I picked up a 1500W pure sine wave inverter that peaks at 3000W… though doesn’t run even 9A 120V motor on the 9A electric chainsaw I have.
But designing a new product to fulfill a purpose or a need is a lot different than designing one to beat everyone else. Corners are cut, compromises are made, and the end result suffers. Besides, Samsung’s relentless pursuit of “first” has rarely resulted in a product that people want. There was the Galaxy Gear smartwatch, which was a clunky, confusing mess; the original Galaxy Note, which was a behemoth of a handset with limited app support; the overpriced and buggy Galaxy S6 Edge with a whole cavalcade of features that didn’t last more than a year. Samsung prides itself on being first, and likes to remind us of that any chance it gets.
Customer-driven requirements mandated that the size and shape of the new laser-based system fit within the fixed envelope of the current heating systems. Laser energy delivered via fiber-coupled laser diodes were initially considered—these types of diodes deliver light from the semiconductor diode via a flexible passive-core fiber. To achieve the necessary optical energy distribution across the processing area, secondary optics would also be required. Given the volumetric constraints of the heat source and the desire for higher electrical-to-optical efficiency, the use of fiber-coupled laser diodes was rejected. Using attached micro-optics for collimation, free-space direct diodes provide the desired beam divergence while providing an electrical-to-optical efficiency over 60%. The final system design includes four tap-water cooled T6 diode stacks from Lasertel (Tucson, AZ)—the T6 laser diode heat source is shown in FIGURE 3. The T6 stacks were chosen because they were the only laser packages that would produce the power level required while fitting into the available physical space. The customized spacing between the bars was configured so that up to 2000W of optical power could be evenly distributed across the work surface. The electrical path was configured to allow each stack to be powered individually based on the number of prepreg tows being processed. The composite material temperature is actively monitored by the system and a closed-loop system controls the current to each diode, allowing for the power to be adjusted accordingly. The laser system delivers heat in a focused area and allows quick on/off operation.
Some researchers are experimenting with the formation of CNTs from ethylene. Supported catalysts (Fe, Co, Ni), containing either a single metal or a mixture of metals, seem to induce the growth of isolated SWNTs or SWNT bundles in the ethylene atmosphere. The production of SWNTs, as well as double-walled CNTs (DWNTs), on Mo and Mo-Fe alloy catalysts has also been demonstrated. CVD of carbon within the pores of a thin alumina template (called a membrane) with or without a Ni catalyst has been achieved. Ethylene was used with reaction temperatures of 545°C for Ni-catalyzed CVD, and 900°C for an uncatalyzed process. The resultant carbon nanostructures have open ends, with no caps.
If you’re expecting transparent aluminum to have all of those properties, you’ll be disappointed. Although she doesn’t identify the material specifically, the material [Jo] got to handle was most likley not a metal at all, but a ceramic called aluminum oxynitride, composed of equal parts aluminum, oxygen, and nitrogen and known by the chemical formula AlON.
Still maybe there’s a possibility, send a load of electrons from a point to a flat detection plate. Or perhaps better, from a point, to a point, but via an intermediate point in the field you’re measuring. I guess that would get complicated really quickly though, trying to steer an electron beam, then having an unknown magnetic field steer it as well, and detect where.
anyway – a hard to scratch and durable window/front lens would probably be very welcome in the RC FPV crowd if they didn’t cost an arm and a leg…
I got what you intend, thankyou for putting up.Woh I am glad to find this website through google. “Don’t be afraid of opposition. Remember, a kite rises against not with the wind.” by Hamilton Mabie.
I have been reading out a few of your stories and i can claim pretty clever stuff. I will surely bookmark your website.
Hawthorn (5854 College Ave.) is one of Oakland’s best destinations for well-crafted women’s clothing with an emphasis on local brands with sustainable production practices—such as Freda Salvador and Ali Golden—so you you’ll not only look good in the clothes, but feel good buying them, too. // If you walk by Bella Vita (5511 College Ave.), don’t mistake it for just a children’s boutique. While the cheery shop does sell clothing for little ones (along with artisan-made toys), Bella Vita also specializes in brightly printed jumpsuits, tops, skirts, and dresses that would make Zooey Deschanel proud. // Whimsy meets functionality at Atomic Garden (5453 College Ave.), where wood-hewn home goods and playful gifts fill the space. You’ll go in for the hand-carved serving spoons, gilded trays, and vibrant indigo pillows, and somehow find yourself leaving with a hammered metal bangle, hand-woven hat, or airy scarf. // Nathan and Co. (5636 College Ave.) is like your neighborhood Jonathan Adler but sassier. Office staples for the disgruntled worker? Check. Swear word-laden celebratory stationery for a recent promotion or engagement? You bet. An old-timey mug emblazoned with the word "wench"? We’re shocked you even asked. // Next door at Maison d’Etre (5640 College Ave.), the offerings is more home-focused, with colorful doormats, artisanal soaps, and expertly designed serveware that you’d be hard-pressed to find at big box stores. // A neighborhood mainstay since 1969, the Oakland location of Pegasus Books (5560 College Ave.) stocks new and used books as well as an impressive array of magazines.
It was amazing to see the vast variety of specialised machinery available and from so many different countries, although we did notice that there was a very large Italian representation. Many companies that were at the show do have ties with South Africa through agents, and it was great to see that we are up to date with technology and machinery, even though South Africa is a relatively small market. The interest in our market was clear from the numerous prompt emails we received on our return from the companies we visited at the exhibition.
Johan Kriel, Director of LK Plating Services This was my first visit to the EuroBlech show. I went there to specifically look at laser technology and eccentric presses. I was pleasantly surprised by all the laser machine exhibitors on show as I only knew about five manufacturers beforehand.
