  • Patent number: 12059665
    Abstract: An active carbon molded body that comprises a plurality of active carbon granules that are formed from aggregates of active carbon particles. The active carbon granules include a fibrous granulation binder. The active carbon molded body is formed as a result of the plurality of active carbon granules being aggregated by means of the fibrous granulation binder in the active carbon granules. The present invention is also an active carbon molded body production method in which active carbon granules that have been formed by aggregating active carbon particles by means of a fibrous binder are molded by simultaneous application of heat and pressure without separate addition of a molding binder. The present invention thereby provides: an active carbon molded body that has high purification capacity and good production efficiency; and a production method for the active carbon molded body.

  • Patent number: 10362387
    Abstract: An acoustic resistor for use in an audio device includes a resin film having air permeability in a thickness direction of the resin film, and the resin film is a non-porous film having through holes formed to extend straight through the resin film in the thickness direction. This acoustic resistor is used in an audio device including: a transducing part that performs conversion between sound and an electrical signal and that includes an acoustic element; a housing enclosing the transducing part and having at least one opening; and a passage for gas that is present inside the housing and communicates with the opening and in which the acoustic element is placed. The acoustic resistor is placed between the opening and the acoustic element in the passage. The variation in properties of the acoustic resistor of the present disclosure can be made smaller than that of conventional acoustic resistors.
