Title: Prepreg ribbon for fiber-reinforced thermoplastic resin and prepreg
Inventor: FUKUSHIMA TOSHIHARU
IPC: B29B15/10
Filed: 1993-05-14
Abstract: PURPOSE:To obtain the subject prepreg having high uniformity and high degree of freedom in product design by laminating reinforcing fiber tow in a ribbonlike state in specific thickness to ribbonlike matrix resin layer having the same width, partially bonding in the length direction. CONSTITUTION:Reinforcing fibers 2 and 2' such as glass fibers, carbon fibers or Kevler fibers are bundled into a sectional circular shape to give tow, which is pressed by a roll, etc., flatly widened, formed into a ribbonlike state to give reinforcing fiber tow 3 having >=1.0mm thickness. The tow is superimposed on a matrix resin layer 4 having the same width in a ribbonlike state to make each side end part coincide with each other. The tow and the layer are partially bonded at bonding parts 5 and 5' in the length direction not to collapse or separate both the tow and the layer during handling to give the objective prepreg comprising the matrix resin to be readily impregnated into the reinforcing fibers 2 and 2', having stable impregnated state irrespective of shape of weaving and high degree of freedom in product design because of thinness.

Title: Floating-type magnetic head
Inventor: SUZUKI MASARU
IPC: G11B21/21
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To enable suppression of variation of a floating amount of a magnetic head against a change in an ambient air pressure by generating a negative pressure and a positive pressure on an air bearing surface (ABS surface) so as to obtain an appropriate shape thereof. SOLUTION: A slider 16 operating over a magnetic disk 30 at a floating amount fH is raised by an air flow A to maintain a position with an angle of elevation θ at a position where a balance with a suspension spring 18 is realized. In this case, a positive pressure FP and a negative pressure FN operate at the center of gravity G of the slider 16. The respective amounts of the positive pressure FP and the negative pressure FN are appropriately selected in accordance with a shape of an ABS surface. The positive pressure FP and the negative pressure FN become smaller with a smaller air pressure, resulting in a smaller lift and a reduced floating amount fH. However, since the fulcrum P of the suspension spring 18 is positioned closer to the outlet side of the air flow A than the center of gravity G, the floating amount fH can be maintained at the constant value while the angle of elevation θ is reduced.
