state in which the packet can be received. The packet transfer is delayed for the other processors in a state in which the packet cannot be received. Namely, only when the state of the processors is changed to the state in which the packet can be received, the broadcast packet is transferred thereto.

In the support member for photographic printing paper of the present invention, a white reflective layer is placed on a base material by coating and drying a coating composition, said coating composition contains a white pigment having titanium oxide as principal component and a binder having a copolymer of vinyl chloride - vinyl acetate and maleic acid anhydride soluble in organic solvent and having polymerization degree of 250 or more, said copolymer containing vinyl chloride, vinyl acetate and maleic acid anhydride by component ratio of 20-90 weight %: 5-50 weight %: 2-10 weight %. Thus, the support member can provide photographic image with high resolving power, has high bonding property with base material and silver halide emulsion layer, is easier to produce, and causes discoloring less frequently due to time or heat.
摘要:
A pressure-sensitive recording sheet is described. The sheet is comprised of a paper substrate which is treated with succinic acid derivatives having an alkenyl group or alkyl group containing from 4 to 18 carbon atoms, or salts thereof. This pressure-sensitive recording sheet is greatly reduced in the formation of fog which occurs in printing the sheet. Thus, it is very useful as no carbon paper.
摘要:
A method for measuring pressures which comprises allowing a material whose pressure is to be measured to press against a recording sheet to form a color image due to the pressure, and evaluating the changes in the optical color density of the color hue of the resulting color image on the recording sheet, the color image formation due to the pressure being effected by contacting a microcapsule layer containing a color former with a color developer layer under pressure.
