Title: Digital video signal processor
Inventor: MATSUMOTO YOSHIYUKI
IPC: H04N9/80
Filed: 1992-02-10
Abstract: PURPOSE:To attain the digital color demodulation of standard and non-standard video signals at a low cost by adding a correction by a digital arithmetic processing to a color modulation signal from a carrier chrominance signal based on the color modulation signal from a color burst signal extracted every time of horizontal scanning of the video signal. CONSTITUTION:A burst extracting circuit 42 extracts the color information YB and XB of the color burst signal demodulated by a digital color demodulating circuit 41 by each horizontal scanning of the video signal. A digital arithmetic processing part 43 performs the correcting processing by an arithmetic operation to the color information YC and XC of the carrier chrominance signal based on the color information YB and XB of the color burst signal. Thus, even when a phase deviation between a clock generated synchronously with the horizontal synchronizing signal of the input video signal, and the color burst signal of the input video signal is generated, the error of the color demodulation caused by the phase deviation can be automatically corrected based on the phase difference between the color burst signal and the clock CK.

IPC: B21B45/06
Filed: 1990-03-07
Abstract: PURPOSE:To correctly recognize the volume of the stored acid over the entire part and to improve consumption unit by adding the volume of the acid soln. carried over from a pickling tank and the volume of the acid soln. under circulation to the volume of the acid soln. in a circulating tank and controlling the feeding and discharging to and from the circulating tank. CONSTITUTION:The liquid level height and sp. gr. of the stored acid soln. are detected by a level gage 50 and a hydrometer 51 installed to the circulating tank 4 and the results thereof are applied to a computing section 60. The volume of the stored acid over the entire part of a 1st pickling unit is calculated as the sum of the volume of the acid soln. stored in the circulating tank 4, the acid soln. of the acid soln. carried over from the pickling tank 1 by the movement of a steel strip 10, and the volume of the acid soln. under circulation. The added volume of the stored acid is applied from the computing section 60 to a control section 61. Cascade pumps 40, 41 are driven by the operation of the control section 61 and the feeding and discharging of the acid soln. to and from the circulating tank 4 are executed, by which the volume of the stored acid is maintained approximately constant. The volume of the stored acid over the entire part is, therefore, correctly recognized regardless of the width and feeding speed of the steel strip.

Title: Coating method with slightly defective organic thin film by electrodeposition
Inventor: OKADA RYOJI
IPC: C25D13/00
Filed: 1990-03-12
Abstract: PURPOSE:To reduce the amt. of defects in a formed org. coating film by repeatedly carrying out electrodepositing and baking processes twice or more. CONSTITUTION:DC voltage is impressed between an electrical conductor as a body to be coated and an electrode in an aq. resin soln. to electrodeposit the resin on the surface of the body to be coated. The electrodeposited resin is then polymerized by baking and the resulting coating film is hardened. In the case where the hardened film has parts through which the base is exposed, e.g. pinholes and thin parts, electrodeposition and baking are carried out again. The resin in the soln. deposits selectively on the defective parts having high electrical conductivity and fills the parts. Since the resin does not deposit on the entire surface of the film, the thickness of the film is not increased by the 2nd electrodeposition and the body to be coated can be coated with an org. thin film free from defects. The desired final thickness of the film is <=10mum.

Title: Optical circuit element
Inventor: OOSHIMA KAZUYOSHI
IPC: G02B6/34
Filed: 1979-05-10
Abstract: PURPOSE:To realize a high performance minute optical circuit element in a simple constitution, by attaching a reflection type phase volume hologram to one end of a focusing rod lens having vertical end faces in the central axis. CONSTITUTION:Light of wavelength lambda1 is caused to enter optical fibers 8, 11, to form an interference fringe in a hologram recording material 7a. Light of wavelength lambda2 is caused to enter the optical fibers 8, 12 to overlap and record another interference fringe in the same recording material 7a. When the light of wavelength lambda1 is caused to enter from the fiber 8, the primary diffracted light is diffracted in a direction as if it were propagated from the fiber 11, and is converged in the position which is exactly in the imaging relation to the mounting position of the fiber 11. On the other hand, when the light of wavelength lambda2 is caused to enter the fiber 8, similarly, it is converged in the position located in the imaging relation to the  mounting position of the fiber 12. Therefore, when the optical fibers are fitted in the positions corresponding to the converging positions of the two diffracted lights, the lights of wavelength lambda1 and lambda2 entering simultaneously from the fiber 8 are separated according to the wavelength, so that they may be picked up from two optical fibers separately.
