Pushing Limits of Leanness in Japanese Architecture: Modern Interpretations of the Frame Structure through Collaboration of Japanese Architects with Structural Engineers

The purpose of this research paper is to clarify the design intentions and methodology behind the experimental application of the Frame Structure by some contemporary Japanese architects through collaboration with structural engineers. The ‘Frame’ is the simplest of structure systems, but was applied to iconic structures such as the Parthenon and Le Corbusier’s Dom-Ino House, each example expressing artistic concepts and technical skills of the concerned era. One of the recent concepts seen in 21st century modern Japanese architecture is the ‘pursuit of transparency and thinness’. This is especially true of SANAA, are presentative group of architects, who – in close collaboration with structural engineers – pursue the quality of extreme thinness in columns and roofs, creatively exploring new methods of using framed structures. This paper focuses on three such projects that exploit the structural aspects of frame construction and, makes an attempt to understand the architects’ intention behind the designs. It presents an analysis of the contemporary interpretation of the traditional frame structure, used by the architects to apparently dissolve the material presence of the building and make it become part of the surroundings. These innovative attempts, made possible through collaboration between architects and structural engineers, signify one of the significant expressions of modernity in Japan

Thermal Studies of Some Minerals, No. 2

For the purpose of discerning the inner structures of chlorite group from one another, thermal variations of the related specimens collected from a chromite deposit in serpentinite have been continuously traced during the heated states at various temperatures up to ca. 950°C kept respectively for long enough hours by means of X-ray diffractometer ac-companying the specific heating apparatus and a few data obtained through infra-red absorption have been added to for reference.今村外治教授退官記念特集

Analysis of spinner straightening utilizing the finite element method

This paper presents analysis methods utilizing the Finite Element Method for spinner straightening, and shows a guideline for optimum conditions. Two types of analysis methods were composed. Model [F-Expl], “full actual model with explicit scheme”, considers the rotational movement of dies as the actual process using the explicit scheme. Model [BndCr], “a model carrying out fundamental analysis on one cross section based on simple bending in the Finite Element Method (FEM)”, uses the FEM only for calculation of simple bending without rotation for obtaining the deformed bar shape. A series of experiments were conducted in an actual production line as well as the analyses by Model [F-Expl] and [BndCr]. The examination mainly focused upon the effect of straightening intensity by changing the die positions. The experimental and analytical results show some mechanism of straightening and a basic guideline for the optimum working condition

Rapid turnover of the CD3ζ chain independent of the TCR-CD3 complex in normal T cells

AbstractThe function of CD3ζ in the assembly and transport of the T cell receptor (TCR)-CD3 complex was analyzed in normal T cells. The ζ chain, but not other chains in the surface TCR complex, rapidly exchanged with newly synthesized ζ. Because ζ was expressed independently from the complex, the TCR complex may be transported to the surface along the ζ turnover pathway by association with ζ. These data suggest the dynamic nature of ζ metabolism and provide the evidence that a single component in a multisubunit receptor exhibits independent metabolism from the rest of the complex
