Title: Method for analyzing misalignment between images
Inventor: TOKIDA RURIKO
IPC: G01B15/00
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To automatically eliminate an artifact by calculating the cross- correlation function between images, and by specifying the amount of misalignment between images from a position with the maximum cross- correlation function. SOLUTION: When the cross-correlation function of an image pair 1 is calculated if contrast due to the fluctuation of a gain is larger than that of a sample, a peak such as δ for a zero point, namely, the peak where the level is finite but the width is equal to one pixel, is generated. When the misalignment between images is analyzed by using the image where noise depending on a detector is included, a cross-correlation function 2 is calculated and the δpeak that is an artifact is eliminated from the calculation result of the crosscorrelation function 2. The generation position of the δ peak is fixed, thus substituting the strength of the position for the interpolation value of proximity data for eliminating the artifact.  After that, the maximum cross-correlation function is specified and the amount of misalignment is obtained, thus reducing erroneous recognition and applying to an image with a low image contrast.

Title: Holder for fitting protection pipe for optical cable to utility pole
Inventor: MAENO TAKEHIRO
IPC: H02G1/06
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To obtain the holder which is easy to use by forming a holder main body which is clamped to utility pole with a band body, from an elastic raw material and recessing a clamp groove that the protection pipe for an optical fiber engages in the front surface of the holder main body so that its diameter can be expanded.

When the clamp groove 3 is engaged with the protection pipe 2, the clamp groove 3 is increased in diameter because of the elasticity of its raw material since the protection pipe 2 has an external diameter larger than the diameter of the clamp groove 3 to engage the holder A and protection pipe 2 with each other, so that the holder A and protection pipe 2 are mutually assembled. The band body (b) is clamped to a utility pole D engaging the band body (b) with a cut formed in the opening end of the clamp groove 3 and then the protection pipe 2 is fitted to the utility pole D through the holder A.

Title: Device for treating foul water in skyscraper
Inventor: NAKANO ATSUO
IPC: C02F3/22
Filed: 1977-12-14
Abstract: PURPOSE: To efficiently regenerate and utilize foul water proudced in a skyscraper, by providing a long tubular aeration unit in the skyscraper over its height and aerating the foul water.  
     CONSTITUTION: An aeration pipe 3 is provided in the skyscraper 1 over its height. Oxygen gas or air etc. is blown into the aeration pipe 3 at its halfway height through a gas pipe 10'. The lower end of the aeration pipe 3 is located in an aeration liquid vessel 11. Therefore, the foul water transferred into the top of the aeration pipe 3 through an air lift pipe 8 is interrupted by rising bubbles while the water flows down in the pipe 3. At a result, the flowdown speed of the water is reduced and the time of contact between the liquid and the gas is lengthened, thereby obtaining a very high aeration efficiency. The liquid thoroughly aerated in the vessel 11 is removed of solids in a settling pond 4. The supernatant water undergoes a higher treatment and is then pumped up into a treated water vessel 6 to be re-utilized for lavatory etc.

Filed: 1988-06-17
Abstract: PURPOSE:To always obtain predetermined damping power even for a change of temperature of air by using a temperature sensing material of silicon rubber, bimetal, etc. for one or both movable and fixed cylinders. CONSTITUTION:A temperature sensing material W3 of silicon rubber, bimetal, etc. is used as the material for one or both movable cylinders 5a, 5b and fixed cylinders 6a, 6b. By using the temperature sensing material, the movable cylinders 5a, 5b and the fixed cylinders 6a, 6b are deformed so as to increase their volume, when a temperature increases, reversely so as to decrease the above volume when the temperature decreases. When the temperature of air increases, viscosity decreases, but a separating distance between cylinder groups 5a to 6b decreases, and damping power can be held to a fixed value. When the temperature of air decreases, the separating distance of the cylinder groups 5a to 6b reversely increases.

Title: System for generation of motion-corrected output picture
Inventor: MAACHIN RETSUKUSU DORIKOTSUTO
IPC: H04N11/04
Filed: 1994-06-30
Abstract: PURPOSE: To improve the quality of an output video image by controlling system parameters more efficiently. CONSTITUTION: An output interpolation video image is temporally almost in matching with an input video image on a current video signal line. Thus, a system output is extracted from a tap of an output of a multiplier 28. A motion vector between input video image temporally adjacent to each other is fed to vector application and interpolation units 24, 26. Let a time position (t) be nearly zero, then the unit 24 conducts zero motion compensation effectively and the unit 26 projects the motion vector in an opposite direction to the utmost to generate an interpolation video image corresponding to the system output. A weight coefficient +1 (-1) is fed to a multiplier 28 (30). As a result, an output from an adder 32 is equivalent to an error signal. If the interpolation is entirely correct without any artificial noise, the error signal at all points in an output video image is zero.  The error signal is filtered by an error filter and the result is fed to an adder unit, from which a control input to a system converter is given via a controller.

IPC: G11B19/02
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of a device by reducing an output drive current when an optical head is positioned at a scanning end of the home position side of an information recording medium after recording information or reproducing recorded information by scanning with an optical spot. SOLUTION: After completion of scanning, an MPU 205 discriminates whether an optical head 204 is positioned at a detectable scanning end by a position sensor 206. When it is positioned at the detectable scanning end, the current of a pulse motor 213 is cut off. However, the holding torque of the pulse motor 213 is small in this state, and the optical head 204 has a possibility of being moved by vibration and tilt during the stop. After that, the position of the optical head 204 is discriminated again by a scanning part instruction of the MPU 205. When it is positioned at a spot detectable by the position sensor 206, scanning is started. When it is not, the optical head 204 is moved and then scanning is started.  When scanning is performed, control pulses are counted using the low level of the position sensor 206 signal as reference, the current of the pulse motor 213 is controlled by ON and OFF, the scanning of the optical head 204 is performed, and the recording and reproduction of information are performed.

Title: Apparatus for keeping loaded chain or the like always in tensile state
Inventor: KOBAYASHI TOSHIAKI
IPC: F16G13/12
Filed: 1979-11-18
Abstract: PURPOSE: To keep a loaded chain always under tension, by providing a tension spring or a compression spring at a chain slackening section.  
     CONSTITUTION: A resilient member 1 is formed by a tension coil spring or a compression coil spring. A compression spring 1b is held in place by a retainer cap 5 and a frame 4, and one end portion of the resilient member 1 is fixed by a spring-end fixing member 3. Similarly, a chain is also fixed to the fixing member 3 by a conventional chain fixing means. Here, the slack length of the chain at a chain slackening section 2 is selected such that it does not exceeds the effective range of resiliency when tension spring 1a is expanded or compression spring 1b is contracted by a load. That is, in case of using a tension spring, the slack length is selected at a value smaller than the maximum length of expansion, whereas in case of a using a compression spring, it is selected at a value smaller than the length from the point where the end of the spring is located due to its natural expansion under loadless condition to the point where the spring is located when it is contracted maximally by the load. Since, with such an arrangement, the load is shifted to the slackening section with the spring being expanded maximally and without causing contraction of the same and then the load is supported together with the chain or only by the chain, it is enabled to keep the chain always under tension while balancing expansion and contraction of the spring.
