IPC: B21D53/06
Filed: 1988-06-20
Abstract: PURPOSE:To improve the evaporating/condensing performance of a heat transfer tube by providing many notches in parallel or crosswise on a fin or the fin and a groove. CONSTITUTION:A diameter reducing die 5 and a floating disk 6 are provided, and also, grooved plugs 8, 9 for forming grooves in the reverse direction to each other in a coupling rod 7 of a disk 6 are provided. A tube 1 is brought to diameter reduction by the die 5, and thereafter, many grooves and fins 4, 2 are formed on the inside surface of the tube 1 through the plugs 8, 9 and form rolling rollers 10, 11. In this case, the second plug 9 crushes the groove which has been formed by the first plug 8, and forms many notches 3 for intersecting with the fin 2. In such a way, since many notches being in parallel to or intersecting with the fin 2 and the groove 4 are formed, the notch 3 improves nuclear boiling at the time of evaporation, slant faces of the fin 2 and the groove 4 by the notch make an acute angle and the condensability is improved. Accordingly, the evaporating/condensing performance of the heat transfer tube 1 is improved.

Title: Perspective distortion inspecting method of transparent plate
Inventor: OKAFUJI MASAHARU
IPC: G01B11/24
Filed: 1981-09-24
Abstract: PURPOSE:To exactly detect only an unsuitable perspective distortion, by varying a distortion detecting sensitivity in accordance with a part of a substance to be inspected, when processing a video signal of a transmission image. CONSTITUTION:Light is projected to a substance to be inspected 1, and its transmission image is reflected on a screen 6. This transmission image is picked up by an industrial television camera, and its video signal is sent to a signal processor 8. Subsequently, the processor 8 slices a differential signal of the video signal by a low level, as for a part of the substance to be inspected 1 whose small distortion must also be detected, and slices said signal by a high level, as for a part whose small distortion can be allowed. That is to say, in a main part, the distortion detecting sensitivity is raised, and in other part than the main part, the detecting sensitivity is lowered. This detecting sensitivity is switched by a microcomputer 10. In this way, only a suitable perspective distortion can be detected exactly.
