Development of Voxel Based Machining Shape Simulator
Keiichi Shirase,Tomoyuki Kouno,Keiichi Nakamoto (사)한국CDE학회 2010 한국CAD/CAM학회 국제학술발표 논문집 Vol.2010 No.8
In this study, voxel model representation is applied for a geometric machining shape simulator. A voxel model generally requires a huge amount of memory for shape representation, therefore the multilayer Octree structure of voxels is utilized to reduce the memory usage and improve the accuracy for the complicated shape representation of three-dimensional objects. Based on actual tool paths, case studies of machining shape simulation were carried out to examine the relation between the Octree layer levels with calculation time and memory usage. Furthermore, the ability to simulate machining shapes for both 3-axis and 5-axis milling operation were verified.
Direct mapping of potential distribution of Al/poly(alkylthiophene)/Au diode
Keiichi Kaneto,Masahiro Nakagawa,Wataru Takashima 한국물리학회 2004 Current Applied Physics Vol.4 No.2-4
Potential profiles of an Al/poly(3-hexylthiophene), PHT film/Au diode through Al to Au electrodes have been measured directly using a micro-manipulator with a potential probe tip. A steep potential cliff is observed at the interface of Al/PHT for negative biases to Au against Al, indicating the existence of a depletion layer with higher resistance than that of the PHT bulk region. For a positive bias above +1 V to Au, the interface resistance at Al/PHT decreases markedly, resulting in a forward current in the rectification diode. It is found that the contact resistance of PHT/Au is unexpectedly large in spite of the ohmic behavior. The effect of light on the depletion layer is also studied. It is stressed that the contact resistances of PHT and metals are significantly important and determine the performance of organic electronic devices.
