Title: Ultrasonic processing device
Inventor: KUBOTA TETSUMARU
IPC: A61B17/22
Filed: 1988-10-05
Abstract: PURPOSE:To obtain an ultrasonic processing device having an ultrasonic wave transmitting member whose intermediate section has a welded part and having an excellent durability such that no breakage occurs even though a probe is subjected to repeated stress caused by ultrasonic vibration, by locating the welded part at a position other than the nodes of the ultrasonic vibration. CONSTITUTION:A probe 20 is composed of a first member 21 and a second member 22. Further, the rear surface of the second member 22 is welded to the front surface of the first member 21. When a voltage is applied to an ultrasonic vibrator 3, vibration is amplified by a horn 6 and is transmitted to the probe 20. Further, the flanks of the amplitudes of the vibration are located in the connection part between the first member 21 and the horn 6, the welded part 25 between the first and second members 21, 22 and the front end part of the second member 22 while the nodes are located at positions other than the connection part between the first member 21 and the horn 6 and the welded part 25 between the first and second members 21. With this arrangement, the probe 20 does not come off from the welded part 25 even though it is subjected to repeated stress, thereby it is possible to enhance the durability.

Title: Optical recording medium
Inventor: MUTO AKIRA
IPC: G11B7/24073
Filed: 1985-11-08
Abstract: PURPOSE:To prevent the recording bit width of an information signal from being made larger than required and to decrease crosstalks in the stage of reproduction by providing an unrecordable region between adjacent recording regions. CONSTITUTION:A photomagnetic recording film 2 is provided on a substrate 1 having guide grooves. The recording regions are provided to the projecting parts of the substrate 1 and the unrecordable regions are provided to the recesses thereof. Upward magnetization is applied to the recording regions and the magnetization opposite therefrom is applied to the unrecordable regions respectively before recording of the information signal. Modulated laser light is irradiated to the recording regions while the downward external magnetic field is applied to said regions after such treatment to induce the inversion of the magnetization by the external magnetic field in the part where the temp. rises to a certain degree or above. The recording bits are thereby formed and the information signal is recorded. On the other hand, the unrecordable regions have the magnetization in the same direction as the direction of the external magnetic field and the magnetization inversion does not arise in said region even if the temp. rises. The increase of the recording bit width to the size larger than required is thereby prevented and the crosstalks are decreased.
