    摘要: A movable finger for prostheses, having a base a first intermediate portion connected to the base, a second intermediate portion connected to the first intermediate portion, and a fingertip connected to the second intermediate portion. The prosthesis further includes a first intermediate portion bending mechanism for actuating an actuator disposed in the base to pull a first wire to turn an eccentric member, a second intermediate portion bending mechanism for pulling a second wire wound around a pulley disposed as a movable pulley in the first intermediate portion by the eccentric member, whereby the pulling and bending of the second intermediate portion is by a third wire connected to the pulley, and a fingertip bending mechanism for pulling and bending the fingertip by a fourth wire connected to the first intermediate portion, whereby the pulling and straightening is by a fifth wire.

    摘要: An apparatus and method capable of accurately estimating a participant's muscle state are provided. In order to solve this problem, a muscle state estimation device 1 for estimating the state of a participant's muscles is provided. The muscle state estimation device 1 comprises a circumference sensor 2 that measures the circumference of the muscle, a myopotential sensor 3 that measures the electric potential generated by the activity of the muscle and a muscle state estimation unit 4 that calculates the muscle state such that an evaluation function, of which variables are the deviation of the circumference measured by the circumference sensor 2 from the circumference model that defines the relationship between the muscle state and the circumference and the deviation of the electric potential measured by the myopotential sensor 3 from the muscle tension model that defines the relationship between the muscle state and the electric potential, is minimized.

    摘要: A small plasma source that enables highly efficient discharge in an ultra-high vacuum state includes a first magnet, a second magnet arranged so that a second magnetic pole faces the first magnetic pole of the first magnet, a third magnet having the second magnetic pole directed in the same direction as the first magnetic pole of the first magnet and arranged to surround the first magnet, a fourth magnet having the first magnetic pole different from the second magnetic pole facing the second magnetic pole of the third magnet and arranged to surround the second magnet, a first electrode provided on sides of the first magnetic pole of the first magnet and the second magnetic pole of the third magnet, a second electrode facing the first electrode and provided on sides of the second magnetic pole of the second magnet and the first magnetic pole of the fourth magnet, and a third electrode arranged between the first electrode and the second electrode. A value obtained by dividing a shorter distance between a distance between the first magnet and the second magnet and a distance between the third magnet and the fourth magnet by an average value of thicknesses of the first to fourth magnets is 1 or more and 10 or less.
