Abstract: The present invention relates to a method and system for screening and separating biological specimens. The screening and separating method and system provide reliable results based on information related to the types, shapes, and positions of labeled products provided by an agent for accurate screening. In addition, the information related to the types, shapes, and positions can be combined to determine objective indices for the state of a target specimen, enabling rapid selection of the target specimen. The method and system for screening and separating biological specimens according to the present invention use an agent optimized to accurately and effectively create information on the selection of a target specimen and process images based on information on images stored in a server, enabling sensitive and highly reproducible screening evaluation.

Abstract: A nozzle system for an injector may include a casing that has an inlet through which liquid flows and an injector outlet through which liquid is outwardly injected, a swirler that is disposed inside the casing and includes at least one swirl groove formed in the exterior circumference thereof through which liquid passes and a swirl chamber formed between an end portion thereof and the injector outlet, and a needle for controlling liquid injection whereby swirl torque is generated when the liquid flows into the swirl chamber through the swirl groove and the liquid swirls in the swirl chamber.

Abstract: Disclosed is an apparatus for generating ICP, which has a heater having a hot wire as a heating source for heating elements in a chamber and inner wall of the chamber and also efficiently transfers heat of the heater through a heat transferring gas to the elements in the chamber and the inner wall of the chamber. According to the present invention, the elements in the chamber and the inner wall of the chamber can be heated up to a temperature of about 200° C., thereby reducing the adhesion of the by-product served as the source generating the undesirable particles. In addition, since the hot wire having a longer life span than the halogen lamp is used as heat radiating means, the life span of the apparatus is also increased.

Abstract: An apparatus and method for manufacturing solder balls used for an electrical and/or mechanical connection between a semiconductor chip and a substrate are provided. The apparatus includes a melting furnace having a nozzle through which a molten solder paste flows and drops, for producing solder balls; a vibrating mechanism attached to the nozzle of the melting furnace, for applying vibration to the nozzle; and a vibration controlling mechanism for controlling the vibration frequency of the vibrating mechanism to adjust the size of the solder balls dropped from the nozzle. The method includes the steps of setting a vibration frequency according to a desired solder ball size, applying vibration to a nozzle with the set vibration frequency, making the molten solder paste flow through the nozzle to manufacture solder balls of a predetermined size according to the vibration frequency, and measuring the size of the manufactured solder balls.
