Abstract: The invention relates to a hockey puck with a flat cylindrical body (1) of flexible elastic material. The aim of the invention is to provide a puck which is particularly suitable for playing hockey on hall floors or in the street and is as visible as possible during the game. This aim is attained in that the flat cylindrical body (1) consits of several disc-shaped segments (2, 3, 4) firmly bonded together, where a central segment (3) is made of a transparent material and has a recess for an insert with a light source (5, 6), a power source (7), a switch (8) and regulating and control components.

Abstract: A first driver MOS transistor and a second driver MOS transistor are formed at the surface of a semiconductor substrate. A first load element is connected to the drain region of the first driver MOS transistor and the gate electrode of the second driver MOS transistor. A second load element is connected to the drain region of the second driver MOS transistor and the gate electrode of the first driver MOS transistor. A first transfer MOS transistor is formed at the surface, one of the source and drain regions of which is connected to the drain region of the first driver MOS transistor. Further, a second transfer MOS transistor is formed at the surface, one of the source and drain regions of which is connected to the drain region of the second driver MOS transistor. An inter-layer insulation film is formed on the first driver MOS transistor, the second driver MOS transistor, the first transfer MOS transistor and the second transfer MOS transistor.

Abstract: A semiconductor device has formed onto the surface of a collector region 12 of a semiconductor substrate 11 of one conductivity type with a base region 13 of a different conductivity type, an emitter region 16 of the one conductivity type formed on a surface within the base region 13, and a base electrode 18 and emitter electrode 17 which are formed by opening windows in the base and emitter regions 13, 16.
