Pin performance

Each pin should be assessed for the number of preprints required. In this particular example, the pins required 150 to 200 preprints before achieving [Pg.113]

The number of preprints that a particular pin requires will depend upon several parameters. First, a substrate that is hydrophilic may allow for increased wethng of the surface, thereby drawing out more liquid from the capillary, and more importantly, from the outside of the pin. The net effect would be a reduchon in the number of preprints. Depending upon the buffer, this might also reduce the effective capacity of the quill as well. [Pg.114]

A was nonvolatile. The pins dipped in Buffer B simply dried out and left salt deposits to block the tip of the pin, thus preventing the pin from printing. [Pg.115]

Designing an array is not a trivial task. In addition to the probes of interest, an array should include appropriate numbers of positive and negative control elements, such as housekeeping genes and controls that can be used to monitor the efficiency of important steps within the process. For example, you may wish to spike in internal standards that track recovery or labeling efficiency among different samples. It is also important to consider how you will print. How many replicates do you want Should these replicates be [Pg.115]

The important point is to be aware of the performance characferisfics of individual printing pins (or ink-jets) and how multiple pins match up. [Pg.116]


Fuel pin performance was changed by these assumptions to be as shown in Table XVII. [Pg.104]

Fuel pin performance codes for analyzing the steady state and transient conditions have been improved since 1984, with the data of PNC7DOE operational reliability testing program in EBR-II, etc. The modification of codes for annular fuel is emphasized. A three dimensional FEM code for an analysis of defected fuel pin behavior is modifying by PIE results of Run Beyond Cladding Breach (RBCB) pin. Development of nitride fel fuel performance code is also in progress. [Pg.156]

After densiftcation, external electrode termination and leads are attached for MLC capacitor components, and pin module assembly and IC chip joining is carried out for MLC packages. The devices are then tested to ensure performance and overall reflabiUty. [Pg.313]

The unusual resiHence of ionomers combined with ease of processing have resulted in widespread replacement of balata mbber as golf-ball covers. In order to obtain desirable backspin characteristics, low glass-transition ionomer compositions have been developed (10). Transparent coatings on bowling pins promote both longer life and improved playing performance. [Pg.408]

The physical structures of microchip assemblies usually contain a number of thin films in contact, each of which plays a separate role in the performance of the device. As an example, in one structure a silicon thin film would be contacted on one face by a copper rod which conducts away die heat generated during computer operations, and on the other face by an aluminium thin film which acts as a connector to other silicon films. This aluminium film is in turn in contact with a ceramic layer containing other thin film devices, and widr copper pins which plug into the circuit board. [Pg.219]

A new nose eone was obtained and initial maehining performed by die repair faeility. The nose eone is supported by six radial pins. The nose eone and inlet easing were sent to die main plant to ensure die pin hole loeations were properly positioned. Here, die inlet easing was assembled and oversized pin holes were drilled and reamed in die pieees. Pins made to fit die holes were also maehined. Repau maehining... [Pg.209]

The addition of tape, insulating sleeving, and pin spacing makes the final transformer much larger and higher in cost. This is because taping is a manual operation and takes a significant amount of time to perform. [Pg.53]

The design of the slope compensation circuit is almost fairly qualitative and may eventually need to be adjusted at the breadboard stage. To estimate how much additional ramp voltage is needed to keep the power supply stable, one performs the following equation. Aj is the gain or step-down influences of the transformers between the output and the current sense pin. [Pg.127]

There are very few synchronous buck controllers on the market that are not targeted to the -i-5 to 1.8 V microprocessor local regulator application (i.e., Vm of -1-12 V and Ki of -i-5 V). Also ICs that bring out enough functions to pins so that one may tailor its performance to the application. I threw out two entire product offerings from two major California companies (not to throw stones) and found only one part that fits my needs, the UC3580-3 from Unitrode/TI. [Pg.166]

It is current practice to select the rotary shoulder connection that provides the balanced bending fatigue resistance for the pin and the box. The pin and the box are equally strong in bending if the cross-section module of the box in its critical zone is 2.5 times greater than the cross-section module of the pin at its critical zone. These critical zones are shown in Figure 4-127. Section modulus ratios from 2.25 to 2.75 are considered to be very good and satisfactory performance has been experienced with ratios from 2.0 to 3.2 [39]. [Pg.722]

Check for box swell and/or pin stretch. These are indications of over-torquing, and their presence gready affects the future performance of the Joint. [Pg.765]

A seal that is wobbling on the shaft can also cause wear on the drive pins. Erratic wear on the face contact causes poor seal performance. [Pg.952]

With the increased speed and horsepower capabilities of modem chain drives, the role of lubrication has increased in importance. The precision roller chain is actually a series of connected journal bearings and it is essential that lubrication minimizes the metal-to-metal contact of the pin/bushing joints of the chain. Many factors affect lubrication performance and chain life including heat, improper lubrication, windage, contamination, and oil viscosity. [Pg.987]

Number of cavities, layout and size of cavities/runners/gates/cooling lines/side actions/knockout pins/etc. Relate layout to maximize proper performance of melt and cooling flow patterns to meet part performance requirements preengineer design to minimize wear and deformation of mold (use proper steels) lay out cooling lines to meet temperature to time cooling rate of plastics (particularly crystalline types). [Pg.171]

A review of the vast amt of work performed in the field of percussion primers reveals what is essentially an empirical approach to the development of both primer designs and priming mixts. It is recognized that a percussion primer must perform two vital functions (1) it must fire , ignite , or otherwise function when provided with the proper mechanical stimulus — a firing pin (with optimum contour to its striking end) and (2) it must perform its other function by which the flame , fire , or output will ignite the proplnt properly so as to provide the projectile with the specified velocity and within... [Pg.852]
