Grooved straight

Fig. 10.22 SEM micrograph of the 500 nm thick polysilicon bridge (straight line, center) that is the heart of the hotwire anemometer. The bridge crosses a 80 pm deep groove produced by a micro PS sacrificial layer. After [St6],...

Longitudinal groove weld includes straight and spiral seam. Criteria are not intended to apply to welds made in accordance with component standards recognized by the code (ref. ASME.B31.3 Table A1 and Table 326.1) however, alternative leak test requirements dictate that all component welds be examined (see code for specific requirements). 

Bends and bulges. If we overlook the ridges and grooves on their surfaces the DNA structures shown in Figs. 5-3 and 5-12 are straight rods. However, real DNA rods are crooked and may contain distinct bends. The... 

As a reference case, this straight channel design without any grooves was taken [44], In the following, one typical set of design specifications is given. 

Mixer 75 [M 75] Oblique, Straight-grooved Micro Mixer (I)... 

This device contains in a T-type micro channel oblique, straight grooves, termed slanted wells in the original publication (see Figure 1.156) [156], The grooves have the same purpose as given for the devices discussed below, namely to induce lateral transport to promote mixing. 

Mixer type Oblique, straight-grooved mixer Channel width at top and bottom, depth 72 pm, 28 pm, 31 pm... 

M 75] [P 66] 3-D twisting flow is found for a mixer design with an array of multiple obliquely oriented, straight grooves [44]. 

Three physical realizations of SLM modules have been reported they are based on spiral, flat, and HF extraction units, as presented in Figure 4.3. Where a porous FS membrane is the liquid support in an automated flowing SLM configuration, flat and spiral modules are usually used, in which, respectively, a straight and a spiral machined groove is made in the inner two surfaces of the unit blocks.66,67 When the membrane support is sandwiched between the two unit blocks, donor and acceptor channels are formed on either side of the membrane.
