A technology for preventing degradation of a hydrogen permeable metal layer in a fuel cell 210 is provided. A fuel cell system 200 including a fuel cell 210 with an anode which has the hydrogen permeable metal layer comprises a fuel cell controller 230 for controlling the operation status of the fuel cell system 200, a temperature parameter acquisition section for acquiring a temperature parameter of the hydrogen permeable metal layer, and a hydrogen permeable metal layer degradation prevention section which reduces the hydrogen partial pressure in an anode channel 212 for supplying fuel gas to the anode. If a temperature of the hydrogen permeable metal layer represented by the temperature parameter deviates from a specified temperature range, the fuel cell controller 230 cause the hydrogen permeable metal layer degradation prevention section to operate for preventing degradation of the hydrogen permeable metal layer.

A control device 7 obtains a reformed carbon quantity C supplied to a reform reaction flow channel 21 from a supplied fuel quantity Qf and also obtains a reformed water quantity S supplied to the reform reaction flow channel 21 from a generated power quantity W. Further, it obtains a oxygen consumed quantity consumed through power generation in a fuel cell 3 from the generated power quantity W, a supplied oxygen quantity to be supplied to a cathode flow channel 33 from a supplied cathode gas quantity Qc, and a reformed oxygen quantity O to be supplied to the reform reaction flow channel 21 based on a difference between the supplied oxygen quantity and the consumed oxygen quantity. By correcting a reformed carbon quantity C (delivery of a fuel pump 51) in accordance with the reformed oxygen quantity O, each of O/C and S/C is kept in a target value range.

According to this invention, when initialization of a storage medium such as a flash memory is erase of the data area, the processing can be stopped. When the processing is stopped, at least initialization of the management area has been completed, and processing using the storage medium can be executed. If erase processing is not stopped but proceeds to the end, no erase processing need be performed in writing new data, and high-speed write is promised. For this purpose, when complete formatting is designated, the management area of the file system is first initialized. Then, erase processing for the data area of the file system is executed by a predetermined block size. If it is determined that stop is designated during the data area erase processing, the processing ends, but the management area has already been initialized.
摘要:
A carbon monoxide concentration reducing apparatus that raises the internal temperature of a CO-selective oxidation unit carrying a selective oxidation catalyst in as short a time period as possible after the apparatus is started, and a driving method for the apparatus are disclosed. In addition to the selective oxidation catalyst, the CO-selective oxidation unit contains an oxidation catalyst. The oxidation catalyst is capable of facilitating oxidation of an oxidizable gas component of a hydrogen-rich gas, even at temperatures substantially equal to a normal room temperature. The oxidation catalyst is, for example, a platinum (Pt) catalyst. Even when the internal temperature of the CO-selective oxidation unit is substantially equal to a normal room temperature, the oxidizable gas component of the hydrogen-rich gas can be oxidized by oxygen contained in an oxidative gas, via the function of the Pt catalyst. Using heat produced by this oxidation, the temperature of the hydrogen-rich gas can be raised, so that the internal temperature of the CO-selective oxidation unit can be raised to a desired temperature.

A photoelectric device for use as a radiation thermometer capable of measuring the temperature of a target without being in contact therewith is provided. The photoelectric device can include a photovoltaic cell of germanium that is suitable for a radiation thermometer capable of measuring the temperature of a target between 200 degrees C. to 800 degrees C. The electrical output of the photovoltaic cell corresponding to the intensity of radiation is made independent of any change of the characteristic of the cell resulting from temperature.

A cyclic A/D converter which can reduce the number of reference voltages for D/A conversion is provided. The cyclic A/D converter (11) comprises a gain stage (15), an A/D converter circuit (17), a logic circuit (19), and a D/A converter circuit (21). In an operational action of the gain stage (15), an operational value (VOP) is generated by the use of an operational amplifier circuit (23) and capacitors (25, 27, 29). The gain stage (15) operates as receiving three kinds of voltage signal from the D/A converter circuit (21) by the switching of two kinds of voltage signal (VDA1, VDA2) to be applied to the capacitors (25, 27) in a switching circuit (31). That is, the D/A converter circuit (21) provides a voltage signal (VRH) to the capacitors (25, 27), in response to a value (D=2) of a digital signal (B0, B1), provides voltage signals (VRH, VRL) to the capacitors (25, 27), respectively, in response to a value (D=1) of the signal (B0, B1), and provides the voltage signal (VRL) to the capacitors (25, 27), in response to a value (D=0) of the signal (B0, B1).

In an image sensing apparatus having a zoom lens, a zoom ring that designates driving of the zoom ring at the time of image sensing, a power switch, and a zoom controller of the zoom lens that is capable of changing a driving speed of the zoom lens, it is determined whether or not operation of the zoom ring is performed in combination with predetermined operation of the power switch. In a case where the operation is performed in combination, the driving direction of the zoom lens designated by the zoom ring is detected, and driving of the zoom lens is continued in the detected driving direction during performance of the predetermined operation of the power switch irrespective of continuation or discontinuation of the zoom ring operation.
摘要:
A CDA processing section extracts an unused area of an information recording medium via a disc status management section and a drive control section. The CDA processing section divides the extracted unused areas by a division criteria value MAS, which allows continuous reproduction of a video and audio stream, and reserves areas having the size of the division criteria value MAS as CDAs. This enables continuous reproduction of AV data, and multiple data can be recorded simultaneously.
