摘要： PROBLEM TO BE SOLVED: To prevent the generation of sparks throughout the whole process of drilling work by providing a water supply way in the shaft center direction of a drill bit and a water jetting hole in the tip portion of shaft core and then supplying water from an external water source. SOLUTION: A water supply way 3 is provided inside a drill bit 1 along the rotating shaft center of the drill bit 1, and a water jetting hole 2 is provided near the tip in the shaft center direction. A water supply mechanism 5 for supplying water from the outside of the water supply way 3 is fitted to a coupling rod member 10 in a freely rotatable manner. A ring-shaped water space 23 for filling water between a water jacket member 20 and a coupling rod member 10 is formed, and a water supply hose 45 from the outside is connected to a joint portion 21. By making a configuration as stated above, the generation of sparks due to the impact between the drill bit 1 and an object to be drilled can be prevented, or generated sparks are shielded with water against combustible gases or liquids thereby preventing igilion from occurring.

摘要： PURPOSE:To achieve miniaturization and cost reduction of a heat exchanger by preheating a cooling medium with a heat exchange between discharge gas and the cooling medium by using a regenerative heat exchanger of switching time within a minute, so as to improve efficiency in a heat exchange. CONSTITUTION:Simultaneously with introducing discharge gas within a minute to a heat storage tank A, a cooling medium is introduced to switch switching valves 20, 24, 36, 40 and to place high temperature discharge gas from a generating part 14 in a heat storage tank B through a bypass line 22, and the gas, after heating a ceramic honeycomb of heat storage material, is discharged to the outside of a regenerative heat exchanger 12. On the other hand, the cooling media passes through a bypass line 32 to suppress a temaperature fluctuation in a temperature relaxing chamber 30, and after a time within a minute, the switching valves 20, 24, 36, 40 are instantaneously switched to introduce the discharge gas and cooling medium respectively to the heat storage tanks A, B. Thus by repeatedly switching the switching valves, a heat exchange between the discharge gas and cooling medium is efficiently performed to provide miniaturization capable, and setting up and economical efficiency can be improved.

摘要： PURPOSE:To provide sealing structure with high sealing effect without any deterioration of components of a solid electrolyte fuel cell by using a metallic gasket as a sealing material. CONSTITUTION:A cylindrical metallic gasket 18 formed by winding double layer nickel foils to a cylindrical gas introducing part 12 is inserted into a fixing hole installed in a supporter 14 made of a heat resistant alloy for fixing. When a cylindrical solid electrolyte fuel cell with this sealing structure is operated, part, in contact with air, of the gasket 18 expands by oxidation on temperature rising to form an oxide forming part 20, and a gas is completely sealed. When operation is stopped and the cell is cooled to room temperature, the oxide forming part 20 contracts and a gap may be produced in the sealing part, but when operation is resumed, air enters the sealing part from the gap and a non-oxidation part on the lower side of the oxide forming part 20 expands by oxidation on temperature rising to form a new oxide forming layer, and the gas is sealed again.

摘要： PROBLEM TO BE SOLVED: To obtain inexpensive illumination of an endoscope without increasing the outer diameter.
SOLUTION: When an object is picked up with a lens system 22 and a CCD imaging device 23, illumination is obtained from a small-sized white LED 26 by guiding the LED emission by using a transparent pipe 29. The small-sized white LED 26 is housed in a space in the periphery of a cable 24 connected to the CCD imaging device 23 in a camera case 25. Since the diameter of the cable 24 is smaller than the external size of the CCD imaging device 23, the small-sized white LED 26 can be housed. Since the small-sized white LED is not externally mounted to the camera case 25, the outer diameter as the endoscope 21 does increase. Further, since the light source is incorporated in the camera case 25, an optical fiber for guiding light from the outside is unnecessitated, so that the object to be picked up is inexpensively illuminated.

摘要： PROBLEM TO BE SOLVED: To allow a traveling body to satisfactorily travel along lines such as weld lines traveling to a prescribed direction on a three-dimensional traveling face. SOLUTION: In this method for controlling the traveling of a traveling body, detection information with weld lines 3 existing on a traveling face as a reference line is detected, and the traveling of a traveling body which is steered while adhered to the traveling face is controlled based on a traveling control command generated by a traveling control command generating means 7 based on the detected detection information. In this case, the inclination of a traveling body reference axis to the reference line is detected, and a differential traveling command is generated by using the detected inclination of the traveling body reference axis as differential information related with deviation in a position so that the inclination of the traveling body reference axis can be reduced. Thus, the traveling of the traveling body can be controlled.

In this case, the deviation in a position of the traveling body reference position in a reference line crossing direction with respect to the reference line is detected, and the inclination of the traveling body reference axis to the reference line is detected, and a first traveling control command to reduce the deviation in a position is generated based on the detected deviation in a position, and a second traveling control command to reduce the inclination of the traveling body reference axis is generated based on the detected inclination of the traveling body reference axis. Thus, the traveling of the traveling body can be controlled.

摘要： PROBLEM TO BE SOLVED: To provide a weld line position measuring device which is provided with a surface displacement data creating means that measures the position of the surface of a weld base material part in a direction inclining at an angle with respect to the weld line and the surface displacement at this position to create surface displacement data, and determines the center position of the weld line on the surface of the weld base material part from the displacement data. SOLUTION: The device comprises a surface displacement data correcting means 63 that corrects the surface displacement data z (x) to corrected displacement data z1 (x) with equal surface displacements at both end portions on the basis of the displacements of the surface of both ends portions of position x of the surface displacement data z (x), and a means 81 for determining the weld line position that determines the center position of the weld line based on the corrected displacement data z1 (x).
