Development of Low-Melting Glass to be used as Low Temperature Sealant
Hitachi and Hitachi Chemical have jointly developed a 220-300 degrees Celsius, low-melting temperature glass (“low-melting glass”). The glass has been developed as a low temperature sealant which does not contain regulated materials such as lead or halogens such as fluorine or iodine. The new product is relatively inexpensive in comparison to gold-tin solder, a conventional low-temperature sealant, while providing better sealant properties than adhesive resins against air and moisture.

Development of WAN Accelerator Equipment by Hitachi Offering 15 time Faster Data Transfer Speed over Conventional TCP/IP
There is growing demand for transferring large volumes of graphical data such as CAD (Computer-Aided Design) data between global Wide Area Networks (WANs). However, the currently used TCP/IP protocol does not offer an adequate performance over long-distance global links due to severely impacted throughput by round trip delay and packet loss. Commonly used content-cache technologies won’t be able to remedy this issue due to their waste of bandwidth when delivering large volumes of frequently updated data. Read more
Development of Compact Magnet with magnetic Flux Density of 3.1 Tesla
Hitachi has announced the development of prototype of a super compact magnet which fits into an individual palm but offers a powerful magnetic flux density of 3.1 tesla. The new magnet is made of a small refrigeration part which is attached to cylindrical vacuum chamber containing a high temperature superconductor made of gadolinium-barium-copper-oxide substance which has zero resistance when it is cooled to -183 degrees Celsius. The magnet comes in a form factor of 23.15 x 11.5 x 6 cm, weighing only 1.8 kg. Read more

Development of New technology for Extending the Life of Industrial Lithium-ion Batteries by HITACHI
Like any other new novel technology with a proven concept and then its commercialization, the cost of the development at first is never an issue until it goes through the mass market. Material science by no means is an exception to this theory, where the scientist usually work with a material which speeds up the making of the final product regardless of its cost and its scarcity, and later on move to an alternative substance which provide a cost effective product with same set of features if not better. Lithium-ion battery technology some how follows the same processing path. Today, lithium-ion batteries are in use in a wide array of consumer electronic applications such as mobile phones, Laptop PCs to name a few, as well as hybrid automobiles and other vehicle applications, where in a not so distance future are expected to be used as compact storage devices in connection with wind power generation and other power facilities designed exclusively to contribute in reducing environmental impact. Currently, the main cathode material used in these batteries are cobalt, at least for the consumer applications, which forms the largest market segment for these type of batteries. However, their growing popularity raised a concern in securing a steady supply of cobalt, being a scarce resource. Based on this, Hitachi has turned its attention to an alternative material in replacing cobalt in this type of application. Read more
Construction of World’s Tallest Elevator Research Tower by HITACHI
Hitachi made an announcement that it will complete the construction of “G1TOWER”, a research elevator tower that is currently under construction at an elevator R&D and manufacturing base in Hitachinaka, Ibaraki Prefecture. The new tower measuring 213 meters will be the tallest elevator research facility in the world. The tower is designed to be used for verification tests on the world’s fastest elevator, with a speed of 1,080m/min, as well as product development targeting the world’s largest, high speed, high capacity elevator capable of carrying a five tone load with a speed of 600 m/min. Furthermore, the new tower will be used for development of vibration suppression control devices as well as internal air pressure adjustment devices to improve riding comfort during high-speed operations.

Development of Industry’s first 7200 RPM 2TB Enterprise level hard drives by HITACHI
With growing needs for such application as data warehousing, disk-to-disk backup, cloud computing as well as huge scale-out storage implementation has contributed in importance of some critical attributes such as storage density, GB-per-watt and cost-per-GB. At the same time enterprises are faced with the growing volume of digital content, maximum storage rack-density and floor tile space and they need to reduce the overall energy consumption, forcing the data centers to push the boundaries to make storage more efficient through implementation of such technology as virtualization, thin provisioning and de-duplication. To respond to these needs, Hitachi Global Storage Technologies made an announcement on development of and shipping of industry’s first enterprise class 7200 RPM 2TB Hard Drives. The new Ultrastar A7K2000 has been designed, manufactured and tested in ensuring enterprise-class mean-time-between-failure (MTBF) of 1.2 million hours for demanding 24×7 nearline applications making it an ideal solution for such application as data warehousing, disk-to-disk backup, cloud computing and massive scale-out storage implementations.
