摘要： This invention relates to processes and systems of rapid prototyping and production. Its features includes flexible material deposition along tangential directions of surfaces of a part to be made, thereby eliminating stair-shape surface due to uniform horizontal layer deposition, increasing width of material deposition to increase build up rate, applying the principles of traditional forming/joining processes, such as casting, fusion welding, plastic extrusion and injection molding in the fabrication process so that various industrial materials can be processed, applying comparatively low cost heating sources, such as induction heating and arc-heating. Additional features include varying width and size of material deposition in accordance with geometry to be formed and applying a differential molding means for improved shape formation and surface finishing.

摘要： Provided is a method and apparatus for building a structure of glass using additive manufacturing technology. The apparatus incorporates a method of depositing molten glass material in discrete droplets rather than as a continuous fused filament. The additive manufacturing of glass material relies on the surface tension, the high viscosity of the molten glass, and droplet formation to control deposition by melting the glass filament directly without the use of a needle or crucible.

摘要： In manufacturing method for a thermal head, concave portions, including a reference concave portion, are formed on a surface of a substrate so that a length of each of the concave portions other than the reference concave portion increases as a distance from the reference concave portion in a length direction increases and so that a width of each of the concave portions other than the reference concave portion increases as a distance from the reference concave portion in a width direction increases. A mark identifying the reference concave portion is formed on the surface of the substrate. An insulating film is thermally fusion bonded to the surface of the substrate including the concave portions formed thereon. Heating resistors are formed on the insulating film using a photo mask by aligning the photo mask with the substrate in accordance with the reference concave portion to form the heating resistors so as to be opposed to the plurality of concave portions.

摘要： A titania-doped quartz glass suited as an EUV lithographic member is prepared by feeding a silicon-providing reactant gas and a titanium-providing reactant gas through a burner along with hydrogen and oxygen, subjecting the reactant gases to oxidation or flame hydrolysis to form synthetic silica-titania fine particles, depositing the particles on a rotating target, and concurrently melting and vitrifying the deposited particles to grow an ingot of titania-doped quartz glass. The target is retracted such that the growth front of the ingot may be spaced a distance of at least 250 mm from the burner tip.
