Title: Moving material guide device
Inventor: ISHIDA MASARU
IPC: B65G47/46
Filed: 1990-04-27
Abstract: PURPOSE:To avoid the collision of a roller with flappers by directly actuating the flappers with the roller, and selecting the positions of the flappers, accurately interlocked with the motion of the roller. CONSTITUTION:When subjected to a drive force in an arrow (2) direction, a roller 14A moves straight across an intersection 15N, while being pressed to a flapper 163. Also, when subjected to a drive force in a direction opposite to the arrow (2), the roller 14A similarly moves, while being pressed to another flapper 164. The roller 14A, therefore, does not change an advance direction toward the inside of another guide groove 15D, or does not contact the corner of the intersection 15N. As aforementioned, the flapper 163 or 164 is directly rotated with the roller 14A, and this rotation is transmitted to the other flapper as the rotation of the same direction and angle via a movement transmission mechanism. The positional selection of the flappers 163 and 164, therefore, can be accurately interlocked with the motion of the roller 14A, and the collision of the flatters 163 and 164 with the roller 14A can be thereby avoided.

Title: Heat exchanger tube
Inventor: KAWAGUCHI ISAO
IPC: F28F13/12
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To prevent heat transfer performance from being deteriorated and raise heat transfer efficiency by breaking down a boundary layer formed on an inner surface of a tube when fluid flows in the tube, in a heat transfer tube used in a boiler and other heat exchangers. SOLUTION: A twisted plate 2 supported at a top and bottom by fixtures 4 is rotatively pivoted within a longitudinal tubular path of a tube 1 for allowing a fluid (a) to be heated to flow and a center shaft 3 of the twisted plate 2 is inserted into engagement portions provided in a center of the fixtures 4 disposed at the top and bottom. When the fluid reaches this twisted plate 2 after flowing from downwards, direction of the flow is changed and is made to flow in a swirl and is pressed to an inner wall of the tube 1 so that a boundary layer formed on a face of the inner wall is broken away and is prevented from growing.  On the other hand the twisted plate 2 is subjected to a force of the fluid flow (a) and if magnitude of the force becomes greater than a frictional force of a bearing portion, the twisted plate 2 starts rotating to stir the fluid flow (a) so that exfoliation of the boundary layer is enhanced by stirring action together with the swirling flow.
