摘要:
In a computer system which includes storage units of a hierarchy structure, a method of relocating a file stored in a source storage unit includes the steps of determining an access indicator indicative of the efficiency of access to the file in response to a relocation instruction, determining a relocating destination storage unit of the file in the storage hierarchy, and relocating the file in the determined destination storage unit.

A method of controlling execution of a series of jobs includes the steps of executing the series of jobs sequentially, determining jobs to be rerun in the series of jobs as rerun jobs in accordance with the file access information when one of the series of jobs is terminated abnormally, the file access information indicating access to each of the files by each of the jobs, and rerunning the rerun jobs. When the rerun jobs are determined, the necessity of access to each of the files by each of the rerun jobs is determined in accordance with the file access information, and access to the files by each of said rerun jobs is selectively skipped in accordance with the result of determining the necessity of the access. Furthermore, when the series of jobs are executed, the files are allocated to an allocatable storage device in accordance with the file access information so that the jobs to be rerun become minimal.
摘要:
The resonator comprises two capacitively coupled electrodes. One of the electrodes is made of a p-type doped semiconductor material, whereas the other electrode is made of an n-type doped semiconductor material. The invention also comprises a method of using this specific selection of the doping for enhancing the output signal current from a resonator.

A high-frequency module is provided that includes a reception portion that processes a reception signal received by a reception antenna, and a transmission portion that processes a transmission signal to be supplied to a transmission antenna. The reception portion includes a demultiplexer circuit that divides a reception signal received at the reception antenna to two reception lines having different frequency bands from each other. The transmission portion includes power amplifier circuits and a demultiplexer circuit. The high-frequency module is configured so that the demultiplexer circuit and the like included in the reception portion, as well as the power amplifier circuits and the demultiplexer circuit included in the transmission portion, are provided inside a multi-layer substrate.

The invention provides a high-speed tool steel gear cutting tool in which fracture or chipping does not occur at the cutting edge, and which realizes excellent cutting performance over long periods. Moreover, a method of manufacturing a gear cutting tool including: a step for quenching a tool material comprising high-speed tool steel and which has been rough processed to a shape corresponding to a final shape of a gear cutting tool, to transform a structure of the tool material into martensite, a step for temperling the tool material after quenching to transform any residual austenite dispersingly distributed throughout a matrix of the martensite structure formed by the quenching, into martensite, and a step for finishing the tool material after tempering to a final shape, is characterized in that the tool material after quenching is subjected to sub-zero treatment involving cooling and holding at a temperature of less than −150° C.
摘要:
A heat treatment method of steel is capable of enhancing wear resistance, mechanical properties and dimensional stability of the steel due to the reduction of the retained austenite amount to substantially zero. In the method, an article of the steel is subjected to a quenching and then subzero treatment including cooling it at a cooling rate of 1 to 10° C./min. to a cooling temperature and holding the cooling temperature for a predetermined period of time.
摘要:
A flexible tube having high flexibility and high resistance to pressure and causing little twist and elongation when subjected to a high internal pressure. A flexible tube 21 has an inner tubular layer 11 made of a soft resin, an inner spiral reinforcement 1 made of a hard resin and helically wound around the inner tubular layer 11, an intermediate tubular layer 12 made of a soft resin and surrounding the inner spiral reinforcement 1, and an outer spiral reinforcement 4 made of a hard resin and helically wound around the intermediate tubular layer 12 in the direction opposite to the winding direction of the inner spiral reinforcement 1. As the direction of the helix of the inner and outer spiral reinforcements 1 and 4 are opposite to each other, forces due to internal pressure acting to twist the helixes are canceled out.
