  • Wooden base plate
    Patent number: 4631218
    Abstract: A base plate including an upward projecting peripheral rim and slots on the edge of the rim. The plate consists of a first, preferably flat unit made of wood and a second component connected to it and made of solid wood in the form of a composite frame consisting of three or more parts. Each part of the frame is dried to a very low moisture content and then heat-treated so that the pith fibers are sealed by resin released from the wood. The surface of each part of the frame is also treated with varnish or a similar substance which seals the surface pores of the wood. Each part of the frame is so arranged that the grain of the wood coincides essentially with the height direction of the plate. A reinforcing element prevents the warping of the wood caused by internal stresses in the wooden material.

  • Thermoplastic resin sheet
    Patent number: 4617207
    Abstract: Disclosed herein are thermoplastic resin sheets having a thermal shrinkage within .+-.0.3%, and a process for producing thermoplastic resin sheets by co-extruding a first thermoplastic resin and a second thermoplastic resin which is nonadhesive to the first thermoplastic resin, into a sheet-like structure so that the first thermoplastic resin is covered on both surfaces thereof with the second thermoplastic resin and then peeling off the resulting outer layers of the second thermoplastic resin B to obtain a sheet of the first thermoplastic resin. The thermoplastic resin sheets obtained in accordance with the above production process have an extremely small thermal shrinkage, undergo an extremely low degree of mechanical strain, and exhibits a little optical anisotropy. Because of the small thermal shrinkage, they may be used in liquid crystal displays (LCDs), poultice or sticker.
