Abstract: A safety and regulation valve unit for a gas installation,
particularly a heating installation, comprises a duct (2)
through which the fuel can flow between an inlet (4) and
at least one outlet (6,8). On-off fuel-valve means (10)
are interposed in the duct (2) between the inlet (4) and
the at least one outlet (6,8), and there is a movable
device (18) for controlling the valve means as well as
actuator means acting on the movable device in order to
move it towards a first operative position in which it
cooperates with the on-off valve means (10) in order to
put the inlet (4) into communication with the outlet (6,
8). The actuator means comprise a reversible motor (20)
with a rotor (22) connected to a male-and-female screw
(24a,26) coupling acting on the movable device (18) to
translate it towards the first operative position and to
control the on-off valve means (10).

Abstract: For use with a power factor correction circuit (120), a current mode
controller (140), to achieve power factor correction thereof. In one embodiment, the
controller (140) includes: (1) a modulator (143 to 150, 155), coupled to a switch in the
power factor correction circuit (120), that senses an electrical characteristic and a
current passing through the power factor correction circuit and provides, in response

to an input of the power factor correction circuit (120), that provides a compensation
signal to the modulator that is a function of a rectified line voltage provided to the input
of the power factor correction circuit. The compensation signal causes the modulator to
modify the control signal to reduce a total harmonic distortion (THD) of the power
factor correction circuit.

Abstract: The present invention relates to an apparatus for
reading from and/or writing to optical recording media
having a scanner (1) for scanning the recording medium,
a coarse drive (5) for moving the scanner (1) relative
to the recording medium and a measuring device for
determining the travel of the scanner (1). 
     The object of the present invention is to propose an
apparatus of this type in which it is possible to
determine the position of the scanner as exactly as
possible, the intention being for this to be ensured
even in the event of a high movement speed or
acceleration. 
     This is achieved according to the invention by virtue
of the fact that the measuring device has an optical
interference generating means (17) and an optical
interference detection means (21). 
     The invention is particularly advantageous for
apparatuses which require rapid access to extremely
diverse locations on the recording medium, as is the
case with apparatuses appertaining to optical data
storage, for example CD-ROM or DVD-ROM apparatuses.

Abstract: A step-motor-driving device includes (a) a step-motor having driving-windings
in plurality of phases, (b) an exciter for supplying power to excite
driving-windings, (c) a position detector for detecting a position of a mover of
the motor and outputs a position-detecting-signal, and (d) an excitation-timing-controller

and outputs an exciting signal to the exciter responsive to an
input of one of the driving-instruction-signal and the position-detecting-signal.
The excitation-timing-controller outputs the exciting signal responding an
input of the driving-instruction-signal when an excitation-switch of the
driving-winding responsive to the driving-instruction-signal directs torque in
a direction effective for the motor to rotate in a desirable direction, and the
controller outputs the exciting signal responding an input of the position-detecting-signal
when the excitation-switch of the driving-winding responsive
to the driving-instruction-signal directs torque in an unfavorable direction for
the motor to rotate in the desirable direction. This structure allows the step-motor-driving
device to be free from jumping "out of sync".

Abstract: Methods of making a full-color organic light-emitting display are
disclosed. The methods include ink-jet printing of fluorescent dopants selected to
produce red, green, or blue light emission from designated subpixels of the
display. The dopants are printed sequentially from ink-jet printing compositions
which permit printing of dopant layers over a light-emitting layer containing a
host material selected to provide host light emission in a blue spectral region. The
dopants are diffused from the dopant layer into the light-emitting layer by
exposing the light-emitting layer and the dopant layers to vapor of a fluid or fluid
mixture. When an ink-jet printing composition is formulated with a printing fluid
having fluid vapors which promote dopant diffusion, the steps of ink-jet printing
and diffusing of dopants can be combined to form a selectively doped light-emitting
layer.

Abstract: The invention provides a software instrumentation tool operative to control the
execution of a target program, and to execute user-specified instrumentation actions upon
occurrence of corresponding user-specified events during target program execution.
Advantageously, the instrumentation tool permits the instrumentation actions to be
implemented without modification of the target program code, and can be used to provide
any desired type of instrumentation on any target program. In an illustrative embodiment,
the instrumentation tool includes a frontend portion which provides a creation graphical
user interface (GUI) to the tool, and a backend portion which controls execution of the
target program and executes the user-specified actions. The frontend portion also
includes, for a given target program, a created GUI which is created by a user for
providing selected instrumentation functions for the given target program. The frontend
and backend portions of the instrumentation tool may each be running on a different
machine, or both may run on the same machine. The invention may be used in a wide
variety of applications, including application program modification and management, fault
tolerance, real-time collaboration, process monitoring, software rejuvenation and graphical
interface generation.

Abstract: An engine mount for a vehicle has a first rigid fixture (12) for
attachment to the engine and a second rigid fixture (13) for
attachment to the chassis or body, an armature (14) attached to
the second rigid fixture (13), and a resilient rubber support
(10) between the first fixture (12) and the armature (14) for
flexing in response to engine vibrations. The rubber support
(10) defines a working chamber (22) containing hydraulic fluid
which is in communication with a compensation chamber (37) via
a helical conduit (38), so that engine vibrations are at least
partially damped by oscillation of fluid in the conduit (38)
between the two chambers (22,37). Two apertured grills (24,52)
define a valve chamber (51) in which a flexible disc valve (46)
is oscillatable. The lower grill (52) is rotatable by means of
a control rod extending externally of the engine mount. It
carries inclined ramps (72) cooperating with similar ramps on a
lower plate (55) so that rotation of the lower grill (52) alters
the free play of the disc valve (46). In this way, therefore,
the flap valve (46) can be controllably rendered operative over
a wide range of vibration amplitudes so as (for example) to
reduce the dynamic stiffness of the engine mount during engine
idling. Other means of adjusting the operation of the flap
valve are described.

Abstract: In the method for managing the use of temporary
mobile identifiers (TIDs), the mobile and the network
each store a list of TIDs for the mobile. Newly
determined TIDs are added to the respective TID list
such that the TIDs are stored in chronological order. To
determine a new TID, the network sends a first challenge
to the mobile and the mobile sends a second challenge to
the network as part of a TID update protocol. The
network and the mobile then determine the new TID based
on the first and second challenges. As communication
between the mobile and the network continues, the
respective TID lists are updated. Namely, when either
the network or the mobile confirms a TID, the TIDs older
than the confirmed TID are deleted from the TID list. In
communicating with one another, the mobile will use the
oldest TID on its TID list, while the network will use
the newest TID on its TID list.
