Application of lost foam casting process in production

July 2009

The technology characteristic of lost foam casting was introduced, and the difference of sand casting and lost foam casting was analyzed. The production practice validated that lost foam casting process possesses advantages such as simple working procedure, high efficient, low cost and high quality of casting, and so on. The casting defects that easily occur in lost foam casting as well as the ... [Show full abstract] prevention measures were put forward, which offered valuable references for the application of lost foam casting in practical production.

Generalized SU(3) Nambu-Jona-Lasinio model

October 1990 · Nuclear Physics A

We present calculations of mesonic (quark-antiquark) modes in a generalized Nambu-Jona-Lasinio model with three quark flavours. The effective interaction between quarks is symmetric under chiral SU(3)L⊗ SU(3)R and incorporates a U(1)A-breaking six-point interaction as suggested by 't Hooft. We concentrate on the evaluation of masses and decay constants of pseudoscalar mesons, with special ... [Show full abstract] emphasis on the underlying symmetry breaking patterns. Scalar, vector and axial vector mesonic modes are also discussed.

Design, manufacturing and testing of gratings for synchrotron radiation

July 2001 · Nuclear Instruments and Methods in Physics Research Section A Accelerators Spectrometers Detectors and Associated Equipment

The grating is one of the most important components of a monochromator. Figure accuracy and microroughness of the substrate, accuracy of the groove pattern, shape and uniformity of the groove profiles, and the reflection coating are to be brought to the technological limits, if optimum performance is requested. Precise testing is as important as accurate manufacturing. Some new aspects for these ... [Show full abstract] topics are presented.

The effect of duty ratio in phase shift mask design

January 1994 · Microelectronic Engineering

In transmission phase shift mask, variety of linewidths can be obtained by changing the duty ratio (space to linewidth ratio) of line and space structures. It has been observed that besides the change in linewidth, it also shifts the resist patterns which is quite substantial for subhalf micron technology device design rules. A simulator named SIMPHAD has been developed to design the phase shift ... [Show full abstract] mask. Using this simulator, the change in linewidth and the pattern displacement error have been quantified for both full and partial transmission type phase shift masks under various exposure conditions and are discussed in detail.

May 2016 · Jurnal Dinamika Hukum

The pattern of the authority relation between head of local government and Secretary of local government in the promotion of Civil Servants lead into two pattern which are sub-ordination and coordination. Normatively, the position of Secretary is subordinate from Head of local government. Meanwhile, the pattern of coordination is a tiered pattern that puts Secretary as officials who provide ... [Show full abstract] recommendations of official candidate to Head of local government as the Trustees of the Local Employment Officer.Both of these relation creates superior position of Head of local government in the terms of promotion of civil servants. To create a proportional authority relation, it necessary pre-requisite form of commitment, orientation of human resources and the use of technology. On that basis, a mechanism must be created to limit the authority of the Head of local government by strengthening the system of merit-based technology.Keywords : position, authority, promotion of civil servants

[The analysis of high frequency tympanograms according to Vanhuyse]

February 1995 · Otolaryngologia polska. The Polish otolaryngology

The high frequency tympanograms interpretation in theoretical consideration was the main subject of this study. The normal patterns of tympanograms 678 Hz was described. The most typical pathological tympanograms was presented. The special attention was paid on high frequency tympanometry diagnostic value in the ossicular chain pathology and the surgical treatment influence.

Foreign trade, local protectionism and industrial location in China

March 2007 · Frontiers of Economics in China

In this paper, we find that, in China, geographical changes of industrial bases in the 1980s had led to a slight drop in the extent of specialization and location imbalance, but in 1990s the specialization and industry imbalance have further developed. The geographical advantage for trade has a significant impact on the location patterns, and the effects of local protectionism are confined to the ... [Show full abstract] hinterland in 1990s. The role of comparative advantage in shaping industry location is evident, and some predictions derived from new economic geography are partially supported.

Exploiting Virtual Patterns for Automatically Pruning the Search Space

October 2005 · Lecture Notes in Computer Science

A lot of works address the mining of patterns under constraints. The search space is reduced by taking advantage of pruning conditions on patterns, typically by using anti-monotone and monotone properties. In this paper, we introduce two virtual patterns in order to automatically deduce pruning conditions from any constraint coming from the primitive-based framework which gathers a large set of ... [Show full abstract] varied constraints. These virtual patterns enable us to provide negative and positive pruning conditions according to the generalization and the specialization of patterns. We show that these pruning conditions are monotone or anti-monotone and can be pushed into usual constraint mining algorithms. Experiments carried on several contexts show that our proposals improve the mining.
