Abstract: According to one embodiment, a connector fixing structure includes a printed circuit board assembly, and a base to which the printed circuit board assembly is attached. The printed circuit board assembly has a connector mounted on a printed circuit board, and a connector panel attached to the printed circuit board. The connector has a connector main body, a front flange projecting from the connector main body, and a rear flange projecting from the connector main body. The connector panel has a provisional fixing portion which is inserted between the front flange and the rear flange and provisionally fixes the connector to the connector panel. The base has a fixing portion which is inserted between the rear flange and the connector panel, thereby brings the front flange into contact with the connector panel and fixes the connector to the base, when the printed circuit board assembly is attached to the base.

Abstract: A method by which high temperature properties of a ductile iron alloy, including creep and LCF properties, can be increased for pressure-containing components that are subject to creep and low cycle fatigue. The method comprises modifying the ductile iron alloy to contain 0.4 to 0.8 weight percent molybdenum. A casting of the modified ductile iron alloy is produced and then annealed at a temperature of at least 725° C. for not less than five hours to eliminate carbides and/or stabilize pearlite in the casting. The annealed casting of the modified ductile iron alloy exhibits improved creep resistance and low cycle fatigue properties in comparison to an identical casting of a ductile iron alloy that does not contain molybdenum.

Abstract: A heat exchanger comprises a plurality of flat tubes for heat exchange between a first fluid flowing inside the tubes and a second fluid flowing outside the tubes. A pair of hollow headers is connected to the ends of the flat tubes. An inlet and outlet are provided in the headers for introducing the first fluid into the flat tubes and discharging it therefrom. Each header is composed of at least two parallel tubes with substantially circular cross-section, two adjacent tubes having integrated wall portions, thereby providing a substantially flat header.

Abstract: A core for use in casting a turbine bucket including serpentine cooling passages is divided into two pieces including a leading edge core section and a trailing edge core section. Wall thicknesses at the leading edge and the trailing edge of the turbine bucket can be controlled independent of each other by separately positioning the leading edge core section and the trailing edge core section in the casting die. The controlled leading and trailing edge thicknesses can thus be optimized for efficient cooling, resulting in more efficient turbine operation.
