Abstract: The present invention relates to electrode slurry coating apparatus and method, the present invention ultimately allowing the process efficiency to be increased and rate of errors to be reduced when double-layer structured active material layers are formed by temporally adjusting the height of first and second discharge outlets through which active material is discharged.

Abstract: A porous paper sheet includes a first base material; and paper pieces laminated on the first base material, and adhered to each other or adhered to the first base material using an adhesive such that the paper pieces have predetermined pores therebetween. The paper pieces are shredded in a predetermined size. A device for manufacturing the porous paper sheet, includes: a first base material feeder feeding a first base material; a conveyor unit including a conveyor belt on which the first base material is placed and rollers driving the conveyor belt; an adhesive nozzle positioned above the conveyor belt and applying an adhesive to the first base material; and a paper piece feeder positioned above the conveyor belt and feeding paper pieces to the first base material.

Abstract: Disclosed is a hydraulic brake booster. A relative movement structure of a control plunger and an output shaft is modified in such a manner that the output shaft operates in the control plunger, thereby reducing the overall length of the booster and the manufacturing cost. An inner circumferential surface of a guide of the control plunger does not make contact with an outer circumferential surface of the output shaft, so that the vibration and the impact caused by the contact between the control plunger and the output shaft are not delivered, thereby improving brake pedal feeling. The control plunger includes a guide having a groove, and an inner diameter of the guide is greater than an outer diameter of the output shaft. The control plunger and the output shaft perform relative movement in the overlap state therebetween, thereby reducing the overall length of the booster and the manufacturing cost.

Abstract: The present invention relates to a composition for improving drought stress tolerance in a plant, a transgenic plant with enhanced drought stress tolerance, and a method for preparing a transgenic plant. The novel functional plant having excellent drought stress-tolerance may be prepared using the composition for improving drought stress tolerance and a method for preparing a transgenic plant.

Abstract: The present invention relates to proteins and nucleic acids related to salt tolerance in plants.

Abstract: A transmission using a flat gear and a grooved flat gear is provided. The transmission includes a flat gear having a speed stage constituted by a predetermined number of grooves formed in a circle on a circular plate or a grooved flat gear having a plurality of speed stages constituted by a predetermined number of grooves formed in concentric circles on a circular plate in a rotary direction and an open groove which is common to the plurality of speed stages. Accordingly, a single flat gear or grooved flat gear is perpendicularly coupled to at least one bevel gear disposed at a power shaft for power transmission and speed change, thereby solving the problems of contamination of a coating due to lubricant, derailment of a chain, or irregular transmission time occurring in a chain type transmission.

Abstract: The present invention provides plant amino acid:glyoxylate aminotransferase genes. Also disclosed are the recombinant production of these plant amino acid:glyoxylate aminotransferase enzymes in heterologous hosts, screening chemicals for herbicidal activity using these recombinantly produced enzymes, and the use of thereby identified herbicidal chemicals to suppress the growth of undesired vegetation. Furthermore, the present invention provides methods for the development of herbicide tolerance in plants, plant tissues, plant seeds, and plant cells using the amino acid:glyoxylate aminotransferase genes of the invention.

Abstract: A method of producing alumina-silica ceramic with mullite whisker structure has been produced as armor materials for protecting high velocity projectile. The mixing composition of starting powders consists of alumina, quartz, kaoline, feldspar and talc, and the green compacts were sintered at the temperature range from 1200 to 1450° C. for 0.5 to 3 hours. Mullite whisker structure in the ceramic was fabricated and grown in the period of liquid phase sintering. The whisker phase of mullite is homogeneously distributed in the ceramic.
