  • Patent number: 6959614
    Abstract: An apparatus for controlling the movement of a specimen in order to handle the specimen, e.g., a cell, easily and quickly with high accuracy. A standing wave vibration (V) having at least one node (N1, N2) is generated in a vibrator (11). A specimen in a medium (30) is captured at a position in the vicinity of the surface of the node (N1, N2) and then turned in this position. The capturing position of the specimen (S) is altered through variable control of the vibration mode of the standing wave vibration (V), and the moving route, moving speed, or rotational speed of the specimen (S) is controlled as desired through variable control of the vibration parameters (e.g., frequency, amplitude, intermittent frequency) of the standing wave vibration (V).

  • Patent number: 6807861
    Abstract: A noncontact physical property measurement instrument which easily and accurately measures physical properties of an object using a nondestructive, noncontact sensor. A noncontact physical property measurement instrument 1 is provided with a transmitting section 21 and a receiving section 22. The transmitting section 21 sends a wave to an object 41 in a medium 100, and the receiving section 22 receives a wave reflected from the object 41 and the surface of a coating 42. Both the transmitting section 21 and the receiving section 22 are connected to a gain change correction circuit 13 to form a self-excited oscillating circuit 11 serving as a feedback loop. The gain change correction circuit 13 corrects the gain to the increase side according to a phase difference between the sent wave and the reflected wave, to thereby measure any changes due to a difference in physical properties of the object 41.
