    • Disclosed is a welding inspection method which does not require the inspector to be highly skilled, does not require waiting for the spot welded part to cool off, and with which the probe is not consumed or damaged. A probe temporarily mounted close to the welded part on the surface of a metal plate emits ultrasonic waves from an oblique direction with respect to the boundary surfaces between a plurality of metal plates. At this time, the probe is temporarily mounted at the position where the incident ultrasonic waves pass through the welded part at the boundary between the plurality of metal plates in an oblique direction with respect to the boundary surface. Also, a display processing means displays the intensity of the refrected ultrasonic waves. Alternatively, the display processing means displays the details of the detection result estimated based on the intensity of the reflected ultrasonic waves.

    • The present invention aims to stabilize sound-electricity conversion characteristics of a diaphragm-type sound-electricity conversion device as well as to decrease the noise level of an ultrasonic diagnostic apparatus using the sound-electricity conversion device. The sound-electricity conversion device is configured by a capacitor cell including a lower electrode formed on a silicon substrate and an upper electrode over the lower electrode, the lower and upper electrodes sandwiching a cavity. An electrode short-circuit prevention film is formed on the upper electrode on the cavity side. The electrode short-circuit prevention film is formed of a material with an electrical time constant shorter than 1 second and longer than 10 microseconds, such as silicon nitride containing a stoichiometrically excessive amount of silicon. As a result, the electrode short-circuit prevention film has small electric conductivity, and thus it is made possible to prevent the film from being charged with electric charge and to avoid the drift of the electric charge. Consequently, the sound-electricity conversion characteristics of the sound-electricity conversion device stabilize, and further the sound noise level of the ultrasonic diagnostic apparatus decreases.
    • 本发明旨在稳定隔膜式声电转换装置的声电转换特性,并且降低使用声电转换装置的超声波诊断装置的噪声水平。 声电转换装置由包括形成在硅基板上的下电极和下电极上的上电极的电容器单元构成,下电极和上电极夹着空腔。 在空腔侧的上部电极上形成电极短路防止膜。 电极短路防止膜由电气时间常数短于1秒且长于10微秒的材料形成,例如含有化学计量过量的硅的氮化硅。 结果,电极短路防止膜具有小的导电性,因此可以防止膜被充电并避免电荷的漂移。 因此,声电转换装置的声电转换特性稳定,超声波诊断装置的声音噪声水平进一步降低。

    • In a disk array apparatus, by taking note of a first sound of a specific frequency which is a noise element of original sounds generated from a fan, a second sound whose phase is inverted to that of the first sound is generated by a structure of a cooling air flow path passing through the fan, and the second sound is synthesized with the first sound on the cooling air flow path, thereby reducing the noise. For example, an exhaust duct is located on a fan unit in an upper part of the apparatus, two flow paths extending to an exhaust port are formed in an internal structure of the exhaust duct, and the two flow paths are designed so that the difference in the flow path length therebetween becomes equivalent to half wavelength of the specific frequency.
