- PET and SPECT have very high sensitivity to detect molecule by means of radiation detection, and are considered to be excellent tools for molecular imaging. We are studying and developing data analysis techniques for PET and SPECT data. Using our approaches, we can analyze data in quantitative manner, and obtain physiological functions in living organism.
- 実用化イメージ
-
Pharmaceutical companies who are interested in using PET to evaluate efficacy of new drug. Companies which are related to medical informatics, medical equipments.

- The Smart Aging International Research Center (SAIRC) was founded on 1 October 2009. This Center proposes the creation of a new field to produce well-rounded personnel who have gained “totally comprehensive intelligence” from their experience, in order to cope with various problems associated with the diverse and complex super-aging society. To this end, the Center will promote interdisciplinary cooperative research, international collaborative research projects, and research collaborations with industry, as well as disseminate and exchange information by holding international conferences and symposia. The SAIRC is designed to develop an approach for maintaining and improving brain and mental health in a diverse and complex society from the standpoints of brain science, with the aim of maintaining and improving brain functions; cognitive neuroscience and psychology, with the aim of maintaining a healthy and tranquil state of mind at each aging stage; and philosophy, phenomenology and ethics that provide a radical reconsideration of the concept of the “mind.” We welcome collaborative researches with companies, and academic consultations.

- We study and develop mobile robotics technology for lunar and planetary exploration. Our technology is featured by rich experience in locomotion mechanisms for highly rough terrain and advanced slippage control in loose soil environment. Also by 3D map building technology using a laser scanner for autonomous collision avoidance and for operator assistance in remote control/tele-operation. We also contributed to the design and development of Hayabusa and Hayabusa-2, which are sample-return probes developed and operated by Japanese space agency JAXA.

- Tadokoro Laboratory developed ‘Active Scope Camera,' a world-unique rescue robot that can search deep in rubble piles of collapsed structures through a gap of a few cm wide. It also developed ‘Quince,' a world-unique unmanned ground vehicle that could survey the second to fifth floors of Nuclear Reactor Buildings of Fukushima-Daiichi Nuclear Power Plant. Its technologies was applied industries, including unmanned transfer vehicle for outdoors under ice and snow environment being actually used in a factory of Toyota Motor East Japan, and ‘Robo-Scope' for debris inspection in collaboration with Shimizu Corporation.

- The new kind of volcanoes, petit-spot, are located off NE Japan and Chile. They erupt at a submarine portion to be far from tectonic plate boundaries (e.g., mid-oceanic ridges and volcanic arcs) of the usual sites of volcanoes, earthquakes, and related geologic activity. The magmas have extremely high carbon dioxide and possibly originate from the base of tectonic plate.
- 実用化イメージ
-
The magma is squeezed upward and erupts in deep submarine environment wherever the tectonic plate flexes and fractures in the world. Collaborating work with business community would be required in order to search the submarine volcanoes and their related mines.

- Atomic diffusion bonding of two flat wafers with thin metal films is a promising process to achieve wafer bonding at room temperature. High surface energies of metal films and a large atomic diffusion coefficient at the grain boundaries and film surfaces enable bonding at room temperature without unusually high loading pressure. This technique, which enables bonding of any mirror-polished wafer, is gaining wider use for fabricating optical and electrical devices. Moreover, bonding of mirror polished metals and polymer sheets can be achieved, which further extends the application of this bonding technique.
- 実用化イメージ
-
Optical, power and electrical devices, MEMS, bonding of polymer sheets, metals, and ceramics for precision mechanical equipments.
