Title: Picture synthesizer
Inventor: YAMAMOTO KOJI
IPC: H04N5/272
Filed: 1990-04-19
Abstract: PURPOSE:To improve the synthesis picture by using a level key signal in addition to a chroma key signal and taking the correlation. CONSTITUTION:A chroma key signal D is obtained by segmenting a video signal B at a phase and a level of a color signal corresponding to a space by a chroma key section 2. Moreover, the video signal B is inputted to a level key section 3 to separate a sea scene and a sky scene by means of the brightness from the video signal B and a luminance component of the video signal B is sliced at a level VTH to obtain a level key signal E. The obtained chrome key signal D and level key signal E are inputted to a gate section 4, in which correlation is taken and even when the chrome key signal D is at an L level period, so long as the level key signal E is at an H level, a switch 1 is changed over to set an H level. Thus, even a part of the picture not completely synthesized by the phase and level of the chrominance signal only is corrected by the level key signal E detecting a prescribed luminance component of the video signal. Thus, complete picture synthesis is attained.

Title: Heating method
Inventor: ASANUMA TADASHI
IPC: C08J5/18
Filed: 1994-05-19
Abstract: PURPOSE:To easily heat various substances by covering a heated substance with resin moldings formed out of thermoplastic or heat resistant resin with acicular titanium oxide dispersed in resin, and irradiating a microwave to the substance. CONSTITUTION:A LABO PLASTOMILL R type mill (R) is used to thoroughly well mix 15g of acicular titanium oxide and 15g of polypropylene at 240 deg.C and, then, the mixture is pressed at 240 deg.C, thereby preparing a sheet of 2mm thickness. A sheet of 1mm thickness having the same polypropylene as above but not containing titanium oxide is sandwiched with the 2mm thick sheet so prepared and exposed to a microwave in a microwave oven for five minutes. Both sheets, when taken out and measured about temperature, are found to have the temperature of the 1mm thick sheet heated up to 130 deg.C. On the other hand, however, when only the 1mm thick polypropylene is placed in a microwave oven and similarly exposed to a microwave, the temperature thereof reaches approximately 28 deg.C and is almost free from a heating influence. Thus, various substances can be heated, when the acicular titanium oxide is dispersed in resin, and the industrial value of the substances can be enhanced.

Title: Stabilized power unit
Inventor: TATSUMI YUKIO
IPC: G05F1/56
Filed: 1994-04-20
Abstract: PURPOSE:To suppress the generation of a buzzing sound by an inductance element and prevent a chopper circuit from operating abnormally by adding a dummy load circuit which operates in the half period of a switching circuit to supply a dummy current the inductance elements. CONSTITUTION:The dummy load circuit 8 does not operate except when the switching circuit 4 is in the half period, and a switching element Q2 operates only when it is in a cutoff state in the half period to supply the dummy current ID. Then a coil current IA1 flows without intermittence even during the halt period DT of the switching circuit 4 and the coil current IA1 flows continuously during circuit operation. Consequently, a choke coil L is prevented from generating the buzzing noise. Further, the coil current IA1 is never break, so a rise in the output voltage of the chopper circuit 2 can be suppressed and the output voltage at an output point 2a does not rise when a discharging lamp 6 illuminates, so that a control part 5 can be prevented from malfunctioning.

Title: Magnetic recording medium
Inventor: KITAORI NORIYUKI
IPC: G11B5/66
Filed: 1993-04-07
Abstract: PURPOSE:To stably obtain high output from a low-frequency range to a high-frequency range by providing the magnetic recording medium with magnetic layers consisting of an MgO film formed on a base material and a film of a prescribed compsn. formed on this MgO film. CONSTITUTION:The magnetic layers consist of the MgO film formed on the base material and the alpha'-Fe16N2 film formed on the MgO film. The alpha'-Fe16N2 film is a compd. having an exceedingly high magnetic flux density but is hardly stably formable and, therefore, the MgO film is formed on the base material and this film is formed thereon. The formation of the magnetic layers is executed by maintaining about 10<-3> to 10<-5>Torr vacuum in a vacuum vessel, allowing a film to travel on a cooling can, forming the MgO film thereon, introducing gaseous nitrogen or air into an ion gun, generating active nitrogen and N<+> and simultaneously irradiating Fe with an Fe sputtering gun, thereby forming the alpha'-Fe16N2 film on the MgO film. The tape with which the high output from the low-frequency range to the high-frequency range is obtainable is thereby produced.

Title: Composite permeable membrane
Inventor: ICHINOSE TAKASHI
IPC: B32B5/32
Filed: 1979-08-20
Abstract: PURPOSE: To form a two-layered structure in which each layer consists of a differrent polymer and has a uniform thickness, by coating and impregnating a fibrous porous base material with a film-forming solution containing a polymer, forming the second layer upon the first layer from a film-forming solution containing a different polymer, and immersing the coated base material in an coagulating solution.  
     CONSTITUTION: A fibrous porous base material is coated and impregnated with a film-forming solution containing one polymer. Thereby, the first layer which is stable and substantially free from flow is formed. Immeadiately thereafter, a film- forming solution containing a different polymer is coated on the first layer. In this operation, diffusion between both the film-forming solutions occurs in only a partially limited area of the interface. Therefore, it becomes possible to form the second layer in a uniform thickness which is clearly distinguished from the first layer. When the coated base material is immersed in a congulation solvent, a composite permeable membrane comprising two different polymer layers is formed. Each of the layers has a substantially uniform thickness.

Title: Objective lens device
Inventor: TAKEMURA YASUHIRO
IPC: G11B7/1359
Filed: 1983-06-14
Abstract: PURPOSE:To always secure the coincidence between the optical axis of the laser light and that of an objective lens and to miniaturize an objective lens device, by shifting in parallel the light supplied with the center axis defined as an optical axis by means of >=1 pairs of parallel optical reflecting surfaces and making the light incident to the objective lens. CONSTITUTION:The position of a prism 17 is controlled and fixed to an objective lens holding barrel 26 so that the laser light beam supplied from the lower side of an objective lens device is reflected by reflecting surfaces 18 and 19 and then made incident to an objective lens 25. Therefore the surfaces 18 and 19 are turned together with the barrel 26 revolving around a support shaft 21. This eliminates a shift caused between the optical axis of the laser beam and that of the lens 25. In addition, the surfaces 18 and 19 can extract a signal showing the position relation between the focal point of the lens 25 and a reflecting matter set near the lens 25 by setting an angle phic at the critical value. This eliminates the need for the use of another optical system for detection of focal point.
