A magnetic field generating device is situated adjacent to the vacuum chamber for generating a predetermined magnetic field in the vacuum chamber, and a gas introducing system is connected to the vacuum chamber for introducing a reaction gas into the vacuum chamber. Since the base plate holder has a shape corresponding to an external shape of the base plate, a distance between the base plate and the base plate holder is uniform. The films with uniform thicknesses can be formed on both surfaces of the base plate.

摘要： A process for the production of .alpha.-hydroxy acids or .alpha.-hydroxyamides in which an .alpha.-hydroxynitrile compound or a mixture consisting of an aldehyde and prussic acid, which corresponds to the nitrile compound, is allowed to undergo a microbial reaction to produce the corresponding .alpha.-hydroxy acid or .alpha.-hydroxyamide, wherein the improvement resides in that phosphite ions or hypophosphite ions are allowed to be present in the reaction system. According to the present invention, since hydrolysis or hydration of nitrile compounds can be carried out by constantly keeping a low concentration level of aldehydes which are considered to be a cause of the enzyme inhibition in the reaction system, the enzyme activity can be maintained stably for a prolonged period of time and the formed acids or amides can therefore be accumulated in a high concentration.
