"1. A piston and cylinder assembly of a positive displacement machine, the assembly comprising a piston reciprocably（＊摺動可能に）disposed within a cylinder having an axis, a cylindrical bearing surface and a uniform diameter, the piston comprising: 
a bearing surface having an axial length and defining a diametrical clearance with the cylindrical bearing surface of the cylinder of up to about two percent of the diameter of the cylinder, the diametrical clearance defining a lubrication gap and a hydrodynamic seal between the piston and the cylinder; and

"Systems and methods are shown for electrically controllably transmitting power（動力）from a motor involving electrically controllably coupling the first input hub to a shuttle so that power is transmitted from the first input hub to the shuttle, providing for one-way rotation between the shuttle and a stationary chassis, and coupling the shuttle to an output hub with a spring such that energy is stored and released from the spring as the output hub rotates. Examples are shown that include controlling engaged and disengaged time intervals of the first input hub and shuttle to maintain a torque level at the output hub, such as by utilizing（用いる）pulse width modulation or pulse frequency modulation. Examples are also shown involving electroadhesively（電気吸着で）coupling the first input hub to the shuttle."
