    Abstract: PURPOSE:To improve working efficiency by arranging correctly a base body of a nut at a predetermined position on the inside of a cavity of a mold, by a method wherein the base body of the nut is supported with a pin by providing the pin in a standing state by a predetermined height from the surface of the mold, and synthetic resin is cast under that state. CONSTITUTION:A cavity (c) demarcating the whole surface of a nut is formed with molds (a), (b). Then a hole (f) in which a core (e) where a male screw (d) is formed is fitted is bored into the surface of the mold (a), and the core (e) is buried into the hole (f). A stopper pin (g) is provided on the surface of the mold (a) in a standing state, and a projecting length of the pin (g) is decided to be a length of a base body (k) of the nut which is to be stayed within a predetermined position of a space of the cavity (c). The mold (b) is constituted so as to be combined with the mold (a). Then the circumference of the base body (k) of the nut is covered with synthetic resin (h) by casting the synthetic resin within the cavity (c). Then the mold (b) is removed, a molded nut N is pulled out of the mold (a) while the core (e) is kept screwed on, and at a point of time when the pin (g) has gotten out of the inside of the synthetic resin (h) completely, the nut N is screwed off from the male screw (d) of the core (e).

    Abstract: PURPOSE:To provide a pressure vessel made from resin with a sufficient airtightness and liquid-tightness by forming on its mouth piece an inclined face directed inwards in the radial direction so that the boundary surfaces of both the pressure vessel and the mouth piece come into close an d time contact with each other. CONSTITUTION:A pressure vessel 19 made from resin is equipped with mouth pieces 31, 32 which are buried and fixed into the position when it is manufactured. The one mouth piece 31 is provided with a large diameter section 31a and a small diameter section 31b, and also at the boundary position between said both sections 31a, 31b, there is an annular inclined face 31c which directs inwards in the radial direction of the mouth piece 31 and also directs towards the outside of the vessel 19. In addition, the other mouth piece 32 is also provided with annular inclined faces 32c, which direct inwards in the radial direction of the closure 32, on the outward side face in the direction of the axis of respective large diameter sections.

    Abstract: PROBLEM TO BE SOLVED: To provide a developing roller which prevents the occurrence of image defects such as spots and density unevenness, and further, fog of a white image, is adaptable even to color images, and can reliably give high quality images, and to provide an image forming apparatus with the developing roller. SOLUTION: The developing roller 1 has a shaft member 2 comprising a hollow or solid cylinder made of a resin containing a conductive agent and one or more resin layers 4 disposed on the radial outside of the shaft member. When a roller periphery is charged by causing corona discharge by applying a voltage of 8 kV to a corona discharger disposed at an interval of 1 mm from the roller periphery, a maximum value of surface potential after the lapse of 0.35 s is ≤90 V.
