  • Patent number: 11534359
    Abstract: The present invention provides an actuator-equipped knee ankle foot orthosis in which a control device calculates a thigh phase angle based on an angle-related signal detected by a thigh orientation detecting means at one sampling point, applies the thigh phase angle at that sampling point to an assisting force control data, which is stored in the control device in advance and indicates the relationship between the thigh phase angle and a size of the assisting force to be imparted to a lower leg-side brace, to obtain the size of the assisting force to be imparted to the lower leg-side brace at that sampling point, and executes operational control for an actuator unit such that the assisting force having the size is output.

  • Patent number: 11529579
    Abstract: A filtration device includes a first channel member, a second channel member, and a filter. The first channel member has a recess recessed inward from an outer wall surface. A groove is formed is the recess and has an opening in a recessed surface of the recess. First and second channels, each defined by a through-hole, are formed in the first channel member and are connected to the groove. A first connection part connects the groove with the first channel. The second channel member has a projection that detachably mates with the recess. The second channel member includes a discharge channel that has an opening in a projecting surface of the projection, the opening being located over the groove. The filter is disposed along the groove, and positioned at the opening of the discharge channel. When the first and second channel members are placed in a operative relationship, a third channel is formed by the projecting surface of the projection and the opening of the groove.

  • Patent number: 10421844
    Abstract: A self-assembled monolayer is formed on the surface of a molded article without roughening the surface of the molded article to thereby perform treatment for preventing a biochemical substance from being adsorbed, for example, on a microchip substrate, and imparting functionality of immobilizing a biofunctional molecule thereto. The surface of a cyclic olefin resin molded article, for example, a microchip substrate, is irradiated with vacuum ultraviolet light having a center wavelength of 172 nm from an excimer lamp to activate a portion serving as a flow channel in the substrate. Next, the molded is immersed in a tank filled, for example, with a fluorine compound solution, and a SAM film that is a self-assembled monolayer is formed on the surface activated by ultraviolet radiation.
