平坦化ＣＭＰにおけるパッドドレッシングに関する研究(第2報)

The novel conditioner was developed for uniform conditioning across a pad. The conditioner is composed by bendable fibers. Therefore, each abrasive conforms independently to the pad surface, differently from the traditional conditioner of plate type. The removal rate using the developed conditioner is equal to that using the traditional conditioner. However, the cut rate of pad using the developed one is tenth part of the cut rate using traditional one. Therefore, it was demonstrated that the developed conditioner realized more efficient conditioning. In addition, in order to evaluate the conditioning non-uniformity effectively, novel uniformity evaluation method was developed. The principle uses color variation by abrading the pad dyed on the surface. As the result, the conditioning non-uniformity was 8.3% with the developed conditioner, compared with 23.8% with the traditional conditioner.textapplication/pdfdepartmental bulletin pape

Search for matter-dependent atmospheric neutrino oscillations in Super-Kamiokande

We consider ν_μ→ν_τ oscillations in the context of the mass varying neutrino (MaVaN) model, where the neutrino mass can vary depending on the electron density along the flight path of the neutrino. Our analysis assumes a mechanism with dependence only upon the electron density, hence ordinary matter density, of the medium through which the neutrino travels. Fully-contained, partially-contained and upward-going muon atmospheric neutrino data from the Super-Kamiokande detector, taken from the entire SK-I period of 1489 live days, are compared to MaVaN model predictions.We find that, for the case of 2-flavor oscillations, and for the specific models tested, oscillation independent of electron density is favored over density dependence. Assuming maximal mixing, the best-fit case and the densityindependent case do not differ significantly.journal articl

Investigative Report Writing Support System for Effective Knowledge Construction from the Web

Investigative reports plagiarized from the web should be eliminated because such reports result in ineffective knowledge construction. In this study, we developed an investigative report writing support system for effective knowledge construction from the web. The proposed system attempts to prevent plagiarism by restricting copying and pasting information from web pages. With this system, students can verify information through web browsing, externalize their constructed knowledge as notes for report materials, write reports using these notes, and remove inadequacies in the report by reflection. A comparative experiment showed that the proposed system can potentially prevent web page plagiarism and make knowledge construction from the web more effective compared to a conventional report writing environment.journal articl
