    • A speech piece editing section (5) retrieves speech piece data on a speech piece the read of which matches that of a speech piece in a fixed message from a speech piece database (7) and converts the speech piece so as to match the speed specified by utterance speed data. The speech piece editing section (5) predicts the prosody of a fixed message and selects an item of the retrieved speech piece data most matching each speech piece of the fixed message one by one according to the prosody prediction results. However, if the proportion of the speech piece corresponding to the selected item of the speech piece data does not reach a predetermined value, the selection is cancelled. Concerning the speech piece for which selection is not made, waveform data representing the waveform of each unit speech is supplied to a sound processing section (41). The selected speech piece data and the supplied waveform data are interconnected thereby to create data representing a synthesized speech. Thus, a speech synthesis device for quickly producing a synthesized speech without any uncomfortable feeling with a simple structure is provided.
    • 语音片编辑部(5)从语音片数据库(7)检索与固定消息中的语音片段相匹配的语音片段上的语音片段数据,并将语音片段转换为与指定的速度相匹配 通过话音速度数据。 语音片编辑部(5)预测固定消息的韵律,并根据韵律预测结果逐个选择最匹配固定消息的每个语音片段的检索到的语音片段数据的项目。 然而,如果对应于语音片数据的所选项目的语音片段的比例未达到预定值,则该选择被取消。 关于不进行选择的语音片段,表示每个单位语音的波形的波形数据被提供给声音处理部分(41)。 所选择的语音片段数据和所提供的波形数据被互连,从而产生表示合成语音的数据。 因此,提供了一种用于以简单的结构快速产生合成语音而没有任何不适感的语音合成装置。

    • An inverting negative voltage DC-DC power supply circuit comprises a first resistor having one end connected to an output terminal for converting a change in output voltage into a current. A zero-volt clamp circuit is connected to the other end of the first resistor and comprises a first and second transistor. A current mirror circuit comprises a third and fourth transistor and is connected to the zero-volt clamp circuit for causing a current of the same value as that of a current flowing in the zero-volt clamp circuit to flow. A second resistor is connected to the current mirror circuit for converting a change in current flowing from the zero-volt clamp circuit into a voltage.

    • A method to check a tissue located in the vicinity of an object of examination when a treatment instrument such as a puncture needle is inserted into a subject, wherein a first planar image construction block included in an image construction unit reconstructs in real time two-dimensional planar images, which represent subject's slice planes, on the basis of projection data. A stereoscopic image construction block included in the image construction unit constructs three-dimensional stereoscopic images, which represent the subject's slice planes, on the basis of projection data. The planar images constructed by the first planar image construction block are displayed in real time on the screen of a display unit, and the stereoscopic images constructed by the stereoscopic image construction block are displayed on the screen of the display unit while being juxtaposed with the first planar images constructed by the first planar image construction block.
