Method of directly manufacturing a product using holographic techniques to geometrize information, and a machine tool according to the same method. A conventional machine tool manufactures a desired product by cutting a mineral material solidified in the prescribed shape with a cutting edge, a laser or the like, and is an external machining method. Accordingly, it is limited by its design from directly manufacturing a complicated or topological product such as something with an internal structure. This invention overcomes this disadvantage. By the application of a holographic technique capable of arbitrarily performing a spatial distribution of electromagnetic or sonic wave as the wave energy, the design information of the product obtained in advance can be obtained as a spatial energy distribution, the design information of the three dimensional product is solidified through the sublimation of gasified material utilizing the difference between the high and the low wave energies in the spatial distribution, e.g., the temperature difference, thereby directly manufacturing the product.
摘要:
A suspension device for suspending a member to be supported above a support, in which a sphere (2) is rotatably retained on the first constituent member (A) disposed on either the support or the member to be supported, and the second constituent member (B) is so supported as to be brought into slidable contact with the recess (3) of the second member IB) disposed in contact with the other side of the member to be supported or the support. A supporting cylinder (1 1 ) is slidably engaged with the outside of the first member (A), and is hinged with the cylinder (11) and the second member (B) by a parallel linkage The cylinder (11) is pulled to one side by a pulling unit, the sphere (2) is brought into pressure contact with the recess (3) of the second member (B), and the member to be supported is stably retained at the predetermined position on the support by utilizing the radial force between the sphere and the recess. This suspension device can be used as the suspension device for the car body of a transport engine or a building structure.
