摘要： PURPOSE:To evade the inconvenient processing by making an operator recognize the asynchronous states of two pieces of digital input. CONSTITUTION:In regard of the digital input supplied through a digital input terminal 1, the data are demodulated by a digital input circuit 3 and at the same time the synchronizing signal of a subframe is sampled. In the same way, the data are demodulated by a digital input circuit 4 and the synchronizing signal of a subframe is sampled in regard of the digital input supplied through a digital input terminal 2. These two sampled synchronizing signals are inputted to a synchronization/asynchronization deciding circuit 5 which decides whether both signals are included in a fixed range or not. If so, the synchronization is decided. If not, the asynchronization is decided respectively. The asynchronous state is shown on a display device 6. Therefore the digital input is forcibly inhibited or switched to another signal input system. Otherwise one of two pieces of digital input can be selected. Thus the inconvenient processing can be evaded.

摘要： PROBLEM TO BE SOLVED: To make judgeable the existence/absence of a target square object by performing recognition decision of a square placed obliquely and deciding the uniformity of luminance inside the square in an image recognizing device recognizing a prescribed square from an input video signal. SOLUTION: This device compares the length in a height direction of each lateral direction equally spaced coordinates of a binarization area with a prescribed set value and recognizes and judges the existence/absence of the target square object even when the square object is placed obliquely according to the value of variable. The device calculates the accumulated value or the means value of luminance levels for every pixel in the vertical direction every coordinates of a prescribed interval in the lateral direction in an outward form square binarization area and can recognize and judge the existence/absence of the target square object by judging whether the change of the accumulated value on the mean value in every lateral direction coordinates is within a preliminarily set prescribed numerical value.

摘要： PROBLEM TO BE SOLVED: To realize data credibility and efficient data access processing in good balance in a RAID system for recording video data.SOLUTION: A disk control unit 22 of a video processing device 1 specifies whether data stored in a second area in which second failure has occurred is video data or management data during restoration from double failure. When it is specified as video data, an error is returned to a data reading request. When a data writing request occurs, the second area is defined as an error return area in which new data is overwritten according to the request. When it is specified as management data, the same data as the data stored in the second area is read from another area to copy the data in the second area.

摘要： PROBLEM TO BE SOLVED: To suppress the variation in velocity distribution of exhaust gas to be introduced into a catalyst layer of an apparatus for treating the exhaust gas by using a catalyst. SOLUTION: The catalytic exhaust gas treatment apparatus is constituted to react a material to be treated and reactive gas by whirling the exhaust gas containing the material to be treated and the reactive gas and introducing the gases into the catalyst layer after regulating the flow thereof. As a flow regulating means for regulating the whirling flow of the exhaust gas and the reactive gas, the apparatus uses a sheet-like flow regulating plate 4 having a through-hole 4a near the center in such a manner that the whirling flow is once collected to the through-hole disposed near the center of the flow regulating plate and is then passed through the through-hole so that its flow path is expanded again and is introduced into the catalyst layer. The variation in the gas velocity of the exhaust gas flowing into the catalyst layer is thereby reduced and a desired decomposition rate is obtained. COPYRIGHT: (C)2005,JPO&NCIPI
