IPC: H01F1/12
Filed: 1982-09-18
Abstract: PURPOSE:To obtain an alloy having improved hot workability and enabling the easy manufacture of the tip of a magnetic head by adding Ru, Ir or Pt as well as specified amounts of Ti, Zr and Ge as secondary components to a high magnetic Fe-Si-Al material. CONSTITUTION:To an alloy consisting of, by weight, 4-12% Si, 3-8% Al and the balance essentially Fe are added 0.1-2.0% Ti, 0.02-3.0% Zr, 0.05-2.0% Ge and 0.1-3.0% in total of one or more among Ru, Ir and Pt. Ti and Zr prevent grain coarsening and edge cracking during working at high temp. Ge improves the workability at high temp. and prevents chipping during mechanical working at room temp. Ru, Ir and Pt inhibit the formation of an oxide film at high temp. Accordingly, an Fe-Si-Al alloy having high magnetic permeability and undergoing no deterioration in the magnetic characteristics is obtd. The alloy is easily hot worked without causing surface oxidation.

Title: Magnetic recording and reproducing device
Inventor: HONJO MASAHIRO
IPC: G11B20/02
Filed: 1984-07-31
Abstract: PURPOSE:To prevent the deterioration of a reproduced picture due to mixing of a luminance signal to a chrominance signal by detecting the vertical correlation of the chrominance signal and limiting a recording or reproducing band of the luminance signal when the vertical correlation is weaker than the prescribed value. CONSTITUTION:A Y signal (b) and a C signal (g) are separated from an input signal (a) by a comb-shaped filter 2. On the other hand, the input signal (a) and a component of 3.58MHz of 1H delayed signal pass through BPFs 25 and 24 to turn out to be signals (c) and (d), respectively, and transmitted to a comparator 26. It compares the amplitude or phase of the signal (c) with those of the signal (d), and generates the signal in accordance with the difference. A band limiting circuit 27 inputs a signal (e), and limits the band of the Y signal at a high level. The band limiting circuit 27 is composed of an LPF or band obstructing filter. Namely, when the signal (e) is at a high level, the Y signal band is limited, and the Y signal (b) becomes a Y signal (f), whereby noises never occur. This can be obtained in a reproduction system of a VTR.
