A mold used to form a latex lid for covering a beverage cup includes a body having a top forming face and a side forming face extending around and turning downward from the top forming face, a stubby projection which has a rounded surface, provided on the top forming face, a shallow recessed fink provided in the top forming face around the stubbing projection. In forming the latex lid, the stubby projection creates a thinned area in the latex lid which facilitates the insertion of a straw, and t…

In a rotary nozzle of the type attached to the bottom shell of a molten street vessel and designed so that a rotor having a sliding plate brick mounted thereon is rotated by a motor through a reducer and gearing to adjust the degree of opening of a nozzle bore and thereby to control the pouring rate of molten steel, the rotation of the rotor is effected by hydraulic cylinders in place of the reducer, gearing and motor. Thus, there is the effect of providing a rotary nozzle which is small in size…

A doping method using an oxide film and a nitride film on a trench wall as a protective film to prevent the impurity from diffusing into the silicon wafer adjacent to the outer wall and to enable the formation of a substantially flat interface between the first and the second trench to provide a smooth step difference between the first trench and the second trench is disclosed. A highly integrated semiconductor device having a trench comprising a first trench having a bottom and with a second tr…
