When conducting encryption key update, each of the network device successively causes transition among an initial state in which only data encrypted using an old encryption key used before the update can be transmitted and received, a state in which both data encrypted using the old encryption key and data encrypted using a new encryption key used after the update can be transmitted and received, but operation concerning transmission and reception of data encrypted using the new encryption key is not confirmed, a state in which both data encrypted using the old encryption key and data encrypted using the new encryption key can be transmitted and received, and operation concerning transmission and reception of data encrypted using the new encryption key is already also confirmed, and a final state in which only data encrypted using the new encryption key can be transmitted and received. The encryption key is thus updated.

A process for producing a sintered thermoelectric semiconductor includes a first step of forming bulk crystals of a thermoelectric semiconductor and a second step of hot extrusion. The second step includes substeps of placing the bulk crystals in the cavity of a heated extrusion die, pushing the ram into the cavity, thereby compressing and crushing the bulk crystals and turning them into a molten or semi-molten state, and finally extruding the molten or semi-molten crystals, thereby sintering them and forming a sintered thermoelectric semiconductor.

A method for producing a thermoelectric semiconductor includes an ingot production step for producing an ingot of a thermoelectric semiconductor and an integrating step for integrating a plurality of the ingots by plastic deforming the ingots to produce an integrated ingot of the thermoelectric semiconductor. The large size of the thermoelectric semiconductor ingot having uniform performance and mechanical strength can be produced by integration of two or more ingots. Therefore, many wafers can be produce at one time in the slicing step, and productivity is improved. Further, two or more ingots are integrated by plastic deformation so that the connecting strength of the connecting interface is strong.

An displacement correcting device is provided and includes: a rotation supporting member having a rotation shaft and rotating to support the endless belt-shaped member; a shaft supporting frame supporting a one-end supporting portion of the rotation shaft movably relative to an opposite-end supporting portion and supporting one end of the rotation shaft to be tilted about the other end; and a shaft displacing member having a rotation center disposed closer to one end portion in the axial direction than a rotation shaft supporting body and intersected by the axial direction and a rotation shaft contact portion contacting with the one end of the rotation shaft. The shaft displacing member allows the rotation shaft contact portion to rotate about the rotation center to tilt the rotation shaft when a movement sensing member detects the movement of the endless belt-shaped member to the one end of the rotation shaft.
