摘要： One object of the invention is to provide an electric walking assistance device with which it is possible to prevent a user from falling down, and to provide a program and method for controlling the electric walking assistance device. A power-assisted rollator 100 according to the invention includes a motor 320 powered by a battery 310. A control unit 400 performs an assist control of revolutions of a pair of rear wheels 230 through the motor 320. When it is determined that a rotational acceleration of the pair of rear wheels 230 is equal to or larger than a predetermined value, a speed limiting unit 500 or a control brake unit 700 limits the rotational acceleration of the pair of rear wheels 230.

摘要： This invention relates to a technique for hermetically sealing an artificial leg including a cylinder device. A shell structure surrounds the outside of the cylinder device. The cylinder device is not entirely received within the shell structure, but a rod member extends to the outside of the shell structure from the cylinder body within the shell structure and a part of the rod member is located outside the shell structure. In this invention, the rod member, which extends from the inside to the outside of the shell structure, is hermetically sealed at the periphery thereof by a bellows packing member. The bellows packing member comprises an inner bead, an outer bead which concentrically surrounds the outside of the inner bead, and a bellows packing body part which connects the inner and outer beads. The bellows packing body part includes corrugations, and each corrugation is less curved than an imaginary circle formed between the outer bead and the inner bead and is configured in such a manner that both ends of the corrugation reach the outer bead or are located at positions closer to the outer bead than the inner bead.

摘要： The present invention provides a detection device for detecting a load and moment and capable of increasing the output by a strain gage. The detection device is provided with a characteristic sensor block. The sensor block includes a base having an axis extending in the direction of a load to be detected, a front side wall raised from the base at a position offset from the axis of the base, a rear side wall raised from the base at a position offset from the axis of the base in the direction opposite the front side wall, and an upper wall for connecting the upper end of the front side wall and the upper end of the rear side wall. The sensor block supports each strain gauge on the upper surface of the upper wall. The upper wall includes a center portion located at the center between the front side wall and the rear side wall, a first portion located between the center portion and the front side wall, and a second portion located between the center portion and the rear side wall. The first portion and the second portion, which support the strain gauges, have a smaller thickness than the center portion and are relatively easily deformed or strained.
