摘要： This invention provides a surface elastic wave device constituted by a unitary body of a piezoelectric plate having a pair of transducers thereon, which unitary body is embedded in a casing, and wherein the wave propagation of a surface elastic wave generated on the surface of the piezoelectric plate during excitation of the device is prevented from being transferred to the casing by a thin film inserted between the casing and the wave propagation surface of the piezoelectric plate or by using as the casing a roll of flexible sheet which has the same function of wave propagation prevention as that of the thin film. This device is advantageous because it has a low spurious signal level without incrementing insertion loss, is easy to manufacture and is inexpensive. This invention also provides an effective method of making the device.

摘要： A damped piezoelectric ceramic resonator. The resonator is a thin flat plate of piezoelectric ceramic material which has parallel major planar surfaces and is polarized in one direction in such a way that said direction is at an angle of from 0.degree. to 60.degree. with respect to said major surfaces, the thickness dimension of said plate being such as to impart thereto a resonance of vibrations in a thickness-shear mode at a particularly selected frequency higher than one megacycle. Operating electrodes are applied to said major planar surfaces. Vibration damping means is attached tightly to the contour of the edge of said flat plate so as to suppress unwanted resonance vibrations in said flat plate during operating. The vibration damping means is a ring of a rubber material having a hardness from 20 to 70 on the Shore A Scale and is under a tension of 20-500 gm/cm.

摘要： A frequency discriminating apparatus is constituted by a piezoelectric ceramic resonator, a reference capacitor, a pre-amplifier including a broad tuning circuit, a pair of amplitude detectors, and a differential amplitude limiter. The piezoelectric ceramic resonator is made of a piezoelectric lead titanate ceramic plate having a pair of electrodes covering the entire area of the major surfaces thereof, and the plate is poled with a poling field of not less than 50 kV/cm in the thickness direction. The thickness of the plate is chosen so as to cause the plate to vibrate in the thickness-extensional vibration of the 3rd harmonic overtone at a preselected frequency when an electrical signal is applied to the pair of electrodes. The differential amplitude limiter differentially adds the two signals detected by the two amplitude detectors and limits the peak output voltage amplitudes to a predetermined amplitude. The center frequency for the frequency discrimination by this apparatus can be stably maintained according to this apparatus, and the apparatus can be easily manufactured in the form of integrated circuits without necessitating many value adjustments of circuit elements.

摘要： An ignition coil according to the invention is an ignition coil having a case and a coil portion accommodated in the case. The case comprises a base resin whose dielectric breakdown voltage exceeds that of polyphenylene sulfide and whose spiral flow length exceeds that of polybutyrene terphthalate. As the base resin has a high fluidity, there is only a limited risk that a defect such as a weld line is caused when molding a thin case. In addition, while the thickness of the case and the electrical insulation properties are in proportion to each other, the case comprising the base resin can ensure sufficient electrical insulation properties even if the case is formed thin.

摘要： In a vehicle alarm sound outputting device, in a filter coefficient generator, interpolation of filter coefficients is carried out in accordance with the relative position between a vehicle and an object by using head related transfer functions serving as base data in a filter coefficient interpolator. Particularly when the object moves, the relative position of the object is sequentially grasped while following the movement of the object, and the interpolation of the filter coefficients is carried out. In a filter coefficient synthesizer, the interpolated head related transfer functions and the cross-talk removing filter coefficients are combined with one another to generate virtual sound source filter coefficients. The virtual sound source filter coefficients generated in the filter coefficient generator are convoluted with the audio data of an alarm sound, and audio signals of the virtual sound source are generated in connection with the right and left speakers. Accordingly, a driver can hear an alarm sound from the position at which the object exists (in accordance with movement of the object).

摘要： In a vehicle alarm sound output device and a program, position data of an obstacle(s) and sound data of an alarm sound are output from an obstacle detector to DSP of a virtual sound source generator. Position data of a tire having air pressure abnormality and sound data of an alarm sound are output from an abnormality detector to DSP. Position data of a target object of a route guidance and sound data of a voice are output from a position detector to DSP. In DSP, an audio signal with which a virtual sound source can be implemented is created by using a detection signal/localization position converting table and head related transfer functions, and the audio signal thus created is output to a sound output unit. In the sound output unit, the signal corresponding to the audio signal is output to speakers so that a passenger(s) can hear an alarm sound such as a warning sound, a voice guidance or the like from the localization position of a virtual sound source.

摘要： An air bag system for a front-seat passenger, includes a main body portion of an emblem is brought into contact with a surface of an instrument panel at a reverse face thereof, a bolt provided on the reverse face of the main body portion to protrude therefrom passes through the instrument panel and a mounting portion of an air bag module and a nut screwed on and fastened to the bolt so that the air bag module is fixed to the instrument panel easily and rigidly without using heat clamping which is less stable in quality. There is no risk that surface sinks are generated in the surface of the instrument panel to thereby deteriorate the aesthetic appearance thereof, since there is no need to provide bosses on a reverse face of the instrument panel for heat clamping.
