摘要:
An ink donor sheet comprising a porous sheet and a heat-fusible ink layer formed on it is disclosed. The ink layer has such temperature-dependent gradation characteristics that it remains solid at ordinary temperatures and when it is heated to a certain temperature its viscosity is suddenly decreased and upon further heating, the viscosity is decreased gradually. The ink donor sheet is capable of producing halftones in the images it creates.

A copying machine includes an optical sensor of the line scanning type for converting an image into electrical signals, and a thermal recording head controlled in accordance with the image signals. The platen moves with respect to the read unit and the read unit will read in both forward and reverse directions of the platen, and the magnification value can be varied. The total width of energized heating elements and the movement length and speed of the platen may be controlled in accordance with the size of the original. The total number of heating elements energized at any one time is limited, and the machine includes input and output terminals for sending image information externally and for receiving and recording image information other than directly from the read unit.

A heat-transfer recording medium is described, which includes a substrate and a two color transfer layer on the substrate, wherein the two color transfer layer contains a solid heat-sensitive ink which melts or sublimates at a relatively low temperature and is transferred to a recording paper as a predetermined color, and a heat-sensitive color-forming ink dispersed in the solid heat-sensitive ink, which melts or sublimates at a relatively high temperature, and is transferred to the recording paper in a color different from the above color.
摘要:
The heat-generating resistors in a heat-sensitive recording head are preheated, during the serial-to-parallel conversion of the video input signals and prior to the initiation of the recording cycle, to pre-heat the recording medium to a temperature 10.degree. to 15.degree. C. less than the temperature at which recording occurs, thereby reducing the minimum recording time required to produce a high density, high quality image on the recording medium.

The thermorecording medium is comprised of a support having coated thereon a plurality of heat-sensitive ink materials each having a different melting point. The ink materials can be formed on strip supports wound on rolls which can be utilized by passing the medium close to a finely focused heat source while the inked side of the support is in contact with a recording sheet. The medium may be in the form of an endless belt which can be rotated within a device in such a manner that the medium is continuously reused.
摘要:
A multicolor recording apparatus includes a number of recording sections for applying different colors of inks. A main transport path travels through all recording sections, while bypass paths are provided for recording sheets which are to be recorded monochromatically, for example, so that any one or more of the recording sections may be bypassed. To eliminate wastage of ink donor sheet, the web containing the solid ink is not conveyed in recording sections bypassed by the sheet.
摘要:
A multi-color thermal transfer recorder has a thermal recording head, a roll disposed opposite to the thermal recording head, and an ink donor sheet having two or more layers of single-color ink different in color from each other, the length of each ink layer being equal to the length of the outer circumference of the opposing roll.

A heat-sensitive recording head including an insulating substrate, an array of heat generating elements, a plurality of leads alternately arranged on both sides of the array of heat generating elements on the insulating substrate with the heat generating elements interposed between the leads. Lead wires are connected to predetermined ones of the leads either directly or through diodes. The lead wires are arranged in a matrix format and heat generating elements are coupled in blocks with the number of blocks being equal to half the number of common drive terminals provided. With the number of blocks represented by n, the average value of the resistances of the heat generating elements by r, and the maximum variation of the resistances by .+-.r, ##EQU1## is established.

The present invention is to provide a new surfactant that can be used as an emulsifier excellent in emulsion stability and texture in use and as a cleanser excellent in cleansing power and texture in use and having low skin irritation. A surfactant consisting of a compound represented by the below-described general formula (1). Y—O-(EO)l-(AO)m-(EO)n-X (1) (In the formula, AO represents an oxyalkylene group having 3 to 4 carbon atoms; m is the average addition mole number of the oxyalkylene group and satisfies 5≦m≦100. EO represents an oxyethylene group; l and n are the average addition mole numbers of the oxyethylene groups and satisfy 0≦l≦4 and 0≦n≦4. Either X or Y or both are a functional group represented by —SO3M, —COOM, —HPO3M, —(CH2)q—SO3M, or —(CH2)q—COO, wherein M is a hydrogen ion or a monovalent inorganic or organic cation, and q is the number of carbon atoms of the linked alkylene group and satisfies 1≦q≦4. When either X or Y is the above-described functional group, the other one can be a hydrogen atom, a methyl group, or an ethyl group.)
