Title: Hue control circuit for color video signal
Inventor: BUINSENTO KAARU HARADAIN
IPC: H04N9/64
Filed: 1990-04-20
Abstract: PURPOSE:To attain hue control with comparatively few circuit components by using 2 multipliers and one adder so as to apply hue adjustment. CONSTITUTION:A video signal is received at an input terminal 10 in a form of color difference samples Cb, Cr in multiplex transmission alternately. The video signal is multiplied with a factor cosphi at a 1st multiplier 14 and the result is fed to an adder 20, where phi is an objective hue adjustment. On the other hand, the sequence of the video signal is inverted by a multiplex transmission sequence inverting circuit 11 and the sequence corresponding to the samples Cb, Cr is inverted and factors -sinphi and +sinphi selected alternately are multiplied at the 1st multiplier 26 and the result is fed to the adder 20. The multiplied signals are added by the adder 20 to output a color difference sample subjected to hue adjustment Hb=Cbcosphi-Crsinphi and Hr=Cbsinphi+Crcosphi.

Title: Oscillation stopper for material to be painted in automatic painting machine
Inventor: KOMATA TAKASADA
IPC: B05C13/00
Filed: 1983-06-11
Abstract: PURPOSE:To enable quick and continuous painting of a large amt. of materials to be painted by disposing an oscillation stopper which is engaged with the material conveyed by a conveyor or a hanger suspending said material and stops the oscillation thereof. CONSTITUTION:A conveyor 4 is operated to convey and supply successively a material to be painted which is suspended to a hanger 16 and when the conveyor 4 is stopped in a painting position, the material is going to oscillate in the conveying direction together with the hanger 16 owing to inertia. However, the left end of the movable piece 21 of an oscillation stopper S is retrained in the contact position of the hanger 16 with the material held still in the prescribed painting position so as to intersect orthogonally with the conveying direction of the conveyor 4 and therefore the hanger 16 engages with the piece 21 and is thus held still in the prescribed position, by which the oscillation of the material to be painted is quickly stopped. When the painting is completed in this state, the right end of the piece 21 is depressed downward and is disengaged from the hanger 16.

Title: Switching method for antenna
Inventor: KITAMURA MITSUAKI
IPC: H04L1/06
Filed: 1993-04-30
Abstract: PURPOSE:To secure received radio wave quality and to improve reliability by excluding useless antenna switching operations as much as possible by performing decision corresponding to received radio wave strength and the code error detected result of a received signal when controlling the switching of an antenna. CONSTITUTION:The received radio wave strength of antennas 11 and 12 under receiving radio waves is always monitored by a detector 14 and when the received radio wave strength is lower than a second level, a detector 16 inspects whether any code error is generated in the received signal or not. When no code error is generated as a result, the antennas are not switched but a normal receiving state is kept. When the code error is generated, an antenna switching state is started, a switching operation 13 to the next antenna is performed under the control of a controller 15, and it is investigated whether the radio wave strength is higher than a first level or not. When the strength is lower than the first level, the next antenna switching is performed again. When the strength is higher than the first level, however, it is investigated whether any code error is generated or not and when no error is generated, processing finishes the antenna switching state and returns to the normal receiving state.

Title: Prevention of camber and bend of sheet in sheet rolling
Inventor: TAMAGAWA TOSHIYUKI
IPC: B21B37/28
Filed: 1984-05-25
Abstract: PURPOSE:To prevent effectively the camber and bend of a sheet by subjecting the part of work rolls corresponding to the elongating side of the camber or bend to surface roughening. CONSTITUTION:A relative elongation is eventually generated in the right part when a material 2 to be rolled bends toward the left with respect to the rolling direction. A controller 16 moves thereupon a cutting tool 11 by the output signal from a bend detector 12 to press the tool to a work roll 1 thereby grooving finely the outside circumferential surface thereof. The fine groove increases the coefft. of friction on the outside circumference of the roll 1, by which the elongation of the material 2 is suppressed and the bend of the material 2 is consequently corrected.

Abstract: PROBLEM TO BE SOLVED: To regenerate finely changing amplitude information with high fidelity without being affected by frequency shift due to Doppler effect, by mixing a receiving signal with oscillation signals different in frequency, and extracting a difference frequency signal from the two mixed frequency signal. SOLUTION: Mixer circuits 5, 5' mix a receiving signal (a) having a frequency f1 with oscillation signals which are supplied from local oscillator 6, 6' and have different frequencies f3 , f4 , and generates sum frequency signals f1 +f3 and f1 +f4 and difference frequency signals f1 -f3 =F1 and f1 -f4 =F2 . Filter circuits 7 and 7' pass a signal (e) of the difference frequency F1 and a signal (f) of the difference frequency F2 , respectively. A multiplier circuit 11 forms a sum frequency F1 +F2 and a difference frequency F1 -F2 =Fa. By a filter circuit 12, a signal (g) of the difference frequency Fa is only sent to a root circuit 13. An amplitude signal which has been squared by multiplication is returned to the original state. The signal (g) is converted to a signal in an audible bandwidth, and outputted to an amplifier 14. Thereby frequency shift due to Doppler effect is canceled.
