An apparatus for controlling fluid pressure recovery includes an elongated housing having an opening at a first end thereof, an opening at a second end thereof, an inner peripheral surface, and a fluid flow passageway therethrough. One exemplary system embodiment includes a bolster plate assembly for a semiconductor module assembly that includes a bolster plate and a leaf spring pre-loaded onto the bolster plate. The second end comprises a T-shaped connection, whereby a lateral attachment bar attaches to opposing sides of the game cart and the angled member connects at a third location. When the client is disconnected from the network, data required for constructing the virtual computer are saved in a file and that file is sent as it is to the client. The present invention conducts this test through a scan test, making it possible to automatically create test patterns with high circuit failure detection rate.
