This invention relates to an integrally formed micro extending type elastic probe, comprising a main body and a probe needle capable of relatively moving to the main body axially, wherein the probe needle is electrically connected to one end of the main body with a spring structure. When the probe needle gradually closes to the free end of the main body, the spring structure appears to be in an ex...

A wastewater treating system includes: a vessel defining a vessel space therein, the vessel space being partitioned into an activated sludge zone that is adapted to receive waste water and a body of an activated sludge therein, and a coarse filtering zone that is disposed downstream of and that is in fluid communication with the activated sludge zone for receiving bio-treated wastewater from the a...

PURPOSE: Provided are an apparatus and a method for molding quartz glass, which permits a surface having a relatively large area to be formed homogeneously by hot press molding. CONSTITUTION: The apparatus(10) for molding quartz glass comprises: a mold(15) having a hollow portion(21) for housing quartz glass and an expansion coefficient greater than that of quartz glass; a pressurizing portion dis...

A method for manufacturing high quality glass panel includes producing a substantially planar glass sheet (32) having a first portion (34) and an end portion (36), wherein the first portion (34) and the end portion (36) are both in a substantially vertical first orientation, and twisting the end portion (36) of the glass sheet (32) to a second orientation (B) that is different from the first orien...

The present invention is directed toward a method of reducing contamination of a glass melt by oxide particulates, such as particulates of platinum oxide, which may condense on the inside surfaces of a stir chamber, particularly the stir shaft, and fall back into the glass melt. The method includes causing a flow of gas through an annular space between the shaft and the chamber cover. In one embod...

A method of forming an oxide glass including heating a glass melt having a beta-OH concentration of at least about 0.35 in a vessel comprising a metal selected from the group consisting of platinum, molybdenum, palladium, rhodium, and alloys thereof, there being an interface present between the vessel and the glass, and controlling a partial pressure of hydrogen in an atmosphere in contact with an...

Feed materials are melted in a furnace to form a glass melt at a first temperature T1, the glass melt containing at least one fining agent. The glass melt is cooled to a second temperature T2 less than T1, and an oxygen-containing gas is bubbled through the cooled melt. The glass melt is then re-heated to a third temperature T3 equal to or greater than the first temperature T1.
