Patent EP-0748039-A2 (EP)
Inventor: KYODO YASUMASA
IPC: H02P6/16
Filed: 1996-06-07
Abstract: The present invention provides a rotation position detecting circuit for a sensor-less motor, and a motor device, which do not use a back electro-motive voltage. A motor (1) is rotated and driven by adding a sensor signal having a high frequency to a sine wave drive signal and a cosine wave drive signal through adders (5S) and (5C), respectively. A sensor signal is extracted and demodulated from a signal flowing in the motor (1) by a band pass filter (9), and this is defined as a rotation position detection signal. In the sensor signal from the band pass filter (9), its current value is changed corresponding to a change of an impedance resulting from a rotation of a magnet of the motor. It is possible to detect the rotation position of a rotor magnet, by detecting the change of the current value.

Abstract: A process for forming a dual-damascene interconnect employs a spun-on organic layer above an interlayer dielectric having a set of apertures for vias that forms tapered regions about the apertures without penetrating the apertures. The slope of the tapered regions is transferred during the etching process to form self-aligned tapered vias. A silicon substrate (10) over which an oxide or other insulating layer (110) is first formed. A layer first level of metal interconnect (120) and a layer of SiO 2  (130) are formed insequent onto the structure, then an aperture (140) extending down to and stopping on metal interconnect layer is formed. Now an anti-reflective coating (ARC) layer (135) is put down and spun onto the structure. Unexpectedly, the surface tension of the ARC layer prevents the ARC material from getting into the aperture but forms a tapered rim at its edge (as illustrated). After baking the ARC layer, a layer of resist (150) is deposited, exposed, and developed to form a novel aperture (142). An non-isotropic etch using CF 4 /O 2  chemistry as the etching gas is performed, then both the resist and ARC layer are stripped. The result is an aperture having a tapered bottom selection which, when filled with metal (147/147) and polished to become level with the top of SiO 2  layer produces the chemical Damascene interconnect.

Abstract: Upshifting is performed in a short time without
giving rise to shocks. For that purpose, at the time of
upshifting, a hydraulic pressure (QUPOFF) of a hydraulic
engaging element on disengaging side is controlled such
that the input and output speed ratio ("Gratio") of a
transmission is decreased to, and held at, a predetermined
slipping region (YG(N)S) that is lower than an engaging
region (YG(N)L) - YG(N)H) to be set based on a gear ratio
which is established by the engagement of the hydraulic
engaging element on the disengaging side. The hydraulic
pressure (QUPON) of a hydraulic engaging element on
engaging side is gradually increased. When "Gratio" once
falls below YG(N)L and then increases up again to YGCONOK,
QUPOFF is lowered to a predetermined low pressure
(QUPOFFB) at a lapse of a predetermined time (YTMUP8).
Once "Gratio" > YGCONOK, QUPON is increased to a
predetermined high pressure QUPONB at a lapse of a second
predetermined time YTMUP3. YTMUP8 is set so as to become
shorter with an increase in a vehicle speed, and YTMUP3 is
set so as to become longer with an increase in the vehicle
speed.

Abstract: Process steps to provide communication
between a web browser capable of initiating
execution of a platform-independent segment of
executable code and a peripheral having an HTTP
server and an SNMP agent. A first packet is
transferred to the HTTP server, and, in response, a
file is transmitted to the web browser. The file
contains a reference to a platform-independent
segment of executable code. Upon processing the
file, this code segment is requested from the HTTP
server. After the web browser receives the
executable code from the HTTP server, execution of
the code segment is initiated in order to create an
SNMP client. Execution of the code segment also
causes a packet to be sent from the SNMP client to
the SNMP agent in the peripheral. In response to
this packet, information concerning the peripheral
is transferred from the SNMP agent to the SNMP
client.

Abstract: Microchips are provided, which control both the rate and time of release of multiple chemical substances and which allow for the release of a wide variety of molecules in either a continuous or pulsatile manner. In all of the preferred embodiments, a material that is impermeable to the drugs or other molecules to be delivered and the surrounding fluids is used as the substrate. Reservoirs are etched into the substrate using either chemical (wet) etching or ion beam (dry) etching techniques well-known in the field of microfabrication. Hundreds to thousands of reservoirs can be fabricated on a single microchip using these techniques. A release system, which includes the molecules to be delivered, is inserted into the reservoirs by injection, inkjet printing or spin coating methods. Exemplary release systems include polymers and polymeric matrices, non-polymeric matrices, and other excipients or diluents. The physical properties of the release system control the rate of release of the molecules. The reservoirs can contain multiple drugs or other molecules in variable dosages. The filled reservoirs can be capped with materials that either degrade, dissolve, or allow the molecules to diffuse passively out of the reservoir over time or materials that, upon application of an electric potential, oxidize to form soluble compounds or ions that dissolve into the surrounding fluids. Release from an active device can be controlled by a preprogrammed microprocessor, remote control, or by biosensors.

Title: Procede et appareil pour la fabrication d'electrodes negatives et positives autodopantes destinees a des photopiles au silicium et a d'autres dispositifs
Inventor: MEIER DANIEL L
IPC: H01L31/068
Filed: 1998-05-05
Abstract: Selon l'invention, une électrode autodopante au silicium est formée en premier lieu d'un métal (composant principal) qui forme un eutectique avec le silicium. Un dopant du type p, destiné à une électrode positive, et un dopant du type n (destiné à une électrode négative), est allié au composant principal. L'alliage constitué du composant principal et du dopant est appliqué sur un substrat de silicium. Le substrat et l'alliage qui y est appliqué sont ensuite chauffés à une température supérieure à la température eutectique de l'ensemble composant principal-silicium, de sorte que le composant principal se liquéfie plus qu'une proportion eutectique du substrat de silicium. La température est ensuite abaissée dans le sens de la température eutectique pour permettre au silicium fondu de se reformer par épitaxie de la phase liquide et ce faisant, d'incorporer des atomes de dopant dans son réseau redéveloppé. Lorsque la température est tombée en dessous de la température eutectique de l'ensemble composant principal-silicium, le silicium, qui ne s'est pas encore reformé en réseau, constitue un alliage en phase solide avec le composant principal et le dopant non utilisé restant. Cet alliage formé par le composant principal, le silicium et le dopant inutilisé constitue le matériau de contact final. Selon une variante, une électrode autodopante peut être formée à partir d'un métal non allié appliqué sur un substrat de silicium. Le métal et le substrat sont chauffés à une température supérieure à la température eutectique de l'ensemble métal-silicium, dans un gaz ambiant, dans lequel une source d'atomes de dopant vaporisés a été introduite. Les atomes de dopant se trouvant dans le gaz ambiant sont absorbés par le mélange métal-silicium en fusion dans une bien plus grande mesure qu'ils ne le sont par les surfaces du substrat de silicium solide. La température est ensuite ramenée à une valeur inférieure à celle de la température eutectique de l'ensemble métal-silicium. Pendant cette réduction de température, la couche de silicium redeveloppée dopée et le matériau de contact final formé par l'alliage métal-silicium sont créés selon le procédé décrit ci-dessus.
