| 摘要 | PURPOSE:To miniaturize the whole size and to elevate the mass productivity and the ecomony of the oscillation transformer for flasher by a method wherein the height is made to be lower and the volume is made to be smaller, and the construction of core is simplified. CONSTITUTION:The primary winding 11c consisted of a conductor having the diameter of about 0.4mm. is wound about six times around a winding part 11b1 of a bobbin 11b of the oscillation transformer 11, and the secondary winding consisted of a conductor having the diameter of about 0.04mm. is wound around about 800 times at the inside of the winding 11c. A core 11a is consisted of an E-shaped core 11a, and a flat plate core 11a2. By this way, the whole height is formed to be about 7mm., the length of one side to be about 10mm. and the breadth of core to be about 4.8mm.. By turning a power switch 12 to ON side, a capacitor 16 is made to be changed with the charge from a source 13 through a resistor 14 and a feedback winding 11c, and an oscillation transistor Tr15 is made to be ON state by the application of voltage to the Tr to make a current to flow through the winding 11c. By this current, the voltage of 350V is induced in a winding 11f, and a current also flows in a winding 11e to continue the oscillation. | ||||||
