Abstract: A bucket that children cannot put over their head, having a bottom wall, side walls, a removable lid and a non-pivoting U-shaped handle. The side walls project upwardly from the bottom wall and form an opening having circumscribing edges. The removable lid fits in the circumscribing edges for closing the bucket. The non-pivoting U-shaped handle has opposite side legs slidably mounted onto the side walls. The U-shaped handle also has stopping means for limiting sliding of the handle between a first position where the U-shaped handle bears against the lid when the same is fitted in the circumscribing edges and a second position where the U-shaped handle extends away from the lid and thus makes it possible to remove the lid from the circumscribing edges. Thus, the U-shaped handle, both in first and second positions, divides the opening into two smaller openings which are smaller than a child's head, thus children cannot put the bucket over their head.

Abstract: A method for fabricating a cylindrical capacitor is provided. This invention uses a composite structure composed of stacked barrier/scarificing/mask layers to prevent the contact plug of the capacitor from being attacked by wet etchants. An insulating layer is formed over a substrate having a source region, a drain region, and a gate electrode. Then a barrier layer, a sacrificing layer and a mask layer are sequentially formed over the insulating layer. Next, a contact hole is formed over the source region and spacers are formed on the sidewalls of the contact hole. After a storage electrode of the capacitor is formed and exposed portions of the mask layer are removed, the sacrificing layer is isotropically etched using the spacers and the barrier layer as stopping layers. Thereafter, a capacitor dielectric layer and an opposite electrode are formed over the storage electrode thereby completing the capacitor.

Abstract: This invention relates to a method for measuring the electrode-related electric quantities of an AC electric-arc furnace. The method is based on observing the mutual correlation between electrode currents and total power supplied into a furnace by utilizing the fast, natural fluctuation of currents and power supplies into a furnace, and on estimation observations. The information required in estimation is collected by performing a plurality of successive current and voltage measurements at adjacent instants and at various energy distributions of a furnace. The measurement results are used to calculably determine the estimates for electrode-related voltages, impedances and powers. It is further possible to split the electrode-related powers and voltages on the one hand in the electric-arc power and voltage and on the other hand in the power and voltage loss caused by resistive conduction. The effect of mutual impedances is automatically taken into account in estimation.
