Disc integration

Abstract: Location and feed mechanism of disc integration toothbrush processing equipment belongs to toothbrush processing equipment technical field, and table surface's central point puts and is equipped with rotatable disc pivot, and disc pivot top is equipped with the disc of fixing mutually with it, and disc pivot outside is equipped with the disc holder of fixing with table surface, and the equipartition has a plurality of toothbrush anchor clamps on the circumference of disc, all is equipped with the locating hole between toothbrush anchor clamps and the toothbrush anchor clamps, last feed mechanism and the positioning mechanism of still being equipped with of table surface, the utility model discloses simple structure, the theory of operation is clear, and the interact of adoption locating pin and locating hole realizes the accurate positioning of disc, has made the foreshadowing for feed mechanism's material loading process, compares with traditional production technology, and positioning accuracy is higher for this method, and it is tightly more stable to go up the feed collet, has guaranteed the orderly linking between each process, has eliminated the not high product defects who brings of positioning accuracy, and the work efficiency of equipment can obtain improvement by a wide margin.

Abstract: We study surfaces of revolution in the three dimensional Euclidean space with two distinct axes of revolution. As a result, we prove that if a connected surface in the three dimensional Euclidean space admits two distinct axes of revolution, then it is either a sphere or a plane.

Abstract: The utility model provides a disc integration machine with multiple toothbrush manufacturing procedure, belongs to toothbrush processing equipment technical field, includes the quick -witted workstation of disc integration that comprises table leg and mesa, the central point of mesa top puts and is equipped with rotatable disc pivot, is equipped with the disc of fixing mutually with it in the disc pivot, and the equipartition has the toothbrush anchor clamps on the circumference of disc, and toothbrush anchor clamps below is equipped with feed mechanism, ping mao mechanism, sanding machine structure, stamping mechanism and unloading mechanism along the clockwise of disc in proper order, the utility model discloses simple structure, the theory of operation is clear, and the last mode that adopts the rotatory work of disc of overall structure collects material loading, flat hair, grinds hair, stamping and unloading process in an organic whole, accomplishes each item process at the in -process that the disc is rotatory, has reduced manpower and equipment cost that the toothbrush was made, makes efficiency and has obtained promotion by a wide margin.

Abstract: In this paper, we investigate the surfaces of revolution with light-like axis satisfying some equation in terms of a position vector field and the Laplacian with respect to the non-degenerate third fundamental form in Minkowski 3-space. As a result, we give some special example of the surfaces of revolution with light-like axis.
