Abstract: A semiconductor processing chamber may include a pedestal configured to support a substrate during a plasma-enhanced chemical-vapor deposition (PECVD) process that forms a film on a surface of the substrate. The chamber may also include one or more internal meshes embedded in the pedestal. The one or more internal meshes may be configured to deliver radio-frequency (RF) power to a plasma in the semiconductor processing chamber during the PECVD process. An outer diameter of the one or more internal meshes may be less that a diameter of the substrate. The chamber may further include an RF source configured to deliver the RF power to the one more internal meshes. This configuration may reduce arcing within the processing chamber.

Abstract: The present disclosure provides a driving module and a display device. The driving module includes a serial-parallel conversion circuit and a data providing circuit, the serial-parallel conversion circuit is configured to convert a serial input signal into a parallel output signal and generate a transmission control signal and a common electrode voltage signal in accordance with mode indication information carried by the parallel output signal, and the parallel output signal carries the mode indication information and input display data; and the data providing circuit is configured to convert the input display data into output display data and transmit the output display data to a corresponding data line under the control of the transmission control signal. According to the embodiments of the present disclosure, it is able to achieve display through relying on serial input signals and other signals provided by a system without a display chip.

Abstract: A shift register and a driving method therefor, a gate driving circuit and a display device are provided, wherein the shift register includes a pull-up control sub-circuit configured to provide a signal of a first signal terminal or a second signal terminal to a pull-up control node under control of a first input terminal and a second output terminal; the pull-down control sub-circuit is configured to provide a signal of a first power supply terminal or a second power supply terminal to a pull-down node under control of the pull-up control node, the first signal terminal, the second signal terminal, a first clock signal terminal and a second clock signal terminal; the output sub-circuit is configured to supply a signal of a third clock signal terminal to a first output terminal and a signal of a fourth clock signal terminal to the second output terminal.

Abstract: A visual ureteroscope includes a ureteroscope body and a ureteroscope tip. The ureteroscope tip includes a tip portion and an image capture device, wherein the tip portion is arranged at a front end of a ureteroscope tube of the ureteroscope body; the tip portion has a camera end face and an aspiration end face; the tip portion includes an aspiration hole, which is in communication with an aspiration channel of the ureteroscope body, and an operating hole for an operating component to pass therethrough, the aspiration hole axially extending forwards from the aspiration channel to the aspiration end face to form an aspiration opening, and the operating hole obliquely extending forwards such that the operating component that passes out from the operating hole, obliquely extends forwards to extend out of the tip portion; and the image capture device comprises a camera.

Abstract: Disclosed is an impact-during-suction surgical ureteroscope, comprising: a ureteroscope main body, an operating portion operably arranged in the ureteroscope main body, and a lithotripter. The ureteroscope main body comprises a ureteroscope structure main body and a suction channel extending from a front end to a rear end in the ureteroscope structure main body. The suction channel has a suction opening at the front end. The lithotripter is movably disposed in the ureteroscope structure main body so as to switch between a first state and a second state. When in the first state, a cutting head of the lithotripter extends out of the suction opening so as to impact a stone; when in the second state, the cutting head of the lithotripter is retracted into the suction opening and is used to impact crushed stones blocking the suction opening.

Abstract: A disposable gas lighter with advertising flashlight. The lighter has a flashlight unit having a power source, a lamp electrically connected to the power source, a push-button switch to turn on the lamp when pressed down, a sleeve installed in a recess of the body which contains the lamp in one end thereof, a film bearing advertising information and placed in around a middle portion of the sleeve, and a convex lens contained in a free end of the sleeve. The convex lens is located in an opening defined on the surface of the body. When the push-button switch is pressed down, the flashlight unit is able to give off a light beam. When the beam meets a plane in front of the gas lighter, a project of the film comes into being. Viewers then are able to watch the advertising information of the film with the project.

Abstract: A child resistant utility lighter having a handle, a barrel mounted in the handle and extending outward, a fuel tank within the handle and for containing liquefied gaseous fuel, a gas valve mounted on the fuel tank, a trigger being able to startup the piezoelectric unit to generate sparks for ignition, and, a lever rotatably mounted on the handle by a lever pin. The utility lighter further has a safe button slidably mounted on the handle and pushed by a first elastic element to an undepressed position; and, a piezoelectric unit contained in the handle and having a starting button, the piezoelectric unit constantly stops at a departure position in which the trigger, when pulled over, is not able to meet the piezoelectric unit, and being able to be pushed to an aligning position by depressing the safe button for ignition by pulling over the trigger.
