Abstract: PURPOSE: A cooling air intake structure of an over-the-range is provided to improve the reliability of electrical equipment by sufficiently cooling the electrical equipment through the prevention of intake heat to a grille. CONSTITUTION: A cooling air intake structure of an over-the-range includes a grille(17) formed in the upper front face of a microwave oven for the intake air sucked into a microwave oven and a dividing guide(18) protruded onto the front lower end of the grille to divide hot air from a cavity from the external air. Upon starting cooking in the cavity, hot air in the cavity increases and the hot air leaks via a gap of a door(13) and a front plate(15). The leaked hot air forms airflows. Due to the dividing guide, the leaked hot air changes the direction downwardly from horizontal motion. Cold air is sucked into the grille while the leaked hot air is not sucked. Therefore, a heater in the upper portion of the microwave oven is cooled.

Abstract: A method and apparatus for performing inter-system hard handoff between communication systems or inter-frequency hard handoff within a CDMA communication system is disclosed. The purpose of this invention is to reduce the probability of dropped calls during inter-system hard handoff. In the event that a hard handoff attempt is unsuccessful, the mobile station will return to the original system with information which the communication system of the present invention uses to assist in the performance of future handoff attempts. Alternatively, with no handoff attempt made, the mobile station monitors the destination system then returns to the original system with information used to assist in subsequent handoff attempts. The information returned from monitoring a CDMA system consists of results of a search for one or more pilots given at offsets in a specific list provided to the mobile station by the base station or a set of offsets based upon a predetermined search algorithm.

Abstract: PURPOSE: An apparatus for reducing pressure loss of a cyclone dust collector is provided to make an eddy current movement laminar when the air sucked into a cyclone body is discharged via an air discharge path. CONSTITUTION: A pressure reduction apparatus comprises: a cyclone body(100); an air suction path(110) connected to the cyclone body and for sucking air or foreign materials; an air discharge path(120) for discharging the sucked air; a foreign material discharge hole(100a) for discharging the foreign materials separated from air in the cyclone body; and a laminar-flow unit(140) placed on an axial line formed by the air discharge path and for laminar-flow an eddy current by removing a whirling force of the air discharged via the air discharge path. Air and foreign materials are sucked into the cyclone body and centrifugally rotated along the inner wall of the cyclone body. The air collecting to the lower center portion of the cyclone body forms a discharge stream and then flows out via the discharge path. The foreign materials heavier than air is rotated centrifugally and collected in a dust collection box(130). Fine dust contained in the discharged air collides against a cross blade(140) and springs out toward the inner wall of the cyclone body. The fine dust is discharged into the dust collection box while jumping on the foreign materials. Accordingly, the flow of the discharged air stream becomes smooth while preponderance of the fine dust into the discharged air stream is avoided. Therefore, pure air is discharged out of the cyclone body.
