Title: Treatment of electric furnace slag
Inventor: HOSHINO KAZUHISA
IPC: C03B37/06
Filed: 1988-07-13
Abstract: PURPOSE:To manufacture slag wool capable of being utilized effectively for building materials and the like by a method wherein molten electric furnace slug, retrieved by separating the molten electric furnace slag or a valuable metal, is added with metallic oxide or non-metallic oxide. CONSTITUTION:In order to retrieve the valuable metal of reduced iron or the like from electric furnace slag, heat generating reducing agent, consisting of the principal agent of aluminum ash containing metallic aluminum, which is added with the small amount of sodium chloride and calcium fluoride, is employed and a slag cradle 1 is filled with molten electric furnace slag while said heat generating and reducing agent is blown through a lance tube 2 employing nitrogen and the temperature of the slag is risen to obtain molten steel 3 in the bottom of the slag cradle 1. A molten steel take-out plug 4 is pulled to tap the molten steel 3 and, thereafter, silica sand is blown into remaining slag 5 through the lance tube 2 employing nitrogen.

Title: Control of gas cutoff valve
Inventor: MATSUSHIMA TETSUHIKO
IPC: F16K37/00
Filed: 1990-07-03
Abstract: PURPOSE:To prevent generation of an abnormally large negative pressure by supplying a small quantity of gas to the downstream by switching a cutoff valve in every predetermined period when a signal from a pressure detecting means becomes less than an atmospheric pressure. CONSTITUTION:A gas meter has a cutoff valve 5 and a pressure detecting sensor 8. A cutoff 5, an action detecting sensor 5a, a flow sensor 7, a pressure detecting sensor 8, a manual restoration and a disconnection switch 9a, 9b, and a display part 10 are connected with a CPU 12 comprising a one chip microcomputer or the like through an in/out interface 11. The cutoff valve 5 keeps a valve body released normally, but once an output of the flow sensor 7 or pressure detecting sensor 8 is determined to be abnormal, a flow passage is cutoff by closing the cutoff valve 5, and the output of the pressure detecting sensor 8 is monitored in every predetermined period after that. When the valve of the pressure detecting sensor 8 is lower than a set value, a restoration pulse is sent to the cutoff valve 5 to release the flow passage, a cutoff pulse is applied after sending a small quantity of gas to the downstream, and the cutoff valve is closed again, so the monitoring by the pressure detecting sensor 8 is repeated.

Filed: 1989-07-06
Abstract: PURPOSE:To hinder breakage of a collector part by enhancing its mechanical strength against the local thermal expansion and contraction of the collector wall due to uneven incidence of electron beam while the heat radiation from the outer peripheral wall is maintained in good performance. CONSTITUTION:A collector part is previously sliced into a plurality of blocks 11a-11c, 12a-12d, which are jointed together hermetically, and No.1 circumferential groove 17 is formed at the periphery of each block while No.2 circumferential groove 18 is formed in the hermetic joints 13a-13f. Further a number of axial grooves 14 are formed in the tube axial direction. The No.1, No.2 circumferential grooves 17, 18 formed in each block 11a-11c, 12a-12d are so dimensioned that D1>D2 and W1<W2, where D1 is depth of No.1 groove, W1 width in the axial direction, D2 the depth of No.2 groove, and W2 the width in the axial direction. This causes reduction of the thermal stress in the part with No.2 circumferential groove 18 to hinder breakage of the collector part likely at the time of operation, which should enhance the reliability.

Abstract: PURPOSE:To hold sensitivity of a polarized electromagnet device, by a method wherein induced flux of a coil is prevented from passing through a permanent magnet and acting as attractive force of an armature to be reciprocated in the horizontal direction. CONSTITUTION:Lateral pieces 3, 4 of an outer U-shaped yoke 1 and lateral pieces 7, 8 of an inner U-shaped yoke 5 are opposed through a non-magnetic body 9 of plastic resin or the like.

IPC: H04B1/707
Filed: 1990-07-04
Abstract: PURPOSE:To reduce mis-detection of correlation peak due to the effect of a crosstalk wave and to improve the communication quality by comparing a spurious level with a correlation peak level resulting from peak holding and integrating a correlation output so as to demodulate a data. CONSTITUTION:Peak detection and hold sections 4, 4' detect a correlation peak or spurious peaks x1-x5 within a generation period T of the correlation peak and implement holding. The peaks x1-x5 are outputted at a succeeding period T. Low pass filters 5, 5' are filters having a cut-off frequency equivalent nearly to a transmission speed K of information to integrate the peak outputted from the sections 4, 4'. Then a data comparison section 6 compares a correlation peak level with the spurious level. As a result, when the former level after integration is larger than the latter level, the data is demodulated without any error. Thus, mis-discrimination of the correlation peak and spurious radiation due to a crosstalk wave is avoided.
