為花紋而花紋

雖然現在情勢如此

但終究失去了原始的意義

MAPPER technology

MAPPER is working on a new, patented technology for making chips without a mask and using electron beams. This approach enables improved performance and reduces costs. The company´s major innovation is the use of one system through which more than 10,000 parallel electron beams can pass. MAPPER uses fibre-optics, which is capable of transporting a large quantity of information.

‘Writing’ circuits on to silicon wafers with electron beams can be compared with the way in which an image is formed in the cathode ray tubes of old televisions. In a television an electron beam is moved rapidly across the screen. As the electrons come into contact with the screen, which is coated with light-emitting material, a picture forms. In the MAPPER machine, by contrast, the image is not made visible but, as it were, stored in a film that is sensitive to electrons.

As molten iron cools down it crystallises at 1538°C (2800°F)into its delta allotrope, which has a body-centred cubic (BCC) crystal structure.

As it cools further its crystal structure changes to face centred cubic (FCC) at 1394°C, when it is known as gamma-iron, or austenite.

At 912°C (1674°F) the crystal structure again becomes BCC as alpha-iron also known as ferrite, is formed, and at 770°C (1418°F) (the Curie point, Tc ) the iron becomes magnetic as alpha-iron, which is also BCC, is formed.

As the iron passes through the Curie temperature there is no change in crystalline structure, but there is a change in the magnetic properties.

In unmagnetised iron, all the electron spins of the atoms within one domain are in the same direction.

However, in neighbouring domains they point in various directions and thus cancel out.

In magnetised iron, the electronic spins of all the domains are all aligned, so that the magnetic effects of neighbouring domains reinforce each other.

Although each domain contains billions of atoms, they are very small; each domain is about one thousandth of a centimetre across.

鐵的結晶

Martensite, named after the German metallurgist Adolf Martens (1850–1914), most commonly refers to a very hard form of steel crystalline structure, but it can also refer to any crystal structure that is formed by displacive transformation.

 It includes a class of hard minerals occurring as lath- or plate-shaped crystal grains.
