Abstract: In a renewing apparatus, a thermal transfer recording medium is made to be used plural times by simple configuration although such a recording medium must be thrown away in the prior art, and the running cost in the printing can be significantly reduced. The apparatus has coating means for applying a thermal transfer recording material including at least one of a photopolymerizing monomer and a photopolymerizing polymer and a coloring agent to a substrate, means for sending the thermal transfer recording medium and means for irradiating light onto the recording material.

Abstract: The invention provides an electrophotographic printer wherein a toner unit and the entire apparatus can be reduced in size and the degree of freedom in designing can be achieved and besides possible deterioration of a photosensitive member can be prevented with certainty. A toner unit (3) in which toner power (2) is stored is disposed in the proximity of an outer periphery of a photosensitive belt (13) mounted for rotation. An LED head (5) is disposed on the rear face side of the photosensitive belt (13) while a developing roll (6) for causing toner power (2) to adhere to an electrostatic latent image to form a visible toner image and a cleaning roll (17) for removing and recovering remaining toner powder (2) of the photosensitive belt (13) are disposed in the toner unit (3). The cleaning roll (17) is formed from a magnet roll (18) and a sleeve (19) covering over an outer periphery of the magnet roll (18).

Abstract: An image forming method and apparatus using an electronic photographic technology to form an image on a recording medium is configured to deposit toner on the entire surface of a toner carrier then reduce the adhesion corresponding to an image to be formed among toner deposited on the toner carrier before transferring the toner corresponding to the image to the recording medium.

Abstract: Disclosed is a cleaning system for an image forming apparatus wherein the cleaning performance thereof will not be deteriorated by, will be substantially free from a change of the environment therearound and damage to a photosensitive member of the image forming apparatus is minimized in order to improve the life of the photosensitive member. The cleaning system comprises a conductive cleaning brush for slidably contacting with the photosensitive member to remove toner powder remaining on the photosensitive member.

Abstract: A double-side printer having a printer body including a print head disposed oppositely to a platen, a sheet conveying unit mounted in the printer body and including a sheet supplying unit for sequentially supplying sheets stacked on a sheet supply tray one by one to a printing position between the print head of the printer body and the platen, and a sheet exhausting unit for stacking and exhausting the sheet from the printing position to an exhausted sheet tray comprising belt-like latent image forming means narrower than the width of the sheet, a pair of transferring units for transferring toner image formed on the latent image forming means reversely to one another to the sheet, and an electrophotographic processing unit having a pair of sheet passages for inserting the sheet to pass the sheet through the transferring units, arranged between the sheet supplying unit and the sheet exhausting unit of the sheet conveying unit, a fixing unit disposed out of the electrostatic processing unit for fixing the toner

Abstract: A certain amount of a starting calcarious material is added to an aluminum smelting residue, the mixture is smelted or semi-smelted, air is blown to the smelted or semi-smelted product to oxidize A/N, and the smelted or semi-smelted product is finely pulverized to obtain a low-lime aluminous cement.An excellent refractory aluminous cement can be prepared according to this method.

Abstract: A heat-resistant thermosetting resin composition is obtained by reaction with each other of an N,N'-bis-imide of unsaturated dicarboxylic acid (A), a cyanuric or isocyanuric acid or derivatives thereof (B), and at least one compound (C) selected from the group consisting of tetracarboxylic acid diimide, hydantoin and derivatives thereof, and barbituric acid and derivatives thereof. This resin composition has excellent heat-resistance and workability, and is employed for the use of a molding, laminated sheet, adhesive, etc.

Abstract: A process for the manufacture of aluminous cement from aluminum smelting residue and the novel resulting cement are provided. According to the process, a mixture of predetermined amounts of aluminum smelting residue, limestone, aluminum siliceous clay, and, if necessary, fluorite and manganese ore for the acceleration of oxidation, is prepared and the mixture is finely crushed and then burned at temperatures between 1,300.degree. C and 1,500.degree. C to form a clinker which is then powdered to produce an aluminous cement of excellent quality. The product contains no harmful chemical compositions that tend to become a source of public hazards such as air or water pollution.
