A nonvolatile semiconductor memory is disclosed. The reinforcement layer first portion envelopes the core first portion. A physical gap is disposed in the core’s magnetic path. A gateway between the local area network and the exterior may be tasked with this selective transformation of the mode of transmission of the streams received. The sliding mechanism includes an intermediate stopper mechanism that can be operated to switch between a state where the cutting machine body can slide within an entire slidable range and a state were the cutting machine body can slide only within a partial slidable range at a midway position. The supporting structure has an attachment fixable to the fuselage, and a first and a second beam having first connecting portions hinged about a first axis to each other and to a top end portion of the shock absorbing member.
