Title: Pipe cleaning device
Inventor: ENDO MITSUO
IPC: B08B9/04
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To make it possible to develop nozzle bodies and to inject high- pressure fluid from near the inside wall surface of a pipe at the time of shell removal work by providing the device with the nozzle bodies and guide bodies which are developed or folded by the force of the high-pressure fluid and springs and wheels in contact with the inside wall of the pipe. SOLUTION: When the high-pressure fluid is introduced into a cylinder via the hose 9-1, pistons 34 extrude output shafts 32 by overcoming the energizing force of the springs 33 and turn rods 31 to bring, the wheels 30 of the guide bodies 8 into contact with the inside wall of the pipe 2. The nozzle bodies 7 are similarly turned as well. When the shell removal of the inside wall of the pipe 2 is needed, the nozzle bodies 7 and the guide bodies 8 are placed along the main body 6 and the pipe cleaning device is passed into the flowing water from an opening while a cable and the high-pressure hose are held attached to the device. When the device descends down to the desired position, the high-pressure fluid is supplied to develop the nozzle bodies 7 and the guide bodies 8, thus bringing the wheels 30 into contact with the inside wall of the pipe 30.  The high-pressure fluid is spouted from the nozzles 24 and is blown to the inside wall of the pipe 2.

Title: Method for building brick of blast furnace wall
IPC: C21B7/06
Filed: 1989-12-25
Abstract: PURPOSE:To accelerate the adhesion of the bricks and joint mortar and to shorten the time for building by using the bricks formed by sticking org. matter to the surface of moldings and firing the moldings to increase the porosity of the surface. CONSTITUTION:The bricks formed by sticking the org. matter, such as phenol resin, pitch or tar, on the surface of the silicon carbide-base moldings and firing the moldings are used in building the blast furnace bricks. The porosity of the bricks surface is increased by the decomposition of the org. matter in the firing process of the moldings and the reaction to form SiO2 at the firing is suppressed. The joint mortar is interposed on the joint surfaces of the resulted silicon carbide-based bricks and the bricks are stacked vertically. The densification of the bricks surfaces is prevented in this way and the adhesion of the joint mortar is accelerated and, therefore, the continuous building of the bricks is possible.

IPC: G11B7/24073
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To reduce crosstalk between the adjacent tracks of header information formed in a header area by a prepit in the optical disk medium of a land and groove system.

Title: Water/hot water supplying hose
Inventor: SHIMOMURA KAZUHIRO
IPC: F16L11/10
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent kinking of a hose while keeping its flexibility by arranging a woven reinforcing layer made of monofilament on an outer side of an inner layer tube. SOLUTION: In a hose 3, an inner layer tube 1 is surrounded by a woven reinforcing layer 2 made of monofilament fiber. An innermost layer 1 of the inner layer tube l is made of material having resistance against chlorine water. Flexibility of the hose is not deteriorated by arranging the woven reinforcing layer 2 of the monofilament on an outer side of the inner layer tube 1. Kinking of the hose is prevented because woven monofilaments restrict each other for keeping the shape of the hose, even in a radius of bending where the conventional hose causes kinking or less. The monofilament fiber composing the reinforcing layer may preferably be 300 to 1000 denir. Its sectional shape may preferably be flat shape, such as an oval, long circular and chamfered rectangular shape.

Title: Optical semiconductor assembly
Inventor: ASANO SABUROU
IPC: G02B6/32
Filed: 1987-12-25
Abstract: PURPOSE:To maintain a high optical coupling efficiency stably for a long period of time by securing the section having relatively low thermal conductivity of a chip carrier to a lens holder by laser welding. CONSTITUTION:A chip carrier 11 is formed by integrally brazing a heat sink 12 to a lens holder supporter 13, and the supporter 13 is formed with a lens holder mounting hole 13a in a rectangular parallelepiped block made of a material having relatively low thermal conductivity. A lens holder 14 is formed of the same material as that of the supporter 13 of a lens holder 1. When the carrier 11 is secured to the holder 14, the holder 14 is slid longitudinally in the hole 13a, and the sliding end A is laser-welded at a suitable position. In this case, since the thermal conductivities of the supporter 13 and the holder 14 are low, the laser radiated part is locally melted and solidified, thereby forming a welded part which is not deformed in an ageing manner.
