Therefore, it is important for judging the performance and the safety of the product to understand the size of the defect and the position by the ultrasonic method quantitatively. And, the reliability of the product improves further by feeding back this ultrasonic wave information to the manufacturing process. 

On the other hand, the reliability of the product improves, too, if each state of the plasticity deformation, the creep deformation, and the diffusion joint in the solid phase diffusion bonding as the bonding process, is accurately understood, and the bonding process is controlled properly. 

And, the reliability of the product improves further by feeding back accurate ultrasonic wave information obtained here to the manufacturing process. 

Although acrylonitrile manufacture from propylene and ammonia was first patented in 1949 (30), it was not until 1959, when Sohio developed a catalyst capable of producing acrylonitrile with high selectivity, that commercial manufacture from propylene became economically viable (1). Production improvements over the past 30 years have stemmed largely from development of several generations of increasingly more efficient catalysts. These catalysts are multicomponent mixed metal oxides mostly based on bismuth—molybdenum oxide. Other types of catalysts that have been used commercially are based on iron—antimony oxide, uranium—antimony oxide, and tellurium-molybdenum oxide. 

A number of products designated GRAS are being scmtini2ed by the FDA because of advertisements and claims made by producers or manufacturers of these products. Statements that indicate that feeding such products improve animal performance may require substantive data to support such claims in the future.

In cases of all but intravenous adininistration, dosage forms must make the active moiety available for absorption, ie, for dmg release. This influences the bioavailabiUty and the dmg s pharmacokinetic profile. Ideally the dmg is made available to the blood for distribution and elimination at a rate equal to those processes. Through technological developments dmg product design can achieve release, absorption, and elimination rates resulting in durations of activity of 8—12 hours, ie, prolonged action/controlled release dmg products (21,22). Such products improve the compliance rate of dmg usage by patients. 

Seven of the tools of quahty have been summarized (43). The first tool is a flow chart, used to help understand the organizational flow of a procedure or process. A flow chart should be constmcted with the fiiU participation of the people who do the work. Its principal benefit is to enable teams, such as problem-solving or productivity improvement teams, to reach a common vision of the work flow. Its use enables the improvement effort to begin with this common understanding. Figure 3 contains an example for manufacture of a polymeric material. 

American Tire Reclamation, Inc. (Detroit, Michigan) plans to constmct a commercial-size plant to supply a refined version of carbon black and oil produced by pyrolysis of tires. The pyrolysis product improves aging and reduces mtting when added to asphalt (qv) (28). 

Do we have a quaUty process for rapid product development and market penetration Do we have a stream of product improvements Are we develop-ing common platforms for families of products (37) Are we developing improved processes concurrently with our new products How do we maintain our manufacturing processes at world-class levels (Fig. 5) (38) ... 

Initially, all of the SBR polymer known as GR-S produced during World War II was by the batch process. Later, it was thought that a higher volume of polymer would be needed for the war effort. The answer was found in switching from batchwise to continuous production. This was demonstrated in 1944 at the Houston, Texas, synthetic mbber plant operated by The Goodyear Tire Rubber Company. One line, consisting of 12 reactors, was lined up in a continuous mode, producing GR-S that was mote consistent than the batch-produced polymer (25). In addition to increased productivity, improved operation of the recovery of monomers resulted because of increased (20%) reactor capacity as well as consistent operation instead of up and down, as by batchwise polymerisation. 

Many companies provide support for both their research personnel and technical service personnel to participate in these types of activities. Even a pohcy of one conference per person per year, if appHed correctiy, provides a great deal of value to the individual and to the organization. The returns on this investment iaclude intangibles such as additional technical contacts and enhancement of the technical reputation of the company, as well as tangibles such as personnel possessing the latest information in their fields of endeavor, allowing them to better address customer concerns and needs, and developing ideas for process and product improvements. 

Celanese recently announced an expansion that will double its tow and flake capacity from 35,750 metric tons to 60,500 metric tons by 1994 (106). The increased capacity will be achieved through expansions and productivity improvements at the U.S., Belgium, Canada, Mexico, and China operation centers. 

The standard also requires opportunities for quality and productivity improvement to be identified and appropriate improvement projects implemented. 

A need for productivity improvement may arise because your standards were made difficult to achieve although possible to attain. As a result this has the effect of encouraging initiative and resourcefulness and using the capabilities of your personnel. Many improvement opportunities will be identified by those who are eager to seek easier ways of doing things.

Improved co-monomer incorporation. Metallocene catalysts are very efficient at co-monomer incorporation, which means that co-monomer use can be reduced by a factor of ten or more. This has some cost advantages but, more importantly, there is less unincorporated comonomer in the final product, improving efficiency and mass balance and reducing VOCs. 

Protoplast fusion induced by polyethyleneglycol and Ca was carried out between two auxotrophic mutants of Aspergillus sp. CH-Y-1043. The hybrids obtained showed significant differences in endopectinase activity and morphology compared to the prototrophic strain. Strains grown on lemon peel showed production improvement with respect to the parental strain. Since H15 hybrid showed up to 90% higher endopectinase production than the wild type CH-Y-1043, kinetics of enzyme production in Fernbach flasks and Fermentor (14L) by H15 were determined.
