Method and device provide for the encapsulation of control information in a real-time data stream. The reflector, which makes the light source produce a desired light pattern without using any shade interposed between the reflector and the lens, has a free curved surface and is designed with a multi-ellipsoid equation. Upon a user request for a specific report, the characteristics of the user are compared with the characteristics stored in the corresponding report object. Upon conclusion of the cycle the articles are removed from the chamber. The post-exposure resist is then easier to control during a subsequent reflow process to reduce the hole size or line size of the patterned resist. Also, a collector who wishes to collect raw garbage from a discharge opening of the raw garbage liquefying apparatus is identified, and collection of the raw garbage from the discharge opening is allowed only in cases where the collector is judged to be appropriate.
