The present application describes deuterium-enriched risperidone, pharmaceutically acceptable salt forms thereof, and methods of treating using the same. Along with a display of a list of search results, new query candidates as well as the hit counts returned with those queries are presented. The third lower electrode 106 and the second upper electrode 105 are located to face each other, and the third upper electrode 107 and the second lower electrode 104 are located to face each other. The combs change the flow pattern of the fluid and act as a momentum channeling mechanism relative to the actuator assembly and suspension assemblies resulting in a considerable reduction in track misregistration error. In response to the determination of whether the external information and the internal information agree with each other, it is determined whether the handle is properly grasped based on a force detected by a six-axis force sensor provided on each hand.
