    摘要： A method for forming an optical element having a microstructure includes the steps of: providing a mold (30) having a pattern; disposing an optical perform (40) adjacent the mold with a portion thereof facing toward the predetermined pattern of the mold; heating the optical preform up to a predetermined temperature; hydrostatically pressing the mold onto the optical preform such that a to-be-processed portion of the optical preform is formed into the predetermined microstructure; and removing the mold from the treated optical preform to obtain the optical element. A hydrostatic pressing apparatus (55) is utilized to provide a uniform pressure applied to the mold. This ensures that the formed microstructure of optical elements having a high precision. In addition, the infrared quartz heaters are capable of instantly elevating the temperature of the optical preform. Thus, the whole process may be finished in a relatively short time.

    摘要： A powder pressing apparatus comprises an upper punch and a lower punch for compression of a powder in a cavity formed in a through hole of a die. A gap between a side surface of the lower punch and a side surface of the through hole of the die is sealed by a sealing member. A lubricant is supplied with a gas from a nozzle in the side surface of the lower punch to the side surface of the through hole, and the lubricant applied to the side surface of the through hole is spread by an absorbing member. The cavity is filled with the powder while the cavity is under suction by a reduced pressure provided from the nozzle in the side surface of the lower punch. During the suction, a filtering member provides filtration for the lower punch not to draw the powder in.

    摘要： Apparatus and method for superplastic forming. The workpiece is held between a pair of dies that are electrically and thermally nonconductive, and is heated inductively by a coil embedded within the dies. The dies are formed of a material that is substantially transparent to inductive heating. A plurality of electrical conductors are embedded within the die. The electrical conductors are interconnected into one or more electrically conductive coils that surround the workpiece. The electrical conductors are used to produce a time varying magnetic field that is used to heat the workpiece. In one embodiment, the workpiece is a composite material that is susceptible to inductive heating. The composite material includes an electrically conductive material. The time varying magnetic field heats the electrical conductive material, thereby heating the workpiece. The die also includes a forming surface having a shape corresponding to a desired shape of the workpiece. A pressure differential is created between the first and second sides of the workpiece to deform the workpiece to the shape of the forming surface.

    摘要： An imprint device and an imprint method which form mold patterns on both surfaces of a molding target. An imprint device transfers mold patterns on both surfaces of a molding target using flexible first and second dies and includes first and second casings which each apply pressure of first and second pressurizing rooms respectively, to the first and second dies respectively and the molding target, a pressurizer that adjusts the pressures of the pressurizing rooms, first and second moving units that move the first and second dies respectively and the molding target in a direction coming close to or distant from each other, a depressurizer that depressurizes a depressurizing room formed between the first and second casings, and eliminates fluids present between the dies and the molding target, and a pressure adjuster that adjusts pressures to reduce pressure differences between the depressurizing room and the pressurizing rooms.
