Abstract: An electromagnetic rotating machine having drive windings and position control windings and components enabling operation generally in accordance with the following. 
     The controller 82 estimates displacement of the rotor 50 by computing from the currents 1u2, 1v2 and 1w2 of the position control windings C2, the primary current frequency command value 2ω, and the output current (or voltage) from the inverter 56. On the basis of the estimated rotor displacement, the modulator 84, two-phase/three-phase converter 86 and voltage control inverter 88 control the currents of the windings C2. This unbalances the magnetic field generated by the motor windings C4, so that radial magnetic force acts on the rotor 50 to control the rotor position.

Abstract: A process for producing a coated film continuously, comprises the steps of:
     running a substrate film; and   extruding a coating composition having a viscosity of 0.1 to 100cps at 20°C through a slit of a die onto a surface of the substrate film to produce a coating layer having a thickness of 0.1 to 20 µm over the substrate film.

Abstract: An electrode for connecting an external electric wire to a heated body heated to a high temperature. 
     The electrode of this invention comprises a high temperature side electrode made of a conductor connected to the heated body, and a low temperature side electrode connected at one of the ends thereof to the high temperature side electrode and at the other end thereof to the external electric wire. 
     The low temperature side electrode is formed by covering a conductor disposed at the center by a covering material through an insulating material, and the conductor of the low temperature side electrode is made of a material having a smaller conduction resistance than that of the conductor of the high temperature side electrode. 
     Because the conductor of the low temperature side electrode is made of the material having a smaller conduction resistance than that of the conductor of the high temperature side electrode, the increase of the resistance value can be restricted even when the conductor is extended so that the temperature of the connecting portion with the external electric wire becomes lower.

Abstract: A double forward DC-to-DC converter with soft-PWM switching
provides two voltage pulses to the output low-pass filter within
one switching cycle (hence, the name double forward). The double
forward DC to DC converter includes a transformer having a single
primary winding and a two secondary windings. A main switch,
under the control of a PWM control circuit, is connected is series
with the primary winding. An auxiliary switch is coupled across
with the main switch by way of a resonant capacitor. The resonant
capacitor and auxiliary switch are used to automatically reset the
transformer core while the main switch is on back to the voltage
source connected to the transformer primary. A diode and snubber
capacitor is connected across the drain-source terminals for both
the main and auxiliary switches for minimizing switching losses.
The current mirror used in prior art is abandoned in order to
avoid the locked-up mode of operation. 
     The secondary windings of the transformer are connected to a
pair of saturable reactors which, in turn, are connected to
rectifier diodes in order to eliminate the reverse recovery losses
of the rectifier diodes. A freewheeling diode is connected across
the secondary winding and cooperates with the saturable reactors
to maintain the load current to the secondary windings during the
transitions of the main and auxiliary switches.

Abstract: A developing unit for an electrophotographic processor is
described. The unit includes a frame in which the
following elements are supported. A developing roller
supplies toner to a photo-sensitive drum so as to develop
an electrostatic latent image formed on the surface of the
photosensitive drum. A supply roller supplies toner to the
developing roller. A conductive seal is attached to the
frame and prevents toner from escaping between the
developing roller and the frame. The seal is grounded or
has a reference voltage applied to it, so as substantially
to eliminate any electric charge of the toner remaining on
the surface of the developing roller after the
electrostatic latent image of the photosensitive drum has
been developed. Thus, the ghost phenomenon in which
characters or pictures of a previous rotation of the
developing roller dimly appear in the next image can be
prevented.

Abstract: The telecommunication system includes several exchanges coupled with each other, and at least one coupled control unit. A path allocation is performed in the exchanges using data stored in exchange tables, by forming a connection between the coupled exchanges which contain respectively individual Least-Cost-Routing data. At an incoming call the respective exchange recognizes only the beginning and the end of the path, so that the call is possibly permanently redirected between two exchanges because of a current overload or interruption of the path, whereby an endless loop emerges. The control unit forms at least one connecting tree, outgoing from one exchange to other exchanges of the telecommunication system which contains loop-free connections as branches. The connection tree is converted into an exchange tree through inquiry of pairs of exchanges in the branches and through elimination of branches containing the respective pair in reverse order, whereby loop-free exchange trees are formed.
