    摘要： A system and method is provided for controlling clock skew to meet timing constraints for a semiconductor integrated circuit. On-chip self-tuning circuits can be connected to each latch in the integrated circuit for controlling clock skew. Each self-tuning circuit delays a clock signal that is input to a latch when the clock skew does not satisfy the timing constraint for that latch. The self-tuning circuit repeatedly delays the clock signal until the clock skew is satisfied or until the delay becomes greater than or equal to a predetermined threshold. The delayed clock signal is then pushed to other latches in the integrated circuit until all the timing constraints for the integrated circuit are satisfied.

    摘要： The present invention provides a method of fabricating an electronic component, using a tool for pressing a chip against a substrate and heating the same, connecting a chip electrode and a substrate electrode together via a bump, placing the substrate in alignment with a die alignment plane for an upper die and a lower die, clamping the upper die and the lower die to form a cavity and exhausting the cavity via an exhaust hole to evacuate the same, and injecting melted resin into the cavity and curing the melted resin to provide sealing resin. Then, in a predetermined ambient at a predetermined temperature the substrate is pressed against a test board and a predetermined electrical signal is applied from the test board via an external electrode to the chip to test an operation of an electronic component configured on a unit region of the substrate and the chip. Thereafter, cutting along a virtual line completes the electronic component. Thus, a plurality of chips can be resin-sealed collectively with high precision and a plurality of electronic components can be burnt in. As a result, in mounting the chip to the substrate, sealing the same with resin and burning in the same to provide an electronic component, the electronic component can be efficiently fabricated, with the sealing resin having a dimension with high precision.

    摘要： An improved magnus measuring apparatus for providing an automatic initial setting at high speed in testing a plurality of biological specimens which moves elastically with beats, wherein a tensile force is applied on a specimen by moving the transducer connected thereto with use of a motor to be driven and stopped under the control of a control unit, and thereby the rotating speed of the motor is increased gradually at least for a predetermined period of time from the start and then kept at high speed for bringing a bottom value of the tensile force to enter an extent of preliminarily set initial value. In another aspect of the invention, a detected tensile force is sampled for detecting a peak of the tensile force and a threshold value is renewed in succession from the initial setting based on detected peak and bottom values, and then detecting a peak of the tensile force being caused from the beats of the specimen, hence said tensioning is so controlled as to adjust the detected bottom value to be in an extent of preset tensile force.
