Title: Image pickup unit and device and method for detecting pixel defect in solid-state image pickup element
Inventor: NISHIWAKI KAZUHIKO
IPC: H04N5/372
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To easily and correctly detect the pixel position of a black defect in a solid-state image pickup element by storing the pixel position detected by a black defect detecting means, reading it to interpolate an image pickup signal obtained from the pixel position and detecting the pixel position on the basis of an image pickup signal which is obtained from a solid-state image pickup element when an image pickup light which is blurred by an optical means and has a uniform lightness is inputted. SOLUTION: In a digital camera device 1, a micro-controller 8 reads defect address information from a non-volatile memory 11 and supplies the information to the interpolating circuit of an image processing circuit 5. The interpolating circuit 21 creates pixel data obtained by interpolating a pixel value from circumferential pixel data concerning the pixel indicated on the defect address information, replaces it with original pixel data and supplies it to a digital clamp circuit. A digital camera device 1 easily and correctly detects the pixel address of a black defect in a CCD image sensor 3 and interpolates the detected black defect so that the image pickup element can be used even when a black defect is present.

Title: Detrack detector
Inventor: WACHI SHIGEAKI
IPC: G11B7/09
Filed: 1988-04-16
Abstract: PURPOSE:To detect a detrack with high accuracy by using a sub light spot away from a main light spot by a prescribed distance and detecting the detrack. CONSTITUTION:A sub light spot SS is formed away from a main light spot S for reading recorded information by a 1/4 track pitch Tp/4 in the radius direction of an optical disk 1 and detrack signal SDE whose phase is shifted by 90 deg. from a tracking error signal STE is obtained. The detrack is detected with 0[V] which is the center voltage of the detrack signal SDE as a reference. When an off-track quantity goes to the 1/4 track pitch Tp/4 even when the reflectance of the optical disk 1 changes, the detrack can be surely detected. Thus, a detrack detector whose detection accuracy is particularly high can be obtained.

Title: Porous electrode base board of ni-hydrogen battery
Inventor: TAKAHASHI SHOICHI
IPC: H01M4/32
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To enhance porosity, reduce a dead space, enhance strength, and use inexpensive iron instead of Ni by forming an electrode base board of nonwoven fabric of iron fiber on which Ni plating is performed, and pressurizing and sintering a crossing part of the iron fiber. SOLUTION: A porous electrode base board is formed of nonwoven fabric of iron fibers on which Ni plating is performed. A crossing part of the iron fibers is pressurized and sintered. The Ni plating of a surface of the iron fibers is economical after pressurization and sintering. The Ni plating may be either of electrolytic or electroless plating. A plating thickness requires 0.5 micron or more from the viewpoint of corrosion resistance. The diameter of the iron fibers is desirable to be 20 to 80 micron, and the length is desirable to be 20 to 100mm. It is desirable that the iron fibers are sintered in a range of about 900 to 1150 deg.C while pressurizing to about 0.5g/cm<2> in a reducing or nonoxidizing atmosphere. A component of the iron fiber can be properly selected up to low carbon steel from pure iron.

Filed: 1993-04-21
Abstract: PURPOSE:To obtain an excellent picture with less false color in a high frequency component of a luminance signal through simple circuit configuration by smoothing a picture element signal of each color and applying specific arithmetic operation to each smoothed color signal. CONSTITUTION:A light made incident from a lens 1 is spectrally dispersed into R, G, B signals by a 3-color separation prism 2 and the image is respectively formed on image pickup elements 3-5. The elements 3-5 mix signals of 2 picture elements adjacent in vertical directions to provide one signal output. Each signal is A/D-converted by A/D converters 6-8 and R', G', B' signals are obtained. After the R', G', B' signals are written in memories 9-11, they are smoothed by LPFs 12-14 and inputted to an arithmetic operation circuit 15, in which a ratio of an LPF output of a K-th picture element on a coordinate of a picture element of a J-th picture element to a J-th LPF output of the coordinate of the picture element is multiplied with the J-th picture element output signal to obtain a signal resulting from the assumption that a picture element of a K-th spectral sensitivity characteristic is in existence in the coordinate of the picture element. A color signal is calculated from signal.

Title: Wide range pressure control system
Inventor: NAKAYAMA SATORU
IPC: G05D16/00
Filed: 1990-04-09
Abstract: PURPOSE:To enlarge the range of pressure control by providing an exhaust line and a adjustable valve between a mass controller and a chamber in a pressure controller keep pressure in the chamber constant while controlling the flow of gas flowing into the chamber. CONSTITUTION:A valve 4 of a bypass line 3c is closed and pressure valve detected by the pressure gage 6 of a chamber 7 is defined as a feedback signal and compared with the set target pressure valve of a pressure controller 1. Then, feedback control is exerted onto a mass flow controller 2 and a adjustable valve 5 so as to reduce an error signal, and they are controlled so that the pressure of the chamber 7 can be fixed. When detecting the flow near or less than the minimum flow of the controller 2, this device 1 opens the valve 4 of the line 3c connected with an exhauster 8. Thus, the output flow of the controller 2 is branched and for the real flow into the chamber 7, the range is enlarged in the direction of flow smaller than the flow-in control range of the controller. Thus, the pressure control range is easily enlarged.

Abstract: PURPOSE:To combine a transmission control device precisely with a network and to reconstitute the network by starting an address searching means when a deciding means decides the passage of a prescribed time from the execution of the address searching means. CONSTITUTION:When the reception of a token is not the initial token reception after token disappearance due to the generation of an immeasurable accident, the token transfer operation is that executed every fixed period during which the token is circulated again to a certain node or that executed every fixed time period is checked, and at the passage of the fixed period, a node newly combined with the network is processed. If the fixed period has not yet passed, the token is transmitted by using the node address value stored in a memory circuit and used at the preceding token transfer as a destination address. Then, whether the token is normally transferred or not is checked, and when the transfer is normally executed, the succeeding data transmission is prepared again.
