  • Patent number: 10456050
    Abstract: An artificial electronic skin according to the present disclosure comprises: a lower electrode; a first layer laminated on the lower electrode; a first micro dome formed on the first layer in a semispherical shape so as to stand upright upwards; a second layer laminated on the first layer; a second micro dome formed on the lower portion of the second layer, which lies opposite the first layer, in a semispherical shape to be able to engage with the first micro dome; an upper electrode laminated on the upper end surface of the second layer; and a pattern layer laminated on the upper end surface of the upper electrode so as to receive an external pressure applied thereto. The artificial electronic skin according to the present disclosure is advantageous in that a dynamic pressure, a static pressure, and a temperature can be sensed and distinguished by a single element, using different signals.

  • Patent number: 8402658
    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.

  • Patent number: 8236269
    Abstract: Disclosed are rigid random coils, having a contour length larger than a diameter thereof, an average bending ratio Db of 0.1˜0.8, and a weight average molecular weight of 1×108˜9×108 g/mole, and a resin composition or organic solvent composition including the same. The rigid random coils have the properties intermediate between those of polymers and rigid rod particles, and thus may be used as filler of various resins, aqueous solutions or organic solvents.

  • Publication number: 20050176869
    Abstract: The present invention relates to a heat absorb-release plastic composition and a molded product thereof, more specifically to a heat absorb-release plastic resin composition, which can sense a temperature at a specific temperature, has flexural strength, and can absorb or release heat as a latent heat, and a molded product thereof. The heat absorb-release plastic resin composition absorbs heat at a desired temperature as a latent heat and thus temperature increase is small, and therefore, it can be used for automobile interior decoration material, housing for an electric home appliances, etc. even if it has comparatively low Heat deflection temperature.
