A screw expander system has a condenser positioned for receiving a mixture of oil and operating medium from a screw expander. The image apparatus determines a type of original format of inputted image data and determines a degree of noise reduction in accordance with the determined type of original format. The outer frame is cut after a resin sealing process is completed. The method also includes moving a suture through a passage in the first section, wrapping the suture around the central post, and moving the suture through a channel of the second section. For example, hydrocarbon resin and tung oil are optionally combined into a naphtha solvent.
