Title: Rotary vacuum pump and its manufacturing method
Inventor: OKAMURA TOMOAKI
IPC: F04D19/04
Filed: 2002-03-19
Abstract: <P>PROBLEM TO BE SOLVED: To use a high-temperature resistance material as a rotor material for expanding a usable temperature range to comply with the increase of an exhaust flow rate.  <P>SOLUTION: A rotor is arranged while a predetermined minute clearance is secured between a stationary wall on the casing side and it. When the rotor is turned at a high speed, air is evacuated by this rotary vacuum pump. In this manufacturing method for the rotary vacuum pump, an initial creep strain history progressing at a rate higher than that for steady creep strain is previously applied to the rotor formed of an Al-Fe group quenched aluminum alloy before assembly with the stationary wall. Then, the stationary wall, to which a reduced dimension equivalent to the initial creep strain is given previously, is combined with the rotor, and the predetermined minute clearance is secured.  <P>COPYRIGHT: (C)2004,JPO

Title: Recording medium, recording method, and recording apparatus
Inventor: NAKAMURA OSAMU
IPC: G11B20/12
Filed: 2002-03-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a higher degree of freedom to a data format recorded on a magnetic tape and to properly record data on the magnetic tape even when the S/N of the recorded data is deteriorated.  <P>SOLUTION: In recording data to be recorded with a different recording density on a magnetic tape, information (recording density related information) associated with the recording density is recorded in the data recorded on the magnetic tape. Thus, even when data with different recording densities are recorded on the same magnetic tape, the recording and reproduction can properly be managed by referencing the recording density related information. Further, the recording density is changed by switching at a drive side depending on the quality of the recording data. Thus, when data write is disabled due to a recording error, it is possible to record data without an error by selecting a lower recording density.  <P>COPYRIGHT: (C)2003,JPO
