Abstract: A general engine throttle apparatus includes a throttle body 12, a throttle valve 13, a throttle shaft 14, a driven gear 24, an electrically driven motor 15, and a detected body block 26. The throttle valve 13 opens and closes an intake air introduction hole 11. The throttle shaft 14 holds the throttle valve 13 and is rotatably supported by a holding hole 16 of the throttle body 12. The electrically driven motor 15 transmits a rotation operation force to the driven gear 24. The detected body block 26 is attached to another end part in an axial direction of the throttle shaft 14, and a state of the throttle shaft 14 is detected by a sensor. The driven gear 24 is integrally formed on one end side in the axial direction of the throttle shaft 14. The detected body block 26 is formed to have a maximum outer diameter that is smaller than a minimum inner diameter of the holding hole 16.

Abstract: Provided herein is a method for detecting landing quality of an aircraft. Method steps include using an aircraft data system to determine whether a vertical speed rate is greater than a first preset value when the aircraft lands; determine whether a vertical acceleration is greater than a second preset value if the vertical speed rate is not greater than the first preset value when the aircraft lands; collect landing data; generate a landing message based on the collected landing data; store or transmit the landing message; and determine the landing quality based on the landing data in the landing message.

Abstract: Some embodiments of the present disclosure provide the design and manufacture of an ultra-small chip assembly. The ultra-small chip assembly comprises a die, a plate-like back electrode disposed on the back-side of the die, and one or more plate-like positive electrodes disposed on the front-side of the die. The ultra-small chip assembly is configured such that one end of the plate-like back electrode extends beyond a first side of the die, and each of the one or more plate-like positive electrodes includes an end which extends beyond a second side of the die. By attaching both the plate-like back electrode and the plate-like positive electrodes on the surfaces of the die, and directly using the exposed ends of the plate-like electrodes as the lead-out electrodes for the chip assembly, the electrical connections outside of the die only occupy a very small volume.

Abstract: The present invention relates to a method for detecting landing quality of an aircraft, comprising: determining whether a vertical speed rate is greater than a first preset value or a vertical acceleration is greater than a second value when the aircraft landing; collecting landing data; generating a landing message based on collected landing data in response to that the vertical speed rate is greater than the first preset value or the vertical acceleration is greater than the second value when the aircraft landing; storing or transmitting the landing message; and determining the landing quality of the aircraft based on the landing data in the landing message.

Abstract: A connecting mechanism for a battery case and a main body of a portable electronic device includes a main body (10), a connecting member (20), a cover (30), and a shaft (40). The main body has a receptacle (162), and a recessed portion (192) for receiving the battery case. The connecting member has a body (22) and one or more mounting portions (24). The cover defines a sliding space. The shaft extends through the mounting portions and is received in the receptacle. Thus the connecting member is rotatable relative to the main body about the shaft. The connecting member is received in the sliding space and can slide along the sliding space relative to the cover. Thus the cover is both rotatable and slidable relative to the main body, and need not be detached from the main body.

Abstract: A hinge assembly includes a body drive member (1), a cover drive member (2), and a locating member (3). The body drive member has an outer screw thread (16) on an outer periphery thereof. The cover drive member has a central cavity (212, 224), and a projection (223) and an inner screw thread (216) formed in the cavity. The locating member has a projection (31) formed on an outer periphery thereof, and a central hole (33). The body drive member extends through the cavity and the hole, thereby integrating the hinge assembly into a complete unit, with the thread of the body drive member engaging with the thread of the cover drive member, and the projection of the cover drive member movably engaging with the projection of the locating member. The hinge assembly exerts reduced force on a foldable electronic device when the foldable electronic device is opened or closed.

Abstract: A portable electronic device includes a removable panel (10) defining a first latching hole (122) therein, a knob (30), and a base cover (40). The knob includes an operating portion (31) and a shaft portion (32). A catch (321) extends from the shaft portion. The shaft portion is rotatably received in the first latching hole, with the operation portion being above an upper surface of the removable panel, and the catch being below a lower surface of the removable panel. A second latching hole (450) and a latching hatch (454) are defined in the base cover. The removable panel is attached to the base cover by way of the shaft portion of the knob being inserted into the second latching hole with the catch being received through the latching hatch, and the operating portion of the knob then being rotated so that the catch is engaged below the base cover.
