Abstract: A flow splitting device for gas reverse circulation drilling, including: an upper joint for connecting with a double-wall drill pipe; an inner tube which is arranged in the upper joint and defines a first passageway in communication with an inner chamber of the double-wall drill pipe, a second passageway in communication with an annular space in the double-wall drill pipe formed between the inner tube and the upper joint; a lower joint, having an upper end fixedly connected with the upper joint and a lower end for connecting with a drill tool; and a flow guiding member provided between the upper joint and the lower joint. A flexible sealing mechanism is provided outside the upper joint. The flexible sealing mechanism extends radially outward relative to the upper joint and the lower joint to form a sealing contact with a wellbore wall.

Abstract: A method of forming a semiconductor structure includes: providing an initial substrate having a first region and a second region; forming a first substrate on the initial substrate; forming a first insulating layer on the first substrate; forming a second substrate on the first insulating layer; removing the second substrate in the second region to form a second insulating layer on the first insulating layer in the second region; and forming a plurality of passive devices on the second insulating layer in the second region and forming a plurality of active devices on the second substrate in the first region.

Abstract: Disclosed is an interference protection device and method for a hydraulic support and a cutting part of a shearer. The device includes: a plurality of dust-proof cases evenly and fixedly provided on a surface of one side of a hauling part of the shearer that faces away from a coal wall, and a dust-proof housing fixed on the hydraulic support. A first ultrasonic transducer and a flash lamp are fixedly provided in each dust-proof case, and a second ultrasonic transducer, a receiver, and a data processing module are fixedly provided in the dust-proof housing. The data processing module is electrically connected to the second ultrasonic transducer and the receiver separately, the first ultrasonic transducers and the flash lamps are all electrically connected to an external single-chip microcomputer, and the data processing module is electrically connected to a hydraulic support control computer.

Abstract: A system and method for remotely locating a communication error support for hydraulic supports. The system includes a control panel, a support controller, a data converter, and two support drivers of the same type. Each support driver has two bus interfaces. The control panel transmits a control command to the data converter in a form of a WiFi signal. The data converter converts the WiFi signal into a message signal and transmits the message signal to the support controller. The support controller transmits the control command to the two support drivers, respectively. The support drivers transmit the command through CANH twisted pairs and CANL twisted pairs. When a bus for transmitting the command of a certain node has an error, the support controller calculates the fault node according to a formula n = p ? t 8 ? m , and feeds back the fault node onto the control panel.

Abstract: A word alignment apparatus includes a word extracting portion that extracts each word from an example sentence and from a translation sentence thereof, an alignment calculator that calculates at least one of a similarity degree and an association degree between a word in a first language and that in a second language to perform an alignment between words respectively included in the example sentence in the first language and those included in the translation sentence thereof in the second language on the basis of a calculated value, and an optimization portion that optimizes the alignment by performing a bipartite graph matching.

Abstract: A networked mobile home surveillance system includes a home surveillance application running on a user device to access services on a home network and receive data from the home network. A home network gateway uses SIP messaging to allow communication of commands and data on the user device to and from a home networked device through bridging between SIP and a non-SIP protocol of the home network. A home surveillance service on the home network controls home networked remote devices used to monitor the home, and is subject to control by the application.
