The “keiretsu” structuring of assembler-supplier relations historically enabled Japanese auto assemblers to remain lean and flexible while enjoying a level of control over supply akin to that of vertical integration. Yet there is much talk currently of breakdown in keiretsu networks. This paper examines some recent developments in Japanese parts supply(More)
The proposition that ties between home offices and branch plants constitute a form of metropolitan dominance is evaluated by examining the dependence of these two forms of manufacturing organization on selected characteristics of the 110 largest SMSAs. The predictor variables in the analysis are measures of industry composition, population size, and(More)
Purchase-supply relations in Japanese electronics are less close and cooperative than in the automobile industry and involve less formal knowledge sharing. Our interviews with a number of major Japanese electronics firms reveal that suppliers are less involved in manufacturers’ product development processes and are brought in at later stages. However, too(More)
Defects in undoped germanosilicate fibers have a profound effect on optical properties in the visible region of the spectrum. Photoexcitation of these defects can produce a refractive-index change, which in turn can be used for many useful purposes, including the formation of gratings and second-harmonic generation in fibers. The defects responsible for(More)
We have demonstrated an actively mode-locked Cr:LiSAF laser pumped by 659-nm radiation from an intracavity frequency-doubled diode-pumped Nd:YLF laser. The laser was tunable from 815 to 915 nm, and pulses of 30-ps duration at an average power of 3.5 mW were generated. With further development this all-solid-state system will be particularly suitable for the(More)
A mode-locked Nd:YLF laser is described, which uses two diode-pumped Nd:YLF rods and intracavity doubling in LiB(3)O(5) to give an all-solid-state source of high-beam-quality 659-nm red light suitable for pumping Kerr-lens-mode-locked Cr:LiSAF. Significant increases in the quantity of 659-nm light produced on active mode locking of the laser are(More)
