Publication number: 20240066663Abstract: A power tool includes an electric motor including multi-phase windings; and a control circuit for controlling the electric motor to rotate. The control circuit includes a driver circuit including multiple switching elements having multiple driving states to drive the electric motor to rotate; a parameter detection module for detecting an electrical parameter of the control circuit; and a controller for outputting a pulse-width modulation (PWM) control signal to control the driver circuit to change the multiple driving states. The controller is configured to change the absolute value of the variation of a duty cycle of the PWM control signal according to the electrical parameter to control a steady-state error of the electric motor running in a constant speed to be within a preset range.Type: ApplicationFiled: July 6, 2023Publication date: February 29, 2024Inventor: Zhen Xu

Publication number: 20240066664Abstract: The present disclosure relates to a pad surface cleaning system to be used with a conditioning module to condition a polishing surface of a polishing pad. The pad surface cleaning system may be used to spray the polishing surface with a high-pressure fluid spray to loosen debris from the polishing surface. The pad surface cleaning system may also be used to remove the loosened debris. Further, the pad surface cleaning system may isolate a conditioning disk from a polishing fluid to protect the conditioning disk from reacting with the polishing fluid.Type: ApplicationFiled: August 1, 2023Publication date: February 29, 2024Inventors: Shou-Sung CHANG, Hui CHEN, Haosheng WU, Jianshe TANG, Sidney P.

Publication number: 20240066667Abstract: An extendable pronged pair of mandibles device for removing animal nests includes a handle base having a top surface, a bottom surface, a pair of side surfaces, a shaft surface, and a button surface. A handle protrudes out from the bottom surface of the handle base. Additionally, a shaft protrudes out from the shaft surface of the handle base. The shaft has a tubular body for nesting an arm with a pair of mandibles having a plurality of teeth for providing grip upon an animal nest. The pair of mandibles further includes a non-magnetic variation for engaging with the animal nest and a magnetic variation for engaging with a plurality of magnetic elements. A trigger is positioned proximate to the handle of the handle base and is a lever being an actuator for the pair of mandibles when pulled towards the handle.Type: ApplicationFiled: August 25, 2022Publication date: February 29, 2024Inventor: Eric Smith

Publication number: 20240066668Abstract: A mandrel for holding and positioning an intraocular lens blank during manufacturing includes a shank portion having a central axis and a lens blank holding section configured to hold the lens blank. The holding section includes a central cavity formed concentrically with the central axis of the mandrel. Projections are formed on a surface of the central cavity and are configured to support a first surface of the lens blank at a fixed distance from the surface of the central cavity. A ring fits within a peripheral portion of the central cavity to hold a second opposing surface of the lens blank. A method for making an intraocular lens using the mandrel includes filling the space formed under the first surface of the lens with a liquid, such as water, freezing the liquid, and then machining and/or milling the second surface of the lens blank.Type: ApplicationFiled: October 19, 2023Publication date: February 29, 2024Applicant: Benz Research and Development Corp.Inventors: Patrick H.

Publication number: 20240066672Abstract: A driving tool has a configuration for preventing deviation of a driving posture of driving members from intended position during a use. The driving tool has a guide member supplied to a driving passage and a relief passage for an engagement portion of a driver to pass. The relief passage is therefore blocked by the guide member, stabilizing a driving posture of the driving member. The guide member is then pushed by a lowermost engagement portion of the driver so as to be retreaded from the relief passage, thereby allowing the engagement portion to move downward in the relief passage.Type: ApplicationFiled: July 27, 2023Publication date: February 29, 2024Applicant: MAKITA CORPORATIONInventors: Nobuyuki HOSHIYAMA, Masaya NAGAO
