  • Patent number: 8688315
    Abstract: A first analyzing step is a step that conducts numerical analysis of a flow field but does not conduct numerical analysis of a temperature field in a state in which a motor rotor is rotating. The second analyzing step is a step that conducts numerical analysis of both the flow field and the temperature field after the first analyzing step ends. Accordingly, before numerical analysis of the flow field and numerical analysis of the temperature field are conducted together, numerical analysis is conducted first on the flow field in first analyzing step before it is conducted on the temperature field. As a result, compared with when the second analyzing step is executed from the beginning without conducting the first analyzing step, the calculation load of the numerical analysis on an electronic calculator can be reduced, which enables the time that it takes to conduct the numerical analysis to be shortened.

    Abstract: A cellular phone 1 includes displays 11 and 12, touch sensors 12 and 22 which receives an operation on the displays 11 and 12, an external speaker 308 which performs a notification action, and a CPU 100 which controls the displays 11, 12 and the external speaker 308. Here, the CPU 100 displays a snooze button B6 and a dismiss button B7, which are a target of the operation, on the display 11 or 21 during the notification action. If an operation on the snooze button B6 is a confirmation flick, the CPU 100 stops the notification action and furthermore resumes the notification action if standby time elapses after the notification action stops. In contrast, if an operation on the dismiss button B7 is a confirmation flick, the CPU 100 stops the notification action and furthermore cancels a setting of the notification action.

  • Patent number: 8339104
    Abstract: A battery system for a vehicle warms up a battery, which is mounted to charge and discharge. A charge/discharge unit is located closer to a battery set than an inverter unit is. When the battery set cannot produce a required output power because of its low temperature, a control unit controls the charge/discharge unit to charge and discharge and also controls a blower to deliver heat transfer medium, which receives heat generated from the charge/discharge unit, to the battery set, so that the battery set is warmed up to produce the required output power at earlier time.

  • Patent number: 8305043
    Abstract: In a voltage detecting apparatus, a voltage controlled oscillator, when an input voltage is applied thereto, outputs a signal with a logical value that is periodically inverted. A detector counts a number of logical inversion of the output signal from the voltage controlled oscillator over an interval between edges of pulses of a pulse signal to thereby generate, based on the counted number of logical inversion, digital data as a detected result of the input voltage. A determiner determines whether a reduction of a time required to detect the input voltage is higher in priority than an increase of a resolution of detection of the input voltage. A variably setting unit variably sets a frequency of the pulse signal based on a result of the determination of whether the reduction of the time required to detect the input voltage is higher in priority than the increase of the resolution of detection of the input voltage.
