Title: High definition television signal reception circuit
Inventor: SUZUKI NORIHIRO
IPC: H04N7/015
Filed: 1988-03-25
Abstract: PURPOSE:To prevent leakage from a C signal to a YH' signal at the time of a still picture by cancelling the regeneration of the YH' signal in a color vertical edge part. CONSTITUTION:The output of the YH' signal and the output of a CF signal to be obtained through a frame comb-line filter 1 and a field comb-line filter 3 are passed through an absolute value device 10 and a comparator 11 in the processing part of the still picture and '1' is outputted when the CF signal is greater. A composite signal is passed to an LPF 12 and an edge is detected with the use of a vertical edge detector 13. The vertical edge is detected from the luminance signal of a low frequency area and the extraction of the YH' signal is prevented in the edge part. Thus, the leakage from the C signal to the YH' signal can be removed and a picture quality deterioration by a crosstalk can be prevented.

Filed: 1992-02-19
Abstract: PURPOSE:To decarburize a molten steel down to an extra-low-carbon region without the loss of the Mn therein in the above-mentioned method for decarburizing the molten steel with a vacuum degassing device by specifying the pressure in a vacuum chamber, blowing an inert gas contg. a specific amt. of oxygen to the surface of the molten steel and changing the oxygen concn. in the gas. CONSTITUTION:The atmosphere pressure in the vacuum chamber is maintained at >=5000 to 40000Pa in melting of the high-Mn steel having >=1 mass % Mn concn. A gaseous mixture of the inert gas, such as Ar, contg. the oxygen up to 95vol.% is blown to the surface of the molten steel by a top blowing lance.

The molten steel does not substantially cause reflux any more and the degassing effect is no longer expected if the atmosphere pressure exceeds the upper limit. There is substantially no effect of the dilution by the Ar and the oxidation loss of the Mn and iron is significant when the oxygen concn. in the blowing gas exceeds the upper limit.

CONSTITUTION:The information is written by using light having a wavelength with higher optical absorption of the recording layer at writing of optical information in the recording/ reproduction to/from the optical information recording medium consisting of the monomolecular accumulated film, while the information is read by using light having a wavelength with higher light reflectance of the recording layer at reading of the optical information. That is, in using the optical information recording medium for recording/reproduction of the information, the information is recorded by physical changes, chemical changes caused by the interaction of light and heat with the recording layer due to the irradiation of the write layer light or the optical characteristic changes attended with the change in the molecular aggregated structure. On the other hand, the information is reproduced by irradiating the read laser light to sense the change in the reflectance of the recording layer.
