Abstract: A solidified residual iron within a blast furnace is suspended up by employing a shell suspending device fixed to a tuyere arranged in a lower end portion of an upper portion of a furnace body suspended by a lift jack and a solidified residual iron suspending band, thereafter is descended by employing the lift jack and is mounted on a horizontally moving table. Subsequently, the horizontally moving table mounting the solidified residual iron thereon is moved onto a furnace outer truck rail from a furnace inner truck rail so as to be taken out of the furnace by operating a center hole jack arranged near the furnace outer truck rail, whereby an operation of taking out the solidified residual iron within the blast furnace out of the furnace is economically performed for a short time.

Abstract: A method and lifting transfer apparatus for dismantling an existing blast furnace body by dividing it into a plurality of furnace-body ring blocks, and efficiently transporting each of the ring blocks to and from a furnace-body disassembly site and back to the hearth for assembly of a repaired or rebuilt furnace body.

Abstract: A method and apparatus for measuring a gas partial pressure in a living body on the basis of the principle of polarography. A gas partial pressure sensor includes a biomedical electrode inserted in the living body. A temperature sensor is further provided to measure a temperature of the living body. A polarographic current value measured by the gas partial pressure sensor is corrected to a current value at a reference temperature depending on the temperature measured by the temperature sensor. Then the gas partial pressure at the reference temperature is determined based on a working curve which represents a relationship between the corrected polarographic current value and the gas partial pressure at the reference temperature.

Abstract: Disclosed is a metal electrode for a living body, which comprises a noble metal wire an an insulating covering layer formed around the periphery of the noble metal wire. At least a part of the portion of the insulating covering layer falling in contact with the noble metal wire is composed of a crosslinked epoxy resin. The outermost layer of the insulating covering layer is composed of a polyurethane. Either or both of a part of the tip end and side face of the metal electrode is directly covered with a polyurethane porous membrane instead of the insulating covering layer.

Abstract: Medical appliances are continuously packed for sterilization thereof by the process wherein (1) bags having micropores in peripheral side portions thereof to be sealed, which micropores allow passage of a sterilizing gas and a high pressure steam but do not allow passage of germs, are formed from packing sheets; (2) medical appliances are inserted into the bags while the bags are formed; (3) all the peripheral side portions of the bags are sealed; and (4) the sealed bags containing the packed medical appliances are separated into packages each having the packed medical appliance.

Abstract: An electrode for living bodies consisting of a fine metal wire at least part of the surface of which is directly coated with a porous membrane having fine pores of an average pore diameter of greater than 0.01 .mu.m. The electrode makes it possible to measure the oxygen concentration in the blood vessels and in the living tissues with increased stability and improved response characteristics. Particularly good results are obtained when the porous membrane is a non-homogeneous structure using a cellulose acetate.
