摘要： A process for forming a tubular member is provided which includes a pre-forming process for tube-expanding (bulge) forming and bending forming a tubular material using first and second molds and a final forming process for crush forming a preformed tube using a third mold so as to give its cross section a desired shape, the pre-forming step being carried out using the first and second molds heated at temperatures equal to or higher than the recrystallization temperature of the tubular material and the final forming step being carried out using the third mold heated at temperatures equal to or lower than the recrystallization temperature of the tubular material. The process enables a tubular material of aluminum alloy to be formed into a tubular member of high precision and high quality which has expanded portions as well as bent portions and whose cross section varies across its length.

摘要： A shape data specifies the shape of an elongated product within an overall coordinate system. Local coordinate systems are defined on respective cross-sections of the elongated product in the overall coordinate system. The local coordinate system is designed to represent a stable die of a bending apparatus. The images of the elongated product protruding forward from the stable die within the respective local coordinate systems serve to specify the position of a movable die of the bending apparatus. The specified position reflects the deformation induced in the elongated product between the stable and movable dies. An ideal movement amount of the movable die can be determined based on the determined positions within the local coordinate systems. The determined movement amount can be utilized to prepare the control data for the bending apparatus. When the prepared control data is supplied to the bending apparatus, an ideal movement of the movable die can be achieved so as to effect bending on the elongated workpiece at a higher accuracy in accordance with the shape data.

摘要： There is disclosed a large-sized transmission-type screen used for a multi-image system. If the screen expands or contracts due to variations of the ambient temperature or humidity, generation of creases or relieves is prevented. The transmission-type screen includes image sources for projecting and magnifying optical images, screen members for transmitting the projected optical images, first light-blocking members mounted to edges of the screen members, and a support member having tensioning mechanisms. Each tensioning mechanism applies a tension to the first light-blocking members to hold the components of the screen members in intimate contact with the support member. Each screen member includes a lenticular lens sheet, a composite Fresnel sheet consisting of sheet members bonded vertically, and plural transparent reinforcing sheets. Each reinforcing sheet is substantially identical in size with each sheet member of the composite Fresnel sheet. A second light-blocking member is bonded between the two adjacent transparent reinforcing sheets to prevent the optical images from the adjacent image sources from overlapping.
