Title: Cock with insertion type pipe joint
Inventor: KOU KIKA
IPC: F16L19/00
Filed: 1989-09-26
Abstract: PURPOSE: To make a cock with a pipe joint usable in a place hindered from repair work, with high reliability without a fluid leak by composing the cock with the pipe joint by a combination of a joint body of the cock with the joint, an annular recessed groove of a sleeve nut, and metallic material fittingly mounted with an O-ring or a seal ring formed of metallic material or synthetic resin material. CONSTITUTION: When a sleeve nut 4 is screwed by thread-fastening its internal thread 4a to an external thread 3a of a joint body 3 of a cock K with a bell- and-spigot pipe joint, the left half of the outer periphery 5b of a seal ring 5 comes in pressure contact with a nut side annular recessed groove 4d of a sleeve nut 4, and moreover a body side annular recessed groove 3b and the nut side annular recessed groove 4d are made into an integral combined semi- annular recessed groove R which comes in strong pressure contact with the outer periphery 5b of the seal ring 5. This causes the elastic deformation of the seal ring 5, and the seal ring 5 adheres strongly to the outer peripheral surface of a pipe 1 to form a watertight area.  At this time, the part, coming in contact with the pipe 1, of an O-ring 6 fittingly mounted in an annular inner groove 5c of the seal ring 5 bites into the pipe 1 to adhere to the pipe 1.

Title: Cache nullification processing system
Inventor: KAMIYA YASUAKI
IPC: G06F12/08
Filed: 1988-10-05
Abstract: PURPOSE:To prevent registered block data from being deleted wastefully and to accelerate performance by providing identification information to separate block data with different (n) kinds of meaning in unit of block data, and performing a nullification processing selectively on the information classified by every kind. CONSTITUTION:An identification information storage means 2 stores the information to identify block data with different (n) kinds of meaning in a cache memory 1 when plural pieces of block data are registered. An identification information readout register 9 receives the identification information corresponding to the block data read out from the identification information storage means 2 by a read address register 4, and nullification instructing registers 10 and 11 issue instructions to nullify the block data registered on the cache memory 1 individually. In such a way, it is possible to prevent the nullification processing from being applied on all block data, and to accelerate the performance.
