An object of the present invention is to provide a radio frequency power amplifier of multi stage amplifying method that is designed to reduce instability of output power caused by electromagnetic coupling of bias supply terminals and interconnections of each stage to thereby operate stably. Another object of the present invention is to provide a radio frequency power amplifier that is designed to reduce distortion of output power caused by electromagnetic coupling of bias supply terminals and interconnections of each stage to thereby provide high efficiency. The above objects can be achieved by providing a first interconnection connected to a terminal for supplying a voltage for collector driving to a power amplifying transistor, a second interconnection connected to a terminal for supplying a voltage for collector driving to a second transistor controlling a base bias voltage of the above transistor, and one or more ground parts for electromagnetic shield, wherein the first interconnection and the second interconnection are separated by one or more of the ground parts for electromagnetic shield.

A decomposition apparatus for decomposition of decomposition targets such as organic chlorinated compounds is provided. The decomposition apparatus includes a contact section with an internal space to allow a decomposition target to come into contact with and be taken into a liquid, a flow path to lead along with the liquid the decomposition target taken into the liquid to a position different from the internal space, a decomposing device positioned along the flow path in a state cut off from the outside air to decompose the decomposition target that has been led through the flow path, and a device to introduce to the contact section a liquid that contains products produced from the decomposition of the decomposition target by the decomposing device. The decomposing apparatus have plate-shaped electrodes that come into contact with and electrolyze the decomposition target that flows through the flow path, and wherein the surfaces of the electrodes are positioned within the decomposing device at an angle different from the flow direction of the liquid in the flow path, for example, perpendicular to the flow direction of the liquid in the flow path.

A thermoelectric conversion material and a thermoelectric conversion device having a novel structure of an increased figure of merit are provided by forming nano-wires of thermoelectric material in a smaller cross-sectional size. The thermoelectric conversion material comprises nano-wires obtained by introducing a thermoelectric material (semiconductor material) into columnar pores of a porous body. The porous body is formed by providing a structure in which columns of a column-forming material containing a first component (for example, aluminum) are distributed in a matrix containing a second component (for example, silicon or germanium or a mixture of them) being eutectic with the first component, and then removing the column-forming material from the structure. The average diameter of the nano-wires of the thermoelectric material is 0.5 nm or more and less than 15 nm, and the spacing of the nano-wires is 5 nm or more and less than 20 nm.

A method of forming, on a substrate, minute-sized columnar portions of a columnar structured material at minute intervals, and a columnar structured material formed by the manufacturing method. A columnar structured material is formed through an etching process in which a pattern of minute dots formed on the substrate is utilized as a mask. The pattern of the minute dots is obtained by introducing a mask material into columnar microholes of a porous film formed on the substrate and then removing the porous film. The porous film is formed by removing columnar substances from a structured material in which the columnar substances which are so formed as to contain a first component are dispersed in a matrix which is made of another component and is so formed as to contain a second component that can form a eutectic together with the first component.
