Abstract: PURPOSE:To judge the presence of the deteriorated layer in the surface of a processed article according to a non-destructive measuring method by calculating the propagation speed of the surface elastic wave of a sample from the cycle calculated by measuring receiving signal voltage while the distance of an acoustic lens in the axial line direction thereof is changed. CONSTITUTION:The sonic wave (b) incident to a sample 5 at an angle theta is converted to a surface elastic wave which in turn propagates through the surface of the sample 5 while leaks and passes through an acoustic lens 3 along a route symmetric to the incident wave to reach a piezoelectric film 2.

The sample 5 is fixed and the lens 3 is moved on a Z-axis to investigate the change of the receiving signal voltage and the cycle thereof is calculated. When the propagation speed of the surface elastic wave is calculated from said cycle, the deteriorated layer in the surface of a processed article can be judged according to a non-destructive method and an efficient cutting condition can be selected within a range generating no lowering of strength.

Inventor: KITO SHOZO
IPC: E05B29/02
Filed: 1993-12-22
Abstract: PURPOSE:To provide a cylinder lock device that is able to keep off any illegal unlocking as well as to prevent the constituent parts from being damaged, and besides, to provide relatively ease of axial dimensional control over these parts. CONSTITUTION:In the case where a key other than the regular key and a driver or the like are inserted thereinto and rotatively operated, notched recesses of each tumbler 28 will in no case come to a state of being aligned, therefore a movable bar 35 is prevented from shifting in the rear and is not engaged with a rear rotor 42. In consequence, a key rotor 22 merely runs idle together with the movable bar 35, so no excessive force acts on those of constituent parts of the tumblers 28 or the like, and thereby they are protected from being damaged. Since a cam part 41 guiding movements of the movable bar 35 is installed in a rotor case 21, the key rotor 22 and this rotor case 21 are related to the axial dimensional accuracy of this movable bar 35 to some extent, but the rear rotor 42 is not directly related to it.
