Abstract: This invention provides a single cascade multistage turbine that has a compact turbine structure having only a single cascade, and enables power to be extracted efficiently in the same way as a multistage turbine having multistage rotor vanes. The working fluid supplied through the supply duct 3 flows on one side of the single cascade of rotor vanes 2 to one part of the circumference direction of the rotor vanes 2, and after passing through the rotor vanes 2 it passes through the circulation ducts 4a and 4b and returns to the former side of the rotor vanes 2. The circulation ducts 4a and 4b consist of exhaust duct members 6a and 6b, return duct members 7a and 7b, and inflow duct members 8a and 8b. Using the circulation ducts 4a and 4b this circulation process is repeated at least once whereby the working fluid is again passed through the rotor vanes 2 at a slightly different position in the circumferential direction of the rotor vanes 2.

Abstract: This invention provides a multi-fan system separated core engine type turbofan engine in which high pressure air is used as the working fluid for a turbine which drives a fan, thereby reducing the manufacturing costs of the turbofan engine and simplifying the constitution thereof. A turbine for driving a fan 11 which is provided in a propulsion device 3 of the multi-fan system separated core engine type turbofan engine 1 is an air turbine 13 which is driven by the supply through a duct 9 of a part of high pressure air compressed in a compressor 5 of a core engine 2. Since the working fluid of the air turbine 13 for driving the fan 11 is not high temperature combustion gas, there is no need to use expensive heat-resistant material for the turbine, and thus the propulsion device 3 can be manufactured at low cost, the constitution thereof can be simplified, and operational control can be ameliorated.

Abstract: The present invention relates to a system and methodology to reduce size, weight and cost, improve data processing rates and serviceability, and accommodate higher I/O multi-chip modules (MCMs) for printed circuit board (PCB) assemblies employed in the electronics industry. This is accomplished by selecting low cost, pre-assembled, plastic chip type MCMs for constructing a daughter card where the daughter card material can accommodate high density lines and spaces. Optical interconnects are employed between the daughter card and the motherboard to provide a high speed interface that is substantially not effected by contaminates or limitations associated with electrical lead wires and solder bonds. The result is a high performance card that meets current and projected future demands in signal processing.

Abstract: A low-noise separated core engine type turbofan engine is provided in which noise generated by a control propulsion device is reduced by using high pressure air as the working fluid of a turbine for driving a control fan used in the attitude control of the airframe. A control fan 17 of a separated core engine type turbofan engine 1, which is comprised in a control propulsion device 4 provided for attitude control of the aircraft, is driven by an air turbine 19 which uses as working fluid high pressure air compressed by a compressor 6 of the core engine 2 and supplied through a duct 10.

The present invention offers a glycosaminoglycan-functionalized polymer protein composite produced by combining a cell-adhesive protein with a glycosaminoglycan-functionalized polymer obtained by incorporating a carbohydrate chain containing a structure corresponding to at least a portion of a glycosaminoglycan backbone into a vinyl polymer main chain, as well as a cell culture substrate and a material for tissue reconstruction treatments comprising the composite.

Abstract: A gas pressure-reducing valve includes a pressure-reducing chamber for generating a gas pressure that acts on one surface of a diaphragm, a valve body that can sit on a valve seat having in its central part a valve hole communicating with the pressure-reducing chamber, and a spring biasing the diaphragm in a direction that detaches the valve body from the valve seat. A valve housing is formed by conjoining a body, a partition, and a cover. The partition forms the pressure-reducing chamber between itself and the body and forms a pressure action chamber between itself and the diaphragm. The cover forms the spring chamber between itself and the other surface of the diaphragm and has the peripheral edge of the diaphragm clamped between itself and the partition. The partition has a through hole for allowing the valve stem to run through in an airtight and axially slidable manner and a communicating hole for providing communication between the pressure action chamber and the pressure-reducing chamber.
