Abstract: Structural design of cranial nerve degeneration contrast agent precursor, the cranial nerve degeneration contrast agent prepared using the cranial nerve degeneration contrast agent precursor can be used for positron radiation tomography to detect alpha-synuclein.

Abstract: Machining methods for machine tools where a workpiece can be manually moved by an operator or by automatic operation. A drawing file is displayed on a screen and machining is performed. An evaluation is performed to determine if the processed points of the workpiece match the desired processing coordinates within a tolerance range. Accordingly, the system is selectively activated to prevent processing at incorrect processing points or deviating from the tolerance range of the desired processing points. Processing yield rate is improved and all processing points are monitored by the system and displayed on a drawing file screen.

Abstract: A processing method of processing machine is disclosed. The operator may shift the work piece waited for processing by hand or operated in the automatic mode. A drawing file screen of a main screen may be used and the system of the processing machine may be applied to judge to know if the processing points of the work piece waited for processing and the processing coordinates wanted to process are in the tolerance range. Accordingly, the system of the processing machine is activate to process so as to prevent from processing at wrong processing points or deviating from the tolerance range of the processing points wanted to process. It may make sure that the processing yield rate is improved and further make sure that all processing points may truly be finished processing which is monitored by the system and displayed on the drawing file screen of the main screen.
