  • Publication number: 20240131538
    Abstract: An annular airflow regulating apparatus includes a cup-shaped element and an adjustment element. The cup-shaped element has a bowl and a bottom, integrated to form a first chamber. The bottom has a tapered channel parallel to an axis and penetrating through the bottom. A ring-shaped groove is disposed between the tapered channel and the bottom. The ring-shaped groove has an annular plane perpendicular to the axis. The adjustment element, having a tapered portion and second holes, is movably disposed in the cup-shaped element. The tapered portion protrudes into the tapered channel A tapered annular gap is formed between the tapered portion and the tapered channel. When the adjustment element is moved with respect to the cup-shaped element, a width of the tapered annular gap is varied, and thereupon a flow rate and velocity of the process gas would be varied accordingly.

  • Publication number: 20210199235
    Abstract: A tightening structure of a musical instrument stand includes stationary or immovable member and a movable member. The movable member includes a cylindrical shaft extending outward in an axial direction. One side of the immovable member has a recess. A bottom of the recess forms a semi-circular arc with a radius of curvature corresponding to that of the shaft. When the shaft is inserted into the recess it abuts against the bottom of the recess. The immovable member has a screw hole communicating with the recess. The screw hole is perpendicular to the axial direction of the cylindrical shaft. A fastening bolt is screwed into the screw hole. One end of the first fastening bolt is inserted into the recess and has a flared end portion to press against the shaft, and another end is connected with a handle. By rotating the handle, the flared end portion is drawn against the shaft, thereby rendering the movable member stationary.
