Abstract: PURPOSE:To improve cutting accuracy and work efficiency by providing the end of a main spindle with two or more rack-and pinion-orthogonal transformation mechanisms and, performing multiple contact point cutting by cutting tools mounted on a plural number of corresponding relative tool attachments on the output side. CONSTITUTION:A milling spindle 2 and a face plate unit 3 are advanced at a given feed speed, with both of them being in simultaneous rotations, so as to allow two point contact cutting by the pair of cutting tools 7A, 7B. Due to this machining, a diameter deflection is not produced on the face plate 3, even of cutting resistance comprising the resultant force of a back force, a main force, a feed force, etc., is applied to the cutting tools 7A, 7B during cutting. Further, a main spindle 1 is allowed to advance to have cutting tool attachments 6A, 6B and the cutting tools 7A, 7B projected beyond the diametral direction of the main spindle 1 through the intermediary of a pair of rack-and pinion-orthogonal transformation mechanisms 5A, 5B. This constitution allows long secrce life of the cutting tools and improves cutting work efficiency.

Abstract: PURPOSE:To expand the width for selection of materials and to increase the degree of designing freedom for an FET by a method wherein a buffer layer and a cap layer are formed of superlattice semiconductors formed by alternately laminating at least two or more kinds of II-VI compound thin films composed of group IIB elements and group VIA elements. CONSTITUTION:In a field-effect transistor FET, III-V compound semiconductors are used for a channel layer 13; a buffer layer 12 and a cap layer 14 are formed of superlattice semiconductors formed by alternately laminating at least two or more kinds of II-VI compound thin films composed of group IIB elements and group VIA elements. Namely, when a growth method is contrived so as to completely separate a growth chamber for II-VI compound semiconductors from that for III-V compound semiconductors, the problem of contamination is solved. Also the compound semiconductors have the following advantages: they have generally a strong self-compensation effect; they make it possible to easily obtain a high resistance; and they can be used very easily as materials for the buffer layer. Thereby, the width for selection of materials is expanded, the degree of designing freedom for the FET can be increased, and the FET having a good characteristic can be obtained easily.
