Title: Heat treatment of hydraulic turbine runner
Inventor: KANBE MAMORU
IPC: B23K26/352
Filed: 1987-12-18
Abstract: PURPOSE:To improve the metal fatigue resistance and wear resistance of a hydraulic turbine runner so that the runner can be used for a long period of time hardening the region of the runner where the runner comes into contact with flowing pressure flow by a laser beam, thereby imparting a residual compressive stress thereto. CONSTITUTION:A bucket 5 of the hydraulic turbine runner 8 such as Pelton turbine is made of a martensitic stainless cast steel and the curved surface 5a region near the lip part 5c of the bucket 5 is subjected to the heat treatment in such a manner that about 10-20kgf/mm<2> compressive stress remains therein in order to improve the metal fatigue resistance and sand and soil wear resistance by the impact of high- pressure water. A black coating such as graphite intended to absorb heat is coated on the curved surface 5a near the lip part 5c on a hollow side to be heat-treated and thereafter, the laser beam is successively projected thereon to heat said part to the hardening temp. or above. The hardening is effected by the self-cooling effect by the stop of the laser beam irradiation. The residual compressive stress and surface hardening are generated in the bucket by this heat treatment. The metal fatigue due to the high-pressure water and the wear by the sand and soil in the high-pressure water are thus decreased and the long time service is enabled.

IPC: G11B5/84
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To enable discriminating damage realistically by storing a second reference area value being smaller than the reference area value, storing a second reference light quantity value being larger than the reference light quantity value, comparing an area of a region formed by a defective point with the second reference area value, and comparing the maximum light quantity value in the defective point with the second reference light quantity value when the area value is larger than the second reference area value.

Next, the peak value is compared with threshold value being a second reference light quantity value previously stored in the reference value storing section 15 for discriminating defect, when the peak value is larger than the threshold value, discrimination that damage exists is outputted. Further, a threshold value previously stored is larger than a light quantity reference value used in defect candidate detection processing.

Title: Gas insulation device directly connected with transformer
Inventor: IIDA TATSUO
IPC: H01F27/04
Filed: 1987-12-21
Abstract: PURPOSE:To dispense with any special device for mounting-and-dismounting for reducing the total size of a transformer and gas insulation apparatus, by providing an expansion joint of the connecting section in the transformer at a position where it is mountable-and- dismountable and at the same time providing mounting-and-dismounting function inside the transformer. CONSTITUTION:A mounting-and-dismounting conductor 25 is tightened electrically and mechanically by bolts 32 to a conductor 26 on the left and to a connecting conductor 27 on the right. The bolts 32 can be tightened or removed by removing a shield 24 which is fixed to the mounting-and-dismounting conductor 25 with a bolt 33. After removing the mounting-and- dismounting conductor 25 and the connecting conductor 27 through a working manhole which the blank covers 34, 35 are removed, an expansion joint A23 is shortened with a stud 38 and a nut 39. As a result, a container B22, which has an insulating spacer 28 and the conductor 26, can be moved in the direction of an arrow Y1 until the inside of the container B22 is brought into contact with a shield 36. Since a transformer 1 and a gas insulation apparatus 6 are designed so that there is a space 37 between an adjacent conductor 31 and the insulation spacer 28, that is, between parts both protruding most, the transformer 1 and the gas insulation device 6 can be completely separated electrically and spatially by moving the container B22 in the direction of an arrow Y2.

Abstract: PURPOSE:To prolong the pot life of a magnetic coating compd. and to obtain a magnetic recording medium which exhibits good durability by incorporating a polyurethane resin having a heterocyclic amine structure which has the catalytic activity to the reaction of an polyisocyanate group and polar group in the molecule into a binder. CONSTITUTION:The polyurethane resin to be used as the binder of a magnetic layer has the heterocyclic amine structure which has the catalytic activity to the reaction of the polyisocyanate group and the polar group in the molecule. Said resin has also the function to greatly accelerate the crosslinking reaction of the polyisocyanate compd. by the catalytic effect of the heterocyclic amine structure part. The improvement in productivity and the reduction of an energy cost are, therefore, enabled by using such polyurethane resin. This polyurethane resin is advantageous in that the resin has no undesirable influence on lubricating agent components and that the pot life of the magnetic coating compd. contg. said resin and the low molecule weight polyisocyanate compd. is greatly prolonged. The wear resistance and eventually the durability of the magnetic layer are thereby greatly improved.
