Abstract: A controlled-punch-through semiconductor device with a four-layer structure is disclosed which includes layers of different conductivity types, a collector on a collector side, and an emitter on an emitter side which lies opposite the collector side. The semiconductor device can be produced by a method performed in the following order: producing layers on the emitter side of wafer of a first conductivity type; thinning the wafer on a second side; applying particles of the first conductivity type to the wafer on the collector side for forming a first buffer layer having a first peak doping concentration in a first depth, which is higher than doping of the wafer; applying particles of a second conductivity type to the wafer on the second side for forming a collector layer on the collector side; and forming a collector metallization on the second side.

Abstract: A bag tossing game including a pair of boards each having opposing top and bottom surfaces. Each of the boards has an opening extending from the top surface to the bottom surface. Each of the boards includes a pair of opposing ends and a pair of opposing sides extending between the opposing ends and formed by a rim projecting from the bottom surface. At least one riser is pivotally coupled to one end of each of the boards. A storage pouch is coupled to the bottom surface of one of the boards. The pouch encloses an interior storage space and has an opening in communication with the interior space. The pouch has a closure mechanism for closing the opening. The game also includes a hook and loop fastener releasably coupling the pair of boards to one another. A handle is coupled to at least one of the opposing sides.

Abstract: A basketball rim assembly includes an anchoring plate having a mounting assembly, a back plate, a support member, a rim and a locking mechanism. The anchoring plate is removably attached to the back plate by the mounting assembly, and the locking mechanism, comprising of a cam assembly, locks the back plate to the anchoring plate allowing for the safe and easy removal and placement of the rim.

Abstract: The present invention relates to a video game control arrangement in which player movement is controlled on a video screen from the handlebars of an exercise device such as a stationary exercise bicycle. The arrangement is set up such that the video controls can only be operated with a pre-set acceptable exercise level below which the controls are non-operational.
