Title: Amorphous core for common mode choke
Inventor: YOSHIZAWA KATSUTO
IPC: C22C45/02
Filed: 1985-06-25
Abstract: PURPOSE:To obtain an amorphous core for common mode choke, which is superior in characteristics to a low-level noise to a ferrite core for common mode choke and is equal or more with a Co group amorphous core for common mode choke in stability with time and is superior to the Co group amorphous more, by a method wherein an amorphous alloy having a specific composition is used as the material for the amorphous core for common mode choke. CONSTITUTION:An amorphous alloy having a composition, which is shown by a compositional formula =Fe100-x-y-zMxSiyBz (where the M is at least one kind of an element to be chosen out of the group of Ti, Zr, Hb, V, Nb, Ta, Cr, Mo, W, Mn, and Ni) and has the relations of 0.1<=x<=8, 10<=y<=18 and 8<=z<=9.5 (atomic %), is used as the material for the amorphous core for common mode choke. The Fe is essential in the composition and is needed for enhancing the magnetic properties of the amorphous alloy. The M is an essential element for improving the variation with time and for improving the noise attenuation characteristic. However, when the content (x) of the M is not more than 0.1 atomic %, the M has no effect on the improvement of the variation with time and the improvement of the noise attenuation characteristic and when the content (x) is larger than 8 atomic %, a marked drop in the saturated magnetic flux density and the Curie temperature is brought. Accordingly, it is not desirable for the content (x) to exceed 8 atomic %. When the amorphous alloy having a board thickness of 20mum or less is used, the noise attenuation characteristic of a high frequency (500kHz or more) is especially improved. As a result, more favorable results can be obtained.

Abstract: PURPOSE:To suppress the spread of a transmission spectrum by extracting and storing a phase change of a high frequency signal from an output of a transmitter and giving a phase change in advance to a reference high frequency signal being an input signal to the transmitter with a modulation signal formed from phase change information. CONSTITUTION:An amplitude limiter 1 limits the amplitude change of part of a transmission output from a transmitter 100 and outputs a signal whose amplitude is arranged to a phase detector 2. Then a voltage signal corresponding to a phase difference to a reference high frequency signal fed from a reference frequency signal generator 104 is outputted and digitized and a voltage stored in a memory 3 is read in response to a transmission trigger. It is amplified and smoothed by an amplifier circuit 4 and fed to one input of an adder 6 while the polarity is inverted negatively and an error with a reference voltage of positive polarity is obtained. The error signal is fed to a phase modulator 5 as a modulation signal, the phase modulator 5 changes the phase of the reference high frequency signal based on the error signal and outputs it as an input reference high frequency signal of the transmitter 100. Thus, the spread of the transmission spectrum is limited.

Abstract: PURPOSE:To improve the dimensional accuracy by connecting a plurality of plate members at their connection parts and providing a thin wall part at a part of the connection parts. CONSTITUTION:A resin molded body is formed of two plate members 2a, 2b. The end of the plate member 2b is put into contact with the other surface of a plate member 2a and they are connected at their connection parts 3.
