摘要： A plurality of interdigital transducers (IDTs) of a surface acoustic wave bandpass filter, each of which has a plurality of electrode fingers arranged in a direction perpendicular to a propagating direction of surface acoustic wave, are connected alternatively to an input terminal and an output terminal of said filter. The IDTs are different in number of electrode fingers and in average value of inter-finger distance from each other and distance between adjacent IDTs are different. At least one of the outermost IDTs has a minimum number of electrode fingers and a maximum average value of inter-finger distance, compared with those of other IDTs.

摘要： A laser drive integrated circuit and an optical disk apparatus using the laser drive integrated circuit for forming high-density marks. The optical disk apparatus includes a drive waveform information storage unit for storing at least one information of a drive waveform for driving a laser diode in response to a binary recording signal to be recorded in a recording medium, and a drive waveform decoder for decoding the drive waveform based on the information stored in the drive waveform information storage unit. A recording strategy can be changed in accordance with variations and fluctuations of recording media or characteristics of the recording media, while at the same time reducing a number of signal lines in flexible wiring and alleviating effects of signal distortion in the signal lines.

摘要： A device for displacing and supporting a driven member pickup head in all the coordinate axis directions of three coordinate axes perpendicular to one another. The device includes at least one support member formed of viscoelastic material for supporting the driven member on a frame. The support member is tensioned and connected between the driven member and the frame and has one end affixed to the driven member disposed in a plane perpendicular to an arbitrarily selected one coordinate axis of the three coordinate axis directions and the other end affixed to the frame disposed in a plane perpendicular to the one coordinate axis. The pickup actuator also includes a device for generating lines of magnetic force in two directions perpendicular to each other, a first coil and a second coil secured to the driven member and having a first path of current and a second path of current respectively disposed in one direction of the magnetic lines of force and perpendicular to each other in a plane perpendicular to the one direction of the magnetic lines of force, a third coil secured to the driven member and having a third path of current disposed in the other direction of the lines of magnetic force and parallel to one of the first path of current and the second path of current in a plane perpendicular to the other direction of the lines of magnetic force, whereby the pickup holder can be independently driven for movement in three axis directions perpendicular to one another.
