Title: Fixing roller
Inventor: NAGAFUJI HIDEO
IPC: G03G15/20
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of rust on the outer peripheral surface of a fixing roller and to protect the fixing roller from being made unrotatable because of having a bearing shaved by the rust and increasing fixing driving torque by chips by applying sand blasting processing over the entire area of the outer peripheral surface including the paper passing part of core material and the bearing part or the like and successively constituting a primer layer and a fluorinated carbon resin layer on a surface. SOLUTION: The surface having fine unevenness is formed by applying the sand blasting processing over the entire area of the outer peripheral surface including the paper passing part W of the core material 2 and the bearing part 6 or the like. The primer layer 9 and the fluorinated carbon resin layer 11 are successively constituted on an uneven surface. In this case, the surface roughness of the uneven surface is made as Rz8-20μm. Since the releasing property of the layer 11 is usually excellent, the layer 11 is easily stripped in the case of being directly provided on the outer peripheral surface of the core material 2, so that the primer layer 9 is provided on the outer peripheral surface of the core material 2 and the layer 11 is provided on the outer peripheral surface. Thus, stripping is suppressed.

Abstract: PROBLEM TO BE SOLVED: To solve the oil leakage from the breather of an operating oil tank resulting from the return oil from hydraulic equipment by forming a discharge port for discharging the return oil dispersively in the pipe axial direction around the tank internally protruded part of a return pipe. SOLUTION: A plurality of discharge ports 8a are formed on the circumferential surface 8A of the tank internally protruded part of a return pipe 8 protruded into a tank through a tank bottom surface 6C to horizontally straighten the flowing direction of the return oil discharged from the discharge ports 8A of the return pipe 8 within an operating oil tank T.

Abstract: PROBLEM TO BE SOLVED: To enable a nut to bear up against vibration and shock for making its reutilization possible by facilitating the expansion and contraction or shortening in diameter of the upper part of a nut body, and providing a plurality of slits at the upper end or in a lower part of the nut, and in the case of attaching the nut to a bolt, sliding an armor body from an upside toward a downside to tightly press the nut body. SOLUTION: A nut main body 1 is inserted from the end of a bolt X in a state that the upper end side of the slit 5 of a nut body 2 is expansively opened centering around the connecting part 3a of a prismatic pedestal 3. Next an armor body 11 is inserted and armored on the nut body 2 and slid downward along the oblique periphery of the nut body 2, and when the pedestal 3 is screwed in the bolt X, torque acts downward in the axial direction of the bolt X. When the nonsliding face 23 of the armor body 11 is further pressed in along the nonsliding face 22 of the nut body 2 to tightly fit the armor body 11 in the nut body 2, the nonsliding faces 22, 23 overlap mutually to tightly press the nut main body 1 to the bolt X, and torque in the reverse radial direction toward the axis of the bolt X therefore acts. Thus rotation and reverse sliding are impossible and the nut does never loosen.
