Abstract: The present invention concerns a supporting structure of a single tube drift generator. Supporting brackets (9) are formed by integrating fixed plates (8) extending generally through the overall length of a tube body (2) of a single tube drift generator (1) with support leg members (7) extending in the axial direction of the single tube drift generator (1). The supporting brackets have right and left side frames (9a) and (9b) integrally forming the fixed plates (8) with the support leg members (7) and the cushioning material (9c) provided between the pair of right and left side frames (9a) and (9b). A plurality of support brackets (9) are disposed on the side surface of the tube body (2) of the drift generator (1), and the tube body (2) of the drift generator (1) is connected, through generally the overall length thereof, to the fixed plates (8) of the support brackets (9).

Abstract: A cavitation generating device, wherein the chordal side edges of a pair of semi-elliptic vane panel disposed in a pipe body allowing fluid to be force-fed are crossed aslant with each other, a space between code side edges on the upstream side of the crossed part is closed by a partition plate dividing a pipe body cross-section into two parts, an opening part formed between a chordal edge of one semi-elliptic vane panel on the downstream side of the crossed part and a chordal edge of the other semi-elliptic vane panel on the upstream side of the crossed part is closed partially by restricting means such as a baffle board so as to form a guide vane, and an arc side edge of the semi-elliptic vane panel of the guide vane is connected to the inner wall of a fluid force-feeding pipe body; a fluid mixing device, wherein a plurality of projections are projected radially from the inner peripheral board surface of the pipe body on the downstream side of the guide vane.
