Title: Digital signal magnetic recording and reproducing device
Inventor: MATSUDA TOYOHIKO
IPC: G11B20/10
Filed: 1988-03-28
Abstract: PURPOSE:To reduce the deterioration of C/N at a demodulation side by increasing the accuracy of a selective costas loop by making the signal equiv. to a quadriphase phase modulation (QPSK) in 12 pieces from 8 pieces and reproducing a stabilized carrier wave. CONSTITUTION:The 5 bits/digital signal input to an input terminal 1 is output as the hexavalent signal of two systems of an I signal and Q signal by a mapping circuit 2. The signal equiv. to a QPSK component is converted into the polyvalent signal existing 12 pieces among 32 signals by the mapping circuit 2 and a carrier wave is reproduced by selecting the signal equiv. to how QPSK component from the signal demodulated by a carrier wave reproducing circuit 7. Since the signal equiv. to the APSK component in a 32 amplitude phase modulation (APSK) signals is made in the signal arrangement existing 12 pieces, the probability becoming the QPSK component is increased from 1/4 to 3/8, the accuracy of the costas loop is improved and a stabilized carrier wave can be reproduced. The C/N deterioration at the demodulation side can thus be reduced.

Title: Method and apparatus for treatment of converter slag
Inventor: MIURA YOUICHI
IPC: F27D15/00
Filed: 1980-06-03
Abstract: PURPOSE:To rapidly and safely treat converter slag by a simplified apparatus in which molten slag from converter is received in a slag receiving container, delivered to a cooling chamber, solidified by sprinkling water, and then discharged. CONSTITUTION:A self-running truck 6 is positioned beneath a converter 1, molten slag (a) is spread in a thin layer on a slag housing container 5, and slag (b) containing residual molten steel coming out in the later period of receiving is transferred to the container 7. The metal is separately housed in a metal housing container 7. Then, the truck 6 is moved to the cooling chamber 3, where water is sprinkled over the slag for quickly cooling it to cause shrinkage and cracking in the  molten slag (a) in a short time because of its thin layer. Thus, when discharging it  by inversing a hopper, the solidified slag becomes shattered and coarse lumps are  dropped and crushed by impaction in a grizzly. On the other hand, the metal housing container 7 is delivered to a metal treatment site. Thus, problems with radiation heat, steam, and dust in the treatment of slag can be eliminated.
