Title: Manufacture of briquette for sintering
Inventor: MATSUNAGA YOSHIFUMI
IPC: C22B1/14
Filed: 1987-12-18
Abstract: PURPOSE:To reduce the amount of quick lime to be used by adding specific amounts of wet dust in which slurry concentration is specified to a sintering raw material, kneading the resulting mixture, regulating moisture in the raw material, and then briquetting the above. CONSTITUTION:Wet dust of 20-50% slurry concentration generated in a blast furnace, etc., and fed from a wet dust collector is added by 2-7% to a sintering raw material consisting of iron ore, ore fines as auxiliary material for component regulation, such as SiO2, CaO, and MgO, and solid fuel, such as carbon material. The resulting mixture is kneaded, while supplying the insufficiency of moisture, to undergo the regulation of moisture in the raw material to 2-7%, which is then formed into a briquette. By this method, the amount of quick lime to be used can be economized because the slurry from the dust collector is used as a binder for briquetting, and, as a result, the manufacturing costs for sintered ore can be reduced.

CONSTITUTION:When earth trouble is generated in a part of a pylon 2, the trouble current flows to the overhead earth wire 4 provided to the upper part of the pylon 2 to be separated in three directions I1a, I1b, I1c. In this case, current transformers 1a, 1b, 1c are connected so that the output voltages on the secondary sides of the current transformers 1a, 1b, 1c due to the separated currents become the same phase and the voltages B, D, F outputted from the current transformers and rectified by Zener diodes 7 are inputted to a phase discrimination circuit 8 and it is discriminated that the voltage waveforms thereof are the same phase. When the voltages B, D, F are the same phase and equal to or less than the set voltages of the diodes 7, an electronic switch 10 is operated to display the generation of trouble on a display device 11. By this method, a trouble point can be surely detected.

The tip of the cap nut 8 and the projecting stripe of the retainer 7 are arranged to be at roughly the same height so that there may be little projection above there. Thereby damage to the membrane can be prevented.

Title: Formation of tungsten nitride film
Inventor: NAKAMURA YOSHITAKA
IPC: H01L21/285
Filed: 1993-12-22
Abstract: PURPOSE:To reduce the damage of an Si substrate as a base and a metallic film by using a hydrazine compd. as a nitrogen compd. when a tungsten nitride film is formed on the substrate by thermal CVD using tungsten hexafluoride and a nitrogen compd. CONSTITUTION:A hydrazine compd. used as a nitrogen compd. is one or more kinds of compds. selected from among hydrazine, monomethylhydrazine, uns- dimethylhydrazine, sym-dimethylhydrazine, trimethylhydrazine, tetramethylhydrazine and ethylhydrazine. Since WF6 has high reactivity, it is liable to damage the material of a base in the early stage of film formation. The damage of the base can be, however, reduced because a reaction of WF6 with NH2 rapidly takes Place as compared with a reaction with NH3 used so far. The contact resistance between the material of the base and the objective formed WN film is also improved.

Title: Comparator
Inventor: NAKAMURA NORIHITO
IPC: H03K5/08
Filed: 1987-12-22
Abstract: PURPOSE:To provide a hysteresis to an input threshold value without giving any modification to a reference voltage by constituting an input circuit given to each input terminal of a differential amplifier by a Darlington connection circuit comprising PNP transistors(TRs). CONSTITUTION:Suppose that an input voltage V1 is lower than a reference voltage Vr, Trs 13, 14 of the input circuit at an inverting input terminal are turned on and TRs 11, 12 of the input circuit at a noninverting input terminal are turned off. In this case, since no collector current is supplied from the TR 12 to a TR 17, it is supplied from the base of an output TR 18 and its base potential is lowered. Thus, the output TR 18 is turned off, its output voltage V0 is at a 'high' level and a diode (Dod) 22 is in reverse-block state. When the voltage V1 rises and exceeds the voltage Vr, the TRs 13, 14 at the inverting input are turned off and the TRs 11, 12 at the noninverting input are turned on. Thus, the output TR 18 is turned off, its output voltage V0 is at a 'low' level and a diode (Dod) 12 is in conductive state. Then a hysteresis is given to the input threshold value.
