Thermoplastic polymer mixture
TLDR
In this article, flame resistant, thermoplastic polymer mixtures are described which contain two ethylene vinyl acetate copolymers having different vinyl acetates contents, an ethylene-propylene copolymer and an acrylate copolymmer.Abstract:
Flame-resistant, thermoplastic polymer mixtures are described which contain two ethylene vinyl acetate copolymers having different vinyl acetate contents, an ethylene-propylene copolymer and an acrylate copolymer. The flame resistance of the mixtures is effected by aluminium hydroxide as filler, which has a specific surface area of less than 10 m /g.read more

Driving circuit of electric shutter using permanent magnet
Yasuo Ishiguro,Osamu Oba +1 more
TL;DR: In this paper, the authors proposed to reduce the racing of shutter second time by flowing the current of the exent of negating the attraction force of a permanent magnet to a coil to put its iron piece in a stable position at the shutter setting then breaking the current supply to let the iron piece be completely attracted.
