Abstract: A semiconductor device of the quantum interference type has channel means (4,6;55) for passing carriers from a source region (31;36;52) to a drain region (33;56) of the device, at least part of the said channel means (4,6;55) comprising two conductive paths extending in parallel between the source and drain regions (31;36;52/32;56), and field control means (35;59) arranged for subjecting the said conductive paths to a selectively variable electric or magnetic field so as to control the passage of carriers through the said channel means (4,6;55). The device is provided with carrier-energy filtering means (40;53) arranged for restricting the energy levels, of carriers entering the said channel means (4,6;55), to a predetermined narrow band of energy levels. In this way quantum interference in the device can be improved as compared with a known semiconductor device of the quantum interference type.

Abstract: Sont décrits des systèmes de test d'animaux transgéniques non humains visant à détecter des mutagènes et des carcinogènes. On utilise des techniques recombinantes à base d'ADN afin de créer des gènes de test uniques, ainsi que des signaux de régulation afin de détecter des fréquences augmentées de mutations produites par des mutagènes et des cancers induits par des carcinogènes. On introduit les gènes de test dans la lignée germinale d'animaux transgéniques non humains, afin de produire un panel unique de bioanalyses visant à la détection de mutagènes et de carcinogènes. Les gènes de test de l'invention peuvent coder n'importe lequel parmi plusieurs gènes différents, dont l'expression pourrait être détectée chez un animal transgénique. Toutefois, le gène de test est mis au point de sorte que l'expression du produit du gène de test est soit empêchée soit inhibée, à moins que le gène ne soit activé par un mutagène ou un carcinogène.

Abstract: A recording/reproducing apparatus using a tape medium comprising two reels (1a), (1b) for winding and sending the tape, drive means (2a) and (2b) for driving the reels (1a) and (1 b), tape speed detect :means(3) that produces speed data on the tape, a periodical desired value circuit (41) for producing a desired speed value of the tape, a tape speed error detecting means (5) for producing an error quantity between the output of the tape speed detector means (3) and the output of the periodic desired ;value circuit (41), and a drive side determining means (6) which sends a drive instruction to the reel lof the winding side at the time of acceleration and which, at the time of deceleration, sends a drive instruction corresponding to the output of the tape speed error detecting means (5) to the reel of the sending side, in order to control the tape speed by driving the reels. The deceleration torque is now applied to the reel of the sending side that could not be applied to the reel of the winding side since the tape slackens. Therefore, the tape speed can now be decelerated within short periods of time, and the tape transport enables the speed of the tape to be accelerated or decelerated stably at all times through the same processing.

Abstract: A set of elements for the construction of a self-supporting or free-standing noise barrier which can be planted with vegetation has a number of troughs (1) which are to be arranged above one another and can be planted with vegetation and the bottoms (6) of which have penetration openings for water, it being possible for the side walls of the troughs (1) to stand vertically or at an angle. On their end sides, the troughs (1) have bearing surfaces or guides (2), with which they fit between posts or columns (3) which can be anchored in the ground. In the bottom (6) of the troughs (1), there are anchored, as penetration openings, pipe pieces (7) which have a continuous opening directed into the next lower trough (1) and project upwards to part of the trough height as an overflow to form a catchment space, to be filled with water, for the trough and the vegetation therein. Therefore, before water can run out of such a trough (1) through the opening situated in the bottom (6) into the next lower trough, said trough is filled with reserve water to the height of the inlet opening in the pipe pieces (7). Furthermore, a collecting tray (9) for rain with at least one drain (11) in its bottom (10) can form an endpiece which can be positioned on the top trough, it being possible however for this collecting tray (9) itself also to be a trough (1). <IMAGE>

Abstract: The rotation speed of two-phase induction motors is controlled by means of simultaneously changing the frequency, in the same sense, of the amplitude-limited supply currents in the stator windings, with a constant phase shift of  pi /2. As a result of the amplitude limiting, periodically frequency-dependent drive and braking states are generated in the rotor of the induction motor which allow the rotation speed to be influenced quickly. Used for actuating drives and constant speed drives, especially for small motors with disc or bell rotors. <IMAGE>

Abstract: A vacuum cleaner (10) is disclosed having an on-board electrostatic filtration device (20) for removing ultra fine particles from the suction air stream which is discharged into the vacuum cleaner's dirt collection receptacle. The electrostatic filtration device (20) includes a finely woven conductive mesh made from two electrically insulated sets of conductive filaments (22,24) between which a low voltage electrical potential difference is applied. The polarity of the electrical potential difference is periodically reversed at low frequency to assist in maintaining filtering effectiveness notwithstanding the accumulation on the mesh of significant amounts of retained particulate matter. High permitivity material (64) is incorporated between filaments (22,24) to enhance electric fields in the mesh created by the electrical potential difference.
