Title: Electrophotographic photoreceptor
Inventor: EBINE TOSHIHIRO
IPC: G03G5/14
Filed: 1993-06-18
Abstract: PURPOSE:To obtain an electrophotographic photoreceptor showing rapid rising for electrification in a low temp. and low humidity environment and capable of obtaining excellent picture image quality even in the initial region for printing by subjecting the body to two kinds of hole sealing treatment with vapor and nickel acetate. CONSTITUTION:After anodic oxidation of the surface of a conductive supporting body, the body is subjected to two kinds of hole sealing treatment with vapor and nickel acetate. Then, a photoconductive layer is formed to obtain the electrophotographic photoreceptor. By this method, slow rising for electrification in a low temp. and low humidity environment is avoided, and the obtd. photosensitive body has good rising property for electrification. Otherwise, after anodic oxidation of the surface, the supporting body is dyed with a water-soluble dye and further subjected to two kinds of hole sealing treatment with vapor and nickel acetate. By this method, reflected light from the substrate of the electrophotographic photoreceptor is suppressed. As a result, interference fringes on a printed picture image can be eliminated without decreasing other characteristics.

IPC: G03G15/09
Filed: 1989-06-10
Abstract: PURPOSE:To prevent picture quality from decreasing owing to the scattering of toner by providing a toner conveying member for magnetic toner with a multipolar low magnetic field layer and an electric field curtain generating layer. CONSTITUTION:The toner conveying member 20 for the magnetic toner is provided with the multipolar magnetic field layer 22 and electric field curtain generating layer 23. Therefore, even if the toner is scattered when supplied to an image carrier such as a photosensitive body, the toner is attracted to the multipolar low magnetic field layer 22 through the operation of the magnetic field curtain of the electric field curtain generating layer provided to the toner conveying member 20 and its scattering is suppressed. Consequently, an image never fogs and the image of high quality which is stable for a long period is obtained.

Title: Cooling method for metallic powder at reduction annealing thereof
Inventor: YAMATO SENSUKE
IPC: B22F1/00
Filed: 1986-06-26
Abstract: PURPOSE:To shorten the time for cooling metallic powder and to obtain the metallic powder for powder metallurgy having good compressibility by subjecting the metallic powder to slow cooling at a specific cooling rate in the temp. range where the compressibility is affected at the time of cooling the metallic powder after reduction annealing. CONSTITUTION:The raw material for the carbon contg. metallic powder is subjected to the quick cooling treatment in the temp. range from the reduction temp. to 800 deg.C where the compressibility is not affected at the time of cooling said material after the reduction annealing. The material is then slowly cooled at <=250 deg./hr cooling rate in the reduced pressure state of about <=20Torr between 800-400 deg.C of the temp. range where the compressibility is affected. The metallic powder is successively subjected to the quick cooling again at <=400 deg.C. The diffusion of the heat from the central part packed with the steel powder to the surface part is satisfactorily executed by the above-mentioned slow cooling treatment. The temp. over the entire part of the steel powder is thus uniformized and the quick cooling strain in the quickly cooled surface part is relieved. The molding having the good compressibility is obtd. if such metallic powder is used.

Abstract: PROBLEM TO BE SOLVED: To compensate the lowering of the temperature of a reforming reaction part, when a load is suddenly increased to suddenly increase necessary heat quantity, in an electric automobile, etc. SOLUTION: In a reformer 10, wherein an outer tube member 20 is arranged so that into which an inner tube member 30 can penetrate, a combustion gas is supplied to and passes the inner tube member 20, and a heat exchanger 15, for supplying heat quantity, is assembled to the inner tube member 30; the wall material of the inner tube member 30 is made hollow in the inside of the outer tube member 20, and a heat accumulating material 31b, such as LiNO3 having a melting point in a reaction temperature band of 200-300 degrees in the case of methanol reforming, is housed in the hollow portion. Sufficient heat quantity is supplied previously to the heat accumulating material 31b, to melt the material 31b to make it a liquid phase.  When the sudden increase of a reforming fuel gas is needed, despite delay is caused in supplying heat quantity by the combustion gas supplied from the outer tube member 20, the latent heat is diverged when the heat accumulating material 31b is phase- transferred into a solid phase, thereby sufficiently meeting heat quantity needed for reforming.
