摘要:
An L-threonine-producing Escherichia coli strain and a method for producing the same are provided. The Escherchia coli strain contains chromosomal DNA with inactivated metJ gene. Therefore, expression repression of threonine biosynthesis genes by a metJ gene product is prevented, thereby producing a high concentration of threonine. Further, a high concentration of L-threonine can be produced in high yield using the method.

Disclosed is a method and system of forming an integrated circuit transistor having a reduced gate height that forms a laminated structure having a substrate, a gate conductor above the substrate, and at least one sacrificial layer above the gate conductor. The process patterns the laminated structure into at least one gate stack extending from the substrate, forms spacers adjacent to the gate stack, dopes regions of the substrate not protected by the spacers to form source and drain regions adjacent the gate stack, and removes the spacers and the sacrificial layer.

Provided are a magnetic sheet for use in a radio frequency identification (RFID) antenna, an RFID antenna including the magnetic sheet, and a method of manufacturing the magnetic sheet, in which the magnetic sheet includes an amorphous alloy selected from the group consisting of Fe—Si—B, Fe—Si—B—Cu—Nb, Fe—Zr—B and Co—Fe—Si—B. The magnetic sheet is made by laminating amorphous alloy ribbons made of an amorphous alloy between magnetic sheet layers formed of alloy powder including at least one amorphous alloy and then compression-molding the amorphous alloy ribbons, to thereby control microcrack of the amorphous alloy ribbons and enhance characteristic of an end-product. The magnetic sheet is also thin, and has an excellent magnetic permeability, and a simple manufacturing process.

A holder manufacturing method for loading a substrate of a semiconductor manufacturing device, a batch type boat having the holder, a loading/unloading method of a semiconductor substrate using the same, and a semiconductor manufacturing device having the same are disclosed. For example, the manufacturing method of the holder of the boat for loading a semiconductor substrate includes the steps of molding a holder substrate of a pipe shape having inner and outer circumference of a predetermined size in such a manner that a lower portion of the semiconductor substrate is seated thereon; and forming a plurality of holder rings by cutting the holder rings from the holder substrate in such a manner that each holder ring is matched to a disposal interval of the semiconductor substrates in the boat. The manufacture of the holder and the batch type boat are simple by means of the holder ring supported on the supporting rods and the end-effector escapes the supporting rods, so that the pitch interval can be minimized, whereby it can load the compact semiconductor substrate to the boat, the amount of the substrate treatment can be improved and thus the productivity thereof can be improved.

Disclosed is an electrochromic device comprising: (a) a first electrode; (b) a second electrode; (c) an electrochromic material; and (d) a gel polymer electrolyte containing an ionic liquid. A method for manufacturing the same is also disclosed. The electrochromic device uses a gel polymer electrolyte comprising an ionic liquid. Therefore, there is no problem related with electrolyte leakage. Additionally, it is possible to manufacture electrochromic devices by using plastic materials, because the ionic liquid gel polymer electrolyte permits structural deformation with ease. Further, because the electrochromic device uses an ionic liquid, it is possible to minimize side reactions between constitutional elements of an electrochromic device and electrolyte.

Disclosed is an electrolyte comprising a eutectic mixture formed of: (a) an amide group-containing compound; and (b) a lithum-free ionizable salt. An electrochemical device comprising the electrolyte is also disclosed. The electrolyte improves the quality of and electrochemical device due to the excellent conductivity of the metal cation contained in the eutectic mixture, a broad electrochemical window and low viscosity. Additionally, since the eutectic mixture has excellent thermal and chemical stability, it is possible to solve the problems of evaporation, exhaustion and ignition of electrolytes, to minimize side reactions between constitutional elements of the device and the electrolyte, and to improve the safety of the electrochemical device.
