The present invention provides an electrode material in which unevenness in a supporting amount of a carbonaceous film is less when using an electrode-active material having a carbonaceous film on a surface thereof as the electrode material, and which is capable of improving conductivity, and a method for producing the electrode material. The electrode material includes an aggregate formed by aggregating an electrode-active material in which a carbonaceous film is formed on a surface. In the electrode material, an average particle size of the aggregate is 0.5 to 100 &#x3bc;m, a volume density of the aggregate is 50 to 80 vol % of a volume density in a case in which the aggregate is a solid, and 80% or more of the surface of the electrode-active material is covered with the carbonaceous film. Alternatively, the electrode material includes an aggregate formed by aggregating electrode-active material particles in which a carbonaceous film is formed on a surface. In the electrode material, an average particle size of the aggregate is 0.5 to 100 &#x3bc;m, a pore size (D50) when an accumulated volume percentage of a pore size distribution of the aggregate is 50% is 0.1 to 0.2 &#x3bc;m, and porosity of the aggregate is 15 to 50 vol % with respect to a volume in a case in which the aggregate is a solid.

A crude oil processing method is provided wherein a membrane module is immersed in the crude oil contained in a processing tank and the crude oil is pressurized or driven by gravity for gravitational filtration, thereby to pass through the membrane, with the dehydrated oil that has passed being taken out through an oil collecting pipe. According to this method, a high degree of separation and removal of water content from the crude oil can be carried out regardless of the properties of the crude oil, and muddy matter can also be separated and removed.

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.

Apparatus for continuously packing medical appliances for sterilization

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.

Nonwoven fabrics are made by continuously expelling a high pressure liquid jet stream in the form of a film through a slit-shaped nozzle onto a web placed on a support.

Method for making nonwoven fabric and product

Polyolefin fibers containing at least 70% by weight of polypropylene fibers having a denier of at least 0.5 and a birefringence of at least 2.5 .times. 10.sup.-.sup.2 are formed into a sheet. The sheet is then frictionally calendered in the dry state at a frictional ratio of at least 15% and at a temperature in the range from 90.degree.C to 160.degree.C whereby an insulating paper having excellent air-impermeability and oil-resistance is obtained.
