Title: Method for dephosphorizing molten iron containing chromium
Inventor: USUI TSUTOMU
IPC: C21C7/076
Filed: 1984-12-27
Abstract: PURPOSE:To dephosphorize efficiently molten iron contg. Cr at a low cost with no oxidation loss of Cr by adding a CaO-NaF flux to the molten iron after desiliconization to a prescribed concn. of Si. CONSTITUTION:Molten iron is desiliconized to lower the concn. of Si to <=0.10%. This desiliconized molten iron is dephosphorized by adding a CaO-NaF2 flux obtd. by mixing CaO with CaF2. By this method, efficient dephosphorization can be carried out with no practical oxidation loss of Cr in a wide concn. range of carbon including <=5% carbon in low carbon steel. Since the CaO-NaF flux is less expensive than a conventional dephosphorizing flux, the refining cost can be reduced.

Title: Fsk modulation circuit
Inventor: ISHIGURO KAZUHISA
IPC: H04L27/12
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To provide an FM modulation circuit where a frequency characteristic of a low frequency range is improved. SOLUTION: Input data are fed to a VCO 5 in an FM modulation circuit consisting of a PLL and a reference frequency of a reference oscillator 6 is changed by the input data. A loop gain of the PLL circuit is set larger at low frequencies and smaller at high frequencies. Thus, in the case that the frequency of the input data is low, the frequency of the VCO 5 is changed by changing the reference frequency, and in the case that the frequency of the input data is high, the frequency of the VCO 5 is changed by applying the input data to the VCO 5. The oscillating frequency of the VCO 5 is changed and FM modulation is attained.

Filed: 1987-11-06
Abstract: PURPOSE:To trace many buoys simultaneously and to efficiently proceed with the work of buoy tracing by giving variation to the chromaticity of the buoys to be traced and changing a threshold level in a cursor. CONSTITUTION:Now, the cursor contains two buoys A and B, the chromaticity of the buoy A is assumed to be '100' and the chromaticity of the buoy B to be '90'. First, as shown in a step S1, when they are binarized with the threshold level of the chromaticity '100', the part of the buoy A becomes '1' and the part of the buoy B becomes '0'. When other parts are white (225), they become '1'. Next, as shown in a step S2, when they are binarized with the threshold level of the chromaticity '101', both the part of the buoy A and the part of the buoy B become '0' and the other parts become '1'. In the decision of a step S3, the results of the binarizations by the two threshold level becomes '1' and '0' only about the part of the buoy A and thus, the coordinates of the buoy A can be recognized.

Filed: 1986-11-21
Abstract: PURPOSE:To keep the surface of a dielectric drum satisfactory by coating the surface of a member disposed in the vicinity of a corona ion generator and an image carrier with a fluoro resin. CONSTITUTION:A recording head 3 and the corona ion generator in a destaticizer 7 generate many ozones in operation. The ozone may reside in a gap between recording head supporting member 2, the recording head 3 and the dielectric drum 1, and it may corrode the recording head supporting member 2 and help corona products to attach. In order to prevent such possibility, the surface of the member disposed in the vicinity of the corona ion generator and the image carrier is coated with a fluoro resin. Thus the corrosion by the ozone and the generation of corona products never take place, whereby the surface of the dielectric drum can be kept satisfactory.

Abstract: PURPOSE: To produce a prescribed message by utilizing a PIP circuit. CONSTITUTION: An output of a message generating circuit 10 and an output of an input selector switch 2D are connected to an input of a PIP section 30, that forms slave/master screens and a Y/C-processing section 40, is connected to an output side of the PIP section 30.
