The wet treatment liquid feed nozzle of the invention comprises an introducing pathhaving an introducing porta discharging pathhaving a discharging porta crossing sectionformed by causing the introducing pathand the discharging pathto cross at the other ends thereof, a nozzle assemblyhaving an opening sectionopening to an object to be treatedprovided at the crossing sectionand pressure control meansfor controlling the difference between the pressure of the wet treatment liquid in contact with the object to be treatedand the atmospheric pressure provided at least on the discharging pathside so that the wet treatment liquid having been in contact with the object to be treatedvia the opening sectiondoes not flow to outside the discharging path

Liquid feed nozzle, wet treatment, apparatus and wet treatment method

The wet treatment liquid feed nozzle of the invention comprises an introducing path having an introducing port, a discharging path having a discharging port, a crossing section formed by causing the introducing path and the discharging path to cross at the other ends thereof, a nozzle assembly having an opening section opening to an object to be treated, provided at the crossing section, and pressure control means, for controlling the difference between the pressure of the wet treatment liquid in contact with the object to be treated and the atmospheric pressure provided at least on the discharging path side so that the wet treatment liquid having been in contact with the object to be treated via the opening section does not flow to outside the discharging path.

Liquid feed nozzle, wet treatment apparatus and wet treatment method

There are provided a method and an apparatus for removing electrostatic charges from high resistivity liquid. An insulating film is formed on the surface of a conductive element which is in contact with the high resistivity liquid wherein the insulating film has such a thickness that a tunneling current may flow through the insulating film, thereby preventing the highly purified high resistivity liquid from being contaminated, as well as from becoming acid. Thus, objects to be treated with the high resistivity liquid become free of electrostatic charges without any contamination.

A liquid crystal display capable of freely changing between the state of having a large viewing angle and the state of having a small viewing angle according to one's need, and an electronic apparatus using the liquid crystal display. A pair of substrates having respective surfaces opposed to each other are provided and a liquid crystal is provided between the substrates. A common electrode and an alignment film are successively formed on the opposed surface of one of the pair of substrates. A multiplicity of pixel electrodes are provided on the opposed surface of the other substrate so as to cover display regions of the liquid crystal. An electroconductive black matrix is provided on the other substrate while being electrically insulated from the pixel electrodes, the black matrix being formed at peripheral portions of the pixel electrodes and over non-display regions of the liquid crystal. Another alignment film is provided over the pixel electrodes and the black matrix. A switch is provided to divide a pixel region formed corresponding to each pixel electrode into two by applying a potential to the black matrix. The switch changes the two pixel regions formed corresponding to each pixel electrode into one when no potential is applied to the black matrix.

Method for removing electrostatic charge from high resistivity liquid

An etchant which generates neither heat nor gas during the process, does not sublimate, is stable for a long period of time, requires no special pipings, and further requires no special treatment of waste water because of containing no organic solvents. The etchant is a solution containing hydrofluoric acid and an-oxoacid or oxoacid salt compound expressed by Mm(XOn)p (where M is hydrogen, one-to three-valence metal or NH.sub.4, m is 1 or 5, X is a halogen element, n is 3, 4 or 6, and p is 1, 2 or 3).
