摘要： To provide an ultrasonic cleaning device (1) that ensures stable operation of a vibrating element for generating ultrasonic without a complex structure and distribution of a great quantity of a cleaning liquid and (2) that is capable of cleaning upper and lower surfaces of a cleaning target easily, an ultrasonic cleaning section of the device is provided with an upper cleaning-liquid-supply nozzle and a lower cleaning-liquid-supply nozzle for projection of ultrasonic. The upper cleaning-liquid-supply nozzle supplies an upper surface cleaning liquid to an upper surface of a glass substrate. The lower cleaning-liquid-supply nozzle supplies the lower surface cleaning liquid to a lower surface of the substrate in a form of shower to which ultrasonic has been projected. A vibrating element for generating ultrasonic to be projected to the lower surface cleaning liquid is provided in a cleaning liquid distribution path that extends from an upstream side to a downstream side in a direction in a range of a horizontal direction to an upward direction.

摘要： This invention provides a method and apparatus for recovering In in the form of an alloy or a metal simple substance as a valuable material from waste LCD. In the In recovery method and apparatus, there is no need to recover In as indium hydroxide, and In can be recovered as a valuable metal. Accordingly, unlike the case of indium hydroxide, the recovery does not suffer from poor handling, and In can easily be recovered through a filter or the like with significantly improved In recovery. The In recovery method is characterized by comprising crushing waste LCD containing indium tin oxide, dissolving indium tin oxide from the crushed waste LCD with an acid to give an indium compound-containing solution, allowing the solution to flow into a reactor for recovery and, further, adding particles of a metal having a larger ionization tendency than In into the reactor for recovery, fluidizing the metal particles, precipitating In or an In alloy contained in the indium compound-containing solution onto the surface of the metal particles, then separating the precipitated In or In alloy from the metal particles by separation means, and separating and recovering the separated solid In or In alloy from the liquid component.

摘要： The invention provides an indium adsorbent that can cause indium to be adsorbed, and a simple and inexpensive indium fractioning method for isolating and recovering high-purity indium from an acid solution whose primary component is hydrochloric acid and that contains indium. A primary component of the indium adsorbent is an anion-exchange resin that has a crosslinked structure produced by the copolymerization of styrene or acrylamide and divinylbenzene, and at least one of a quaternary ammonium group and a tertiary ammonium group, and that is provided with an acid-adsorbing ability. An acid solution whose primary component is hydrochloric acid and that includes indium is brought into contact with the anion-exchange resin to cause indium to be adsorbed to the anion-exchange resin.
