A nonionic hydrophilic macromolecule without added lubricating oil provides lubrication to textured at least partially oriented yarns to protect the yarns during subsequent processing, such as weaving to improve weaving efficiency. A touch-panel flexible wiring substrate is mounted to the touch panel. In the structure, superior insulation properties may be obtained even if the compressor size is reduced, and the productivity and assembling performance of the compressor may be improved. Also presented are various methods of operating an ion mobility spectrometer including, but not limited to, a continuous first dimension ionization methods that can enable ionization of all chemical components in the sample regardless their charge affinity.
