Beijing time on September 30, according to Bloomberg News, as of the close of US stocks on Thursday, IBM shares rose 1.62 US dollars to close at 179.17 US dollars, the market value of 214 billion US dollars; Microsoft shares fell 13 cents to close at 25.45 US dollars, the market value USD 2132. This is also the first time that IBM's market value surpassed Microsoft's since 1996, ranking second in the market for technology companies, behind Apple. In May of this year, IBM's market value temporarily transcended Microsoft during trading. In 2000, Microsoft’s market value was three times that of IBM.
Six years ago, IBM CEO Sam Palmisano sold the PC business to Lenovo and focused on the software and services business. As PC growth slowed down, Microsoft’s Windows and Office businesses grew slowly. The company replaced Apple’s position as the world’s highest market-cap technology company last year. At present, Apple’s market value is US$442.9 billion.
This year, IBM's stock price rose 22%, while Microsoft's stock price fell 9% (Compile / Banyan Tree)
Semiconductor Fuse and Ferrite
Fuse refers to an electric appliance that, when the current exceeds the specified value, melts the fuse and disconnects the circuit with the heat generated by itself.When the current exceeds the specified value for a period of time, the fuse melts and disconnects the circuit with the heat generated by the fuse itself.A current protector made from this principle.The fuse is widely used in high and low voltage power distribution system and control system as well as power equipment.
Ferrite is a metal oxide with ferrous magnetism.As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of single metal or alloy magnetic materials, and it has higher dielectric properties.Ferrite magnetic energy also shows high permeability at high frequencies.As a result, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current.Due to the low ferrite magnetic energy stored in the unit volume, saturated magnetic induction strength (Bs) and low (usually only pure iron 1/3 ~ 1/5), and thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.
