  • Patent number: 6837086
    Abstract: While a workpiece is heated and pressed by one of a pair of high-pressure vessels, a workpiece being pressed by the other high-pressure vessel is placed in a heated state. In the reducing process after termination of heating and pressing treatment of the workpiece by one high-pressure vessel, both the high-pressure vessels are placed in communication, and the pressure medium gas released from one high-pressure vessel is poured into the other high-pressure vessel. After pressures of both the high-pressure vessels have assumed a nearly balanced state, the pressure medium gas is sucked out of one high-pressure vessel by a compressor and pressed, and is poured into the other high-pressure vessel, and the workpiece is heated and pressed by the other high-pressure vessel. By the method as described, considerable shortening of cycle time of HIP treatment is achieved, and the HIP treatment can be carried out with high efficiency.

  • Patent number: 5955738
    Abstract: An exposure data preparing apparatus includes a field placement editor for placing exposure patterns that correspond to design data. Placement is done for each sub-field obtained by dividing a field on an LSI to be designed, and each sub-field has a size that can be covered by deflection of a beam from an exposure apparatus. A map preparing editor prepares a plurality of maps that can be covered by a single shot of the charged particle beam, by dividing the sub-field in which the exposure pattern is placed. A CPU determines a beam dosage of the charged particle beam derived from a density of the exposure pattern in the map.

  • Patent number: 5147086
    Abstract: A process for preparation of capsule for use in isostatic pressing treatment, the process comprising a first step of enclosing a material to be treated, such as ceramic, metal, resin, etc. with metallic foil having a thickness of from 30 to 300 .mu.m, and a second step of welding the metallic foil so as to seal the material to be treated in the metallic foil thus welded, thereby preparing a capsule, wherein the welding is carried out by means of TIG welding. Alternatively, the welding may be carried out by means of seam resistance welding. It is posible, by the process, to seal the material to be treated in a capsule easily and economically. The capsule thus obtained is in a good sealed condition, permits effective isostatic pressing treatment, and enables the treated material to be taken out easily. A ceramic or metal layer covers the material to be treated to prevent adhesion between the material and the metallic foil.
