Abstract: A power conversion device includes two input terminals, a first converter, and two first output terminals configured to output power converted by the first converter. The first converter includes a switching circuit, a flying capacitor, and a reactor. The power conversion device includes a second converter configured to perform power conversion on a voltage across the flying capacitor as an input voltage, two second converter input terminals electrically connected to two ends of the flying capacitor, and two second output terminals configured to output power converted by the second converter. The second converter includes a primary-side circuit and a secondary-side circuit. The second converter is an isolated DC/DC converter in which the primary-side circuit and the secondary-side circuit are electrically isolated from each other.

Abstract: Provided are a structure for producing a high-quality single crystal diamond, and a method for manufacturing the structure for producing diamond. A structure for producing a diamond is composed of a base substrate and an Ir thin film formed on the base substrate. The thermal expansion coefficient of the base substrate is 5 times or less of the thermal expansion coefficient of diamond and the melting point of the base substrate is 700° C. or higher. The peak angle in the X-ray diffraction pattern of the Ir thin film is different from the peak angle in the X-ray diffraction pattern of the base substrate.

Abstract: An oxygen sensor element made of a ceramic sintered body detects oxygen concentration based on an electric current value measured when a voltage is applied. The ceramic sintered body has a composition formula LnBa2-xSrxCu3O7-δ generated by substituting any element selected from group 2 elements in the periodic table, such as strontium (Sr), for a part of a composition formula LnBa2Cu3O7-δ (Ln denotes rare earth element and δ is 0 to 1). Sr substitution quantity x should satisfy an inequality constraint 0

Abstract: The purpose of the present invention is to provide a cell culture substratum which has excellent resistance to liquid culture media and low cytotoxicity, can achieve a high cell adhesion ratio and a high viability of cultured cells, has excellent thermal stability, and is less likely to absorbs ultraviolet ray. A cell culture substratum which is provided with a substrate made from an inorganic material and has multiple concavo-convex structures on a culturing surface thereof, wherein, when the concavo-convex structures are measured with an atomic force microscope in accordance with JISB0601 and JISR1683 (measured area: a 1 μm-square, cut-off value of a low-pass contour curve filter: 1 nm, cut-off value of a high-pass contour curve filter: 170 nm), the average of the lengths of contour curve elements of the concavo-convex structures is 1 to 170 nm as measured in at least one direction (when a curve showing long-wavelength components that are blocked by the high-pass contour curve filter is converted to a straight line by the least square method, the average line is a line that is parallel with the straight line and indicates a height cumulative relative frequency distribution in the contour curve of 50%).

Abstract: Provided are a rotary device for fluid power generation and a fluid power generation device that are capable of converting the kinetic energy of a fluid to an electric energy. By utilizing a longitudinal vortex as a driving force, a rotary body such as a cylinder as a high-strength and tough wing-shaped member can be rotated, and power can be efficiently generated in a wide range of flow rate without letting the longitudinal vortex disappear even if the flow rate changes in a wide range. This rotary device for power generation includes a rotary body 3; and a wake body 8 that is a distance away from the rotary body 3 toward the downstream side of a flow direction 10 of the fluid, and has at least one crossover section at which the wake body 8 intersects with the rotary body 3.
