摘要:
An operation arrangement work is accelerated by improving efficiency of not only process of generating an operation arrangement proposal but also process of confirming whether the operation arrangement proposal is good or not by a user. An operation support system has an operation arrangement proposal generation part (1110) which executes automatic generation of an operation arrangement proposal, a diagram prediction part which executes simulation of train operation in the future, a diagram display part (1120) which displays an operation schedule and the operation arrangement proposal as a diagram, and a user input part which receives input of a parameter from the user. The system has a snapshot restoration part (1130) which restores snapshots of the operation arrangement proposal in an automatic generation process on the basis of a diagram change history outputted by the operation arrangement proposal generation part (1110), and a snapshot display input part (1140) which displays to the user a snapshot according to input from the user.

The invention starts from a known component of quartz glass for use in semiconductor manufacture, which component at least in a near-surface region shows a co-doping of a first dopant and of a second oxidic dopant, said second dopant containing one or more rare-earth metals in a concentration of 0.1-3% by wt. each (based on the total mass of SiO2 and dopant). Starting from this, to provide a quartz glass component for use in semiconductor manufacture in an environment with etching action, which component is distinguished by both high purity and high resistance to dry etching and avoids known drawbacks caused by co-doping with aluminum oxide, it is suggested according to the invention that the first dopant should be nitrogen and that the mean content of metastable hydroxyl groups of the quartz glass is less than 30 wtppm.

A mixed quartz powder contains quartz powder and two or more types of doping element in an amount of from 0.1 to 20 mass %. The aforementioned doped elements include a first dope element selected from the group consisting of N, C and F, and a second dope element selected from the group consisting of Mg, Ca, Sr, Ba, Sc, Y, Ti, Zr, Hf, the lanthanides and the actinides. The “quartz powder” is a powder of crystalline quartz or it is a powder of glassy SiO2 particles. It is made form natural occurring quartz or it is fabricated synthetically. The “quartz powder” may be doped. The compounding ratio of the total amount (M1) of the aforementioned first elements and the total amount (M2) of the aforementioned second elements as the ratio of the number of atoms (M1)/(M2) is preferably from 0.1 to 20. Al as well as the aforementioned doped elements is preferably included in a mixed quartz powder of this invention.

A computer-readable, non-transitory medium stores a program that manages compressed file groups on a plurality of slave servers. The file groups include compressed files that are to be searched and have character strings. Each of the compressed file groups is expanded, using a Huffman tree that was used for compressing the compressed file group. A common compression parameter is generated based on appearance frequency, by summing, for each character, the appearance frequency in each of the compressed file groups. The expanded files are recompressed using the common Huffman tree such that sums of the access frequencies of the compressed files that are origins of the recompressed files are substantially equivalent among various slave servers. New archives including the re-compressed files are transmitted to the respective slave servers.
