Title: Video signal processor
Inventor: NITTA YOSHIRO
IPC: H04N11/20
Filed: 1989-11-28
Abstract: PURPOSE:To easily identify that an output signal is a color video signal already processed of EDTV by providing identification signal insertion means and superimposing a prescribed identification signal onto a color video signal processed by level compensation processing for a vertical blanking period and outputting the result. CONSTITUTION:An identification signal Sid outputted from an identification generating circuit 15 is fed to an adder 14 via a gate 16. On the other hand, a video signal Sed is fed from a terminal 11 to a synchronizing separator circuit 17, in which horizontal and vertical synchronizing signals are separated and fed to a gate pulse generating circuit 18, from which a gate pulse in a proper timing is formed and fed to the gate 16 as a control signal. Thus, a sinusoidal wave signal of a chrominance subcarrier frequency is inserted as the identification signal Sid to, e.g. 15th horizontal scanning period H15 of each vertical blanking period in addition to a burst signal Sb. Then the video signal Sed with the identification signal Sid inserted thereto is led from an output terminal 12 and recorded on a VTR 1.

Title: Coupling system for composite mode-composite signal source picture signal
Inventor: YOHAN HENDORITSUKU ANTOON HERI
IPC: H04N21/2365
Filed: 1993-12-08
Abstract: PURPOSE: To alternately generate a composite picture in pixel sequence by selectively plotting signal source pixels, which are offered by signal sources different by video modes, on the final target pixel of the composite picture. CONSTITUTION: Signal source pixels are encoded to digital words to perform plotting, and each digital word having color information and a video mode identifier is used to decode a color information part, and it is processed so as to constitute a composite picture. Under the control of graphic data explained as a video mode identifier or a color, the composite picture is coupled to computer graphic data of a video signal group. When the color of the final target picture element is determined by one video signal source in a video signal source group, graphic data is used to select a proper decoder. In this system, partial constitution and easy merging with a processing controller 40 are possible.

IPC: C01G49/00
Filed: 1990-11-14
Abstract: PURPOSE:To obtain a ferrite magnet which is a permanent magnet having a high sigmas (intensity of magnetization) by adding powder of a compound containing Sr to powder of a strontium W-phase type hexagonal metallic oxide at the specific ratio in terms of SrO and by shaping the mixture in a magnetic field and by sintering it at the specific temperature. CONSTITUTION:In order to add a compound containing Sr to a metallic oxide, fine powder of SrO may be directly added. Usually, however, a compound of strontium and carbonate or nitrate or sulfate is added. When the compound of strontium and carbonate or nitrate or sulfate is added, the amount of the compound added is decided in terms of SrO. It is important that the amount of the compound containing Sr which is to be added is 1-5wt.% of the metallic oxide, preferably 2-4wt.%, in terms of SrO. The shaped cylindrical compact is again calcinated at 1,100-1,200 deg.C, preferably 1,125-1,200 deg.C, for 0.5-2 hours to sinter fine powder of the metallic oxide in the compact. Thus, a ferrite magnet is obtained.

Title: Correcting method of image density
Inventor: NAKAGAMA KIYOHARU
IPC: G03G15/20
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To automatically correct the fluctuation of the density of an image between the time of starting to use an image forming device and its operation period by detecting the temp. of a fixing unit, just after power is supplied or an energy saving mode is cleared and correcting gradation, when the detected temp. is of a fixed temp. or below. SOLUTION: When the power is turned on or the energy saving mode is released, a control part CPU checks that the fixing temp. of the fixing unit 19 is of the fixed temp. or below, that is, makes a decision by the fact that the temp. of the part of a fixing roller 19a detected by a temperature sensor SH provided in contact with or near the fixing roller 19a of the fixing unit 19 is <=50 deg.C or not. When the detected temp. is not <=50 deg.C, it is judged that a downtime after the pervious operation is not so long, so that the image is formed with the present gradation reference value, without correcting the gradation. When the detected temp. is <=50 deg.C, it is judged that the downtime after the previous operation is so long, so that a gradation correcting process is executed and the image is formed with a gradation correction value decided in this process.
