<p>PURPOSE:To transmit an information without damaging an airtightness of the container, by constituting a transformer coupling through a wall. CONSTITUTION:In the inside of a wall 4 made of stainless steel, is contained a primary coil 1 being wound on a rod-shape ferrite core 3. In the outside of said wall 4, is wound a secondary coil 2, simultaneously with the outside of the secondary coil 2 covered by a box- shape ferrite core 3. The outside of said ferrite core 3 is covered by a synthetic resin made cover 6, to construct a penetrater 5. By transmitting a plurality of informations with an arrangement of the primary and secondary side coils made to form a transformer coupling through the wall in this way, multiple informations can be transmitted without damaging an airtightness of the container.</p> |
