  • Patent number: 11868367
    Abstract: An information processing apparatus and method mitigate a processing delay of a system in a switched backup environment when the system is switched from a main environment to the backup environment in a hybrid cloud. A remote copy processing apparatus in the hybrid cloud has: a data access frequency management unit and a data access locality management unit that acquire and manage an access frequency and access locality regarding the access frequency from a host(s) in a public cloud to each pieces of data stored in a storage apparatus; a copy data judgment unit that judges object data of remote copy processing on the basis of a priority, the access frequency, and the access locality of the system; and a data copy execution unit that issues an instruction to the storage apparatus to start executing the remote copy processing on the object data.

  • Patent number: 5004497
    Abstract: A friction material containing 0.85 to 30% by weight of carbon fibers and 2 to 20% by weight of aramid fibers for use as brake pads, brake linings, clutch facings and other mechanical component parts which are subjected to severe frictional contact with other mechanical component parts. The aramid fibers preferably consist of para-aramid fibers and/or a combination of chopped aramid fibers and fibrillar aramide fibers. There is a certain preferred range for the ratio between the aramid fiber content and the carbon fiber content. This friction material offers advantages in a high-temperature stability of the coefficient of friction, a favorable wear property, freedom from sticking and uneven wears, and superior anti-fade properties.

  • Patent number: 4926978
    Abstract: Improved friction pads for use with disc brake. The pad has a central main portion and a peripheral portion which are formed of different matrices having different compositions. The matrix of the central main portion contains a hard substance or substances having a specified range of hardness whereas the matrix of the peripheral portion does not contain such hard substances or contains in only a limited smaller amount than the central main portion. This prevents the brake disc from wearing due to friction with the pad and thus avoids uneven abrasion of the brake disc.
