A miniature 1/4-inch diameter 24-pin plug and receptacle

Miniature plug and receptacle, which eliminates the need for permanent fixed leads, is used on wind-tunnel force balances, in the interface connections of microelectronic modular assemblies, and in electric and electronic systems where subsystems must be removed or interchanged.

Increasing the response of PIN photodiodes to the ultraviolet

Solid state device uses sapphire windows and avoids coatings which absorb ultraviolet radiation and ultimately alter detector geometry. Ultimate solution for ultraviolet response is geometry with maximum peripheral area and horizontal field structure to draw out photon induced current carriers.

Adding through-bolt holes to pin-fin cold plates

Spot-welding technique is less expensive than secondary-brazing and electron-beam methods. With procedure, standard plates can be modified in quantity for various mounting configurations without need for special tooling.

Development of far infrared attenuation to measure electron densities in cw pin discharge lasers

A two beam attenuation technique was devised to measure electron densities 10 to the 9th power to 10 to the 11th power cm/3 resolved to 1 cm, in a near atmospheric COFFEE laser discharge, using 496 micrometer and 1,220 micrometer radiations from CH3F, optically pumped by a CO2 laser. A far infrared generator was developed which was suitable except for a periodic intensity variation in FIR output deriving from frequency variation of the pump radiation.
