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.

A pressure-sensitive recording sheet is described, comprising a base paper having coated thereon a color developer solution wherein said base paper has been sizepressed or coated with a cationic sizing agent.
摘要:
A pressure sensitive recording sheet which uses specified raw paper as a paper support. The raw paper has a fiber length distribution such that the total amount of a percentage by weight of a 24 mesh residue and that of a 42 mesh residue is 65% or less by weight of the total residue as determined in accordance with the fiber classification method (JIS P-8207) and thereby both decreased process fog and increased color density of the developed images are attained.
摘要:
A heat-sensitive recording paper for producing recorded images in combination with a thermal head is disclosed. The recording density and resolving power of the image are improved due to the use of a base paper prepared using a pulp having a Canadian standard freeness above 400 cc as the support for the recording paper.
摘要:
An audio and video recording and reproduction apparatus includes an audio signal switch section for outputting one of a first audio signal having a first volume level and a second audio signal having a second volume level by a switching operation; and a mute section for muting the first audio signal which is output from the audio signal switch section when the audio signal switch section switches the second audio signal to the first audio signal.
摘要:
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.
摘要:
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.
摘要:
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.
