    摘要: A flexible transfer line for delivering coolant from a storage dewar to cool superconducting circuitry is provided with a delivery capillary coupled to the storage dewar, this capillary being thermally isolated from ambient temperatures. The transfer line has an outer flexible support coaxial with the delivery capillary, and an inner flexible shield between the delivery capillary and the outer flexible support. Heat in the shield is continuously removed to thereby provide the thermal isolation of the delivery capillary. The thermal isolation allows a low-flow rate of coolant through the delivery capillary since inefficiences due to thermal conduction and radiation are substantially eliminated.

    摘要: A system for delivering a cryogenic fluid to cool devices, such as electronic devices, in an open-cycle environment. The system comprises a dewar which stores a cold fluid, a cryogenic module for holding a device to be cooled and a cold fluid transfer line which delivers the cold fluid from the dewar to the device within the cryogenic module. The system further comprises an interlock mechanism to hold the transfer line and the dewar securely together and a coupling mechanism to allow the transfer line to securely engage the cryogenic module. The system also comprises a control subsystem which monitors and controls the flow of cold fluid from the dewar and through the transfer line.

    摘要: An improved open-cycle cooling apparatus in which a cooling chamber holding a device to be cooled is coupled with a cold fluid delivery system and, in which the cold fluid delivery system includes a delivery tube which directs a stream of cold fluid to strike the device and a return which vents the expended cold fluid from the cooling chamber. The improvement comprises a rigid enclosure formed within the chamber and configured to adaptively engage one end of the cold fluid delivery tube. The device to be cooled is disposed within the enclosure. The enclosure also includes a return to remove expended cold fluid from the cooling chamber to the return of the cold fluid delivery stystem. The improvement further comprises an alignment guide disposed within the enclosure between the device to be cooled and the one end of the cold fluid delivery tube engaged to the enclosure. The guide is configured to adaptively receive the one end of the cold fluid delivery tube and is disposed to accurately align the stream of cold fluid from the cold fluid delivery tube with the device to be cooled. The guide also permits the cooling chamber to rotate relative to the cold fluid delivery tube to compensate for any angular or twisting motion by the delivery tube.

    摘要: In a semiconductor inner lead bonding process, a connection component having leads is disposed on the chip surface so that the leads lie above the contacts. A bond region of each lead is forced downwardly by a tool into engagement with a contact on the chip while a first or proximal end of the lead remains attached to a dielectric support structure. The lead is deformed into an S-shaped configuration by moving the bonding tool horizontally towards the proximal or first end of the lead, thereby forcing the bonding region towards the first end and bending or buckling the lead. Alternatively, the lead is bent downwardly by a tool and the tool may then be disengaged from the lead, shifted away from the proximal end of the lead and again advanced downwardly to secure the lead to the chip contact.
