ABSTRACT:
A powder supplying apparatus supplies, for example, a powder spraying apparatus with fine powder particles such as of ceramics having particle sizes of several .mu.m to 10 .mu.m at an extremely small rate of several grams to several tens of grams per hour, in the form of micronized discrete particles dispersed at a high degree of uniformity. The powder spraying apparatus is capable of spraying the fine powder particles on an object surface with a high degree of uniformity of distribution. The disclosed apparatus is used typically in uniformly spraying the above-mentioned fine powder particles which serve as spacers between a pair of transparent substrates of a liquid crystal display panel, for the purpose of maintaining a uniform and constant gap to be filled with a liquid crystal between these transparent substrates.
