摘要： An ultrasound medical treatment apparatus includes an ultrasound applicator for applying ultrasound irradiation to a treatment target. The treatment apparatus also includes an ultrasound imaging device that transmits ultrasound pulses to image the treatment target. The treatment apparatus is capable of reducing noises occurring at an ultrasound imaging device due to the ultrasound irradiation generated by the ultrasound application during ultrasound medical treatment. The noises may be reduced by increasing a transmission power of the ultrasound pulses. Alternatively, the noises may be reduced by subtracting pre-recorded noise components from the ultrasound pulses received by the ultrasound imaging device, where the pre-recorded noise components are characteristic of noise occurring at the ultrasound imaging device due to the ultrasound irradiation generated by the ultrasound applicator.

摘要： An ink jet recording apparatus uses supersonic waves focused on an ink holding container to inject ink from the ink surface onto a recording medium. A piezoelectric element driven by a first driving signal serves as the supersonic wave generator. The piezoelectric element can also be driven by a second driving signal to effectively circulate the ink in the holding container. The second driving signal results in an acoustic pressure at the ink surface lower than the acoustic pressure necessary for injecting the ink onto a recording medium.

摘要： A device for performing identification by sensing the fingerprint of a finger includes an input unit. The input unit is constituted by a plurality of linear contact electrodes formed on a substrate, and a pressure-sensitive sheet formed on the linear contact electrodes and a resistance thereof changes in accordance with a pressure applied thereto. When the finger touches the surface of the pressure-sensitive sheet, a change in resistance is caused between the electrodes, and this change is converted to data of a one-dimensional electrical signal distribution. The obtained data is compared with registered data, thereby performing identification. The time required for signal processing necessary in the identification device can be decreased.

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。
