Provided are a data obtaining method, an inverter, and a rotating electric machine capable of managing the operation state of a device without complicating the configuration thereof. Therefore, the data obtaining method uses an inverter for controlling a synchronous electric motor, wherein a position/speed calculation unit of the inverter calculates an electric angle of the synchronous electric motor from the value of the current flowing between the synchronous electric motor and the inverter and obtains data for each electric angle by sampling internal data within the inverter, said internal data being used for controlling the synchronous electric motor in synchronization with the information of the electric angle.

A game apparatus has a touch panel for designating an arbitrary position within a screen on which a plurality of moving objects are arranged. A CPU repetitively detects the position designated via the touch panel, draws a line along the detected positions on the screen, every time that the detected position is in contact with any object within the screen, aligns the object on the line every time that the detected position is in contact with any object on the screen, moves the object aligned on the line to a trailing end direction of the line at a velocity Vwith the drawn line erasing from a leading end at a velocity V(&#x3e;V) and executes clearing processing in a case that an array of the objects on the line satisfies a matching condition with a goal condition array before the leading end of the line catches up with the object on the line.

In an inverter maintenance system, while an inverter of a user, a user support server of maker, and also, a portable telephone capable of accessing to a Web server are employed, such information required to maintain/manage the inverter is transferred/received by way of the portable telephone. Thus, various sorts of requests can be accepted by both the user support server and the Web server.

A system is provided to recover unutilized energy as electric power in hydraulic turbine power generation. The system includes a heat storage tank, a pump for pumping water from the heat storage tank and to air conditioning loads, a first water feed pipe connected between an outlet of the storage pump and the air conditioning loads, and a second water feed pipe for returning the water discharged from the air-conditioning loads. A hydraulic turbine driven generator is provided on a lower portion of the second water feed pipe at such a position as to recover the potential energy of the water discharged from the air conditioning loads.

Raw water such as polluted ground water can be recovered to clean water through the following processes. Firstly, oxidizing agent is added to raw water to disinfect bacteria, and then after suspended solid is removed from the water, ultraviolet rays are irradiated on the water so that organic chlorine compounds can be decomposed by active oxygen generated by the irradiation of ultraviolet rays. Finally, the residual oxidizing agent remaining in the treated water is reduced by activated carbon and catalytic resin. Further, the organic chlorine compound decomposition reaction is promoted at pH of 9 or below and in a temperature range of 15 to 30.degree. C.
