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.

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.

A method and a structure for joining members are provided which are suited for reinforcement of a shape.An auxiliary member 7 is inserted into respective holes 9a and 9b of first and second portions 8a and 8b of a main member 6 such that tip and base ends of the auxiliary member 7 are in the holes 9b and 9a of the second and first portions 8b and 8a, respectively. A joining tool 5 is pushed, while rotated, on the tip end of the auxiliary member 7 to soften the portion of the auxiliary member and the second portion 8b of the main member 6 due to frictional heat and plastic flow. Then, the joining tool 5 is released from the main member 6 to allow the second portion 8b and the plastic flow portion of the auxiliary member 7 to solidify. Further, the joining tool 5 is pushed, while rotated, on the base end of the auxiliary member 7 to soften the portion of the auxiliary member and the first portion 8a of the main member 6 due to frictional heat and plastic flow. Then, the joining tool 5 is released from the main member 6 to allow the first portion 8a and the plastic flow portion of the auxiliary member 7 to solidfy.

摘要:
The receive sensitivity of an ultrasound array transducer structured with a diaphragm electro-acoustic transducer (101) being a basic unit is affected by change in a charge amount with elapsed time due to leakage or the like, which causes drift of the primary beam sensitivity, degradation in the acoustic SN ratio due to a rise in the acoustic noise level, and degradation in the directivity of an ultrasound beam. To addressing this problem, a charge controller (charge monitor 211) is provided to control charge in an electro-acoustic transducer (101). A charge monitoring section (102) monitors the change in the charge amount. When change in the charge amount is small, transmit sensitivity or receive sensitivity is calibrated by a controller (104) by, for example, multiplying a receive signal by a calibration coefficient corresponding to the change amount. Further, when the change in the charge amount is large, for example, charges can be re-emitted from a charge emitter (103). The series of operations is controlled by the controller (104), and thus sensitivity variation caused by difference in the changes with elapsed time, particularly between the plural transducers, is calibrated.
