  • Patent number: 11583463
    Abstract: A hemiplegic forearm function recovery training device includes a forearm mounting part (2) on which a forearm (S) is to be mounted. The forearm mounting part (2) includes a mounting body (20), an inner frame portion (2B), an outer frame portion (2A), and a control part. The mounting body (20) has a forearm fixing portion (22) on which the forearm (S) is mounted and a gripping mechanism (23) capable of being gripped by a hand of the forearm (S). The inner frame portion (2B) is fitted to the mounting body (20) and is rotatable around the forearm (S). The outer frame portion (2A) guides the inner frame portion (2B) in a rotation direction thereof. The control part performs a series of controls that repeatedly causes normal rotation, stop, reverse rotation, and stop of the inner frame portion (2B) while acquiring rotation angle information of the inner frame portion (2B).

  • Patent number: 6684447
    Abstract: A cleaning sponge roller is made of a polyvinyl acetal-based porous sponge having elasticity in a wet state and comprises a generally cylindrical roll body and a plurality of protrusions molded integrally on the periphery of the roll body. The cleaning sponge roller rotatingly cleans a material to be cleaned by contacting the top portions of the protrusions with the surface of the material and brushing off polishing residues found on the surface of the material. Each of the protrusions has a tapered protruding base portion extending from the periphery of the roll body, and a protruding end portion having almost the same sectional shape from the top end surface of the protruding base portion to the top portion.
