Abstract: A rotatable target for sputtering is described. This target can include a target backing tube having an exterior surface; a backing layer in contact with the exterior surface of the target backing tube, the backing layer being electrically conductive and thermally non-conductive; and a plurality of target cylinders located around the target backing tube and in contact with the backing layer.

Abstract: A device and method for stacking and packaging cylindrical products having variable size. Products are placed on edge and organized to a uniform stack size by means of a product compressing drum. The stack is placed in a trough between a cam operating front lug and a back lug. Once between lugs, the uniformly sized stack maybe packaged into uniform size packages.

Abstract: A back bag such as a back pack, knapsack or a tucksack has a bottom-equipped bag portion, a pair of shoulder straps provided on the body-contact side of the bag portion and adapted to be hung from the user's shoulders, and a hip belt extending from a lower portion of the body-contact side of the bag portion to surround the user's hip bone. The hip belt is made of a left belt and a right belt connected by fastener, so that the hip belt is adjustable in its entire length or its angle of extension.

Abstract: A back bag such as a back pack, knapsack or a rucksack has a bottom-equipped bag portion, a pair of shoulder straps provided on the body-contact side of the bag portion and adapted to be hung from the user's shoulders, and a substantially V-shaped frame provided on the body-contact side of the bag portion. The frame has both wing portions extending from the lower end apex of the V-form located in a region near the lower end of the backbone of the user's body. The wings being elastically deformable independently of each other with respect to the lower end apex of the V-form of the frame. The weight load is distributed over the area of the user's back, as well as to the shoulders. The frame is plastically deformable in conformity with the geometry of the user's back, so that the bag portion is held in close contact with the user's back without jumping or slipping sideways during a long-distance walk or climbing.
