Title: Top blowing lance
Inventor: KATO YOSHIHIDE
IPC: C21C5/46
Filed: 1995-04-03
Abstract: PURPOSE: To restrain the development of splash and to reduce the development amount of dust, at the time of blowing onto iron bath surface from a top blowing lance. CONSTITUTION: A main spouting hole 3 is arranged at the tip part of the lance body 10 so that an extending line of the spouting axis for jetting gaseous oxygen collides against the surface of the molten iron. Auxiliary spouting holes 4 for jetting the gaseous oxygen, having θ=90 deg.±60 deg. angle axis to the spouting axis on the inner surface at the outlet part of the main spouting hole 3, are arranged. Since the oxygen jet jetting from the main spouting hole 3 is widened with the jetting gas from the auxiliary spouting holes 4, the gas flow velocity distribution is flattened as showing with the arrow marks. By this manner, the development of the splash is restrained and the development of the dust can be reduced.

Title: Tapping unit for turret punch press
Inventor: NODA YUICHIRO
IPC: B21D28/36
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain the tapping unit for turret punch, which can be inexpensively manufactured with a simple structure by making unnecessary an independent drive motor for revolving the tapping, a circuit, etc., detecting that a tap reaches a bottom dead center. SOLUTION: The front surface of an elevating/lowering part 20 is pressed by lowering the ram 43 of the turret punch press TPP. Since the spring constant of the elastic member 13 on the bottom surface of a housing 10 is smaller than an energizing member 21, the whole of a unit main body is lowered. A mounting part 11 projects from the bottom surface of the turret 40, and a work to be worked is pushed down on a lower die 43. Next, the elevating/lowering part 20 is further pressed by the ram 42, and is lowered in the housing 10. A rack 31 is simultaneously lowered in the housing 10 as well, a gear group 32 engaging with the rack 31 is revolved successively, and the spur gear 33 of a chuck 2 is revolved as well.  Consequently, the normal rotation of a bit 24 for tapping, mounted on the tip of the chuck 22, is performed while the bit 24 for tapping is lowered, and tapping is performed to the work.

Title: Burner
Inventor: ONO YUKIYOSHI
IPC: F23D14/78
Filed: 1985-04-12
Abstract: PURPOSE:To suppress temperature rise in the whole of a catalyst body and reduce its deterioration due to heat by providing a pre-mixture gas supply opening for fuel and air, a cooling gas supply opening for a catalyst body, and a combustion exhaust gas discharge opening and installing the cooling gas supply opening for the catalyst body substantially on the central axis of the catalyst body & opposite to the front face of the catalyst body. CONSTITUTION:A pre-mixture gas for combustion is sent from a pre-mixture gas supply opening 1 for fuel and air to a catalyst body 3. The pre-mixture gas makes catalystic combustion while it passes through the through-hole 4 of the catalyst body 3, and on the other hand a catalyst body cooling gas flows through the through-hole 4 near the center of the catalyst body 3 and absorbs the heat generated by the combustion of the fuel in the through-hole 4, and since the cooling gas mixes with the exhaust gas, the combustion heat does not stay in the catalyst body 3 but exits rapidly out of the system, reducing the temperature of the catalyst body 3 to 200-300 deg.C for the same volume and the same amount of combustion with the result of extending the life of the catalyst body 3 more than twice the ordinary life.

Title: Welding process for zinc-plated steel sheet
Inventor: UCHIHARA MASATO
IPC: B23K9/16
Filed: 1993-03-10
Abstract: PURPOSE:To change zinc vapor to a solid ZnO, and to suppress the generation of a blowhole by adding a large quantity of oxygen in shield gas. CONSTITUTION:In the gas shield metal arc welding of a zinc-plated steel sheet, a mixed gas contg. >10vol.% O2, and consisting of Ar and one kind or two kinds of CO2 as the remainder as shield gas, is used. A welding is performed by preferably using a pulse-like current. The oxygen in shield gas changes zinc vapor generated during welding to ZnO of a high boiling point, reduces a quantity of zinc vapor, stabilizes an arc, and suppresses the generation of spatters. A remarkable effect is attained with >20% oxygen content in shield gas. However, the shield gas with a high density of oxygen, causes frequent occurrence of spatters and a deterioration in bead shape. It is desirable to make it 60% or below.

Title: Mechanism for pulling connecting screw out inversely for use in thread fastener
Inventor: FUJIYAMA TAKEO
IPC: B23P19/06
Filed: 1994-03-24
Abstract: PURPOSE:To enable a connecting screw to be pulled out inversely by pressing and releasing a drive wheel from a feed wheel when a pressure rod is engaged with the second engagement portion of an operating block, thus undoing a one-way clutch mechanism. CONSTITUTION:A pressure rod 26 is disengaged from a first engagement portion 24 by the pressing in of the operating portion of an operating block 22, and is abutted and engaged with a second engagement portion 25 while being pushed back by the side of the operating block 22, so a drive wheel 10 is pressed against the force of a compression spring 17 and separated from a feed wheel 9. The engagement projection 16 of the drive wheel 10 is therefore disengaged from the engagement groove 15 of the feed wheel 9 and a nonreturn claw 18 is also separated from the outside face of the feed wheel 9 and unlocked from the engagement projection 21. Thus a one-way clutch mechanism is undone so that the feed wheel 9 can be inverted, Therefore, a connecting screw 7 can be easily pulled out inversely.

Title: Testing method for indentation hardness
Inventor: ABENO NOBUYUKI
IPC: G01N3/40
Filed: 1987-03-30
Abstract: PURPOSE:To accurately compare the hardness of a sample by finding the hardness of the sample from a measured test load and the preset depth of indentation. CONSTITUTION:A load increase speed is decreased at the point of time of depth D0 before the set indentation depth D1 is reached, and the load is so increased that the depth D1 of indentation is reaches in time t3=t2-t1, where t2 is the time when the depth D1 is reached and t1 is the time when the depth D0 is reached, thereby measuring the depth of indentation and the load when time t3 is elapsed. Then the depth D1, depth D0/D1, and time t3 are set and the test is conducted. Thus, the load is placed so that the depth of indentation to the sample is equalized and the hardness is compared by using the difference in the load, so the influence of a base board where the sample is mounted is equalized and the hardness comparison is accurately performed.

Abstract: PROBLEM TO BE SOLVED: To make the film thickness of an SOI layer in the wafer plane uniform, in the case of SOI substrate formation, and microminiaturize a semiconductor device formed on the SOI substrate. SOLUTION: The surface 11a of a silicon surbstrate 11 which surface is unevenly formd is covered with an insulator turning to a polishing stopper layer 12, and a polishing substrate 16 is joined. By chemical polishing using polishing solution composed of alkaline solution, the silicon substrate 11 is polished from the back side in such a state that the protrudirug parts of the silicon substrate 11 are left as an SOI layer 10. In this case, the polishing pressure and the number of revolution of a polishing pressure and the number of revolution of a polishing surface plate are so set that the differential coefficient of film reduction speed of the silicon substrate 11 becomes nearly equal to the differential coefficient of film reduction speed of the SOI layer 10, to the product of the polishing pressure and the number of revolution of the polishing surface plate.  Thereby the film reduction of the SOI layer 10 in the chemical polishing is restrained, and film thickness precision of the SOI layaer 10 is ensured.
