摘要： An Ethernet transmission apparatus having a quick protection and fair attribute as well as a corresponding method are disclosed. The apparatus comprises a sorter, MPLS processing module and a SDH processing module, wherein, the MPLS processing module includes a VC tag packaging unit, a multiplexing unit, a tag managing unit, a scheduler, an MPLS protective unit, an MPLS signaling unit and a Fair algorithm unit. The present invention sorts the Ethernet transactions and labels VC tags by the VC tag packaging unit so as to form a PW LSP. PW LSP with a plurality of identical source and target ends are multiplexed into a tunnel LSP. MPLS signaling unit counts the network nodes that LSP passes by and calculates a protective LSP. MPLS protective unit selects an active LSP or a protective LSP and enters the scheduler for queuing. The FAIR algorithm controls the allotment of the bandwidth so as to secure the fairness of the transactions.

摘要： A resolution adjustable game controller has a resolution button and a linear controller. When the resolution button is pushed, the resolution of the linear controller is changed to another resolution, and when the resolution button is released, the resolution restores. The resolution button is one of the buttons originally on the game controller or an additional button different from the original buttons on the game controller. The control circuit is a chip which is electrically connected to the resolution button for controlling the resolution. When the resolution button is pushed, the resolution button is triggered, when the resolution button is released, the trigger condition is also released.

摘要： Isotactic poly ((R)-lactic acid) or isotactic poly (S)-lactic acid are respectively prepared from (R,R)-lactide and (S,S)-lactide using a catalyst which has a zinc center or a magnesium center and two ligands where one of the ligands is a propagating group and the other of the ligands is not a propagating group. Heterotactic poly(lactic acid) is prepared from rac-lactide using a catalyst which has a zinc center and two ligands where one of the ligands is a propagating group and the other of the ligands is not a propagating group; heterotactic poly(lactic acid) is a novel composition. The catalyst with a magnesium center is a novel catalyst. Syndiotactic poly(lactic acid) is prepared from meso-lactide using a syndiotactic poly(lactic acid) effecting catalyst which has a zinc center and two ligands where one of the ligands is a propagating group and the other of the ligands is not a propagating group and the preferred catalyst contains as the ligand which is not a propagating group diiminate substituted with isopropyl substituted phenyl and the propagating group is isopropoxide. Atactic poly(lactic acid) of polydispersity ranging from 1.15 to 1.40 is prepared in less than 10 minutes by polymerizing rac-lactide in the presence of C1-C4 alcohol and a catalyst with a magnesium center and two ligands where one of the ligands is a propagating group and the other of the ligands is not a propagating group.
