The protrusion 16 is formed on one end face of the ceramic member 11, and the positive electrode lead-out section 13a which is electrically connected to the heat generating member 12 is drawn out and exposed on the side face of the protrusion 16 at several positions, while the terminal 14 of the positive electrode lead-out fixture can be connected to each of the exposed portions. The electromagnet 20 is situated at the rear of the body 10 and a command wiring plane PB is situated at the front of the power wiring plane PA. The bit line air gaps may be formed in the substrate, extending between adjacent active areas of the substrate, as well as above the substrate surface, extending between adjacent columns of non-volatile storage elements. Each cutting element is composed of a plurality of effective cutting faces. Receiving a reply email, wherein the reply email includes the bulk token.
