Filed: 2005-12-30
Abstract: A method for forming a micro contact hole of a semiconductor device is provided to obtain a relatively small size from the micro contact hole compared to that of a critical pattern of KrF and ArF exposure equipment by securing a stable process margin using an additional SAFIER(Shrink Assist Film for Enhanced Resolution) process on a photoresist pattern. A first photoresist pattern is formed on a semiconductor substrate(100). A second photoresist pattern is formed by performing an SAFIER process on the resultant structure. A crosslinkable organic material is coated along an upper surface of the resultant structure. A first bake process is performed thereon. A predetermined composition containing cross linkage inducing material is formed on the entire surface of the resultant structure. A second bake process is performed thereon. A third photoresist pattern(145) is formed on the resultant structure by removing the predetermined composition.

Title: Microfabricated double-throw relay with multimorph actuator and electrostatic latch mechanism
Inventor: HYMAN DANIEL J
IPC: H01H59/00
Filed: 2002-08-08
Abstract: This invention is a new type of relay that incorporates the functional combination of multimorph actuator elements with electrostatic state holding mechanisms in the development of a micromachined switching device. This combination of elements provides the benefits of high-force multimorph actuators with those of zero-power electrostatic capacitive latching in microfabricated relays with high reliability and low power consumption. The operation of the relay invention allows for several stable states for the device: a passive state using no power, an active state driving the multimorph actuator with some power, and a latched state electrostatically holding the switch rate requiring essentially no power. Multimorph actuators covered by this invention include piezoelectric, thermal, and buckling multimorph actuation mechanisms. These devices use one or more sets of actuator armatures in cantilever or fixed-beam configurations, and use one or more sets of electrostatic latch electrodes for state holding.

Title: Method for enabling multicast services and user equipment battery savings
Inventor: GOLDBERG STEVEN JEFFREY
IPC: H04B7/26
Filed: 2003-09-25
Abstract: A system and method for providing multicast services to wireless transmit/receive units (WTRUs) enhances battery life and provides for more efficient use of the radio resources. Each service, or a target group for a service,is assigned an identifier. The identifier is associated with a pointer to the transmission of data. Each WTRU searches for the identifier in order to know when the data will be transmitted. The WTRUs may receive the pointer from a number of different paging windows. The transmission of the data occurs after the last pointer is transmitted in order to guarantee that all the target WTRUs receive a pointer to the data prior to the transmission of the data.

Title: Viterbi bit detection method and device
Inventor: COENE WILLEM M J M
IPC: G11B20/22
Filed: 2003-08-13
Abstract: The present invention relates to a Viterbi bit detection method for detecting the bit values of bits of a channel data stream stored on a record carrier along an N-dimensional channel tube, N being at least two, of at least two bit rows one- dimensionally evolving along a first direction and being aligned with each other along at least a second of N-1 other directions, said first direction together with said N-1 other directions constituting an N- dimensional lattice of bit positions, comprising application of a row- based one-dimensional Viterbi bit detection method independent for each of the bit rows of said channel tube. To achieve a reliable bit detection a number of independent one-dimensional row-based Viterbi bit detectors, also known as sequence detectors, is used, one for each bit row in the channel tube : the interference between successive neighbouring bit rows is taken into account via the computation of the branch metrics (for the considered bit row), in which local bit decisions on the primary neighbouring bits in the neighbouring rows are used.

The electronic circuit (10) is further configured for performing one or more security-related operations or algorithms (14) in response to the internally confined device-specific security data. In this way, secure implementation and utilization device-specific security data for security purposes can be effectively accomplished. The security is uncompromised since the stored secret (C) is never available outside the electronic circuit, and the device-specific security data is internally confined within the circuit during usage or operation of the device.

Patent KR-20050085078-A (KR)
Inventor: HOSOKAWA TETSUO
IPC: G11B7/26
Filed: 2003-05-23
Abstract: A recording medium (11) comprising a medium body (12) for retaining data. On the surface of the medium body (12), a first print layer (15) having a first thickness and a second print layer (16) having a second thickness larger than the first thickness extend. A print protection layer (18) covering the first and second print layers (15, 16) is formed on the medium body (12). The print protection layer (18) has an inclined surface (19) inclined to the surface of the medium body (12). When a relative moving speed of X [m/s] is set between a recording track on the medium body (12) and a head, an inclination angle smaller then 0.49e-0.20Xis set between the inclined surface (19) and the medium body (12). An inclination angle set as such permits the head to smoothly slide on the surface of the print protection layer (18) and prevents the collision of the head against the print protection layer (18), thus ensuring a good relative displacement with respect to the head.

Title: Method and system for multimedia messaging service
Inventor: SHAO XIAOLING
IPC: H04L29/06
Filed: 2003-12-17
Abstract: The invention allows a portion of a multimedia message, usually the beginning part of the message to be delivered to and stored on a mobile terminal beforehand. When a user wants to view the message, the portion of the message stored locally will be played back immediately, while at the same time a user agent residing in the mobile terminal will contact a media server for the remaining contents using the streaming technology. This would give the user an impression that the whole message is stored locally since there is nearly no noticeable delay in the playback, thus providing a much better user experience. The partial contents downloaded can be a portion of the whole multimedia message, or an unrelated rich-media message provided by a third party as an advertisement. In this way, the usage of the local storage space on the mobile terminal will be much more efficient.

Filed: 2003-08-25
Abstract: A controller for controlling a power converter comprises a voltage vector control unit (11) for determining voltage vectors outputted from the power converter within one control cycle of PWM control and the times during which the voltage vectors are outputted according to voltage command variables Vu, Vv, Vw sent to the power converter, a voltage vector adjusting unit (12) for adjusting the output times of the voltage vectors received from the voltage vector control unit (11), and firing pulse generating unit (13) for generating signals for turning on/off semiconductor switching elements constituting the power converter according to the output times of the voltage vectors adjusted by the voltage vector adjusting means. The voltage vector adjusting unit (12) adjusts the zero voltage vector output time so as to ensure that the zero voltage vector output time may be a predetermined value or more without changing the relative proportions of the output times of the voltage vectors other than the zero voltage vector. Thus, high voltages above twice the DC bus bar voltage are suppressed. The three phases are controlled together.
