    摘要： The present invention provides an evaporated fuel gas adsorbent, an evaporated fuel gas trapping apparatus that uses the adsorbent, an activated carbon, and a process for producing the activated carbon. The evaporated fuel gas adsorbent is capable of improving adsorptivity and desorptivity by reliably preventing a temperature rise and a temperature fall caused by heat generated in response to the adsorption and desorption of evaporated fuel gas, is capable of achieving a size reduction of the device, and is capable of being easily produced. The activated carbon has high mechanical strength and high abrasive resistance, has many pores suitable to adsorb an organic solvent, especially, evaporated fuel gas, and has a high packing density. The activated-carbon producing process is industrially advantageous. The evaporated fuel gas adsorbent comprises an adsorptive material and latent heat storage mediums including containers each of which is made of a flexible film and in each of which a substance that absorbs or releases heat in response to a phase change is encased. The activated carbon is characterized in that a specific surface area calculated by a BET method (multipoint method) in a nitrogen adsorption isotherm determined from a nitrogen adsorption amount at liquid nitrogen temperature is 1000 to 2500 m2/g, in that a half-value width of a D-band peak in the neighborhood of 1360 cm−1 in Raman spectroscopic analysis is 120 cm−1 or less, and in that a half-value width of a G-band peak in the neighborhood of 1580 cm−1 in Raman spectroscopic analysis is 100 cm−1 or less.

    摘要： A material for improving the sound pressure level at the bass reproduction limit of the present invention is composed of an activated carbon having a cumulative pore volume of 0.4 ml/g or more for the pores each having a radius of 50 angstroms or less. Preferably, this activated carbon has a cumulative pore volume of 0.1 ml/g or less for the pores each having a radius of 7 angstroms or less. In particular, when a sound pressure level improving material in which the activated carbon has a cumulative pore volume of 0.5 ml/g or more for the pores each having a radius of 18 angstroms or less is installed in a cabinet of a loudspeaker device, the material alleviates pressure fluctuations of a gas within the cabinet caused by vibration of a loudspeaker, and thus a very good bass reproduction effect is attained. Moreover, in the case where a sound pressure level improving material in which the activated carbon has a cumulative pore volume of 0.4 ml/g or more for the pores each having a radius of 18 to 50 angstroms is installed in the cabinet, a loudspeaker device having a good bass reproduction effect even in an atmosphere of high humidity is obtained.
