Abstract: Disclosed are biochips having a high detecting sensitivity with readiness in fabrication of microarray, and a method for fabricating the same, in which a solid support wound with fibers is immersed in a solution containing biomolecules to immobilize the biomolecules onto the fiber, and the individual fibers with the biomolecules immobilized thereon are straightened and arranged. The arranged fibers are embedding with a defined material and cut in a direction perpendicular to the lengthwise arrangement direction of the fibers to obtain thin chips. The chips are placed on a substrate to remove the material used for embedding and thereby remain fibers with the immobilized biomolecules on the substrate. This biochip fabrication method immobilizes a great number of biomolecules onto the fibers having a large surface area to enhance the detection sensitivity and allows production of a great number of substrates with an array of biomolecules immobilized simultaneously.

Abstract: A tennis trainer includes a generally L-shaped arm having a ball holder at one end and pivotally engaged to a support at the other. Impact against the ball in a direction axially along the ball-supporting section of the arm is initially absorbed by a resilient section of the other section of the arm. A housing on the support includes a slot through which the arm extends and a rotatable cylinder to which the arm is secured. Bias springs oppose rotation of the cylinder and hence the arm. The housing is mountable upside down to permit the trainer to be used for back hand practice or for left handed fore hand practice. Various bending of the arm and vertical positioning of the support permits the ball to be positioned at various heights and positions.
