Patent JP-S61248700-A (JP)
Title: Ultrasonic probe
Inventor: MIYAJIMA TAKESHI
IPC: H04R17/00
Filed: 1985-04-26
Abstract: PURPOSE:To allow an oscillator to possess together both characteristics of a wide frequency band area and high sensitivity by changing the shape of the oscillator which converts alternately an electric oscillation and an ultrasonic wave to the shape having thickness of integer-fold of 1/2 of the wave-length of a switched ultrasonic wave and outputting simultaneously a frequency component having each thickness. CONSTITUTION:The thickness of the oscillator 1 is shaped to be changed in order to different thickness of the integer-fold of 1/2 wave-length that is formed like a step at its back face and the back face is held with a damper 2 that is made of a material such as bakelite, epoxy resin, etc. A contact plug 4 and the oscillator 1 which are mounted at one end part of a metalic case 3 are connected electrically through an electrode 5 mounted on the back face of the oscillator 1 and the oscillator 1 and the case 3 are connected electrically through an electrode 6. When an electric pulse is given to the oscillator 1 from an ultrasonic flow inspector through the contact plug, at the oscillator 1, different resonating states are created according to different thickness of step-shape and simultaneously ultrasonic waves having frequency components corresponded with the resonance and a wide frequency band area is generated. On the other hand, the high sensitivity is maintained as it is by leaving the performance of the damper to be a low damping.

Abstract: PURPOSE:To make it possible to exchange tools without the necessity of an expensive ATC, by positionally controlling a tool bed in both X- and Z-axial directions to exchange a tool at an indexing position in a magazine with a tool at an exchanging position on a turret. CONSTITUTION:After completion of machining, an NC device delivers an instruction signal for retracting a tool bed 4 in the X-axis direction, and simultaneously, a saddle 2 also slides in the Z-axis direction to locate a turret at a turning position in order to index a rotary shaft 6 to a tool exchanging position. Meanwhile in a tool magazine device 11 an empty gripper device 14 is indexed to the tool exchanging position, and a tool holder 7 is located on the X-axis of a gripper grip section in association with the movement of the turret in both X- and Z-axial directions so that the tool holder 7 is gripped and is moved in the Z-axial direction. Accordingly, the tool holder 7 is pulled out from the turret 5 and is stored in the tool magazine device 11. Thereafter with the similar step in the reverse order, a required holder is loaded on the turret 5. With this arrangement, it is possible to enhance the working efficiency without the necessity of an expensive ATC.
