摘要： A key structure includes a top plate which is formed by laminating a half-transparent resin surface layer member on a resin bottom side member using two-color injection molding, and the top plate is secured on a wooden key base. A plurality of concave grooves and protrusions, and a plurality of protrusion and troughs are respectively formed together in straight lines in the long direction of the key structure on a rear face of the surface layer member and a top face of the rear side member. Outside light is reflected from the top ends of the protrusion and the troughs, whereby a faint and natural vertically-striped pattern, which corresponds to a concave-convex part formed by the concave grooves and the protrusions, is perceived as resembling an edge grain of ivory.

摘要： A family of composite materials consisting of a mineral filler and a synthetic polymer are provided which are characterized by properties similar to natural ivory. The ivory-like composite material contains about 25 to about 75 percent by weight of the mineral filler, preferably a calcium phosphate. In addition, the composite material contains about 75 to about 25 percent by weight of the polyamino acid, preferably an .alpha.-amino acid such as poly(gamma-methyl L-glutamate). The composite material is formed using in situ polymerization techniques, thereby ensuring intimate and homogeneous blending of the mineral and polymer phases as well as facile preparation at ambient temperatures. In addition, the ivory-like composite material is molded using an isostatic compression molding technique. The composite material may be molded to form virtually any desired shape for decorative or practical purposes, or for subsequent carving. The resulting ivory-like composite materials are characterized by properties similar to natural ivory.
摘要翻译：提供由矿物填料和合成聚合物组成的复合材料族，其特征在于类似于天然象牙的性质。象牙状复合材料含有约25至约75重量％的矿物填料，优选磷酸钙。此外，复合材料包含约75至约25重量％的聚氨基酸，优选α-氨基酸，例如聚（γ-甲基L-谷氨酸）。使用原位聚合技术形成复合材料，从而确保矿物和聚合物相的均匀和均匀共混以及在环境温度下的容易制备。此外，象牙状复合材料使用等静压压模技术成型。复合材料可以被模制以形成用于装饰或实际目的的几乎任何所需的形状，或用于随后的雕刻。得到的象牙复合材料的特征是类似于天然象牙的性质。

摘要： A key cover plate for a piano or the like is injection-molded thermoplastic material marbleized by incomplete mixing of a color agent. The cover plate simulates the grain of natural ivory and has a Munsell hue of between 4.5Y to 8.8Y to 6.6YR. The cover plate also has a Munsell chroma of between 1.0 to 2.6 and a Munsell value of between 8.3 to 9.3. A contrast ratio of the plastic ivory material is between 70 to 90.

摘要： Button rods are made of different colored resins containing thixotropic agents and having catalyst and promoter agents added to separated portions of each resin so that when the resins are combined their gel time is accelerated. The combined resins are mixed both for mixing purposes and to lower the apparent viscosity, and the resins are fed through nozzles and into an inclined trough. The nozzles are reciprocated in arcs to lay the resins in a zig zag pattern in the trough, and the resins flow from the trough into an inclined casting tube where they quickly attain a relatively high apparent viscosity until they are removed from the tube before completely hard. The rods can then be sliced into button blanks or hardened and ground into beads.
摘要翻译：按钮杆由含有触变剂的不同着色树脂制成，并且在每个树脂的分离部分中加入催化剂和促进剂，使得当树脂组合时，它们的凝胶时间被加速。将混合的树脂混合以用于混合目的并降低表观粘度，并且树脂通过喷嘴进料并进入倾斜槽。喷嘴在圆弧中往复运动以将树脂在槽中以锯齿形图案放置，并且树脂从槽流入倾斜的铸管，在那里它们快速获得相对高的表观粘度，直到它们在完全硬化之前从管中移除。然后将棒切成纽扣坯料或硬化并研磨成珠。

摘要： A piano key cover having a body of synthetic material pigmented to resemble natural ivory defines a top playing surface having a random orientation of peak-to-valley texture and a multiplicity of fine pores to replicate a surface of natural ivory. A multiplicity of the pores have diameters generally in the range of 0.0002 to 0.0012 inch (0.005 to 0.030 mm). The synthetic material is selected from the group consisting of acrylic polymer, polyurethane, epoxy and the like. A method for forming such a piano key cover and a piano having key covers of the invention are also described.
