Filed: 2002-05-27
Abstract: <P>PROBLEM TO BE SOLVED: To provide a gas bearing with a simple structure capable of controlling thermal expansion of a rotary shaft and having stable running capability at high speed for a long time such as a hydrostatic bearing.  <P>SOLUTION: The bearing 12 is provided with a porous material such as a sintered body with stainless steel short fibers or the like. A water retaining portion 14 is arranged on a periphery of the bearing 12. When water is maintained in the water retaining portion 14, the water is supplied to a gap between the bearing 12 and a rotary shaft 11 through the bearing 12 made of a porous material by a capillary action. The water is heated by the rotary shaft 11 with a high temperature rotated at high speed, and becomes vapor. The rotary shaft 11 is supported by this vapor as lubricating fluid. Thermal expansion of the rotary shaft is controlled by vaporized water, and the rotation of the shaft becomes stable. The bearing is also operated as the hydrostatic bearing at the time of starting/stopping by providing a pressure device applying pressure onto the water in the water retaining portion 14.  <P>COPYRIGHT: (C)2004,JPO

IPC: H02M3/28
Filed: 2002-06-05
Abstract: PROBLEM TO BE SOLVED: To return energy stored in an inductance to a power supply through simple circuitry to make applicable switching semiconductor devices of low breakdown voltage. SOLUTION: When a switching semiconductor device 3 is off, energization is performed in the forward direction by a charge-storage diode 4 to store energy stored in an inductance means 2 in a voltage clamp capacitor 5.

Title: Optical burst signal routing system
Inventor: OGINO OSAO
IPC: H04B10/11
Filed: 2002-06-05
Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical burst signal routing system in which a variable length optical burst can be efficiently transferred while suppressing low transfer delay or discard in the middle of transfer.  <P>SOLUTION: Each optical node comprising an optical network holds information on a distance to an incoming optical node as a routing table for each incoming optical node when each out link is used. When an optical burst signal arrives (step S2), while referring to the routing table, the optical node selects an out link having an empty channel or empty buffer and a minimum distance to the incoming optical node (steps S3 and S4) and transfers the burst signal (step S9). In such a case, when the transfer distance such as the number of optical nodes to be passed by the optical burst signal or the transfer delay exceeds a threshold, the optical burst signal is discarded (steps S6, S7 and S8) and the congestion of optical burst signals in the optical network is avoided.  <P>COPYRIGHT: (C)2003,JPO
