- Toward realizing a high-performance neuromorphic vision processing system, our research involves a neural network model of spatial perception based on motion-stereo vision and its implementation on a very large scale integrated circuit (VLSI). Important parameters for spatial perception such as time-to-contact, orientation, and the shortest distance to plane surfaces of a target object are recognized by using the model without knowing moving direction and velocity of the object. We have developed a VLSI capable of performing visual perception based on the model with low power consumption, reduced less than 1/100 compared with a commercial CPU.

- Research Center for Neutrino Science established ultra-low radioactivity environment (trillion times lower than natural environment) with 1200 cubic-meter organic scintillator detector at 1000m underground where very stable temperature/humidity and low vibration are maintained. We are pursuing high sensitivity measurements, especially neutrino observation, and are also developing purification system for ultra-low radioactivity and high performance radioactivity detectors.
- 実用化イメージ
-
The established ultra-low radioactivity environment is suitable for rare phenomena study and is also applicable for high sensitivity radio-impurity measurement. It may also apply to investigation of biological influence of low radioactivity irradiation. The other applications such as neutrino detection technique for monitoring nuclear reactors and medical use of high sensitivity radioactivity detectors may also be considered.

- In spite of the long history of digital dentistry, the accuracy of the prosthetics fabricated with CAD/CAM systems is far from satisfactory. Jaw opening during taking impression elicits deformation of the mandible and the lower dental arch, and consequently causes the inaccuracy of occlusal relationship of the upper and lower dental arches on the CAD data. The method presented here utilizes the check-bite record at the maximum intercuspation to correct the relative positions among the teeth in the dental arches as well as between the arches. After this correction, the accuracy of the CAD data is satisfactory enough for the fabrication of the dental prosthetics which need no adjustment during their setting.
- 実用化イメージ
-
This method uses the newly-developed check-bite recording technique together with the conventional precious impression or optical impression techniques. It can easily be applied to the commercial CAD/CAM systems in the market. We hope to collaborate to the manufacturers of dental CAD/CAM systems to increase the accuracy of the systems.

- Global intra-chip interconnection complexity not only limits the clock frequency, but causes clock-skew problems in synchronous system. Asynchronous control-based circuit design, where timing is managed locally, is one of the possible approaches to solve the above serious interconnection problem because the asynchronous design has many features which are low power dissipation, high speed and robustness. However, communication-steps overhead caused by handshaking much would generally affect the cycle time.
- In our approach, a high-speed asynchronous data-transfer scheme is proposed based on multiple-valued encoding and current-mode circuits. The multiple-valued encoding enables to improve communication protocol essentially. Moreover, the current-mode circuits which has high-driving capability makes it possible to perform high-speed intra- and inter-chip network. By using this method, we expect that we can conduct effective collaborative research in high-speed and low-power communication LSIs such as a many-core LSI and a multi-module NoC.

- We successfully realized millisecond-order X-ray phase tomography using a fringe-scanning method in grating-based X-ray interferometry. We obtained phase tomograms with a measurement time of 4.43 ms using a white synchrotron X-ray beam. The use of a fringe-scanning method enables us to achieve not only a higher spatial resolution but also a higher signal-to-noise ratio than that attained by the Fourier transform method. In addition, our approach can be applied to realize four-dimensional or high-throughput X-ray tomography for samples that can be rotated at a high speed.

- Breast cancer is one of the most common malignancies in women worldwide. Therefore, it is very important to investigate biological features of breast carcinoma in order to improve clinical outcome of the patients. It is well known that estrogens play important roles in the development of human breast carcinomas, and endocrine therapies are frequently used in these patients to block the intratumoral estrogen actions. In the Division of Pathology and Histotechnology, we analyze hormone actions in breast carcinoma by pathological methods as well as various molecular biological techniques.
