  • Flexible pipe coupling
    Patent number: 4401325
    Abstract: A flexible pipe coupling is disclosed. This coupling comprises a large diameter cylindrical hollow body, a pair of small diameter cylindrical hollow bodies each having one end portion disposed inside each end of the large diameter cylindrical hollow body on the same axial line, and an elastic sleeve member for connecting each end of the large diameter cylindrical hollow body to one end of each of the small diameter cylindrical hollow bodies. The elastic sleeve member is provided at its both ends adjacent to the cylindrical hollow bodies with protrusions each extending outwardly in the widthwise direction of the sleeve member at a radius of curvature corresponding to 0.1.about.0.4 times the thickness of the sleeve member, whereby the durability of the coupling is further improved.

  • Apparatus for analyzing the balancing function of the human body
    Patent number: 4122840
    Abstract: A person to be tested steps on a pair of foot steps, and a plurality of body load detectors sense the body load of the person, as applied to the foot steps. An arithmetic circuit receives the body load signals and provides difference signals which are displayed so that the person being tested can observe them. The person being tested sees body load distribution patterns on the display, and adjusts his body balance as a function thereof. Maximum-length linear shift register signals are provided which unbalance the body load distribution of the person being tested while standing on the foot steps. When the person observes these signals in the form of target signals, that person attempts to adjust the body load distribution so as to result in a balanced condition.
