    摘要： An ultrasonic diagnosis apparatus for raising tissue temperature for hypothermic treatments, including an ultrasonic source for generating an ultrasonic treatment wave and a driving means for driving the ultrasonic source such that a frequency of the ultrasonic treatment wave generated by the ultrasonic source changes with time. The frequency of the ultrasonic treatment wave is changed along the time axis. By this change in frequency, some bubbles formed by cavitation as a result of the ultrasonic treatment wave are divided, and some bubbles are collapsed and therefore eliminated. Side effect cavitation and spread of a thermal degeneration area is suppressed, and thermal degeneration can be accurately induced in a desired area, thereby realizing a reliable, safe ultrasonic thermotherapy. Since cavitation is positively suppressed, the total treatment period can be shortened because cavitation would otherwise interfere with and slow down the thermal degeneration process. Therefore, treatment throughput can be improved as compared with a case in which cavitation is left to naturally break and disappear.

    摘要翻译： 一种用于提高低温治疗的组织温度的超声波诊断装置，包括用于产生超声波处理波的超声波源和用于驱动超声波源的驱动装置，使得由超声波源产生的超声波处理波的频率随时间而变化。 超声波处理波的频率沿时间轴变化。 通过这种频率变化，由于超声波处理波而产生的由空穴形成的一些气泡被分割，并且一些气泡被折叠并因此被消除。 抑制热变性区域的副作用空化和扩散，可以在期望的区域中精确地诱导热变性，从而实现可靠，安全的超声波热疗。 由于气穴被积极地抑制，所以总处理时间可以缩短，因为空化会妨碍和减慢热变性过程。 因此，与空穴自然断裂和消失的情况相比，能够提高处理量。

    摘要： An ultrasonic diagnosing system includes a probe having an vibrator made of a plurality of spaced piezoelectric; material elements arranged in a matrix, first electrodes arranged on one surface of the vibrator in an array of rows parallel to each other, and second electrodes arranged on another surface of the vibrator in an array of rows parallel to each other and orthogonally to the first electrodes.Particularly, the piezoelectric material elements are spaced by spacer segments arranged between the electrode rows and formed from a high molecular weight material with less acoustic impedance than the piezoelectric material, a Shore hardness D50 or more (JIS) and a thickness of about 1/10 to 1/2 of the piezoelectric elements. The ultrasonic diagnosing system uses a phased array technique to provide tomograms at mutually orthogonal and spatially close positions with sufficient sensitivity.

    摘要： A driving circuit controls a time for applying a drive signal to a piezoelectric element so as to bring a control in the number of ink droplets squirted from a liquid surface of liquid ink according to a gray scale level of an image to be printed on a printed object. According to application of the drive signal, acoustic waves emitted from a piezoelectric element array are focused in a main scanning direction, made incident to an acoustic lens via an acoustic matching layer, further focused in a direction orthogonal to the main scanning direction and focused in a vicinity of the liquid surface in a point form. In the vicinity of the liquid surface, an ink liquid mound is formed by means of pressure (discharging pressure) generated by the focused acoustic waves and then from a tip of the ink liquid mound an ink droplet according to the application time is squirted. The squirted ink droplet is ejected and stuck to the printed object. By performing main and subscanning to the printed object, a two-dimensional image is printed thereon.
