IPC: G11B11/10
Filed: 1989-11-13
Abstract: PURPOSE:To increase a Kerr rotating angle without having the problem of oxidation by laminating >=2 layers of composite layers consisting of magnetic films contg. hexagonal ferrite particles and dielectric films on a transparent substrate and providing a reflecting layer on the outermost layer thereof. CONSTITUTION:The magnetic film on the transparent substrate is formed by an ordinary coating method. Since this film consists of a coated film type contg. magnetic material particles, the magnetic film having the specified compsn. is easily formed.

The dielectric film is further formed on the magnetic layer and >=2 layers of the composite layers consisting of these two films are laminated. The light reflecting layer is provided on the outermost layer. The large Kerr rotating angle is obtd. in this way and the reproduced output as the magneto-optical recording medium is greatly improved.

Title: Method for working martensitic heat resistant steel
Inventor: NISHIUCHI SHOHACHI
IPC: C22C38/18
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To unnecessitate heating equipment and to attain the reduction of the cost and environmental improvement by annealing martensitic heat resistant steel to reduce its hardness and thereafter executing cold working in a specified temp. range. SOLUTION: Annealing before cold working is executed preferably at 750 to 1,100 deg.C two times. Then, the cold working is executed at a room temp. to 150 deg.C. As the compositional ratio of martensitic heat resistant steel, the one in which the content of C is 0.35 to 0.55 wt.% and the content of Cr is 5 to 12 wt.% is suitable. Moreover, since in the cold working, in a material, heat generation occurs in accompany with the deformation, and its temp. increases, by removing this heat generation with a chiller or the like, its upsetting ratio can be increased. Also, in the case that the cold working is executed by a plurality of stages using different metal molds instead of using a chiller, since cooling is executed at the time of replacing the mold, the critical upsetting ratio becomes higher than that in the case of working by one stage.

Abstract: PURPOSE:To simply adjustment of the frequency and duty of a rectangular signal by holding the peak voltage of a charging circuit by a peak holding circuit and controlling the discharging of a charging and discharging circuit with the output voltage of the peak holding circuit. CONSTITUTION:The discharging circuit discharges the charging circuit 1 when the output voltage of the peak holding circuit 2 exceeds a 1st predetermined reference voltage V1. Consequently, the charging and discharging waveform of the charging circuit 1 is a triangular wave whose peak value is equal to the reference voltage V1. Then a comparing circuit 4 compares a 2nd reference voltage V2 obtained by dividing the reference voltage V1 by resistances with the output voltage of the charging circuit and outputs a rectangular wave signal. The frequency of the rectangular wave signal is determined by the value of the 1st reference voltage V1 and the duty is determined by the value of the 2nd reference voltage and variable between 0 and 100%. Consequently, the frequency and duty of the rectangular wave signal can be adjusted independently and easily.
