摘要： PURPOSE: To manufacture an alloy with superior stress corrosion cracking resistance by adding a specified percentage each of Cr, Mo, Al, Ti and Nb to Ni and providing γ' or γ" phase to an austenite-phase matrix.
CONSTITUTION: An alloy consisting of, by wt., 15W25% Cr, 1W8% Mo, 0.4W2% Al, 0.7W3% Ti, 0.7W4.5% Nb and the balance Ni is prepared, and γ' and/or γ" phase is provided to an austenite-phase matrix. Al, Ti and Nb are preferably added in the range of 3.5%≤2Al+Ti+1/2Nb≤5.5%. The preferred C content is about 0.02W0.06%. It is preferable to add Cr, Mo, Ti and Nb to the alloy as ferroalloys, so the Fe content is adjusted to ≤40%, and the Ni content is ≥40%.

摘要： PURPOSE:To decrease remarkably the teaching time by the operator by deciding the torch holding attitude from the direction of a torch decided by a CAD data and the direction of a turning shaft taking the limitation of mechanism into account. CONSTITUTION:A normal vector at a welding point P is obtained as a vector OP tying a center point O of a radius and the welding point P. Although the vector OP is described to a work coordinate system R2, a transforming matrix OP from a reference coordinate system Ro to the Rw is multiplied by describing it as a vector to the reference coordinate system Ro. Thus, the direction of the torch to the coordinate system Ro is decided and the X axis of the torch coordinate system T is decided. Since the Z axis in a Z axis direction deciding T coordinate system satisfies two conditions that the Z axis in a plane perpendicular to the X axis due to the limitation of mechanism of the robot and in a plane Q perpendicular to the running axis due to the limitation of mechanism, the direction of the Z axis is decided as a cross line of planes satisfying the conditions. The direction of the Y axis is decided definitely when the direction of the X and Z axes is decided.

摘要： PURPOSE:To prevent stress corrosion cracking in a rotor including a wheel secured on a shaft by a key, by embedding a material, whose corrosion potential is lower than that of the wheel, in at least one of the shaft, the wheel and the key so that a part of the material is exposed. CONSTITUTION:A wheel 4 is fitted on a rotor shaft 3. A key 2 is inserted into keyways 1, 1' provided in the shaft 3 and the wheel 4, thereby securing the wheel 4 on the shaft 3. Grooves 6, 6' are previously made in the portions of the key 2 which correspond to the shaft 3 and the wheel 4. An anticorrosive material 7, 7', whose corrosion potential is lower than that of at least the wheel 4, is embedded in the grooves 6, 6'. zince, aluminum, magnesium or the like is used as the anticorrosive material 7, 7' when the wheel 4 is made of Ni-Cr-Mo-V steel. Corrosion is thus prevented on the surface of the keyway 1' of the wheel 4 of a steam turbine rotor.

摘要： PURPOSE:To make a device small in size, and to reduce its cost by stratifying a product inspecting device to a small-sized computer part and plural tester parts provided with a microcomputer. CONSTITUTION:A product inspecting device 20 consists of a product inspecting device upper layer part 700 and a lower layer part 750, and they are connected through a floppy disk 710. This upper layer part 700 is constituted of an M/T driving device 701, a small-sized computer 702, etc., converts a test pattern data in an M/T 300 to a group of appropriate test items, and stores it in said floppy disk 710. Also, based on these data, an inspecting schedule, etc. can be made. Said lower layer part 750 is constituted of a microcomputer 752, etc., and by using these plural lower layer parts 750, plural control panel products 500 are inspected simultaneously. This inspection is executed by setting the floppy disk 710 to a floppy disk driving device 751.

摘要： PURPOSE:To reduce an error of an output pattern corresponding to a test pattern, and also to save an energy by using an electronic computer for an inspection of a design result of a control panel and an inspection of a product, and unifying the inspection of a design including an object to be controlled and the inspection of a product. CONSTITUTION:At the time point when a design is completed, a function of a control panel and a controlled system is inputted to an electronic computer of a design result inspecting device 100, and a motion of the control panel and the controlled system is simulated in the electronic computer. In case when there is no problem in its result, a test pattern and an output pattern required for a product inspection are saved in a magnetic tape 300. After a manufacture of the control panel is completed, a product inspecting device 200 combines a tester using a microcomputer and a product, gives the test pattern of the tape 300 to the product, and inspects automatically whether an output conforms with the output pattern in the tape 300 or not. In this way, a design error is reduced, and also an inspecting person and a time can be curtailed.
