IPC: G06F9/44
Filed: 1992-09-14
Abstract: PURPOSE:To facilitate design, to reduce a memory capacity and to enable a designed system to perform the high-speed processing by suppressing the number of slots managed and maintained by an object. CONSTITUTION:The maintenance (management) of the slots stored in the object 5 is performed by a clone. That is, it is performed by defining the object as a parent, generating a new child object by inheritance and simultaneously inheriting data the like from the clone maintained by the parent object. The clone 10 is present semipermanently until the disappearance of the object. The object generates the new clone 10a from the clone 10 managed by itself and manages it (the addition of the slot and the deletion of the clone 10a, etc.,) Thus, by storing the slot required only temporarily in the clone 10a and deleting the clone 10a after the processing, the semipermanent continuance of the unrequired slot is cancelled.

Abstract: PURPOSE: To save time and labor for setting a hoisting accessory and to lengthen a service life of a sling by providing the center parts of two parallel side plates piercingly with hanging holes, fitting an annular winding drum being communicated with the hanging holes, and arranging pins in symmetric positions with respect to the winding drum, between both end parts of both side plates. CONSTITUTION: A sling R of a wire rope is wound by one round around a winding drum 3 between the center parts of both side plates 1, and both ends of the sling R are respectively passed through between pins 4 and auxiliary pins 6 and locked to both ends of a suspended load W. A hook H of a crane or the like is inserted in a hanging hole 2 for lifting operation. An automatic adjusting type hoisting accessory automatically moves into a position above a center-of-gravity position of the suspended load W, and the sling R is wound around the winding drum 3 and fixed abutting both pins 4 through collars 5 to lift the suspended load W.  Since the pins 4 at both end parts are laterally symmetrical with the winding drum 3 placed therebetween, a layout direction to the suspended load does not matter even if the suspended load W is unequal load, and since the sling R is curved in the same direction, a service life can be lengthened.
