Title: Thin structures having a piezoelectric effect devices equipped with such structures and in their methods of manufacture
IPC: H01L41/45
Filed: 1973-09-07
Abstract: 1448013 Piezoelectric transducers AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE 7 Sept 1973 [8 Sept 1972] 42229/73 Heading H4S [Also in Division H1] Thin dielectric elements are conditioned to carry on one or on both surfaces electrostatic charges of opposite signs in such amounts that the field in the neighbourhood of the surface or surfaces is substantially nil. It is stated that, when supplied with electrodes, the elements exhibit piezoelectric and pyroelectric effects and they may be used, e.g. in ultrasonic transducers, pressure sensors and heat-radiation sensors. The elements may have a thickness between 3 and 500 Á, preferably 10 to 30 Á and may be made, e.g. of polypropylene, polystyrene, a polycarbonate, a polyamide or of mica. The element is initially enclosed between electrodes with a slight gaseous spacing (e.g. 2-3 Á) created, e.g. by surface irregularities or by perforated separating shims, the spacing and the gaseous pressure being adjusted to provide a convenient value of ionization voltage. The distance between the element and the electrodes may also be determined by the interposition of a solid sheet, e.g. of glass. A voltage V lying between the ionization voltage V 1  of the gas and the breakdown voltage of the element V 2  (V 2 >V 1 ) is applied for a time sufficient to establish opposite charges on the surfaces of element giving rise to a polarization voltage V 0 . The applied voltage is removed and an opposite voltage V<SP>1</SP> applied to the electrodes. The voltage V<SP>1</SP> has an absolute value less than V 2  + V 0  and greater than V 1  - V 0  if this amount is positive (if V 1 -V 0 <O, this difference will tend to zero when V is removed, in which case V<SP>1</SP> is initially zero and is increased to V 1 ). The voltage V<SP>1</SP> is applied until V 0  becomes zero. Typical voltage values are, V 1 =900 v., V 2 = 4000 v., V=2500 v. The charges which accumulate on the surfaces are of the order of 3À10<SP>-3</SP> coulomb/cm.<SP>2</SP> both positive and negative. In an alternative method, the charges are injected by an electron gun and a positive ion gun.

Filed: 1971-09-14
Abstract: 1346797 Photographic shutters HATTORI TOKEITEN KK 14 Sept 1971 [25 Sept 1970] 42788/71 Heading G2A An electric shutter operating mechanism includes a first driving member 15 adapted to cause opening and closing of the shutter by movement in one direction, a second driving member 21 coupled by a first spring 22 to the first member and meshing with a third driving member 26 carrying an armature 31 of an electromagnet 34, there being a second spring 30 biasing the third driving member in a shutter closing direction. The electromagnet is included in a time delay electric control circuit, e.g. a Schmitt trigger circuit whereby when energized the electromagnet retains the armature but on release, after a timed delay, the third driving member rotates to cause the second and first members to close the shutter. In operation Fig.1 (not shown) with the shutter blades 2 closed, a spring biased lever 7 is released and member 15 rotates so that arm 13 actuates lever 11 to move shutter ring 1 via pin 4; simultaneously, rotation of projection 3 allows switch contacts 36 to spring back to 38 so allowing a condenser (42) Fig.4 (not shown), in the control circuit, to charge up through a photo-cell controlled resistor (41) and armature 31 to be retained on 34 by current flow through transistor 44. Rotation of member 15 causes abutment of turn-ups 18, 23, their impact being reduced by counter rotation of 21 on spring 22. A residual clockwise motion allowing teeth 25, 32 to mesh. When condenser (42) is saturated, electromagnet (34) is de-energized through transistors (43, 44) so allowing third member 26 to rotate anti-clockwise on the spring 30 and rotation of members 21 and 15 to close the shutter by impact of arm 20 on pin 5 of the ring. The ring movement also shorting the circuit by closing contacts 36, 37.

Title: Improvements in or relating to demodulators for frequency modulated waves
Inventor: BATTAIL GERARD PIERRE ADOLPHE
IPC: H03D3/02
Filed: 1967-09-20
Abstract: 1,154,438. Frequency demodulators. G. P. A. BATTAILand P. C. BROSSARD. 20 Sept., 1967 [10 Oct., 1966], No. 42822/67. Addition to 960,807. Heading H3A. A spectrum analyser for use in the demodulating system described in Specification 960,807 comprises a local oscillator 310 the output of which is mixed with the input signal on line 31 to provide the input to the analysing system, the output of which controls the frequency of the local oscillator. In Fig. 2, the output of mixer 300 is fed to three resonant circuits 301- 303 of successively higher resonant frequencies, the outputs of which are phase-corrected in units 3001 and 3003 and compared in subtraction units 331 and 332. If the frequency is too low, the output of circuit 301 will exceed that of the reference circuit 302 and the synchronous detector 3301 will produce a postive output which is detected by a sign detector 341; this produces a pulse which is fed to the input 3601 of a reversible counter feeding a decoder 370 which provides the output voltage on line 36 and a control voltage for restoring the frequency of oscillator 310. Similarly if the frequency is too high a pulse is fed to the other input 3602 of the reversible counter. The sign detectors 341 and 342 re-set themselves through delay units 351 and 352 which allow time for the correction of the local oscillator frequency so that the same error does not cause a succession of pulses to be fed to the counter. Since noise may cause incorrect operation of the system so far described, the outputs of the two outer resonant circuits 301 and 303 are oppositely phase shifted by about 63 degrees in units 3004 and 3005 and compared by means of subtraction units 333 and 334 and synchronous detectors 3303 and 3304, the outputs of which are inverted and fed to AND gates 361 and 362. Thus pulses are fed to the counter only when the output from an end resonant circuit (301 or 303) exceeds that from the centre circuit (302) and that from the other end circuit. In a simpler circuit, Fig. 4 (not shown), the outputs of two resonant circuits are compared by means of a subtraction unit (3310) and a synchronous detector (3311) the output of which controls the local oscillator frequency. In this case the output is not quantized, and the local oscillator 310 may provide the final output instead of filtering the output on line 36 and using the filtered output to frequency modulate a further oscillator (35, Fig. 1, not shown).
