Title: Ferrite magnetic core
Inventor: TANAKA YOICHI
IPC: H01F27/24
Filed: 1991-04-30
Abstract: PURPOSE:To reduce a leakage magnetic flux, by making one of both magnetic cores placed in a butted part a protruded part and making the other magnetic core a recessed part, and by inserting the protruded part into the recessed part, and by providing tapered surfaces on the protruded and recessed part, and further, by changing the angle which both the tapered surfaces form with each other or changing the curvatures of both the protruded and recessed part. CONSTITUTION:A ferrite magnetic core comprises two E-shaped ferrite magnetic cores 1, 2, whose central legs 3, 4 are both cylindrical. The end of one of the central legs is made to take a recessed form, and the end of the other central leg is made to take a protruded form. The ends of the central legs 3, 4 are made to have curved surfaces whose curvatures are different from each other. The center part of the end of the central leg 4 is in contact with the central leg 3. The space between both the curved surfaces is so formed as to increase gradually as proceeding from the center part to their peripheral parts. Further, in the gap part between both the curved surfaces, the central leg 4 is inserted into the central leg 3, and therefore, the leakage magnetic flux of the ferrite magnetic core is made less. Also, by changing the area of the contact part, or by changing the angle which both the tapered surfaces form with each other, or by changing the curvatures of both the curved surfaces, the adjustment of a DC superposition characteristic is made possible, and the desired DC superposition characteristic, such as a nonlinear one, can be obtained.

Abstract: PURPOSE:To enable the checking for a disconnection in a circuit to be measured and an internal power source circuit of a C-MOSIC, by changing internal logic state of a C-MOS to make transistors of both a N-channel and a P-channel conductive simultaneously. CONSTITUTION:The level of a power source 4 is set to a half as much as the level of a power source 3. At this point, in a C-MOSIC 1, transistors of a P- channel and a N-channel are made to conduct inside and current flows from a positive poler terminal of the power source 3 to the IC 1, an ammeter 2 and a negative poler terminal of the power source 3. Reference values of the currents are determined beforehand based on data obtained by measuring samples taken from C-MOSICs typewise. After the measurement of the current of the power source, the level of the power source 4 is set down to zero or the same level as the power source 3 to allow the interruption of the N-channel transistor or the P-channel transistor. Thus, the measurement of a leakage current can be made by reading the current value of current with the ammeter 2.

Abstract: PURPOSE:To refine very low carbon steel by a VAD furnace only, by heating molten steel in a pressure-reduced state, and blowing oxygen toward the surface of the molten steel in a ladle through an oxygen lance which has been made to pass through the side wall of a vacuum vessel. CONSTITUTION:The inside of a vacuum vessel 1 is held in a pressure-reduced state, the inside of molten steel 5 is bubbled by blowing in inert gas 7 such as Ar or N2, etc. from the lower part of a ladle 2, and an arc is generated through an electrode 3, by which the molten steel 5 is heated. On the orther hand, decarburization is executed by blowing oxygen toward the surface of the molten steel 5 from an oxygen lance 8 inclined through the side wall of the vessel 1. When blowing of oxygen is unnecessary, for instance, at the time of heating, the lance 8 is moved backward. The lance 8 is burned out when it is used for a long period of time, therefore, it is advanced by that portion. Also, according to this method, it is also possible to execute a dephosphorization treatment. In this case, a slag for dephosphorization is thrown into the molten steel 5 through a slag throw-in hopper 6, and oxygen blow-refining is executed.
