Abstract

PURPOSE:To make it possible to perform the checking of unsealing and the discrimination of an individual by one measuring operation and to improve efficiency of measuring work, by forming defective parts on a path of an ultrasonic wave or its reflected wave from the individual to be discriminated, and measuring the disturbance in the reflected wave. CONSTITUTION:A part of the path of an ultrasonic wave or its reflected wave from a body 1, e.g., a central constricted part of the body 1, is made to be a welding part 2. Defect 3 are yielded by the welding. The ultrasonic wave is applied for checking unsealing. The unsealing check can be performed by the presence of the reflected wave from the bottom of the body 1. At the same time, the body 1 as an individual can be discriminated by discriminating the complicated waveform of the reflected wave, which is yielded by the disturbance of the reflected wave due to the defects 3. In order to enhance the accuracy of discrimination, two welding parts 2a and 2b and defective parts 3a and 3b are provided on the body 1 and the reflected waves can be measured. Even though the welding parts 2 and the defective parts 3 are provided at two places, the range of the defective parts 3 is expanded by making the thickness of the welding parts thick, and the sufficient individual discriminating ability can be obtained.

Figure 2 (Ino shows one embodiment of the present invention, object 1
A portion that is a path for the super-single wave or its reflected wave, for example a finned portion in the center of the object 1, is defined as a welded portion 2, and a defect 3r is generated by bath contact of this welded portion 2. By detecting the waves that exceed the waves for checking tampering, tampering can be checked due to the presence of reflected waves from the bottom of the object 1, and at the same time, sloppy reflected waveforms caused by disturbances in the reflected waves due to defect 3 can be identified. As a result, the individual identification of object 1 becomes n' possible.

■/This defect is not only caused by bathing, but also by other methods.
For example, it is good to form a hole by drilling 1 hole in 10 objects using an awl or the like. Defects caused by regularly formed holes on this jM scale are easily destroyed by the writing of the reflection wave, and in this respect, it is inferior to the case using bath contact, or it is easy to process the reflected waves before two-way processing. This changes the starting point that can contribute to the improvement of discrimination ability. However, the defect is caused by a method such as mixing it into an object that can be used in the X-rays (in the super-Okeba ruins or outside), to produce a similar effect to that of bathing or Kiri-dera. The ability to generate awn is h' ability.

In addition, in this example, the defect 3 was created in the central fin of the object 1, which is necessary in the path of the ultrasonic waves and also in the path of the reflected waves. Disturbances are common, and the path of the ultrasonic waves is often interrupted by a single stroke of the path of the reflected waves from the tenon.
It is sufficient to provide defect 3. Depending on the structure of the object 1, the defect 3 may be caused by either the path of the ultrasonic wave or the path of its repulsive wave. However, if JjlJ < in this example, if the defect 3 is provided in the center part of the object 1, the defect 3 will reflect the incident ultrasonic wave, causing disturbance of the reflected wave. ri rise. This means that even if the reflected wave from the plate (of the object) disappears when the package is opened, the reflected wave from defect 3 will return, so even if there is ↓ when the package is opened, it will be difficult to identify the individual
We have a meeting called ◇.
