  • Patent number: 10954075
    Abstract: The object of the present invention is to provide a novel conveying device with which it is possible to easily adjust a conveying amount of articles in a trough using a restricting plate, and a combination weighing apparatus having the conveying device. A conveying device to convey articles in a trough has a restricting plate to restrict a flow of the articles in the trough and the angle at which the restricting plate faces the articles is variable. With this configuration, there is no need to prepare a plurality of restricting plates that have different shapes and materials or to exchange such a plurality of restricting plates in the same manner as in a conventional device because the conveying amount in the trough can be adjusted merely by varying the angle at which the restricting plate faces the articles.

  • Patent number: 8939753
    Abstract: The high straightness arrow in the present invention is designed to improve the straightness of the archery arrow by adopting new manufacturing technique and method. Chamber and post are made of dissimilar metals and the chamber includes a wall that creates an external housing and defines an internal airspace. Once the post with shaft is positioned through chamber, nuts are tightened securely, forming an assembly, to straighten post. Due to the different coefficients of thermal expansion of chamber and post, when they are heated simultaneously, the chamber expands more than the post, creating a natural tension along post which results in a near perfectly straight shaft. As the assembly cools, the post and chamber return to their original length, yet the shaft retains its straightened form and thus this manufacturing process yields an arrow shaft that is straighter than shafts made of the same materials but with a traditional manufacturing technique.
