摘要： PROBLEM TO BE SOLVED: To enable auto identification of a fuel top face number of a fuel aggregate by detecting a corner of a number engraved face from an image as a feature point and setting a character region at a relative point from the feature point with characters having the same orientation being as a group. SOLUTION: In a character region setting device 3, an engraved character image fetching unit 10 fetches an image from a underwater camera 2, and an engraved face corner extraction unit 11 converts image data into a binary image and extracts a corner part of the fuel top face number engraved face as a characteristic point. An engraved character grouping unit 12 sets a character region at a relative position from the feature point with the engraved characters having the same orientation being a group, and a character enhancement device enhances an image character contrast. A character cutting device 4 cuts engraved characters in the character region every one character, a neural network type character candidate detector 5 sets a character feature quantity extraction window, and a character recognition device 6 recognizes the character. A character storage device 7 stores the recognition result and outputs it as a fuel aggregate number to a monitor 8.

摘要： PURPOSE:To provide a method and apparatus for measuring the water level reliably and simply based on the image from a water gauge while eliminating erroneous recognition caused by the shadow. CONSTITUTION:The image of a water gauge 1 for measuring the level of a liquid 10 with the eye is picked up by means of an ITV camera 2. The image is then converted through means 31 into a gray image and the gray level thereof is accumulated in the horizontal direction through means 32. The border position where the gray level varies significantly is then detected based on a histogram representing the horizontal gray level in the vertical direction. When the variation exceeds a threshold value, the water level is determined based on the border position in a predetermined direction (downward) and displayed on the screen of a monitor 4 so that it can be discriminated from the image of the water gauge 1.

摘要： PURPOSE:To provide a mobile monitor applicable to a high radiation region by employing high radiation resistant insulating material and holder material for the feeder trolley wire and the communication feeder wires built in a traveling rail. CONSTITUTION:A truck 1 traveling on a rail 100 is provided with a current collector for feeding power from a feeder trolley wire 22 to the monitor body, and an antenna 11 for conducting communication with a communication feeder wire 20 by microradio system. The insulating material 23 for the trolley wire 22, the trolley wire holder 202, and the insulating material for the communication feeder wire 20 employ not a polymeric material but a high radiation resistant material. When a ceramic material is employed for the insulating material and holder 201 of the feeder wire 20, the conductor of the feeder wire 20 is secured to the rail 100 through the insulating material and the holder by means of bolts.

摘要： PURPOSE:To accurately detect abnormality in both of an instrument of which fluctuation of surface temperature of the body due to the load fluctuation is small and an instrument of which the fluctuation is great during the normal driving by comparing relative intensity distributions of intensities of infrared radiation which are detected during the normal driving and during the monitoring thereof. CONSTITUTION:Intensity of infrared radiation from a surface of an instrument at the time when a motor 10 to be monitored is normally driven is taken to an image-inputting section 30 by means of an infrared radiation camera 20 to be stored into a normal time heat image memory section 50 via an image data transmitting exchange section 40. When the monitoring of the instrument is started, the image data is transmitted to a monitoring time heat image memory section 60 via the exchange section 40 to be stored in accordance with the instruction from an operator instruction input section 90. A two-dimensional relative coefficient operation section 70 fetches the heat image data in the normal time and monitoring time to execute the two-dimensional relative operation in accordance with a control signal from a monitoring control operation section 80. The resultant two-dimensional relative coefficient is supplied to the operation section 80 to calculate an abnormality degree of the instrument so that whether the instrument is abnormal or not is judged and the judged result is displayed 95.

摘要： PURPOSE:To provide an air-conditioning device which makes it possible to suppress changes in the cycle arising from a change in the piping length and satisfactory keep the comfortableness. CONSTITUTION:A throttle valve 6 controls the flow rate at which the liquid produced by liquefaction at an indoor heat exchanger 5 is sent to an outdoor heat exchanger 4. A controller detects the dynamic behavior of the cycle by using a discharged-gas temperature sensor, a room-temperature sensor, and an outdoor-air temperature sensor. On the basis of the detection signals the controller calculates the piping length, the overall length of the piping. The controller controls the throttle valve 6 in accordance with the calculated piping length. This method enables providing an air-conditioning device which can be operated with the cycle in the optimal state even when the piping length changes.

摘要： PURPOSE:To visually evaluate an analyzing process and an analytic result by visually constituting a refrigerating cycle and analyzing the cycle. CONSTITUTION:Components required for cycle constitution are selected from a component box, arranged in a work area 121, and piped 122. The attributes of the respective components are defined 123 and the start point and direction of the analysis are determined 123. A measuring instrument is arranged 132 so as to display the process of the analysis and the analysis is taken 112. Then the analytic result is displayed 133 on the measuring instrument once the respective components are analyzed. At this time, the operation state of the analysis is also displayed 131. Thus, the freezing cycle is visually constituted and then the cycle can be analyzed. Further, the analysis can be evaluated even at its halfway point.
