Abstract: A recording medium has a substrate and a first color developing layer, a heat insulating layer and a second color developing layer laminated on the substrate in this order. The first color developing layer develops a first color at a temperature not less than a first threshold value. The second color developing layer develops a second color that is different from the first color at a temperature not less than a second threshold value that is higher than the first threshold value. The heat insulating layer has a first heat insulating layer of a first heat conductivity and a second heat insulating layer of a second heat conductivity that is higher than the first heat conductivity, which are laminated in a second direction orthogonal to a first direction in which the first color developing layer, the heat insulating layer, and the second color developing layer are laminated on the substrate.

Abstract: A method of manufacturing a print head includes forming a jet stack having an array of jets, arranging an array of transducers on the jet stack such that each transducer in the array of transducers corresponds to each jet in the array of jets, embossing a flexible circuit substrate having contact pads such that the contact pads extend out of a plane of the flexible circuit substrate, and arranging the flexible circuit substrate such that the contact pads electrically connect to at least some of the transducers in the array of transducers.

Abstract: A non-impact recording method is provided in which 3 to 4 or more copying sheets can be made through a non-impact system and further a small-sized printer which can be installed in portable type information terminal equipment can be formed. A non-impact recording method is also provided in which when electricity is applied between separate electrodes and a common electrode oppositely contacted with each other and arranged against both surfaces of a conductive recording medium, a recording image is formed by heat energy generated by the conductive recording media, wherein a plurality of the conductive recording media are overlapped with each other and volume resistivities of each of the overlapped conductive recording media are substantially the same to each other or decreased as they may move toward the common electrode.

Abstract: A conduction recording head forms an image on a recording sheet by connecting return path electrodes and recording electrodes conductively through a printing and recording medium. Recording electrodes, a drive circuit and connector electrodes are all disposed integrally on a flexible insulating film as a main head part which is disposed on a rigid support member through an elastic member.

Abstract: A high-speed image forming method and apparatus is capable of directly controlling a toner by the force of an energy beam. Selected toner particles in a mass of toner adhering to the surface of a transparent drum are irradiated with a laser beam emitted by a laser disposed within the transparent drum and controlled for scanning according to image information. The laser beam separates the selected toner particles from the transparent drum by the force it produces on the particles, and then the separated toner particles are moved to a paper sheet by the force of an electric field produced by a developing electrode. Each toner particle need only be irradiated with the light for a comparatively short period of time, so that an image can be formed at high speed.

Abstract: In a thermal recording apparatus, a thermal head heats an ink sheet to transfer ink to a recording medium such as paper. Even when recording on a low-smoothness plain paper, an image free of voids can be obtained. The apparatus is equipped with a mechanism for generating an electric field between the ink sheet and the recording medium. Due to this electric field, the ink particles liquified by the thermal head fly and are transferred to the recording medium.

Abstract: A selection circuit for an electro-thermal printer with a resistance-type ribbon includes a print unit, a current collection electrode, a memory, and a print control unit. The resistance-type inking ribbon that is moved relatively transfers ink particles from an ink layer into areas on a receiving medium when an associated thermal resistance in a resistance layer is heated. A voltage drop that is caused by a total current and by a variance of the resistances is measured through a non-selective current path (feedback layer) in the resistance inking ribbon by a measurement electrode that is disposed close to the print head. That causes a constant voltage source which has a reference voltage input to apply feed voltage to the electrodes that are temporarily connected therewith through a switching unit.

Abstract: A print head applies electrical energy to an electrically resistive and grounded transfer ribbon bearing heat transferable dye, during sliding pressure contact and relative movement between the head and ribbon, for resistive heating of the dye to a transfer temperature for transfer to a receiver to form images of selective pixel size thereon. The head has a row of electrodes with end faces and an electrically non-conductive substrate with an end face, the end faces lying in a contact plane for contact with the ribbon. A groove in the substrate end face separates such end face from the electrode end faces. The width of the groove is sufficient to inhibit heat transfer at the groove from the ribbon to the substrate for controlling the dye amount heated to transfer temperature adjacent the groove during the relative movement and in turn the image pixel size.
