A low profile flat printed circuit connector has a plurality of terminals supported along a support bar. The terminals are spaced apart from each other and extend lengthwise in a connector housing. The terminals have body portions that engage the support bar and body portions that extend forwardly thereof. Contact portions are joined to the body portions and extend rearwardly and terminate in free ends so that they form a series of cantilevered contacts.

A damper mounting structure is provided with a top buffer member and a bottom buffer member. The bottom buffer member has a protruding section that protrudes with an outer diameter smaller than the outer diameter of the bottom buffer member. The damper mounting structure mates with the protruding section and is anchored to a vehicle body panel, and is provided with a collar formed at substantially the same height as the height of the protruding section. The corner of an opening formed on the vehicle body panel, which comes into contact with the top buffer member, is chamfered.

A start-up method for a fuel cell system that includes a fuel cell that carries out power generation by the electrochemical reaction between a fuel gas and the oxygen gas in the air; a fuel gas discharge path and a fuel gas supply path that are connected to the fuel cell; a fuel gas circulation path in which the fuel gas discharge path merges with the fuel gas supply path; and a purge valve provided on the fuel gas circulation path in order to discharge the circulating fuel gas from the fuel gas circulation path. The method includes the steps of opening the purge valve at the same time that the fuel gas is supplied to the fuel cell and replacing the nitrogen gas that originates in the air and is present in the fuel gas circulation path by fuel gas; and closing the purge valve after the nitrogen gas in the fuel gas circulation path has been replaced by the fuel gas.

A fire alarm system, determining existence or nonexistence of a fire by using an ultrasound wave, comprises a sound wave generator and a sound wave detector to detect sound waves propagated through two propagation paths having different lengths each other. The system comprises a calculation means for calculating a pressure ratio between a first sound pressure, which is a sound pressure of a sound wave propagated through a first propagation path, and a second sound pressure, which is a sound pressure of a sound wave propagated through a second propagation path, and a smoke density estimator. The smoke density estimator calculates a change ratio between the pressure ratio calculated by the calculation means and a predetermined standard pressure ratio, and determines a smoke density from the change ratio based on a predetermined relational expression describing the relation between the change ratio and the smoke density, and determines existence of a fire when the smoke density exceeds a predetermined threshold.

Fuel supply station information distributing system includes at least one vehicle, an information distributing server and at least one station, which are interconnected through communication line networks. The information distributing server transmits at every given time a request-to-send for vehicle information to the vehicles as well as a request-to-send for station information to the stations. The information distributing server then creates a fuel supply station information associating for each vehicle based on the vehicle information received from the vehicle and the station information received from the stations, and distributes it to the vehicle. When the vehicle receives the fuel supply station information from the information distributing server, it is displayed on the car navigation screen for notifying the driver.
