Abstract: PURPOSE: A method of manufacturing a micro-lens of a charge coupled device(CCD) is to allow the micro-lens to be formed within unit pixel with a maximum size. CONSTITUTION: A planarizing layer is formed on a substrate for the formation of a CCD to protect a charge carrier electrode and a light blocking film. A color filter layer having a predetermined shape and an upper protective layer are formed on the planarizing layer. A photoresist film is coated on the protective layer and is patterned to form a photoresist pattern(40). The photoresist pattern is thermally flowed to form a micro-lens(42). The thermal flow controlled such that adjacent photoresist patterns are not in contact with each other. The photoresist pattern is rinsed using a PGMEA(PropyleneGlycol Monomethyl Ether Acetate)-based solvent to thereby expand the micro lens to have a maximum size within a unit pixel(P).

Abstract: PURPOSE: A connector is provided to improve the operational force of a pedal between an initial hinged point to jointed point of clevis by changed to long length, and to reduce the pedal treading force of a driver at a pull stroke position. CONSTITUTION: When the pedal(110) is on an initial position, the operational force of the pedal is small because the length of stroke is short for a leverage against an operating point of a push rod(140) is small. When the pedal(110) is moved to a full stroke position by the deep tread of the driver, a clevis pin(130) connecting the pedal(110) and the clevis(120) is guided by the guide portion of a bracket(100), the guide groove of the pedal(110) and the guide groove of the clevis(120). Thus, the guide pin approaches to the hinge point of the pedal(110). Therefore, the leverage of a push rod against the operational point of the push rod(140) is increased such that the pedal treading force of the driver is reduced.
