摘要： A liquid sealing type body mount has a stopper provided in liquid chambers to function properly with high rigidity and also to improve the durability. An inner cylinder is fixed to either a body or a frame and an outer cylinder is fixed to the other. A rubber elastomer is provided between the inner and outer cylinders and defines two liquid chambers, opposed to each other with respect to the inner cylinder and an orifice passage for communicating both the liquid chambers with each other. Inside both the liquid chambers there is provided the stopper with a metal portion which protrudes in the radial direction from the inner cylinder and is embedded in a rubber portion formed integrally with the rubber elastomer. There is a slight gap between the stopper and the chamber wall surface or the stopper slightly comes into contact with the chamber wall surface.

摘要： A tape management method capable of easily using a file on a virtual tape from a plurality of programs in a system virtually emulating a magnetic tape apparatus by a disk apparatus. When a use request is generated from other program to a volume of a virtual tape used by one program, a host computer generates and uses a volume of a temporal virtual tape and can thus permit the use of the temporal tape volume from a plurality of programs without drastically changing the specification of an existing tape interface. The volume of the virtual tape temporarily generated is generated in a virtual tape management table and a virtual tape file uses a file of the same type.

摘要： A technology in which a magnetic disk apparatus executes data relocation involves the problems how to cope with new setup of file management and hardware failure and performance drop at the time in a data relocation. The invention provide a technology capable of executing data relocation without moving physical data position by a magnetic disk control apparatus when a disconnection operation of a logical volume is made, while keeping setup of an existing file management system. Therefore, the magnetic disk control apparatus is provided with means for keeping a file position information list inside a logical volume, executing optimal data reorganization in such a fashion as to eliminate fragmentation of the list and updating a physical/logical address mapping table. Reorganization of the logical file position is made without the data movement.

摘要： A liquid sealing type body mount has a vibrating coefficient at 15 Hz frequency of about 4N·s/mm, and a moving spring constant at about 100 Hz reduced to about 1000N/mm to provide vibration isolation. The liquid sealing type body mount comprises an inner cylinder fixed to one of a body and a frame on the support side, an outer cylinder fixed to the other of them, a rubber elastomer provided between the inner and outer cylinders, two liquid chambers, and an orifice passage communicating the liquid chambers with each other, in which the load of the body is input in the axial direction. End walls of both the liquid chambers are formed of a rubber film extending aslant and outward in the axial direction from the inner cylinder side toward the outer cylinder.
