Title: Resonant converter
Inventor: ONDA KENICHI
IPC: H02M3/28
Filed: 1987-09-09
Abstract: PURPOSE:To ensure the initiation of oscillation, by providing a shortpreventive switching elements and an oscillation prevention circuit on the secondary side of a transformer. CONSTITUTION:A resonant converter is composed of switching elements M1-M2, a resonance circuit 1 made up of a transformer T, etc., a short-prevention circuit 2, an oscillation prevention circuit 3, a self-exciting oscillation circuit 4, a smoothing circuit 5, a fullwave rectification circuit 6, etc. If the secondary winding of the transformer T is brought into a short-circuit state, then the resonance current flowing to the secondary winding of the transformer T will flow to the secondary winding side where the winding becomes short and no voltage will be induced to each winding of the transformer T. On this account, no voltage can be applied any longer to control electrode of switching elements M1 and M2 from a winding Ns for self-exciting oscillation and oscillating operation will stop. In addition, the short-prevention circuit 2 prevents the secondary winding from getting to be shorted and the resonance current from flowing to the secondary winding side.

During said blowing, when the inert gas or a hydrocarbonic gas is blown in, solidified iron is formed around the tuyere, and the tuyere is clogged in time according to circumstances. The clogging is detected, for example, by the detecting end 6 of gas pressure, and an oxidative gas is mixed into a tuyere protective gas which is being supplied into the passage in the clearance between the inner and the outer pipe in accordance with the detected result. Consequently, an exothermic reaction is initiated between said gas and solidified iron or an oxidative component, and the solidified iron can be melted.

Title: Call signal detecting circuit
Inventor: KAGAWA MASATO
IPC: H04Q3/42
Filed: 1990-08-28
Abstract: PURPOSE:To prevent an erroneous operation surely by detecting a call signal in the serial circuit of a constant voltage diode, a photocoupler, a resistor and a capacitor, and outputting a detecting signal through a delay circuit. CONSTITUTION:The forward current of the call signal whose direction changes alternately flowing in a photocoupler 6 is generated by a remaining voltage except for a voltage value specified by a constant voltage diode 5, and a noise voltage and the like causing the erroneous operation are suppressed. An inverse current to the photocoupler 6 flows in a diode 8, not in the photocoupler 6. The call signal detected in the photocoupler 6 can remove the noise whose voltage is high but a duration is short by outputting after the lapse of a specified time in a delay circuit 9. After that, the detecting signal can avoid an influence to the delay circuit 9 from a device in a back position by outputting through a photocoupler 10 as an output signal 11.
