Abstract: ELECTROMECHANICAL TRANSLATION APPARATUS          Abstract An electromechanical translator apparatus (24) which is especially suitable for use as the coarse positioner in a scanning tunneling microscope (10) (STM) which enables a specimen to be positioned with a resolution in the order of atomic distances (in the nanometer range) has a housing (26) containing a piezeoelectric driver in the form of a sleeve  (32) surrounding a shaft (21) on one end of which the specimen (18) may be mounted.  The driver sleeve (32) has an extension element (2) with clamping elements (1,3) on opposite ends thereof and is connected and referenced to the housing at a region (4) thereon spaced from the extension element  and preferably between the extension element (2) and the one of the clamping elements (1) closest to the end of the shaft (22) on which the specimen (18) is mounted (in the direction of controlled movement toward the scanning tip (36) of the STM).  Because of the position of the connection(36) and referencing of the housing (26), undesired movement of the shaft such as upon engagement and releasing of the clamping elements (glitch movement) or due to piezoelectric material creep effects or spurious movement of the shaft (21) due to power supply noise, which changes the voltage applied to the extension element, is avoided thereby enabling controlled motion with resolution in the range required for STM applications and other applications which require high resolution controlled motion.

The basic metal carboxylate has the formula:              R'-CO2M'(OH)n? zHm X where (i)  R' is an organic radical; (ii)  M' is any metal that has a valence of 3 or 4; (iii)  x is BO3-, SO4=, Cl-, NO3-, R"CO2-, where R" is an organic radical; (iv)  n and m correspond to the valence of (M'-1) and x respectively; and (v)  Z has a value sufficient so that said R'-CO2M'(OH)n is substantially water soluble. A layer of the solution is applied to the fiber and the fiber is exposed to a temperature sufficient to form an oxide surface.  The fibers can be used to make polymeric composites.  Fibers having the above-described coating are impregnated with a resin, stacked in layers and exposed to pressure and optional heat.

Abstract: The invention concerns a frequency modulation broadcasting transmitter in which the output oscillator at the transmission frequency is modulated not directly by the audiofrequency signal but through the intermediary of a phase locking loop comprising a phase comparator supplied, on the one hand, by the output signal filtered from a picture or image frequency rejection mixer. This mixer receives, on the one hand, a modulated intermediary frequency signal from a modulator and, on the other hand, the output signal of the oscillator at the transmitting frequency FS, the reference frequency Fo1 being determined as a function of the central transmitting frequency and of the intermediary frequency Fo1=FS-F1.
