  • Patent number: 6512388
    Abstract: An IC socket with good durability that permits electrical tests on IC to be performed accurately over a long period of time is provided. An elastically deformable metal plate 12 is fixed within a spring accommodating portion 9 of a support board 2. The metal plate 12 is such that a plurality of spiral cantilevers 19 are formed so as to correspond to bumps 21 of the IC 10, and the flat tip 19a of the spiral cantilever supports an insulative resin film 3. When the IC 10 is pressed by an IC pressing part 54 and the bump 21 of the IC 10 flexibly deforms the spring part S via the insulative resin film 3, a contact pressure due to the elastic force of the spring part S occurs in the contact area between the bump 21 and contact pad 11.

  • Patent number: 6509148
    Abstract: Disclosed is a method for fabricating biosensors, using hydrophilic polyurethane. Bio-active reagents, including enzymes, antibodies, antigens, cells and receptors, are mixed with hydrophilic polyurethane and the mixture is directly coated over a signal transducer to form a sensing film which serves as a signal detector. The method using hydrophilic polyurethane allows the simplification of the fabrication of biosensors without conducting complicated chemical reactions and washing steps, such as crosslinking. The bio-active reagent entrapped within the hydrophilic polyurethane film can retains its high activity for an extended period of time and the intrinsic potentiometric response of the underlying ion-selective polymeric membrane is not affected by the bio-active reagent immobilized polyurethane film coated on its sensing surface. Therefore, the biosensors are superior in specificity, selectivity, and stability.

  • Patent number: 6505993
    Abstract: A method and a device for braking vehicles, in particular race car vehicles at the edge of a racetrack, whereby an elastic, safety wall consisting of individual elements linked together movably like a chain and extending far beyond the critical location is arranged in a clearance adjacent to the critical location of the racetrack. A vehicle coming off the racetrack and colliding with the safety wall is braked by the elastic movement of the safety wall with the vehicle. This inexpensive method of manufacturing a safe safety wall guarantees linear and soft deceleration of a vehicle, greatly improving the safety of the race car drivers.
