Abstract: A charging roller includes a conductive core, a resistive elastic layer disposed on the conductive core, and a surface layer disposed on the resistive elastic layer. The impedances of the resistive elastic layer and the surface layer measured at an environmental temperature of about 10° C. and a humidity of about 15% RH in a range of alternating voltage frequencies of an image-forming apparatus used satisfy: |ZE/(ZE+ZS)|?0.81 where ZE is the impedance of the resistive elastic layer, and ZS is the impedance of the surface layer.

Abstract: A shading decorative sheet comprises a transparent base layer having a back face and a front face opposing to the back face, which comprises a thermoplastic resin film, a decorative layer provided on said front face of the base layer, which has a gradation pattern at least in one direction, and an adhesive layer fixedly provided on said back face of the base layer, wherein said gradation pattern comprises an opaque region having a haze of at least 30% when measured according to ASTM D 1003-00 and a transparent region, and a ratio of the areas of the two regions is changed at least in one direction.

Abstract: A lubricant supply apparatus includes a pump for discharging lubricant. The lubricant is supplied onto two rows of floor plates arranged on a row of ties. Two tongue rails are mounted on the two rows of floor plates in such a manner as to slide on the floor plates. Times at which the pump is to start operating are preset in a schedule timer. The schedule timer informs a lubricant supply timer when the pump should start operating.

Abstract: The present invention provides a method for the recover of a solvent used in the production of a polyarylene sulfide according to which the deterioration of the solvent is low and the recovery rate is high, wherein a mixed liquid, mainly composed of the solvent used in the production of the polyarylene sulfide, and generated from the process of producing the polyarylene sulfide, is subjected to a flash evaporating operation to separate the mixed liquid into a flashed vapor (A) and a flashed residue (B), and then the flashed vapor is rectified (A).

Abstract: The present invention provides a method of recovering a lithium chloride, which comprises reacting a dihalogenated aromatic compound and an alkali metal sulfide and/or alkali metal hydrogen sulfide in a polar solvent under the pressure of lithium chloride, separating a solvent insoluble component from the resultant reaction mixture to obtain a solution, and calcinating a residue obtained by removing volatile substances from the resultant solution, as well as a method of recovering a lithium chloride, which comprises reacting a dihalogenated aromatic compound and an alkali metal sulfide and/or alkali metal hydrogen sulfide in a polar solvent under the pressure of lithium chloride, separating the granular polymer ingredient from the resultant reaction mixture subjecting the liquid suspension obtained by said separation to solid-liquid separation and calcinating the residue obtained by removing volatile substances from the resultant solution component.

Abstract: Disclosed is apparatus for treating polymers containing volatile matters and removing the volatile matters from the polymers, which comprises a polymer discharge device provided with heating means and adapted to discharge a polymer charged therein in the form of a strand or film and so forth, which device is mounted inside a decompression vessel or on a wall of the vessel.

Abstract: A centrifugal angular advance device for internal combustion engines is provided with a pair of weights and an advance plate engaged with the pair of weights for provision of an angular advance. Each of the pair of weights comprises a blank or integrated blanks and a drive pin secured to the blank or integrated blanks for driving the advance plate. The blank or integrated blanks is hardened after a bushing having no effect on the hardening has been provided in the hole of the blank or integrated blanks for the drive pin. The bushing is precisely finished by reaming with a reamer, then the drive pin is press-fitted into the bushing. Thus the weight is completed.
