Inventor: WEISELFISH JACOB
IPC: G01D15/24
Filed: 1989-05-19
Abstract: A paper advance control for a progressive x, y plotter with unidirectional paper movement senses (at 64) the actual advancement of the paper and controls the drive to a take-up roll motor 45 in such a way as to keep the speed of advancement constant over the major portion of its advancement. The actual speed is compared at 168 with a reference and any error is used to pulse width modulate the motor drive. The same sensor may also monitor the paper position and stops the paper with accurate positioning at the end of an advancement, its stopping procedure including a slow speed phase before the motor is dynamically braked. The invention is particularly applicable to plotters in which the paper needs to be advanced during the plotting because the plot is wider than a support surface of the plotter. <IMAGE>

Title: Stable PWM control of hydraulic valve - uses FETs as switches to reduce switching delay and increase power efficiency
Inventor: HOENICKE HELMUT PROF DIPL ING
IPC: H01H47/32
Filed: 1989-08-24
Abstract: A stable pulse width modulation electronic driving system for a hydraulic proportioning valve has electromagnets through which current is switched on and off so that the piston is kept in motion by a small vibration power and sudden changes in direction or power are not delayed through inertia or friction. The current is switched by FETs rather than bipolar transistors. The FETs have a high cut-off voltage and high efficiency. Power is dependent only on gate source capacitance. Switching time depends only on capacitance and source and load impedance at the switching instant. The resistance between drain and source is  small. USE/ADVANTAGE - Very efficient. Reduced switching delay without  need for high power. Power needed only on rising and falling edges of pulses. Small drive power; short switching time.
