Title: Liquefaction ground improving method
Inventor: SAKO SHINICHI
IPC: E02D3/12
Filed: 1990-10-26
Abstract: PURPOSE:To easily and effectively prevent the liquefaction of the ground by laying a layer for draining the pore water raised from the ground to the earth's surface after forming a mesh-like or grid-like impervious wall while pouring solidification material in a liquefaction ground. CONSTITUTION:A solidification material pouring pipe insertion hole 2 is excavated in a liquefaction ground A by means of a boring device 1. In the next step, a solidification material pouring pipe 4 provided with a high pressure jet nozzle 3 on the head is inserted into the pipe 2. In the next, solidification material having high solidification strength, which is made by a solidification supply device 5 is forcedly sent into the pouring pipe 4 through a supply pipe 6 by a high pressure pump 7. In addition, an impervious wall element B is formed by gradually pulling up the pouring pipe 4 while jetting solidification material from the high pressure jet nozzle 3 at high pressure. The element B should be formed so as to be connected to each other every a given space apart by repeating this process. At last, the earth's surface is graveled forming a drain layer C of a given thickness. This constitution can effectively prevent the liquefaction of the ground and can restrain the shear deformation of the ground in earthquake.

Title: Double-pipe excavation bit and discharge control method thereof
Inventor: ENDO TETSUYA
IPC: E21B10/18
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To improve excavation performance by communicating the groove of the exterior wall surface of an outer bit with the groove of a front end face and inclining the groove of the exterior wall surface in the direction of rotation of the bit towards an upper section from a front end. SOLUTION: Radial front end grooves 6 tilted in the direction of rotation of the bit are formed at the front end of the outer bit 4, and communicated with outer circumferential grooves 7 formed to an external surface and inclined in the direction of rotation of the bit towards an upper section. When an excavation fluid is discharged from the front end of the central flow path of an inner rod at the time of excavation, slime generated on the outside of the bit 4 is introduced and discharged into an annular flow path between the inner rod and an outer rod from the grooves 7, 6 together with the excavation fluid. When the excavation fluid is drawn off from the front end of the annular flow path, slime on the outside of the bit 4 is introduced similarly to the inside of the front end, and elevated in the central flow path of the inner rod and discharged.  Accordingly, a rod detention accident, etc., can be prevented because no slime is left, and a cutting trouble such as a lost circulation due to the outer creeping of the excavation fluid can be obviated, and cement, etc., can be filled efficiently because no hole collapse is generated.

Title: Manufacture of superconducting cable in-conduit
Inventor: INOUE ITARU
IPC: H01B13/00
Filed: 1993-10-21
Abstract: PURPOSE:To manufacture efficiently a superconducting cable in-conduit having excellent quality and performance. CONSTITUTION:In a manufacturing method of a superconducting cable in-conduit where superconducting stranded wires are housed in a long size metallic pipe, the superconducting cable in-conduit is manufactured in a process to weld the mutual end surfaces of short size metallic pipes together by butting theme each other after at least superconducting stranded wires or element stranded wires formable as the superconducting stranded wires are loosely fitted in the plural short size metallic pipes and a process to perform compression molding on the butt-welded short size metallic pipes. Thereby, since the metallic pipes are formed in the short size, tensile force is not applied to the superconducting stranded wires when being loosely fitted in the metallic pipes, quality and performance become excellent, and since welding lengths of the metallic pipes are short, repair of welding failure is hardly caused, and reliability of airtightness becomes high.

IPC: B23K26/00
Filed: 1993-11-17
Abstract: PURPOSE:To reduce the calibrating time of a height sensor f a laser beam machine, and prevent the generation of failures such as the deformation of a nozzle. CONSTITUTION:A nozzle 1 is rapidly lowered to the prescribed position P1. and slowly lowered from P1 to the calibrating point P2.

When the contact signal of the nozzle with the calibrating point P2 is detected in the set time of the timer, the nozzle is elevated at each specified distance, the output of the height sensor is measured to execute the calibration. When the contact signal exceeds the set time, and the number is within the set value of a re-try counter 15, the nozzle is elevated above P1. The X-and Y-positions of the nozzle are slightly moved, and this operation is repeated. When the number of the re-try exceeds the set value of the re-try counter 15, the calibration of the height sensor is stopped.

Title: Method for diagnosing deterioration of steel pipe pole
Inventor: TAKEKOSHI RYOJI
IPC: G01N29/22
Filed: 1991-11-05
Abstract: PURPOSE:To perform the simple diagnosis for the states of corrosion and the like of the part of a steel pipe pole in contact with soil, which can be measured only after the removal in a conventional method, at the part on the ground in the using state. CONSTITUTION:An ultrasonic probe 1 and a rubber balloon 2 are inserted into a steel pipe pole 3 through a pole-step fixing hole 8 of the steel pipe pole 3. The balloon 2 is expanded with a pump 4. Thus, the ultrasonic probe 1 is brought into contact with the inner surface side of the steel pipe pole 3. The probe 1 is driven, and ultrasonic waves are imparted to the steel plate part and the like of the steel pipe pole 3. The multiple-reflected ultrasonic waves reflected from the outer surface side and the inner surface side of the steel pipe pole 3 are received with the ultrasonic probe 1. The periodicity of the multiple reflected ultrasonic waves and the like are operated in an operating part 6. The amount of corrosion, which is otherwise obtained beforehand, is compared with the ultrasonic wave data obtained by the receiving. Thus, the reduced thickness and the deteriorated state of the outer surface side of the steel pipe pole 3 are obtained. The corrosion of the underground part of the pole is determined without digging up the steel pipe pole 3. The poor workability is improved by the simple method such as this.

Abstract: PURPOSE:To prevent abnormal corrosion of a negative plate or a post by forming the negative plate and the connecting part of the negative plate and the post with an alloy containing specified materials. CONSTITUTION:A positive plate is formed with a grid comprising a lead- antimony base alloy. A negative plate is formed with a grid made of a lead- calcium base alloy containing 0.1-1.0wt.% tin, and the connecting part of the negative plate and a post is formed with a lead-antimony base alloy containing 0.15wt.% or less arsenic. Abnormal corrosion in the negative plate or the post is retarded and short life caused by separation of the plate is prevented. Since calcium is not used as additional lead, assembling man-hour is reduced.
