Title: Switching control type power source circuit
Inventor: OKADA YUKIO
IPC: H02M3/338
Filed: 1984-04-27
Abstract: PURPOSE:To improve the load regulation by connecting a resistor in series with a feedback winding and obtaining a CD voltage through the resistor. CONSTITUTION:A switching control type power source has an input rectifier 1, a blocking oscillator 2, a converter transformer 3, an error detector 4, a controller 5, and an output rectifier 6, a positive feedback current If is supplied from a feedback winding NB through a base current limiter SK to the base of a transistor TR4 to perform a blocking oscillation in the oscillator 2, and controlled in response to the output of the detector 4. In this case, a resistor R16 is inserted in series between (e) terminal of the winding NB and a diode D6. Thus, if the output current of the output winding N2 increases, the induced voltage to the winding NB increases, but the rise of the detected voltage stored in the capacitor C3 is suppressed by rectifying via the diode D6 due to the voltage drop of the resistor R16, and the ON period of the switching transistor Tr4 is increased.

Title: Production of alloyed galvanized steel
Inventor: SAORI TAKASHI
IPC: C23C28/00
Filed: 1991-03-28
Abstract: PURPOSE:To form an alloyed galvanized layer excellent in surface properties and adhesion, at the time of subjecting a galvanized layer to alloying treatment, by regulating the reaction rate of allaying by an Fe-B preplated layer. CONSTITUTION:An Fe-B preplated layer is preliminarily formed on the surface of a steel strip to be plated. After that, the steel strip to be plated is passed through a hot dip zinc bath to regulate the coating weight of hot dip zinc on each face, and then, allaying treatment is performed. The preplated layer is formed by 1 to 20g/m<2> coating weight by electroplating, strike plating or the like. Because the Fe-B preplated layer promotes the alloying without the influence of the degenerated surface layer of the steel to be plated, the sheet passing rate can be raised to increase its productivity. Furthermore, in accordance with the reduction of the alloying treatment time, the growth of a brittle philayer can be suppressed.
