IPC: C21B7/06
Filed: 1982-05-31
Abstract: PURPOSE:To form a structural body stuck with granular refractories effective for relining of furnace walls on the inner side of the furnace wall by flaring the tubular leading end part fitted onto a guiding bar body which is inserted through the opening of the shell in the worn part of the furnace wall and is held there like petals by said bar. CONSTITUTION:The shell 1 in the worn part of a furnace wall is opened. If refractories 2 remain and there is a refractory wall 20, these are opened as well. A guiding bar body 5 is inserted into the furnace and an outward bending means 6 at the leading end thereof is held at the prescribed depth in the furnace by means of a supporting stand 7 or the like. A tubular body 8 provided with an arbitrary number of axial slits in the leading end part is fitted onto the body 5. When said body is forced into the furance by means of a cylinder device 10 or the like, the body 8 is bent outward from the tips thereof and is opened like petals. For example, if two tubular bodies 81, 82 are used, a stuck structural body 101 of two steps is formed in the furnace.

Filed: 1983-05-26
Abstract: PURPOSE:To reproduce accurately a digital signal without distortion by waveform shaping a transmitted digital signal and allowing this output not to be applied to a flip-flop set/reset by an output of a waveform shaping means for a prescribed time. CONSTITUTION:A digital signal from a communication line C is inputted to transistors 9, 10 via a transformer 8.

Abstract: PURPOSE: To attain safety by providing a temperature fuse that stops electric feed to a heating element through the breaking of the wire of the heating element or a heat sensitive element and operates at a temperature beyond the allowable range of the heating element or a higher temperature at which a melting layer melts.  
     CONSTITUTION: While the temperature of a heat sensitive element is low and the impedance of heat sensitive layer 10 of it is high with electric power switch 2  turned on, heating element 47 is turned on and the temperature of the carpet rises.  Then, when the temperature reaches the saturation temperature (dangerous state)  of the carpet exceeding the set temperature of variable resistor 18, the 3rd heating  resistance 41 is turned on through the operation of the 2nd SCR42, and consequently temperature fuse 3 is brown for its safey. In this state, in case that temperature  fuse 3 is not brown when the 2nd SCR42 is not in operation due to some reason,  the temperature of the heating element further rises and melting layer 46 melts, setting a short-circuit state. In accordance with the short-circuit point, the 1st or 2nd  heating resistance 4 or 44 is heated up to blow temperature fuse 3.

Title: Hollow cathode
Inventor: NORO TADASHI
IPC: H01J61/09
Filed: 1993-03-30
Abstract: PURPOSE:To prevent accumulated materials from adhering to a keeper electrode, a keeper lead, and a flange, peeling off, therefrom and being jumping out in discharge space and prevent insulation failure of a hollow cathode by providing a metal mesh and covering the keeper electrode, the keeper lead, and the inner face of the flange. CONSTITUTION:In order to start a hollow cathode, a gas for discharge is introduced into the inside of a cathode pipe 2 so as to heat the cathode part and at the same time voltage at hundred and some tens V is applied to a keeper electrode 5 through a keeper lead 6. When the temperature rises to about 1000 deg.C, gas discharge occurs between a cathode disk 1 and an electrode 5 and the discharge is kept between an electron emitting body 3 and the electrode 5. Substances accumulated due to sputtering adhere to the surfaces of the electrode 5 and the lead 6 exposed to a discharge space or on the inner face of a flange 7 come off later and are dispersed in the discharge space to possibly cause insulation failure. The insulation failure is therefore prevented by covering the outside parts of the above mentioned positions with a metal mesh 11.
