Abstract:
Disclosed herein is a heating apparatus designed to heat an object to be heated through induction heat generation of a heat generating part made of glasslike carbon, and that can rapidly raise or lower the temperature without contamination of the object which has a large area and is formed into a shape of a substrate such as a silicon wafer. The heating apparatus includes a heating container for receiving the object. The container is constructed such that at least a portion of the container formed into a shape of a plate is made of glasslike carbon, and that the portion of the container serves as a heat generating part. A high-frequency plate-shaped coil is disposed at the outside of the container while the coil is adjacent and is opposed to the heat generating part of the container, and which is wound approximately into a shape of a plate. The heating apparatus further includes a container-inside gas atmosphere control means for controlling the inside of the container to be maintained at a predetermined gas atmosphere. When electric current is supplied to the coil, heat is generated from the heat generating part through induction heat generation of the heat generating part, whereby the object is heated.
Abstract:
A two-phase glass-like carbon member has, in combination, a porous glass-like carbon base, and a dense glass-like carbon surface layer formed on the porous glass-like carbon base. The porous glass-like carbon base can be formed in a large thickness. The dense glass-like carbon surface layer is superior to the porous glass-like carbon base in gas impermeability, surface hardness and resistance to dusting. The dense glass-like carbon surface layer supplements disadvantages of the porous glass-like carbon base. The two-phase glass-like carbon member can be in a large thickness exceeding 5 mm and in a complicated shape.
Abstract:
Provided is a process for producing a glass-like carbon deformed molded article having a deformed section (typically, an elliptical section or a section composed of partial circles and linear portions), such as a glass-like carbon member in a deformed pipe form or a bent pipe, with relative ease and a good dimensional accuracy. The process comprises the step of molding a thermosetting resin to yield a thermosetting resin molded article, the step of deforming the thermosetting resin molded article plastically in the state that the article is heated, so as to yield a thermosetting resin deformed article, and the step of carbonizing the resultant thermosetting resin deformed article.
