A Section and B Section are the neared vane, which rotate together with rotor clockwise. The turning Vane A increases the cubage of low pressure transitional area, oil being sucked into pump. Fuel between vane A and Vane B is brought to high pressure transitional area as the vane go around clockwise. In high pressure transitional area cubage become smaller because of vane rotation, as result, oil is impelled out under the vane pressure. When rotor turns continually oil in tank is sucked into pump and then discharged out ceaselessly to form a stable flowage. Pump flowage formula is showed in Diagram 2-1.

As for video-on-demand, News Corporation plans to store as many popular television shows and movies as it can on digital video recorders for instant playback. For more obscu fuel dispenser re material it will provide a broadband option. In Britain it took a first step in this direction on January 10th by allowing its subscribers to download films and sports highlights from the internet on their home PC free of charge. The most challenged of all of News Corporation s divisions is its newspaper business, which contributes one-fifth of its operating income. Newspapers are suffering from the internet more than the rest of “old?media, as classified advertising moves online and young people are using the net to get their news. No other media conglomerate owns newspapers in any significant number. Mr Murdoch recently sold the educational supplements of the British Times because he thought they were too dependent on classified advertising. But he does not appear to have any bolder solution. “Despite his speech, only a tiny fraction of News Corporation s energy appears to be going into securing its newspapers future online,?says Simon Waldman, director of digital publishing at the Guardian. In Britain the Murdoch-owned Sun, Times and News of the World together attracted 6.7m unique visitors in November 2005, only the same as the Guardian alone, and far fewer than the 21.4m who visited fuel dispenser the news site of the BBC, a publicly funded broadcaster. Many investors would like Mr Murdoch to reduce News Corpo fuel dispenser ration s exposure to newspapers. The main reason that he does not, says a shareholder, is that he s “an empire builder who refuses to sell things? This investor would also like the company to sell its television stations, which are struggling to grow because America s advertising market is mature and because advertisers are moving money away from TV to the internet. One executive at the company agrees that “we ve never been very goo
