Abstract: PROBLEM TO BE SOLVED: To prevent a photoreceptor from being stained, to prevent toner from adhering, and to reduce the coefficient of friction by forming a surface layer on the surface of a conductive rubber layer and making the main material of the surface layer polyester polyurethane resin whose glass transition temperature is specified. SOLUTION: As to this intermediate transfer member 20b; the surface layer 202 is formed on the surface of the conductive rubber layer 201, and the main material of the layer 202 is the polyester polyurethane resin whose glass transition temperature is -20 deg.C to 20 deg.C. An elastic body which is obtained by adding a conductive material, etc., to a suitable rubber material so that conductivity is imparted is used as the layer 201. In this case, it is desirable that the resistance value of the member is adjusted to be an intermediate resistance area without mixing the conductive material to the layer 202 by using the polyester polyurethane resin whose volume resistivity is 10 to 10 Ω.cm as the one for forming the layer 202. Thus, the resistance value of the member can be easily adjusted to the intermediate resistance area.

Abstract: PURPOSE:To obtain a color sensor having simple constitution, inexpensive and having sufficient sensitivity in a visible light region, by combining two or more of org. photo-electric cells using org. dyes having different absorption spectra. CONSTITUTION:A transparent conductive film 2 is provided on the back surface of a glass substrate 1 and the first org. photo-electric cell consisting of a metal layer composed of Al or N-type semiconductor layer 31 composed of CdS, a dye (a) layer 41 and a back surface electrode 51 and the second org. photo-electric cell consisting of a metal layer or semiconductor layer 32, a dye (2) layer 42 and a back surface electrode 52 are together provided on said conductive film 2. Further, lead frames 61-63 are provided. By this constitution, dyes having different absorption spectra are different in the photoelectric converting capacity to a certain wavelength and difference in photo-electromotive force appears. Therefore, by forming two or more of org. photo-electric cells using different dyes to combine both of them, a color can be judged from the difference between the electromotive forces of the individual photo-electric cells to light having a certain wavelength and an inexpensive color sensor having sufficient sensitivity in a visible light region is obtained.

Abstract: PURPOSE:A high-performance battery with a practical size is easily and surely manufactured by reducing the pressure in a battery case, and injecting and charging the decompressed battery case with an electrolyte. CONSTITUTION:First of all, a three way cock 4 is operated to open a passage 5 and close a passage 9 and a vacuum pump 6 is operated to reduce the pressure in a battery case 1 until it reaches the prescribed reduced pressure. When the pressure reaches the prescribed pressure the three way cock 4 is changed over to close the passage 5 and open the passage 9. Thus, a electrolyte 7 charged in a container 8 is made not to flow to the vacuum pump 6 side, and it is immediately injected into the battery case 1.

Abstract: PURPOSE:To increase the coulomb efficiency and the cycle life in high capacity charge-discharge by forming a negative electrode in a nonaqueous secondary battery with a specified alloy in which magnesium is contained. CONSTITUTION:A nonaqueous secondary battery is formed with a nonaqueous electrolyte containing an alkali metal ion, a positive electrode capable of charge- discharge, and a negative electrode which absorbs an alkali metal ion during charge and desorbs the alkali metal ion absorbed into an electrolyte during discharge. The negative electrode is formed with an alloy of one or more metals selected from a group of zinc, tin, antimony, lead, bismuth, and thallium, and magnesium, or an alloy obtained by adding an alkali metal to the above alloy. Thereby, the coulomb efficiency of the secondary battery is remarkably increased, and decrease in capacity and coulomb efficiency caused by repeated charge-discharge is retarded to increase the cycle life.

Abstract: PROBLEM TO BE SOLVED: To provide a toner carrier capable of surely and stably obtaining a high-quality image without causing image change due to time passage or image irregularity, at the time of consecutive printing or in partial solid image printing without causing white image fogging. SOLUTION: As for this toner carrier, the absolute value of surface potential attenuating speed attained until 0.2 seconds elapse after imparting charge in the case of electrifying the surface of the toner carrier by applying 8 kV voltage to a corona discharger arranged at the distance of 1 mm from the surface thereof so that corona discharge generated is >=0.1 [V/sec]. The toner carrier in this method is a roller obtained by forming a semiconductive layer 3 on the outer periphery of a good conductive shaft 2 and further forming a resin covering layer 3a on the layer 3 as necessary, such as a roller 1.
