Title: Switching power supply
Inventor: YASUMURA MASAYUKI
IPC: H02M3/335
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To miniaturize a switching power supply and reduce its weight by varying a switching frequency according to the level of a secondary side DC output voltage and hence compositively controlling the conduction angle between the resonance impedance and the switching element of a primary side parallel resonance circuit, and performing the constant-voltage control of the secondary side output voltage. SOLUTION: Since parts with low breakdown voltage can be used for a switching element Q1, a parallel resonance capacitor Cr, and a secondary side rectification diode, elements can be inexpensive. Therefore, increase in costs needs not be considered especially, and those with improved characteristics (those with improved characteristics of saturation voltage, accumulation time, descent time, current amplification rate, and the like for the switching element Q1 and those with improved characteristics of forward voltage drop, inverse recovery time, and the like for the rectification diode), for example, for the switching element Q1 and the bridge rectification circuit can be selected. By this sort of improvement in characteristics, a switching frequency can be set highly, power loss can be reduced, and each kind of parts can be miniaturized and the weight can be reduced.

Abstract: PURPOSE:To provide a refining method capable of suppressing the formation of Cr oxidation loss at the time of oxygen blowing decarburization and efficiently executing decarburization down to an extra-low carbon region at the time of self-decarburization under a vacuum in decarburization refining of a stainless steel. CONSTITUTION:The basicity (CaO/SiO2) of the slag compsn. of Cr oxide (Cr2O3)- contg. slag is specified to 2.5 to 5 and the Al2O3-contg. concn. thereof to 10 to 20% at the time of executing oxygen blowing decarburization refining of the stainless steel having the Cr-contg. concn. of >=5% in a refining furnace under the atm. pressure or vacuum or at the time of executing reduction refining of Cr2O3 by in-steel carbon by stirring of the molten steel under the high vacuum after stopping of oxygen blowing in the vacuum refining furnace. As a result, the liquid phase rate of the slag is maintained at a high level and the activity of the Cr2O3 in the slag is maintained at a high level. The decarburization reaction is thus accelerated down to the extra-low carbon region without inducing the Cr oxidation.

For the oscillator part 301, projections 302 are arranged alternately at approximately middle positions between the loops and the nodes of the deflection standing wave ingredients. The oscillator part 301, the projections 302, and the oscillator part supporting member 303 may be one body or separate structures, and also as regards the quality of material, they need not be necessarily the same. As above, since the oscillator consisting of the oscillator part 301 and the piezoelectric element 304 is made approximately in the shape of an annulus ring, the reduction of the resonance frequency becomes possible, and the miniaturization and diameter reduction of the oscillator can be materialized.
