Description
Technical field
The present invention relates to automation forms field, more particularly to a kind of power windows automatic closing system.
Background technology
On April 5 nineteen fifty-nine, first high-speed railway Tokaido the Shinkansen truly is in Japanese break ground and start building in the world
Work, built by 5 years, completely completed to lay a railway track in March, 1964, July in the same year is completed, and is formally open to traffic on October 1st, 1964.East
Seaway the Shinkansen is originated from Tokyo, by way of Nagoya, and the ground such as capital of a country is eventually to (new) Osaka, and 515.4 kilometers of total length, overall trip speed is high
Up to 210 kilometers/hour, being open to the traffic for it indicates the epochal arrival of world's high-speed railway.Then French, Italy, moral
State builds high-speed railway one after another.1972 after Tokaido the Shinkansen, Japan built again adret, northeast and on it is newer dry
Line；France has built southeast TGV lines, Atlantic Ocean TGV lines；Italy has built Rome to Florence.Headed by Japan
Building up for generation high-speed railway, has promoted the balanced development of regional economy along the line, has promoted real estate, industrial machinery, steel energetically
The development of the related industries such as iron, reduces influence degree of the communications and transportation to environment, and Railway Market share is significantly gone up, enterprise
Economic benefit is clearly better.
The most of Europe developed countries such as France, Germany, Italy, Spain, Belgium, Holland, Sweden, Britain, greatly
Scale builds the state or transnational high-speed railway, has gradually formed High-speed Railway Network in Europe network.The construction of current high-speed railway is high
The need for tide, not exclusively railway improve internal corporate benefit, the need for being more national energy, environment, traffic policy.
