Inventor: FUKAZAWA MASAKATA
IPC: H02G9/00
Filed: 1993-03-30
Abstract: PURPOSE:To facilitate large capacity transmission without restriction by the air temperature if necessary even if a heat loss is unavoidable collectively by a method wherein a heat exchanger is provided in the air entrance of a power cable and the entering air is cooled by utilizing a part of coolant in a cooling pipe. CONSTITUTION:A heat exchanger 21 is provided under a suction fan 8 for ventilation in the ventilation hole part 3 of a man-hole 2 and a heat exchange piping branched from a man-hole piping 7 is connected to the heat exchanger 21. The air is sucked through the suction fan 8 for ventilation periodically or in accordance with the necessity and the entering air is cooled by the heat exchanger 21 to prevent a tunnel temperature near the man-hole 2 from being elevated close to the atmospheric temperature. By keeping the tunnel temperature near the man-hole 2 at a temperature about the same as the temperature of the part other than the man-hole 2, therefore, the transmission capacity is not limited by the atmospheric temperature given by the ventilation hole part 3 of the man-hole 2, so that large capacity power transmission can be realized.

Abstract: PURPOSE:To facilitate observation with the lowering of noise during the X-ray irradiation by catching an endoscope in an X-ray image obtained with the irradiation of a part to be inspected from an X-ray irradiation part of an X-ray device when the X-ray device and an endoscope apparatus are observed with the same moni tor. CONSTITUTION:A subject is irradiated with X rays by an X-ray irradiation section 2 from above and an X-ray image is obtained at a roentgenography section 4 on the rear of the subject to be inputted into an X-ray device 3 and into an endoscope image controller 10. The image of the X-ray device 3 and the image of an endoscope apparatus are displayed on the same CRT tube. The position of the endoscope 1 is controlled so that the image of the endoscope 1 is caught in the X-ray image. In the irradiation with X rays, noise components are checked with a reduction circuit. This facilitates the location of an affected part with the endoscope thereby achieving easier observation of the affected part.

Title: Heat fixing device
Inventor: WASHIYAMA NARITATSU
IPC: G03G15/20
Filed: 1983-05-27
Abstract: PURPOSE:To improve the controlling accuracy of the surface temperature of a fixing roller without using any contact type temperature detecting element by installing a detecting means of the environmental temperature of the fixing roller and a control means which controls the surface temperature of the fixing roller to be maintained at a prescribed temperature. CONSTITUTION:At the time of standby, a set temperature T is maintained as shown by the curve B by actuating a surface temperature control device in accordance with a detected environmental temperature and turning on and off the lighting of a heater 3. When copying is continuously performed for (tau) time, the surface temperature of a fixing roller 1 drops in accordance with the curve C, but the surface temperature is restored to the set temperature T in accordance with the curve C'. The relation shown in the figure exists between the lighting time H of the heater required for restoring the surface temperature and the continuous copying time (tau). This relation also depends on the environmental temperature. Therefore, the environmental temperature and continuous copying time (tau) are detected and the heater 3 is continuously turned on for the H time by controlling the heater 3 by means 3 by means of the surface temperature control device. Therefore, the surface temperature of the fixing roller can be controlled highly accurately without using any contact type temperature detecting element.

Title: Picture reader
Inventor: HONMA TSUYOSHI
IPC: G06T1/00
Filed: 1988-04-18
Abstract: PURPOSE:To attain accurate and stable binarization processing by tracing a threshold level properly at all times to a dynamic fluctuation of an original picture, a character and a ground density and avoiding tracing the threshold level to a faulty density picture. CONSTITUTION:A threshold value deciding means C uses a black peak obtained from a black peak detection means B and an average value of the white peak level by plural main scanning lines obtained from a white peak detection means A and determines a threshold level for binarization for each main scanning line and gives the result to the binarizing means D. The black peak detection means B revises and stores it as a black peak value only when the picture signal having a value over the black peak value to be stored is inputted by a prescribed or designated picture element number consecutively. Thus, even if a dynamic change exists in the picture, character and ground density of the original, the threshold level of binarizing processing is traced and the threshold value of the binarizing processing is not traced to a faulty picture. Thus, the binarizing processing is attained accurately and stably.
