摘要:
A hot melt ink which is applicable to an ink jet printing system where the hot melt ink is jetted out to a printing medium to form an image on the printing medium includes a binder which contains a hot melt composition; a coloring material which is dispersed in the binder; and a photo-curing composition. The binder as a dispersion medium is dispersed in the photo-curing composition in the form of grains and a surface of the hot melt ink is covered with the photo-curing composition when the hot melt ink is fixed on the printing medium. An ink jet printing apparatus includes a jetting device which jets the above hot melt ink melted by heat out to a printing medium to draw an image on the printing medium; and a light source for irradiating the hot melt ink on the printing medium which is jetted out from the jetting device to cure the photo-curing composition.

A device for forming an image with a laser beam is disclosed. The device comprises a laser, means for on-off modulating a laser beam, means for converting a wavelength of the laser beam generated by the laser and means for scanning the laser beam. With means for converting a wavelength of the laser beam, the laser which generates a laser beam, the wavelength of which does not directly meet the requirements, may be adopted to form an image.

When a mobile data communication device is rocked due to an input/output operation, a rotary shaft of a generator coupled with a weight is rotated, and power is generated. The generated power is stored in a capacitor. The power stored in the capacitor is controlled to constant voltage by a voltage stabilizing circuit and is supplied to a control circuit. In the control circuit, based on information inputted in a pointing device by supplied power, data are transmitted and received with an external data processing device through an infrared data transmitting/receiving device. Alternatively, power may be supplied from the outside of the mobile data communication device by electromagnetic induction. According to the above-mentioned configuration, not using a battery or a wire system, the mobile data communication device is capable of easily supplying power.
摘要:
An image recording device wherein an image is recorded on a photo-sensitive recording medium and said image is once formed as a light-shield image before recorded on the photo-sensitive recording medium. The device comprises light-shield image forming means for forming the light-shield image in a reduced size with respect to the image to be recorded, and enlarged image recording means for recording an image corresponding to the light-shield image in an enlarged size on the photo-sensitive recording medium.

A resistance heating element member formed with a resistor member on a polyimide film or resin sheet is fixed to the inner circumferential surface of a roller drum by blow-molding with a heat-resistant resin member. The resistor member includes a metal foil and meanders several times in a predetermined belt-like or serpentine pattern, and electrically contacts slide electrodes arranged on the roller at each side of the roller.

The present invention provides a life detecting system that accurately detects the end of the useful life of a process unit used in electrophotographic printers. The life detecting system comprises a RAM that stores a count of the number of driving pulses generated at an exposure unit and a ROM that stores a predetermined reference count that represents the useful life of the process unit in terms of a driving pulse count. The system indicates that the end of the useful life of the process unit has been reached when it determines that the count stored in the RAM is greater than or equal to the predetermined reference count stored in the ROM.
摘要:
A tracking servo device for changing a position on an optical storage disk, at which the storage disk is irradiated by a light beam. The servo device is responsive to a tracking error signal indicative of a deviation of the irradiated position on the disk with respect to a recording track provided on the disk. The tracking servo device includes an optical deflector element having a waveguide disposed in a path of the light beam, for guiding the light beam therethrough toward a surface of the optical storage disk, so as to deflect the light beam during propagation thereof through the waveguide. The device further has a deflection control arrangement for controlling an angle of deflection of the light beam by the optical deflector element, based on the tracking error signal.
