20100096237 | Damper clutch of torque converter - A damper clutch of a torque converter of the present invention can reduce generation of abnormal vibration and a booming noise in low speed and also, can lower engaging torque and enhance fuel efficiency with multiple elastic damping force. A damper clutch of a torque converter includes a plurality of damper spring that are disposed along radial direction and a plurality of spring supporter that are disposed between the damper springs and pressurizes the damper springs along radial direction when power is delivered from a piston to a turbine, wherein each two spring supporters, putting opposite, form a group and each group has different length for supplying multiple elastic damping force. | 04-22-2010 |
20100204450 | Preparation Method for a Protein With New Function Through Simultaneous Incorporation of Functional Elements - Disclosed is a method for preparing a protein having a new function. The method comprises (A) a functional element-designing step of designing functional elements required for a new function desired to impart to an existing protein scaffold; (B) a functional element-inserting step of simultaneously inserting at least two gene fragments corresponding to the designed functional elements into a protein scaffold gene; and (C) a mutant screening and improving step of screening a mutant having a new function from a library of mutants inserted with the mutant genes, and improving and optimizing the function of the screened mutant using a directed evolution technique. The method for preparing can be widely used for the development of therapeutic proteins and the creation of industrial enzymes in the fields of bioengineering and biotechnology. | 08-12-2010 |
20120292154 | APPARATUS FOR REDUCING TRANSMISSION SHOCK IN AUTOMATIC TRANSMISSION - An apparatus for reducing transmission shock of an automatic transmission may include a piston operated by a control pressure, a clutch performing a clutching operation by an operation of the piston, and a cushion spring arranged between the piston and the clutch which varies by stages in stiffness of the spring with an operating position of the piston.
