Breaking symmetry in glass by femtosecond laser irradiation (2006)
Kazansky, Peter G., Yang, Weijia, Brichi, Erica, Kitagawa, Ryota, Takebe, Hiromichi
It is observed that writing by femtosecond laser from left to right can be different from writing in the opposite direction. Structures with broken mirror symmetry in chalcogenide glass are...
Materials and Manufacturing Processes. Volume 9. Number 4. 1994 (2006)
Lu, G. Q., Hoyer, Jesse L., Ahn, Jung-Ho, Muller, H. R., Iwaida, Shinji, Lograsso, B. K., ...
A new model for monosized particle packing is developed in this study in simulating CIP powder compaction. The model uses a central growth method by which particles are placed from a central particle...

The tetragonal to monoclinic transformation in Y-TZP specimens and mullite/Y-TZP composites containing 5 vol% mullite was investigated by scanning acoustic microscope (SAM). The transformation...
Oxidation of Sintered Aluminum Nitride by Oxygen and Water Vapor. (1998)
Kuromitsu, Yoshirou, Yoshida, Hideaki, Ohno, Shinji, Masuda, Hirohisa, Takebe, Hiromichi
Oxidation behavior of sintered AlN by oxygen and water vapor was studied for the purpose of surface water treatment at 1400 C. The partial pressure of oxygen, P(O2) was controlled at 10 to the -10...
Fabrication of Alumina Sheets by Extrusion. (1998)
Takebe, Hiromichi, Yoshida, Masatomo, Hayashi, Koichi, Morinaga, Kenji
By adding methylcellulose and glycerol to a sys TEM of water, ammonium polyacrylic acid, and alumina powder, alumina suspensions for extrusion were prepared. The effect of the additives on the...

A powder processing technique is developed for the fabrication of tetragonal zirconia nickel functionally gradient materials. The powder volume fraction, the linear shrinkage during drying, and the...
Slip Casting of Continuous Functionally Gradient Material. (1998)
Chu, Judy, Ishibashi, Hirotaka, Hayashi, Koichi, Takebe, Hiromichi, Morinaga, Kenji
The basic principle behind this study is the utilization of the density difference among the species used and the size difference among the particles within the powders used to influence the...
Development of Pressureless-Sintered h-BN Composites in Horizontal Continuous Caster. (1998)
Kurita, Sumihiko, Nakashima, Masazumi, Takebe, Hiromichi, Morinaga, Kenji
Using turbostratic-BN, AlN, SiO2 powders as starting materials, various types of h-BN composite materials were fabricated by pressureless-sintering. Thermal expansion coefficient, flexural strength,...
