Publikováno v: Experimental Gerontology. 26:397-406
A simple and reliable method for the separation of endothelial cells from the thoracic aorta of rats was established in the present study. The cultured endothelial cells separated by this improved explantation method showed typical characteristics of

Design of power amplifiers using high breakdown GaN HEMT devices
Autor: N. Ui, J. Shumaker, M. Ohoka
Publikováno v: 2008 IEEE International Conference on Microwaves, Communications, Antennas and Electronic Systems.
Some applications of the new GaN HEMT technology have been demonstrated. Class AB allows either very wide bandwidth or very high power. Doherty produces very good efficiency that is correctable for acceptable linearity at high efficiency.

Rapid Fabrication Process for High Aspect-Ratio Embedded Microchannels with Orifices Usinga Single SU-8 Layer Onamask
Autor: Isaku Kanno, H. Yamamoto, Hidetoshi Kotera, Masao Washizu, M. Ohoka, Takaaki Suzuki, T. Tokuda
Publikováno v: 19th IEEE International Conference on Micro Electro Mechanical Systems.
In this paper, a novel single-mask fabrication method for high aspect-ratio embedded microchannels and high-density arrayed micro-orifices is presented. The proposed process is based on inclined UV lithography to expose a single layered photoresist c

Publikováno v: IEEE MTT-S International Microwave Symposium Digest.
A novel offset self-aligned process has been used to fabricate an internally matched power FET with a 2-*3000- mu m gate width which at 14 GHz has produced 34.4-dBm output power, 6-dB gain, and 32% power-added efficiency at the -1 dB gain compression

Tensile test using hollow cylindrical specimen
Autor: Y. Takahashi, M. Ohoka, A. Funato
Publikováno v: International Journal of Rock Mechanics and Mining Sciences. 34:88.e1-88.e11
Tensile test using hollow cylindrical specimen is suitable for evaluating mechanical properties of soft rock under controlled conditions of the pore water. The authors tried to adopt this test for the Tertiary tuff, and got satisfactory results as fo
