  • Process for producing ferroelectric crystalline material
    Patent number: 4027074
    Abstract: Lead germanate, Pb.sub.5 Ge.sub.3 O.sub.11, or lead germanate/silicate in which up to 2/3 on a molar basis of the germanium has been substituted with silicon, can be formed from a glassy state to a ferroelectric state by a simple annealing process. The lead germanate or lead germanate/silicate is heated to a temperature sufficient to anneal it into a crystalline phase, then cooled below the ferroelectric transition temperature for the composition while an electric field is applied.

  • Multifaceted mirror structure for infrared radiation detector
    Patent number: 3972598
    Abstract: Infrared radiation can be gathered from a number of discrete, spaced apart fields of view and focused on a single sensing element with a multifaceted mirror. Each facet of the mirror is a concave surface, preferably spherical, which is oriented to gather infrared radiation from a predetermined field of view and reflect the infrared radiation to a radiation sensing element.
