In the formation of a conductive rollera compound forming an elastomer by curing through an electron beam irradiation or a ultraviolet ray irradiation is applied onto an outside of a shaft memberto form an elastomeric coating layerR and then the elastomeric coating layer is cured through an irradiation of an electron beam or a ultraviolet ray to form an elastic layer, whereby the elastic layer can be formed cheaply without sacrificing precision of peripheral dimension to largely reduce the cost of the conductive roller.

Method of producing a conductive roller utilizing a semi-curing step

A conductive roller such as a developing roller, a charging roller or the like provided with a resin coating layer on a surface of an elastic layer, and more particularly to a conductive roller having the resin coating layer using an ultraviolet-curing type resin or an electron beam curing type resin and being obtained by contriving a structure of the resin coating layer, rendering the resin coating layer to contain microparticles, controlling the particle size of the microparticles, or forming the resin coating layer after the outer peripheral surface of the elastic layer is subjected to surface treatment.

There is provided a blind operating device for transmitting a rotation in both directions from an operation portion to a driving axis of the blind capable of making a diameter of a clutch spring smaller, and then capable of reducing operation load without breaking the clutch spring. The blind operating device includes an input shaft into which a rotation from a pulley is inputted, and a rotation axis that is provided coaxially with the input axis and is capable of transmitting the rotation to the driving axis. A clutch spring is wound around a fixed spring winding axis of a case and a rotation spring winding axis of the rotation axis. Linking and de-linking of the rotation axis and the case is made possible utilizing tightening and loosening of the clutch spring and one end of the clutch spring is linked to the rotation axis. When the rotation in one direction is inputted to the input axis, a part of the clutch spring wound around the fixed spring winding axis loosens starting from a rotation spring winding axis side, whereby the rotation axis is allowed to rotate with the input axis.

To provide an on-failure blind stopper system that allows reduction of depth of a head box and can be surely activated. A slider capable of moving vertically is disposed in a head box. The slider is pressed by a lifting/lowering cord and prevented from moving upward to permit a rotation shaft to rotate when the lifting/lowering cord is under tension. On the other hand, the slider moves upward to engage with the rotation shaft to prevent the rotation of the rotation shaft when the lifting/lowering cord sags.

A blind which allows the space underneath either desired end of its head rail to be opened by folding louvers beginning with the one at the desired end by a simple operation. A louver is hung from each one of a plurality of carriers that can move within a head rail and, among the carriers, the carrier arranged closest to the first end a of the head rail constitutes a first master carrier, and the carrier arranged closest to the second end of the head rail constitutes a second master carrier. By manipulating a first operating device, the first master carrier is moved toward the second end of the head rail to open the space underneath the first end, and by manipulating a second operating device, the second master carrier moved toward the first end of the head rail to open the space underneath the second end.

An LCD module covered a protective film and stored in a vinyl bag is held by cushioning material, and the cushioning material is placed in a box. A plurality of grooves are formed in a mutually parallel fashion on the lower and upper members of the cushioning material. The grooves form a supporting portion for supporting the edges of LCD modules that are fitted in the grooves. The depth of the grooves is slightly less than the width of the frame area of the LCD modules. An upwardly protruding convexity is formed in the area between the grooves and on both sides of the rows comprising the plurality of grooves. The convexity is a pop-out prevention portion for preventing LCD modules from popping out from the cushioning material during transport. Soiling can thereby be prevented from occurring on the display area of the display modules.
