Abstract: A multi-purpose digital damping device and application thereof is disclosed. The device comprises a mandrel, a movement disc disposed in a middle section of the mandrel, a first body and a second body rotationally connected to the mandrel, an inertia wheel rotationally connected coaxially to the mandrel, a pulse-width modulation circuit electrically connected to a coil. The first body and the second body are disposed respectively on each side of the movement disc and are merged by a seal ring to form a sealing cavity. A magnetic powder and the movement disc are both disposed in the sealing cavity. A coil frame for coil mounting is provided outside of the sealing cavity. The coil is mounted on the coil frame. A third body is provided for enclosing the coil on the coil frame. The third body is detachably connected respectively to the first body and the second body.

Abstract: The present invention relates to tetrahydroprotoberberines of the formula (I) and the physiologically acceptable salts thereof. The invention also relates to the use of the compounds of the formula (I) or pharmaceutically acceptable salts thereof for preparing a pharmaceutical composition for the treatment of a medical disorder susceptible to treatment with dopamine receptor ligand, such as schizophrenia.
