Title: Switching power supply
Inventor: OKADA TETSUYA
IPC: H02M7/12
Filed: 1990-03-14
Abstract: PURPOSE:To sustain feedback operation by feeding the output from an auxiliary winding directly to a photocoupler when the secondary (load) voltage of a switching transformer drops to a level at which a feedback control circuit is disabled. CONSTITUTION:An AC voltage is transformed 2 and rectified 3 to produce a DC voltage which is then switched through a FET 9 thus inducing a high frequency voltage in a feedback winding 6, a secondary winding 7 and an auxiliary winding 8 through the primary winding 5 of a transformer 4. Output voltage of the secondary winding 7 is set higher than the threshold of a Zener diode 19 and a transistor Tr 18 is normally turned ON. When the output voltage of the secondary winding 7 drops due to fault, a feedback control circuit 14 is disabled but the Tr 18 is turned OFF and the output voltage of the auxiliary winding 18 directly energizes the LED 16 in a photocoupler 15. Consequently, feedback operation is sustained and an oscillation control circuit 10 decreases the output voltage of an inverter transformer 4. Since a large current is suppressed on the primary and secondary, circuit elements are protected against breakdown.

Abstract: PURPOSE:To provide a cam shaft provided with a surface layer having a lower layer of high strength. CONSTITUTION:The cam shaft 1 is provided with a base metal made of cast iron and a surface layer 4 formed on the outer circumferential face of a journal part 3 of the base metal and having a bearing member 5 and a sliding face 4a. The surface layer 4 is formed by Fe electroplating and is constituted of a lower layer 41 closely stuck to the journal part 3 and an upper layer 42 closely stuck to the lower layer 41. The lower layer 41 is constituted of an aggregate of Fe crystals having a body-centered cubic structure. This aggregate contains, by the Miller index, {211}-oriented Fe crystals in which the {211} plane is oriented to the side 4a of the sliding face. The abundance ratio S of the {211}- oriented Fe crystals is regulated to >=30%. Since the {211} plane is a secondary plane, the {211}-oriented Fe crystals have high hardness, and in the case of setting the abundance ratio S >=30% the strength of the lower layer 41 is made high, so that the generation of cracks in the vicinity of the base metal of the surface layer 4 can be evaded.
