Abstract: A display device includes a liquid crystal panel, a rear frame and a rear cover disposed on a back side of the liquid crystal panel and including an opening, first protrusions on the rear frame, second protrusions on the rear frame and disposed on the side opposite from the opening, with the first protrusions being arranged between the opening and the second protrusions, a first size speaker capable of being mounted on the first protrusions, a second size speaker capable of being mounted on the second protrusions, and a covering surface on the rear frame and the rear cover.

Abstract: A speaker includes a diaphragm, a housing, and a sound blocking member. The housing fixes an edge of the diaphragm. The sound blocking member is disposed on a surface of the housing different from an audio output surface thereof and in the vicinity of the diaphragm.

Abstract: An adsorbent for radioactive nuclides incorporating fibrous activated carbon. The adsorbent includes fibrous activated carbon having good adsorption performance, inorganic fiber and inorganic binder. Therefore, the adsorbent exhibits good shape stability when it is formed into a molded piece, has good combustion performance, and is not liable to scattering of radioactive nuclides adsorbed thereon when it is incinerated.

Abstract: An adsorbent useful for the adsorption of radioactive nuclides which comprises fibrous active carbon having a specific surface area of 1,000 m.sup.2 /g or more and an equilibrium moisture regain of 10% or more at a relative humidity of 45%; and a process for the volume-reduction treatment of radioactive liquid waste which comprises subjecting radioactive liquid waste containing radioactive nuclides to an adsorption treatment using an adsorbent comprising fibrous active carbon having a specific surface area of 1,000 m.sup.2 /g or more, and subsequently subjecting the spent adsorbent to an incineration treatment at a temperature which is equal to or higher than the ignition point of the fibrous active carbon.
