Abstract: PURPOSE:To obtain a copper bonding wire for semiconductor elements with excellent wiring properties subject to favorable loop formation in a bonding process by a method wherein a copper fine wire is annealed so that the elongation percentage thereof may come within the range of 3-15%. CONSTITUTION:A high purity copper exceeding 99.999 weight% is cast by vacuum-melting process and after rolling the ingot thereof, wire-drawn at the room temperature and then intermediate-annealed to draw fine copper wire in the final diameter of 25mum. Next, when the high impurity copper is continuously annealed in inert gas atmosphere to draw the fine copper wire so that 1000 each of semiconductor multiterminals making a gap of 2mm between an electrode on a silicon semiconductor element and an outer lead may be connected by an automatic bonder to examine respective specimens using a real object microscope, the normal shape describes a loop such as a copper bonding line 7 between the electrode 3 on semiconductor element 2 mounted on a stem 1 and the outer lead 4. Said results can be attained by annealing the copper fine wire so that the elongation percentage thereof may come within the range of 3-15%.

Abstract: A cavity floor is formed by placing on a structural floor bottom a flexible floor mold which has leg forming portions arranged in an array with generally planar portions extending between and surrounding the leg forming portions. A flowable substance is applied over the mold, which subsequently hardens to form an upper floor having a plurality of legs defined by the leg forming portions, with a cavity region therebetween. The planar portions of the flexible floor mold permit adjacent leg forming portions each separately to contact the floor bottom under the weight of the applied flowable substance, even if the floor bottom is uneven.

Abstract: The present invention resides in an improved inflator for inflating a vehicle occupant restraint (12) such as an air bag. The inflator has an igniter (40). The igniter (40) comprises a container (130) which contains an ignitable particulate output charge (152). The particulate output charge (152) is retained within the container and occupies only a portion of the container. The container (130) thus has a free volume (154) equal to about 25% to about 75% of the volume of the container. The output charge (152) has a burn time in the range of 5-100 milliseconds. The container has at least one orifice means (136) closed by a rupturable disk (138). The orifice means (136) has an orifice area which is sized to contain the output charge (152) within the container (130) until at least a substantial portion of the output charge ignites. This provides a low brisance ignition.

Abstract: An apparatus for locking a horizontal plasticizing cylinder to the carrying block of the injecting unit of an injection molding machine having two cylinder-locking sliders which are disposed on opposite sides of the axis of said cylinder and are radially movable by means of hydraulic cylinders. In a locking position, the sliders extend in diametrically opposite recesses of the plasticizing cylinder. A shaft for driving the feed screw of the plasticizing unit has a coupling section which is formed with a radial guide groove, in which a screw-locking slider is radially displaceably mounted, the screw-locking slider being non-rotatably connected to the shaft. A coupling bridge is secured to the upper one of the cylinder-locking sliders. When the feed screw is in a desired angular position said coupling bridge is coupled to the screw-locking slider so that one cylinder-locking slider and the screw-locking slider are simultaneously moved to their locking positions.

Abstract: PURPOSE:To improve heat recovery efficiency and to prevent a breakage of a heat exchanger cylinder due to partial heating by forming an endothermic passage in such a manner that the sectional area is increased gradually from the middle portion toward an inlet portion and an outlet portion. CONSTITUTION:The lower wall 12 of a heat exchange cylinder 2 is formed to be lowered in the middle in such a manner as to project downward more towards the middle portion 10 of an endothermic passage 3, seen from the longitudinal direction, and the upper wall 14 is formed to be flat. The endothermic passage 3 is formed in such a manner that the cross sectional area thereof is decreased gradually from an inlet portion 8 toward the middle portion 10, and increased gradually from the middle portion 10 towards an outlet portion 11. By this arrangement, the flow speed of a heat recovery liquid is increased so as to prevent local heating of cooling water near an inlet pipe and make cooling uniform because air bubbles are not generated. Cooling water becomes turbulent in a gradually expanding portion extending from the middle portion 10 to the outlet portion 11 to promote contact of cooling water with the heat exchange cylinder 2. Accordingly, the heat recovery efficiency can be improved and a breakage of the heat exchange cylinder 2 due to partial heating can be prevented.

Abstract: The invention relates to the direct detection of human papillomavirus DNA. The recently developed polymerase chain reaction has been modified in order to improve sensitivity and specificity. It is possible, by choosing suitable oligonucleotide primers (amplimers) and reaction temperatures, for individual HPV genes to be identified among the total cell 4 DNA and amplified to such an extent that non-isotopic detection is possible. In addition, the use of reverse transcription allows deliberate amplification of spliced mRNA and thus an indication of premalignant or malignant states or lesions.

Abstract: This invention relates to processes which are used to produce, isolate, and characterize human rotavirus/animal rotavirus reassortants and to produce live attenuated vaccines and vaccine precursors. In the present strategy there is involved the new use of either (1) high titer hyperimmune antisera or (2) monoclonal antisera to select reassortants with the desired human phenotype. A point of novelty is the finding that antiserum or monoclonal antisera alone, so long as it possesses high titer neutralizing activity against only the 34-38Kd glycoprotein or of the animal parent, is sufficient to use for selection of reassortant rotaviruses with human phenotype. Also, the novel products are live attenuated vaccine precursors and vaccines.
