Family of parts

Cellular manufacturing—A manufacturing process that produces families of parts within a single line or cell of machines operated by machinists who work only within the line or cell. 

Another popular use of a multiple-tool holder is to provide the hole sizes common to a family of parts for tapped holes or for a standard series of electric knockouts. A 30-station multiple-tool holder, for example, could be equipped with an array of alpha and numeric characters to put part numbers or names on... 

Cellular manufacturing A manufacturing process that produces families of parts within a single line or cell of machines with operators who work only within the line or cell. The cellular concept is also applicable to administrative and technical process. In this context, it means clustering unlike operations to increase processing velocity. 

For larger cell arrays, the Maxim Integrated MAXllOSx family of parts provides a selectable cell monitoring function. 

Over the long history of TTL, a number of variants have been produced to achieve faster speeds, lower power consumption, or both. For example, the 54/74L family of parts incorporated redesigned internal circuitry using higher resistance values to lower the supply current, reducing power consumption to a Httle as 1/10 that of standard TTL. Speed was reduced as well, with delay times as much as three times longer. Conversely, the 54/74H family offered higher speeds than standard TTL, at the expense of increased power consumption. Both of these TTL families are obsolete, their places taken by various forms of Schottky TTL.

Up to now, we have reflected upon a family of partly competing and partly complementary theses about the metaphysics of the mind, and on how these theses can be illustrated by reference to the explication of reduction. These theses remain silent about the epistemic or procedural character of reductions (except for the highly implausible idea that the relevant identity-statements express a priori tmths) and about explanatory aspects of reduction. In the philosophy of mind, the dominant view about the link between reduction and explanation is that functional reduction somehow goes together with functional or mechanistic explanation. Functionalism also yields a theory of the metaphysics of mental properties and, contrary to ordinary type-identity theories, it explicitly employs the term reduction . 

Many authors, among whom the authors of the following chapters of this volume, have addressed the relevance of various aspects of topology in chemistry (see for example Ayers et al. [25]). From the abstract mathematical standpoint, however, a topology is defined within the framework of set theory given a set X, a topology T on X is a family of parts of X, called m open sets, i.e. a subset of P X) = 2, such that ... 

Level I comprises the exterior base plates and clamps that never change for a family of parts with the same overall maximum dimensions. 

ASTM-compliant mechanical test specimens were injection molded in a family tool from each resin and blend in Table 1. A set of specimens is considered to be 30-35 families of parts. Sufficient sets of each material were produced for one to be left unirradiated and three sets to be irradiated with either Co y, EB or X-ray at doses of 25, 50, 75, and 100 kGy. The sets of specimens were marked with the corresponding irradiation source and dosage and sent to Radiation Dynamics Incorporated in Edgewood, New York for irradiation. A 3 MeV RDI, 90 kW Dynamitron accelerator was used for the EB and X-ray radiation. The EB dose-rate was 100 kGy/second the X-ray dose-rate was 5.6 kGy/minute (3.3 x 10 kGy/second) For the y irradiation, materials were sent to a commercial gamma service facility which irradiated the PP at a dose-rate of 10 kGy/hour (2.8 x 10 kGy/second). Thus the relative irradiation dose-rates for the three methods were about 36,000 34 1 for EB X-ray y.
