    摘要: A method of manufacturing a steam turbine rotor which includes an ultra-high temperature side portion in which ultra-high temperature steam flows and a high temperature side portion in which high temperature steam flows, the manufacturing method including the steps of: preparing a first electrode having a chemical composition corresponding to a chemical composition of a heat resistant alloy making up the ultra-high temperature side portion and a second electrode having a chemical composition corresponding to a chemical composition of the high temperature side portion; tentatively joining together joints of the electrodes, with the joints of the electrodes made smaller in cross sectional area than other electrode portions; subjecting the tentatively joined first and second electrodes to an ESR process to obtain an ESR ingot and forging the ingot into a shape of a rotor to obtain a rotor forging; and heat-treating the rotor forging to obtain a rotor blank and manufacturing the steam turbine rotor from the rotor blank.

    摘要: An optical reflection sensor emits light and its reflection from a target object is received. A signal processor carries out a measurement on the received reflected light such as the distance to the target object each time the reflected light is received. Repeatability of measured values is calculated and displayed on a display device incorporated into the housing of the sensor. The display device may have two display areas such that the calculated repeatability and the measured value can be displayed simultaneously. The calculated repeatability may be compared with a specified threshold value, with the result of the comparison displayed. The housing may also incorporate an input device through which a required level of accuracy may be set.
