摘要： PROBLEM TO BE SOLVED: To provide an intermediate transfer member simple in structure and capable of simplifying its manufacturing process while making good use of characteristic possessed by a rubber belt as the intermediate transfer member, and to provide its manufacturing method and an intermediate transfer device. SOLUTION: This intermediate transfer member is an endless belt type member disposed between an image forming body and a recording medium, driven to circulate by a driving member, temporarily transferring and holding a toner image formed on the surface of the image forming body on its own surface and transferring it to a recording medium. Elastic material is used as a base material layer 1, and a reinforcing member 2 is consecutively embedded in the rotating direction at a part out of an image forming area at both ends or one end of the layer 1.

摘要： PURPOSE: To efficiently manufacture calking rings at low cost by blanking a metal sheet circularly to produce a disk, forming a dish consisting of a bottom and a circumferential part, punching the bottom and retaining the circumferential part as a ring. CONSTITUTION: A hoop material is blanked circularly to produce a disk 11, and a dish is formed consisting of a bottom 12 and a circumferential part 13 from the disk by a press, forming an intermediate product 10; then, the bottom 12 of this intermediate formed product 10 is punched out to produce a ring 1. In this process, a projecting line 14 is provided on the bottom circumference of the upper middle die 23; a stepped part 14 with a thin thickness is formed on the circumference of the bottom 12 of the intermediate formed product 10; and the inside corner of this product 10 is thereby bent nearly at right angle. These processes are all performed by a press, which therefore saves required time, manpower and the manufacturing cost.

摘要： PURPOSE:To grasp many commodities arranged at narrow spaces with small number of expansion tools at one action by supplying a fluid in the closed space of the expansion tools through a passage so as to expand an elastic body, whereby parts, etc., are grasped by a space between the expanded elastic body and a frame. CONSTITUTION:An expansion tool 1 is constructed in such a way that both end portions 2A, 2B of a cylindrical elastic body 2 are respectively fixed to both end parts of a hard base 3 by caulking, a closed space 4 is partitioned inside the elastic body 2, and a passage 5 for supplying and discharging a fluid is formed on the hard base 3 in the closed space 4. On the other hand, frames 6 are disposed at a designated interval in such a manner as to surround the expansion tool 1 to form a grasping device. A fluid is supplied into the closed space 4 through the passage 5 to expand the elastic body 2, so that the parts 7 such as bolts or the like can be grasped between the expanded elastic body 2 and the frames 6. Thus, many parts 7 arranged at narrow intervals can be grasped with small number of expansion tools at one action.
