Title: Jet cutter
Inventor: JU NAM-SHIK
IPC: B24C3/00
Filed: 1992-10-21
Granted: 1995-02-02
Abstract: The jet cutter uses ice made from over cooled and highly pressured water to process the surface of a material. The water is changed to ice when injected in air through a nozzle in over cooled and highly pressured status. Solidified liquid processes the surface very well with its strong hardness; efficiency of a machining process depends on kinetic energy per unit area and difference of hardness when the liquid contacts with the surface. The jet cutter comprises a nozzle (2), a operating liquid container (3), a pump (4) compressing the operating liquid highly, a heat exchanger (5) making the liquid over cooled, a processing chamber (6) maintained under normal atmosphere, and a vacuum pump (7).

Abstract: Growth hormone releasing hormone (GHRH) receptor binding has been characterized using a unique binding assay utilizing iodinated GHRH probes. Photoaffinity GHRH probes have been constructed which allow for photolabeling and characterization of the receptor. In addition, high affinity biotinylated GHRH analogs have been constructed. Solubilization of GHRH-R/GHRH complexes and extraction of specifically bound GHRH using a mild detergent solution, followed by affinity chromotography, leads to a substantially purified GHRH-R isolate. Electrophoretic treatment of the GHRH-R isolate produces GHRH-R of sufficient purity to conduct sequencing of the receptor. Cloning of a gene encoding for polypeptides (protein or fragments thereof) having GHRH-R activity is accomplished using a bacterial host, and the cloned gene is expressed in a mammalian cell line.

Further, steering of the well is accomplished by dynamically ‎controlling the spatial phase and amplitude of the coherent symmetrical bidirectional ‎reciprocating deflections of the drill bit relative to a fixed terrestrial datum as the tool is ‎rotating, simultaneously pointing and pushing the bit. The amplitude and force of the ‎bit deflections can be variably controlled during steering operations to dynamically ‎adjust the instantaneous build rate as needed.
