Fundamentals of Die Casting Design.pdf

November 7, 2009 · Filed Under Mechanical & Industrial Engineering · Comment  · Tags: , , , ,

Taken from Abstract: Die-casting engineers have to compete not only with other die-casting companies, but also against other industries such as plastics, and composite materials. Clearly, the ”black art” approach, which has been an inseparable part of the engineer’s tools, is in need of being replaced by a scientific approach. Excuses that “science has not and never will work” need to be replaced with “science does work”. All technologies developed in recent years are described in a clear, simple manner in this book. All the errors of the old models and the violations of physical laws are shown. For example, the “common” pQ2 diagram violates many physical laws, such as the first and second laws of thermodynamics. Furthermore, the “common” pQ2 diagram produces trends that are the opposite of reality, which are described in this book.
The die casting engineer’s job is to produce maximum profits for the company.
In order to achieve this aim, the engineer must design high quality products at a minimum cost. Thus, understanding the economics of the die casting design and process are essential. These are described in mathematical form for the first time in this volume. Many new concepts and ideas are also introduced. For instance, how to minimize the scrap/cost due to the runner system, and what size of die casting machine is appropriate for a specific project.
The die-casting industry is undergoing a revolution, and this book is part of it. One reason (if one reason can describe the situation) companies such as Doehler Jorvis (the biggest die caster in the world) and Shelby are going bankrupt is that they do not know how to calculate and reduce their production costs. It is my hope that die-casters will turn such situations around by using the technologies presented in this book. I believe this is the only way to keep the die casting professionals and the industry itself, from being “left in the dust.”

The Intel StrongARM* SA-1110 Microprocessor (SA-1110) is a highly integrated communications microcontroller that incorporates a 32-bit StrongARM RISC processor core, system support logic, multiple communication channels, an LCD controller, a memory and PCMCIA controller, and general-purpose I/O ports.As do the Intel StrongARM SA-110 Microprocessor (SA-110) and Intel StrongARM SA-1100 Microprocessor (SA-1100), earlier members of the StrongARM family, the SA-1110 provides power efficiency, low cost, and high performance. Figure 1-1 shows the features of the SA-1110. The shaded boxes are features that have carried over with few or no changes from the SA-110. The nonshaded boxes are new or updated features for the SA-1110; most of the features are equivalent to that of the SA-1100. The SA-1110 differs from the SA-1100 only in the features of its memory and PCMCIA controller.

Technical Notes on the EEC-IV MCU.pdf

February 2, 2009 · Filed Under Others · Comment  · Tags: ,

The EEC-IV design began in 1978 and was first introduced in 1983 in the 1.6L Escort, Lynx, EXP and LN7 cars. It has gone through several major physical changes, the earliest using a fairly simple two board design with through hole soldered components while the last are more current in technology, showing extensive use of surface mount components and a much more finished and complex appearance. In between, there appears to be a variety of mother/daughter board and other designs. Still, they are all called EEC-IV, although somewhere in its life there was a Ford P/N generational change.

Intel 8031 is the most popular and most used architecure in the 8 bit segment, it also can be found in a variety of configurations, flavour and you just cannot see this kind of variations with any other architecture, even after 25 years of existence, semiconductor manufacturers still come out with somekind of device useing thins 8031 core.
