Abstract: There is provided a Ti alloy hollow club head which is more lightweight yet capable of realizing a better repulsion force by adjusting weight and thickness of a club head plate, with its strength ensured. Ribs are formed by chemically polishing the inner surface of a material of a crown plate to a 0.3 to 0.9 mm thickness, and a 0.3 to 4 mm width, and then first concave portions are formed to a 0.2 to 0.5 mm thickness. Thus, strength of the crown plate can be ensured by the ribs, while making the thickness thereof as thin as possible.

Abstract: A massage chair is adapted to give a massage to a user using a massaging element attached to a massaging unit. The massage chair comprises a body-shape-information acquisition section for acquiring body-shape information of the user based on loads imposed on the massaging element from respective regions of the user, a shoulder-position detection section for detecting a shoulder position of the user based on the body-shape information, and a shoulder-position identification section. The shoulder-position identification section is operable to thrust the massaging element in a direction for a target protrusion distance at the detected shoulder position while measuring a load imposed on the massaging element. Then, the shoulder-position identification section is operable, based on the measured load, to determine whether the detected shoulder position is a true shoulder position.

Abstract: A massaging device having an applicator driven by a plurality of driving unit to move along two or more different axes to generate a combined massaging action to be applied to the user's body. A controller holds individual speed data each defining a speed at which each of the driving units reciprocates the applicator along each of the different axes, and to control the driving units to reciprocate the applicator in accordance with the associated speed data. The controller controls the speed of the applicator along one of the axes independently from the speed of the applicator moving along another of the axes. Accordingly, the applicator's movements along the different axes can be free from being interfered with each other even being subject to a load, thereby assuring to continue the combined massaging action.

Abstract: In a chair massager, a stretching operation is performed with utilizing airbags which is expanded and shrunk, effectively. Airbags 3a, 3b, 4a, 4b, 5a and 5b which perform air-massage by expansion and shrinkage are disposed on a shoulder portion 3 and a lumbar portion 4 of a backrest 2, and a seat 5 of a main body 1 of the massager. Arm airbags 6a and 6b which perform air-massage by expansion and shrinkage are disposed on armrests 6 at both sides of the seat 5. In the stretching operation, for example, a shoulder airbag 3b on the shoulder portion 3 is expanded and shrunk in a state that an arm airbag 6a on one armrest 6 is expanded to hold an arm of the user 200. Thereby, the balance of a human body of the user 200 is broken down so that high stretch effect can be obtained.
