A substrate containing at least metallic aluminum is subjected to a heating treatment in vacuum of 10−3 torr or less, and subsequently it is subjected to a heating/nitriding treatment in a atmosphere containing at least nitrogen to form a nitride film. A porous body through which a nitrogen atoms containing gas flow is clarified by heating at a temperature of 1000° C. or more under pressure of 10−4 torr or less, and then the porous body is contacted the atmosphere during the heating/nitriding step.

Abstract: A facsimile machine (F) that is capable of performing a confidential transmission, broadcast transmission, etc. by batch transmission. If a user of the facsimile machine wants to send a plurality of image data to a recipient, for instance, confidentially and simultaneously at a specified time, the image data is accumulated in a memory box (5a) for confidential batch transmission. The image data is then sent to the recipient by batch transmission. The facsimile machine (F) determines whether image data is for batch transmission or real time transmission. If the image data is for real time transmission, it is not stored in the memory box (5a).

Abstract: The present invention relates to a facsimile device that is connectable to a plurality of lines. When a facsimile transmission is made, information regarding the transmission source (the facsimile number, the sender's name and the like) is normally transmitted as TSI signals or as a part of the image data (TTI) to the receiver side. According to the present invention,TTI information (line information) can be set for each of a plurality of lines and a particular item of the line information can be selected as desired. Thus, the same line information (TTI information) can be transmitted over all the lines when a simultaneous broadcasting transmission is made using a plurality of lines. In addition, when some lines are used exclusively for transmission and some are used exclusively for reception, any confusion of the TTI on the receiver side will be avoided because misuse of the sender's dedicated transmission lines for reception of a return fax from the original receiving side can be reliably avoided.
