IPC: F04C25/02
Filed: 1983-03-18
Abstract: PURPOSE:To prevent overheat while to reduce weight and to eliminate precise working, by forming coarse plastic face on the surface of metal shaft through coating or primary molding then injection molding plastic body while integrally surrounding them. CONSTITUTION:It is injection molded by heat-resistant and chemical resistant resin such as PPS (polyphenylene sulfide) then PPS resin 10 is applied thinly over the outercircumference of a shaft 8 having a recess 9 and mounted on a dies 11 thereafter PPS resin is pressure injected as shown by arrow 12 to injection mold a rotor 13. Consequently difficulty due to heat cycle and inner stress is prevented and the weight is reduced. While conductivity of approximately 10<4>ohm/cm<2> of surface resistance is provided to said resin to prevent overheat of rotor 13 under load operation while to prevent difficulty due to electrostatic adhesion of dust.

Title: Production of water-in-oil emulsion of water-soluble polymer
Inventor: SHIBAHARA YASUO
IPC: C08L33/04
Filed: 1979-04-12
Abstract: PURPOSE: To produce title emulsion having excellent stability, by adding a water- soluble organic acid to an emulsion prepared either by polymerizing a solution comprising an amide group-containing vinyl monomer, water, a surfactant, etc., and then, hydrolyzing part of the amide groups contained in the resulting polymer or by polymerizing the solution after adding thereto a radical initiator.  
     CONSTITUTION: An emulsion comprising an amide group-containing vinyl monomer, water, surfactant and a hydrophobic solvent is converted into either (a) a water-in-oil emulsion of an anionic vinyl polymer by polymerizing the emulsion into an water-in-oil emulsion of the polymer and adding thereto an alkali thereby to hydrolyze part of the amide groups contained in the polymer, or (b) a water-in-oil emulsion of a nonionic or anionic vinyl polymer by polymerizing the starting emulsion with a radical initiator under alkaline conditions. Then, the emulsion (a) or (b) is adjusted to pH7 or below by the addition of a water-soluble organic acid, such as lactic acid, malic acid or citric acid. Thus, there is obtained title emulsion useful as a coagulating agent or a chemical for paper making.

Title: Emitting light quantity adjusting method for printer
Inventor: MATSUKI NOBUYUKI
IPC: G03G15/04
Filed: 1990-02-27
Abstract: PURPOSE:To adjust a potential for controlling the emitting light quantity of this printer by comparing the output density of a printed out sheet with that of a sheet printed out a reference emitting light quantity. CONSTITUTION:After a photosensitive body 3 is uniformly electrostatically charged by a charge casotron 5 as a photosensitive drum 2 is rotated, it is irradiated with light beams by a fluorescent display tube 6 to form a latent image. The output density of a printed out image is compared with the sample printed sheet of the reference emitting light quantity at the time of a normal drum potential. When the output density of a test printed sheet is different from that of the sample printing sheet as reference, the anode voltage of the fluorescent display tube 6 is adjusted, so that the emitting light quantity is controlled. Thus, the emitting light quantity of the printer can be easily and properly adjusted even in a market.

Title: Argentic oxide cell
Inventor: ASADA AKIRA
IPC: H01M4/62
Filed: 1982-03-20
Abstract: PURPOSE:To improve the degree of molding as well as to facilitate the fabrication of an anode, by modifying an argentic oxide particle surface with grease which disperses polytetrafluoroethylene in ethylene trifluoride oil. CONSTITUTION:Adding a solvent made up of grease, carbon tetrachloride, trichlorethylene, hydrocarbon fluoride genera, etc., to argentic oxide, this compound is stirred and then the argentic oxide and grease well mixed and kneaded. As the amount of the said grease, it is 0.5-5% (wt%, and so forth) to the argentic oxide, particularly 1% or so desirable. In this connection, in case the argentic oxide is mixed, it will do when the said grease is added to the whole positive pole active material within the abovementioned range. And, as for such a solvent as carbon tetrachloride and the like, it may be done only when it is so added to such a degree as taking on a slurry state as a whole. Likewise, as for mixing and kneading time, the longer the better but because of a problem from the work efficient standpoint, generally it takes place within the range of 0.2-2hr. After kneading is over, the kneaded compound is dried up within the limits of that the ethylene trifluoride oil in the grease does not escape in vapor and the solvent consisting of carbon tetrachloride, etc., is evaporated instead.
