Abstract: A power generation system includes: a prime mover; a magnetic gear generator configured to be driven by an input from the prime mover to generate power; a power converter connected to the magnetic gear generator; an operation mode switch unit configured to switch an operation mode of the magnetic gear generator to a step-out avoidance mode in response to that a step-out parameter indicating a risk of step-out of the magnetic gear generator exceeds a prescribed allowable range; and a reduction command unit configured to give the prime mover an input reduction command to reduce the input from the prime mover and configured to give the power converter a torque reduction command to reduce a generator torque of the magnetic gear generator, in the step-out avoidance mode.

Abstract: A beauty device that provides a desired massage effect in a simple and efficient manner is provided. The beauty device includes a main body including a handle portion to be held by a user, an arm portion provided to be pivotal relative to the main body, two rollers rotationally held by the arm portion, and an urging mechanism that urges the arm portion toward a reference position within a range of the pivot movement. The beauty device efficiently provides a desired massage effect simply by pressing the two rollers against the skin and moving the rollers to reciprocate without greatly changing the position of the handle portion with respect to the skin in any of advancing directions including the forward path and the return path.

Abstract: A shower head includes a handle and a head portion. The head portion includes shower holes. The handle includes an upstream bubble generator that generates minute bubbles in water. The head portion includes a downstream bubble generator that generates minute bubbles in water in the same manner as the upstream bubble generator. The upstream bubble generator includes a constriction and a tapered portion. The downstream bubble generator has a swirling flow mode. Since minute bubbles are generated on the upstream and downstream sides, the amount of minute bubbles mixed in water becomes larger. This allows for showering by effectively using the function of minute bubbles.

Abstract: A massager (1) includes a main body (2) that has a plate shape and applies a massage by sliding a peripheral edge (21) of the main body (2) on skin, and at least one rotating body (3). The rotating body (3) is disposed so as to protrude outward from the peripheral edge (21) of the main body (2). The rotation axis (31) of the rotating body (3) extends outward through the peripheral edge (21) of the main body (2).

Abstract: In electrical stimulation fitness wear, multiple electrode parts 30 are provided in a clothing portion, at positions that respectively face multiple target body parts such as to be respectively in proximity to the multiple target body parts, so as to provide electrical stimulation to the multiple target body parts, and the multiple electrode parts 30 each have a surface formed of a conductive polymer fabric 31. Multiple electrical cables 36 respectively connect the multiple electrode parts 30 to a connection part of a control unit electrically. The multiple electrode parts 30 include a first electrode part 30 to which a first electrical cable 36 is connected and a second electrode part 30 to which a second electrical cable 36 is connected. The first electrode part 30 and the second electrode part 30 are provided at separate positions such that a current can be applied to a certain body part between the electrodes.

Abstract: An aqueous skin care agent 1 contains 4 to 85 mass % of water, 13 to 80 mass % of a magnetic powder and a thickener. The magnetic powder contains a ferromagnetic ferrite as a main component and has a mean volume particle diameter being 20 to 100 ?m as determined from a particle size distribution obtained by a laser diffraction scattering method. The aqueous skin care agent 1 may contain a beauty component such as an iontophoretic component 3 and preferably contain 10 to 45 mass % of glycerin as the thickener.

Abstract: The present invention provides a sleeping apparatus which can improve the quality of sleep, by evaluating the quality of human sleep and presenting the control methods of the exercise forcing means based on the evaluation result. The sleeping apparatus comprises a body support part which supports the user's body, a sleep information detection means which detects said user's sleep information, and a memory part which stores said user's sleep information, wherein the sleeping apparatus comprises an exercise forcing means which forces said user's body to exercise, a sleep state evaluation means which evaluates said user's sleep state based on said user's sleep information, and a control means which can output control methods of said exercise forcing means based on the evaluation result from said sleep state evaluation means.

Abstract: A muscle electrostimulation device includes: a main body; a power source stored in the main body; an electrode unit that receives power from the power source; a controller that controls the supply of power to the electrode unit; and an operation unit that changes a control mode of the controller. The electrode unit includes a first and a second electrode group. The first group extends from the main body to be disposed on a right hand side of a person with respect to a center line of the main body. The second group extends from the main body to be disposed on a left hand side of the person with respect to the center line when the device is attached to the abdomen. The first and the second electrode group can be electronically connected via the person and include four or more electrodes in total.

Abstract: In an exercise instrument controller, a type determination unit specifies, from among a plurality of types, the type of exercise for which an exercise instrument is used. An association determination unit specifies association between a body part that is exercised and the exercise instrument based on the type that has been specified. A setting processing unit sets an operation detail of the exercise instrument based on user's manipulation. An instrument control unit controls, by transmitting information indicating an operation detail for each exercise instrument based on the association between the body part and the exercise instrument that has been specified and the operation detail that has been set, exercise by the exercise instrument. A display control unit controls a screen display regarding the association between the body part and the exercise instrument, the operation detail, and an exercising status.
