Abstract:
PURPOSE: A rotary compliant joint using a spring and a damper adopting magneto rheological fluid is provided to have a manual compliant function against external force by using the spring, to reduce shock applied in colliding peripheral objects or persons with machines having joints or robots, and to prevent accidents and breakages of the joint by minimizing impulse applied to the objects and the joint to the reduction of shock. CONSTITUTION: A rotary compliant joint(100) for mutually connecting first and second links to relatively rotate is composed of a housing(111) connected with a driving unit to rotate and rotatively fixed for the first link; a rotor(161) of which one end is rotatively inserted into the housing and the other end is connected to the second link; magneto rheological fluid(115) filled between the inside of the housing and the rotor to change yield stress to magnetic flux density; a plurality of springs(169) inserted into a circular groove(112) formed at the side of the housing facing the second link; and a cover(163) fixed to the other end of the rotor to close the groove and to expand and contract the springs with interlocking to the second link.

Abstract:
PURPOSE: Human serum albumin is over expressed in Hansenula polymorpha DL-1 transformed with HSA gene under the control of methanol oxidase gene promoter. CONSTITUTION: The invention is disclosed transformed yeasts Hansenula polymorpha DL-1 which has integrated HSA gene, isolated from human fetal liver cDNA library and removed 5'UTR without signal sequence, controlled by methanol oxidase gene promoter. Transformed yeast is cultured in YPM medium( 1 % of yeast extract, 2 % of Bacto peptone, and 2 % of methanol) at 37°C for 72 hrs. Methanol is supplied at every 12 hrs to keep the concentration 2 % of methanol in the medium constant after 24 hrs. The concentration of expressed HSA is 40-50 mg/l by western blotting compared with authentic standard HSA. This method also detects smaller degraded HSA proteins in the medium.
Abstract:
A method for manufacturing a graphene electronic element includes: a step of forming a graphene layer on a metal substrate; a step of forming a metal protection layer by depositing a first metal onto the graphene layer; a step of forming an imaging support layer on the metal protection layer; a step of removing the metal substrate from the graphene layer; a step of imaging a graphene imaging layer made up of the graphene layer, the metal protection layer, and the imaging support layer onto a target substrate; a step of exposing the metal protection layer by removing the imaging support layer; a step of forming an electrode by depositing a second metal onto the metal protection layer; and a step of forming a metal protection pattern only on the bottom of the electrode by removing only the exposed part of the metal protection layer. Therefore, the features of a graphene electronic element are enhanced as the surface of the graphene layer is protected.
