摘要:
A memory unit stores maps of predetermined determination threshold values for detection values detected by a hydrogen sensor according to an operating state of a fuel cell such as a difference in pressure between reaction gases at an anode and a cathode, supply pressure of the reaction gases, supply flow rate of the reaction gases and generated current of the fuel cell. A control unit obtains a predetermined determination threshold value from the memory unit based on the operating state of the fuel cell. Then, the detection value outputted from the hydrogen sensor and the determination threshold value obtained from the memory unit are compared, and in the event that the detection value is determined to exceed the determination threshold value, a predetermined protecting process is implemented for the fuel cell.

A light source unit and a spectrum analyzer are provided in which the influence of interference can be reduced under conditions where light is separated into spectral components. A spectrum analyzer 1 is equipped with a light source unit 2 for irradiating light onto sample A, a detector unit 3 for detecting the light reflected, scattered, or transmitted from the sample A, and a sample stage 4 on which a sample A is placed. A wide band light source 20 generates wide band light P1 such as supercontinuum light (SC light). Also, the light source unit 2 has an interference suppressing means for suppressing the interference of each wavelength component of the wide band light P1.

A correction characteristic determining device for (a) converting measured data, indicative of an emission condition of a liquid crystal panel, into brightness data of three primary colors by using a conversion matrix, and (b) determining the correction characteristic in accordance with a conversion result obtained by (a). The device may in certain example embodiments may set a target curve indicative of a relationship between a grey (or gray) scale value of an image signal and target output brightness. An adjustment parameter may be set by subtracting an actual brightness value from a lowest target output brightness in certain example embodiments. A relationship may be determined between a non-corrected grey scale value and a corrected grey scale value in accordance with the target curve that has been adjusted based at least on the adjustment parameter.

A failed manifold pressure sensor is identified in a control apparatus having two manifold pressure detecting systems as a failsafe. A first comparing unit outputs an abnormal signal when a difference ΔP between manifold pressures PMa and PMb detected respectively by two sensors is larger than a threshold value DP. A manifold pressure estimating unit estimates the manifold pressure from the engine revolution Ne, a throttle opening PLP, and an atmospheric pressure PAa. The difference calculating unit calculates a difference ΔPMb between the detected manifold pressure PMb and the estimated manifold pressure PMcal. The difference calculating unit calculates a difference ΔPMa between the detected manifold pressure PMa and the estimated manifold pressure PMcal. A second comparing unit compares the difference ΔPMa and the difference ΔPMb in response to the aforementioned abnormal signal. The failed manifold pressure sensor is specified according to which one of the difference ΔPMa and the difference ΔPMb is larger.
