The transducer comprises an armature and a core. Both pieces are E-shaped, and their geometrical dimensions are chosen so that when their central legs come into mutual contact, air gaps still exist between both pairs of outer legs where these face each other. A coil bobbin is fixed to the core and forms a straight guide for the central leg of the armature. The frontal surfaces of the outer legs are chamfered so that the limiting surfaces of the air gaps are inclined with respect to the travel di...

An alternating current generator for a car comprises the first centrifugal fan which is fixed to one end of the rotor and has a diameter smaller than that of the rotor, the first ventilating hole for feeding a coolant air which is formed in the end portion in the axial direction of the bracket in the side of the centrifugal fan, the second ventilating hole for discharging the coolant air which is formed in the cylindrical portion of the bracket in which the first ventilating hole is formed, the ...

A method is provided for gelling a dielectric in an alternating current capacitor of the type having a housing enclosing a pair of convolutely wound electrodes and dielectric spacers interleaved therebetween for separating the electrode with at least one of the electrodes being formed by a metallized film and using a dielectric of soybean oil, the method comprising adding an alkylhydroxyphenlalkanolyhydrazine compound to the soybean oil to gel the same within the housing so as to reduce its mobi...

Voltage booster converter comprising a pair of input terminals A and B for connecting a DC input voltage Vin between these two terminals; a pair P.sub.0 of switches SB, SH in series connected by the switch SB to the input terminal B, the input terminal A being connected across an input inductor Lin to the connection point between the two switches SB and SH in series, each switch SB, SH comprising a control input so as to be placed simultaneously, one in an on state the other in an isolated state...

An alternating current electric machine, namely, a small-power asynchronous otor, has two pairs of electric poles which can be supplied with either three-phase or single-phase alternating current. The machine is considerably simpler than classic motors, being provided with a stator having single cylinder poles and four or six coils. The stator is made from grain-oriented steel sheet.

A heavy particle linear accelerator employing rf fields for transverse and ongitudinal focusing as well as acceleration. Drift tube length and gap positions in a standing wave drift tube loaded structure are arranged so that particles are subject to acceleration and succession of focusing and defocusing forces which contain the beam without additional magnetic or electric focusing fields.

A cabin pressure control system has two independent controllers, one of which is used as primary controller while the other serves as standby. On alternate flights the identity of primary and standby controller are switched so that both controllers will be regularly utilized.

An alternating phase shift mask. The alternating phase shift mask includes a transparent substrate, a light-shielding layer disposed on the transparent substrate to define a transparent array consisting of a plurality of first phase rows and a plurality of second phase rows alternately interposed between the first phase rows. The alternating phase shift mask further comprises a phase interference enhancement feature disposed a predetermined distance from the outermost row of the transparent arra...

An alternating current generator of the invention has three armature windings, which are wound from a winding start end connected to a neutral point to winding finish ends, and a stator that is connected to the neutral point in Y-connection at a phase difference of 120 degrees, respectively, and configures a three-phase power source, wherein the generator comprises two taps provided at predetermined positions from the winding start end to the winding finish ends of two armature windings out of t...

An alternating current electrical generator creates three different and distinct magnetic fields between would coil elements and rotating magnets, two fields of which are induced fields caused by magnet rotation. A plurality of magnets are positioned such that they extend outwardly from a rotating shaft. The magnets are circumferentially spaced around the shaft such that the north polar end of one magnet follows the south polar end of the next magnet or such that the polar end of one magnet foll...
