Abstract: A thermoplastic polyurethane elastomer containing a very small amount of small grains, and having a high molecular weight and a narrow molecular-weight distribution. Such high-quality thermoplastic polyurethane is excellent in melt moldability and allows to prevent yarn breakage in producing fibers by melt spinning, for example. Such polyurethane elastomer can be produced by melt-polymerizing a prepolymer and a low-molecular diol at a relatively high temperature in a short period of time. This invention also provides an apparatus for producing the polyurethane elastomer, and fibers formed of said elastomer.

Abstract: In a winder provided with a control device capable of independently controlling rotational speeds of both motors for a friction roller having a winding package placed thereon and a traverse mechanism, a driving method for a winder comprising: obtaining a difference between an output of a first sensor for detecting a rotational speed of a package and an output of a second sensor for detecting a rotational speed of a friction roller, attenuating the difference to an adjustable value to prepare a correction value, subtracting the correction value from the output of the second sensor, and using the result obtained therefrom as a control input of the both motors to enable selection of a plurality of winding patterns.

Abstract: A process for manufacturing a thermoplastic resin composition by melt-kneading a thermoplastic resin and fine particles or an additive, includes: introducing gaseous and/or liquid fluid containing fine particles of at most 10 .mu.m particle diameter or an additive to an unmelted granular or molten thermoplastic resin moving bed; adhering or depositing the fine particles or additive onto said moving bed, while the fluid in the gaseous state is being discharged; and then successively melt-kneading a mixture of the granular resin with the fine particles or additive. This process can be combined with a subsequent shaping step continuously that follows. The process of the invention saves energy, raw materials and labor consumptions and yields shaped articles of high quality and uniformity.

Abstract: This invention relates to a microcapsule having a particle diameter of 2.about.300 .mu.m and comprising a substance acting to improve physiological conditions of human skin, for example, substances exhibiting such effects as skin whitening, aging preventive, humidity preservable, itch suppressive, pain-killing, or antiphlogistic ones, and/or aromatic agents contained within the filmy coating of synthetic high molecular substance. The microcapsule is not broken when making, processing, or laundering the textile structure, but is gradually broken when the textile structure is put on the human body, used for another purpose, or subjected to intentional application of friction or pressure thereto, and sustainedly releases acting substances contained therein.

Abstract: A process for producing a corn milling residue carboxymethyl ether salt comprises reacting a corn milling residue with alkali in the presence of an aqueous carboxymethylating agent solution to give a corn milling residue carboxymethyl ether salt with an average degree of substitution not less than 0.2. As the reaction medium, water alone is used in a proportion of at least 7 moles per mole of the corn milling residue. Carboxymethylation of the corn milling residue is accomplished evenly and smoothly.

Abstract: An automatic winder is provided with a tension sensor for detecting the tension of travelling yarn in each winding unit and a tensor for controlling the tension of yarn in accordance with a yarn tension variation signal provided from the tension sensor, to thereby eliminate the variation of yarn tension.

Abstract: A fluid-pressure detector comprising a pillow-like body capable of expanding and shrinking depending on pressure of fluid flowing in the pillow-like body, a detecting means for detecting an amount of expansion or shrinkage of the pillow-like body, and a connecting means for detachably connecting a detecting portion of the detecting means to an outer surface of the pillow-like body. Fluid pressure can be detected continuously and accurately both in the case of positive pressure and in the case of negative pressure. The detecting means is detachable from the pillow-like body, so that only the pillow-like body can be discarded while leaving the expensive detecting means as it is.

Abstract: In an automatic winder, presence or absence of a yarn on a package side and a yarn on a yarn supply bobbin side is detected during one cycle of yarn joining operation of a winding unit, and the winding unit after completion of a yarn joining operation is selectively instructed that an indication that yarn joining is impossible is to be made or that yarn joining is to be waited for.

Abstract: In an automatic winder having a plurality of winding units, a tension sensor for detecting the tension of yarn is provided in a yarn travelling path extending between a yarn feed side bobbin and a take-up side package. A take-up controller for controlling the yarn take-up rate in accordance with a signal provided from the tension sensor may be provided to the winding unit.

Abstract: A method of detecting a defect of a running yarn comprises steps of producing an electric signal in accordance with a winding speed of a yarn, correcting a reference value corresponding to a length of a defect of a yarn in accordance with the electric signal, and comparing the thus corrected reference value with a detection signal produced from a yarn defect detecting head thereby to detect a defect of the yarn included in the yarn during feeding.

Abstract: A device for sampling blood and measuring erythrocyte sedimentation rate. The device comprises a tube with one end closed, a blood sampling portion on an opened end of the tube and an erythrocyte sedimentation rate measuring portion extending from the blood sampling portion. A stopper is located on the open end of said tube, and may be pierced with a blood drawing needle. Finally a partition member is located within said tube and extends substantially over the entire length of said tube. Blood is directly sampled into the device and the device mixes the sampled blood with a solution of an anticoagulant with a high efficiency in the device. Accordingly, measurement of erythrocyte sedimentation rate can be performed quickly and easily.
