An osmotic pump having a minimally compliant, volume-efficient piston positioned within a capsule is provided. The capsule has an interior surface, a beneficial agent, and an osmotic agent. The piston is movable with respect to an interior surface of the capsule, and defines a movable seal with the interior surface of the capsule. The movable seal separates the osmotic agent from the beneficial agent. The piston has a length-to-total-diameter ratio of about 1.1:1 and a core-diameter-to-total-diameter ratio of about 0.9:1. The piston enables greater beneficial agent and / or osmotic agent payload without increasing the size of the capsule. The osmotic agent imbibes liquid from a surrounding environment through a semipermeable body to cause the piston to move and, in turn, cause delivery of the beneficial agent from the capsule.

Traffic between logic LSIs and memory is increasing year by year and there is demand for increase of capacity of communication between them and reduction of power consumption in the communication. Communication distances between LSIs can be reduced by stacking the LSIs. However, in a simple stack of logic LSIs and memory LSIs, it is difficult to ensure heat dissipation to cope with increasing heat densities and ensure transmission characteristics for fast communication with the outside of the stacked package.

A piston connected with a piston rod is fitted in a cylinder having a hydraulic fluid sealed therein. A damping force is generated through extension and compression disk valves and an orifice. Vehicle height adjustment is performed with a self-leveling mechanism by transferring the hydraulic fluid between the cylinder and a hydraulic fluid tank.

Because the hydraulic fluid tank is formed without welding, it is possible to avoid contamination of the hydraulic fluid by welding sputter and thermal deformation. Provision of an O-ring on the outer flange portion can reduce the pressure acting from a reservoir on the clamped portion of the bladder and hence prevent dislodging of the bladder.
