    Abstract: Commercially attractive continuous processes for the preparation of mesophase pitches for manufacturing high-performance carbon fibers are disclosed. One feature resides in that conversion of a pitch into a mesophase pitch is conducted continuously by using a unique continuous dispersion-heat-treating apparatus. The other feature resides in that the raw material for hydrogenation treatment which is a pretreatment preceeding to the final heat treatment for the production of a mesophase pitch, is prepared by using a heavy oil or pitch having substantially no BTX-insoluble material as the starting raw material, subjecting the raw material to a simple four-step treatment of (1) a continuous heat treatment in a tubular heater, (2) a distillation operation, (3) a BTX-solvent extraction and (4) a distillation operation; while recycling a soluble component obtained in the step (4) to the heat treatment of step (1) and recovering a BTX-solvent insoluble component formed in step (3) as the material for the hydrogenation treatment. This feature can provide a significant increase in the yield of a mesophase pitch. Furthermore, unexpectedly, the recycle of the soluble component into the heat treatment of step (1) is helpful to improve the characteristics of the ultimate products, i.e., carbon fibers or graphite fibers. Combination of the first and the second features, of course, can provide a better commercial success. In fact, the process of the present invention can provide a carbon fiber having a tensile strength of more than 300 kg/mm.sup.2 and a graphite fiber having a tensile strength of more than 400 kg/mm.sup.2 and a modulus of elasticity of no more than 60 ton/mm.sup.2. Processes with minor modifications to the above are also disclosed.

    Abstract: A fixing device for use in a copying machine. The device has a heating roller, a pressure roller, and a separation pawl. The pawl has an end portion contacting the peripheral surface of the heating roller at a first point close to a second point where the pressure roller and the heating roller contact each other. The pawl separates a sheet, on which an image has been fixed, from the heating roller, and guides this sheet along a line tangent to the periphery of the heating roller and connected to the second point. The sheet is thus prevented from being deformed.

    Abstract: A slant plate-type variable displacement compressor includes a housing enclosing a crank chamber, a suction chamber, and a discharge chamber. The housing includes a cylinder block, and cylinder bores are formed therein. Pistons are slidably disposed within the cylinder bores. A valve member is disposed in a first passage, which communicates between a discharge side of the cylinder bore and the crank chamber. The valve member is controlled by a suction pressure of the cylinder bore. A second passage communicates between the crank chamber and a suction side of the cylinder bore through an orifice for allowing pressure to release. A cross-sectional area of the orifice is variably controlled, such that when compressor operation begins, the cross-sectional area of the orifice is greater than that during a capacity control operation.
