Abstract: Video  signal  color  correction is accomplished by selecting   for   color   correction   areas   of   the chrominance    plane    defining   sectors   in   polar coordinants.    Both  the  angle  and  the width of the sector  can  be changed to select precisely the desired signals  for color correction.  Specifically, component color  difference video signals which only lie within a fixed  hue  sector  are transmitted from an input to an output.    Responsive  to  a  first control signal, the difference  signals  are rotated through an angle which corresponds  to  a  selected hue sector relative to the fixed  hue  sector in which the component color signals are  to  be  corrected.  The rotated difference signals are  applied  to  the input to produce at the output an isolated  color signal only when the difference signals lie  within  the selected hue sector.  The width of the fixed  hue  sector  is  reduced  responsive to a second control  signal.    Thus,  the first and second control signals  permit selection of the angle and the width of the  sector  in  which the difference signals are to be corrected.

Abstract: ELECTRONIC CONTROL SYSTEM FOR POWERSHIFT TRANSMISSION                      ABSTRACT OF THE DISCLOSURE                   A microprocessor-based electronic control system for a powershift transmission having at least one proportional actuator, such as a solenoid-operated proportional valve, is disclosed. The controller operates a plurality of on-off solenoid valves and the solenoid-operated proportional valve to provide operator-selected gear shifts in both forward and reverse directions having controlled clutch engagements achieved by modulation of clutch engagement pressure by the proportional valve. The key parameters associated with the gradual clutch engagement are all easily varied by the controller, most under program control during operation, to provide for optimized clutch engagements for smooth gearshifts. The key parameters include: fast-fill clutch delay, initial clutch engagement pressure, rate of increase of clutch engagement pressure, and the length of the reduced pressure clutch engagement interval. The electronic controller also automatically modifies selected parameters in accordance with sensed changes in temperature, magnetic flux coupling between solenoids, and variations in the voltage supply provided to the series combination of the solenoid coil of proportional valve and its solenoid driver circuit. Preferred methods of operating the electronic controller and powershift transmission are also disclosed.

Title: Frequency-dividing circuit
Inventor: TANAKA KOUTAROU
IPC: H03K3/037
Filed: 1989-02-06
Granted: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSURE      In a frequency-dividing circuit for producing an output having a frequency half that of its input,  a pair of terminals of a latch circuit are connected to input terminals of a pair of delay means  and are also connected to receive through a pair of transistors  the outputs of the delay means.  A single-phase input signal is input to the control electrodes of the transistors to turn on and off the transistors.  When the transistors are turned from off to on  the output states of the delay means are transferred through the transistors to invert the latch circuit, and the states of complementary terminals of the latch circuits are in turn transferred through the delay means to invert the output states of the outputs of the delay means.  When the transistors are turned from on to off, no change occurs in the states of the circuit.  In this way  the states of the circuit are inverted each time the transistors are turned from off to on.  A frequency-divided output can therefore be derived at one of the outputs of the first and second delay means.  Either one or both of the first and second inverters may be replaced by a NAND gate or a NOR gate for permitting reset of the circuit.
