A method is disclosed for calculating the optimal number of base transceiver stations (BTSs) in a wireless network and for determining a loading factor value therefor. The wireless network has a plurality of BTSs, each station providing communication service to mobile stations. As a loading factor value increases, the traffic decreases and the coverage area increases. The method calculates the number of BTSs in accordance with a decrease in traffic and the number of BTSs in accordance with an increase in the coverage area; determines a loading factor value which minimizes a difference between the two number of BTSs; and determines the optimal number of BTSs according to the determined loading factor value.

A disk player which reproduces information recorded on a disk, includes a housing in the front of which an aperture is formed. A disk tray is installed to move into and out of the housing through the aperture and has an upper surface on which a disk is placed. A deck is installed under the disk tray in the housing. A turntable for rotating the disk and an optical pickup for reading information of the disk are installed on the deck. A mechanism is provided for lifting the deck while keeping the deck level. Thus, the disk can be positively clamped since a deck on which a turntable is installed ascends while keeping level.

A ginseng processing method and a processed ginseng prepared by the processing method are provided. The ginseng processing method includes the steps of: mixing 10.about.99.5 wt % of grapes and/or wild grapes with 0.5.about.90 wt % of ginseng; adding water to the mixture of grapes and/or wild grapes with ginseng with a weight ratio of 1.about.10:1; heating the mixture at 45.about.130.degree. C. for 1.about.70 hours; and cooling the heated mixture to room temperature. According to the ginseng processing method using grapes and/or wild grapes, the side effects caused by taking only ginseng are decreased or eliminated. Also, the browning of the ginseng is facilitated, reducing the amount of effort and time required for processing the ginseng. Also, the processed ginseng is acceptable to many persons in taste, aroma and color, and can be used in various forms for various purposes.

A heating pot for decocting Chinese herbs, including a container on which Chinese herbs are to be contained, a heater received in the container so as not to contact the container, and a condenser installed on the opening of the container, for condensing important medicinal elements contained in vapor. The heater has a ray generation means for generating high temperature infrared rays toward the container, a main reflection means for reflecting the infrared rays to the container, and a follower member which has a lateral follower extending from the side of the heater for shielding the side of the condenser installed in the container, and an upper follower coupled to the top of the lateral follower for shielding the upper portion of the condenser.

An open cable applying apparatus capable of providing an internet search and an internet providing method using the applying apparatus. The open cable applying apparatus includes a PCMCIA interface unit to mount any one of a POD module and a LAN card having PCMCIA (Personal Computer Card International Association) standards, a web browser driving unit to drive a web browser to generate a certain web page, and a control unit to switch the mode in the apparatus to an internet mode if it is determined that the LAN card having PCMCIA standards is mounted on the PCMCIA interface unit and then controlling the web browser driving unit so that the driving unit may stand-by the driving of the web browser. Accordingly, it is possible to provide an open cable applying apparatus capable of performing an internet search using a LAN card having PCMCIA standards.

A disk centering apparatus of a compact disk drive including a metal ball having a high moment of inertia and a spring for elastically biasing the metal ball toward the turntable. The ball is disposed in the center of the pulley spindle to prevent pickup errors by reducing the vibration generated during high-speed disk rotation.
