The material, and in most general applications the contact made from the material, essentially consists of silver, approximately 15% cadmium oxide by weight, and lithium carbonate at a proportion of about 0.005 weight percent of lithium, which is approximately equal to 0.04 molecular percent of lithium carbonate.

Abstract: The disclosure relates to an apparatus and method for recording images on recording mediums which images correspond to high energy radiation patterns. A temporary storage medium, such as an infrared-stimulable phosphor or thermoluminescent material, is exposed to an incident pattern of high energy radiation. A time interval after exposure, a small area beam of long wave length radiation or heat scans the screen to release the stored energy as light. An appropriate sensor receives the light emitted by the screen and produces electrical energy in accordance with the light received. The information carried by the electrical energy is transformed into a recorded image by scanning an information storage medium with a light beam which is intensity modulated in accordance with the electrical energy. Although the invention can be used at any reproduction ratio, it is particularly usable in recording images representative of large format high energy patterns onto microfilm.

Abstract: A garment waistband that employs a longitudinally extensible elastic band which is laterally partially stiffened. A plurality of elastic threads extending in the longitudinal direction through the band are bound to stiffened lateral fibers, and the stiffened lateral fibers are loosely interconnected by supporting fibers. The extension of the elasic band is partially restrained by a fabric web attached to parts of the inner and outer surfaces of the elastic band. The looseness with which the supporting fibers connect the stiffened fibers allows one longitudinal portion of the waistband to be stretched without significantly affecting nearby parallel longitudinal portions. The fabric web partially restrains extension of the elastic band so that the garment to which it is attached does not pucker or significantly deform. The result is a waistband that conforms in a comfortable manner to body contours while providing stability and a neat, finished appearance to the garment in which it is employed.

Abstract: Disclosed is a manufacturing method of forming silicon gate, self-aligned MOS-type devices having submicron dimensions. After forming the gate from a highly doped polysilicon layer using a mask, the structure is subjected to a low temperature (700-750 degrees C.) thermal oxidation.
