Title: 外側ビーム間に偏向依存距離を有するカラー表示装置
IPC: H01J29/70
Filed: 2001-11-29
Abstract: カラー表示装置は、電子銃、表示スクリーン、平坦なカラー選択電極及び偏向手段を有する。電子ビーム間の距離を動的に変化させ、これにより、電子ビームを少なくとも１つの方向に偏向させて、偏向空間の距離を減少させる。この距離の減少によって、カラー選択電極と表示スクリーンとの間の距離を前記の方向に増大させることができる。その結果として、カラー選択電極の内面の曲率を増大させることができ、このことによって、カラー選択電極の強度及びドーミング特性に良い影響を与える。このことは、１つの動的電圧を第１及び第２動的電圧電極に印加することによって達成される。

IPC: A23L13/60
Filed: 2002-01-18
Abstract: The invention relates to a method for production of sliced pieces of food, in which a piece of food (3) is cut into slices (8) in a slicer (1) by repetitive cuttings of the piece of food. During the slicing, a preparation inhibiting pathogens (12,16) is being added onto the cut off slice surfaces that occur during the slicing of the piece of food, using one or more noz-zles (9,13). Sufficient amounts of a preparation inhibiting the development of pathogenic germ cells, e.g. listeria organisms, are automatically added onto the surface of the slices. The product thus becomes safe to use after having been stored for a considerable amount of time at fridge temperature.
