Abstract: PROBLEM TO BE SOLVED: To install a denitrification bioreactor at an optional place (at any place except an anaerobic tank) and to repeatedly use the bioreactor as a single body so that it is a cartridge type. SOLUTION: A biological membrane generated on a hydrogen donor transmission membrane 11 surface is maintained under anaerobic environment inside the membrane body by having a membrane body structure formed by laminating layer 12 for shielding dissolved oxygen on the hydrogen donor transmission membrane 11 surface, so that activity of a denitrification reaction is reinforced. The denitrification bioreactor X enables to form a sealed section enclosing a hydrogen donor (methanol) 2, in nitrate nitrogen-containing water, and consists of a cartridge type membrane body container 1 repeatedly usable as a single body, and at least one sectional wall is formed of the hydrogen donor transmission membrane (a polyethylene membrane) 11 and nonwoven fabric 121 is laminated or covered on the membrane surface, so that the denitrification bioreactor has a membrane body structure on which a layer (an air shielding membrane) for shielding dissolved oxygen is formed by lamination.

Abstract: PURPOSE:To obtain an aluminum-dispersed Al-Ti intermetallic compound composite as a lightweight heat resistant material in which alpha-Al2O3 is uniformly dispersed in a matrix of Al-Ti intermetallic compound by subjecting TiO2 (rutile) and Al (Al alloy) to reaction and hardening by means of compounding and structure regulation. CONSTITUTION:TiO2 (rutile), prepared by powder regulation or by forming the resulting powder into a preform, and Al or Al alloy are compounded by means of pressure casting. At this time, the hardness-controlled hard material can be supplied in a short time by changing treatment temp. and forming this material by means of nonreactive compounding and successive reactive hardening by heat treatment or forming it by means of compounding and reactive hardening. Further, when compounding is done, gradation is provided at the time of arranging TiO2 (rutile) in a mold and hardening reaction is localized, by which an arbitrary part can be hardened. The ratio of TiO2 (rutile) to Al (Al alloy) by volume is regulated to 3-70%. This material is useful as a composite material containing Al-Ti intermetallic compound as matrix.

CONSTITUTION:A model 21 is set on a working table 20, and a mold release agent is applied thereon so that a desired thickness heating layer is formed on the model 21 by m of a flame coating device 22. Next, in order to form a fluid conduit for die temperature control, for example, copper pipes 24 are arranged appropriately and a thermosetting resin or the like is flown therein and cured so as to form a back-up member 25. In this instance, the whole of a die apparatus can be reinforced in use of the frame 26 of a steel or the like. After curing the back-up material, the model 21 is removed and the die surface is finished as required. Moreover, for making a protective coat 10, an alumina flame coating is at first performed on the die surface of the model 21 prior to a flame coating process to be a protective coat 10, after that, copper-sericite powder is flame-coated thereon in order to form a heating layer 11.
