Title: Guide for pulling in inner pipe
Inventor: KATSUKI HARUHIKO
IPC: E21D9/06
Filed: 1994-04-19
Abstract: PURPOSE:To prevent the increase in the frictional resistance and the rolling phenomenon in a propulsive steel pipe when a bundle of inner pipes is pulled in. CONSTITUTION:A rotary tool 5 to reduce the frictional resistance with the inner wall of a propulsive steel pipe is arranged on the circumferential surface side of a body 4 whose diameter is slightly smaller than the diameter of a protective pipe (the propulsive pipe 3), and a rope 7 for fraction is connected to the center of the forward flat surface part of the body through a forward body 8 of revolution. A guide rope 13 is connected to the center of the rear flat surface part of the body 4 through a rear body 11 of revolution. The deviation of the tracting direction from the pipe axis of the advancing steel pipe is reduced. This constitution prevents the uneven tracting force from being applied to the bundle 2 of inner pipes, and prevents the increase in the frictional resistance and the rolling phenomenon in pulling in the bundle 2 of the inner pipes.

Filed: 1990-03-30
Abstract: PURPOSE:To discriminate the propriety of a state of a tape in use by adding a flag by which whether or not number of errors corrected by at least one parity in a parity group is communicated is discriminated to an operating command received from a host computer. CONSTITUTION:A flag deciding whether or not a BER is sent is added to a command sent from a host computer to transmit the BER to the host computer.

Abstract: PURPOSE:To remove phosphorus contained in waste water by a biological treatment efficiently by treating overflow water from an excess sludge concentration tank and/or P-contg. org. waste water from a sludge dehydration stage further with a physicochemical dephosphorization means. CONSTITUTION:Suspended solid in the feed water is removed in the first stage in a settling basin 1, then fed to a aeration tank 2 where it is mixed and allowed to contact with returned sludge. The activated sludge adsorbs org. substances in the fed water and liberates phosphorus compds. The liquid mixture is transferred to an aerobic tank 3 where oxidation of the org. substances and accumulation of phosphorus compds. in the activated sludge are taken place. The solid and liquid in the sludge accumulating a large amt. of phosphorus compds. are separated in a final settling basin 4; a part of the separated solid is transferred to an anaerobic tank 2 as returned sludge and the rest is transferred to a sludge concentrating tank 5 as excess sludge. The overflow water from the concentration tank and the waste water from a dehydrator 6 are treated in an adjusting tank 7 to adjust their pH, then dephosphorized in a physicochemical dephosphorization tank 10, and returned to the initial settling basin 1.

Title: Side of traffic lane recognizing device
Inventor: MAEMURA TAKAHIRO
IPC: G01B11/00
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To keep high the recognition accuracy of the side of traffic lane by estimating and interpolating the position of the side of the traffic lane end based on a moving amount when a vehicle turns and a traffic lane yaw angle gets larger than a prescribed value. SOLUTION: While the vehicle is traveled, a CCD camera 2 is operated, image pickup information is inputted to an ECU 10 and image processing is performed. Based on this image processing information, the ECU 10 calculates the angle of the longitudinal central line of the vehicle to a traffic lane, namely, to a white line, namely, the lane yaw angle (traffic lane yaw angle). Then, by performing the threshold value discrimination of the lane yaw angle, it is mainly discriminated whether the vehicle just changes a traffic lane or just travels on a curve along the traffic lane. When the vehicle just changes the traffic lane, the estimating and interpolating processing of white line recognition is executed at an interpolation part 16. Then, at a moving amount calculation part 17 inside the interpolation part 16, the moving amount of the present vehicle is calculated and based on these fine longitudinal moving amount, fine lateral moving amount and fine yaw angle, coordinate transformation is performed.
