Abstract: A method for quickly searching a cell at a mobile station by using a synchronization channel structure of a forward link in a code division multiple access system which operates by an asynchronous mode between base stations is provided. In the method, a predetermined starting point among a plurality of locations of sync channel codes in a frame with respect to a base station having a minimal channel loss is obtained. Long code group and frame sync information at the mobile station are obtained based on outputs of a matched filter every mini slot clock location for one frame time after a starting point of a current mini slot. A long code based on the obtained long code group and frame sync information obtained is detected wherein the long code is used for band-spreading of a forward link by a current base station.

First to third surface coolers for cooling surfaces of the rolled material are located on an entry side of each of first, second and third finishing mills of the finishing mill group, and the amount of cooling water jetted at the rolled material by each surface cooler under a command of a controller is set at 4,000 liters/min.multidot.m.sup.2, whereby the thickness of scale is restricted to 5 .mu.m or less.

Abstract: A battery monitoring device for a mobile communication terminal having a display. A current sink consumes a traffic mode current in response to a control signal output from a microprocessor. An analog-to-digital converter converts a voltage signal output from the current sink to a digital signal. The microprocessor compares the output signal of the analog-to-digital converter with threshold values stored in an internal memory to determine the remaining capacity of the battery. The remaining capacity of the battery is then displayed on the display.

Abstract: A switch apparatus of a portable cordless telephone for easily performing call incoming and originating functions by using an antenna. A push bar is formed at an edge of an antenna positioned inside a handset, and a push switch formed in the telephone receiver side of the handset has a contact part and a coupling part. The contact part has one protrusion end and another end coupled to the coupling part installed on a printed circuit board. Thus, when drawing the antenna to the exterior of the handset, the call incoming and the call originating functions are capable of being performed without an additional switch operation.
