  • Patent number: 10868495
    Abstract: Some aspects of the present disclosure relate to an apparatus, a PLL and an electronic device. The apparatus comprises a voltage-to-current (V2I) converter, a current controlled oscillator and a compensation current. The V2I converter is operable to receive a first voltage and generate a first current based on the first voltage. The current controlled oscillator is coupled to the V2I converter and operable to generate an oscillation signal based on a second current from or to the V2I converter. The compensation circuit is coupled to the V2I converter and operable to receive a third current from or to the V2I converter. The second and third currents vary in response to at least one of temperature variation and supply voltage variation of the apparatus. Variation direction of the third current is opposite to variation direction of the second current and different frequencies may be provided for a low supply voltage domain.

  • Patent number: 7429281
    Abstract: A method for manufacturing bio-diesel oil in the present invention uses single-carbon alkane compounds to reform into intermediate alkanes to achieve a synthetic alkylation matter. The synthetic alkylation matter is mixed with plant oil or mixed with alkyl fatty acid derivative from fatty acid of the plant oil into a mixture. Additionally, additives such stabilizer, preservatives, etc.

  • Patent number: 7206653
    Abstract: Computer-implemented wafer-based planning methods for batch-based processing tools. Tool groups are appended in a tool group level of planning data provided by a MES for converting planning data from batch-based to wafer-based data. The planning data with appended tool group is applied to dispatch processing tools.

  • Patent number: 7127314
    Abstract: System and method for monitoring a fabrication process. Generally, an actual-to-planned variance is calculated by determining a daily part index as a percentage of the delta between the planned quantity and the actual quantity over the planned quantity. A weekly part index is calculated by averaging the daily part index over a predetermined time period. From the weekly part index, a site index is determined that takes into account products fabricated at a particular site. Furthermore, a planned-to-actual variance may be calculated by determining a daily part index as a percentage of the delta between the planned quantity and the actual quantity over the actual quantity. A weekly part index is calculated by averaging the daily part index over a predetermined time period. From the weekly part index, a site index is determined that takes into account products fabricated at a particular site.

  • Patent number: 6920366
    Abstract: A computer integrated manufacturing system executes a program process that performs a capacity planning method that allocates usage of a plurality of manufacturing elements of a manufacturing enterprise by major and minor apparatus, squeezing for overhead cost consideration, and site balance for maintain basic operation. The program process begins by receiving at least one fabrication forecast describing scheduling and types of product lots that are predicted to be fabricated within a first period of time by the manufacturing enterprise from at least one order management system of the manufacturing enterprise. Rolling statistics of products lots fabricated during a second period of time are retrieved from a data retention device of the computer integrated manufacturing system. Capacity planning for the allocation of the product lot predicted to be fabricated by the manufacturing elements is performed.
