Abstract: A skin stimulation device includes: a first vibration member that is vibrated by excitation or that vibrates by itself; a vibration film that makes contact with the skin and transmits vibration as stimuli; and a first support member that supports the vibration film by a predetermined first surface and supports the first vibration member by a second surface opposing the first surface, and that has formed therein a first hole which penetrates from the first surface to the second surface and in which the area of a first opening on the first surface side is smaller than the area of the second opening on the second surface side. The vibration film is supported by the first support member to close the first opening. The first vibration member is supported by the first support member to close a second opening.

Abstract: A skin-stimulating device for imparting a stimulus to the skin, includes: a first film that bends when a voltage is applied; a plurality of first film-form electrodes provided on one surface of the first film so as to be separated from one another by a prescribed spacing; a second film that bends when a voltage is applied; a second film-form electrode provided on one surface of the second film; and a dielectric member molded from a dielectric rubber in the shape of a thin sheet in which a hole is opened, with other surface of the first film being affixed to a first surface that is a prescribed surface of the dielectric member, and the other surface of the second film being affixed to a second surface on the reverse side from the first surface.

Abstract: The present disclosure relates to a MEMS vibrator or the like that has excellent chemical resistance and an excellent mechanical strength and that is easily thinned. The present disclosure is a MEMS vibrator comprising: a vibrating film including a graphite film; and a silicon member supporting the vibrating film, the graphite film having a thickness of 50 nm or more and less than 20 ?m, and the graphite film having a Young's modulus along a graphite film plane direction of 700 GPa or more.

Abstract: A scroll member comprising a metallic end plate having a spiroidal groove on one side thereof, and a through-hole communicating with the groove, and a resin wrap joined to the groove of the end plate so as to protrude from the surface of the end plate. The wrap being formed by injection molding, and the through-hole and the groove being filled with part of the wrap.
