Abstract: The present invention relates to a method for designing a cycloidal gear tooth profile of a gear shift actuator, the method designing a profile to have a backlash through a change in the radius of a rolling circle of an internal or external tooth profile of a cycloidal gear, and thus enables the smooth engagement of internal teeth and external teeth, reduces the engagement range of the internal teeth and the external teeth to have excellent durability and enable power loss to be reduced, and enables the shape machining of the gear by using general cycloidal gear machining, thereby facilitating manufacturing and being capable of improving machining precision.

Abstract: The present disclosure relates to a surgical snare instrument that includes a tube having a hollow, an excising unit having a wire installed to be slidable along the hollow of the tube and a loop part installed at an end of the wire and inserted into one end of the tube to be tightened to excise a polyp, an advancing-and-retracting unit installed at the other end of the tube to make the wire advance or retract along the hollow of the tube, and a rotating unit installed adjacent to the one end of the tube and configured to rotate the loop part when the wire moves with respect to the tube.

Abstract: The car cleaner includes a collecting part having a collecting space to collect dust or foreign substances; a suction/discharge pipe of which one side is coupled with the collecting part to be in communication therewith, and which has a suction and spray nozzle configured to transfer the dust or the foreign substances in the car to the collecting part; a vacuum suction unit having a sucking part connected with the collecting part and a discharging part configured to discharge sucked air; an external air suction switching unit installed between the collecting part and the sucking part of the vacuum suction unit so that air in the collecting part or external air is selectively sucked into the sucking part; and a suction/discharge switching unit provided so that air discharged through the discharging part is discharged through the suction/discharge pipe.

Abstract: A control apparatus connected to a display apparatus is provided. The control apparatus includes a main board configured to generate a first control signal that controls the display apparatus; a light source driver configured to generate a second control signal that drives a light source of the display apparatus; a power supply configured to supply power to the display apparatus; and a serial transceiver configured to perform a serial communication with the display apparatus and transmit the first control signal, the second control signal, and the power to the display apparatus via the serial communication.

Abstract: An image display apparatus includes a camera configured to capture an image of a user's face, a display configured to display a video currently being reproduced in the image display apparatus, and a controller configured to detect a change in facial expression from the captured image of the user's face when entering a personal video recording (PVR) mode and when the change in facial expression is detected, to store the video to be reproduced from a first time point before a point in time at which the change in facial expression is detected to a second time point after the point in time at which the change in facial expression is detected.

Abstract: The present invention relates to a car cleaner, and more particularly, to a car cleaner which is capable of sucking dust with a strong suction force and discharging high pressure air with a strong blowing force.

Abstract: The present invention is on injection mold with cooling and heating passage which can form cooling and heating passage close to forming space in the inside of mold body and easily design cooling and heating passage in forming space with complicated trajectory. Injection mold with cooling and heating passage consists of lower mold and upper mold forming blowed forming space by combining said lower mold on the top of said lower mold, provided that said lower mold or said upper mold consists of mold body in which forming space is created on one side so that melted resin is injected and formed; connecting groove depressed towards said forming space from the opposite side of the side with said forming space created; and sealing kit which is inserted into said connecting groove in separation from the end of forming space of said connecting groove and creates cooling and heating passage 60) in said separated space.
