Title: Laminated stopper for pneumatic spring
Inventor: NISHIKAWA NORIO
IPC: F16F9/05
Filed: 1994-12-22
Abstract: PURPOSE: To exhibit characteristics close to the spring characteristic of a pneumatic spring even if the function of the pneumatic spring is lost by interposing at least one intermediate plate in an annular rubber-like elastic body concentric with a vent part in the pneumatics spring provided in the central part with the vent part communicating to an auxiliary air chamber. CONSTITUTION: A laminated stopper 3 built in a pneumatic spring consists of three layers and is provided to hold a fixed stopper distance at the neutral height of the pneumatic spring by a stopper cover metal 6 and pre-compression cover metal 7. Such laminated stopper 3 is composed of a rubber-like elastic body 3a, intermediate plate (annular rigid plate) 13, upper cover plate 6a and lower mounting plate 4a. The intermediate plate 13 is interposed in the rubber- like elastic body 3a under the free (non-adhesive) condition. Thus, when the laminated stopper 3 is axially compressed, the deflection is increase by the axial load and the spring constant is lowered so that characteristics close to the spring characteristic of the pneumatic spring are obtained.

Title: Fiber reinforced thermoplastic resin sheet
Inventor: KOYANAGI RYOTA
IPC: B32B27/04
Filed: 1993-12-28
Abstract: PURPOSE:To obtain a molded product excellent in surface smoothness even when a deep draw three-dimensional article is subjected to compression molding by closely bonding a resin film having an m.p. higher than that of a thermoplastic resin of a fiber reinforced thermoplastic resin sheet to the single surface or both surfaces of the sheet. CONSTITUTION:When a fiber reinforced thermoplastic resin sheet is preheated to a temp. range from the m.p. of the thermoplastic resin 5 of the sheet to below the m.p. of the resin film closely bonded to the surface of the sheet, the thermoplastic resin 5 is melted to become an easily deformable state and the resin film 4 is deformable but holds an unmelted state. When this sheet is set to a mold to be subjected to deep drawing, the extruded thermoplastic resin 5 in the sheet passes through the warp and weft yarns 6,7 of fibers for a reinforcing material to be ready to flow out the opposite surface of the sheet but the surface resin film 4 in an unmelted state stops the outflow of the resin 5. Since the resin film 4 is largely stretched but extremely low in rigidity, the generation of the peeling from the sheet or wrinkles is eliminated and surface smoothness is improved.
