An elongate display track device has front and rear segments. The front segment has sidewalls with vertical channels therein to receive arm to support a product identification panel. A detent in each channel engages the scalloped surface of the bottom portion an arm to adjust the vertical position of the product identification panel. A foot is connected to the rear segment to elevate the rear of the track to assist gravity feed.

The dispenser comprises an eductor for the drawing of a concentrate fluid from a liquid reservoir container into an input carrier fluid by means of the flow of the other fluid utilizing a venturi effect. In this dispenser the concentration of the concentrate fluid in the input fluid can be varied to differing preset amounts. The dispenser contains an elongated channel having an input for the input fluid and dispensing nozzle at an exit end for dispensing the chemical concentrate fluid in a diluted form. There is a transverse intersecting channel intermediate the input end and the exit end. The transverse intersecting channel has an insert that is moveable in the intersecting channel, apertures of the moveable insert being alignable with apertures in the transverse intersecting channel and the liquid reservoir container holding the concentrate fluid. One aperture is in alignment with the elongated channel and another aperture in alignment with a channel from the liquid reservoir container. The channels from the liquid reservoir container will have a plurality of various sized apertures to provide for the flow of differing amounts of chemical concentrate fluid into the input fluid at a given input fluid flow rate. This results in a product stream of the input fluid diluted to a set concentration. By adjusting the moveable insert in the transverse intersecting channel and/or the input fluid flow rate the concentration of the chemical concentrate in the product fluid is changed.

A power device package for containing, protecting and providing electrical contacts for a power transistor includes a top and bottom lead frames for directly no-bump attaching to the power transistor. The power transistor is attached to the bottom lead frame as a flip-chip with a source contact and a gate contact directly no-bumping attaching to the bottom lead frame. The power transistor has a bottom drain contact attaching to the top lead frame. The top lead frame further includes an extension for providing a bottom drain electrode substantially on a same side with the bottom lead frame. In a preferred embodiment, the power device package further includes a joint layer between device metal of source, gate or drain and top or bottom lead frame, through applying ultrasonic energy.

A magnetic recording transducer for use in a data storage device is described. The transducer has a main writer pole and magnetic shields adjacent to the main writer pole. The magnetic shields include a first plated soft ferromagnetic layer, a second plated soft ferromagnetic layer, and an antiferromagnetic coupling (AFC) trilayer between the first plated soft ferromagnetic layer and the second plated soft ferromagnetic layer. The AFC trilayer includes a first AFC layer of sputtered ferromagnetic material; a second AFC layer of a nonmagnetic antiferromagnetic exchange material, and a third AFC layer of sputtered ferromagnetic material. Shields with AFC trilayers in leading, side, and/or trailing shields, as well as between shields are provided. A method of fabricating is also provided.

Systems and methods for providing perpendicular magnetic writers having gradient magnetic moment side shields are provided. In one case, the system includes a pole having a leading edge and trailing edge, a leading shield positioned closer to the leading edge than the trailing edge, the leading shield having a leading shield moment, a trailing shield positioned closer to the trailing edge than the leading edge, the trailing shield having a trailing shield moment greater than the leading shield moment, and a side shield positioned along side of the pole, the side shield including a gradient magnetic moment progressing from a first side shield moment to a second side shield moment, where the first side shield moment is about equal to the leading shield moment, and where the second side shield moment is about equal to the trailing shield moment and positioned closer to the trailing shield than the leading shield.

A method for detecting unbalance in a 3-phase voltage signal includes sampling the signal over an observation widow to determine a set of observations, and detecting the unbalance of the signal based on a probability density function (pdf) of the set of observations.
摘要:
A method and system for fabricating a magnetic transducer are described. The magnetic transducer includes a pole and a nonmagnetic intermediate layer adjacent to the pole. The pole has a paddle and a pole tip including a plurality of sidewalls. The pole includes a first magnetic pole layer, at least one antiferromagnetic coupling (AFC) structure on the first magnetic pole layer, and a second magnetic pole layer on the AFC structure(s). At least a portion of the first magnetic pole layer resides on the sidewalls of the pole tip. The paddle has a paddle width in a track width direction. The pole tip has a pole tip width in a track width direction that is less than the paddle width.
