Title: Method for compressing and transmitting data between mobile terminal and base station in mobile telecommunication system
Inventor: HEO CHEOL GYUN
IPC: H03M7/30
Filed: 1998-08-17
Abstract: PURPOSE: A method for compressing and transmitting data between a mobile terminal and a base station in a mobile telecommunication system is provided to improve data transmission rate between a mobile terminal and a base station/mobile switch center. CONSTITUTION: In a compression mode, a frame transmitted from a transmitter is compressed in an encoder. If the compressed frame is received, the encoder sets a last_frame_timer T1 and stores a received data frame to a frame buffer. Thereafter, it is determined whether data capacitance stored in the frame buffer reaches maximum limitation. If the data capacitance does not reach the maximum limitation, the encoder sets total_timer while when the data capacitance has been reached the maximum limitation, the encoder compresses the stored data and transmits the compressed data. The set last_frame_timer and the total_timer are ended, a size of data stored in the frame buffer is compared with that of a compression level indicator(CL1). When the size of data stored in the frame buffer is greater than that of the compression level indicator, the data is compressed and is then transmitted.

Title: Method for controlling pump according to state of system in gas boiler
Inventor: KIM CHANG YEON
IPC: F24H9/20
Filed: 1998-12-23
Abstract: PURPOSE: A method for controlling pump according to state of system in gas boiler is provided to increase heating efficiency, extend running life of a boiler, and improve consumer's satisfaction by automatically detecting a revolution speed of a fan in a gas boiler and a difference value between an outlet temperature of heating water and an inlet temperature of heating water flowing back and then controlling the speed of a circulating pump to control the circulating amount of heating water. CONSTITUTION: In a method for controlling pump according to state of system in gas boiler, when an operating system in a gas boiler is turned on and then starts to operate(S1), a detection whether the revolution frequency(FG) of a fan being operated is higher or not than a predetermined minimum revolution frequency value(Arpm) set previously is performed(S3). If the revolution frequency(FG) is higher than the minimum revolution frequency value(Arpm), a circulating pump is operated(S4). If the revolution frequency(FG) is lower than the minimum revolution frequency value(Arpm), abnormal state is displayed to a user at an error mode(S30). Then, a detection whether the revolution frequency(VH) of the circulating pump being operated(S4) is higher or not than a predetermined minimum revolution frequency value(Krpm) set previously is performed(S5). If the revolution frequency(VH) is higher than the minimum revolution frequency value(Krpm), a proportion valve supplying gas to a gas burner regulates the amount of gas(S61) in proportion to the revolution frequency of the fan to make a normal combustion operation to be carried out based on a temperature difference(delta t) between thermistors(TH1 and TH2)(S6). If the revolution frequency(VH) is lower than the minimum revolution frequency value(Krpm), a microcomputer controlling the system determines that the circulating pump is not rotated and then displays abnormal state to a user at error mode(S30). At that time, a measurement of the revolution frequency(FG) is carried out(S7). If the revolution frequency is detected as being in a range(Arpm≤FG≤Brpm)(S8), the circulating pump is operated under low speed(S9). If the revolution frequency is detected as being in a range(Brpm≤FG≤Crpm)(S10), the circulating pump is operated under middle speed(S11). If the frequency is detected as being in a range(Crpm≤FG≤Drpm)(S12), the circulating pump is operated under high speed(S13).

Title: Interlock device for preventing backup mis-operation of manual transmission vehicle
Inventor: KIM SEOK U
IPC: B60K17/06
Filed: 1998-12-30
Abstract: PURPOSE: An interlock device for preventing backup misoperation of a manual transmission vehicle is provided to prevent misoperation to shift to a backup stage. CONSTITUTION: When a driver misoperates a shift lever while shifting to a fourth stage from a fifth stage or shifts a gear to the direction for shifting to a backup gear due to misunderstanding, a shift fork(20) is moved to the right and hung on an interlock pin(13) of an interlocker. An inclined face of the shift fork bumps against an inclined face of the interlock pin. The shift lever is operated by the force stronger than the stretching force of an interlock spring(12) thus shifting to a backup gear is not performed until the shift fork is not shifted. Thereby, the driver senses the load given to the operation of the shift lever while operating the shift lever by a general force needed for operating a shift lever.
