    • PROBLEM TO BE SOLVED: To provide a syringe assembly providing storage of multi-component substances and easy mixing of the multi-component substance prior to its application and reducing the loss of the discharged substance.
      SOLUTION: This syringe assembly 1 is provided with a syringe body member 2 forming a syringe barrel having a syringe passage 3 extending over the length of the syringe barrel; a discharge port 4 smaller in diameter than the syringe passage and communicating with the syringe passage and its front end 5; and at least one piston member 6 located in the syringe barrel to divide the syringe passage into at least a first chamber 7 at the front end of the syringe passage and a second chamber 8 at the rear end 9 of the syringe passage, and provided with a piston rod 10 for actuating the piston member 6. At least one piston member is constituted to provide fluid connection between the chambers.

    • PROBLEM TO BE SOLVED: To provide a device for producing a dental workpiece, machining a blank more favorably.
      SOLUTION: The blank 13 is inserted in a substantially slab-shaped support body 10 of the device, and the support body is dimensioned such that the blank 13 does not extend beyond it in any direction. The blank 13 is linked with corresponding inner walls of a recess 12 provided in the support body 10 only on two opposite faces while a gap is left between the other inner walls of the recess 12 and the corresponding faces of the blank 13. Therefore, tensions and microcracks of the blank material caused thereby are allowed to be avoided. The gaps further make the blank 13 directly accessible for a lateral working by a milling tool.

    • 要解决的问题:为了提供一种用于制造牙科工件的装置,更有利地加工坯料。 解决方案:坯料13插入装置的基本上板状的支撑体10中,并且支撑体的尺寸被设计成使得坯件13不会在任何方向上延伸超过它。 坯件13仅在设置在支撑体10中的凹部12的相应内壁上,仅在两个相对的面上连接,同时在凹部12的其它内壁和坯料13的相应面之间留有间隙。因此,张力 并且允许避免由此引起的坯料的微裂纹。 间隙进一步使得坯料13可直接通过铣削工具进行横向加工。 版权所有(C)2007,JPO&INPIT
