Abstract: Chewable tablets prepared by incorporating a sugar alcohol with a dissolution endotherm of 20 calories or more per gram of a gastrointestinally active ingredient such as a mucous membrane repairing agent or an antacid are provided. The chewable tablets enable the gastrointestinally active ingredient to be orally administered with ease, without water and free from displeasing intrabuccal sensations characteristic of a gastrointestinally active ingredient.

Abstract: An electric field cancellation apparatus that can reduce electric field radiation from a cathode ray tube inexpensively includes a canceling pulse generating circuit generating a pulse voltage that cancels a leaked electric field radiated from a high voltage generating circuit employed with a deflection circuit or the like. The canceling pulse voltage is superimposed upon an output voltage of the high voltage generating circuit and is applied through an anode to an aperture grill of the cathode ray tube, whereby an electric field having a phase opposite to that of the leaked electric field is radiated from the whole surface of the aperture grill, so that the leaked electric field radiated from the cathode ray tube can be canceled.
