Title: Analog-digital converter for video signal
Inventor: MATSUMOTO SHIYUUZOU
IPC: H03M1/36
Filed: 1982-06-28
Abstract: PURPOSE:To attain economization and miniaturization, by constituting an A/D converter with comparators operating by single power supply. CONSTITUTION:When a video signal is applied to an input terminal 5, a switch 9 is closed by the time of synchronizing part of the signal and a capacitor 10 is charged with a bias voltage source 8. As a result, the video input signal clamped with a voltage of the bias voltage source 8 and a reference voltage superimposed with the voltage of the bias voltage source 8 are inputted to the comparators 31-3n. Since the bias voltage acts like in-phase to both the inputs, the voltage gives no effect on the comparing operation but gives a bias voltage to the comparators 31-3n. Thus, the comparators 31-3n perform normal comparing operation by connecting a terminal 7 to ground and a positive single power supply to a terminal 6, respectively.

IPC: H01F1/16
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To reduce high frequency loss by controlling the magnetic permeability at the surface of a sheet to equal to or above specified times of the magnetic permeability at the middle part of the sheet. SOLUTION: The magnetic permeability at the surface of the sheet is controlled to >=2 times of the magnetic permeability at the center part of the sheet. Preferably the magnetic permeability at the surface of the soft magnetic sheet composed of a silicon steel plate having Si concentration gradient in the thickness direction is >=2 times of the magnetic permeability at the center part of the sheet and <=3.5% Si is contained in the whole thickness of the steel plate on an average. Further, the thickness of high magnetic permeability part from the surface is desirably >=5% of the plate thickness. As a result, for example, the loss of a 6.5 wt.% Si-containing homogeneous material (the quantity of Si is 6.5 wt.% through whole thickness) of a Fe-Si alloy sheet, which has most excellent soft magnetic property, enables to be reduced by max. 30% in this new magnetic sheet.  The soft magnetic sheet low in high frequency iron loss, which is suitable for a core of a transformer, a reactor, a motor or the like, is obtained without deteriorating machinability and decreasing the sheet thickness.
