    • PROBLEM TO BE SOLVED: To provide an extensible structure capable of forming a curved face.
      SOLUTION: The extensible structure 10 is formed by folding a sheet member 12 having a plurality of constitution units 14 arranged in longitudinal and lateral directions. When the extensible structure 10 is stretched in lateral direction, the angle between longitudinally adjacent constitution units 14 is changed to form a curved face having the curved circumference in longitudinal direction. When one end of the extensible structure 10 is fixed and the other end is moved in the direction of depth, the angle between the laterally adjacent constitution units 14 is changed to form a curved face of the extensible structure 10 having the curved circumference in lateral direction.

    • 要解决的问题:提供能够形成弯曲面的可延展结构。 解决方案:可延伸结构10通过折叠具有沿纵向和横向布置的多个构造单元14的片材构件12而形成。 当可伸展结构10沿横向拉伸时,纵向相邻构造单元14之间的角度被改变以形成在纵向上具有弯曲圆周的曲面。 当可延伸结构10的一端固定并且另一端沿深度方向移动时,横向相邻构造单元14之间的角度被改变以形成具有横向弯曲圆周的可延伸结构10的曲面 。 版权所有(C)2005,JPO&NCIPI

    • A vacuum pump includes rotary shafts connected to a pair of screw-type rotors, respectively, and a pair of shaft retainers extending in the housing. Each shaft retainer supports the corresponding rotary shaft by means of a proximal bearing portion and a distal bearing portion. Each pair of the proximal and distal bearing portions are fixed in the axial direction with respect to the corresponding rotary shaft and shaft retainer. Lubricant oil is stored in an oil storage space in a gear case attached to the housing. A cooling water passage through which cooling water to cool the lubricant oil passes is formed in the gear case. A controller controls the flow rate of the cooling fluid, so that the temperature of the lubricant oil in the oil storage space is kept constant. With this configuration, when the bearing portions are fixed in the axial direction with respect to the rotary shafts and the shaft retainers, it is possible to prevent load from being applied to the bearing portions in the axial direction.
    • 真空泵包括分别连接到一对螺杆式转子的旋转轴和在壳体中延伸的一对轴保持器。 每个轴保持器通过近侧轴承部分和远侧轴承部分支撑相应的旋转轴。 每对近端和远端轴承部分相对于相应的旋转轴和轴保持器沿轴向固定。 润滑油储存在附接到壳体的齿轮箱中的储油空间中。 在齿轮箱中形成有用于冷却润滑油的冷却水通过的冷却水通道。 控制器控制冷却流体的流量,使得储油空间中的润滑油的温度保持恒定。 利用这种构造,当轴承部分相对于旋转轴和轴保持器沿轴向方向固定时,可以防止在轴向方向上对轴承部分施加负载。
