Abstract
A failure is detected immediately and certainly, and continuation of processing in an unstable state is prevented. A first error detection code is generated from first information which is output as a result of execution of a predetermined program conducted by a first processor. A second error detection code is generated from second information which is output as a result of execution of the program conducted by a second processor which is configured so as to output the same computation result as that of the first processor. It is detected whether the first information is the same as the second information, and it is detected whether the first error detection code is the same as the second error detection code. Writing the first information or the second information into a main memory is controlled on the basis of a result of the detection.
A radio tomography imaging method according to the present invention includes: calculating a conversion function based on a transmission image picked up by using a radiation emitted from a first radiation source and a transmission image picked up by using a radiation emitted from a second radiation source; wherein a position of the second radiation source when the radiation has been emitted coincides with a position of the first radiation source when the radiation has been emitted, and one of the first and second radiation sources emits the radiation when the other emits the radiation, picking up a plurality of first reconfiguration transmission images and a plurality of second reconfiguration transmission images by using a plurality of first reconfiguration radiations and a plurality of second reconfiguration radiations simultaneously emitted from the first radiation source and the second radiation source; correcting the plurality of first reconfiguration transmission images and the plurality of second reconfiguration transmission images into a plurality of corrected transmission images based on the conversion function; and reconfiguring the plurality of corrected transmission images into three-dimensional data.
CT imaging is performed twice (S1101), which is set as the normal number of rotaions, and a sinogram is corrected (S1102) based on the sinogram obtained by performing CT imaging twice. Since the cycles of data variation caused by respiration are controlled so as not to overlap one another, usually the data variations caused by respiration are eliminated by performing CT imaging twice. However, depending on irregularity in the respiration cycle of the subject, data variation components sometimes overlap at the same angle in spite of the fact that the cycles of data variation caused by respiration are controlled so as not to overlap one another. Therefore, when data variation components remain overlapped at the same angle, CT imaging is performed one additional time (S1104) and the sinogram is corrected (S1102) using the sinogram obtained by performing the additional CT imaging.

In a control apparatus which transmits/receives data from a central processing unit via a serial transfer channel to a communication control unit, and groups/distributes data of input/output units from the communication control unit via a parallel transfer channel, the control apparatus initiates a diagnosing unit of the parallel transfer channel in response to an instruction issued from the central processing unit, and diagnosis the input/output units subsequent to the diagnosis of the transmission channel. Data input/output timing of the input/output unit is also instructed from the central processing unit, so that the central processing unit can suppress lowering of response speeds caused by the diagnoses, and can maintain the periodicity of the data input/output.

IMAGE DATA RECORDING METHOD, WORKING RESULT RECORDING METHOD USING IMAGE DATA, IMAGE DATA RECORDING DEVICE, AND WORKING RESULT RECORDING SYSTEM USING IMAGE DATA
An image data recording method is provided to carry out recording in a situation that an object is made to be truly consistent with its related data. In a working result recording method for acquiring a working record image of a recording subject product and its working contents, the recording subject product and its working record operator are accompanied with RFID tags (60: 60a and 60b) for recording inherent tag data, respectively. Thereafter, a time difference between a reading time of the tag data recorded on the RFID tag (60a) and an image data acquiring time of the recording subject product is compared with a prescribed time set in advance, so that the truth of the tag data is judged with respect to the working subject image data. Further, when the relationship between those data is judged to be true, the image data connected with the tag data are recorded as a working result. On the other hand, when it is judged to be wrong, the image data and the tag data are discarded.

New and useful method of building a boiler frame that significantly reduces the use of high load-lifting height crane and improves the operation efficiency despite of bad weather is disclosed. Multiple levels of steel supporting posts 20 that are established beforehand are linked together with their top portion by beams; and the 9th floor unit F9 is fixed to the posts at an intermediate floor position temporarily. Then suspension rods 42 suspended from lifting jacks 38 are connected to the 8th floor unit F8 and jack it up, while floor units made for lower than the 8th floor are connected on the ground to form a multi-floor unit. After connecting the multi-floor unit to the 9th floor unit F9, the temporally fixation is released, the multi-floor unit is lifted up, and each floor unit is permanently fixed to the designated floor position repeatedly and respectively.
A load balance is adjusted to be appropriate even if shared loads of lifting jacks are fluctuated from an initial setting state caused by cumulative errors of suspending rods. It is a load balance adjusting method of the lifting jack when a lifting module is jacked up by the plural lifting jacks via the suspending rods. The shared loads of the lifting jacks jacking up the respective suspending rods coupled to the lifting module are detected. A height of the lifting jack is adjusted when a fluctuation relative to a setting shared load stored in advance exceeds a prescribed range, to thereby adjust to be the setting shared load.
An interference with existing structures is prevented at a time of a lifting construction of a boiler module. When the boiler module is lifted from the ground by lifting jacks provided on a steel frame main-beam and made an install construction to the main-beam, lifting jacks enabled to move laterally on the main-beam are disposed at forward and backward thereof to suspend the boiler module. The suspended module is lifted up to the main-beam and installed while changing a suspending position between an interference preventing position with existing modules and a prescribed suspending position by alternately moving the forward and backward lifting jacks laterally.
A scaffold assembling of a large component for a boiler requiring inspection is not performed by a high-place work but assembled safely and in a short time. The scaffold is assembled to the large component for the boiler supported by a component supporting beam at the ground side before it is attached to a steel frame main-beam 16. Scaffold lifting/supporting beams interposing coil spaces of a superheater 14 are suspended on wires 36 lifted down from spaces of a ceiling tube wall 34 being a horizontal member of the superheater 14. The scaffold lifting/supporting beams 32 are lifted to raise little by lithe within the superheater, and scaffold components are assembled sequentially toward downward. After a required number of steps of scaffolds are assembled, the scaffold lifting/supporting beams 32 are coupled to the ceiling tube wall 34 to be supported. Finally, the superheater 14 is raised by a lifting means to install to the main-beam.
A computerized tomography device using an X-ray reconstructs a CT image of a sample and processes the CT image. Brown adipose candidate pixels are extracted based on a CT number of each pixel reconstructing the CT image. An erroneous pixel removal process is applied to the candidate pixels. In the erroneous pixel removal process, a boundary pixel removal process, a contraction and expansion process, or the like are applied. With this process, only the brown adipose pixels are extracted. An amount of brown adipose is determined from the brown adipose pixels and an evaluation value such as a brown adipose percentage is calculated based on the amount of brown adipose and amounts of other tissues.
