Title: Synchronous followup device
Inventor: SUGIMOTO DAIKI
IPC: H04B1/707
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To enable the followup of path through a synchronous followup device by finding the average value of power of a correlative value outputted from a correlator, comparing that average value with a prescribed threshold value and changing the correlative length of the correlator crorresponding to the result. SOLUTION: An early correlator Corr E1 outputted from a normalizer 14E and a late correlator Corr L1 outputted from a normalizer 14L are respectively outputted to a power comparator 17. Then, an average circuit 20 of the comparator 17 finds the average value of power of the early correlative value Corr E1 and the late correlative value Corr Ll for fixed time. Next, a comparator circuit 21 compares the average value of this power with a threshold value Pow TH of power. When the average value of power is lower than the threshold value, a control signal C1 for increasing a cumulative number N of a cumulative adder 13E is outputted to correlators 10E and 10L. In this case, the constant N is made K-fold corresponding to the signal C1. Therefore, even when a received signal component is too less to follow up, the constant of the correlative length is adaptively extended and an S/N is improved.

Title: Manufacture of sintered ore
Inventor: INASUMI TADAHIRO
IPC: C22B1/20
Filed: 1981-08-26
Abstract: PURPOSE:To obtain with good productivity a sintered ore of a good quality, which is low in  FeO, high in a reducing property, ad also low in a low temperature reducing pulverization  ratio, by feeding firing gas having specific O2 concentration from an inlet of a zone to an outlet side, under a specific temperature condition, in an upper layer part firing zone. CONSTITUTION:In an upper layer firing zone of a lower suction system continuous sintering  machine, firing gas whose O2 concentration is >=16%, preferably 21% is fed to an inlet side of  the zone at >=800 deg.C gas temperature, and to an outlet side of said zone by gradually lowering  a temperature to an almost normal temperature. In this case, as for both the upper and intermediate layers, gas of a normal temperature is sucked from the material surface layer, and the temperature is raised when passing through a sintering completion layer, but the intermediate  layer is longer in its passing time and its temperature is raised enough. Also, as for a combustion temperaure of compounding fuel, the higher it is raised, the higher a combustion gas temperature is. Accordingly, since in ignition temperature of the compounding fuel is about 750 deg.C,  a gas temperature of the inlet side of the zone is set to >=800 deg.C. O2 concentration is held at  21% until it is sucked by the combustion zone, and although 21% is desirable, combustion is  caused by 16%. When a firing gas temperature is lowered graudally to the outlet side, combustion of the compounding fuel of the upper layer at a high temperature is suppressed.

IPC: B60N2/16
Filed: 1990-05-23
Abstract: PURPOSE:To effectively decrease jump-up and bottoming by providing an air feed valve operating means for opening an air supply valve when a seat exceeds a lower limit level while closing the same when the seat comes to a set level, and by providing an adjusting means for shifting the closing position of the air feed operating means. CONSTITUTION:After air is discharged from an air cushion, when a seat is occupied in a condition such that the seat is positioned at an NLD position in the vicinity of its lower limit level, an upper frame 1 exceeds the lower limit level LD so that a free link shaft 4a pushes an air working rod 20. Then, an air feed cam 19 is rotated about a pin 22 as a rotating axis so as to open an air supply valve 9 in order to raise the seat. Meanwhile, when the seat exceeds its upper limit level, that is, the opening position of a air discharge valve 14, the free link shaft 4a pushes an air discharge actuating rod 24. Then, an air discharge cam 23 is rotated about a pin 26 so as to open the air discharge valve 14 in order to discharge air from an air cushion 7. At this time, a rotary shaft 27a is rotated by a handle 29 so as to retract, for example, a movable shaft 27b, and accordingly, a stopper 27c also retracts so that the air feed cam 19 retards the position of closing the air feed valve 9. Accordingly, the air pressure in the air cushion 7 becomes higher so that the suspension becomes harder.
