METHOD OF CONTROLLING REGULATING HOLE |
摘要 |
<p>A method of controlling a regulating hole for regulating an amount of light, a flow rate of fluid, a pressure of fluid passing through a tubular passage is provided. A partition wall 5 formed by a viscoelastic solid containing magnetic particles is transversely disposed in the tubular passage 3 through which light or fluid passes. The partition wall 5 is provided with a regulating hole 6 for regulating an amount of the light, a flow rate of the fluid, or a pressure of the fluid so that the regulating hole 6 penetrates in an axial direction. Magnetic field gradient is generated the partition wall 5 in a radial direction in the tubular passage 3 to thereby change an opening degree of the regulating hole 6.</p> |
