日本手机设计纵览 2007-06-10 04:35:40 The main makers of cell phones in the world are Nokia, Motorola and Samsung. However, the situation in Japan is quite different from other cultures or countries. Most cell phones used in Japan are made by domestic companies such as Sharp and NEC. Since the companies have been making their cell phones only for Japan, they have been uniquely developed in functions and designs beyond what is seen in the United States.Sharp kept the top market share among japan's handset venderos according to IDC Japan. Sharp was followed by Panasonic at 11.4% , NEC 10.4% , Sony Ericsson 9.2% , Toshiba 9.1% and other vendors splitting the remaining 38.7% of the market. Overall handset shipments increased 11.2 % from the same period in 2005, reaching 12.95 million the last quarter of 2006 "Sharp holds top handset market share as of the last quoarter of 2006" - IDC Japan Media Skin by Tokujin YoshiokaJapanese people like multifunctional or hybrid cell phones.

Reference Book 14: Handbook of Plastics Joining 2007-06-13 22:01:51 Introduction简介:Handbook
of PlasticsJoining
is a hands-on guide to choosing and using old and new technologies for joining plastics and elastomers. Includes detailed discussions of over 25 techniques used to join plastics to themselves and to other materials. Advantages and disadvantages of each technique along with detailed discussions of applications are presented. A second section is organized by material and provides details of using different processes with over 50 generic families of plastics and how different techniques and operating parameters affect weld strength and other criteria. Handbook of Plastics Joining is an excellent reference and an invaluable resource for novice and expert alike in determining the best joining technique for their application and providing guidance in how to design and prepare for production. Summary: This practical guide to plastic joining processes is composed of two parts: processes and materials. The processing part is divided into 15 chapte
