摘要： A data processor capable of executing sequential processing efficiently while retaining the advantages of a prior art data-driven processor. The data processor includes: an instruction fetch unit which fetches a data-driven instruction or a control-driven instruction from an instruction memory based on an input packet or a program counter; an instruction decode unit which decodes the issued instruction and, in the case of the control-driven instruction, thereafter accesses a register and performs register renaming if a data hazard is detected; a firing control unit which stores the decoded instruction in a matching memory to wait therein, and which selects one of the ready-to-fire instructions and fires the selected instruction; an execution unit which performs an operation specified by the fired instruction and, in the case of the data-driven instruction, transfers an operation result to the instruction fetch unit, or in the case of the control-driven instruction, forwards the operation result to the firing control unit; and a write back unit which writes the operation result to a register.

摘要： A magnetic head slider (1) has a first rail (20) with a first air bearing surface, a second rail (25) with a second air bearing surface and further a third rail (15) with a third air bearing surface. The third rail is formed between the first rail (20) and the second rail (25). On both sides of the third air bearing surface (16), a first air pressurization part (17) and a second air pressurization part (18) are formed sunk by respective depths. When the skew angle ".theta." occurs, appropriate pressurized air flows are generated by the first air pressurization part (17) and the second air pressurization part (18) to compensate for the lifting force.

摘要： In a method of separating neptunium and plutonium, a nitric acid solution containing a mixture of neptunium and plutonium is oxidized by irradiation of ultraviolet light in the presence of a reducing agent. As a result, different valences of neptunium are adjusted all into the valence 5, which can remain in water, and in the meantime, valences of plutonium are adjusted into the valence 4 or 6, which can be extracted in the organic phase. It is therefore possible to separate neptunium and plutonium from each other without difficulty.
