Title: Method for tapping at furnace bottom
Inventor: IKEMIYA HIROYUKI
IPC: F27D3/14
Filed: 1989-06-13
Abstract: PURPOSE:To prevent the leakage of a molten metal during treatment and to safely and easily execute tapping at a furnace bottom by packing laminar refractory powder consisting of refractory powder of an upper layer having a high m.p. and high sintering temp. and refractory powder of a lower layer consisting of silica sand into the tap hole at the furnace bottom. CONSTITUTION:The laminar refractory powder consisting of the high refractory powder 4 having the high m.p. and sintering temp. as the upper layer in contact with the molten metal and the relatively inexpensive silica sand 5 as the lower layer is packed into the tap hole 1 at the bottom 2 of the converter and is held by a gate 6 having an opening/closing mechanism. For example, MgO+CaO +Al2O3, MgO+SiO2, C+MgO, etc., are used as the above-mentioned high refractory powder. The leakage of the molten metal during the treatment is surely prevented in this way. Further, the above-mentioned high refractory powder 4 forms a relatively soft and thin sintered layer during refining. The gate 4 is, therefore, opened by actuating a cylinder 7 of the above-mentioned opening/ closing mechanism 3 upon ending of the refining, by which the above-mentioned laminar refractory powder is broken down by the static pressure of the molten metal in the converter and is easily tapped from the bottom of the converter.

Title: Optical fiber flowmeter
Inventor: INAO KIYOHARU
IPC: G01P5/01
Filed: 1980-10-28
Abstract: PURPOSE:To obtain a flowmeter utilizing the nature of an optical fiber by feeding the output of an optical fiber inserted into a tube with a fluid flowing therein to a photoelectric converter and a comparator circuit to obtain an output corresponding to the oscillation frequency of the fluid. CONSTITUTION:An optical fiber 4 for receiving the output of a light source 3 such as laser is passed through a sensor section 6 in a tube 5 where a fluid flows. The output of the sensor is converted into an electrical signal with a photoelectric con- verter 7 and after passed through a rectifying circuit 9, compared with a constant voltage with a comparator circuit 10 to obtain a pulse output. With such an ar- rangement, although there is an amplitude modulation 7 in a part of the optical fiber contacting the fluid due to an oscillation frequency thereof resulting from a micro-bending loss attributed to vibrtion thereof, the utilization of the output Vout corresponding thereto provides an optical fiber flowmeter with improved characteris- tics including explosion proof and free from influence of electric noise.
