Title: Detector for failure in separation of transfer paper in copying machine
Inventor: KUBOTA YOUICHI
IPC: G03G15/14
Filed: 1981-09-17
Abstract: PURPOSE:To improve the sensitivity in detecting the failure in sepn. of transfer paper by providing a sensor for surface potential which detects the failure in sepn. of transfer paper in accordance with the surface potential of a photoreceptor changing according to the presence or absence of the transfer paper after the end of transferring and separating stages. CONSTITUTION:A sensor 11 for surface potential facing a photosensitive drum 1 is provided between a separating and conveying belt 6 and a cleaning unit 7. When the failure in sepn. wherein transfer paper 9 which is transferred with images fails to be separated from the drum 1 despite passing through the belt 6 arises, the surface potential of the drum is detected while the paper 9 is held wrapped thereon, and the detected surface potential differs from the surface potential of the drum 1 in a normal time and is lower than the same; therefore, said potential is judged as failure in sepn. by a CPU control part 18. Since the influence of the surface, etc. of the photoreceptor is not received, the sensitivity in detecting the failure in sepn. of the transfer paper is improved.

Title: Patterned matting and production thereof
Inventor: OMOTO ISAMU
IPC: D04H1/559
Filed: 1989-06-09
Abstract: PURPOSE:To impart an adhesive effect and patterning effect to the matting in one stage by laminating an upper fiber layer and lower fiber layer consisting of materials different from each other, via a non-woven low melting hot melt fabric inserted therebetween, and embossing the laminate from above. CONSTITUTION:For example, the moquette formed by using polyester fibers is used as the upper layer. On the other hand, the needle punch felt formed by subjecting, for example, a fiber web of 500g/m<2> METSUKE consisting of 100% polyester fibers (250 deg.C m.p.) of 6 denier to needling alternately from above and below is used as the lower fiber layer. The non-woven low melting hot melt fabric (120 deg.C m.p.) of 50g/m<2> METSUKE consisting of modified polyester fibers is interposed and superposed between these two layers and the layers are tentatively laminated. The laminated fiber layers are placed in an oven and are heated at and for 200 deg.CX1min to melt the non-woven low melting hot melt fabric, by which the upper and lower fiber layers are welded. The laminate is thereafter subjected to the embossing for about 30 seconds at ordinary temp. from above by means of a patterned mold. The embossed patterns are thus formed on the surface of the fiber layers and the patterned matting is obtd.

IPC: H01M10/46
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To limit a power loss and eliminate the necessity of an expensive tracing adjustor by providing a battery charger with a feedback loop which detects the present battery voltage and monitors an instantaneous power loss of a pass device and generates a current controlling signal for charging a battery pack of the system. SOLUTION: A first feedback loop which passes a charge controller 150 determines a desired current value based on the present battery voltage, the present ambient temperature, and information from a data storage 123 of a battery pack 101. The current is sent to a second feedback loop provided with a power controller 103. In the case that the desired current causes an excessive power loss of the pass device 104, the power controller 103 reduces the current and generates a current controlling signal. The charge controller 150 calculates an absolute maximum value and a short-time maximum power loss of the pass device 104 in collaboration with the power controller 103 and controls the current so that it may not exceed the maximum value whatever the conditions of an unadjusted DC transformer 100 are.

Abstract: PURPOSE: To prepare developer composition having high developing activity when applied to a recording material by precipitating the hydrated silica/ hydrated alumina composite in the presence of an inorganic pigment, e.g. kaolin, talc, or calcined kaolin. CONSTITUTION: A sol is formed by gradually adding a metal silicate solution to a solution of an aluminum salt which is initially at a pH below 4 until the pH of the resulting mixture is approximately 4. Alkali is gradually added to the sol to raise the pH to approximately 7, thereby to induce further precipitation and gel the sol of hydrated silica/hydrated alumina composite or further gel the gel. The resulting product is separated from the aqueous medium and then washed to remove the dissolved salts. The washed product is dried, and the particle size is reduced.

Filed: 1993-06-21
Abstract: PURPOSE:To prevent the development of uneven solidified mark and ripped surface by providing electrically conductive refractory in parallel with a roll axis on a side dam so as to be positioned below the molten metal surface in a well. CONSTITUTION:The side dam 2 is brought into close contact with the end surfaces of the rolls 1a, 1b and the molten metal is supplied from a pouring nozzle 3 to form the well 4. The molten metal is cooled with the rolls 1a, 1b to form the solidified shells 5a, 5b and these shells are discharged as a cast slab 6. A decelerating member 7 composed of the electrically conductive refractory is fitted to the side dam 2 in parallel with the roll axis. The decelerating member 7 is constituted in a box-state and of porous plate to decelerate the molten metal flowing speed. Since the decelerating member 7 is arranged not to project on the molten metal surface, the molten metal is not cooled with air, etc., and undersirable solidified shell is not developed. The decelerating member 7 has good electric conductivity, and the electrically conductive heating can be executed, and preheating with a gas burner is unnecessary before starting the casting.
