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.

A sensor system includes a plurality of sensor bodies arranged aligned and adjacent to each other, each of said sensor bodies being connected to an electric cord including at least a signal line via a connector. Each connector has a power feed terminal, and a detachable fitting for electrically connecting the power feed terminals of the connectors is provided between the connectors. The power supplied to the connector of any of the sensor body through the power feed line in the electric cord is distributed to the power feed terminal of another sensor body through a row of connectors. By this configuration, the number of power feed lines for the overall system can be significantly reduced, and common bodies not distinguished for the main and sub bodies can be used as the sensor bodies, whereby the cost can be reduced and inventory management can be facilitated. Further, when any of the sensor bodies fails, it is possible to simply exchange the failed sensor body only, while maintaining the use of the electric cord that has been used.
摘要:
An apparatus is provided with a component feeding member for feeding electronic components having lead wires in a tape-bonded state, an insertion head for separating the electronic components fed from the feeding member from the tapes and inserting to holes of a board, and a fixing head facing the insertion head via the board for cutting and folding the lead wires of the inserted electronic component in the board thereby fixing the electronic component to the board. AC servo motors operating independently of each other are individually set in the insertion head and the fixing head, which are controlled by a device so as to be synchronous with each other.
摘要:
An apparatus for the processing and segmenting of a cover-forming laminate web or sheeting structure which is adapted to interconnect a plurality of containers, such as the base members of blister packages each of which is designed to contain a hydrophilic contact lens in a sterile aqueous solution. More specifically disclosed is an apparatus for the imprinting, perforating, slitting and cutting the laminated web structure such that the severed laminate segments constitute printed covering label for an array of such containers, and whereby the laminated web or sheeting segment may be severed along weakening or perforation lines so as to provide a separable packaging arrangement for individual of the containers which are subsequently adhered thereto.

The apparatus includes a light source section, a recognizing section, a moving device, and an operating section. The light source section is disposed transversely of a board so as to illuminate one side of the board. The recognizing section includes lenses, which are disposed transversely of the board so as to face the board from an opposite side relative to the light source section. The recognizing section also includes line image sensors disposed transversely of the board for receiving light rays from the lenses. The moving device is operable to move both the light source section and the recognizing section without changing the relative positions of these sections but moves them in such a way as to change their respective positions relative to the board. The operating section is operable to calculate image data for the entire board from image information obtained by the recognizing section and from position information obtained by the moving device.
