Abstract: A reactor system and method for catalytic dehydrogenation of saturated C3-C6 hydrocarbons within a reactor placed within a reactor disengager, where the reactor is open at the bottom thereof and open to the disengager, and the exit riser from the reactor is not hard coupled to at least one downstream cyclone. This configuration permits controlling the amount of catalyst within the reactor by varying the level of catalyst in the reactor disengager outside the reactor and permits controlling total catalyst hold-up and/or weight hourly space velocity (WHSV) independently from catalyst flow from the catalyst regenerator.

Abstract: Machine vision devices may be configured to automatically connect to a remote management server (e.g., a “cloud”-based management server), and may offload and/or communicate images and analyses to the remote management server via wired or wireless communications. The machine vision devices may further communicate with the management server, user computing devices, and/or human machine interface devices, e.g., to provide remote access to the machine vision device, provide real-time information from the machine vision device, receive configurations/updates, provide interactive graphical user interfaces, and/or the like.

Abstract: A magnetoresistive sensor (10) having permanent magnet stabilization includes a magnetoresistive layer (12), at least one permanent magnet (14a or 14b), and first and second current contacts (16a and 16b). The magnetoresistive layer (12) has an active sensing region (18) having a first thickness, and at least one under layer region (26a or 26b), with each under layer region (26a or 26b) having a second thickness that is less than the first thickness. Each permanent magnet (14a or 14b) is formed upon an under layer region (26a or 26b) of the magnetoresistive layer (12), and the first and second contacts (16a and 16b) are electrically coupled to the active region (18).

Abstract: In a thin film magnetic head comprising a magnetoresistive sensing element (MRE) located inwardly from the head face, a first section of a broken flux guide extending inwardly from the head face to overlie one peripheral edge portion of the MRE, and a second section overlying an opposite peripheral edge portion of the MRE, the space overlying the MRE between the flux guide sections is filled with a poller such as a photoresist, providing a smooth surface for a test/bias conductor, reducing shorts due to inadequate step coverage, and providing mechanical stress relief, leading to improved stability of the MRE.

Abstract: In a method of manufacturing a thin film magnetic head having aligned top and bottom pole tip pieces, a sacrificial mask protects the upper pole tip while the exposed non-aligned portions of the gap material and lower pole tip are removed. The sacrificial mask is deposited using a self alignment technique.

Abstract: A vertical recording head includes a W-shaped core, a substrate carrying a thin film probe supported in one slot of the core, and a shield coil wound in the slots to hold the substrate and assemblage together. A non-magnetic cap forms the surface of the head over the cap, with the arrangement being such that the probe extends through the cap so the magnetic gap is as small as possible.

Abstract: A process for fabricating a negative pressure slider is disclosed which briefly comprises the steps of: (a) applying a dry negative photoresist layer to the surface of the slider; (b) positioning a mask having alignment marks which are too narrow to be resolved during exposure and development to pattern the photoresist layer to expose the portions of the flying surface of the slider to be milled by an ion milling process; (c) ion milling the slider wherein the patterned photoresist layer protects the flying surface of the slider while the negative pressure cavities of the slider are being milled; and (d) removing the remaining portions of the photoresist layer once the negative pressure cavities have been milled.

Abstract: A magnetic head is manufactured by depositing a layer of spacer material onto the facing surfaces of the magnetic cores; the thickness of each layer being approximately one-half the length of the intended gap and the thicknesses of both layers together being approximately equal to the thickness (length) of the gap. A layer of bonding glass is deposited onto the surfaces of the spacer layers and the cores are pressed together at an elevated temperature to fuse the glass layers and extrude most of the glass.

Abstract: A grid system for an ion beam generator is provided having a frustoconical shape so that the collimated ion beam converges at a predetermined angle toward the target to provide selective beveled etching.
