Patent JP-H0651612-A (JP)
Title: Image forming device
Inventor: ISHIHARA TORU
IPC: G03G21/10
Filed: 1992-07-30
Abstract: PURPOSE:To hardly produce a positive afterimage in an image forming device where a cleaningless process and ozonefree process are combined. CONSTITUTION:Developer remaining on the surface of an image carrier (photosensitive drum) 1 after finishing transfer is recovered after finishing electrostatic charging and before starting the transfer. A rotating member(electrostatic charging roller) 2 is disposed in contact with the image carrier 1 so as to uniformly electrostatically charge the surface of the carrier 1 to generate surface potential. The rotating member 2 is rotated by a rotating means, the rotating direction D of the member 2 is reversed to the rotating direction A of the carrier 1, and the surface speed of the member 2 is set higher than that of the carrier 1. Therefore, the residual developer on the surface of the carrier 1 is loosened and restrictive force to the carrier 1 is made weak. At such a time, the vicinity of a spot where the residual developer is present is uniformly and sufficiently electrostatically charged. In the case of forming the member 2 of conductive foaming body, the surface shape peculiar to the conductive foaming body effectively acts to move the residual developer.

Title: Uninterruptive power supply
Inventor: KANEKO KOICHI
IPC: H02J9/06
Filed: 1988-08-18
Abstract: PURPOSE:To prevent loss due to the forward voltage drop of a diode by shorting the diode between a storage battery and an inverter, at the time of AC input power interruption. CONSTITUTION:When an interruption is generated on an AC power source 1, DC voltage due to a diode rectifier 3 is lowered, below the DC voltage of a storage battery 10. Then, a diode 12 passes current, and DC power is continuously fed from the storage battery 10. In this case, when the service interruption is generated on the AC power source 1, then an electromagnetic contactor 5 is worked so that the excitation of an operating coil may be released and the diode 12 may be short-circuited. Accordingly, a state that the power of the storage battery 10 is fed to an inverter 7 via the diode 12, is changed to a state that the power is fed to the inverter 7 via the main contact of the electromagnetic contactor 5. A time for the power of the storage battery to be fed to the inverter 7 via the diode 12 is a very short time while the excitation of the electromagnetic contactor 5 is released and the diode 12 is short- circuited. As a result, a loss due to the forward voltage drop of the diode is eliminated.

Title: Recovery of pure hydrocarbon from hydrocarbon mixture containing aromatic compound and nonaromatic compound
Inventor: DONNERMEYER STEFAN
IPC: C10G7/08
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To simply recover a pure hydrocarbon at a slight cost by treating a hydrocarbon mixture with a high content of an aromatic compound with an extractive distillation column under specific conditions. SOLUTION: The extractive distillation of a hydrocarbon mixture containing an aromatic and a nonaromatic compound, especially a hydrocarbon mixture with a high content of the aromatic compound is carried out in an extractive distillation column 1. In the process, the second partial stream of a selective solvent is fed from the column top above the first solvent feeding parts 4 and 10 of the extractive distillation column 1 and one or more N-substituted morpholines are used as the selective solvent to take out the nonaromatic compound as a raffinate from the top 7 of the extractive distillation column 1. The aromatic compound and the selective solvent as extracts are further taken out of the bottom 5 of the extractive distillation column 1.  When the pure hydrocarbon is recovered, the second partial stream of the selective solvent is passed through the second solvent feeding part 10 above the first solvent feeding part 4 from the upper part 2 of the extractive distillation column 1 thereinto. The amount of the solvent fed as the second partial stream is smaller than 50% of the total amount of the solvent fed as the first and the second partial streams.
