    Abstract: A laminar longitudinal-effect type piezoelectric or electrostrictive driver which is displaced upon application of an electric field thereto. The driver includes laminar electro-mechanical converting elements each undergoes a displacement in a direction of the electric field due to the longitudinal mode of the reverse piezoelectric effect or the electrostrictive effect, and the temperature compensating elements each of which is interposed between the appropriate adjacent two laminar electro-mechanical converting elements. The temperature compensating elements have a higher coefficient of linear thermal expansion in the direction of the electric field or direction of displacement of the driver. The driver is suitably usable for an actuator for operating a print element of a printer, for example.

    Abstract: A laminate piezoelectric actuator element comprising plural laminated piezoelectric subunits each of which comprises piezoelectric ceramic layers for generating longitudinal electrostrictive strain with a voltage, internal electrodes for applying the voltage to said piezoelectric ceramic layers, and piezoelectrically-inactive portions which correspond to parts of the piezoelectric ceramic layers having no internal electrodes laminated thereon. The piezoelectric ceramic layers and the internal electrodes are alternatively laminated on each other to form a piezoelectric subunit. An adhesive member having an attaching area equal to or smaller than an area of each internal electrode is provided between the neighboring piezoelectric subunits to thereby attach and assemble the plural piezoelectric subunits to form the piezoelectric actuator element and form slit portions between the laminated piezoelectric subunits in such a manner as to surround the adhesive member. The piezoelectric actuator element further includes external electrodes provided at both sides thereof in such a manner as to be connected to the internal electrodes to apply the voltage to the internal electrodes.

    Abstract: A nuclear magnetic resonance apparatus incorporating a first trans-receiver coil, an internal lock coil, a decoupling coil, means for tuning said coils to desired frequencies, a first trans-receiving system for supplying the first trans-receiver coil with a first nuclear (such as .sup.1 H) resonance RF wave and detecting the first nuclear resonance F.I.D. signal, a second trans-receiving system for supplying the first trans-receiving coil with a second nuclear (such as .sup.13 C) resonance RF wave and detecting the second nuclear resonance F.I.D. (Free Inductance Decay) signal, a third trans-receiving system for supplying the internal lock coil with a third nuclear (such as .sup.2 D) resonance RF wave and detecting the third nuclear resonance signal, and a transmission system for supplying the first nuclear resonance RF wave to the decoupling coil, it being possible in said apparatus to observe different types of nucleus, viz; .sup.1 H and .sup.13 C without removing the internal lock by employing a third nucleus such as .sup.2 D so that the first and second nuclear spectrum can be observed at high resolution by first nuclear decoupling.
