    摘要： An inverter system having a semiconductor device, and a railway vehicle using this inverter, provide a more accurate determination of whether an abnormal heat generation from the inverter is associated with an error of the inverter system or is due to other causes, by use of a plurality of temperature detecting elements at a plurality of sites associated with the semiconductor device. An error detection section applies inputs from the temperature detecting elements, captures a trend of the differential value based on the plurality of temperature inputs using period sampling wherein an error associated with the semiconductor device, and not from some other condition such as outside environment temperature, is determined based on differences from, or a change in, the initial trend.

    摘要： The object of the invention is to provide an inverter system and vehicles using this inverter wherein accurate detection of the abnormal heat generation from the inverter is ensured, despite a large amount of noise signals, a substantial fluctuation in environmental temperature, or a change of cooling performances resulting from the environmental conditions. Based on the output value of an outside air temperature detecting means 150 and temperature calculation parameters inputted from outside the inverter system, the temperature calculation circuit 144B of an error detecting section 144 calculates the temperature Tcal where a temperature detecting means below semiconductor device 152 is installed. A calculation approximate line calculation circuit 144C works out the approximate curve of the difference between the theoretical temperature value and the real temperature value Treal detected by a temperature detecting means below semiconductor device 152, and captures the trend of the temperature difference, using a periodic sampling method, whereby a error determining circuit 144E determines an error, based on the difference from the initial trend obtained in advance or change of the trend.

    摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for indicating location status. A computing device can receive a query from a user device, a current time, and a location for the user device. The computing device identifies results responsive to the query, including one or more business results that are each associated with a business location and operating hours. The computing device can select a subset of the business results as open results based on the operating hours of the business results, the current time, and travel times from the device location to the respective business locations. Data can be provided for a search engine results page that designates the subset of the business results as open results.

    摘要： In a railway signalling system which transmits a control order to an on-board signalling system by a trackside signalling system, the on-board signalling system being mounted on a train running on a line and the control order being compliant with a signalling system of the line, the present invention allows the train to run through into lines with different signalling systems using a single on-board signalling system. When the train enters a line with a different signalling system from a current line, the on-board signalling system installs a train control application program compliant with the signalling system of the entering line. Then, the on-board signalling system executes the train control application program, allowing the train to be controlled on the entering line according to a control order created by the trackside signalling system of the entering line.
