Title: Low noise iron core excellent in magnetic characteristic
Inventor: NINOMIYA HIRONORI
IPC: H01F27/245
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To provide a low noise iron core having an excellent core loss characteristic, low-noise as well, excellent in mass-producibility and producible at a low cost, and having an excellent magnetic characteristic by using non- oriented silicon steel strips having a specific absolute value of DC magnetostriction, and laminating them. SOLUTION: An iron core A is composed of a laminated iron core formed by laminating a plurality of non-oriented silicon steel strips 1 punched into the shape of a cut core. Accordingly, noise is generated less compared with a wound iron core, since no resonance is generated. Besides, the Si content of the non-oriented silicon steel strips 1 is in a range of 4-7wt.%, to make the absolute value of the DC magnetostriction of the non-oriented silicon steel strips 1 to be used 1.5×10<-6> or less. Consequently, it becomes possible to obtain a low noise iron core having an excellent soft magnetic characteristic.  Since it is a cut core type laminated iron core by the use of non-oriented silicon steel strips 1 having an absolute value of DC magnetostriction of 1.5×10<-6> or less, in this way, it becomes possible to make the best use of both the merit of the non-oriented silicon steel strips 1 and that of the laminated iron core.

Abstract: PURPOSE:To enable supervision transaction and data-link communication by reading out predicted position information at a timing close to beam scanning time to a target, and by controlling a beam direction of an electron scanning antenna. CONSTITUTION:Position information of a target obtained from two times coverage investigation at all-call or supervision transaction at roll-call, are fed to a calculator 4 from a secondary supervision radar SSR transmitter/receiver 3, and the calculator 4 predicts and calculates a coming position where the target will move to and occupy within a time band of the roll-call. A plurality of timings within the time band are previously set forth as predicted timings, and predicted position information of the target at those timings are calculated in sequence and sent out to a memorizer 5. Then, the predicted position information at the closest timing to an arbitrary timing, is read out of the memorizer 5 and a controller 2 controls beam direction of an electron scanning antenna 1. In this way, the target is caught and data-link communication can be well conducted.
