Abstract: The present invention provides a metal foam production method that enables a foaming process to be performed at low cost and enables controlling of the shape of metal foam. According to the present invention, a mold that transmits light and a precursor prepared by mixing a metal with a foaming agent are used, and a metal foam is produced by irradiating the precursor with a light transmitted through the mold to thereby heat and foam the precursor so as to obtain a metal foam, while controlling the shape of the metal foam by the mold.

Abstract: The present invention is a surface-modified carbon material including chemical addends added to the surface of graphene, such that a one-dimensional periodicity corresponding to a large number of addition positions of the chemical addends can be observed in a Fourier-transformed image of a scanning probe microscopic image of the surface of graphene. The surface-modified carbon material of the present invention has a bandgap and therefore can be used as a sensor capable of electronically controlling an operation or another electronic device.

Abstract: A spatial sound generation device including a storage (106) and a controller (102) and connected to a plurality of speakers (116) is provided. In the spatial sound generation device, referring to information indicating a movable sounding body, the controller varies a transfer characteristic for each time in accordance with movement of the sounding body and applies an inverse filtering to calculate a plurality of input signals for the respective speakers from a sound source signal indicating a sound emitted by the sounding body. The inverse filtering outputs the input signals into the speakers to form a three-dimensional acoustic wave front under boundary surface control in accordance with a transfer characteristic for a space in which the plurality of speakers are arranged.
