  • Patent number: 10812927
    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.

  • Patent number: 10756372
    Abstract: A first proton-donating layer (20a) is a layer having a proton-donative functional group on the surface, for example, a silicon oxide layer. A second proton-donating layer (20b) is also a layer having a proton-donative functional group on the surface, for example, a silicon oxide layer. Negative surface charges are formed on the main surface section of a first base (10a) and the main surface section of a second base (10b), and these negative charges increased the proton conductivity in an aqueous solution fed to a nano channel. Although, in the aqueous solution, proton migration through hopping between water molecules contributes to its diffusion, the negative charges formed on the main surfaces of the bases (10a, 10b) attract protons in the aqueous solution, and the conduction of protons is efficiently achieved in “high-speed transfer regions” formed in the vicinity of the proton-donating layers (20a, 20b).

  • Patent number: 10748776
    Abstract: In the present invention, a contact layer formed of a material having an electron concentration of less than 1×1022 cm?3 is directly provided on a surface of a semiconductor crystal having an n-type conductivity with a band gap of 1.2 eV or less at room temperature. Consequently, the wave function penetration from the contact layer side to the semiconductor surface side is reduced. As a result, the formation of the energy barrier height·?B due to the Fermi level pinning phenomenon is much suppressed. It is possible to achieve the contact with a lower resistivity and with high ohmic properties.
