Patent JP-2002525755-A (JP)
IPC: G06F17/00
Filed: 1999-09-22
Abstract: Reorganization of database tables is performed while the tables being reorganized are available for normal OLTP activity. A trigger is setup to record OLTP activity on a source table to be reorganized. The source table is momentarily locked to establish an SCN checkpoint and determine the location of data blocks allocated for the source table. A copy of the table is created (new table) and blocks untouched/modified since the timestamp are unloaded from the source table and inserted into the new table. Transactions occurring since the timestamp are performed on the new table until no more transactions since the timestamp remain in the trigger record. The new table is switched with the source table (renamed as the source table), and the original source table is dropped.

Patent JP-2002527968-A (JP)
IPC: H04R1/02
Filed: 1999-10-04
Abstract: An electroacoutic communications unit with a receiver transducer in a housing. The communications unit has accoustic connections both from the front side of the diaphragm of the transducer and from its rear side to the area inwardly of the face of the unit for engagement with a user's ear as well as to the area outwardly of this engagement face. These four acoustic connections constitute the four branches of an acoustic balance bridge with the transducer as a generator. This configuration is particularly expedient, as it is hereby possible to reduce the inner air volume in the communications unit behind the diaphragm of the transducer to a size which is without importance for the size of the telephone in practice. Furthermore, variations in the degree of tightness of the engagement of the communications unit with the user's ear will only influence the frequency characteristic to a very limited degree.
