Combined Antenna Covering Cellular, GPS, and Wireless LAN Systems for Notebook PCs HOTTA Hiroyuki/ TESHIMA Masao/ MIZOGUCHI Satoshi With the wide dissemination of notebook PCs in recent years, wireless communication systems such as wireless LAN and Bluetooth® have come into widespread use for notebook PCs in various situations. There is growing demand for notebook PCs that can provide a comfortable wireless communication environment anywhere and anytime. However, as the number of wireless systems is increasing, it is becoming difficult to equip notebook PCs with numerous antennas in a limited space. To solve this problem, Toshiba has developed a combined antenna that can cover the frequency bands of cellular, Global Positioning System (GPS), and wireless LAN systems and mounted it on notebook PC products. This antenna, based on a trapezoid monopole antenna with wideband characteristics that we have developed, has been modified to give it multiband capability. The combined antenna covers the frequency range from 1.5 GHz to 2.2 GHz, and its impedances maintain the proper characteristics for the respective systems. Improvement of Rigidity and Impedance-Matching Technology of Printed Wiring Board in Notebook PCs HARAGUCHI Teruhisa/ NAKAJIMA Yuji/ KOGA Yuichi Users of mobile notebook PCs have many requirements including a thin profile, light weight, long battery life, high quality, shock durability, high security, and network connectivity at all times. To meet these requirements, Toshiba released the dynabookTM SS RX1 in June 2007. We have newly developed the dynabookTM SS RX2, whose durability has been improved while maintaining the features of the RX1 such as a thin body, light weight, and long battery life. The rigidity of the printed wiring board (PWB), which is one of the basic components of a notebook PC, is about 40% greater in the RX2 than in the RX1. Moreover, the amount of PWB bowing at high temperature in the RX2 is about 50% lower than in the RX1. Impedance matching is also achieved by optimizing the specifications to maintain the functionality. Metrology and Inspection Technologies for 32 nm-Generation Semiconductor Wafers YAMAZAKI Yuichiro As the mass production of 32 nm-generation semiconductors will begin in the near future, metrology and inspection technologies have become even more critical to improve the production yield compared with previous generations, and solutions to the technical problems are becoming clear. To improve the production yield, not only the control of random defects but also the inspection and control of systematic defects have become increasingly important. With the aim of realizing a systematic defect control system including both a defect inspection system and a post filtering system, Toshiba has been developing novel defect filtering technologies for systematic defects and a detection and control system for lithography-induced hot spots. New Compact, Lightweight, and Resource-Saving SCiBTM Rechargeable Battery Pack for HEV Application KOSUGI Shinichiro/ TAKAMI Norio/ HONDA Keizoh Toshiba has developed the SCiBTM battery for hybrid electric vehicle (HEV) application featuring high intrinsic safety with a slower reaction rate in the event of an internal short circuit. Furthermore, the SCiBTM exhibits a steep voltage gradient in the initial stage of the over-discharge or overcharge regions, allowing easy detection of unsafe states. It also has larger available energy with high input and output power capabilities over a wide state-of-charge (SOC) range. Based on these features of the SCiBTM, we have developed and confirmed the effectiveness of a new SCiBTM battery pack for HEV application providing superior available energy density with high power capabilities, and incorporating protection circuit boards with a newly developed application-specific integrated circuit (ASIC). FA3100S Model 9500 Industrial Computer Equipped with Dual-Core Processor MIMURA Akihiro/ GOTO Tatsuya Customers' needs in the field of industrial computers have become diversified with the recent progress of personal computer technology, including not only high performance using high-end central processing units but also configurations in accordance with the purpose of use and installation site. In response to these circumstances, Toshiba has developed and commercialized a new industrial computer, the FA3100S model 9500, equipped with a dual-core processor, the Intel® CoreTM2 Duo processor. This model is the flagship product of our desktop-type industrial computers, offering both high-speed processing performance and high scalability, in addition to the reliability and environmental resistance of our conventional products. Digital Terrestrial Television Broadcasting System in Brazil SAWADA Takeshi/ KANEKO Tomoaki/ YAJIMA Takenori Digital terrestrial television broadcasting (DTTB) was launched in Brazil in December 2007. The technology used is based on the Japanese DTTB standard with some modifications. Toshiba has participated in promoting the Japanese standard in Brazil since the beginning of this project, and developed the encoder/multiplexer (ENC/MUX) system and studio-to-transmitter link/transmitter-to-transmitter link (STL/TTL) equipment and transmitter system as a package for the stations in major cities of Brazil. In this project, it has been necessary to overcome differences in the specifications of and customers' requirements for the DTTB system in Brazil compared with those in the Japanese system. The first broadcasting system for Sao Paulo was delivered in a short time with a cooperation of local receiver manufacturers. |
