An infusion or injection solution of Levodopa containing at least 10 mgmL of Levodopa, or at least 5 mgmL of Levodopa together with at least 0. The semiconductor chip is formed by contacting a semiconductor wafer attached to a tape with an etchant while rotating the semiconductor wafer within an in-plane direction at a high speed or reciprocating the wafer laterally to uniformly etch the semiconductor wafer thereby reducing the thickness thereof, and dicing the thus reduced wafer. At least one unscheduled traffic queue holds plurality of unscheduled packets. A second substrate includes a second common electrode arranged facing the pixel electrode and set to the same potential as the first common electrode. The program file index stores the starting addresses and file size of all the program image files. A lubricant guiding mechanism is in the first shaft or in the drive housing.
