  • Method for generating hard, wear-proof surface layers on a metallic material
    Patent number: 4537793
    Abstract: Hard, wear-proof surfaces are produced on a metallic material, such as a ferrous material, by applying a decomposable compound containing an element capable of hardening metallic materials, in the form of a powder, a paste-like admixture or a liquid, onto surfaces to be hardened, and applying an energy surge, obtained from, for example, a laser beam or an electron beam, to the surfaces containing such coating so as to decompose the coating and release the element which diffuses into the surface to be hardened. With this process, the base material is not subjected to any meaningful thermal loads and is not altered in term of its mechanical and physical properties.

  • Electron beam irradiating process for rendering rough or topographically irregular surface substrates smooth; and coated substrates produced thereby
    Patent number: 4537811
    Abstract: This disclosure involves a novel process for instantaneous electron-beam curing of very thin low viscosity, solventless coatings upon rough, irregular or textured surfaces of a substrate, such as paper or the like, that, through rather critical timing and energy adjustment procedures, causes the coating firmly to adhere to the surface before the coating can conform to the roughness or texture contour, and thereby providing a solidified very smooth outer surface for the substrate that is particularly useful for metalization and other finished layerings.

  • Heating method of semiconductor wafer
    Patent number: 4525380
    Abstract: A method for heating a semiconductor wafer which may have a first region to be heated and a second region requiring no heating thereof, which method comprises forming a film on a surface of the semiconductor wafer so as to make the reflectivity of the whole surface of the wafer uniform, and then exposing the semiconductor wafer to a flash of light to heat same. The above method permits to heat the whole surface of the wafer at a uniform temperature thereby heating a region of the wafer which is required to be heated, and, at the same time, avoiding any overheating of another region of the wafer where no heating is required. The above heating method is effective for annealing a semiconductor wafer which has large surface area.
