  • Publication number: 20120215809
    Abstract: A user registers information in searcher information storage in advance. Database creators register provision conditions of information in provision condition storage as a rule for defining information granularity. When a query request is received from a user terminal, a search request is sent to each database. Query results from the each database are acquired, and information to be provided into a form at an appropriate information granularity is sent to the user terminal. A third party may register disclosure restriction information. In this manner, a search mediation system capable of controlling information to be disclosed according to the searcher who wants to access to the information is provided.

  • Patent number: 6343792
    Abstract: A shaft seal having a high abrasion resistance is disclosed, by which the leakage of the gas from the high-pressure side to the low-pressure side can be reduced. In the shaft seal, flexible leaves are multi-layered to form a ring shape. The shaft seal is mainly arranged around the rotation shaft of a gas turbine or the like. The relevant turbine comprises a casing, a compressor, a rotation shaft, moving blades attached to the rotation shaft, and stationary blades attached to the casing in a manner such that the stationary blades face the moving blades, wherein the shaft seals are provided between a plurality of stationary blades and the rotation shaft wherein the leaves of each shaft seal contact the rotation shaft. Under the rated operating conditions, the top ends of the leaves slightly separate from the surface of the rotation shaft due to the dynamic pressure generated by the rotation of the rotation shaft.
