Title: Coating of existing pipe-line
Inventor: MIZUNO ISAO
IPC: B05C11/10
Filed: 1988-01-07
Abstract: PURPOSE:To improve workability of coating work of pipe-line by dividing a pipe-line into blocks at each branching point of branch pipes, and executing coating for each block. CONSTITUTION:Each predetermined amt. of coating material is charged to each coating material tank 10a, 10b, etc., connected to each branch pipe of a pipe-line to be coated. For executing, in the first stage, a coating work of a block A, a motor-operated valve 9a of the coating material tank 10a connected to an end of a branch pipe 4a at a starting side is opened by the operation of a controlling part 11. At the same time, air is blown into the coating material tank 10a through an air-hose 13 via a whirl stream generating device 12a by opening a valve 14a of a header 16a in an air distributing device 15. Thus, the paint is extruded under whirling state into the branch pipe 4a and a lateral pipe-line 3 and the inside of the pipe-line is coated. By this method, generation of uneven coating is prevented.

Title: Manufacture of conduit for control cable
Inventor: YOSHIOKA SHUNICHI
IPC: B32B1/08
Filed: 1989-01-06
Abstract: PURPOSE:To obtain excellent durability by a method wherein a layer made of highly orientated polymer material, which is produced by stretching crystallizable polymeric compound by induction heating, is provided on a conduit. CONSTITUTION:Either one or both of a coil spring layer 1 or a shielding wire layer 4 or at least one between a supporting layer 6 and a reinforcing layer 7 is obtained by selectively heating and stretching the non-crystalline portion of crystallizable polymeric compound by induction heating. The obtained highly orientated polymer has the mechanical strength in width direction, which is equal to that of carbon steel, as the result that the orientating property of the non-crystalline portion is remarkably improved under the condition that the mechanical strength of the crystalline portion is kept unchanged, and at the same time is excellent also in flexibility, dimensional stability and compression strength. Further, since the degree of crystallization of the obtained highly orientated polymer becomes higher, its heat resistance is enhanced. As the crystallizable polymeric compound, any thermoplastic derivative will do and polyether, polyester, vinyl polymer and the like are exampled.

Title: Magnetic head
Inventor: UCHIBORI NAOKI
IPC: G11B21/20
Filed: 1985-01-09
Abstract: PURPOSE:To control easily the coating amount of resin when a slider assembly is attached to prevent a fault due to the swell-out of resin and to secure the satisfactory adhesion intensity, by providing the hole for injection of the adhesive resin to a gimbal or a plate to which the slider assembly is attached. CONSTITUTION:To holes 6 for injection of the adhesive resin are formed to a gimbal or a plate 1 for attachment of a slider assembly 8 for a miniature floppy disk magnetic head, etc. At the same time, a level difference l is secured to a slider 5 to a slider 4. Then the adhesive resin is injected only to a gap between the slider 5 and the plate 1. Thus the amount of the adhesive resin swelling out of the assembly 8 is limited by the hole 6. Then the swell-out amount of the resin is minimized together with the satisfactory adhesion intensity secured. This avoids such as case where a shielding plate floats over the plate 1 when the shielding plate is adhered to the assembly 8 and touches a magnetic disk.

Title: Quartz glass crucible for pulling up silicon single crystal and its production
Inventor: KITANO KOZO
IPC: C30B15/10
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To produce a quartz glass crucible capable of improving the yield of a pulled-up silicon single crystal by forming a specific amount of oxygen-lacking defects in a layer at a specified distance from the inner surface of the crucible. SOLUTION: An oxygen-lacking defect part of 20-150 ppm is formed in a layer within 1 mm from an inner surface of a crucible. A carbon mold 12 is charged with a quartz powder 11 so as to form a crucible shape by rotating a crucible-forming mold 10 by a motor 17. The crucible-forming mold 10 charged with the quartz is transferred to a melting room 5. An inert gas (e.g. nitrogen) is flowed from a flowing-in opening 6 to the melting room 5 to replace the atmosphere so that the oxygen concentration of the atmosphere of the melting room 5 may be <=21% (e.g. <=1%). The quartz powder 11 is serially melted by charging an arc electrode 15 with electricity. A vacuum pump 20 is operated just after the start of the arc discharge, and a reduced pressure state is kept for a prescribed time (e.g. 10 min). A reducing gas (e.g. hydrogen) is flowed into the melting room at a 50-300 L/min from the time just before the start of the arc discharge for 5-15 min. Thereafter, the flowing in of the hydrogen is stopped and the arc discharge is maintained for a prescribed time (e.g. 30 min) to provide the objective crucible.

Abstract: PURPOSE:To improve working properties, by a method wherein, after concrete is placed in an excavated hole, a low-strength curing layer is formed in a region above a designed pile head, and after concrete is set, the low-strength set layer is removed together with a ground therearound. CONSTITUTION:After concrete 2 is deposited in an excavated hole 1, an implanting pipe 11 is inserted into an extra-banking part 4 before the concrete is set. A setting agent solution for a ground is injected into an area consisting of a stabilizer 12 and a non-good quality of concrete 13, positioned above a planning pile head 5, through the injection pipe 11 to form a low-strength set layer 14 of non-concrete material. After the concrete 2 is set, the low-strength set layer 14 is removed togetherwith a ground material 3 therearound by an excavating means to complete a disposition of pile-heads. This permits the reduction in the number of working stages through elimination of a refilling work.
