Title: Method for improving bonding strength of aluminum alloys during friction press
Inventor: LIN CHING-BIN
IPC: B23K20/12
Filed: 1998-10-08
Granted: 2001-06-23
Abstract: The present invention relates to a method for improving bonding strength of aluminum alloys during friction press. Two aluminum alloy connecting test rods, one of them has its connecting surface anodized or hard anodized, are fixed by a rotary multi-jaw chuck and a fixed chuck on a friction presser. A friction pressure is applied on the two aluminum alloy connecting test rods to allow them to closely contact with each other, and rotation is applied to allow them to rub against each other for a certain time. As soon as the rotation stops, a forging pressure should be applied for a certain time. Then, the required friction press is completed.

Title: Method and apparatus for producing a glass base material for an optical fiber
Inventor: NAKASHIMA YASUHIRO
IPC: G02B6/00
Filed: 1998-11-25
Granted: 2001-10-21
Abstract: A method and apparatus for producing a glass base material for an optical fiber. A material for an optical fiber and a reaction gas are jetted from a burner connected to a material line and a gas line toward a surface of a quartz substrate, in order to deposit a soot-like reaction product on the substrate at a predetermined position to thereby produce a glass base material for an optical fiber. Dry air is introduced into a reaction container in an amount of 2 to 30 times the amount of water vapor that is generated due to flame hydrolysis during the reaction. Therefore, it is possible to reliably solve the problem that the interior of the reaction container is excessively dried, with the result that soot generated through a reaction adheres to and aggregates on the wall surface of the reaction container due to static electricity, and the problem that the amount of water vapor becomes excessive and is condensed on the wall surface, with the result that soot strongly adheres to the wall surface, while the observation window or the like becomes fogged. Further, soot peeled off the wall surface is prevented from adhering to or melting into the side surface or base portion of a pre-form being pulled, so that the quality of products is improved, and stable operation becomes possible.

Title: Synchronization for cellular telecommunications network
Inventor: LUNDH PETER
IPC: H04W92/00
Filed: 1999-02-23
Granted: 2001-05-01
Abstract: Synchronization is effected in a cellular telecommunications network (20) between a master timing unit (60) located at control node (30) of the network and a slave timing unit (STU) located either at the control node or a controlled node, e.g., base station (22), of the network. In accomplishing the synchronization, one of the master timing unit or the slave timing unit serves as an initiating timing unit for transmitting a synchronization analysis command message including a first parameter (t1) to the other of the timing units which serves as a responding timing unit. In response, the responding timing unit sends a synchronization analysis response message which includes at least second parameter (t2) and preferably a third parameter (t3) to the initiating timing unit. The initiating unit uses e.g., parameters extracted from the synchronization analysis response message to determine a synchronization adjustment value for the slave timing unit. When the master timing unit is the initiating timing unit, the master timing unit transmits the synchronization adjustment value in a synchronization updating command message to the slave timing unit.
