This specification covers the requirements and test methods for direct-reading liquid crystal forehead thermometers, in either the continuous or intermittent reading modes, designed to monitor trends or measure human forehead surface temperatures, or both. When examined by test methods...
Material Description. This specification covers the requirements for crystal refiner materials for zinc phosphate coatings applied to bare metal substrates. These conditioners are only intended to be used in conjunction with a specifically approved zinc phosphate system (9984090 and 9984123)...
Sunlight readable transflective liquid crystal displays, used on devices from cell phones and portable media players, to GPS and even some desktop monitors, have become indispensable in our day-to-day lives. Transflective Liquid Crystal Displays is a methodical examination of this...
Crystal growth is the art and science of growing crystals to facilitate high-technology applications in lasers, semiconducting devices, computers, magnetic and optical devices, optical processors, and pharmaceuticals, among others. This Field Guide examines the basic phenomena and...
Section 1 covers 4 categories of glass, is technically identical with the EEC Directive on crystal glass and is intended for reference in the statutory instrument which will implement this Directive in the UK. Section 2 incorporates certain requirements additional to those in the EEC...
INTRODUCTION This standard, which shows quartz crystal unit holder outlines and pin connections, includes the outlines previously shown in RETMA Standard RS-192, July 1957; those of interest to the U. S. published in International Electrotechnical Commission (I.E.C.) publication...
This standard establishes the external dimensions of envelopes for the encapsulation of quam resonators in their sealed or closed configuration. To the extent found feasible the outlines are arranged in "families", with all outlines within a family sharing a single major defining character. A...
