Title: Pal luminance signal and chrominance signal separating device
Inventor: NISHIKIORI YOSHIHISA
IPC: H04N9/78
Filed: 1986-07-08
Abstract: PURPOSE:To prevent the degradation of a video signal due to erroneous decision and the increase of the hardwave scale by deciding the correlativity between a sample point to be noticed and a sample point apart by a maximum of one horizontal line period distant from said sample point by a correlativity deciding circuit and smoothing the output from the correlativity deciding circuit in a smoothing circuit. CONSTITUTION:The variance of a color signal before and after one horizontal line period in the vertical direction of the sample point to be noticed is checked by adders 15, 19, and 16. The variance of the color signal at sample points before and after tau=1/4FSC period in the horizontal direction of the sample point to be noticed is checked by an adder 18. Values obtained by weighting absolute values of these variations are used to decide higher one of the correlativity in the vertical direction and the correlativity in the horizontal direction by a correlativity deciding circuit 23 and a smoothing circuit 28. Sample points which are apart only by one horizontal line period from the sample point to be noticed in the horizontal direction and the vertical direction are used to separate a high-band luminance signal by adders 17 and 29. These high-band luminance signal components are selected by a switch circuit 26 based on the correlativity decision result.

Patent JP-H0449851-A (JP)
Title: Driving circuit for dc/dc converter
Inventor: TOMIHARA TOSHIBUMI
IPC: H03K17/687
Filed: 1990-06-19
Abstract: PURPOSE:To reduce a stress of a MOSFET and to reduce noise by lengthening only a delay time of rising times of gate and source voltages of a switching MOSFET. CONSTITUTION:When MOSFETs 1, 4 are simultaneously turned ON, rising delay times of gate and source voltages of the MOSFETs 1, 2 are lengthened by inductances 7, 8. Since the output capacities of the MOSFETs 2, 3 are charged, the peak value of a spikelike current when the drain and source currents of the MOSFETs 1, 4 rise is reduced. When the MOSFETs 1, 4 are simultaneously turned OFF, the inductances 7, 8 are clamped by diodes 5, 6. Accordingly, the delay times of falling gate and source voltages of the MOSFETs 1, 4 are not lengthened, and hence a switching loss is not increased. Thus, a stress to be applied to the MOSFET and noise to be generated can be reduced.
