摘要： PROBLEM TO BE SOLVED: To release biological tissue sucked to a suction port without inviting complication of a structure and control in a fluid jetting device which recovers jetted fluid by suction.SOLUTION: At least a part of a side face of a suction pipe is formed from an elastic member, and on the elastic member, a negative pressure release part to be opened when the elastic member is deformed by the negative pressure of the suction pipe to release the negative pressure inside the suction pipe is formed. In such a manner, when an object is sucked to the suction port, the negative pressure release part is opened by deformation of the elastic member caused by the negative pressure inside the suction pipe. Thus, since the negative pressure inside the suction pipe is released, the sucked object is separated from the suction port. Also, since the negative pressure release part is automatically opened when the object is sucked to the suction port, the need of performing control for opening and closing the negative pressure release part is eliminated. In addition, a pressure sensor or the like is not needed and the structure is not complicated.
摘要翻译：要解决的问题：释放吸入吸入口的生物组织，而不会引起在通过抽吸回收喷射流体的流体喷射装置中的结构和控制的复杂化。解决方案：吸入管的侧面的至少一部分由弹性构件形成，并且在弹性构件上，当弹性构件由于弹性构件的负压而变形时，打开的负压释放部抽吸管释放吸入管内部的负压形成。以这种方式，当物体被吸入吸入口时，通过吸入管内的负压引起的弹性部件的变形而使负压解除部分打开。因此，由于抽吸管内的负压被释放，所以被吸收物体与吸入口分离。此外，由于当物体被吸入吸入口时负压释放部分被自动打开，所以不需要进行打开和关闭负压释放部分的控制。此外，不需要压力传感器等，结构不复杂。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To easily deaden a driving sound generated by accompanying jetting of a liquid by a liquid jetting device.SOLUTION: The volume of a liquid chamber is reduced by applying a driving voltage to a part for reducing the volume of a liquid chamber while the liquid is supplied to the liquid chamber to jet the pressurized liquid in the liquid chamber from a jetting nozzle. In addition, a canceling sound is output to deaden the driving sound generated by the application of the driving voltage, and the canceling sound to be output is switched based on the driving voltage to be applied. In this way, if the driving sound varies because of the change in the driving voltage, the appropriate canceling sound is output based on the driving voltage after the change. Consequently, there is not need to sample the driving sound by a microphone, and the driving sound is easily deadened.
