Abstract:
PROBLEM TO BE SOLVED: To provide a method of molding which can mold a molded article with high precision, a method of manufacturing a molded article, and a molding apparatus. SOLUTION: The molded article such as a lens array, a mold for nano imprints or the like is molded by the method of molding. The method of molding comprises: repeating plural times of a transfer process including: a transformation step of making a photohardening resin and transfer bodies (62) provided with transfer configuration areas consisting of the same configuration with a lens part (312) or the opposite configuration with the lens part (312) contact together to thereby transform the photohardening resin in conformity with the transfer configurations of the transfer bodies (62); a hardening step of hardening at least the transformed areas of the transformed photohardening resin; and a departing step of making the hardened photohardening resin and the transfer members depart from each other; and uniting with the contraction of the photohardening resin and changing the pitch of a position where the transfer bodies (62) contact the photohardening resin or the configuration of the transfer bodies (62).

PROBLEM TO BE SOLVED: To provide a molding object manufacturing method which can produce a molding object accurately in a short time, a stamper manufacturing method related to the molding object manufacturing method, a master manufacturing apparatus, a stamper manufacturing system, and a stamper manufacturing apparatus. SOLUTION: The master 600 having a first offset surface 602 composed of the same shape as a first optical function surface 652 of a lens array 650 etc., is produced, a first stamper 620 having a first reverse shape surface 622 composed of a reverse shape to the first offset surface 602 etc., are produced, and the lens array 650 is produced by using the first stamper 620 etc. The master 600 is produced by repeating the transfer process in which a master material and a transfer body are contacted with each other to deform the master material, the deformed part of the master material is cured, and the master material and the transfer body are separated from each other at least two times so that the transfer body is contacted with positions different from each other of the master material.

PROBLEM TO BE SOLVED: To provide a shaping method which enables high precision-shaping of a shaped product such as lens, compared with conventional technique, and, a shaping device and a lens manufacturing method which enables molding of a high precision lens far beyond a conventional lens. SOLUTION: This shaping method uses a transfer process comprising (1) a distorting step which brings a photo-setting resin into contact with a transfer member 62 with a transfer forming part of the same form as a lens part 312 of a nonspherical configuration or of a counterform to the lens part 312 of a nonspherical configuration and distorts the photo-setting resin to the transfer form of the transfer member 62, (2) a curing step which cures at least, the distorted part of the distorted photo-setting resin by irradiating with a light by a light irradiation device 60, and (3) a separation step which draws apart the cured photo-setting resin from the transfer member. Further, a shaped product such as an lens array or a mold for nanoimprinting, is created by repeating this transfer process a plurality of times. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a holding device capable of more excellently holding an object to be held such as micro machine parts, for instance. SOLUTION: This holding device 10 has two finger members 46, elastic beams 38 for energizing the finger members 46 in a mutually approaching direction, and a micrometer head 22 provided with a spindle 36 for mutually separating the finger members 46 against the energizing of the elastic beams 38. When pressing surfaces 50 of the elastic beams 38 are pressed by moving of the spindle 36 of the micrometer head 22, the elastic beams 38 are elastically deformed, and distal end parts 56 of the finger members 46 are mutually separated.
