Abstract: A mobile communication device is provided that includes a first body, a second body hingedly-coupled to the first body and speaker unit installed in the second body such that sound generated when the first body is folded closed with respect to the second body can be directly transferred outside the mobile communication device. Using the present invention, a user can listen to high-quality reproduced sound without distortion even when the first body is folded closed with respect to the second body and reliability and competitiveness of a product can be improved.

Abstract: A monitor apparatus including a monitor main body to display a picture, and a base supporting the monitor main body, the monitor apparatus including: a link provided between the monitor main body and the base; a monitor hinge interposed between the monitor main body and the link and rotatably supporting the monitor main body to the base; a base hinge having a base bracket interposed between the base and the link and rotatably supporting the link to the base; a protruding portion formed in one of the base bracket and the link; and a rotation restricting portion provided in the other one of the base bracket and the link, elastically contacting the protruding portion, and preventing the link from rotation so as to keep the monitor main body rotated in a position parallel with the base. With this configuration, a link of a monitor is prevented from being rotated due to the weight thereof and the link when the monitor is in parallel with a base.

Abstract: A key top comprising a key stem provided at a lower portion of the key top to be inserted into a rubber cup unit; and a first spring provided at a lower end of the key stem, and comprising a plate spring, wherein the key top is pushed down by finger pressure to turn on a contact point, thus executing key-in operation.

Abstract: Disclosed is a method for performing authorization of an ignition key by using an engine control unit (ECU) and an ignition key that stores a key ID, a lock password and a key password.

Abstract: The present invention relates to a microgranule prepared by using an alkali compound as a stabilizer for a 5-pyrrolyl-2-pyridylmethylsulfinylbenzimidazole derivative having the following formula (1), which is a very effective antiulcerative but highly unstable under acidic conditions, and by using a water-soluble polymer as a binding agent. in which X, R1, R2, R3, R4 and R5 are defined as described in the specification.

Abstract: A charger assembly for a wafer carrying apparatus, includes a charger for conveying wafers loaded in a plurality of grooves of a boat to a subsequent manufacturing process. The charger has a plurality of wafer guiders disposed side by side and has a first gap therebetween. The charger further includes an adjusting structure by which the first gap between the plurality of guiders is aligned with a second gap formed between groove groups of the boat. A pair of supporting members are detachably attached to the wafer guiders by fasteners to allow lateral movement of the wafers guiders to ensure correct alignment of the grooves of the boat and charger.

Abstract: A dust cleaning nozzle for cleaning a cathode ray tube comprises a pipe with an axially extending hollow part, and an ejecting angle changing mechanism attached to one end of the pipe. The nozzle, after insertion through the neck of the cathode ray tube, changes the ejecting angle of air ejected from the ejecting angle chainging mechanism with respect to the axis of the pipe so as to be efficient in removing dust from the tube.
