“Innovation Japan 2013—College Fair” will be held at the above site on the above date.

Innovation Japan is one of the Japan’s largest exhibitions for connecting needs in the industrial field and seeds (research outcomes) of colleges. From our university, a total of 6 research outcomes will be exhibited after passing the rigorous screening, including 1 in information and communication, 1 in materials and recycling, 1 in medicine, 1 in life science, and 2 in devices. Researchers and students who conduct the researches will be presenting at the exhibition. When you visit Innovation Japan, please drop by the Chuo University booth.

[Information and Communication]

Advanced analysis system and computing infrastructure for extremely large-scale graphs on post petascale supercomputers
Katsuki Fujisawa, Professor of Faculty of Science and Engineering

We conduct researches for developing the fundamental technology for next-generation applications on a petascale supercomputer by utilizing the algorithms and big data in the fields of information and mathematical science. Especially, graph data analysis is expected to contribute to social networks, anti-disaster measures, and the elucidation of brain functions, etc. This system is aimed at developing a system for rapidly analyzing super large-scale graphs with new technologies, such as the graph analysis system that has a high parallel performance with respect to large-scale graph data, the mathematical optimization solver using an accelerator, such as GPU, the large-scale graph data storage considering storage hierarchy, and the real-time visualization of super large-scale graphs.

[Materials and Recycling]

Selective recovery of monomers from composite products containing PET or PC with aqueous dilute amine or ammonia solution under hydrothermal conditions
Toshitaka Funazukuri, Professor of Faculty of Science and Engineering

We developed a process for rapidly and highly selectively producing monomers from polymeric materials that include ester or carbonate bonds, such as polyethylene terephthalate (PET) and polycarbonate (PC), by using diluted amine solution as a reaction solvent under the hydrothermal condition. In detail, we measured the speed of monomer production and the rate of monomer collection for pure PET and PC resins, and a variety of actual products that include PET or PC, such as beverage bottles, compact disks, and mobile phone cases by using some diluted amine solutions as reaction solvents, with batch and semibatch reactors, and clarified the variation in reactivity and reaction rate among amines. In any case, there are few solid residues after reaction, the solubility of monomers in water solution is low, and produced monomers accumulate on the bottom of the reactor. Accordingly, monomers can be collected readily. We were able to collect monomers efficiently and highly selectively, verifying the effectiveness of this process.

A system implemented on various types of 3D displays (including glasses-free type) that is utilizable as an optical range finder for visual assistance or as a lateral-viewing endoscope for medical applications
Hisashi Suzuki, Professor of Faculty of Science and Engineering

This is based on the computation technology for reconstructing a 3D space precisely and instantly from the stereo images taken by 3D scopes that can be applied to optical white canes and side-viewing endoscopes. When you want to observe images that look as three-dimensional as possible and in which surface configurations are highly visible, you can conduct processes unique to 3D images, such as image enlargement in the depth direction and re-rendering, regardless of the shooting condition at the time of inputting, which is different from conventional technologies. In addition, as there is a wide array of 3D display devices, including the types of polarization, liquid crystal shutter, parallax barrier, lenticular lens, holographic, and integral photography, this technology can display 3D images in a versatile manner with any types.

[Life Science]

Development of artificial oxygen carrier "HemoAct(TM)"
Teruyuki Komatsu, Professor of Faculty of Science and Engineering

As a new artificial oxygen carrier that can carry oxygen in the living body, we developed “HemoActTM” composed of hemoglobin-albumin clusters in which several molecules of human serum albumin are attached to the molecular surface of hemoglobin. Since oxygen can be absorbed and desorbed stably under physiological conditions, this is expected to be used as an alternate to red blood cells (for transporting oxygen to each tissue) and as an oxygen treatment agent (for supplying oxygen to the location of ischemia). This can be synthesized easily with a high yield (nearly 100%), and any special devices are unnecessary. In addition, it has been verified that its molecular structure is clear, its capacity to carry oxygen is high, oxygen affinity can be adjusted, and blood compatibility is high. In the living body, this is recognized as a plasma protein, and so it is considered that it has no side effects.

Highly efficient and high-beam-quality deep-ultraviolet frequency-conversion lasers realized with the room-temperature-bonding technique
Ichiro Shoji, Professor of Faculty of Science and Engineering

We developed a highly-efficient, high-beam-quality deep ultraviolet laser with a new structure by using the wavelength conversion crystal BBO. In order to compensate for the walk-off effect, which decreases the efficiency of wavelength conversion, we developed a new structure by adding one half-thickness plate to each side, while the thickness of plates is homogeneous in conventional structures, and the efficiency of the new structure is 1.5 times that of conventional ones. We succeeded in embodying a new structure composed of some BBO plates by using the room-temperature-bonding technique, and producing a device with an overall length of 5 mm. For second harmonic generation with a green laser, the deep ultraviolet output of the new device is about 2 times that of the bulk BBO crystal with the same length, and beam quality has been improved. This technology can be applied to other wavelength conversion materials.

Development of peristaltic pomp units using artificial muscle based on motion of intestines
Taro Nakamura, Professor of Faculty of Science and Engineering

The current two main methods for conveying solid-liquid mixed fluid are the earth auger and the gravity conveyance based on water dilution. However, these methods are not preferable, considering the saving of space and resources. Therefore, we developed a new pump with rubber artificial muscle based on the hints from the peristaltic motion of the intestines.

In our research, pump units produced from the rubber artificial muscle were connected, to achieve the conveyance function of the peristaltic motion of the intestines by utilizing the dilation and contraction of each unit, and enable the vertical transportation of solids (powders), liquids, and solid-liquid mixtures with a pressure 1/500 of the conventional value. In addition, this pump can convey materials vertically over a long distance, separate and stir solid-liquid mixtures, and transport materials in the opposite direction, etc.
