摘要： Data on inspection, diagnosis, repair and operation histories are entered in a plant-maintenance apparatus for equipment that constitute a plant to be maintained. Failure-event tree breakdown is performed on failures to be expected for the equipment. Unreliability is predicted of at least one starting item in the failure-event tree breakdown. Unreliability of each item in the failure-event tree is calculated based on a failure unreliability function. Unreliability and a cost of recovery from each failure event in the failure-event tree are multiplied and results of the multiplication are accumulated in accordance with the tree breakdown to obtain a recovery cost. Preventive maintenance expenses are calculated for preventing failure events. Maintenance timing and technique are decided through comparison between the recovery cost and the preventive maintenance expenses.

摘要： The present invention provides a method of inspecting a target component part (e.g., valve casing) of an apparatus (e.g., steam control valve) included in a steam turbine system. When a time period in a range of 24 to 100 hours passes from the shutting-down of the turbine system, or before a temperature of an atmosphere surrounding the component part is lowered to 100° C., the width of the opening of the crack formed in the component part or a clearance relating to the component part is measured without disassembling the target component part and an enclosing member (e.g., valve casing) from the apparatus. As the measurement is performed when a thermal stress is induced in the component parts or when the temperature distribution is wide, the risk level of the crack or the clearance is determined accurately.

摘要： A magnetic disk includes two kinds of texture lines formed on a substrate rendered to texturing, one kind being formed over the entire substrate and parallel with a circumference of the substrate and the other kind being formed such that a line tangent to the other texture intersects a line tangent to the one texture at an angle of 3 to 9 degrees. The other texture lines are yielded by processing the substrate with a polishing tape rocking the substrate radially thereof, and satisfying the floating characteristic of a magnetic head as being floated in a low degree, the contact-start-stop characteristic, and the attraction characteristic.

摘要： In an axial-flow turbine, at least one of front and rear side contact surfaces of shrouds (3a or 3b) of blades (1a or 1b) with respect to the turbine rotational direction is formed at certain angle with respect to a radial line connecting the rotor center and the contact surface. The shroud (3a) of the blade (1a) of a first kind is formed in a trapezoidal shape converging radially outward in cross section taken in a plane perpendicular to the turbine axial direction, and the shroud (3b) of the blade (1b) of a second kind is formed in an inverted trapezoidal shape converging radially inward in the cross section. Further, half of an angle (2.alpha.) between the front and rear side contact surfaces of the shrouds (3a or 3b) is made smaller than a static frictional angle of the contact surface. Since the shroud contact surfaces of two adjacent blades can be kept in pressure contact with each other under all operating conditions, a large dynamic stress reduction and superior damping properties can be obtained without producing excessive initial stresses at the blade airfoil and blade dovetail attachment portion.
