Abstract: PURPOSE:To efficiently smelt a stainless steel without using expensive reducing agent by using a top-bottom combined blowing converter, reducing chromium oxide content in decarburized slag produced in the previous heat with the charged molten iron and executing decarburization-refining in the same furnace after removing the slag. CONSTITUTION:In the condition of leaving the slag 1 produced with the decarburizing in the previous heat, the molten iron I2 executing dephosphorizing and desulfurizing treatments and containing no chromium is charged into a converter, and oxygen-blowing and temp.-raising are executed while adding excess carbonaceous material having 10-60% of the slag wt. to reduce the chromium oxide in the slag. Successively, the furnace is tilted and a part or a large part of slag is removed and again, the molten iron II 3 executing dephosphorizing and desulfurizing treatments and containing no chromium is charged. Thereafter, the furnace is returned back to the original posture, and the oxygen-blowing is executed while adding ferro-chromium and flux to execute the decarburization-refining. At this time, the wt. ratio of molten iron I/(molten iron I + molten iron II) is made to be 45-75%. After lowering to the aimed carbon concn., again the furnace is tilted to tap only the molten steel and the slag 5 containing the chromium oxide is left in the furnace and the dephosphorized and desulfurized molten iron in the following heat is received.

Filed: 1985-01-17
Abstract: PURPOSE:To constitute a titled pen so that learning can be executed at an appropriate writing pressure informing an operator that a necessary writing pressure is applied to a pin, when an operator is operating a pen, and the pen is in a state that its input can be executed. CONSTITUTION:In case of writing a segment M to a tablet paper surface 7, write is started by making a pin tip 5 contact to the paper surface 7. In such a case, a core 3 moves in the direction as indicated with an arrow (a) by a writing pressure, and a pressure sensitive switch 4 goes to an on-state. As a result, a current flows to an LED6, and the LED6 is turned on. An operator can confirm a fact that an input is executed by a correct writing pressure, by turn-on of this LED6. On the other hand, when the writing pressure is weak and the core 3 does not move in the direction as indicated with an arrow (a), the pressure sensitive switch 4 remains an off-state, therefore, the LED6 is not turned on. Accordingly, the operator can decide immediately a fact that the present writing pressure is weak and it is not recognized correctly, by confirming this LED6.

IPC: H01L21/18
Filed: 1979-01-18
Abstract: PURPOSE: To enhance the yield of silicon single crystal production by a pulling method using a quartz crucible by applying a rotating magnetic field to the crucible from the outside to control the oxygen content of single crystal silicon.  
     CONSTITUTION: In production of a silicon single crystal by the Czochralski method, by varying the direction and intensity of a rotating magnetic field from the outside of a crucible with a heater using three-phase AC, convection of molten silicon in the crucible and flowing of the melt surface are controlled. Penetration of O 2  into the molten silicon due to slow dissolution of quartz from the quartz crucible surface is inhibited by controlling the degree of evaporation as SiO 2  on the melt surface to control the amt. of O 2  contained in a pulled crystal to 15W20 atomic ppm. Thus, single crystal silicon of superior properties is produced in a high yield.

Filed: 1990-01-12
Abstract: PURPOSE:To improve the addition yield of Al for alloying by adding and immersing Al into the position under the surface of a molten steel after subjected to decarburizing refining by means of oxygen blowing, carrying out reducing refining while maintaining a low vacuum, and also diffusing Al into the molten steel. CONSTITUTION:A molten stainless steel is subjected to decarburizing refining by means of oxygen blowing under reduced pressure in a VOD furnace. Metallic Al, reducing agent, and slagging agent are added and immersed under ordinary pressure into the position under the surface of the molten steel after decarburization. Reducing refining is carried out while maintaining the pressure at a low vacuum of >=40Torr for a sufficient time and also Al is diffused into the molten steel. The added Al functions as a reducing agent for chromium oxide and also an alloying material for producing a high Al stainless steel. By this method, the evaporation and volatilization of metallic Al at the time of refining can be prevented, and the component regulation of Al content in a product can be facilitated.

Title: Mounting structure of outside molding
Inventor: UI KATSUMI
IPC: F16B11/00
Filed: 1983-01-17
Abstract: PURPOSE:To surely secure an outside molding to the outside plate of a vehicle body, by providing thin-wall projections n both side of an adhesive receiving groove to inhibit a hadening type adhesive from flowing out. CONSTITUTION:Hardening type adhesive is beforehand coated in a groove 14 in an outside molding 10 which is attached with pressure-sensitive adhesive tapes 12 at its side surface and which is then pressed against the outside plate of a vehicle body. In this stage, the tapes 12 are subjected to pressing force by the reaction of the outside plate so that the molding 10 is temporally secured to the outside pate, and serve to retain the molding on the outside plate until the adhesive hardens. Although the adhesive deforms and flows, the adhesive is inhibited, by projections 16, from flowing toward the tapes 12, and therefore, the adhesive is only allowed to flow in the longitudinal direction of the molding 10. These projections 16 are deformed and held between the molding 10 and the outside plate to serve as a spacer for ensuring a space into which the adhesive is filled.

Filed: 1982-01-20
Abstract: PURPOSE:To hold a load voltage constant by using a DC voltage obtained by rectifying a commercial power source voltage for driving and controlling an ignition phase angle according to the value of an AC voltage applied to a load. CONSTITUTION:After power-up operation, a triac 23 does not turn on and while a load voltage is 0 and the gate voltage of a PUT10 is 0, but the DC voltage is applied through a full-wave rectifier 5 and resistances 6 and 8 to turn on the PUT10; and the termial voltage across a resistance drives a pulse transformer 11 and a triac 21 turns on. Then, the voltage across a resistance 22 turns on the triac 23 to apply the power voltage to the load 24. At the same time, a rectifier 19 starts rectification and while the voltage of a capacitor 17 rises gradually, the gate voltage of the PUT10 also rises; and the ignition angle of the triac 21 varies gradually and when the potential of the capacitor 17 becomes constant, the ignition angle of the triac 21 also becomes constant. Thus, the ignition angle varies with the power voltage and load to hold an output voltage constant.
