PCD is expected to apply to a wear part or a sliding part because PCD has superior mechanical properties. Therefore, high efficiency and high quality method of processing PCD is required. The authors proposed the high-speed constant-pressure grinding that is processing method to increase the grinding wheel speed with…
This report contains the development and construction of a new patented doctor blade. A doctor blade is used when creping soft paper from a large rotating Yankee cylinder. At the current state the ...
Rubbing noise of a paper with guides in paper-handling mechanism is getting louder now with the higher sheet feeding speed in printer or copy machine. This research deals with the paper vibration caused by sliding contact with guides. The purpose of this research is establishing a theory of rubbing noise. First, it wa…
We investigate effects of solute atoms on twin boundaries and surfaces of Mg alloys by First-principles calculations. Most of solute atoms are stable or unstable at each twin boundary sites, depending on the atomic radius; solute atoms larger than Mg are stable at the extension site on twin boundaries and unstable at…
Experimental evaluations of interlaminar tensile strength for stitched CFRP curved panels were carried out. Vectran^[○!R] fiber with 200 denier was used as stitch thread. L-shape specimens were loaded by four point bending test, and interlaminar tensile strength was measured. Interlaminar tensile strength of stitched…

Polymer coatings have been widely applied as surface treatments for various metallic materials. The role of polymer coatings has generally been to provide a barrier against corrosion species in order to protect the surface of metallic materials from corrosive attack. One of the most important characteristics required…
We have developed a coronary artery bypass graft connecting device. This device can achieve bypass formation easily with the integrated low energy adhesion technique which can adhere living tissues with minimal invasion by using low level heat and pressure energies. Branch vessels from the aorta (inner diameter < 4 mm…
The authors are developing a manufacturing process of a metal nano dot array on a plastic substrate. In this paper, machining technology of a quartz glass substrate with fine groove array used for the process is studied. It is shown that a fine groove narrower than 300 run can be machined on a quartz glass plate by us…
The biopolymer cellulose is an inexhaustible source for the synthesis of various functional materials for energy storage. It should be accounted as an alternative to the currently most used precursors (coal tar pitch and synthetic polymers) of carbon nanostructures. In this work, cellulose-based carbon nanofibers (CNF…
The article describes one of possible ways of combat vehicles robotization and realization due to the extensive modernization of outdated models of military mobile equipment. The analysis of probable options of possible usage of similar equipment is carried out, the basic vehicle for extensive modernization for the pu…
Nowadays, PEFC-CGS is getting attention as a distributed energy system. It has high efficiency, and a lot of studies of PEFC-CGS were reported. But almost of them didn't consider energy prediction error. In this study, in order to evaluate energy-saving performance of PEFC-CGS for residential use with energy predictio…

As development of micro electro mechanical systems (MEMS) technology, microforming is gaining attention. And, lubricant-free microforming process is a strong demand. Due to the low effect of lubricant in microscale dimensions, the tribological issues in microforming confronts with further severe problems to enhance th…
In order to precisely investigate molten core relocation behavior in the Fukushima Daiichi nuclear power station, we have developed the detailed and phenomenological numerical simulation code named JUPITER for predicting the molten core behavior including solidification and relocation based on the three-dimensional mu…
Graphene grown on a substrate is likely to be polycrystalline. Defects consisting of pentagons or heptagons of C atoms make rows at grain boundaries in such polycrystalline graphene. In this paper, the tensile strength of polycrystalline graphene is investigated using the method of atomistic simulation. Simulation mod…
In this talk, I introduce the interdisciplinary research field "Molecular Robotics", which is being formed in between chemistry and robotics. I explain the notion of molecular robots and then introduce the five-year research project "Molecular Robotics", which began in 2012 as an innovative area funded by MEXT, Japan.…
The air fleet in Russia was being created on the base of foreign aircraft technical equipment. After The October Revolution it was decided to graduate high-skilled air force personnel with engineering education. They were to design domestic airplanes and aircraft engines, to organize their production, to be ready for…
Deformation behaviors in Bimodal microstructure were studied by a crystal plasticity software code. The Bimodal microstructure consists of fine and coarse crystal grains. Some numerical models for such structure were constructed by the Voronoi dynamics software where growth process of crystal nuclei were simulated. Re…
