摘要:
The invention provides a reaction apparatus capable of efficiently causing a reaction, and a fuel cell system and an electronic device that include such a reaction apparatus. A reaction apparatus (1) includes a reformer (4), a CO remover (5) and a connecting portion (6) that connects the reformer (4) and the remover (5). The reformer (4) has a reforming reaction chamber (31) and a reformer combustion chamber (30) that generates heat to be supplied to the reforming reaction chamber (31), which (30, 31) are adjacent to each other with a partition interposed therebetween. The CO remover (5) has a removing reaction chamber (35) and a remover combustion chamber (34) that generates heat to be supplied to the removing reaction chamber (35), which (34, 35) are adjacent to each other with a partition interposed therebetween. The reformer (4) and the CO remover (5) are arranged spaced apart from each other, at least one of which is configured by combining ceramic parts (11, 12) and a reformer lid member (15) and a remover lid member (16), and heaters (48, 49) are disposed so as to face the ceramic parts (11, 12).

A package for accommodating a semiconductor element includes a heat releasing member having a mounting portion for a semiconductor element, a frame having a wiring conductor, and a lid attached so as to cover the mounting portion. In the heat releasing member, a plurality of through-metal members made of a copper are buried in the mounting portion of a substrate made of a matrix of tungsten or molybdenum and copper to another surface. Copper layers are joined at least to upper and lower surfaces of a portion in which the through-metal members are buried, and a cross-section area of each of the through-metal members is gradually increased from the center side of the substrate to a joint portion with the copper layers.

A novel terminally modified imide oligomer having excellent solubility in organic solvents, excellent solution storage stability, and excellent molding properties such as low melt viscosity. Also, a varnish obtained by dissolving the terminally modified imide oligomer in an organic solvent; a cure product obtained by using the terminally modified imide oligomer and having excellent thermal and mechanical characteristics such as heat resistance, elastic modulus, tensile strength at break and tensile elongation at break; a prepreg; and a fiber-reinforced laminate.

A package for receiving electronic part has a heat radiating plate having a mounting area where the electronic part is mounted at a center portion of one main surface, a frame body adhered to the one main surface to surround the mounting area, and a wiring conductor derived from the inside to the outside of the frame body. The heat radiating plate has a metallic base body, a metallic body filling inside of the metallic base body, and a metal layer deposited on the metallic base body and the metallic body. The mounting area is formed on the metal layer so as to be located above the metallic body, both of the metallic body and the metal layer have higher thermal conductivity than the metallic body, and both of the frame body and the metallic base body have a smaller coefficient of thermal expansion than the metal layer.

The invention provides a carbon fiber-reinforced composite material including reinforcing fibers which are continuous carbon fibers in the form of a unidirectional (UD) material, a woven fabric, or a knitted fabric, and a matrix resin including a modified polyolefin resin, thereby achieving better adhesion and mechanical strength. The matrix resin forms a polyphase structure having a sea-island structure which has an average island (independent phase) diameter of not greater than 0.5 μm. The composite material includes as a matrix resin a modified polyolefin resin obtained by, for example, graft-modifying a polyolefin resin with a monomer that contains an ethylenic double bond and a polar group in the same molecule; and includes as reinforcing fibers continuous carbon fibers. For example, the fiber-reinforced composite material is obtained by stacking the modified polyolefin resin and carbon fibers in a mold with a predetermined shape, and impregnating the carbon fibers with the modified polyolefin resin in a molten state under pressure, followed by cooling and curing.
