摘要： A vibrator has a large strength of a standing wave even with a low driving voltage, thereby improving the accuracy of component separation. A device according to the present invention includes a substrate having a channel groove provided in an upper surface of the substrate, a seal provided above the substrate so as to cover an upper opening of the channel groove, a projection provided on an outer side wall opposite to the channel groove, and a vibrator causing the projection to warp and vibrate in a depth direction of the channel groove. The warping vibration of the projection is amplified due to effect of leverage, and generates a large stress on the outer wall of the channel groove having the projection provided thereon. Consequently, the strength of a standing wave in the channel groove increases even for a low driving voltage, thereby improving the accuracy of component separation.

摘要翻译： 振动器即使具有低驱动电压也具有大的驻波强度，从而提高了元件分离的精度。 根据本发明的装置包括：衬底，其具有设置在衬底的上表面中的沟槽;密封件，设置在衬底上方以覆盖通道槽的上开口;突出部，设置在相对的外侧壁上 并且使振动器沿着沟槽的深度方向翘曲而振动。 突起的翘曲振动由于杠杆作用而被放大，并且在其上设置有突起的通道槽的外壁上产生大的应力。 因此，即使对于低驱动电压，通道槽中驻波的强度也增加，从而提高部件分离的精度。

摘要： A cellular electrophysiological measurement device includes a thin plate and a frame. The thin plate has a first surface with a depression and a second surface with a through-hole. The frame is in contact with an outer periphery on the second surface of thin plate. The thin plate has a laminated structure of at least two layers including a first material layer on the first surface and a second material layer on the second surface. The frame is formed of a third material layer. The structure allows the cellular electrophysiological measurement device to be not so vulnerable to breakage of thin plate and other damages, thereby having high production yield.

摘要： The present invention provides a kit employed for polymerase chain reaction. The kit has a cavity and a flow channel on a substrate. The flow channel is separated from the cavity by at least a barrier formed along the cavity. Such a structure allows the cavity to be filled with a sample solution even in minute quantities. At the same time, the structure can provide a sample solution with a rapid temperature-control. The structure can therefore contribute to accelerated polymerase chain reaction.

The angular velocity sensor comprises a vibrator, and a tuning-fork as the vibrator is formed of a silicone substrate with crystal orientation (100) as its main face, and a side face nearly perpendicular to the driving direction (X direction) of the arm of the tuning-fork corresponds to a crystal orientation where the elastic modulus is less dependent on azimuth angle.
