Filed: 1984-03-30
Abstract: PURPOSE:To remarkably improve properties such as durability etc. of multi-layer cured build-up areas, by allowing a metal having good wear resistance and penetrability or an org. curing impregnant to penetrate into weld cracks caused after build-up welding. CONSTITUTION:When multi-layer cured build-up welding is conducted on a revolving roll 11, weld cracks 19 are developed on build-up beads 18 formed on the surface of the roll 11. While a truck 21 loaded with a metal having good wear resistance and penetrability or an org. curing impregnant 20 is automatically moved on a guide rail 13 from the back of a submerged arc welding machine 14, the impregnant 20 is allowed to penetrate through a nozzle 22 into the weld cracks, whereby the impregnant 20 is allowed to thoroughly penetrate into the weld cracks of the build-up beads 18 and the cracks are filled with the impregnant. Thus, there is no possibility that cracks will propagate from the build-up cracks to cause peeling of the build-up beads 18.

IPC: H01S3/038
Filed: 1987-03-19
Abstract: PURPOSE:To obtain preferable symmetry of laser output radiation intensity distribution by uniformly disposing electrodes mounted in a discharge tube with respect to laser radiation from a total laser discharge tube. CONSTITUTION:Electrodes 2a-2d mounted in a discharge tube are uniformly disposed with respect to laser radiation from a total laser discharge tube. That is, in case of a gas laser oscillator made of 4 discharge tubes, the electrodes 2a-2d are so disposed that the electrode 2b is displaced 45 deg. with respect to the center line of the electrode 2a of the discharge tube 1a, the electrode 2c is displaced 35 deg., the electrode 2d is displaced 35 deg., in discharge tubes 1a-1d, and they are eventually displaced 45 deg. at each discharge tube. Accordingly, an irregular discharge region 9 is not concentrated at a part with respect to the laser radiation but discharged substantially symmetrical with respect to a laser oscillation axis in term of the whole discharge tubes. Thus, a uniform discharge can be obtained with respect to the laser radiation through the whole discharge tube to obtain the laser output radiation having good axial symmetry and no directivity in working characteristic.

Title: Burner
Inventor: SAITOU TOSHIHIKO
IPC: F23D11/44
Filed: 1984-03-30
Abstract: PURPOSE:To obtain the titled burner capable of shortening the rise-up time of an evaporator without any remarkable change in the quantity of heat received by the evaporator with respect to the variation in the quantity of combustion by providing the evaporator in parallel to a main burner body in the vicinity of burner ports of the main burner body forming a Bunzen flame. CONSTITUTION:The fuel vaporized by an evaporator 3 is introduced from a vapor injection nozzle 11 into the main burner body 1 through a fuel vapor feed pipe 10 together with air. When the fuel is ejected from burner ports and is ignited, an inside flame 13 and an outside flame 14 of the Bunzen flame are formed. At this time, since the evaporator 3 is disposed in the vicinity of the burner ports, that is, a position close to the base portion of the flame in such a degree as not contacting therewith, the positional relationship between the flame base portion and the evaporator 3 does not vary even if the quantity of combustion varies, a substantially predetermined quantity of heat received can be obtained. In a case where the fuel quantity is decreased, the position of the flame becomes low as a whole. Hence, the temperature of the burner ports 2 rises up higher than the case of strong combustion, and therefore the quantity of heat received does not vary so much because the flame base portion is drawn near to the evaporator 3.

Title: Sound-insulating walls for oil-immersed electric appliance
Inventor: YOKOYAMA MIKIO
IPC: H01F27/12
Filed: 1979-05-22
Abstract: PURPOSE:To build sound-insulating walls of little sound penetration, by providing an iron plate of lower rigidity than an external wall plate of iron so that the former iron plate is located inside the latter and faces against it across a gap and an oil vessel of double structure is manufactured. CONSTITUTION:An internal wall 4 is made of an iron plate of low rigidity so that the internal wall faces an external wall 5 which covers a transformer tank 2. The internal wall is located at an appropriate distance from the external wall. An oil- tight enclosed oil vessel is thus manufactured. A sound absorber 8 is laid on the inside of the internal wall 4. The oil vessel and the transformer tank are connected to each other by flexible joints 3. Radiators 6, 6' are attached to the external wall 5. Insulating oil 7 whose temperature raised by heat transferred from a transformer 1 flows through the joints to the oil-tight oil vessel made of the sound-insulating walls. The heat of the insulating oil is radiated from the surface of the external wall and from the radiators. Since the insulating oil is located between the double sound- insulating walls, penetrative sounds are greatly damped. Because the heat is radiated from the surfaces of the sound-insulating walls, the number of the radiators can be reduced.
