摘要:
A high carbon content and high strength heat-treated steel rail including by weight 0.80-1.20% carbon, 0.20-1.20% silicon, 0.20-1.60% manganese, 0.15-1.20% chromium, 0.01-0.20% vanadium, 0.002-0.050% titanium, less than or equal to 0.030% phosphorus, less than or equal to 0.030% sulfur, less than or equal to 0.010% aluminum, less than or equal to 0.0100% nitrogen, and iron. The steel rail has excellent wear resistance and plasticity and can satisfy the requirement for overloading. A method for producing the steal rail by heating a slab to a heating temperature, multi-pass rolling, and accelerated cooling, wherein a maximum heating temperature (° C.) of said slab is equal to 1,400 minus 100[% C], [% C] representing the carbon content (wt. %) of said slab multiplied by 100.

The present invention provides a liquid crystal display panel. An Nth set of scan lines is disposed between two neighboring row of pixels. Each set of the scan lines comprises an upper scan line and a lower scan line. Gate electrodes of the thin film transistors in the neighboring row of pixels are alternatively coupled to the upper scan line and the lower scan line sequentially. An Nth data line is disposed between a 2N-1th column of pixels and a 2Nth column of pixels. The Nth data line is coupled to source electrodes of the thin film transistors of the neighboring 2N-1th column of pixels and 2Nth column of pixels.

摘要:
A localized collaboration of wireless communication enabled devices can be provided for sharing of information that is independent of external communications. A local hub can communicate with a remote hub and end users using one or more wireless communication points, and provide for uploading and downloading of collaborative information from the local hub by an end user device. The local hub wirelessly broadcasts a message that has contact information that allows a remote hub to wirelessly retrieve collaborative information from the local hub. The local hub can synchronize collaborative information with a remote hub, if present, by retrieving a remote version of collaborative information using the remote hub's broadcast contact information; comparing the remote version with a locally stored version, if present; updating the local version with differences between the remote version if the remote version is a desired; and creating a local version if one is not present.

A high pressure water cleaner with detachable water tank includes a water cleaner main unit having an internal hydraulic pump, a top receptacle and a feed water connector in the receptacle in communication with the hydraulic pump, and a water tank detachably insertable into the receptacle and lockable to the receptacle by a movable lock.
摘要:
Text messaging between cell phones, computer applications, and/or other communication devices has become a common means of communication. Because of the prevalence of text messaging, robust text message processing may be facilitated through text messaging pipelines. Accordingly, as provided herein, a text messaging pipeline may be configured according to a pipeline module list. The pipeline module list may be constructed through an online service wherein predefined pipeline modules and/or user defined pipeline modules may be selected to create the pipeline module list. The configured text messaging pipeline may provide customized text message processing. For example, a user may select a spam filter, a translator, and/or other pipeline modules to configure a text messaging pipeline. Text message workflow (e.g., SMS messages that are sent and/or received by a computer application associated with the text messaging pipeline) may be processed through the text messaging pipeline.
摘要:
A defect detection system for an extreme ultraviolet lithography mask comprises an extreme ultraviolet light source (1), extreme ultraviolet light transmission parts (2, 3), an extreme ultraviolet lithography mask (4), a photon sieve (6) and a collection (7) and analysis (8) system. Point light source beams emitted by the extreme ultraviolet light source (1) are focused on the extreme ultraviolet lithography mask (4) through the extreme ultraviolet light transmission parts (2, 3); the extreme ultraviolet lithography mask (4) emits scattered light and illuminates the photon sieve (6); and the photon sieve (6) forms a dark field image and transmits the same to the collection (7) and analysis (8) system. The defect detection system for the extreme ultraviolet photolithographic mask uses the photon sieve to replace a Schwarzchild objective, thereby realizing lower cost, relatively small size and high resolution.
摘要:
Techniques for generating a globally applicable taxonomy of e-commerce goods are described. According to various exemplary embodiments described herein, a taxonomy management system is configured to analyze item listing titles and user search queries in order to identify a set of globally applicable product types that serve as universal descriptors of the underlying things or objects that are the subject of an item listing or the likely user intended subject of a user search query. Such globally applicable product types are agnostic as to any specific product inventory or product category structure of an e-commerce website. After the taxonomy management system identifies product types, the taxonomy management system may incorporate the identified product types into a global product taxonomy that identifies the globally applicable product types.

A high pressure water cleaner with detachable water tank includes a water cleaner main unit having an internal hydraulic pump, a top receptacle and a feed water connector in the receptacle in communication with the hydraulic pump, and a water tank detachably insertable into the receptacle and lockable to the receptacle by a movable lock. Thus, the water cleaner main unit and the water tank can be used together or separately subject to different application requirements.
摘要:
Disclosed is a method, system, and computer program product for performing predictions for an electronic design. Embodiments of the invention allow the ability to efficiently update the model predictions at a later time once previously incomplete blocks are completed. Predictions can be efficiently updated after block designs are updated (e.g. after correcting problems detected from model predictions).
