    摘要: A diffracted sound reduction device includes: a reproduction speaker that outputs reproduced sound having properties indicated by an input signal; control speakers each of which reproduces corresponding one of control signals, the diffracted sound being a part of the reproduced sound and arriving at corresponding one of the control points except the control point at the listener's position; and control filters each of which filters the input signal to generate corresponding one of the control signals. Each of the control points faces a corresponding speaker from among the reproduction speaker and the control speakers. Each of the control filters generates the corresponding one of the control signals so that a sound pressure of the diffracted sound at corresponding one of the control points is lower than a sound pressure of direct sound that is a part of the reproduced sound which arrives at the control point of the listener's position.

    摘要: A noise control device includes a signal processor that detects a noise outputted from a noise source, and generates a control signal based on the noise and a control acoustic system that generates a control sound for canceling the noise, based on the control signal outputted from the signal processor. The noise control device also includes an output correction section that corrects the control signal outputted from the signal processor, in a frequency band for which a noise control process time τ, which is a time period from when the noise is outputted from the noise source to pass through the signal processor and the control acoustic system to when the control sound reaches the control point, is larger than a noise transfer time T, which is a time period from when the noise is outputted from the noise source to when the noise reaches the control point via the noise transfer system (τ>T).

    摘要: To provide a simple process for producing graphene.A graphene production apparatus 100 has a vessel 10 and, attached thereto, an immersion electrode 20 and a non-immersion electrode 30. The immersion electrode has an electrode covering 20c and an electrode main body 20e, and the non-immersion electrode has a covering 30c and an electrode main body 30e. An argon-feeding conduit 40 is disposed so as to inject argon into the vessel 10 around the electrode main body 30e. Ethanol is supplied in such an amount that the liquid surface completely covers the electrode main body 20e of the immersion electrode 20 and does not reach the electrode main body 30e of the non-immersion electrode 30. The electrode main body 20e is formed from, for example, iron, nickel, or cobalt. Thus, a 60-Hz AC voltage is applied to the electrode main body 20e immersed in the liquid; i.e., below the ethanol surface, and to the electrode main body 30e located above the liquid, while argon gas is supplied through the argon-feeding conduit 40. As a result, a gas-liquid plasma generates, to thereby induce decomposition of ethanol, etc., whereby graphene is yielded. The graphene disperses in ethanol.
