Title: Noise suppression device
Inventor: SASAI AKIO
IPC: H04N5/21
Filed: 1990-04-05
Abstract: PURPOSE:To reduce appearance of a moving area with a small frame difference on a screen as after-image by detecting the correlation of a noise suppression signal in horizontal and vertical directions and withdrawing noise suppression to a moving area having the correlation in the horizontal or vertical direction. CONSTITUTION:A correlation detection circuit 7 detects a correlation in horizontal and vertical directions from a signal resulting from converting a frame difference outputted from a fixed storage circuit 4 nonlinearly. When the correlation detection circuit 7 discriminates the signal as noise and is supplied to a switch circuit 10 as a detection signal, the circuit 10 selects an output signal of a 2nd delay circuit 9, and a digital video input signal ei from an input terminal 1 is fed to a 1st delay circuit 8 to apply time compensation for the correlation detection circuit 7, from which the result is outputted, A 2nd subtractor circuit 5 subtracts an output signal of the switch circuit 10 from an output signal of the 1st delay circuit 8 and a digital video output signal eo in which noise is suppressed is outputted externally from an output terminal 6. Thus, the appearance of a moving area with a small frame difference on a screen is reduced as after-image.

Title: Method and device for processing image
Inventor: SEGAWA NOBUYUKI
IPC: H04N7/18
Filed: 1992-04-13
Abstract: PURPOSE:To execute an image processing scarcely influenced by an external light and a surface reflection, and to exactly execute a recognition/decision processing. CONSTITUTION:An image pickup angle of the same processing object 1 by video cameras 3, 4 is varied, images of plural processing objects 1 whose image pickup angles are different from each other are converted to electric signal by the video camera 3, respectively, misalignment of the processing object 1 in plural electric signals from its video camera 3 is corrected, and thereafter, an addition processing is executed. As a result, by image data of plural processing objects 1 whose image pickup angles by the video camera 3 are different from each other, the influence by an external light and a surface reflected light can be softened. Accordingly, even in the case that the processing object 1 has the specular surface or the surface being similar to the specular surface, and the processing object is influenced greatly by an external light and a surface reflected light from other part than a camera and an illuminating system, the processing object can be inspected or recognized exactly.

Title: Semiconductor integrated circuit device
Inventor: MURATA MASATAKA
IPC: H01L27/04
Filed: 1993-04-20
Abstract: PURPOSE:To obtain a resistor with high precision, little fluctuation but high resistance without increasing an occupied area by depositing a conductive layer along recesses and protrusions which recesses or protrusions provided on the main surface of a semiconductor substrate form perpendicular to the substrate. CONSTITUTION:Recesses and protrusions are formed on the main surface of a semiconductor substrate 1 by a plurality of protrusions 2 in a direction perpendicular to the substrate 1. Along these recesses and protrusions, a conductive layer of polycrystalline silicon 4 is formed by CVD and the conductive layer 4 has a displacement in the perpendicular direction by the recesses and protrusions through a plurality of recesses 2. As a result, the conductive layer 4 has a layer length increase which is obtained through multiplication of a perpendicular displacement by the number of recesses and protrusions and the overall resistance increases. Consequently, without increasing an occupied area, a resistor of high precision, little fluctuation, hardly susceptible to noise, and a large resistor can be formed in a semiconductor integrated circuit device.

Title: Speed ratio control device for continuously variable transmission for car
Inventor: GOUNO TAKESHI
IPC: F16H61/662
Filed: 1983-05-26
Abstract: PURPOSE:To improve an efficiency of an acceleration by increasing a changing speed of a speed ratio adjusted by a speed ratio adjusting means in accordance with the rise of an actual revolution speed of an engine to increase the efficiency of response at the time of the acceleration. CONSTITUTION:A target revolution speed is decided by a relation obtained in advance by a target revolution speed deciding means based on a requested load detecting signal having an engine revolution speed detecting means and an requested load detecting means. A speed ratio of a continuously variable transmission is adjusted by a speed ratio adjusting means based on a deviation between the target revolution speed deciding means and an actual revolution speed. This speed ratio is controlled by a speed ratio changing speed control means to be made bigger in accordance with the rise of the engine revolution speed from the relation obtained in advance. In other words, the speed ratio changing speed is made bigger to obtain a high response output as it goes in a higher revolution area where an output change of the engine against the target revolution speed change is small.

Filed: 1984-05-10
Abstract: PURPOSE:To effectively perform a starting operation of a speed servo motor at power source turning time and motor locking time by not only detecting the peak value of a sawtooth wave generator output as a frequency/voltage conversion output but also utilizing as the detection of the stopping state of the motor. CONSTITUTION:The output D of a sawtooth wave generator 4 gradually rises when a power source is turned ON and a motor is locked, a transistor 12 is turned ON, an output E becomes H, and an analog switch 10 becomes ON. Thus, the output D at that time is supplied to a holding capacitor 8. When a motor 1 is started, a pulse generator 3 generates pulses B, C. The generator 4 outputs a sawtooth wave D in response to the pulse output C. Since the output D is low in the steady state, the transistor 12 is turned OFF, and an analog switch 10 supplies the peak value of the sawtooth wave E by the pulse output B to the capacitor 8.

Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording medium which makes it possible to obtain stable reproduction output and improves corrosion resistance, as well as a process for producing the same, and a method for specifying the thickness of the magnetic recording medium. SOLUTION: A metallic film consisting of copper is formed at an arbitrary thickness on a polymer film and a magnetic material metallic layer is formed at, for example, 50 nm, on this metallic film. A carbon protective film is then formed at, for example, 8 nm on this magnetic material metallic layer, by which a magnetic tape is completed. The film thickness of the carbon protective film is specified in such a manner that the surface electric resistance of the magnetic tape formed by changing the thickness of the metallic film and repeating the magnetic tape forming stage attains <=200 Ω/sq. The metallic film consisting of the copper having the film thickness specified in the manner described above is formed under the magnetic material metallic layer, by which the magnetic tape is completed.  The static electricity generated by friction between an MR element and the magnetic tape is thereby reduced and the dielectric breakdown of the MR element is prevented. Consequently, the stable reproducing output is obtd.
