Title: Manufacture of sintered ore with high productivity
Inventor: NAGAI TADAHIRO
IPC: C22B1/16
Filed: 1980-10-23
Abstract: PURPOSE: To manufacture sintered ore with high productivity without deteriorating the quality by mixing blended starting material with a small amount of a linear or flaky iron source and sintering the mixture.  
     CONSTITUTION: When fine ore is sintered, to blended starting material is added ≤3wt% needlelike, spiral or flaky iron source, and they are mixed, controlled in humidity, and simultaneously converted into pseudogranules. This mixed starting material is charged into a sintering machine and sintered. By adding metallic iron, the pseudogranules are strengthened, and the space among the granules is maintained properly to enhance the gas permeability during sintering. The added needlelike iron source includes steel fiber having about 1:(20W100) ratio between the diameter and length.

Title: Furnace wall structure
Inventor: HARADA SUSUMU
IPC: F23G5/44
Filed: 1985-07-08
Abstract: PURPOSE:To reduce coefficient of thermal conductivity and cost of refractory bricks by utilizing fireclay bricks in which silicon carbide etc. having component particles oxidized at high temp. are contaminated as bricks composing the most inner part of furnace walls. CONSTITUTION:Components such as SiC4 etc. generating was when they are decomposed at high temp. are contaminated into fireclay bricks with low porosity such as chamotte bricks 11' etc. as shape of particles or powder and at that time, components such as SiC etc. are enabled to have purity lower than 50%. These bricks 11' are used instead of refractory bricks 11. Thereby, when clinkers 2 adhere heavily to walls by gas generated from SiC contained in bricks, they fall down by their own weight and are easily separated even when they adhere thinly. Owing to low purity of SiC etc., coefficient of thermal conductivity of said bricks is not sodifferent particulary from that of chamotte bricks and tensile anchor tip temp. is quite same as prior one and cost of bricks is not so high.

Title: Testing circuit of mos multiplexer circuit
Inventor: TAKEUCHI HIDEYO
IPC: G11C29/00
Filed: 1986-06-25
Abstract: PURPOSE:To judge a flaw accurately, by allowing the output of the gate circuit having a flaw of a multiplexer circuit to compete with the reversal output thereof. CONSTITUTION:For example, when a transmission gate 13 has a flaw due to the disconnection of an output wire, 'H' signals are outputted from output OT and test output TOT by charge due to the wiring capacity in an element or the capacitive coupling with a near signal wire at a time when a control input signal CH is applied and, therefore, though there is a flaw, there is possibility erroneously confirming normality. Then, a transmission gate 24 having resistance larger than each of the ON-resistances of transmission gates 11-14 constituting the multiplexer circuit 10 is provided to a flaw detection circuit 20. When a control signal TEST is inputted and an 'L' signal is superposed to the output OT through the gate 24, the output OT is converted to an 'L' signal and the test output TOT also changes from 'H' to an 'L' signal. When there is a flaw, this operation is always reversed before and after the signal TEST. Therefore, by measuring the state change of the output OT, a flaw can be judged without erroneous confirmation.

Title: Coating method of wire rod
Inventor: MOMOSE HIROTSUNE
IPC: C23C26/00
Filed: 1989-06-15
Abstract: PURPOSE:To perform beaded coating on a wire rod in an effective manner by forming a coated layer of ceramics material around a wire rod, by forming a groove of certain shape on the periphery of the coated layer, and by baking it thereafter. CONSTITUTION:After a coated layer of ceramics material is formed around a wire rod, on the periphery thereof, a desired certain form of, for example, a spherical or cylindrical groove is formed. The wire rod and the coated layer that has the groove formed around the wire rod are then baked, so as to harden the coated layer formed around the wire rod. In the baking process, the ceramics that forms the coated layer is melted and then solidified. Concentration force works on the groove formed o the periphery of the coated layer in the process, and a crack is generated around the groove as a basic point on the coated layer, whereby a beaded coated material is obtained. Otherwise, by promptly cooling the wire rod and the coating that has the groove to a room temperature and by forming the coated layer formed around the wire rod, a synthetic resin that formes the coated layer is contracted, and concentration stress works on the groove formed on the periphery of the coated layer, whereby a beaded coated layer can be obtained.
