摘要： A clock signal regenerating circuit includes a first PLL circuit, a PLL part circuit which forms a second PLL circuit in cooperation with the first PLL circuit, the second PLL circuit performing a frequency-synchronizing operation on a clock signal and a data signal. The first PLL circuit performs a phase-synchronizing operation on the clock signal and an output signal of the PLL part circuit. The phase-synchronizing operation has a speed lower than that of the frequency-synchronizing operation.

摘要： 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.
