Abstract: PURPOSE:To approach composition of molten steel at the time of stopping blowing to the target value with good accuracy by actually measuring quantity and composition of remaining molten slag in a converter of the previous heat and setting O2 quantity, gas for stirring and charging quantity of sub-raw material at the time of producing the molten steel by executing decarbonizing-refining in a top and bottom combined blowing converter to molten iron with pre-refining completed as raw material. CONSTITUTION:By using the molten iron with the pre-treating refining of desiliconization, dephosphorization, desulfurization executed, etc., as the main raw material, the molten steel is produced by decarbonizing with oxygen-blowing in the converter providing the oxygen top blowing lance and the bottom blowing nozzle for stirring bath. In this case, the quantity of the remaining molten slag in the converter of the previous heat is measured and also the contents of P, Mn, etc., in the molten slag are actually measured and O2 quantity for decarbonizing - refining with the oxygen-blowing, gas quantity for stirring from the bottom blowing nozzle, quantities of sub-raw materials of slag-making agent, ferro-alloys, etc., are set from contents of C, Si, P, S, Mn, etc., in the molten iron to start the O2 blowing. The composition and temp. of the molten steel during refining are measured, and based on these, by correcting the O2 quantity, stirring gas quantity and adding quantity of the sub-raw materials, the composition of the molten steel at the time of stopping the blowing can be approached to the target values with high accuracy.

Title: Manufacture of semiconductor device
Inventor: HIRAO TADASHI
IPC: H01L29/73
Filed: 1985-06-28
Abstract: PURPOSE:To improve the frequency characteristics of a semiconductor device only by providing an insulating film between a silicon film on an emitter region and a metal electrode film on a base region, thereby effectively reducing the interval between the emitter and the base, and reducing the resistance of the base. CONSTITUTION:In order to prevent a short circuit between a base electrode and an emitter layer 7, a nitride film 203 is deposited on the entire surface. The nitride film 203 is made to remain only on the side wall of a polysilicon film 603 by anisotropic etching. Then, an oxide film 108 is removed by using an RIE method again. The oxide film and the nitride film are made to remain on the side wall of the polysilicon film 603. Thus, the interval between the emitter and the base becomes approximately equal to the thickness of the oxide film 107 and the nitride film 203 on the side wall of the polysilicon film 603. Therefore, the resistance of the base becomes very low.

IPC: B41K1/00
Filed: 1984-07-11
Abstract: PURPOSE:To engrave a large number of seals and other sealing materials precisely at a time by replacing the movement of a profiling section, to which a detector profiling a sample on a master plate is mounted, with an electric signal and driving and controlling a driving table to which the sealing material is set.

IPC: B65H69/00
Filed: 1991-05-20
Abstract: PURPOSE:To obtain a loading table for a sliver joining robot excellent in operation rate by storing pipes extended along the traveling route of an overhead traveling carrier and connected to power supplies for compressed air and suction air in the loading table. CONSTITUTION:When a can for a spindle in a spinning device S nears empty, a can exchange signal is output from a constant length counter S' to a robot R suspended from an overhead traveling carrier SR waiting at a home position, and the overhead traveling carrier SR travels to a spindle where a can must be replaced and the robot R lowers. Then the lower part 12 of the robot only moves forward horizontally and binds a sliver by means of two chucks 35 and 36. When the lower chuck 36 is rotated downward, the sliver is cut off at a vertical position and an optical signal indicating completion of sliver cutting is sent to a can exchange control panel 6. Thus a vacant can C' is transported to a vacant can station 1 by a trolley T and a loaded can C is transported from a loaded can station 2, and the can is pressed onto the spindle where the can must be replaced and a sliver joining operation is started.

Title: Separator for lead storage battery
Inventor: YAMAZAKI KENICHIROU
IPC: H01M2/16
Filed: 1983-08-05
Abstract: PURPOSE:To reduce the cost of a separator for a lead storage battery while maintaining its liquid-absorbing property and tensile strength by using mixture consisting of not more than a specified amount of glass fiber, fibrilar synthetic fiber, monofilamentous fiber and inorganic powder to form the separator. CONSTITUTION:A separator for a lead storage battery is formed by mixture consisting of not more than 15wt% glass fiber, 10-30wt% fibrilar synthetic fiber, 10-40wt% monofilamentous fiber and 30-70wt% inorganic powder. The glass fiber has a mean fiber diameter of 1.0mum or below. The fibrilar synthetic fiber has a freeness of 5sec/g or greater. The monofilamentous fiber has a fiber diameter of 10mum or below. As a result, the hydrophilic inorganic powder prevents any reduction in the liquid-absorbing property which might be caused by increasing the amount of the synthetic fiber. In addition, the tensile strength is maintained by the fibrilar synthetic fiber having the restricted freeness. Thus, the cost of the separator can be reduced by decreasing the amount of the expensive glass fiber.

In addition, data I/O between the circuits 1 to 4 and the register 5 is executed by an event signal outputted from the multiplexer 9. Consequently, data transfer to/from the peripheral apparatuses can be executed independently of the function of a processor.
