摘要:
A heparin derivative in which at least 0.5% of the entire hydroxyl groups of heparin are in the form of an ester of the following formula ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 each represent a hydrogen atom or an alkyl group having 1 to 6 carbon atoms; a method for producing aforesaid heparin derivative which comprises reacting heparin with a halide or anhydride of an unsaturated carboxylic acid of the formula ##STR2## wherein R.sub.1, R.sub.2 and R.sub.3 are the same as defined above; and a method for imparting antithrombotic activity to a biomedical material, which comprises treating that surface of the biomedical material which makes contact with the blood with actinic light in the presence of aforesaid heparin derivative.

A DNA sequence comprising a polynucleotide segment consisting of a DNA sequence (A) shown below and a DNA sequence complementary thereto: ##STR1## wherein A represents deoxyadenosine-5'-phosphate, C represents deoxycytidine-5'-phosphate, G represents deoxyguanosine-5'-phosphate, and T represents deoxythymidine-5'-phosphate.The DNA sequence provided by this invention is derived from a rearranged immunoglobulin heavy chain variable (V.sub.H) region gene taken from the mouse hybridoma NL-1 cells which produce an antibody capable of commonly recognizing surface antigens of various human acute lyphocytic leukemia cells. Accordingly, if, for example, it is combined with a heavy chain constant (C.sub.H) region gene, a heavy chain can be produced which can recognize commonly various human acute lymphocytic leukemia cells in combination with a proper light chain. This would serve for the diagnosis and treatment of human acute lymphocytic leukemia.

Provided is a novel conjugated yarn which: has excellent stretchability; is provided with a sufficient strength; shows high transparency; provides a good tactile sense; and has moderate fit power. Also provided are a knitted fabric knitted by using such conjugated yarn and a clothing product using such knitted fabric. Also provided is a method of producing a novel conjugated yarn which: has excellent stretchability; is provided with a sufficient strength; shows high transparency; provides a good tactile sense; and has moderate fit power. A core-sheath type conjugated yarn of the present invention is a core-sheath type conjugated yarn, including: a core portion containing a polyurethane; and a sheath portion containing an elastomer, in which: the polyurethane includes a double-prepolymer type polyurethane obtained by causing a prepolymer having isocyanate groups at both terminals, which is obtained by causing a polyol and a diisocyanate to react with each other, and a prepolymer having hydroxyl groups at both terminals, which is obtained by causing a polyol, a diisocyanate, and a low-molecular weight diol to react with one another, to react with each other; and the core-sheath type conjugated yarn is obtained by conjugate spinning under conditions of a fineness of 18 to 110 dtex, a weight ratio of the core portion to the sheath portion of 95/5 to 60/40, and a drawing ratio of 1.5 to 4.0.

A power transmission mechanism comprising: a flexible power transmission element; a pair of a drive pulley and a driven pulley on which the flexible power transmission element is wound, each the pulley having a pin-embedding hole formed to extend from the outer circumferential thereof toward the center thereof, and a slit elongated in the circumferential direction of the pulley to extend to opposite sides of the embedding hole and communicating with the embedding hole; and a pair of columnar or tapered anchor pins each having a path hole penetrating the anchor pin across the lengthwise direction thereof to receive the flexible power transmission element inserted therein, wherein each the anchor pin receiving the flexible power transmission element in the path hole thereof is embedded in the embedding hole of the associated pulley under pressure, and the flexible power transmission element is thereby held on the pulley.
摘要:
The present invention relates to a collaboration apparatus between information processing systems for allowing a plurality of information processing systems to collaborate with each other without awareness of the difference in architecture, and an integrated information processing system in which a plurality of information processing systems are combined by using such a collaboration apparatus between information processing systems. In the case of allowing an SFA system (30) to collaborate with an ERP system (10) in the integrated information processing system including a plurality of information systems, an intersystem collaboration object (40) of the collaboration apparatus between information processing systems generates an active role (51) corresponding to a system of a collaboration origin and a passive rule (52) corresponding to a system of a collaboration target, generates a relating object (53) between these roles in accordance with collaboration information defining a communication method between information systems, and transmits a transaction between the active role (51) and the passive role (52).
摘要:
A weight and form sensing apparatus according to the present invention provides weight sensors on a base, in matrix pattern for instance. Each weight sensor has a load receiving portion on a top. Weight and form can be sensed by single weight and form sensing apparatus according to the present invention. That is, output values of the weight sensors are summed, so that an article put on the weight sensors can be detected. Also, the existence of the load on each weight sensor is determined based on output signal of each weight sensor, so that the bottom form and size of the article can be identified. The weight and form sensing apparatus according to the present invention can be preferably arranged into a feeding stream of the article because an arrangement of the sensors for identifying the form and size of the article does not interfere an arrangement of the feeding mechanism for the article.

These probes may be used for identifying pre-B cells. The invention further provides polypeptides translated from a transcript comprising a nucleotide sequence which is selectively expressed in pre-B cells or parts thereof, antibodies against these polypeptides and methods for the preparation and use of the polypeptides and antibodies raised against them.
摘要:
An illumination unit includes a distal end frame member having a through opening, a plurality of illumination sections, and a holding member which is arranged in the through opening and holds the illumination sections to incline the illumination sections at a desired angle with respect an opening surface of the through opening and to form a cascade along the axial direction of the through opening. The illumination unit includes a reflective member which is configured to reflect the illumination light emitted from the illumination sections toward the opening surface, the reflective member being held by the holding member to face the illumination sections and to apply the illumination light externally emitted from the illumination sections from the inside of the through opening via the opening surface.
