Abstract: The invention provides a power turbine test apparatus able to significantly reduce the equipment cost and testing cost required for an independent operation test of a test object power turbine. The power turbine test apparatus for independently operating and testing a power turbine that drives a driven machinery using combustion gas or steam, comprises: an air compressor that supplies compressed outside air to a combustor positioned on a downstream side; a first air duct that guides the outside air compressed by the air compressor into the combustor; a combustor which combusts the compressed outside air and fuel to generate combustion gas; and a second air duct that guides the combustion gas generated by the combustor to the power turbine installed on the downstream side; wherein a rotating shaft of the power turbine and a rotating shaft of the air compressor are joined to each other, and power of the power turbine is recovered by the air compressor.

Abstract: There is provided a hybrid turbocharger that allows easy and quick attachment/removal of a coupling attachment boss to which an end section of a coupling is attached, thereby reducing the amount of operation time required for an overhaul of the turbocharger. The hybrid turbocharger includes: a turbine section that is driven by exhaust gas introduced from an internal combustion engine; a compressor section that is driven by the turbine section to pressure-feed outside air into the internal combustion engine; and a power generator having a rotating shaft coupled to a rotating shaft of the turbine section and the compressor section via a coupling.

Abstract: In an ATM cell multiplexing apparatus for assembling data, which arrives from multiple terminal lines, into cells, time-division multiplexing the cells and transmitting them to a network, traffic management is performed in each cell assembler, based upon service category and traffic, for every channel accommodated by the terminal lines, and traffic management on a per-cell-assembler basis is performed in an ATM bus scheduler taking into consideration service categories and traffic of all channels accommodated by the cell assemblers. Further, the ATM bus scheduler creates a main schedule table and a subschedule table, which is referred to after the main schedule table, for allocating more transmission privileges to a cell assembler that accommodates a CBR channel, and grants transmission privileges to the cell assemblers upon referring to the main schedule table and subschedule table.

Abstract: An ATM cell multiplexer is arranged so that in the up direction from the terminal equipments/ATM cell interfaces to the ATM switchboard the ATM bus scheduler allocates the transmission rights for each CLAD unit in accordance with a preset schedule table and predetermined service categories or traffic control for the transmission of cells, and in the down direction from the ATM switchboard to the terminal equipments/ATM cell interfaces the cells are broadcast to all of the CLAD units which decide for the reception of the cells as to whether or not the cells are addressed to themselves.

Abstract: In the present invention, a first and a second projector means projecting rotating laser beams rotating at a predetermined period are disposed at two predetermined fixed points, respectively. A first, a second and a third photodetection means are disposed on a moving body to detect the photodetection timings with which laser beams are detected, and to detect photodetection height positions of the rotating laser beams. The rotating angles of the two rotating laser beams from the reference azimuth are calculated on the basis of the outputs from the first, second and third photodetection means, and the positions and heights of the respective photodetection means are calculated from these data. Thus are the position and attitude angle of the moving body are measured with high accuracy, and these data are displayed on a real-time basis.
