Title: Luminance signal generation circuit with single clamp in closed loop configuration and horizontal synchronization pulse generation
Inventor: NAYEBI MEHRDAD
IPC: H04N9/72
Filed: 1998-05-05
Granted: 2000-02-11
Abstract: A luminance signal generation circuit with single clamp and horizontal synchronization pulse generation circuit generates a separate luminance video signal Y, representing RGB input signals, and having a horizontal synchronization pulse. During a burst period, the single clamping circuit is enabled and compares the separate luminance signal Y to a reference signal. A difference signal, representing the difference between the separate luminance signal Y and the reference signal, is used to adjust a blanking level of the RGB input signals until the blanking level of the separate luminance signal Y is equal to the reference signal. During the non-burst periods, the single clamping circuit is disabled and a Y-matrix circuit combines the RGB input signals into the separate luminance signal Y. A horizontal synchronization pulse generation circuit generates a horizontal synchronization pulse to be added to the clamped separate luminance signal Y. During the horizontal synchronization period, a current is switched through a path resistor and used to generate the voltage level of the horizontal synchronization pulse. The voltage drop across the path resistor during the horizontal synchronization period is applied directly to the output video signal thereby generating a horizontal synchronization pulse. The current switched through the path resistor is generated by a voltage drop across a current resistor. The ratio of the path resistor to the current resistor is matched, allowing the required signal accuracy to be achieved in the voltage drop across the path resistor and generating the appropriate voltage drop across the path resistor according to the current flowing through the current resistor.

Granted: 2002-04-11
Abstract: In the electric power system protective control system, a plurality of protective control apparatuses each having a protective control function to an electric power system are distributed and connected through a communication network to each other so that data communication is permitted among the respective protective control apparatuses. Each of the protective control apparatuses is carried out a process of executing a control operation related to the protective control function of the own apparatus according to a program module. The program module migrates through the communication network to the own apparatus along a predetermined route of migration. Each of the protective control apparatuses executes a process of migrating the program module from the own apparatus to another protective control apparatus. The another protective control apparatus is determined to a next destination of migration according to the route of migration. In a case where the program module is not migrated by the migration process to the next destination protective control apparatus, each of the protective control apparatuses executes a process of changing a next destination of migration of the program module to a predetermined protective control apparatus except for the next destination protective control apparatus, making it possible to prevent the program module from stopping.

Title: Structure and method for improving low temperature copper reflow in semiconductor features
Inventor: DING PEIJUN
IPC: H01L21/203
Filed: 1999-11-17
Granted: 2001-07-11
Abstract: We have discovered that complete copper filling of semiconductor features such as trenches and vias, without the formation of trapped voids, can be accomplished using a copper reflow process when the unfilled portion of the feature structure prior to reflow comprises a capillary within the feature, wherein the volume of the capillary represents between about 20% and about 90%, preferably between about 20% and about 75% of the original feature volume prior to filling with copper. The aspect ratio of the capillary is preferably at least 1.5. The maximum opening dimension of the capillary is less than about 0.8 mu m. The preferred substrate temperature during the reflow process includes either a soak at an individual temperature or a temperature ramp-up or ramp-down where the substrate experiences a temperature within a range from about 300 DEG C about 600 DEG C, more preferably between about 300 DEG C and about 450 DEG C. By controlling the percentage of the volume of the feature which is unfilled at the time of the reflow process and taking advantage of the surface tension and capillary action when the aspect ratio of the feature is at least 1.5, the copper fill material is easily pulled into the feature which comprises the capillary without the formation of voids along the walls of the feature. The preferred method of application of the last layer of copper prior to reflow (the layer of copper which produces the unfilled capillary within the feature) is electroplating, although CVD or evaporation or other conformal layer formation techniques may be used.
