摘要:
An image-forming system has an image-forming sheet, and a printer for forming an image on the sheet. The sheet has a sheet of paper, and a layer of microcapsule, coated over the paper sheet, that contains a plurality of microcapsules filled with a dye. A shell wall of each microcapsule is composed of a resin exhibiting a pressure/temperature characteristic such that, when each microcapsule is squashed under a predetermined pressure at a predetermined temperature, the dye seeps from the squashed microcapsule. The microcapsules are covered with an infrared absorbent coating that-absorbs infrared rays having a specific wavelength. The printer has a transparent glass plate, and a roller platen elastically pressed against the plate at the predetermined pressure, with the sheet being interposed between the plate and the platen. Further, the printer has an optical scanner for scanning the layer of microcapsules with an infrared beam having the specific wavelength, such that the microcapsules, irradiated by the infrared beam, are heated to the predetermined temperature.

An image transfer apparatus that records an image through selective heat and pressure application has an ink ribbon and a film disposed between a driving head and a flat platen. Color dyes of the ink ribbon are transferred to the film as the image. The image on the film is thus conveyed to a position for transferring the image to a recording sheet. The film and the recording sheet are pressed between a transfer roller and a conveyor roller with a pressure that sufficiently smooths unevenness in the surface of the recording sheet. A high quality image is thus recorded on the recording sheet regardless of the surface condition of the recording sheet.

In an image-forming system, an image-forming substrate is used, which has a sheet of paper, and a layer of microcapsules coated over the sheet of paper. The layer of microcapsules includes at least one type of microcapsules filled with an ink. A shell wall of each microcapsule is formed of resin, which exhibits a temperature/pressure characteristic such that each of the microcapsules is squashed under a predetermined pressure when being heated to a predetermined temperature, thereby discharging the dye out of the shell wall. A printer, having a roller platen and a thermal head, forms an image on the substrate. The platen locally exerts the pressure on the microcapsule layer. The thermal head selectively heats a localized area of the microcapsule layer, on which the pressure is exerted by the platen, to a temperature in accordance with an image-information data, such that the microcapsules in the microcapsule layer are selectively squashed and an image on the microcapsule layer.

The disclosed method of measuring the flow of a fluid with a porous particulate ceramic tracer and an optical instrument is characterized in that spherical particles having diameters in the range of 0.5 to 150 &mgr;m are used as the tracer. Inasmuch as the tracer particles for flow measurement are spherical, the sectional area of scattered light to be detected by an optical sensor means is constant regardless of the orientation of particles. Furthermore, spherical particles have no surface irregularities that might cause concatenation so that individual particles are not agglomerated in tracking a fluid flow, thus contributing to improved measurement accuracy.

A pressure-sensitive and heat-sensitive recording apparatus has a pre-coating container that pre-coats a recording sheet prior to a printing operation on the recording sheet. The pre-coating material container, ribbon cassette and an over-coating material container are provided in a recording head, while being movable in a printing direction lead by the pre-coating material container. The printed color-image is protected by an over-coating material dispensed from the trailing over-coating material container.

A producing apparatus of a film with through-holes includes a pair of stretching rollers which sandwich a film therebetween and stretch the film. The producing apparatus further includes a pair of punching rollers which sandwich the film therebetween and punch through-holes in the film. At least one of the punching rollers has projections formed on an outer surface thereof. The stretching rollers and the punching rollers are disposed so that the film stretched by the stretching rollers are fed to the punching rollers.

A plurality of thermal heads for different colors, are disposed in parallel in a line-printing direction, being offset with respect to each other in a transport direction along which an image-forming sheet is moved via a conveyer path. The image forming sheet is a pressure/temperature-sensitive sheet or a temperature-sensitive sheet. The thermal heads are moved in the line-printing direction. Adjacent-opposing ends of adjacent thermal heads are separated in the line-printing direction, and overlap in the transport direction. The thermal heads are controlled so as to simultaneously generate image-pixels on the image-forming sheet. The printing speed is high due to a plurality of colors being simultaneously printed. The thermal heads are used as part of pressure applying unit. The pressure applying unit is provided for selectively applying predetermined pressure to the micro-capsules, when the image-forming sheet is a pressure/temperature-sensitive sheet. The thermal heads can also be applied to a high-speed printing of a mono-chrome image on the temperature-sensitive sheet.

There is disclosed a vacuum insulation switch provided with a movable electrode, a stationary electrode and an earthing electrode, which are insulated from each other, in a vacuum container made of a conductive material which is earthed, and a switchgear using the same. Since the vacuum insulation, which is excellent in the insulation ability, is utilized, the switch is drastically miniaturized and the number of constituent parts are reduced, whereby the manufacturing cost of the switch and the switchgear can be decreased.

Using a thermal writing device, an image is drawn on an image-forming sheet that includes a base and a layer of microcapsules, coated over the base, containing microcapsules filled with a dye. The microcapsules are squashed under a predetermined pressure at a temperature falling in a predetermined temperature range. The device includes an elongated body, having a tip-end, designed to be grasped by a user's hand, a heater movably provided on the tip-end of the body, and a spring provided in the tip-end of the body. The spring is associated with the heater to be elastically biased such that, when the tip-end of the body is pressed against the sheet, the heater is depressed against an elastic-force of the spring, thereby exerting the predetermined pressure on the sheet. An electrical driver that electrically energizes the heater to heat to a temperature falling in the predetermined temperature range is also provided.
摘要:
An ink transfer printer comprises a thermal head that has an ink reservoir provided on a top surface of a housing and a film provided on a bottom surface of the housing. A space is formed by the film and the bottom surface. An ink passage is formed in the housing to communicate the ink reservoir with the space. Porous glaze is provided on the bottom surface to face the ink passage. Heating elements are provided on the porous glaze. The ink kept in the ink reservoir is supplied to the space through the ink passage and the porous glaze. The film has perforated pores, which are substantially closed to block the ink when the heating elements are not heated. When the heating elements are heated, the film is deformed to eject the ink through the pores.
