    摘要： A gas-fired engine that supplies high-pressure liquefied gas (e.g., LNG) as fuel by a reciprocating pump. A gas fuel supply device includes: a reciprocating pump driven by a hydraulic motor to boost an introduced liquefied gas pressure to a desired pressure and discharge the liquefied gas; a hydraulic oil introduction line that introduces a portion of high-pressure hydraulic oil from a hydraulic oil line and supplies the high-pressure hydraulic oil to the hydraulic motor; a hydraulic oil return line that returns the high-pressure hydraulic oil to the hydraulic oil line; a heating unit that heats and gasifies the boosted liquefied gas; a control section that adjusts a rotational speed of the hydraulic motor to maintain constant a gas fuel outlet pressure of the heating unit; and an engine inlet gas pressure-reducing valve that regulates a gas fuel pressure injected into a combustion chamber.

    摘要： A clock test apparatus connected to a GPS receiver mounted in a moving body has a frequency counter which counts clocks output from a clock generator incorporated in the GPS receiver for a predetermined period of time. In this manner, a clock frequency is detected and supplied to a clock error identification section. The clock error identification section calculates a short-term stability from the clock frequency, and further calculates a clock error on the basis of the short-term stability. The clock error data is supplied to a dynamics simulator. The dynamics simulator simulates circuit dynamics of the GPS receiver, and models error in the velocity of the moving body relative to a satellite, which results from the clock error, on the basis of the clock error data, thereby analyzing the performance of the GPS receiver.

    摘要： In a broadcasting receiver, to quickly switch channels of the received multiplexed broadcasting signals at a high response speed to improve the convenience for a viewer, when broadcasting signals of a plurality of channels are to be code-division-multiplexed and broadcasted from a ground broadcasting station (BC1, BC2) to a broadcasting receiver (MS) in a service area via a geostationary satellite (SAT), the broadcasting signals are multiplexed and transmitted after matching the spreading code phase between the channels in the ground broadcasting station (BC1, BC2). Alternatively, the spreading code phase difference between the channels of a CDM broadcasting signal arriving from the ground broadcasting station (BC1, BC2) is detected in the geostationary satellite (SAT), and the broadcasting signal is transmitted to the broadcasting receiver (MS) after matching the spreading code phase between the channels on the basis of the detection result.
