    摘要： Flanges are pressed into opposite ends of a photoreceptor drum. A noncontact charging roller is arranged so as to face, but have no direct contact with, the photoreceptor drum. On both end portions of the noncontact charging roller, spacers are provided for maintaing a gap between the photoreceptor drum and the noncontact charging roller. The spacers are of tape form and wound around the noncontact charging roller. Winding positions of the spacers are distant by more than an effective projection length of each of the flanges from respective opposite ends of the charging roller.

    摘要： A nitride semiconductor device used chiefly as an LD and an LED element. In order to improve the output and to decrease Vf, the device is given either a three-layer structure in which a nitride semiconductor layer doped with n-type impurities serving as an n-type contact layer where an n-electrode is formed is sandwiched between undoped nitride semiconductor layers; or a superlattice structure of nitride. The n-type contact layer has a carrier concentration exceeding 3×1010 cm3, and the resistivity can be lowered below 8×10−3Ωcm.

    摘要： The present removing system has a feature to remove a left-over toner that is accumulated on a brush that touches a left-over toner on a photoreceptor. More specifically, the present removing system is so arranged that an alternating voltage (superimposing voltage) on which a positive direct current voltage is superimposed is applied onto a conductive brush in accordance with a user's instruction. With this arrangement, even if a positively electrified left-over toner is accumulated on the conductive brush, it is possible to remove the positively electrified left-over toner accumulated on the conductive brush, because a voltage value (positive) applied on the conductive brush in a moment is large. Moreover, because a voltage of the conductive brush becomes negative in a moment, it is possible to remove a negatively electrified left-over toner attached on the conductive brush.

    摘要： A metal-working oil composition comprises as essential components thereof (a) one or more lube-oil components selected from the group consisting of oils, fats, mineral oils and fatty acid esters; and (b) one or more water-soluble polymer compounds selected from the group consisting of homopolymers of acrylic amide, copolymers of acrylic amide and other monomers and salts of the homopolymers and copolymers, the molecular weights of which homopolymers, copolymers and salts fall within the range of from 1,000 to 10,000,000.The incorporation of the specific water-soluble compound allows a lube-oil component to disperse stably as large droplets in water and hence, several advantages including thick and strong lubricating film suitable for use under severe machining conditions can be obtained.
