Abstract: PURPOSE:To easily arrange and preserve sheets of recording paper of only a case in question at the time of receiving a transmission letter as the first page by recording second and following pages on second and following sheets of recording paper in the case where the number of overall recorded pages of received picture information is odd. CONSTITUTION:In the facsimile equipment which records information on both faces of recording paper, the number of overall recorded pages of received picture information is counted, and the recording face of recording paper is determined based on this number. That is, the same recording as conventional is performed when the number of overall recorded pages is even; but when it is odd, the first page is recorded on one face of the first sheet of recording paper, and the other face is made blank, and picture information of second and following pages are recorded on second and following sheets of recording paper. Since the other face of the first sheet of recording paper is blank and is apt to be mistaken for a fault of the equipment, a message is recorded which indicates that the other face is blank because the number of overall recorded pages is odd.

Abstract: PURPOSE:To decrease the capacity of an airtight chamber for cutting down the cost thereof by a method wherein the chamber loaded with a specimen is mounted on a movable stage. CONSTITUTION:The capacity of an airtight chamber 1 mounted on a movable stage 3 shall be acceptable so long as a specimen 6 can be loaded on the chamber 1. The driving mechanism 9 to drive the movable stage 3 need not be installed inside the chamber 1. Accordingly, the air-tight chamber 1 can be miniaturized thereby enabling the capacity thereof to be decreased. Therefore, the manufacturing cost of the chamber 1 as well as the space occupied by the title annealing device can be decreased. Besides, the exhaust time reaching the specified vacuum degree can be shortened. Additionally, the gas consumption for the creation of atmosphere under specified pressure can be cut down. Furthermore, the element to be contained in the airtight chamber 1 excluding the specimen 6 can be minimized while the driving mechanism 9 need not be contained in the chamber 1. Through these procedures, the creation of clean and airtight atmosphere can be facilitated.
