Stoppers and solder tails are situated at the bottom of the housing of the card connector and extend in the perpendicular direction with respect to the housing. In one embodiment, the connector housing is inserted into a mount opening of a circuit board from a rear side of the circuit board. A portion of the housing may be positioned above the front surface of the circuit board while stoppers and solder tails are positioned on the rear surface of the circuit board. Since the solder tails are soldered to the circuit board, it is possible to reduce the height of the connector housing that extends over the front surface of the circuit board.

Abstract: A positive-displacement, steam-driven engine has a generally-elliptical rotor which is mounted within a cylindrical chamber. That rotor reciprocates as it rotates within that chamber; and interacting surfaces halt continued movement of that rotor whenever it reaches an end of its path of reciprocation, and then smoothly start that rotor moving back toward the opposite end of that path of reciprocation.
