  • Patent number: 6240330
    Abstract: In current manufacturing practices, if a process results in a partial product which is outside its specification, it is either sent back to be reworked, or is scrapped. This results in unacceptable waste. The present invention comprises a method for minimizing this wasted work and materials, by corrective actions by subsequent processes. This approach is general, and is capable of correcting the effects of out-of-specs manufacturing process conditions, including the salvaging of partial product, thereby obviating the need for rework or scrap.

  • Patent number: 6183352
    Abstract: A first pump collects used slurry which is employed for a CMP technique. A new slurry supply device supplies new slurry having a concentration higher than a concentration of the used slurry, to the used slurry. A sensor measures a concentration of recycled slurry produced by mixing the used slurry with the new slurry. The new slurry supply device stops supplying the new slurry, in a case where the concentration which the sensor measures is equal to or above a predetermined value. A second pump supplies recycled slurry onto a polishing stage, after the used slurry is completely recycled.

    Abstract: In a connection part of vertical transfer registers with respect to a horizontal transfer register, transfer electrodes to which clocks &phgr;V1, &phgr;V2A, &phgr;V3A, &phgr;V2B, &phgr;V3B, and &phgr;V1A are applied are arranged in the cited order. In a horizontal transfer register 6, transfer is conducted by 3-phase clocks &phgr;H1A, ØH1B, and &phgr;H2. By activating clocks, signal charges of a channel denoted by A-A′ and channels equivalent thereto are first transferred to undersides of electrodes of &phgr;H1A of the horizontal transfer register. The signal charges are transferred in the rightward direction to underside of electrodes of &phgr;H1B. Subsequently, signal charges of a channel denoted by B-B′ and channels equivalent thereto are transferred to undersides of electrodes of &phgr;H1B of the horizontal transfer register, and mixed with the signal charges previously transferred.

  • Patent number: 6181454
    Abstract: In an optical receiver, a photodiode converts an optical digital input signal to an electrical signal which is fed into a differential amplifier to produce a pair of true and complementary output signals. The true output signal is received by a peak detector and the output of this peak detector is summed in a first adder with the complementary output of the differential amplifier. The true output of the amplifier is summed in a second adder with a predetermined constant voltage. Difference between the output signals of the first and second adders is detected and compared with a decision threshold to produce an output signal at one of two logical levels depending on whether the difference is higher or lower than the decision threshold. Preferably, a second peak detector having a substantially similar operating characteristic to that of the first peak detector is connected between the source of the predetermined constant voltage and the second adder.
