A high-throughput matching memory (MM) for a data-driven microprocessor is discussed. An MM can be constructed using a hashing memory. However, one of the biggest problems with hashing memory is the necessity for selective processing whenever hashed address conflicts occur. To eliminate this problem, the MM incorporated a small amount of associative memory (32 words×50 b) as well as the hashing memory (512 words×42 b). The matching operation is subdivided into three pipeline stages, all controlled by the elastic pipeline scheme. With this structure, an MM with a high throughput of 100-mega-access/s MM can be realized 相似文献

A simple and effective new technique has been demonstrated which improves markedly the chemical and electrical properties of heat-treated anodic oxide films on GaAs. This technique should facilitate the use of anodic oxides in innovative GaAs devices. 相似文献

Stress fields near crack tips in an elastic body can be specified by the stress intensity factors which are closely related to the stress singularities arising from the crack tips. These singularities, however, cannot be represented exactly by conventional finite element models. A new method for the analysis of stresses around cracks is proposed in this paper on the basis of the superposition of analytical and finite element solutions. This method is applied to several two-dimensional problems whose solutions are obtained analytically, and it is shown that their numerical results are in excellent agreement with analytical ones. Sufficiently accurate results can be obtained by the conventional finite element analysis with rather coarse mesh subdivision. Computational efforts are then considerably reduced compared with other methods. 相似文献

Microwave dielectric measurements were performed in the frequency range from 1 mHz up to 30 GHz using a time domain reflectometry (TDR) method for emulsions and gels. Flat-end sample cells have been used in the TDR measurement to contact a small spot of the surface of those viscoelastic and solid samples without any destruction. Relaxation processes due to various water structures were observed for these aqueous systems. Relaxation parameters thus obtained offer information about these water structures and amounts. The relaxation strength obtained from the high frequency process due to free water can be an adequate measure of water content in spite of some ambiguities for different water structures in some materials. Comparisons of actual water contents in emulsion with those estimated from the relaxation strength indicate that water structure is affected by the interaction between water and micelle. Unfreezable water observed in DNA gel under the freezing point consists of bound water and a fraction of free water. Bound water molecules are still unfreezable to keep the double helical structure of DNA, when the fraction of free water is frozen at lower temperatures. These water structures determine physical properties of moist materials. TDR measuring technique with the flat-end cell is effective to investigate water structures in viscoelastic moist materials and to evaluate physical properties and structures of complex molecular systems. 相似文献

The laboratory scale experiments for determining the influence on the distribution of phosphorus by.adding Al-containing component in melting furnace were conducted. It is found that the addition of Al-containing component in melting furnace increased the amount of phosphorus in slag phase. Thermodynamic analysis of the industrial sludge melting process with the addition of different Al-containing components was also carried out. The compositions of slag and the gas in three different zones in melting furnace were obtained. The results also demonstrate that increasing the mole ratio Al/P of charged materials is an effective way to fix more phosphorus in slap, which can help reduce the amount of H3PO4 precipitate from guy in the waste heat boiler later. 相似文献

A cDNA clone encoding trypsin (AG-T) was isolated from the pyloric ceca of cold-adapted fish, arabesque greenling (Pleurogrammus azonus). The cDNA was composed of 892 bp with an open reading frame of 729 bp at nucleotide positions 25–753. Similar to all the
known trypsin, the AG-T seemed to be synthesized as preproenzyme that contains a hydrophobic signal peptide, an activation
pentapeptide and a mature trypsin of 222 amino acid residues. The AG-T also completely conserved the major structural features
common to trypsin such as the catalytic triad (His57, Asp102, and Ser195), the obligatory Asp189 and twelve Cys residues.
On the other hand, the AG-T possessed the deletion of Tyr151 and substitution of Pro152 for Gly in the autolysis loop when
aligned with the sequence of tropical-zone fish and bovine trypsins. In addition, Val75 concerned in a combination with calcium
ion was exchanged for Ala in the AG-T, and the content of positively charged amino acid residues at the calcium-binding site
of the AG-T was three times higher than those of tropical-zone fish trypsins. Moreover, the ratio between charged and hydrophobic
amino acid residues in the N-terminal region of the AG-T was also higher than those of temperate-zone fish and tropical-zone fish trypsins. Such structural
properties of the AG-T would contribute to its low thermostability. 相似文献

This paper proposes and validates a system for measuring the flexed posture of the flexible mono-tread mobile track (FMT) using a flexible displacement sensor (FDS). The FMT proposed previously has a single track and vertebral structure. The flexed posture of the FMT determines its turning radius and direction; thus, knowing its posture is important. However, it is impossible to measure the shape of flexible mobile systems using sensors located internally, such as a rotary potentiometer, or located externally, such as a laser scanner. To solve the problem, we introduce the FDS to measure the flexed FMT shape. The sensor consists of two fixed electrodes, a sliding electrode, and a nylon string coated with carbon (NSCC). It works as a flexible potentiometer by moving the sliding electrode along the NSCC while maintaining electrical contact. The measurement system is implemented in a prototype of the FMT called RT02-WORMY and is validated in a series of experiments. 相似文献

Starch, whey or hemicellulosic waste can be used as a raw material for the industrial production of rare sugars. D-glucose from starch, whey and hemicellulose, D-galactose from whey, and D-xylose from hemicellulose are the main starting monosaccharides for production of rare sugars. We can produce all monosaccharides; tetroses, pentoses and hexoses, from these raw materials. This is achieved by using D-tagatose 3-epimerase, aldose isomerase, aldose reductase, and oxidoreductase enzymes or whole cells as biocatalysts. Bioproduction strategies for all rare sugars are illustrated using ring form structures given the name Izumoring. 相似文献

In this study, we evaluated the antibacterial activity of essential oil vapors against histamine-producing bacteria Morganella morganii NBRC3848 and Raultella planticola NBRC3317. We measured the minimum inhibitory dose (MID) of 14 essential oils towards these two strains. Allyl isothiocyanate (AIT) and salicylaldehyde (SA) vapors showed higher antibacterial activity than the other 12 essential oil vapors. Both AIT and SA vapors suppressed growth of total aerobic bacteria and histamine-producing bacteria in bigeye tuna and mackerel meat during storage at 12°C. These vapors also inhibited histamine accumulation in bigeye tuna meat and mackerel meat. Thus, application of AIT and SA vapors is effective for preventing increase of histamine-producing bacteria and histamine formation in fish meat. 相似文献
