The present invention provides a process for preparing olmesartan medoxomil. Moreover, the production and assembly of the high-pressure fuel pump of the invention are simplified by the use of ball valves. The dynamic stabilization device is also configured so that the dual spring member does not undergo stresses greater than an effective fatigue limit that is related to a fatigue limit of the spring. First ends of the rear arm and the front arm opposite to the connecting member are correspondingly pivotably connected to a stationary rail and a movable rail of one of the slide rail apparatuses. The cover is alternatively releasably removable to expose the ultraviolet lamp and enable it to be immersed in a liquid to disinfect the liquid. Other embodiments may be described andor claimed.
