The terminal voltage of the resistor 23 is supplied to a fixed contact of a switch 21 through a preamplifier 24. The switches 5 and 6 are changed over at every field by a field pulse Pf. When a shutter 17 is pushed at a time point TS, the signal of a matrix of one side is ...
A color picture tube which prevents a change in convergence due to current leaked from a resistor during operation of the color picture, thus, providing a stable and satisfactory convergence characteristic in the overall region of the screen. The color picture tube comprises a main electron lens ...
As disclosed in U.S. Pat. No. 3,836,772, motion picture cameras of the type having an automatic focusing device have, until now, been arranged to provide an in-focus signal as a result of a computation based on the outputs of detection arrays, one of which represents a fixed image fo...

Electrospinning is a modern and versatile method of producing nanofibers from polymer solutions or melts by the action of strong electric fields. The complex, multiscale nature of the process hinders its theoretical understanding, especially at the molecular level. The present article aims to contribute...

A current limit fixed resistor 2 connects to each LED 1 and connects to the power supply through a common current adjusting variable resistor 3. Since a positive correlation exists between the radiated quantity of the LED 1 and the supply voltage, the radiated quantity of the LED 1 is ...
PURPOSE:To obtain a concise picture display driving circuit which hardly requires adjustment, by installing a variable resistor for making cut-off adjustment of a color cathode-ray tube to the picture display driving circuit. CONSTITUTION:Color difference signals R-Y, G-Y, and B-Y and a ...
The anode 33 is maintained at a positive potential by means of a source of potential, such as a battery 36, having its negative terminal connected to the cathode 31 and its positive terminal connected to the anode 33 through the resistor 37. The resistor 37 is shunted by a filter ...
