Abstract: PURPOSE: A method for multiplexing various channels of a low transfer rate at a high transfer rate is provided to extract a frame of 2048Kbps by dividing each channel into basic channels and using each basic channel as the input of a multiplexer. CONSTITUTION: If a channel is inputted, a multiplexer confirms the coding method and speed of the inputted channel. The multiplexer judges whether the channel uses a CRC(Cyclic Redundancy Check) method as a frame error correction method(1101). If the channel uses the CRC method, the multiplexer checks the channel as "110" to indicate that it is a 64Kbps channel using a PCM coding method(1102,1103). The multiplexer divides the channel into four 2-bit basic channels(Bc1/4 to Bc4/4)(1104). The multiplexer allocates the four basic channels to a time slot(1105). The multiplexer appoints signaling information to the 16th time slot(1106). Then the multiplexer confirms whether the configuration of one multiframe has been completed(1107).

Abstract: PURPOSE: A device for limiting operating height of a mast and traveling speed of a forklift is provided to make height of a lift uniform and to perform work easily by fixing an approximate sensor in a specific position and controlling operation of a hydraulic motor corresponding to the operation of the approximate sensor when articles are loaded or unloaded. CONSTITUTION: An approximate sensor(42) is placed in one groove formed in one end of an outer mast to sense approach of an inner mast. A control unit(41) outputs a signal for limiting traveling speed of a drive motor and height of a mast. Upon detection of the approaching inner mast, operation of a limit function switch(S3) is decided. If the limit function switch is turned on, the control unit limits lifting height of the mast. If a limit switch(S2) is operated, the control unit drives a hydraulic motor by applying a PWM(Pulse Width Modulation) pulse to hydraulic motor driving transistors(HTR). If a lift lever is pulled rearwardly, compressed oil is supplied to the bottom of a lift cylinder and the lift cylinder is lifted up. Thus, a carriage stand is lifted upwardly. If the approximate sensor is turned off, the control unit stops application of PWM pulse to the hydraulic motor. Then, the hydraulic motor is stopped. Thereafter, the control unit decides if a forklift car travels. If the car travels, speed of a drive motor(44) is limited based on a reference duty up to a speed limit. When the approximate sensor is placed in a high position, 50% of the maximum duty is outputted. 70% of the maximum duty is outputted when the approximate sensor is placed in an intermediate position. In a low position, 90% of the maximum duty is outputted.
