  • Patent number: 5451279
    Abstract: A method for joining two ceramic sintered bodies with a joining layer. A magnesium layer is deposited on the ceramic sintered bodies to form a magnesium nitride layer. The joining layer has a component in common with a base component of the ceramic sintered bodies. The laminate is heat treated under conditions that convert the joining layer into a material substantially identical to that of the ceramic sintered bodies, whereby a homogeneous strong laminate results. The ceramic sintered body may be either an oxide, carbide or nitride. The joining layer is a metal corresponding to the base material of the ceramic sintered bodies. After joining, the joining layer is then nitrided. The resulting laminate has improved strength, and heat and corrosion resistance properties.

  • Patent number: 5448026
    Abstract: A double-axis key switch has a key cap with a pair of key stems which slide into a housing to actuate a pair of switches. The key stems are slightly out of parallel so that the axes of the key stems meet in a direction of stroke relative to the key cap. However, the sleeves, into which the key stems insert, are parallel. When the key cap is pressed off-center, causing tilting of the key cap, one key stem advances ahead of the other. Because of the relative positions of the axes, binding forces increase in the leading key stem and decrease in the following stem. The asymmetry of the binding forces tends to correct the tilting of the key cap so that the key cap advances symmetrically and smoothly.

  • Patent number: 5437888
    Abstract: A waterproof zip closure is formed by extruding a first thermoplastic material onto its teeth, and applying a transverse force while the first thermoplastic material cures. The transverse force is sufficient to move the teeth in the separating direction, but is less than that which can cause separation. After curing of the thermoplastic material, the tapes and teeth of the zip closure are coated with a second thermoplastic sealing material, while the transverse force is maintained. When the transverse force is removed the sealing material is forced together to provide a waterproof seal. The second thermoplastic sealing material on the tapes further improves the waterproof nature of the zip closure.
