摘要:
Disclosed is an exciter for generating physical vibration in response to the applied electric signal. In this device, a driving coil is attached to the periphery of an inner guide of a lower housing, and a rotor of permanent magnet is provided in the rotor-receiving space of the inner guide, both ends of the rotor being rotatably supported to the inner guide. An upper housing is engaged with the lower housing in such a manner that the upper housing surrounds the driving coil. In this device, the rotation shaft of the rotor is on a shifted state with respect to a center of a gravity of the rotor, by which means the exciter generates vibration through the upper and lower housings when the rotor rotates by the electromagnetic force of the driving coil.

Substituted sulfonamides are selective .beta..sub.3 adrenergic receptor agonists with very little .beta..sub.1 and .beta..sub.2 adrenergic receptor activity and as such the compounds are capable of increasing lipolysis and energy expenditure in cells. The compounds thus have potent activity in the treatment of Type II diabetes and obesity. The compounds can also be used to lower triglyceride levels and cholesterol levels or raise high density lipoprotein levels or to decrease gut motility. In addition, the compounds can be used to reduced neurogenic inflammation or as antidepressant agents. The compounds are prepared by coupling an aminoalkylphenyl-sulfonamide with an appropriately substituted epoxide. Compositions and methods for the use of the compounds in the treatment of diabetes and obesity and for lowering triglyceride levels and cholesterol levels or raising high density lipoprotein levels or for increasing gut motility are also disclosed.
