摘要:
An object of the present invention is to provide a novel propylene-based polymer capable of providing a propylene-based polymer with a good adhesion and coatability. The present invention lies in a propylene-based polymer having a propylene component with several characteristics including a weight-average molecular weight Mw from not smaller than 5,000 to less than 1,000,000 as measured by GPC, and Regio irregular units based on 2,1-inserted propylene monomer and/or 1,3-inserted propylene monomer present in its main chain and the sum of the ratio of regio irregular units based on 2,1-insertion and 1,3-insertion to all propylene insertions not smaller than 0.05%.

摘要:
A moving apparatus with a driving force assist mechanism traveled mainly by human power. This moving apparatus detects, in a non-contact manner, with respect to rotating portion such as traveling wheel, etc., rotation speed of the rotating portion to detect traveling state to deliver, from the driving force assist mechanism, assistant driving force corresponding to speed change information that a person who operates the moving apparatus intends to give on the basis of the detected traveling information to carry out traveling to thereby permit smooth traveling even in the case where traveling by only human power becomes difficult.
