Abstract: A seat moving device for a vehicle, includes: a lead screw having a male thread formed on the outer circumferential surface thereof, and arranged in the front-rear direction of the vehicle under the bottom surface of the interior space of the vehicle; a drive motor; a worm gear rotationally driven by the drive motor; a worm wheel rotating in engagement with the worm gear; a transmission gear rotating integrally with the worm wheel; a belt for power transmission engaged with a spur gear of the transmission gear, and formed in a closed curve shape; a moving wheel having a female thread engaged with the male screw formed on the inner circumferential surface thereof; and a gear box having an accommodation space formed therein for accommodating the worm gear, the worm wheel, the belt for power transmission, and the moving wheel.

Abstract: The present disclosure relates to a conductive aqueous ink composition for filling in an engraved micropattern, conductor-filled micropatterns fabricated using same, and a conductive device comprising same, wherein the conductive aqueous ink composition is conductive aqueous ink to be used for filling in an engraved micropattern formed on a substrate and can be applied to plastic bases, etc., and improve working environments due to low temperature sintering. The ink composition comprises: metal nanoparticles (A) protected by a dispersion stabilizer and ranging in particle size from 5 to 50 nm, metal particles (B) ranging in particle size from 100 to 900 nm; and a water-soluble solvent (C) having a boiling point of at least 150° C., the dispersion stabilizer containing a protective polymer composed of branched polyalkylene imine segments and polyoxyalkylene segments and an amine acid salt composed of an amine and an inorganic acid.

Abstract: A seat sliding apparatus for a vehicle is provided. The seat sliding apparatus may include a lead screw configured to define a first toothed part on an outer circumferential surface thereof, and disposed in forward and rearward directions of a vehicle, a worm gear rotated by a driving motor, a transmission gear assembly engaged with the worm gear to be rotated, a power transmission belt engaged with the transmission gear assembly, and a nut unit including a first nut configured such that a second toothed part engaged with the first toothed part is defined on an inner circumferential surface thereof, and a second nut configured to come into contact with the power transmission belt.

Abstract: A compressor pulley having a partially cold forged base of improved strength and a bridge of improved strength is easily manufactured. Metal is heated to a predetermined temp and then hot forged into a pulley shape. A piercing step then forms a through hold in a center portion of the pulley. The heated pulley is then cooled to room temperature. Then the pulley is rough guided. A partial cold-forging step forges the base at room temperature. A slot is then pierced in the base portion. During a finishing step, groove working and grinding are performed on a surface of the pulley.
