Abstract: The present specification describes a process by which a blood substitute (hereinafter referred to as "HemoSafe") is derived from uniformly stabilized monomers and polymers of deoxyhemoglobin in its tight (T) conformation, with oxygen affinity similar to that of human blood. Two classes of HemoSafe are derived respectively from animal-hemoglobin and human-hemoglobin. HemoSafe (animal) differs from HemoSafe (human) in that it is free of polymers in order to reduce potential immunogenicity if used in man. Both types of HemoSafe may be derived in the following manner. The stabilized deoxyhemoglobins are converted to their carbonmonoxy derivatives (CO-HemoSafe) which are then stable under pasteurization conditions to render them viral disease transmission-free. CO-HemoSafes are stable for 2 months at 56 DEG C in either the solution or the freeze-dried state. For transfusion CO-HemoSafes are easily oxygenated under sterile conditions by photoconversion yielding oxy-HemoSafe. In addition a transfusable met-hemoglobin derivative for treatment of cyanide poisoning, is derived by converting oxy-HemoSafe to met-HemoSafe.

Abstract: A beverage infusion device (10) for preparing an individual cup of an infusible beverage such as coffee and tea. The device includes one or more porous pouches (12) containing infusible material permanently or removably secured to a rotatable, hand held shaft (11), with the pouches extending radially outwardly from the shaft and dimensioned to fit within a conventional beverage cup or mug. In use, the device inserted in a cup of hot water and the shaft is rotated between the thumb and finger of the user in alternating clockwise and counter-clockwise directions. Upon rotation of the shaft and the pouches secured to the shaft, a centrifugal flow pattern is created in water which enhances the efficiency of extraction of the infusible material. When the pouches are permanently secured to the shaft, the entire device is discarded after use. When the pouches are removably secured to the shaft, the pouches are separated from the shaft after use and discarded, with the shaft portion of the device being reusable.

A chip electrode comprises an Al or Al alloy film, and the joint surface of a metal member comprises a noble metal plated film. The chip electrode and the metal member are jointed metallically with an Au bump in a thermal process, with an Al film in an Au/Al joint surface whose area is 80% or more being an Au Al alloy layer over the entire thickness direction. All Al under the joint part of a transistor package is allowed to be an alloy so that the strength of an Al electrode/Au bump/electrode lead joint part is improved, resulting in a structure under a compression stress, for higher reliability.

Abstract: A jig for attachment and detachment comprises a frame. When the jig is set on the surface of a printed circuit board, a connector on the printed circuit board can be received in a connector receptacle opening defined at the lower end of the jig. The frame is designed to stand on the surface of the printed circuit board surrounding the connector. An electronic component can thereafter be inserted in an insertion opening defined at the upper end of the frame. The inserted electronic component is guided, by a guide passage defined in the frame, from the insertion opening toward the connector receptacle opening. The guided electronic component is received on the connector. The guide passage serves to allow the input/output pin of the electronic component to reliably enter the socket of the connector without any interference. An operator is released from careful observation for alignment of the electronic component with the connector with his own eyes.

Abstract: A cryogenic distn. process (fig.1) is used to separate air into gaseous and/or liq. oxygen and nitrogen. The process takes a feed of dry, purified compressed air (100) and uses two distillation columns (920,921) in thermal contact and operating at different pressures. The higher press. column (920) is the lower one of the two. The distn. system separates the feed air into an N2 overhead (30,300) from the top of the high-press. column and an O2 bottoms (20,22,50,200) from the bottom of the low-press. column. In the process, part (126) of the feed air (100) is condensed to give a liquid air stream (1342) which is fed as reflux (136) near the top of the low-press. column (921). A waste gas stream (40,400) is removed from the top of the column, and has a mole fraction of nitrogen of less than 0.95. The removal of the waste gas (40) should take place not more than four theoretical stages above the feed point of the impure reflux stream (136).

Abstract: PURPOSE:To provide the thrust roller bearing with a race excellent in durability and low in manufacturing cost by forming the cross section of a raceway track section in the direction of a diameter into a circular arc shape the center section of which is projected out to the rolling face side. CONSTITUTION:When the bearing is subjected to thrust load in a state that a raceway track section 13 is brought into contact with a rolling face, the center section of the raceway track section 13 is elastically and linearly deformed while being adjusted to the rolling face, so that the raceway track section 13 is thereby brought into contact with the rolling face in a sufficiently wide area. Therefore, a contact section will never be subjected to great bearing stress. Even when the rolling face is not parallel with the reference plane 14 of a circular ring section 11 by unbalanced loading, the elastically deforming section of the raceway track section 13 is deformed as the rolling face is deflected. Therefore, similarly as each roller is sufficiently processed by a crowning operation, the occurrence of edge load can be prevented, which is caused by the contact of the circular ring section 11 with the end periphery of each roller in the axial direction.
