Title: High-silicon steel sheet having excellent magnetic characteristic
Inventor: TAKADA YOSHIICHI
IPC: H01F1/16
Filed: 1986-06-04
Abstract: PURPOSE:To improve the magnetic characteristics of a high-silicon steel sheet by limiting the content of O including O in the surface oxide film of the high-silicon steel sheet specified in the content of Si and sheet thickness to a specific range. CONSTITUTION:The content of Si in the silicon steel sheet is specified to 4.0-7.0wt% and the content of O including O in the surface oxide film is specified to <=70ppm; further, the thickness of the silicon steel sheet is specified to 0.01-2mm. The excellent magnetic characteristics are stably obtd. by such silicon steel sheet. The Si is effective in improving the intrinsic electric resistance, decreasing an eddy current loss and decreasing an iron loss and is incorporated therein at >=4.0%. The magnetic characteristics, more particularly, the max. magnetic permeability are deteriorated if the content thereof exceeds 7.0%. On the other hand, the secure oxide film exists much in the steel sheet and hinders the transfer of the magnetic wall in the magnetization process of the iron sheet and changes the static magnetic energy around the same and therefore, a fresh magnetic domain is generated and the iron loss is increased if the content of the O exceeds 70ppm. The eddy current loss increases if the sheet thickness exceeds 2mm and conversely, the production cost increases considerably if 0.01mm.

IPC: H04B10/07
Filed: 1990-05-18
Abstract: PURPOSE:To eliminate an overhead due to a preamble by operating all stations synchronously with a distributed clock at all times so as to make a time required for clock recovery actually zero. CONSTITUTION:A phase locked loop oscillator 10 is operated by a master clock supplied from a clock photodetector 9 and uses its output and a pseudo data in a wavelength lambdaD is sent. The signal is made incident on its own data photodetector 11 via a star coupler 21 and an optical multiplexer and demultiplexer 8. A phase comparator 7 outputs an error signal to a phase shifter 6 to adjust the phase shifter so that a phase shift in an output of the phase locked loop oscillator 10 is within a prescribed value in terms of the error signal. Thus, the phase of a transmission data is synchronized with the master clock, the station exits from the startup mode, the phase shift of the phase shifter 6 is fixed and the monopoly right of a bus is left. The procedure above is repeated to each slave station (node) to take synchronization of the entire system.
