Title: Controlling method for blowing inert gas to vacuum degassing unit
Inventor: OODERA MUTSUMI
IPC: G05D7/00
Filed: 1978-12-08
Abstract: PURPOSE: To exert continually constant control described in the title, by comparing detected rate of inert gas flow through each branch pipe with set flow rate, and by opening or closing a gas flow control valve so as to make the deviation zero.  
     CONSTITUTION: In blowing inert gas into molten steel, an arithmetic unit 12 corrects the temp. and, in addn., calculates the quantities, i.e., set value, of inert gas to be supplied to respective branch pipes 16 according to the signal, which is given by an indicator 11, and gives correctly the indicated flow rate to the respective branch pipe 16 by the association of a orifices 13, control valves 14 attached to the respective branch pipes 16. During operation, when the inert gas flow rate is decreased due to partial blockade etc. of a nozzle 9, and the flow of inert gas through the branch pipes 16 is decreased, the orifices 13 detect the flow, and the arithmetic unit 12 compares the detected value with the set value, and increases the degree of opening of the control valve 14 so as to make the deviation zero, hereby the rate of flow through the respective branch pipes 16 is continually kept correct.

Abstract: PURPOSE:To aim at enhancing the function of a reed valve, by extending the peripheral wall of a crank casing above a balance weight to form a balance weight housing, and by providing the reed valve in an intake-air passage defined by the peripheral wall as a side wall thereof. CONSTITUTION:When a negative pressure is effected in a crank chamber 3 due to ascending of a piston 11, a pressure variation is transmitted to a reed valve 25 to resiliently deform a valve element 28, and mixture from a carburettor 23 flows along a smooth surface of a balancer housing 20 formed above a balance weight 18 into a crank chamber 8 through an opening 27. In this arrangement, since an intake-air passage 24 is defined by the balancer housing 20 as a side wall thereof, the gap between the balancer 15 and the intake-air passage 24 may be eliminated. Accordingly, it is possible to restrain the reed valve 25 from separating from the crank chamber 8, and therefore, time delays between pressure variations effected in the crank chamber 8 and the opening and closing of the reed valve 25 may be reduced, thereby it is possible to aim at enhancing the function of the reed valve 25.

Abstract: PURPOSE:To prevent waving deformation of retainer rings which support both ends of a monolithic catalyst inside a cylindrical case by partially cutting out each of the retainer rings in order to absorb heat expansion which occurs when a catalytic converter is operated. CONSTITUTION:A monolithic catalytic converter 1 is constituted such that a monolithic catalyst 3 is placed inside a cylindrical catalyst case 2. The monolithic catalyst 3 is sandwiched in the axial direction 20 by the opposite end faces 11 and 12 of the cylindrical case via cushion rings 16 and 17 and retainer rings 18 and 19 which abut the upper end 14 and the lower end 15 of the catalyst, respectively, thereby being supported resiliently. The retainer ring 18 is an integral form compressing an annular flat part 26 and a cylindrical part 27 and has a partially cut-out part 28. The distance l at the cut-out part 28 between both the ends 29 and 30 is set to be a length corresponding to circumferential elongation of the retainer ring 18 caused by its thermal expansion when the converter is operated. The elongation may prevent exhaust gas from leaking from the cut-out part 28.

Filed: 1981-09-25
Abstract: PURPOSE:To eliminate the unstable operation of a comparator consisting of an N-MOS and to realize highly precise conversion, by setting the first comparing reference potential of a successive comparison type A/D converter at 3/4 reference voltage. CONSTITUTION:An anlog input 24 of a successive comparison type A/D converter turns on S1, S2 and S4 and is sample-held at a capacitor C1. Then S1, S3 and S4 are turned off with the S2 turned on, and the comparison with the reference potential 22 is carried out through a comparator 2 consisting of amplifiers Tr1 and Tr2 of an N-MOS. Then the output 23 is successively fed to a comparison controlling part to change the reference potential. The own bias of the Tr1 is set at 1.4V, and the comparing reference potential is set 3/4 reference voltage 5V with an input set at 5V. Thus the potential of a terminal C11 is set at 1.4-(5-3.75)V and positive. As a result, a forward current produced by a p-n junction does not flow to realize the use of an amplifier of high gain. In such way, a conversion is possible with high precision.
