IPC: H01M8/10
Filed: 2002-11-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a failure detection method of a fuel cell system capable of distinguishing the case where the state of the fuel cell system is in bad shape from the case where a cell voltage detection means has broken down, and vice versa.  <P>SOLUTION: The voltage of each cell constituting the fuel cell 1 is detected by the cell voltage detection means 8. When at least any of the detected voltages of the respective cells is below a predetermined value V1, the output current IFC of the fuel cell 1 is limited. When the fuel cell 1 is brought into an OCV state by the limitation of the output current IFC, and a voltage V below the predetermined value V1 is detected, it is determined to be a failure of the cell voltage detection means.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide an input device which has low power consumption and a long lifetime and is provided with a force sense feedback function capable of giving a natural operation feeling.  <P>SOLUTION: A driving voltage to a piezoelectric actuator is not supplied when waiting for depressing operation to a touch panel part, and the driving voltage is gradually raised in response to depressing operation at timing T401. At this time, a panel surface gradually goes up in accordance with bend of the piezoelectric actuator. The piezoelectric actuator is quickly bent in the reverse direction at timing T402 after prescribed time T1 to cause the panel surface to be displaced to the lowest position at timing T403, and it is kept in this position till timing T404 when the depression operation is terminated. The time T1 is made sufficiently longer than time T2, so that a strong force sense is given to a user when the panel surface displayed just after the depressing operation is displayed in the reverse direction thereafter. When the panel surface is displaced in the reverse direction, the extent of displacement can be increased because the bending direction of the piezoelectric actuator is inverted.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
