Abstract: A training mechanism for water-based lower-limb rehabilitation, including two leg training sub-mechanisms. Each leg training sub-mechanism includes a hip joint training device, an adjustable thigh plate, an adjustable shank plate, a knee training device, an ankle training device and a pedal. The hip joint training device, knee training device and ankle training device are connected to a remote control motor box through a Bowden cable assembly, respectively. A robot including the training mechanism is also provided, whose power source is arranged outside the water, and the power is supplied to the training mechanism through the Bowden cable assembly.

Abstract: Provided is a capacitive sensor device capable of detecting the position and magnitude of external force with high accuracy. Employed is a capacitive sensor which comprises pairs of electrodes arranged in a matrix, each of the pairs of electrodes being disposed to face each other with a distance therebetween, and an elastically deformable dielectric layer arranged between each of the pairs of electrodes. A capacitance measuring part measures capacitance of respective electrode pair groups in a plurality of combinations each comprising more than one of the pairs of electrodes including a selected one of the pairs of electrodes. An external force calculating part calculates the magnitude of external force applied to the position of the selected pair of electrodes based on a plurality of measured values of the capacitance.

Abstract: An expression display device includes an electrostrictive element having a stretched dielectric layer, and electrodes disposed with the dielectric layer interposed therebetween. The dielectric layer has a crosslinked material layer made of a three-dimensional crosslinked material synthesized from a rubber polymer and a metal alkoxide compound or a compound having a hydrosilyl group. The electrodes contain an elastomer and a conductive material. The expression display device displays a facial expression as the dielectric layer extends and contracts according to a voltage that is applied between the electrodes.

Abstract: To provide an actuator which is easily made a small size and flexible, and has a large displacement. The actuator comprises a rod-shaped actuator element, having one axial end thereof fixed, including a dielectric film made of a dielectric elastomer and a plurality of electrodes arranged via the dielectric film, in the actuator element, the dielectric film extends as a voltage applied across the electrodes becomes large, and a load member connected to the other axial end of the actuator element and fixed in a state in which the actuator element is permitted to be extended axially, characterized in that making large the voltage applied across the electrodes causes the dielectric film to be extended, whereby the actuator element is extended axially according to the tension of the load member.

Abstract: A vibration damping device for use in an internal combustion engine including: a rigid housing having a hollow space; an independent mass member housed within the hollow space; and at least one rubber sleeve being independent of the housing and the mass member and being disposed within an empty space between the housing and the mass member so as to extend over an entire circumference of the empty space with a constant thickness dimension. An inside tiny gap is formed between an inner circumferential surface of the rubber sleeve and an outer surface of the mass member over an entire circumference thereof, while an outside tiny gap is formed between an outer circumferential surface of the rubber sleeve and an inner surface of the housing over an entire circumference thereof at room temperature of 25° C.

Abstract: A vibration damping device including: at least one elastic plate member adapted to be superposed against a surface of a vibrating member to be damped, and having a natural frequency tuned to a frequency band to be damped in the vibrating member; and a positioning member for positioning the elastic plate member with respect to the surface of the vibrating member.
