摘要： In a fluidized granulator made of steel sheet in accordance with the prior art, powder having high hygroscopicity is likely to cause blocking. Furthermore clogging is likely to occur in a bag filter. According to the present invention the outer walls of the granulator are made of a porous film in place of steel sheet of the conventional apparatus to eliminate the problems described above. This fluidized granulator can produce granules or coated powder particles by spraying water, a binder solution or a coating solution while powder is kept in a fluidized state.

摘要： A recording/reproducing head has a slider (2) in which an electromagnetic transducer (or an optical module) (1) is provided, an actuator (4) and a suspension (3). The actuator has a fixed part (43) and a movable part (44) and at least (2) beam parts with which the movable part (44) is connected to the fixed part (43). The beam parts have displacement producing parts (41) which are expanded/contracted by an inverse piezoelectric effect or an electrostriction effect. The fixed part (43) is connected to the suspension (3) and the movable part (44) is fixed to the slider (2). If the displacement producing parts (41) are expanded/contracted, the displacement producing parts (41) are deflected and the linear displacement, arc-form displacement or rotary displacement of the movable part (44) is produced relatively to the fixed part (43) and, further, the electromagnetic transducer (1) is displaced to describe a linear or arc-form path which crosses recording tracks. The actuator (4) consists of a plate-shape unit which is made of piezoelectric or electrostrictive material and has a hole part and/or a cut part to form the fixed part (43), the movable part (44) and the beam parts integrally. If the summation of driving voltages applied to the respective displacement producing parts is so controlled as to be constant at any time when the positioning in a direction crossing the recording tracks is carried out by using the actuator having the construction shown in the figure, the position fluctuation of the electromagnetic transducer in a direction perpendicular to the surface of a recording medium can be suppressed.

摘要： A surface acoustic wave device having interdigital type electrodes on the surface of a substrate composed of a single crystal of langasite belonging to a point group (32). The substrate is given a small absolute value of SAW speed temperature coefficient TCV, a large electromechanical coupling coefficient k , and a slow SAW speed by optimizing the combination of the cutting angle of the substrate from the single crystal and the surface acoustic wave propagating direction. Therefore, the temperature stability of the device can be improved and the passing bandwidth of the device as a filter can be widened. In addition, the size of the device can be reduced and, especially, excellent characteristics as the surface acoustic wave film for intermediate frequencies of mobile communication terminal equipment can be obtained.

摘要： A slurry containing ferrite particles and an organic solvent is wet molded in a magnetic field while removing the organic solvent, to obtain a molded article. This molded article is sintered to provide an anisotropic ferrite magnet. In this case, a surfactant is added to the slurry during wet molding. In addition to the surfactant or in place thereof, the ferrite particles are pulverized so as to impart at least 1 x 10 of strain of a (206) plane measured by X-ray diffraction, and to reduce iHc preferably below 3.5 kOe. In these ways, orientation of the molded article can be drastically improved, and extremely high magnetic characteristics can be obtained.
