A wave receiving plate is pivotably supported by a support device in the wave force generation system and includes a flexible plate in at least a part of the wave receiving plate.

Wave receiving plate and wave power generation system

The present technology provides an acoustic transmission member that includes a core layer layered between two skin layers, the skin layers being formed of a material having a higher elastic modulus than a material of the core layer. A thickness ds of the skin layers is formed such that Equation (1) is satisfied, where f is the center frequency of the transmission frequency band, cw is the acoustic velocity in the medium surrounding the acoustic transmission member, &#x3bb; is the wavelength corresponding to the center frequency in the medium, Cds is the longitudinal wave acoustic velocity in the skin layer, and n is a discretionary natural number. 

Acoustic transmission member and method of designing same

There is disclosed a composition which is layered in a reflective board to constitute a radio wave absorber. In this composition, an electroconductive titanium oxide is compounded with a substrate. With regard to the substrate, there may be used thermoplastic resin, thermosetting resin, rubber or elastomer.
