摘要:
A ground surface as an image acquiring object is acquired by a synthetic aperture radar mounted on an artificial satellite at a usual time before occurrence of a disaster and thereby radar image data are obtained. After the occurrence of the disaster, an image of the ground surface as the image acquiring object is acquired within days shorter than the number of orbit returning days and by comparing this radar image data with the radar image data acquired at the usual time so as to try to early grasp a damaged situation. At a recovering and rebuilding time after the occurrence of the disaster, images of the image acquiring object are periodically acquired so as to prepare a recovering and rebuilding plan and prevent secondary disasters.

摘要:
In a radar image processing device and a radar image processing method which can accurately extract a change of a ground surface, a communication interface unit (10) obtains a plurality of radar image data of a same observation target obtained at different times and stores in a radar image storage unit (12), and a registration processor (14) reads the plurality of radar image data from the radar image storage unit (12) and registrates the radar image data with respect to each other. Then, a characteristic value calculating unit (18) calculates a plurality of characteristic values indicating a state of a ground surface which is the observation target based on the positioned radar image data. A change candidate region extracting unit (34) extracts change candidate regions for each of the characteristic values, and a judging unit (36) extracts a region of land cover change of the observation target from the change candidate regions using a threshold value, an extracting condition, and a judging function determined by a judgment method determining unit (24).

摘要:
This silicon wafer production process has a step of cutting a silicon wafer from a silicon single crystal ingot in a perfect region which includes a perfect region P free of agglomerates of interstitial-silicon-type point defects and agglomerates of vacancy-type point defects and/or a region R in which there is occurrence of ring-shaped oxidation induced stacking faults, and a step of performing rapid thermal annealing on the silicon wafer in a hydrogen atmosphere, an argon atmosphere or an atmosphere containing a mixed gas thereof.
摘要:
Disclosed are a control system and a control method for an automatic transmission, in which a judgment is made whether or not a range selector (31) has been switched to a reverse range during forward traveling of the vehicle. When it is determined that the range selector (31) has been switched to the reverse range during forward traveling of the vehicle, a judgment is made whether or not the vehicle speed is lower than a first vehicle speed and whether or not the period of time that has elapsed until switching from the forward to the reverse range is shorter than a predetermined judgment time. When the vehicle speed is lower than the first vehicle speed and the period of time that has elapsed until switching from the forward to the reverse range is shorter than the predetermined judgment time, a forward/backward changeover mechanism (4) is switched to a reverse mode. Otherwise, the switching of the forward/backward changeover mechanism (4) to the reverse mode is delayed.
摘要:
A protection structure for a surge absorbing element for protecting equipment such as communications lines from surges caused by lightning or the like which makes use of a surge absorbing element in parallel with the equipment to be protected and a low melting point metal wire in direct contact with the element and in series therewith. The structure protects the surge absorbing element or assembly from continuous overvoltage or overcurrent which may be generated by a short-circuit of an alternating electric current source and the like.
摘要:
A surge absorber including a surge absorbing element for protecting communication equipment from transient surges and a thermal response switch with an automatic restoration function connected in parallel with the surge absorbing element. The inventive surge absorber prevents abnormal and deleterious heating of the surge absorbing element when continuous overvoltages or overcurrents are applied to the surge absorber.
