    • A motor comprising: a rotor which is supported via a rotating shaft in a radial direction of the rotating shaft, the rotating shaft being disposed around a fixed shaft provided on the side of a stator to form a dynamic-pressure bearing; a stator-side thrust magnet disposed in the stator so as to support the rotor with respect to the stator in a thrust direction of the rotating shaft; a rotor-side thrust magnet disposed in the rotor; and a rotating main body portion mounted to the rotating shaft of the rotor and formed integrally by a resin magnetic material, in which a main magnet portion, an FG magnet portion for generating a speed-of-rotation detecting pulse, and a rotor-side thrust magnet portion serving as said rotor-side thrust magnet are respectively polarized at predetermined positions in the rotating main body portion. As a result, the reliability of an optical deflector in which the motor is used improves and the number of parts and the number of assembling processes are both reduced due to a simple structure. Further, a balance correction operation of the rotor is eliminated so as to allow a simple manufacturing operation, and even when the rotor is rotated at high speed, a stable optical scanning operation can be effected.

    • An apparatus for growing a material at high temperature and employing a reaction gas. A reaction vessel is formed of a metal sidewall having outer and inner surfaces, the inner surface surrounding and defining a reaction chamber within the reaction vessel and which is generally vertically oriented. A cooling system maintains the metal sidewall of the reaction vessel at a temperature at which the metal does not produce contamination within the reaction chamber as a result of the high temperature operation, the reactant gases introduced into the reaction chamber or the product gases resultant from the reaction. A support mechanism includes a generally vertically oriented rod member which supports a susceptor, adapted to hold a wafer on which the material is to be grown, within the bottom part of the reaction chamber and, further, seals the reaction chamber. A sleeve is disposed closely adjacent to but spaced from the inner surface of the generally cylindrical metal sidewall portion and is of a material which remains stable at the high temperature of the reaction required for growing the material.
