A gun suitable for games is disclosed for permitting an operator to recognize when a trigger is pulled. The lubricant adjusting member is separated from the inner circumferential surface of the belt member, at least while the recording medium and the belt member are in contact with each other and while rotation of the belt member is stopped. A second set of QPs can then be defined for a second coding pass. Predefined sets of templates may be used to check the messages, each set of templates being associated with respective originating point codes andor calling party addresses. The epitaxially grown semiconductor region is then used for enhancing one type of transistor while the semiconductor layer of the second surface orientation is used for enhancing a different type of transistor.
