IPC: H01L21/203
Filed: 1984-11-19
Abstract: PURPOSE:A vessel for feeding a substance to be vaporized is demountably set over the molecular beam cell and the substance which is dropped into the cell is vaporized again to deposit around the feeding vessel whereby the impurities of the surface of the substance to be vaporized is removed in high efficiency to shorten the time for purification. CONSTITUTION:A chamber 2 for containing a molecular beam cell is set beneath the crystal growth chamber 1 so that they are passable to each other. A crucible 3 equipped with heater 4 is set in the chamber 2 and a conical vessel 5 for feeding the substance to be vaporized is set above the crucible 3 demountably. When the crucible 3 is heated, the substance to be vaporized 8 is melted in the feeder 5 and drips through the small hole 6 into the crucible 3. The falling substance 8 is vaporized again in the crucible 3 with that to adhere to the outer wall surface of the feeder 5. The deposit becomes particle and the diameter of the particles becomes larger and the substances drips again by its self- weight ito the crucible. The repitition gives the high-purity vaporizing substance.

Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To quickly and automatically perform equalization and restrict a final equalization error to a minimum when characteristics of an equalizer to which reproduced digital signals are supplied are to be automatically adjusted. SOLUTION: A CPU 11 generates an equalization parameter for an equalizer 4 (an amplitude equalizer 4a and a phase equalizer 4b), thereby to automatically adjust characteristics of the equalizer 4. The CPU 11, reading a detected count of sinks from a sink detection circuit 8 and a corrected count of C1 errors by an error-correcting code, determines the equalization parameter to make an equalization error minimum according to a 'hill-climbing control method'. An equalization state is divided into three levels according to the control method and a using evaluation value is switched in the levels. In other words, when the equalization state is worst, the detected count of sinks is used. When the equalization state is best, the count of sole C1 errors is used. In the middle equalization state, the count of all C1 errors is used.  The evaluation value shows the highest sensitivity to a change of the equalization error in each level.
