Granted: 1997-01-16
Abstract: PURPOSE:To avoid any soft error development due to alpha rays by a simple structure by the arrangement of a silicon rubber for cutting off the alpha rays in the required part. CONSTITUTION:A silicon rubber 5 large enough to cover the circuit surface of an IC 7 provided on the surface opposite to the TABIC 7 of a substrate 1 having multiple pads 2 on the surface using a bonding agent 10. Since the opposite surface of the IC 7 is fixed on a cap 8 using another bonding agent 9, the title chip carrier in high reliability capable of avoiding any soft error development due to alpha rays can be manufactured in such a simple structure cutting off the alpha rays by the rubber 5.

Abstract: PURPOSE:To secure a good bonding property of the fine metal wires to the leads by a method wherein the bonding areas of each lead are locally softened by applying ultrasonic vibrations to the bonding areas from the side of the back surface of the lead during the process of bonding of the fine metal wires and the leads. CONSTITUTION:Ultrasonic vibrations in the direction parallel to the back surface of a copper alloy lead 4 are applied to the bonding areas of the copper alloy lead 4 from the side of the back surface during the bonding process. The copper alloy lead 4 is already subjected to a work hardening hysteresis in addition to that a metal element is already added to the composition of the copper alloy led in order to secure the mechanical strength thereof, the hardness thereof is relatively higher than that of a copper wire 1 and the copper alloy lead 14 is hard to be plastically deformed at the time of bonding in the state intact. Thereof, by applying the ultrasonic vibrations to the bonding areas of the copper alloy lead 4 from the back surface of the lead 4, the bonding areas only are locally softened while the mechanical strength is sufficiently kept as the lead 4. By this way, the bonding property of the copper wire 1 to the copper alloy lead, whereto a silver plating is omitted, can be significantly improved and a significant reduction in the amount used of noble metal materials, such as gold and silver, can be attained.

Abstract: The invention concerns a device for the conversion of rotary into axial movement with planet rollers supported at an equal peripheral distance and driven by a drive shaft, and with a thrust body that is axially-displaceable through the planet rollers which are supported to be rotatable around their fixed axes in an axle-driven carrier and with drive groove via which the planet rollers, driven by their carrier, engage in at least one screw-type groove on the thrust body which is displaceable along the axis of the carrier; the device should be of simple construction and have as low a frictional loss arising from the movement conversion as possible. For this purpose, the carrier is fixed to the drive shaft rotating in its axle. There is no power transmission during movement conversion between the drive shaft and the carrier via the parts that are tooth-engaged in one another.

Abstract: Two Hepatitis C Virus envelope proteins (E1 and E2) are expressed without sialylation. Recombinant expression of these proteins in lower eukaryotes, or in mammalian cells in which terminal glycosylation is blocked, results in recombinant proteins which are more similar to native HCV glycoproteins. When isolated by GNA lectin affinity, the E1 and E2 proteins aggregate into virus-like particles. Cells bearing a mannose receptor or asialoglycoprotein receptor are capable of being infected with HCV, and supporting culturing of the virus.

Abstract: A polymeric blend particularly useful as a VI improver, which polymeric blend comprises a selectively hydrogenated asymmetric radial polymer comprising a plurality of polymeric arms containing hydrogenated conjugated diolefin monomer units and at least one block copolymer arm comprising a single polymeric block containing predominantly monoalkenyl aromatic hydrocarbon monomer units and a single polymeric block containing predominantly hydrogenated conjugated diolefin monomer units and a selectively hydrogenated linear diblock copolymer containing a single polymeric block containing principally monoalkenyl aromatic hydrocarbon monomer units and a single polymeric block containing predominantly hydrogenated conjugated diolefin monomer units. Both polymers in the blend will be selectively hydrogenated so as to convert (saturate) at least 95% of the ethylenic unsaturation initially contained therein. When used as a VI improver, the polymeric blend unexpectedly improves the thickening efficiency over and above the thickening efficiency that would be expected from a consideration of the individual contribution made by each of the polymers separately. The monoalkenyl aromatic hydrocarbon polymer blocks in both polymers is preferably styrene and the conjugated diolefin in both polymers is preferably isoprene. Preferably, both polymers are selectively hydrogenated so as to convert (saturate) at least 99% of the ethylenic unsaturation initially contained therein.

Abstract: Modified chimaeric antibodies, and antibody heavy and light chains, which comprise variable domains derived from a first mammalian species, usually mouse, and constant domains from a second mammalian species, usually human. Modification concerns the variable domains, in particular the framework regions of the variable domains. The modifications are made only in T-cell antigenic structures present in framework regions, and do not cover canonical structures or Vernier zone. The modifications adapt the amino acid sequences concerned to those occurring in corresponding antibodies derived from said second mammalian species. Thus, the modified chimaeric antibodies retain the original antigen recognition and binding properties but become less immunogenic to said second mammalian species, which improves their therapeutical utility with said second mammalian species. Recombinant DNA technology may be used to construct and produce the modified chimaeric antibodies. <MATH>

Abstract: PURPOSE:To enable speaking immediately when the hand set of a slave unit is picked up from a waster unit at the time of on-hook dialing at the cordless telephone set. CONSTITUTION:When an on-hook key 11 is operated for performing on-hook dial call origination, a signal based on the detected result is outputted from a key detecting means 161 and based on that output signal, a radio control means 164 drives a radio part 6 and transmits a radio wave from an antenna 7 to a hand set 2. When it is detected by the radio part 6 that the radio wave from a master unit 1 is received at the hand set 2 and a response signal is returned from the slave unit 2, the master unit 1 and the slave unit 2 are connected by radio. Therefore, when the slave unit 2 is picked up from the master unit 1, speaking is immediately enabled.

Abstract: The subject of the invention is a ball joint for motor vehicles with a bearing shell arranged between a joint housing and a ball head. The shell is provided at one end with elastically deformable ribs projecting from a stop surface. So that the ribs, after compensating for production tolerances, can absorb, in the elastically deformable zone, additional axial shock loads occurring in driving operation, it is proposed that the ribs be designed as square ribs, running radially, and separated by grooves from the stop surface adjoining their side walls, while the volume of each rib projecting above the stop surface, before mounting, is approximately equal to the free volume of the two grooves adjacent to it, so that the side walls of the grooves lying next to the stop surface act in the mounted condition as support walls for the elastically deformed ribs.
