Abstract: PURPOSE: A method for receiving radio broadcasting signals in cellular phones is provided to perform a receiving standby while radio programs are broadcasted via the cellular phones, and to automatically convert a present mode into a radio mode when a charging is carried out, so that users can obtain a radio device functions through the cellular phones. CONSTITUTION: When radio key signals are received from a key pad(112) or a charging signal is received from a battery circuit(117), a controller(111) connects a voice processor(115) with a radio circuit(118). The controller turns on the radio circuit, to control receiving operations thereof, and outputs control signals to the voice processor. The control signals are for processing a radio signal. The controller controls a radio circuit of a cellular phone to test whether ring signals are terminated. If so, the controller connects a switch to the radio circuit and turns off the radio circuit. The controller transfers control signals of a cellular phone mode to the voice processor, and outputs a ringer tone.

Title: Circuit and method for preventing cell loss of signal in an atm based mobile telecommunication system
Inventor: KWON HEON SANG
IPC: H04L12/28
Filed: 1999-06-24
Abstract: PURPOSE: A circuit and a method for preventing a cell loss in a mobile communication system based on ATM (Asynchronous Transfer Mode) are provided to prevent a cell loss that occurs due to installation and separation of server boards which are built in one backboard. CONSTITUTION: Once boards are installed in a backboard (170), a monitor (140) which monitors the installed boards outputs a low level signal because an edge pin is connected to the ground of the backboard. A counter (120) counts a frame pulse of 125 microseconds generated by a frequency generator (110) 32000 times in response to the output of low level signal. If a counting value reaches a predetermined value, 32000, the counter (120) outputs a counting completion signal of low level to a buffer controller (130). The buffer controller (130) outputs a buffer enable signal to enable input/output buffers (160,150) according to the counting completion signal. Based upon the buffer enable signal, data (or cells) are normally transmitted and received between the backboard (170) and the input/output buffers (160,150). As the output of the buffer controller (130) are full up by resistances (181,182) at ordinary times, enable terminals of the input/output buffers (160,150) are disabled though a power is applied to a board. Therefore, even though invalid data are transmitted to the backboard (170), it can be avoided that the data influence the other boards, and the enable terminal of the input buffer (160) is controlled lest a signal from the backboard (170) should be inputted to a board as well. Consequently, the input/output buffers are controlled not to effect signals set up in the existing boards so that error and loss of data may be prevented. In addition, data loss can be prevented in the case of that boards are only installed in the backboard (170) within a board installation delay time set up beforehand.

Title: Plasma display panel

IPC: H01J11/24
Filed: 1999-06-28
Abstract: PURPOSE: A plasma display panel is provided to improve brightness of a picture by increasing an aperture ratio and generating a discharge only in a display area. CONSTITUTION: X electrodes and Y electrodes are arranged across each other in the order of X1, Y1, Y2, X2, X3, Y3, Y4, X4. A C1 between X1 and Y1 electrodes, a C2 between Y2 and X2 electrodes, a C3 between X3 and Y3 electrodes and a C4 between Y4 and X4 electrodes mean respective display areas. A discharge between X electrode and Y electrode(X1 - Y1, Y2 - X2, X3 - Y3, Y4 - X4) of the display area is generated due to a voltage difference for the discharge of the display area. A voltage difference becomes zero because a voltage pulse of the same phase is applied between Y electrode and - Y electrode(Y1 - Y2, Y3 - Y4) and between X electrode and - X electrode(X2 - X3) of the non-display area. Accordingly, the discharge is not generated in the non-display area regardless of a distance between electrodes of the non-display area.
