    摘要： A method, an apparatus and a computer for data operation are provided. The method includes: determining, when writing data to a sector of a storage device, whether the sector belongs to an old block for a restore point of the storage device. If so, the method further includes: allocating a new block and writing the data into the new block; creating a table including an address of the old block, an address of the new block and a first identifier, wherein the first identifier has first identification elements corresponding to the sector in the old block and in the new block, respectively, and wherein each of the first identification elements has a first state indicating to read data from the old block during data restoration in the sector and a second state indicating to read data from the new block during data restoration in the sector; and pointing the address of the old block in an address index table for the restore point to the created table. Otherwise, the method further includes: allocating a new block and writing the data into the new block; and modifying the address of the old block in an address index table for the restore point into the address of the new block. With the present invention, the time required for operation on the sector for the restore point of the storage device can be saved, and the performance of the computer can be improved.

    摘要： A method of making a passenger conveyor handrail includes forming a drive member having a plurality of longitudinally spaced drive surfaces. The drive member has a longitudinal stiffness for maintaining a desired spacing between the drive surfaces. The drive member is inserted into a molding device. A gripping surface portion of the handrail is formed using the molding device such that the gripping surface portion and the drive member are secured together. Another method includes forming a belt drive member having a plurality of teeth that establish a plurality of longitudinally spaced drive surfaces. The belt has a longitudinal stiffness for maintaining a desired spacing between the drive surfaces. Each of the teeth extends across an entire width of the belt. The belt is secured to a gripping surface portion of the handrail.

    摘要： Making a passenger handrail (30) includes splicing together ends (58) of handrail stock. A disclosed device (50) includes mounting members (54), (56) for positioning the ends (58) of the handrail stock relative to each other before splicing them together. Example mounting members (54), (56) include position control members (80) having at least one tooth (82) for engaging a tooth (36) on a driven surface (34) of the handrail. A disclosed example includes a mover (62) having a threaded rod (66) that causes a follower (68) to move with the mounting member (54) for adjusting a position of the mounting member and the corresponding end (58) of the handrail stock within very stringent tolerance requirements.

    摘要： A method of designing a tool for forming a rotor blade including an airfoil portion includes generating a computer model of a rotor blade having an airfoil portion, and determining a curvature and radius of curvature at sections of the rotor blade. An inner and outer diameter of a circumferential forming portion of a tool operable to form the rotor blade may then be calculated. A method of designing a tool path for forming a rotor blade including an airfoil portion includes generating a computer model of a cylindrical tool operable to form a rotor blade including an airfoil portion and of a rotor having a plurality of the rotor blades. The computer models of the rotor and tool are used to generate a first and second tool motion corresponding to airfoil suction and pressure portions. A method of forming a rotor with integral blades is also disclosed.
