Filed: 1989-06-29
Abstract: PURPOSE: To easily produce molten cast iron having a low content of sulfur, by adding granular desulfurizing agents into a plasma torch supply nozzle at the time of producing molten iron in a plasma combustion type cupola.  
     CONSTITUTION: The lower part of the cylindrical cupola 5 lined with refractory bricks 7 is provided with a nozzle 21 having a plasma torch 23. Lump coke, scrap pig iron, scrap steel, and a flux, such as dolomite, are charged from a raw material charging section having an opening 13 into the cupola and the coke is ignited by the plasma torch 23. Air is blown by a pipe 37 into the cupola to burn the coke. The charged materials are melted by the heat of the combustion to form the molten pig iron and molten slag. Exhaust gases are partly returned via a cyclone separator 33 and a pump 35 to the cupola 5. At this time, the granular desulfurizing agents, such as CaO, MgO, CaCO 3 , MgCO 3  and CaMgCO 3  (dolomite), are supplied from a bin 25 into the nozzle 21 for the plasma torch. The molten iron is subjected to a desulfurization treatment by the desulfurizing agents described above and is taken as the cast iron out of the cupola. The molten iron is also a raw material for spheroidal graphite cast iron by Mg. Since just the slight energy for desulfurization is necessitated, the erosion of the refractory bricks 7 due to a high temp. is lessened.

Filed: 1993-06-16
Abstract: PURPOSE:To reduce a rush current at the time of starting a heater by providing a prescribed time difference to a time of starting energizing plural heaters in the case that the detected temperature is lower than a prescribed reference temperature. CONSTITUTION:The heater is installed on both, or either of heat rollers which are in press-contact with each other, and when the temperature of the heat roller detected by a thermistor does not reach a temperature permissible to simultaneously turn on the heaters, the timing of turning on/off a previously decided signal is judged. When a timing of turning on, for example, the heater S3, that is, the timing of turning on a signal S3 is obtained, the signal S3 is turned on, and a signal S5 is turned off. When a timing of turning on the signal S3 is not obtained, the signal S3 is turned off, and the signal S5 is turned on. Thus, two heaters are not simultaneously energized, so that the absolute value of the current flowing in the heater becomes smaller than the conventional one, then, the influence on other equipments, for example, flickering of a fluorescent lamp, etc., in a room is reduced.

SOLUTION: A semiconductor chip is cut and the sections of the chips are polished to make the P-N junction part to be measured between the chips expose (SET-1). Then, a wiring, which is connected with the exposed P-N junction part to be measured, is cut (SET-2). In concrete terms, a hole is bored in the part, which is located at the P-N junction part to be measured, of the wiring for cutting physically the part, which is located at the P-N junction part, of the wiring using a focusing ion beam unit or the like. Then, the P-N junction part is actualized with an etching liquid (SET-3). The actualized P-N junction part is observed by a high-resolution electron microscope and the depth and length of the P-N junction part, the interval between the P-N junction and the like can be measured (SET-4). Moreover, it is also possible to short-circuit the P-N junction part with the other junction part in place of cutting the part, which is located at the P-N junction part, of the wiring (SET-2). Thereby, the effect of the periphery of the P-N junction part is prevented and a measurement of a semiconductor device can be stabilized.

IPC: C03B37/014
Filed: 1990-06-27
Abstract: PURPOSE:To prolong a life of furnace by heating an optical fiber preform to be put in a furnace core tube by a heater arranged in the circumference of the tube, feeding a dehydrating agent-containing gas to the preform and continuously applying a torsional moment to the furnace core tube. CONSTITUTION:An optical fiber preform 6 is put in a furnace core tube 2 arranged at the central part of main body 1 of a dehydrating and sintering furnace, a dehydrating agent and a He gas are fed from a He gas feed opening 21 to the furnace core tube 2 in a heated state by a heater 3 and the preform is dehydrated and made into transparent glass. The viscosity of the heated part of the furnace core tube 2 is reduced by heating by the heater 3 and the heated part tends to swell outside by difference in pressure between pressure in the interior of the furnace core tube and the main body 1 of the furnace. Since force in the revolving direction is always applied to a plate 71 by a torsion providing device 7 attached to the lower part of the furnace core tube 2 and inward force acts, the furnace core tube 2 is prevented from swelling outside and life of the furnace core tube 2 can be prolonged.
