Abstract: A bearing condition monitoring device is a bearing condition monitoring device for monitoring a condition of a thrust bearing for holding a rotational shaft in a thrust direction. The bearing condition monitoring device includes a first temperature sensor for measuring a temperature of the thrust bearing, and an arithmetic device for counting a frequency at which an evaluation index of a thrust load on the basis of a measurement value by the first temperature sensor exceeds an allowable value, and for outputting an abnormality in the condition of the thrust bearing if the counted frequency exceeds a threshold. The arithmetic device may count, as the frequency, only a case where a state in which the thrust load exceeds an upper limit load continues for not less than a predetermined time.

Abstract: A method capable of bonding lengthy horizontal plate materials and lengthy vertical plate materials to each other without skill of a worker and with uniform and beautiful finish, and a press-bonding jig used for the method. The press-bonding jig is set at a workbench, which has a vertical wall section for positioning lengthy horizontal plate materials and lengthy vertical plate materials, or at a member disposed around the workbench to press and fix the respective plate materials to each other along edges thereof, comprising a frame having a sufficient length to support the plate materials and holding air cylinders for actuating rubber pads in a pressing direction, and means for starting and stopping the air cylinders. The press-bonding jig is used to made complicated manual fixing operation needless and enables bonding in a short time with a beautiful finish.

Abstract: Crude immunoglobulin G isolated from human blood plasma is treated according to a conventional technique (such as the tricalcium phosphate adsorption method) to remove aggregates therefrom to such an extent that they are not detectable by gel filtration analysis. In order to produce an aqueous solution of immunoglobulin G having a reduced anticomplementary activity, the resulting solution is then filtered through a porous polyolefin membrane having a pore size larger than the molecular size of immunoglobulin G, in the presence of a stabilizer having surface activity. The aqueous solution of immunoglobulin G so produced is suitable for use in intravenous injection because its anticomplementary activity is low.

Abstract: Surface-modified cellulose acetate filaments having a microporous structure located in the peripheral surface layer thereof are prepared by bringing non-modified cellulose acetate filaments which have an average degree of acetylation of 50 to 62% into contact with an organic solvent which is capable of dissolving or swelling the non-modified filaments and by rapidly evaporating the solvent from the filaments. The microporous structure causes the surface-modified filaments to exhibit a desirable silklike touch and an increased intensity in dye exhaustion of from 1.1 to 2.0 times that of the non-modified filaments.

Abstract: A nonwoven fabric having no pattern and composed of 100% synthetic fibers, wherein individual fibers are held together by three-dimensional entanglement into a stabilized sheet form without being subjected to any bonding treatment, which nonwoven fabric has a structure characterized by a specific volume of the nonwoven fabric of 3.5 cm.sup.3 /g or less, a bending index (in terms of R) of individual fibers of 4.0 or more, and a strength efficiency (in terms of S) of the nonwoven fabric of 90% or more. Such a nonwoven fabric has excellent properties which are comparable to conventional woven fabrics in not only hand but also practical performance characteristics. This nonwoven fabric is manufactured by a method which comprises placing on a substantially smooth supporting member a web, 35 to 170 gm/m.sup.

Abstract: A wet formed web is overfed onto a running net by a liquid stream type web feeding apparatus so as to place the web into folded condition which is then subjected to regeneration and aftertreatments.

Abstract: A feeding apparatus for a sheet-like material is disclosed wherein means for introducing a rectified liquid stream are oppositely provided on both sides of the inlet portion of a slit type guide passage for the sheet-like material.
