Abstract:
A boot for an optical fiber adapter according to the present disclosure is provided. The boot includes an elastic hollow cylinder and a shape-maintainable member. The hollow cylinder defines an axial direction and the shape-maintainable member is formed on inner surfaces of the hollow cylinder. According to the present disclosure, the boot may be bent to a desired shape in subjection to an external mechanical force. When the boot is bent, the shape-maintainable member will also be bent accordingly. The boot may still be kept in the desired shape even though when the external mechanical force is removed. The boot may be bent to an original shape with an appropriate mechanical force.
Abstract:
A rivet gun has a barrel, a handle assembly, a cylinder and a seal ring assembly. The handle assembly is mounted under the barrel and has a hydraulic shaft and a handle mounted around the hydraulic shaft and having an annular shoulder. The cylinder has a top cover, an annular body and a bottom seat. The top cover is mounted under the handle and contacts the annular shoulder. A diameter of the top cover is larger than a diameter of the annular shoulder such that an outer periphery of the top cover protrudes radially out from an outer periphery of the annular shoulder instead of being covered by the annular shoulder. The annular body is mounted detachably on the top cover. The bottom seat is mounted detachably on the annular body. The rivet gun is allowed to change cylinders of different sizes or types.
Abstract:
A rivet gun has a barrel, a shaft, a handle and a pneumatic cylinder assembly. The shaft is mounted under the barrel. The handle is mounted around the shaft. The pneumatic cylinder assembly is mounted under the handle and has a top cover, a fastener, an annular cylinder and a bottom base. The top cover, fastener, annular cylinder and bottom base are detachably assembled so can be replaced easily without changing the whole pneumatic cylinder assembly. The maintenance costs of the rivet gun are reduced.
Abstract:
A multimedia data sharing system and method for a MOST network is disclosed. The system provides a service management module, a data link control module, and a protocol conversion module. The service management module provides state analysis and management for all services of the multimedia data sharing system and records analyzed service states and configuration results in a service management list. The data link control module performs a control and management process for system data streams based on information stored in the service management list. The protocol conversion module retrieves data from a channel register, based on the information stored in the service management list, to perform a MOST link management operation and implements a packaged or an unpackaged operation to data packets for access of the MOST network.
Abstract:
A trigger device is mounted on a rivet gun. The rivet gun has a barrel, a handle and a pneumatic cylinder. The trigger device has an inlet channel defined in the handle, an outlet hole defined through the handle and communicating with the barrel, a valve-driving channel defined in the handle and communicating with the pneumatic cylinder, a space defined in the handle and communicating with the inlet channel, outlet channel and valve-driving channel. A trigger member is mounted on the handle. A two-step pressing assembly is mounted in the space and may be activated to control the rivet gun to eject a core pin of a used rivet or rivet pieces with an unused rivet. High-pressure air from an air source connected to the rivet gun is output only during the ejection operation of the rivet gun to prevent unnecessary air consumption and noise.
Abstract:
A multi-frequency antenna with dual loops is provided. The antenna includes a T-shaped radiator having a first arm and a second arm of unequal lengths as a main body, and two grounded L-shaped radiators, so as to form dual loops. Thus, the antenna can operate in a high-frequency operation mode and a low-frequency operation mode. With the dual loops, the antenna obtains enough bandwidths at high frequency, and also meets the requirements of low frequency. More specific, the antenna meets the requirements of high-frequency systems, such as DCS/PCS/UMTS and those of low-frequency systems, such as AMPS/GSM.
Abstract:
A center position device of a piston rod of a riveter primarily comprises a position device screwed on a threaded hole below a handle, wherein the position device comprises a pillar hole for being penetrated by a piston rod and a sealing ring fitted closely with the piston rod. A position ring, a ring trench, and a sealing ring are mounted to align the same centerline. At least two ring surfaces forms on an opening of the threaded hole of the handle to which the position device is screwed. When the position device is screwed to the threaded hole, the position ring of the position device touches closely with a ring surface. When the position device is screwed and fixed to the threaded hole of the handle, the centerline of the position will not suffer from deviation to prevent the accuracy of displacement of the piston rod from being affected.
Abstract:
A torque tool is provided, including: a barrel; a first member disposed to the barrel, including at least one first engaging portion; a second member disposed in the barrel, including at least one second engaging portion, the at least one second engaging portion and the at least one first engaging portion being disengageably engaged with each other; an elastic mechanism, disposed inside the barrel and including elastic arms, the second member being configured to abut and radially deform the elastic arms; wherein when there is a torsional three greater than a preset torque value between the at least one second engaging portion and the at least one first engaging portion, the second member urges and radially defines the plurality of elastic arms so that the at least one second engaging portion and the at least one first engaging portion are relatively slipable and disengageable.
