An open end of a standard pipe fitting is enlarged in diameter to coaxially receive an O-ring and a retainer having a cylindrical surface. A plurality of locking teeth project from the cylindrical surface and are engageable with both the inner surface of the fitting and an outer surface of a pipe end inserted coaxially into the fitting open end. Each of the locking teeth have oppositely disposed edges facing obliquely inwardly and outwardly to engage both the pipe end and the fitting and resisting motion of the pipe end relatively to the fitting. In an alternate embodiment, a first plurality of teeth each have an edge facing obliquely inwardly of the fitting to engage the pipe end and resist motion tending to withdraw the pipe end from the fitting. A second plurality of teeth each have an edge facing obliquely outwardly of the fitting and resist motion tending to withdraw the retainer from the fitting.

A method for land seismic data acquisition is provided, together with a seismic cable and a cable spool vehicle for use in the method. In performing the method, the cable spool vehicle mechanically deploys seismic cable with attached sensors according to a desired geophysical spread and at a rate dependent upon the speed of movement of the vehicle substantially without tension in the cable. The cable spool vehicle also allows mechanical pick-up of the seismic cable together with the sensors after the seismic data acquisition.

An apparatus for a photovoltaic module frame assembly comprising a frame member including a vertical member and horizontal member that cover the outer circumference the photovoltaic module, which transforms solar energy into electric energy, and corner member that performs connections and fixation between the horizontal member and vertical member, which provides a solution to alleviate traditional frame structure issues that relate to the sharpness of the corner so that any accidents that may be caused by the corner can be prevented and enhance safety. Also a groove is included to fix the frame onto the corner member that, which covers the photovoltaic module and does not have any sides, and allows accurate coupling by fitting into the frame member so that various designs and formations can be provided.

A system, apparatus, device, tools and method is provided for the insertion of improved anatomically corrected modular design anterior and posterior dental implants, the apparatus including a root component and a head/abutment component, wherein the root component is inserted into the jawbone using precision surgical guide tools in combination with self-limiting surgical templates and a precision adjustable clamping device.

The embodiments of the invention relate to the technical field of antenna tests and especially relate to a mobile terminal antenna test method and system. The method comprises the steps that: a mobile terminal establishes a communication connection with a test terminal through wireless signals; by means of the communication connection, the test terminal controls an antenna of the mobile terminal to establish a wireless radio frequency connection with a test instrument; and the test terminal controls the test instrument to carry out a downlink test on the antenna and/or controls the mobile terminal through the communication connection to carry out an uplink test on the antenna. By adopting the technical scheme provided by the embodiments of the invention, the problems in an existing antenna test that the instrument cost is high, the test efficiency is low, and the antenna test result is inaccurate are solved.

As shown in FIG. 4, as coupling holding means 20 for holding coupling between a socket S10 and a plug P10, an engaging projection 22 is formed in the plug P10 and an engaging recess 21 is formed in the socket S10 so that the socket S10 is coupled with the plug P10 accurately by an operation to engage the projection 22 with the recess 21 after an overriding operation of the projection 22. Additionally, on the plug P10 is provided a cam portion 31 which inclines in substantially a circumferential direction about a central axis running in the coupling direction and a cam follower portion 32 is formed in the socket S10. In a case where an abnormal rotational force exceeding a normal range of use is applied, an automatic release of coupling is made between the cam portion and the cam follower portion.

A reinforcement bar coupler, in which a female thread having an inclined taper plane is formed on the inner surface of a coupler cap, and a clamping spring is inserted into and fastened to the female thread. When a reinforcement bar is inserted into the clamping spring, the clamping spring is closely abutted to the bottom of the female thread and is increased in diameter so that the reinforcement bar slips. With the reinforcement bar being inserted, when an external force is applied in the direction opposite to the direction in which the reinforcement bar is inserted, the clamping spring moves along the inclined taper plane and is decreased in diameter, thereby holding the reinforcement bar. It is therefore possible to easily connect and couple the reinforcement bar with one touch based on a change in the diameter of the clamping spring using a relatively simple configuration.

A combination frame for fixing a display panel module on a display shell is described. The combination frame is constructed by two crossbeams, two vertical beams, and a plurality of coupling devices. The coupling devices adjust an interior size of the combination frame for coupling to the display panel module exactly. The combination frame utilizes adjusting members to fine-adjust an outline size of the combination frame, and further utilizes a backboard to enhance the strength of the combination frame and fix a control circuit board of the flat panel display.

An optical prism that includes an interlock structure that precisely couples to a complementary structure of a refractive lens. For precision, the interlock structure may be formed at the same time and using the same technique as the optical surface of the prism. The interlock structure provides high accuracy when assembling a folded lens system by precisely aligning the object side optical surface of the lens with the image side optical surface of the prism so that the optical axis is centered in the lens. The prism may have refractive power. A portion of the object side surface may be coated with an opaque material to provide an aperture stop at that surface.

A DC blocking device using impedance matching is disclosed. The disclosed DC blocking device comprises: a first strip line configured to receive a signal and including a first line section and a first joining section joined to a part where a signal is received; and a second strip line separated from the first strip line at a designated distance and including a second line section and a second joining section for joining an output signal, where coupling occurs from the first strip line to the second strip line, the first strip line and the second strip line each have at least one bending section, and the first line section and the second line section have smaller line widths than the first joining section and the second joining section. The disclosed DC blocking device has the advantage of minimizing spatial constraints when it is installed in a mobile communication apparatus, and of achieving proper coupling even if the length of the part of the DC blocking device where coupling occurs is reduced.
