An IGRS system adopts open architecture, that is, the devices abide by the IGRS standard are interoperable with devices following other standards such as Universal Plug and Play (UPnP). The IGRS supports multiple application frameworks and special applications. Developers can use an IGRS media application framework with various media format standards, such as AVS and MPEG-2, to develop multimedia applications. Applied among computers, consumer electronics, and communication devices, the IGRS standard can realize resource sharing and services collaboration in a certain range of wired or wireless network domain.展开更多

In Yantai,Shandong Province, is a joint venture invested by China National Machinery Import and Export Corporation with a registered capital of RMB61.50 million. It mainly produces conical ball bearings, about 90 percent of which are exported to the United States, Korea, Austria,Turkey and Brazil. It is the first enterprise of its kind in China to acquire the certificate of ISO9000 standard. During the past few years, the company,guided by the policy of achieving economic results by management, and taking the world market as its target, has made much headway with growing earnings of foreign exchange from its exports. In 1995, it earned US$813,600 and in 1996, the figure rose to US$5.9336 million. In 1997, from January to August, it earned US$6.032 million,scoring a historical high. So far, its conical ball bearings make up 40 percent of the total exported to the United States from China. To implement the ISO9000 standard and guarantee the high quality of products by way of展开更多
