IPC: C09C1/50
Filed: 1981-07-24
Abstract: PURPOSE:To remove impurities most efficiently from carbon black produced by thermal decomposition of liquid hydrocarbon in a high temp. gas stream, by passing it, carried by flowing gas, through a screen classifier. CONSTITUTION:Raw material liquid hydrocarbon fed into a furnace 11 from an inlet 12 is thermally decomposed with high temp. gas introduced from an inlet 13. The produced carbon black is quenched with a cooling medium supplied from an inlet 14 and carried on a gas stream through a heat exchanger 15 to a bag filter 16. Then the carbon black in the filter is fed by means of a rotary feeder 17 into a screen classifier, carried by high temp. gas stream fed from the heat exchanger 15 and a combustion gas generator 30 and, after removal of impurities in small lumps such as refractory material in fragments, rust from equipment and coke, final product carbon black is taken out via a collector 22.

Title: Dc power supply unit
Inventor: OISHI HIROTO
IPC: H02M3/28
Filed: 1992-05-08
Abstract: PURPOSE:To improve the safety and reliability of a DC power unit by preventing the generation of a leakage current even when the capacities of constant-voltage elements of a surge voltage absorption circuit are set larger or even when either one of the constant-voltage elements short-circuits due to a surge voltage. CONSTITUTION:The series circuit of constant-voltage elements 8 and 9 acts on and absorbs a normal-mode surge voltage applied across the lines H and N of an AC power source 1 and the series circuit of the element 8 or 9 and a capacitor 10 acts on and absorbs a common-mode surge voltage applied across the line H or N and a frame ground FG. Since the two elements 8 and 9 and the element 8 or 9 and capacitor 10 act in series on the surge voltages, the withstand voltage and power capacity can be increased and, at the same time, since the capacitor 10 prevents a leakage current even when either one of the elements 8 and 9 are short-circuited, no leakage current flows to the frame ground FG and the occurrence of an electrical shock is eliminated.

Abstract: PURPOSE: To simply and cheaply form a large size pipe at the under part of a metallic pipe end, by holding the upper end of said pipe with a holding die in order to add a hydraulic pressure in said pipe by simultaneously lowering said holding die.  
     CONSTITUTION: A sudden hydraulic pressure 2 is added into a metallic pipe 1 of which an under part is fitted loosely into a vertical die 3 and an upper part is fitted closely into a holding hole 4 of a holding die 5. A part of the pipe 1, except the upper end of the pipe 1 held by the holding die 5, expands by the hydraulic pressure 2 causing the increase of its dia. and the decrease of its length. At this time, when the die 5, holding the upper end of the pipe 1, is lowered to press the upper end of the pipe 1 with the top of the holding hole 4 of the die 5, the lower outer peripheral part of the pipe 1 is made to fit closely to the inner peripheral surface of the die 3 so as to form a expanded pipe 6. Simultaneously, a stepped or tapered pipe-part 8 is formed between the expanded pipe 6 and the small dia. pipe 7 at the upper end of the pipe 1 held by the holding die 5.

Abstract: PURPOSE:To cope with a variation of an extracting flow rate, by adding a variation quantity per unit time of the extracting flow rate to a set value of a discharge flow rate, and increasing or decreasing the set value of the discharge flow rate. CONSTITUTION:In case when an extracting pump 5 becomes an operating state from a stop state, the extracting pump 5 is controlled by an extracting flow rate control meter 3 so that its extracting flow rate value Q2 becomes equal to an extracting flow rate set value 8. Therefore, a discharge flow rate value Q1 measured by a discharge flow meter 2 is decreased by an extracting flow rate value Q2 portion. On the other hand, a positive variation quantity DELTAQ is detected from the previous and the present extracting flow rates Q2 at every unit time by a differential operator 9, it is added to a discharge flow rate set value 4 by an operator 10, and a discharge flow rate target set value of a discharge flow rate control meter 3 is increased. Therefore, a control signal for obtaining a large discharge flow rate is applied to a discharge pump 1 by said portion, and accordingly, a variation of the discharge flow rate value Q1 can be reduced to the utmost.

Title: Production of rigid water-granulated slag
Inventor: KANEMATSU KINJI
IPC: C04B5/06
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To obtain the slag at a low cost and in a high yield without remodeling installations and without installing a new installation, by adding non-dried water-granulated furnace slag just after produced by the water granulation method to melted furnace slag in a specific rate. SOLUTION: The non-dried water-granulated furnace slag is added in an amount of 1 to 10 wt.% based on the total weight of the added mixture. The reduction in the amount of nitrogen which is dissolved in the slag and causes a foaming reaction on the water granulation and the lowering in the temperature of the melted slag are effective for the production of the rigid slag by the water granulation of the melted furnace slag. When the non-dried water- granulated furnace slag is added, the adhered water is evaporated as steam to contribute to the lowering in the temperature of the melted slag, and the steam is further impregnated into the melted slag and reacts with the dissolved nitrogen to release the nitrogen as nitrogen gas outside the system, thereby giving the dense rigid water-granulated slag. The non-dried water-granulated furnace slag is slag in a state lifted from a basket just after the water granulation treatment, and has a small amount of adhered water on the surface and water impregnated into spaces such as cracks and opened pores.

Abstract: PURPOSE:To estimate the positions of a spot light source and a pedestal by using a reference plane object whose shape is known to calculate various parameters of a measuring system based on this reference object. CONSTITUTION:A coordinate system 61 is considered which is fixed to a polygonal plane reference plate 60 whose shape is known. A position vector on this coordinate system is defined as rc, and feature points on the outline of the reference plate, for example, apexes of the polygon are defined as Q1, Q2...Qn and their coordinates are defined as rc1. The reference plate 60 is irradiated with a spot light source 1, and the plate and its shadow 4 are photographed by a sensor to extract a feature point R'1 of the image of the shadow 4 corresponding to a feature point Q'1 of the reference plate 60. The feature point Q'1 is extracted from the image of the reference plate 60 to estimate the position and the direction of the reference plate 60 in the space. If relations among the sensor, the light source, and the pedestal are unknown, they are estimated to improve the precision of measurement of an unknown object shape.

Abstract: PURPOSE:To improve a processing capability of a central control device by executing an existing stand-by switching processing, only in case an error caused by an element fault of a main storage device in a duplex main storage device has been detected. CONSTITUTION:With regard to an information read out of the same address (a) of a main storage device MM0, when an error is detected continuously by a parity checking circuit PC, an element fault detecting signal e2 is transferred to a central control device CC0.
