In an apparatus for manufacturing pressware containers from container blanks there is provided a plurality of inertial blank stop pins disposed so as to position a container blank prior to press forming. The projector can output, so that a computer connected to the projector through a network line can display data relating to the projector, on a monitor screen of the computer, with the same language type as a language type of an OSD menu of the projector, an image data set corresponding to its language type to the network line. Accordingly, a wear amount of contact from the change over time can be obtained. In another aspect of the invention, the invention includes a seat supported on a resilient support frame having a ground engaging portion and an upper portion moveable with respect to the ground engaging portion. The method comprises forming a first insulating layer on a semiconductor substrate; accumulating nitrogen at an interface between the semiconductor substrate and the first insulating layer to form a second insulating layer at the interface; and implanting oxygen into the second insulating layer to convert the second insulating layer to a third insulating layer.
