Title: All-fiber chirped pulse amplication systems
Inventor: FERMANN MARTIN E
IPC: H01S3/00
Filed: 2005-03-14
Abstract: By compensating polarization mode-dispersion as well chromatic dispersion in photonic crystal fiber pulse compressors, high pulse energies can be obtained from all-fiber chirped pulse amplification systems. By inducing third-order dispersion in fiber amplifiers via self-phase modulation, the third-order chromatic dispersion from bulk grating pulse compressors can be compensated and the pulse quality of hybrid fiber/bulk chirped pulse amplification systems can be improved. Finally, by amplifying positively chirped pulses in negative dispersion fiber amplifiers, low noise wavelength tunable seed source via anti-Stokes frequency shifting can be obtained.

Title: Dynamic-pressure bearing device, and bearing member manufacturing method
Inventor: HORI MASAHARU
IPC: F16C17/10
Filed: 2007-11-02
Abstract: A shaping pin (23) is formed to have a sectional shape, in which it contacts at two points (as indicated by P') with a virtual cylinder face (C'). As a result, a fixing hole (21b1) has its undercut reduced or eliminated, so that a mold can be easily worked.Moreover, a corner portion (21d) between a cylinder face (21c) and the fixing hole (21b1) is made blunt, so that the mold becomes hard to deform/break. Thus, the mold manufacturing cost can be lowered to reduce the cost for a bearing device. ® KIPO & WIPO 2009
