Abstract: The present invention relates to donepezil ether palmitate hydrochloride (DEP HCl) and a method for preparing same. Donepezil ether palmitate hydrochloride (DEP HCl) has been developed to have increased stability by suppressing generation of unknown related substances generated during a preparation process of a raw material and formulation of donepezil ether palmitate (DEP). In addition, the present invention relates to a sustained-release pharmaceutical composition comprising donepezil ether palmitate hydrochloride (DEP HCl) as a main ingredient. When administered in the body, the initial release of donepezil, which is an active ingredient, is reduced, thereby reducing the risk of side effects such as drug toxicity, and the constant release of donepezil in the body for a long period of time can improve the drug treatment effect on dementia patients.

Abstract: The present invention relates to novel donepezil ether palmitate or a pharmaceutically acceptable salt thereof; and a sustained-release pharmaceutical composition containing same as a main ingredient. Since an ether palmitate group is introduced to donepezil, the donepezil ether palmitate of the present invention reduces the initial release of donepezil, which is the active ingredient, when administered into the body, so as to reduce the risk of side effects such as drug toxicity, and allows donepezil to be uniformly released in the body over a long time to increase drug treatment effects for dementia patients.

Abstract: An electric motor includes a stator, a rotor having a rotating shaft, first and second bearings each having an outer ring, balls, and an inner ring, and spaced apart axially from each other, a preload washer including a shaft section having a preset fixed length in the axial direction, and an elastically-deformable portion extending from one end portion of the shaft section to be elastically deformable, the preload washer applying a preset intensity of preload to the inner ring of the first or second bearing, and a coupling member screwed into an end portion of the rotating shaft and elastically deforming the preload washer in the axial direction. This structure may result in preventing an excessive preload from being applied to the bearing and allowing a preset preload to be stably maintained when thrust is applied.
