    摘要： A method for post-cleaning finish drying is provided, by which finish drying of industrial parts can be conducted without leaving residues or corroding the cleaned material. In this method, finish drying can be performed without the use of freon being a cause of destruction of the ozonosphere. Preferably, a cleaned material is dipped (rinsed) in a low molecular weight siloxane having a content of organic compounds, such as dodecamethylpentasiloxane, of less than 0.01% by weight, taken out and dried. Also, preferably, the material rinsed with the low molecular weight siloxane is subjected to a vapor cleaning using a perfluorocarbon compound.

    摘要： An ultrasound transducer includes a substrate and a lower electrode layer, a lower insulating layer, an upper insulating layer, and an upper electrode layer. The lower insulating layer and the upper insulating layer are arranged to be opposed to each other via an air gap section. The upper insulating layer and the lower insulating layer are different in a material and thickness and satisfy Equation 1 below. In Equation 1, K1 represents a relative dielectric constant of the lower insulating layer, K2 represents a relative dielectric constant of the upper insulating layer, T1 represents thickness of the lower insulating layer, T2 represents thickness of the upper insulating layer, ρ1(x) represents a charge density distribution in the lower insulating layer, and ρ2(y) represents a charge density distribution in the upper insulating layer. 1 K ⁢ ⁢ 1 ⁢ ∫ 0 T ⁢ ⁢ 1 ⁢ x × ρ ⁢ ⁢ 1 ⁢ ( x ) ⁢ ⁢ ⅆ x = 1 K ⁢ ⁢ 2 ⁢ ∫ 0 T ⁢ ⁢ 2 ⁢ y × ρ ⁢ ⁢ 2 ⁢ ( y ) ⁢ ⁢ ⅆ y ( Equation ⁢ ⁢ 1 )
