Abstract:
A manufacturing method of flash memory. A substrate is provided, on which a gate structure is formed. A first spacer is formed on the sidewalls of the gate structure. A source region is formed in the substrate at one side of the gate structure. A first conductive layer and a sacrificial layer are formed on the substrate. The first conductive layer and the sacrificial layer are removed until the gate structure is exposed. A thermal oxidation process is performed to form a mask layer on the first conductive layer and the gate structure. The sacrificial layer remaining on the first conductive layer is removed, and the first conductive layer is etched with a square shape. The mask layer is removed, and a second spacer is formed on the sidewalls of the second conductive layer. A drain region is formed in the substrate at one side of the conductive layer.
Abstract:
A linear guide way structure. The structure utilizes spring strips to combine a sliding body assembly and end caps, instead of using screws or pins. The sliding body assembly and the end caps are combined together with an almost constant resilient force provided by the spring strips whose mechanical strength is greater than that of plastic material. The problem of exfoliation between two physically different materials such a metal and plastic never is avoided. Accordingly, the linear guide way is easy to fabricate, operate, and maintain with low cost.
Abstract:
A linear guide way structure comprises a guide rail, a slider, and two end cups. The slider has two ends each defining a ball return hole having a first-end-opening, and a ball groove having a second-end-opening. The adjustable end cup is provided with two ball direction changing paths each having a first-mating-end-opening abutting the first-end-opening of the ball return hole, and a second-mating-end-opening abutting the second-end-opening of the ball groove. The adjustable end cup is provided with a plurality of adjusting slits, and at least one of the adjusting slits has a determined depth so that the adjustable end cup is made flexible, thereby adjusting the distance between the two first-mating-end-openings of each of the two ball direction changing paths of the adjustable end cup, so that the first-mating-end-opening can be exactly engaged with the first-end-opening of the ball return hole.
Abstract:
A linear guide apparatus with magnetic distance sensor is disclosed. A magnetic tape is adhered right on the upper surface of the guide rail so as to minimize the variation of distance between the magnetic tape and a magnetic induction element to assure high distance sensing sensitivity when the slide block is exerted by a transverse thrust force. The magnetic tape can be adhered to the upper surface of the guide rail after the guide rail has been assembled to its base thereby facilitating the assembly work. The magnetic induction element is installed in an end cap of the slide block so that it is not necessary to modify the construction of the inner part of the slide block. As a result, the space is saved and the mechanical strength of the apparatus is increased. In order to reduce the influence of magnetic field induced by the electric current flowing in the power supply lines of the apparatus on the sensor signal, an outlet terminal block is provided on a side surface of the slide block so as to prevent the signal wires from passing through right over the magnetic tape thereby protecting the sensor signal from interference.

A proxy server and a hierarchical network system and a distributed workload management method. According to one embodiment of this disclosure, the proxy server includes: a rate controller configured to, based on measured request-related information and service quality parameters relative to service levels of requests, periodically determine a dispatch rate for requests of each service level, wherein the sum of the dispatch rate for respective service levels is less than or equal to a predetermined rate; and a request dispatcher configured to dispatch the requests of the corresponding service level in accordance with the dispatch rate determined by the rate controller. One aspect of the disclosure realizes a low overhead, highly scalable, simple and efficient workload management system to achieve QoS assurance and overload protection.
Abstract:
A corrosion-resistant granular magnetic recording medium with improved recording performance comprises a non-magnetic substrate having a surface; and a layer stack on the substrate surface, including, in order from the surface: a granular magnetic recording layer; an intermediate magnetic de-coupling layer; and a corrosion preventing magnetic cap layer. The intermediate magnetic de-coupling layer has an optimal thickness and/or composition for: (1) promoting magnetic exchange de-coupling between the granular magnetic recording layer and the magnetic cap layer; and (2) reducing the dynamic closure field (Hcl) for determining writeability and eraseability of the medium. Grain boundaries of the magnetic cap layer are substantially oxide-free, and have a greater density and lower average porosity and surface roughness than those of the granular magnetic recording layer.

Abstract:
A method for determining a suspect memory leak, including: sampling the throughput and memory usage of an application server; based on the sampled throughput, monitoring whether the throughput decrease continually, and based on the sampled memory usage, monitoring whether the memory usage remains stable within a predefined range; in response to a continual decrease of the throughput and the memory usage remaining stable within the predetermined range, determining that the application server is suspected of having a memory leak. Using the solution of the present invention can free an administrator of the burden of artificially identifying suspect servers, can identify a suspect server during runtime and further determine whether it actually has a memory leak.
