Embodiments of the present invention help to accomplish accurate and reliable clearance control. In one embodiment of the present invention, a disk drive device adjusts the clearance between a head element portion and a disk with a heater on a slider. The clearance control according to the present embodiment incorporates the variation in heater power efficiency in the clearance variation depending on the radial position. The clearance variation in a unit of heater power varies depending on the radial position. Taking account of the variation in the heater power efficiency in the thermal fly-height control (TFC) depending on the radial position in addition to the clearance variation between the head element portion and the disk caused by variation in fly-height or attitude, accomplishes more accurate TFC.

A computer-implemented method that simulates NPskew effects on a combination NFET (Negative Field Effect Transistor) / PFET (Positive Field Effect Transistor) semiconductor device using slew perturbations includes performing a timing test by a computing device, by: (1) evaluating perturb slews in Strong N / Weak P directions on the combination semiconductor device for a timing test result; (2) evaluation perturb slews in Weak N / Strong P directions on the combination semiconductor device for a timing test result; and (3) evaluating unperturbed slews in a balanced condition on the combination semiconductor device for a timing test result. After each test is performed, a determination is made as to which evaluation of the perturbed and unperturbed slews produces a most conservative timing test result for the combination semiconductor device. An NPskew effect adjusted timing test result is finally output based on determining the most conservative timing test result.

The concavities forming the group are arranged in concentric circles with respect to the rotation axis of the impeller. A first groove is formed in a first inner surface of the casing and extends from an upstream end to a downstream end in an area that faces one group of concavities. A second groove is formed in a second inner surface of the casing and extends from an upstream end to a downstream end in an area that faces the other group of concavities. A seal portion is formed in at least one of the first and second inner surfaces of the casing and formed by one layer or a plurality of layers of thin film.

An adjustable brassiere (100) having two cups (102,104) joined to each other, a back band (106, 108) and shoulder straps (110,112). The back band has two parts: a first back band (108) having a first end connected to the first brassiere cup and having a second free end, and a second back band (106) having a first end connected to the second brassiere cup and having a second free end. The second free end of the first back band is detachably connected to the second free end of the second back band. The first shoulder strap (110) has a first end connected to the first brassiere cup and has a second end connected to the first back band, and the second shoulder strap (112) has a first end connected to the second brassiere cup and has a second end connected to the second back band. Adjustable side fasteners (114) connect the first and second brassiere cups to the first and second back bands, and these are able to alter an angle between the first and second brassiere cups and the first and second back bands. In two or more adjustable front fasteners (116) incorporated along each of the first and second brassiere cups connect the first and second brassiere cups and the first and second shoulder straps. The adjustable side fasteners allow the size of the brassieres cups to be increased in volume by one size and the adjustable front fasteners allow the cups to rotate to increase in capacity once side fasteners have been adjusted. The wearer can thus adjust the effective cup size of the brassiere to allow for size fluctuations during pregnancy and / or breast-feeding.

A screw for injection molding provides a coaxial piston that allows the effective cross-sectional area of the screw to be varied during the injection cycle permitting small shot metering with relatively large diameter injection molding screws. The screw is positioned within the injector barrel of a injection molding assembly and includes a number of threads disposed around its outer surface configured to advance molten plastic to the front of the barrel. The screw further includes a central bore having a piston slidably received within the central bore. The plastic shot to be forced out through the nozzle of the injection molding assembly is controlled by movement of the piston within the screw.

A wear and / or friction reducing additive for a lubricating fluid in which the additive is a combination of a moderately hydrophilic single-phase compound and an anti-wear and / or anti-friction aqueous salt solution. The aqueous salt solution produces a coating on boundary layer surfaces. The lubricating fluid can be an emulsion-free hydrophobic oil, hydraulic fluid, antifreeze, or water. Preferably, the moderately hydrophilic single-phase compound is sulfonated castor oil and the aqueous salt solution additionally contains boric acid and zinc oxide. The emulsions produced by the aqueous salt solutions, the moderately hydrophilic single-phase compounds, or the combination thereof provide targeted boundary layer organizers that significantly enhance the anti-wear and / or anti-friction properties of the base lubricant by decreasing wear and / or friction of sliding and / or rolling surfaces at boundary layers.

Lubrication additives of the current invention require formation of emulsions in base lubricants, created with an aqueous salt solution plus a single-phase compound such that partitioning within the resulting emulsion provides thermodynamically targeted compounds for boundary layer organization thus establishing anti-friction and / or anti-wear. The single-phase compound is termed “boundary layer organizer”, abbreviated BLO. These emulsion-contained compounds energetically favor association with tribologic surfaces in accord with the Second Law of Thermodynamics, and will organize boundary layers on those surfaces in ways specific to the chemistry of the salt and BLO additives. In this way friction modifications may be provided by BLOs targeted to boundary layers via emulsions within lubricating fluids, wherein those lubricating fluids may be water-based or oil-based.
