Abstract: Contact pin temperature of a semiconductor package is reduced by forcing air into a region between a circuit board and a socket body. A sealant around the perimeter of the socket body at least in part seals the socket body with the circuit board, allowing the forced gas to flow through cavities containing the contacts, thereby cooling the contacts and the package pins. The contact-pin temperature may be reduced, allowing power pins to carry more current. Accordingly, microprocessors and processing systems may be operated at higher data rates without reducing reliability or increasing contact-pin oxidation.

Abstract: With an accelerator for accelerating an electron beam by a voltage of about 400 KV having a stability of 10.sup.-6, it is difficult to use a flexible, insulated cable to feed the output from a power supply to an electron beam and an accelerating tube. Accordingly, the present invention employs a rodlike connector instead of such an insulated cable. A guide means is provided to permit the movement of a power supply column in the direction of the axis of the connector. This facilitates cleaning or otherwise maintaining the power supply column, the electron gun, and the accelerating tube.

Abstract: A pressure regulating device for fluidtight, fluid-filled apparatus comprises a solid body with a shallow recess in a surface enclosed by a flexible diaphragm. A narrow passage, preferably of capillary dimensions, connects the recess to the interior of the apparatus and the diaphragm is flexible enough to be deformed without injury so as to enter the recess and reduce its volume substantially and preferably practically to zero. The recess contains a volume of air which for optimum performance should be equal to the amount by which the volume can be reduced by movement of the diaphragm and also equal to the volume expansion of the fluid (or if more than one device is fitted its share of the fluid) from atmospheric conditions to mean working temperature (less the volume of any air occluded elsewhere in the apparatus). By this means, the diaphragm is substantially unstressed both under atmospheric conditions and under mean working conditions, since the gas will be compressed to a negligible volume.
