Abstract: A package has a cavity to be sealed by a lid. The package includes a heat sink having a coefficient of thermal expansion of 9 ppm/° C. or more and 15 ppm/° C. or less from 25° C. to 100° C. and a frame disposed on the heat sink, made of ceramics, and surrounding the cavity in plan view. An outer edge of the frame includes a first linear portion extending along a first direction, a second linear portion extending along a second direction orthogonal to the first direction, and a chamfer connecting the first linear portion and the second linear portion in plan view.

Abstract: A cogeneration system (10a) of the present disclosure includes an internal combustion engine (21), a first power generator (22), a first coolant circuit (23), a first heat exchanger (24), a second coolant circuit (25), a Rankine cycle power generation apparatus (26), and an exhaust gas supply path (40). The Rankine cycle power generation apparatus (26) includes a pump (27), an evaporator (28), an expander (29), a second power generator (30), and a condenser (31). The evaporator (28) heats and evaporates a working fluid with exhaust gas from the internal combustion engine (21). The exhaust gas supply path (40) delivers the exhaust gas from the internal combustion engine (21) to the evaporator (28) without allowing the exhaust gas to exchange heat with a liquid. The condenser (31) has a flow path (31a) through which the first coolant flows and which forms a part of the first coolant circuit (23).

Abstract: In an automobile body structure, since a center pillar connecting a side sill and a roof side rail is formed from a pair of CFRP laminates that oppose each other on the inside and the outside in the vehicle width direction and a plurality of metal plates that join the pair of CFRP laminates in the vehicle width direction so as to form a closed cross-section, a compressive load and a tensile load acting on the vehicle width direction inner face and the vehicle width direction outer face of the center pillar when the collision load of a side collision is inputted can be supported by carbon fibers of the pair of CFRP laminates, and out of plane deformation of a front face and a rear face of the center pillar, which is difficult to support with the CFRP laminate, can be prevented by the metal plate.

Abstract: Each base for fusing a snap-zipper male member and a snap-zipper female member, which form a snap zipper, onto a bag body is formed from a mixture of polypropylene and an ethylene copolymer obtained by copolymerizing ethylene and an .alpha.-olefin having a carbon atom ratio of 3 to 20, in which the ethylene copolymer has a weight average molecular weight/number average molecular weight of less than 3, density in the range from 0.850 g/cm.sup.3 to 0.935 g/cm.sup.3, melt index in the range from 0.3 g/10 min. to 15 g/10 min., and range of number of branching dependent on molecular weight of 0-5 branches/1,000 carbon. A bag with the snap zipper is structured to fuse the snap zipper through the bases onto the bag body.
