The gate

The gates referred to above can be created in various ways. For example, suppose that the probe beam goes tlirough the sample, but only half of its physical width (in the sample) is crossed with the pump beam. Now, if we have two photodiodes, one can measure the intensify of the perturbed part of the probe beam, whilst the second measures the unperturbed part as a result of creating spatial gates, the two recorded output signals can be used to measure the... 

Step 8. The -type source and drain regions are created by As ion implantation. The As can penetrate the thin gate oxide, but not the thick field oxide or the polysihcon gate. The formation of the source and gate does not require a separate resist pattern, thus this technique is called self-aligning. 

Semiconductor control modules gate the thyristors, which switch cm rent to the motor field at the optimum motor speed and precise phase angle. This assures synchronizing with minimum system disturbance. On pull-out, the discharge resistor is reapplied and excitation is removed k> provide protection to the rotor winding, shaft, and external electrical system. The control resynchronizes the motor after the cause of pull-out i.n removed, if sufficient torque is available. The field is automatically applied if the motor synchronizes on reluctance torque. The control is calibrated at the factory and no field adjustment is required. The opti-... 

Solution Firstly it is necessary to determine the volume flow rate through the runners and gates. The total volume of the mnners, gates and cavities may be calculated as follows ... 

To get the pressure loss in the runners and gates. The flow rate in the long runner is (2/4, hence... 

The overall frequency of the top event is calculated by combining together the constituent probabilities and frequencies of the various events in the fault tree using the appropriate logical relationships described by the AND and OR gates (the detailed calculation is given in CCPS, 1989b). 

Consider the NAND gate. The NAND gate yields a T unless both input values equal 1 . If the value of either one of input lines is fixed at 1 , the gate is equivalent to the NOT operator i.e. the gate yields an output of T if the free input-line equals 0 and a 0 if the free input-line equals T . If we now use the NOT operator to complement the NAND operator input line, we obtain the AND operator. Since we have already observed that the set AND, NOT is universal, we have thus also shown that the NAND operator is, by itself, universal. ...

Weld line Weld or knit fines where two parts of a melt join while flowing into the mold cavity can result in problems. The quality of the weld depends on the temperature of the material at the weld point and the pressure present in the melt after flowing from the gate. The higher the temperature and pressure, the more complete the weld and the better the product performance and appearance. Bringing the material to the weld point at a higher temperature and pressure requires rapid filling of the mold cavity (Chapter 3, BASIC FEATURE, Weld Line).
