Patent TW-I249521-B (TW)
Title: Process of purifying and producing high purity aromatic polycarboxylic acids and derivatives thereof
Inventor: LIN TSONG-DAR VINCENT
IPC: C07C51/42
Filed: 1999-11-19
Granted: 2006-02-21
Abstract: The present invention provides a solvent extraction purification method for aromatic polycarboxylic acids or derivatives that meet or exceed polymer-grade specification. The method includes dissolving a crude aromatic polycarboxylic acid or derivative in a base compound; removing impurities and excessive base compound; and removing residual base compound while making purified product. The purification method removes not only the impurities from the crude acid or derivative, but also the residual base compound from finished product that otherwise will contaminate the product. The salt in the cake is converted to product by acid-substitution, thermal decomposition, or electrolysis. The method uses base-extraction solvents to extract base compound and impurities from the salt. The residual base compound in the recovered product is then removed by leaching, stripping, thermal agitating with electromagnetic waves, or evaporation with thermal decomposition. The purification method allows eliminating crystallizers for crystallization and equipment for drying and pneumatically carrying. Finally, the purification method is combined with the oxidation and solvent recovery in prior art to use only one set of process steps, instead of two, to produce aromatic polycarboxylic acids or derivatives.

Title: Real-time control of chemical-mechanical polishing processes using a shaft distortion measurement
Inventor: LI LEPING
IPC: B24B37/013
Filed: 2000-07-11
Granted: 2001-10-01
Abstract: A method and apparatus are described for detecting an endpoint of a film removal process in which a film is removed using a polishing apparatus having a polishing surface connected to a shaft. Deformation of the shaft, resulting from torque caused by friction on the polishing surface, is detected. This detection is performed using either a sensor mounted on the shaft, or by monitoring a phase difference between light signals reflected from two points on the shaft. A signal is generated in accordance with the deformation of the shaft. A change in the signal indicates a change in the torque, thereby indicating the endpoint of the film removal process. This arrangement permits real time and in-situ monitoring and control of the film removal process.

Title: Inter-frequency measurement and handover for wireless communications
Inventor: MUELLER WALTER
IPC: H04W36/18
Filed: 2000-08-31
Granted: 2003-09-21
Abstract: A telecommunications network performs an inter-frequency hard handover for a connection with a user equipment unit (UE) by switching either from a cell or a current active set of base stations on a first frequency to a virtual active set of base stations on another (new) frequency. The inter-frequency hard handover can be an inter-frequency handover within a same system, or an inter-system handover. The virtual active set of base stations is maintained at the user equipment unit (UE), and is updated in accordance with one of several updating implementations of the invention. In a first mode of the invention for implementing virtual active set updates, the network authorizes the user equipment unit (UE) to report to the network the occurrence of certain network-specified events which are acted upon by the network for communicating virtual active set update information to the user equipment unit (UE). In a second mode of the invention, the network authorizes the user equipment unit (UE) to perform an autonomous virtual active set update upon occurrence of certain network-specified events, with inter-frequency events being reported from the equipment unit (UE) to the network and the network issuing an inter-frequency handover command. Advantageously, events which trigger intra-frequency measurements can be reused for reporting inter-frequency measurements. In another of its aspects, the present invention provides the network with a quality estimate for a current active set as well as a quality estimate for the virtual active set. The quality estimate can be utilized in a context of a handover from one UTRAN frequency to another UTRAN frequency, or even in the context of an inter-system handover (e.g., a handover between a UTRAN system and a GSM system for example). The quality estimate can be utilized to trigger a change or switch of frequencies/systems. Certain thresholds employed in the quality estimate-utilizing handovers provide hysteresis protection.
