The present invention provides a resin curing apparatus which can cure light-cured resin in a small period of time after emitting a light ray for curing resin, and a small and light optical apparatus which can condense a parallel light ray incident upon an entrance plane in an area narrower than that at the time of incidence upon the entrance plane without attenuating optical intensity. The resin curing apparatus of the present invention includes a plurality of light emitting devices are caused to emit a light ray by a drive electric current larger than a rated electric current while forcibly cooling each light emitting device by a cooling fan, thereby obtaining a large quantity of light with the high optical intensity capable of curing resin in a short period of time.
摘要:
A winding apparatus and a winding method for positioning a leading end of a film layer with high precision. The film is loaded at a position away from a winding position for winding the film around a bobbin and the leading end of the film is brought into contact with the bobbin by using a retainer. At the same time, to control the length of the film to be wound to improve reproducibility of the shape of a transformer a drag chuck is provided, and the drag chuck is controlled through a servo control.
