Contact cards

Sockets and slots on the motherboard are as plentiful and varied as processors. The three most popular are the Socket 5, Socket 7, and the Single Edge Contact Card (SECC). Socket 5 and Socket 7 CPU sockets are basically flat and have several rows of holes arranged in a square. The SECC connector is just another type of slot, but one that an Intel Pentium II or Pentium El-class processor can be inserted into (as shown in Eigure 2.8). To illustrate which socket type is used for which processors, examine Table 2.1. 

In the manufacture of smart cards, microprocessor chips, memory chips, EEPROMs or combinations in flip- chip configuration are electrically bonded onto the circuit card using anisotropic electrically conductive paste or film adhesive (see Chapter 1). Smart cards may be contact or contactless types. In contact cards, the electrical contacts of the card connect to a card reader when the card is inserted. Contactless cards transfer data in proximity to a reader (www.smartcard.gov) without physical contact. 

Water-sensitive papers are readily available in most countries and provide a convenient system for visually assessing spray drift performance. These papers are coated with bromoethyl blue, which turns from yellow to blue when contacted with water. " However, since any water can cause this change in color, care needs to be taken to prevent accidental exposure to sources of water other than the pesticide. Such cards do not work well under humid conditions, and are not appropriate for sampling droplets with diameter below 15 qm. Quantitative estimates of droplet size distributions must take account of the exponential increase in droplet volume as the droplet diameter increases. As droplets strike the paper, the liquid spreads over the surface and leaves a stain with a size that is dependent on the volume of the droplet. The apparent droplet size will be greater for large droplets than for small droplets, and the size determination must be corrected to avoid bias. 

When a droplet falling at a certain velocity impacts on an object, it will wet and spread through the surface if the contact angle is less than 90°. If the object is very thin, the droplet may all soak into it and the liquid may reach the other side that can be seen if the droplet contains a tracer dye. In a thick and porous Kromekote card,l507] a droplet spreads to form a circular stain with simultaneous absorption and penetration into the card. Kromekote cards have been used in forestry spray trials to collect pesticide droplets for...

The use of an alert card is not a specific regulatory requirement. However, in many clinical trials, it is appropriate that an alert card is given to subjects, particularly if they are outpatients. In an emergency, the alert card will identify that the subject is in a clinical trial and provide information on the nature of the clinical trial and whom to contact for information. The alert card should contain the sponsor s name and address (if appropriate), investigator s name, address and telephone number, with a 24-h contact number (the contact should have knowledge of the study and not just be an on-calT physician), the protocol number, the indication (perhaps modified to be more acceptable to the subject) and the subject s name and address and identification number. 

There is a 24 hour Freephone service available to all parts of the UK for advice and information on suspected adverse drug reactions contact the National Yellow Card Information Service at the MCA on 0800 731 6789.

To complement your resume and distinguish you from other applicants, have personal business cards printed with your contact information. These personal business cards should be included whenever you send a resume package and also with your thank-you notes. 

For under 30, basic business cards can be printed that provide your contact information, including ... 

The resolution of potentiometric transducers is dependent upon the construction of the resistance element. In the case of a wire-wound resistance, in order to obtain a high resistance in a small space, the resistance wire is wound on to a mandrel or card which is straight or formed into a circle or helix depending upon the motion of the contact. This limits the resolution of the transducer as the wiper moves from one wire to the next on the mandrel. The best resolution that can be obtained is about 0.01 per cent (see Section 6.10.1). Typical wire-wound potentiometers have strokes of between 0.0025 m and 0.5 m and rotational versions from about 10° of arc to 50 turns. An alternative often employed is the conductive plastic film element. This provides a continuous resistance element and thus, a zero resolution, but such elements suffer from a higher temperature coefficient of resistance. A more recent development is a combination of earlier types in which a conductive plastic coating is sprayed on to a wire-wound resistor. 

Ease of maintenance Poor—large number of contacts Poor if integrated circuits soldered Poor—several custom boards Good—few standard cards... 

The test under glass is carried out in the following manner A piece of the material is stretched on a wooden frame and covered with cardboard which is white on the upper face and black on that in contact with the sample and has a central hole about 8 cm. in diameter. The card is covered with glass and the whole exposed to the light in the open air but protected from the weather. 

System Control The control unit operates all the functions of the extractor. It is composed of a CRT, keyboard, contact closure outputs and inputs and nine control cards each with special functions. This unit requires almost no modification since its functions are highly specialized and the circuits are delicately assembled. The most important function to the user is its ability to interface with other instruments. This is done via the contact closures. Of primary use in our design is the contact closure which controls the event end output pulse. In the Suprex Model 50, this is contact closure B. This event end contact closure is the main interface in our design to other in-... 

Treatment On a new system, make sure fuse(s) were installed. If variable voltage, make sure the selection card is correctly positioned. New systems are often shipped with fuses in a bag. If fuse is broken, replace it and contact service. 

The entrance to the plant must be distinctly placarded with a permanent sign indicating the nature of the dangerous and hazardous materials in the factory, with the basic emergency response to each. The "UN number" for each should be indicated on the sign as well as the appropriate emergency and contact numbers for example, the UN number for TDI is UN 2078. Hazard information cards also should be available and sent with each load of isocyanate.
