ジャーナル フリーIn this review paper, the system of International Standards as well as Japanese Industrial Standards and their relation are summarized to introduce how these standards and specifications are established under International Standards Organization or Japanese Industrial Standards Committee. The present situations and movements of the vacuum related standards are also briefly explained for those who are using or planning to use them.

ジャーナル フリーStandards of calibration for vacuum gauges by direct comparison with reference gauge were described. Japanese standard, JIS Z 8750 (Methods of calibration for vacuum gauges), was established in 1962. International standard, ISO/TS 3567 (Vacuum gauges—Calibration by direct comparison with a reference gauge) was established in 2005.

ジャーナル フリーDomestic standard of the leak testing is enacted as Japan Industrial Standards. The conformity is advanced between these domestic standards and ISO (International Organization for Standardization) standard. ISO 9712 (Non-destructive testing.—Qualification and certification of personnel) was revised to include the leak testing of qualification and certification in 2005. It will be executed in the near future though it is thought that it takes time to an international conformity with JIS Z 2305 of a domestic standard. On the other hand, the calibrated leak will be offered by domestic organization.

ジャーナル フリーTo keep flexibility on construction of vacuum system, understanding of standardization scheme for demountable sealing system consisting of flanges and metal gasket or elastomer O-ring is highly beneficial for both suppliers and users of vacuum equipments. Here we present main contents of international and national standards of flange sealing systems and their correlation, along with some commentaries on states of conformity with standards of commercially available vacuum flanges. Outlines of standards of vacuum fittings, and recent activities for revision and establishment of standards are also reported.

ジャーナル フリーThe crystallinity of polycrystalline Si (poly-Si) film produced by the combined method of solid phase crystallization (SPC) followed by excimer laser annealing (ELA) or ELA followed by SPC is examined by observing the internal stress and the crystal defect. Tensile stress relaxation occurred when SPC was performed before or after ELA. The defect densities of poly-Si films recrystallized by ELA, ELA followed by SPC, and SPC followed by ELA decrease in this order.

ジャーナル フリーWe measured mass and kinetic-energy distribution of desorbed ions using a miniature cylindrical mirror analyzer (CMA) and synchrotron radiation under the single-bunch mode operation. We have applied it for the measurements of kinetic energy distribution of ions desorbed by N 1s transitions of condensed NH3.

ジャーナル フリーThe development of the high-efficiency a-Si:H solar cells has been achieved, fabricating the light trapping structures by the use of Al2O3 fine particles. As a result of the inserting the Al2O3 fine particles between the a-Si:H and the Ag back electrodes, the remarkable increase in the short circuit photocurrent density Jsc was achieved while no significant change was observed both in the open circuit voltage Voc and the fill factor. Observation of quantum efficiency spectra for the solar cells with Al2O3 particles indicates that this increase in the photocurrent density is due to the improvement of the sensitivity in the long wavelength regime (570-750 nm). It is concluded that Al2O3 particles cause random reflection of incident light at the interface, leading to an increase in the optical path.
