摘要： A synchronized chaotic system and a communication system using the synchronized chaotic system is disclosed. The synchronized chaotic system comprises a master chaotic part and a slave chaotic part, and a synchronizing part. The synchronizing part preforms operational functions to synchronize a chaotic signal output of the master chaotic part with a chaotic signal output of the slave chaotic part. The synchronizing part for preforming the operational functions includes a subtractor, scaler, and an adder. The output of the adder is is feedbacked to the slave chaotic part. The synchronization occurs when the synchronized system consisting of the variable differences of the master and the slave chaotic parts generates infinite period of laminar phase which is connected with on-off intermittency. Also, the synchronized chaotic system is applied to a communication system for encryption. The communication system comprises a transmitter including a master part for producing a chaotic signal and an adder for adding message signal to the chaotic signal, and a receiver including a slave part for producing a chaotic signal and a synchronizing part for synchronizing the chaotic signal of the master part with the chaotic signal of the slave part to retrieve the message signal.

摘要： A fuel tank mount for forklift trucks is adapted to hold a fuel tank over the top of a counterweight in a manner that the tank may be easily lifted up and lowered down. The fuel tank mount includes a swing arm replaceably carrying the fuel tank and mounted to the counterweight for swinging movement about a tilted pivot axis between a home position wherein the fuel tank is held over and laterally across the counterweight, a neutral position wherein the fuel tank remains at its highest elevation and a tank changing position wherein the fuel tank is oriented substantially vertically. The pivot axis remains tilted both forwards at a first tilt angle, e.g., 26 degrees, and outboards at a second tilt angle, e.g., 25 degrees, with respect to a vertical axis. A latch is provided to keep the swing arm in the home position against unwanted swinging movement into the neutral and the tank changing positions. The motion of the swing arm is damped by dint of an extension spring and an extension damper to help the operator lift the fuel tank.

The reach leg has a guide rail fixedly attached thereto and provided with a vertical wall, a top flange and a bottom flange cooperating together to define a guide groove. A mast assembly with a base is supported on the reach leg and movable along the guide rail toward and away from the vehicle body. Front and rear support rollers are rotatably attached to the base of the mast assembly in a spaced apart relationship with each other and received in the guide groove of the guide rail. A front vertical clearance compensator is mounted to the mast base adjacent the front support roller for making contact with the underneath surface of the top flange of the guide rail, while a rear vertical clearance compensator is similarly provided adjacent the rear support roller for making contact with the top surface of the bottom flange of the guide rail. A lateral clearace compensator may be further employed to reduce the transverse jerking motion of the mast assembly.

摘要： A synchronized chaotic system and a communication system using the synchronized chaotic system is disclosed. The synchronized chaotic system comprises a master chaotic part and a slave chaotic part, and a first synchronizing part connected to the master chaotic part and a second synchronizing part connected to the slave chaotic part. The first and second synchronizing parts preform operational functions to synchronize a chaotic signal output of the master chaotic part with a chaotic signal output of the slave chaotic part. Each of the first and second synchronizing parts includes a first scaler, a subtracter, a second scaler, and an adder. Each output of the adder is fed back to the main and slave chaotic parts. The synchronization occurs when the synchronized system consisting of the variable differences of the master and the slave chaotic parts generates infinite period of laminar phase which is connected with on-off intermittency. Also, the synchronized chaotic system is applied to a communication system for encryption. The communication system comprises a transmitter including the master part and the first synchronizing part and further including an adder to hide message signals in the chaotic signal, and a receiver including the slave part and the second synchronizing part and further including a subtracter to retrieve the message signal from the mixed signal.

摘要： A pump motor control apparatus is adapted to control a pump motor of a forklift truck by using a driving transistor connected between a battery and the pump motor. The pump motor control apparatus includes a current detection circuit for detecting a current flowing through the pump motor to generate a current detection signal representing the current. A controller is employed to determine the load condition based on the current detection signal to thereby generate a control signal for use in the control of the driving transistor. The control signal is a pulse width modulation signal whose on-duty ratio is controlled depending on the load condition so as to decrease the torque and speed of the pump motor during the unloaded condition but to increase the torque and speed of the pump motor during the loaded condition.
