Abstract: The inkjet recording apparatus comprises: a printing device including a print head which discharges ink droplets onto a recording medium to perform printing, the print head having discharge ports through which the ink droplets are discharged; a liquid removal device which absorbs droplets deposited on an ink discharge surface of the print head in which the ink discharge ports are formed; and a deposit removal device which wipes away matter deposited on the ink discharge surface.

Abstract: The inkjet recording head comprises: a nozzle which discharges ink; a liquid-repellent treatment part which repels the ink; and a sealing liquid affinity treatment part that has an affinity with sealing liquid used for sealing off the ink inside the nozzle from outside air, wherein the liquid-repellent treatment part and the sealing liquid affinity treatment part are provided on a discharge surface in which the discharge port of the nozzle is formed.

Abstract: The image recording apparatus records images on a recording medium by performing relative movement of the recording medium and a recording head provided with image recording elements, and controlling driving of the image recording elements according to image data, and the apparatus comprises: a recording medium size determination device which determines a size of the recording medium to be used; a magnification setting device which sets magnification in order to generate an image larger than the size of recording medium according to input image data and the size of the recording medium determined by the recording medium size determination device; a first image processing device which generates image data with a size larger than the size of the recording medium from the input image data in accordance with the magnification set by the magnification setting device; a recording medium determination device which is disposed further upstream from the recording head in a relative movement direction of the recording

Abstract: The present invention provides a surface treatment apparatus containing a sheet heating unit for heating a sheet, a sheet cooling unit for cooling the sheet.

Abstract: A photosensitive material containing a photosensitive silver halide and an organic silver salt and capable of forming an image, which corresponds to a latent image recorded on the photosensitive material through exposure, when the photosensitive material is heated, is utilized for forming an image. The photosensitive material, on which the latent image has been recorded, is heated, and the image corresponding to the latent image is formed with the heating on the photosensitive material. The image is read out from the heat-developed photosensitive material, and an image signal having thus been obtained is subjected to image processing for forming a digital image signal, from which the image is capable of being reproduced.

Abstract: A winding core member of a winding core is divided along an axial direction into a first main body, a second main body and a third main body. Projections which are formed at the respective main bodies can fit into cam grooves of cams provided in the winding core member. For this reason, when the cams are rotated, inner peripheral walls of the cam grooves are engaged with the projections, and the main bodies are pulled in inwardly in a radial direction so as to approach each other, so that an outer diameter of the winding core is decreased. Therefore, after a sheet material is or sheet materials are wound in layers around an outer periphery of the winding core, the winding core can be pulled out from the sheet material(s) easily.

Abstract: A take-up device of an image forming sheet material, in which a plurality of sheet materials used for formation of images is sequentially wound, comprises: a core member formed in the shape of a cylinder and supported rotatably, the core member being provided such that the plurality of sheet materials can be wound around an outer periphery of the core member; an endless belt entrained across a plurality of rollers and moved in a circulating manner in a predetermined direction with an outer periphery of the endless belt contacting by pressure an outer periphery of the core member so as to rotate the core member and the endless belt nipping the sheet material together with the core member to sequentially wind the plurality of sheet materials around the core member; and tension maintaining means for maintaining tension of the endless belt substantially fixedly irrespective of a change of a winding diameter of the sheet material wound around the core member.

Abstract: The present invention discloses a full-automatic flash welding apparatus wherein the trailing edge of the preceding strip and the leading edge of the succeeding strip are automatically accurately positioned, rigidly clamped and simultaneously cut off, the new trailing and leading edges are automatically machined and then butt welded, and thereafter the flash on the upper and lower surfaces of the joined strips is automatically removed.

Abstract: A butt welding device wherein the trailing edge of a first or preceding strip and the leading edge of a second or succeeding strip are clamped in position, simultaneously cut off, and joined together by flash butt welding and thereafter the flash and upset are removed by machining.
