Abstract: PURPOSE:To form a braided product having a complicated structure and improve the strength of its joint part, bent part, etc., by suitably passing from a robot hand device to the other for holding a mandrel. CONSTITUTION:Robot hand devices R having mandrel-holding devices S at their tips, respectively, are laterally disposed through the main body of a braider, and a braiding operation is started from one end of, e.g. a T type mandrel (m) held and subjected to a posture control with the mandrel-holding device S of one of the robot hand devices R. After the braiding operation is performed to the branched part of the mandrel (m), the operation of the robot hand device R is controlled to clockwise rotate the mandrel at 90 deg. on the joint point of the branched part, and the braiding operation is performed to the branched part. The other end of the mandrel (m) is subsequently held with the other robot hand device R, and the holding of one robot hand device R is released. The mandrel (m) is rotated at 180 deg. on the branched part, and the braiding operation is performed at the branched part. In such the way, both the robot hand devices R are suitably exchanged for each other to hold the mandrel (m), and the braiding operations are performed, thus forming a braided product having a complicated two-dimensional or three-dimensional structure.

Title: Formation of developer layer
Inventor: FUMA HIROSHI
IPC: G03G15/09
Filed: 1986-02-18
Abstract: PURPOSE:To obtain a developer layer having a desired thickness by pressing an elastic plate to a developer carrying body surface and slipping the developer through the space corresponding to the thickness equal to the grain size of the magnetic carrier of the developer between the elastic plate and the developer carrying body surface. CONSTITUTION:A nonmagnetic cylinder is used for the developer carrying body 103 and the elastic plate 105 having a flat surface is pressed to the carrying body 103 surface. The developer D held by the magnetic field generated by the magnet of the carrying body 103 is slipped out of the space between the carrying body 103 and the elastic plate 105 and is carried to a developing region when the carrying body 103 is moved in a prescribed direction. The relation between the space between the elastic plate 105 and the carrying body 103 and the linear pressure is constant over a wide range at the time of the space corresponding to the grains size of the carrier and therefore, the conveying rate of the developer can be so controlled as to allow the passage of every one piece of the carriers in the contact position of a sleeve 3 by setting the linear pressure between the elastic plate and the carrying body within said range. The formation of the extremely thin developer layer is thus made possible, by which the developing space can be made small and since the electric field is sufficiently large, the image quality such as resolving power and gradation reproducibility of the image to be developed is remarkably improved.
