摘要： A device is disclosed which has a solid interior and at least one surface which is porous. The porous surface has several desired characteristics, including: (1) the majority of pores have dimensions within a size range that encourages the migration of cells into said pores, such as about 50 to about 500 micron diameters, and (2) the pores have a controlled depth, such as about 300 microns or less. Such devices may be created by several methods, such as injecting casting material into a mold which is fitted with a shell of porous material having the desired shape and characteristics. Such devices are useful as artificial teeth and orthopedic appliances.

摘要： This invention relates to the formation of a new solid material composed of calcium phosphates and to the reaction method for producing this material. The solid calcium phosphate material is created by chemically reacting calcium ion sources with phosphate ion sources in a molten state and cooling the reaction mixture to room temperature producing the solid material. Depending upon the ratio of components and the parameters of the heating reaction, the resulting material may be a smooth, non-porous material with exceptional hardness, or it may be a porous material. Both types of material can be shaped into desired configurations, such as artificial teeth.
摘要翻译：本发明涉及由磷酸钙组成的新固体材料的形成及其制备方法。固体磷酸钙材料是通过使钙离子源与熔融状态的磷酸根离子源化学反应并将反应混合物冷却至室温产生固体物质而产生的。取决于组分的比例和加热反应的参数，所得到的材料可以是具有优异硬度的光滑，无孔的材料，或者它可以是多孔材料。两种类型的材料可以被成形为所需的构造，例如人造牙齿。

摘要： A safety vehicle (10) for passengers includes a horizontally disposed chassis (16) having a front (16a) and rear (16b) portion. The vehicle body (14) is disposed on the chassis (16) and includes a passenger section (20) disposed intermediate the front and rear portions of the chassis (16). The chassis (16) includes three lever arms (44, 46, 48) pivotally interconnected. The first lever arm (44) is disposed adjacent the front portion of the chassis (16). A second lever arm (48) is disposed adjacent the passenger section (20). The third lever arm (46) is pivotally interconnected to the first and second lever arms, such that the first end of the third lever arm is pivotally connected adjacent to the second end of the first lever arm (44) at a first pivot point (60). The second end of the third lever arm (46) is pivotally connected adjacent to the first end of the second lever arm (48) at a second pivot point (62). Upon impact, the chassis (16) front portion (16a) rotates about the first pivot point (60) in a first direction of rotation (68) and the chassis rear portion (16b) rotates about the second pivot point (62) in a second direction of rotation (70) opposite to the first direction of rotation (68) of the chassis front portion (16a) thereby removing the passenger section (20) from the linear impact forces created by the collision and translating a portion of the linear deceleration motion of the vehicle (10) into rotational motion of the passenger section (20).
