摘要： The present invention relates to a cutting tool capable of both drilling and internal/external turning. The cutting tool comprises a generally triangular-shaped cutting insert and a tool holder. On each side, the triangular-shaped cutting insert forms a major cutting edge and a minor cutting edge, which is shorter than said major cutting edge. Two adjacent major cutting edges form an angle of 60° therebetween, while adjacent major and minor cutting edges intersecting at a corner of the triangular shape of the cutting insert form an angle of 80 to 89° therebetween. The cutting insert is mounted in a pocket so that one of the major cutting edges of the cutting insert is projected in an axially forward direction of the tool holder, while the minor cutting edge on the side adjacent to the projected major cutting edge is projected in a radially outward direction of the tool holder.

摘要： A ferroelectric recording medium and a writing method for the same are provided. The ferroelectric recording medium includes a ferroelectric layer which reverses its polarization when receiving a predetermined coercive voltage. A nonvolatile anisotrophic conduction layer is formed on the ferroelectric layer. A resistance of the anisotrophic conduction layer decreases when receiving a first voltage lower than the coercive voltage, and the resistance of the anisotrophic conduction layer increases when receiving a second voltage higher than the coercive voltage. Multi-bit information is stored by a combination of polarization states of the ferroelectric layer and the resistance of the anisotrophic conduction layer. Accordingly, multiple bits can be expressed on one domain of the ferroelectric recording medium.
