Abstract: Utilization data of reserved virtual machine (VM) instances can be obtained from a cloud service provider. A refund recommendation comprising a first quantity of VM instances and a refund credit associated with the first quantity of VM instances can be generated based on the utilization data. A purchase recommendation comprising a second quantity of VM instances and a purchase cost associated with the second quantity of VM instances can be generated. An exchange transaction to return the first quantity of VM instances and purchase the second quantity of VM instances can be generated, where a net total of the exchange transaction is determined based on the refund credit and the purchase cost.

Abstract: An electronic device manufacturing system configured to receive, by a processor, input data reflecting a feature related to a manufacturing process of a substrate. The manufacturing system is further configured to train a machine-learning model based on the input data reflecting the feature. The manufacturing system is further configured to modify the machine-learning model in view of the virtual knob for the feature.

Abstract: Described herein are exemplary methods and apparatuses for etching a nitride layer disposed above a substrate to form trenches without micro-trenching in accordance with one embodiment. The method includes forming openings in a resist layer and one or more dielectric layers. The dielectric layers may be disposed on a hard mask layer (e.g., nitride, polysilicon). Next, the method includes etching openings in the hard mask layer disposed above a substrate layer without micro-trenching. The etching occurs in a process chamber during a main etch with a first process gas mixture having a fluorocarbon gas, a hydrofluorocarbon gas, and an oxygenating gas. Next, the method includes etching openings partially into the substrate without micro-trenching with a second process gas mixture during an over etch having the fluorocarbon gas, the hydrofluorocarbon gas, and the oxygenating gas.

Abstract: A tab mechanism adopted for a zipper slide has a connection member having a hanging portion connecting the zipper slide and a clamping portion downwardly extending from the hanging portion. A locking structure having a top end connects the clamping portion of the connection member and a bottom end for hanging an object. The locking structure includes a male buckle and a female buckle clamping on and detachable from the male buckle for easily hanging an identification card, a toy, a whistle, a cell phone, or similar objects to avoid loss and damage.

Abstract: A zip fastener top-end piece arrangement in which the top-end piece of the zipper tape is formed of a top block and a bottom block, the bottom block having a top recessed hole, the top block having a bottom springy hook, which is disengaged from the top recessed hole of the bottom block to open the passage between the top block and the bottom block for enabling the zipper slide to be coupled to the zipper tape, or hooked in the top recessed hole of the bottom block to close the passage between the top block and the bottom block-after installation of the zipper slide in the zipper tape.

Abstract: A zipper with multiple and alternate colors comprises a core and a plurality of zipper teeth. The core has multiple and alternate colors by printing, color transferring or color coverage. The pigmented core is subjected to a color fixing process.

Abstract: A zipper teeth and top stop arrangement includes a zipper tape, a row of teeth injection-molded on the zipper tape, a slide sliding on the row of teeth, and a top stop injection-molded on the zipper tape and space from a first tooth of the row of teeth by a gap for stopping the sliding from escaping out of engagement with the zipper tape, wherein the first tooth of the row of teeth has an upper tooth body and a lower tooth body respectively disposed at top and bottom side of the zipper tape, the upper tooth body having a backward opening and a springy free arm suspended between the backward opening and the gap to stop the slide from escaping out of engagement with the zipper tape, the springy free arm being forced downwards by the slide for enabling the slide to be moved into engagement with the zipper tape during installation, the lower tooth body having a sloping top edge sloping backwardly downwards for guiding the slide into engagement with the zipper tape during installation of the slide in the zipper ta

Abstract: A top stop and zipper teeth arrangement for a zipper in which the top stop has a sloping bottom edge smoothly curved inwards and sloping downwardly backwards and terminating in a downward bottom projection, the sloping bottom edge defining with the topmost edge of the first tooth of the row of teeth on the longitudinal side rib of the zipper tape a gap through which the slide of the zipper is insert into engagement with the zipper tape; the first tooth having a stop wall portion at a top side of a neck thereof for preventing an inside partition wall of the slide from being moved into engagement with the neck of the first tooth when the slide is pulled downwards.

Abstract: A zip-fastener in which the hollow lower face of each of the interlocking teeth, which are directly molded on the zipper tapes, has two recessed retaining portions at two opposite vertical lateral sides, top and bottom transverse thread grooves disposed at top and bottom sides and respectively connected between the recessed retaining portions, and stitches are sewn on zipper tapes around the recessed retaining portions and transverse thread grooves of each tooth to fixedly secure the teeth to the zipper tapes.

Abstract: A top stop integral with a zipper tape for a zipper, the top stop including an upper stop block having a front stop face and a rear stop projection, the rear stop projection and the front stop face being respectively stopped at a top edge of the slide of the zipper and one side of a partition wall inside the slide to prohibit the slide from escaping out of engagement with the row of teeth on the zipper tape, and a lower stop block having a connecting portion downwardly extended from the bottom edge thereof and connected to a top edge of a first tooth of the row of teeth on the zipper tape.

Abstract: A method for determining the completion of removal by plasma etching of phosphorus doped silicon dioxide from an underlying substrate.
