    • PROBLEM TO BE SOLVED: To provide a displacement enlarging device that meets a demand for space saving and further can reliably accomplish an increase in the amount of displacement in a slightly displacing device based on displacement in a slightly displacing actuator, with a necessary and sufficient displacement enlargement ratio. SOLUTION: The displacement enlarging device 13 comprises a long plate body 13a so formed that it is substantially identical with a laminated piezoelectric element in length and width. A supporting point 17 supported on the fixed end of the laminated piezoelectric element is provided at one end of the plate body 13a; a power point 18 supported on the free end of the laminated piezoelectric element is provided at the other end of the plate body 13a. A working point 19 is provided at the center of the upper side and that of the lower side of the plate body 13a. Therefore, when the laminated piezoelectric element is elongated under an applied voltage, the working point 19 is caused to displace in the direction orthogonal to the direction of the length of the laminated piezoelectric element by the action of a link mechanism of honeycomb-like periodic structure formed in the plate body 13a with a large displacement enlargement ratio.

    • 要解决的问题:提供一种满足空间节省需求的位移放大装置,并且还可以基于稍微位移的致动器中的位移可靠地实现稍微位移装置中的位移量的增加,具有必要 和足够的位移扩大比。 解决方案:位移放大装置13包括长板体13a,其形成为与层叠压电元件的长度和宽度基本相同。 支撑在层叠压电元件的固定端上的支撑点17设置在板体13a的一端; 支撑在层叠压电元件的自由端上的功率点18设置在板体13a的另一端。 工作点19设置在板体13a的上侧的中心和下侧的中心。 因此,当层叠压电元件在施加的电压下伸长时,通过蜂窝状周期性结构的连杆机构的作用使工作点19在与层叠的压电元件的长度方向正交的方向上移位 形成在板体13a中,位移增大比大。 版权所有(C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a drip infusion monitoring device and drip infusion monitoring system, capable of accurately detecting liquid drips even when the liquid drips are small, an infusion solution is close to transparency, or a drip infusion cylinder is inclined by the movement of a patient.SOLUTION: The drip infusion monitoring device detects the liquid drips falling inside a light transmissive drip infusion cylinder and calculates the number and interval of the falling drips. The monitoring device includes: a light emitting element and a light receiving element, which are arranged on the same side surface of the drip infusion cylinder; an amplification circuit for amplifying a signal from the light receiving element; a rectifying circuit for rectifying the amplified signal; a central calculation circuit for calculating the signal; a display means for displaying the calculation result; an alarm means for issuing alarm in response to the calculation result; and an interface for connecting the central calculation circuit to a host system. Thus, even when the liquid drips are small, the infusion solution is close to transparency, or the drip infusion cylinder is inclined by the movement of the patient, the liquid drips are accurately detected.
    • 要解决的问题:为了提供滴注监测装置和滴注监测系统,即使当液滴小时,也能够精确地检测液滴,输液溶液接近透明度,或滴注液体倾斜 通过病人的动作。

      解决方案:滴注监测装置检测落在透光滴注瓶内的液滴,并计算滴落数量和间隔。 监测装置包括:发光元件和光接收元件,其布置在滴注缸的同一侧表面上; 放大电路,用于放大来自光接收元件的信号; 用于整流放大信号的整流电路; 用于计算信号的中央计算电路; 用于显示计算结果的显示装置; 响应于计算结果发出报警的报警装置; 以及用于将中央计算电路连接到主机系统的接口。 因此,即使液滴小,输液也接近透明性,也可以通过患者的移动使滴注液体倾斜,能够精确地检测液滴。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a displacement measuring sensor and a displacement measuring system for highly sensitively measuring the displacement. SOLUTION: A piezoelectric film structure 10, composed of projection-shaped parts 101 and recessed parts 102 formed by inverting the same shape, is formed by processing a piezoelectric film made of a flat material. Long sides of the respective projection-shaped part 101 and recessed part 102 are cyclically connected with each other via flat strip-shaped parts respectively. Further, the projection-shaped part 101 and the recessed part 102 are connected with each other in such a way that slopes of the same inclination face each other by the strip-shaped part with displacement of half a cycle. In this way, the displacement is measured by measuring the signal voltage output from the piezoelectric film structure 10 tucked in such a way as to generate a negative Poisson's ratio.

    • 要解决的问题:提供用于高灵敏度地测量位移的位移测量传感器和位移测量系统。 解决方案:通过处理由平坦材料制成的压电膜,形成由突起形部分101和通过反转相同形状形成的凹陷部分102组成的压电膜结构10。 各个突出部101和凹部102的长边分别经由平板状部件循环连接。 此外,突起形状部分101和凹陷部分102以这样的方式相互连接,使得相同倾斜的斜面通过位移为半个周期的带状部分彼此面对。 以这种方式,通过测量从压电膜结构10输出的信号电压,以产生负的泊松比来测量位移。 版权所有(C)2010,JPO&INPIT
