Abstract: A packaging method for assembling a captive screw to a printed circuit board (PCB) includes the steps of providing a captive screw having a screw head, a threaded shank and a sleeve; pressing a fixture toward the screw head for a part of the threaded shank to exposed from a distal end of the sleeve, and then clamping the fixture on the sleeve; providing a PCB having through holes and a layer of solder provided thereon; using a tool to pick up the fixture and the captive screw and align the threaded shank with one through hole on the PCB; releasing the fixture and the captive screw from the tool for a flange at the distal end of the sleeve to extend into the through hole; heating, melting and then cooling to harden the solder layer, so that the sleeve is fixedly held to the PCB; and removing the fixture.

Abstract: A mixing pipe for a gas heater includes an intake port through which gas and air are flowed in; a discharge port through which the gas and the air flowed in through the intake port are mixed and discharged; and an acceleration part disposed between the intake port and the discharge port and having a diameter smaller than the a diameter of the intake port, wherein a distance between the intake port and the acceleration part is greater than 0.5 times of the diameter of the acceleration part and smaller than 1.5 times of the diameter of the acceleration part.

Abstract: A coaxial cable connector comprising a connector body; a post engageable with connector body, wherein the post includes a flange; a nut, axially rotatable with respect to the post and the connector body, the nut having a first end and an opposing second end, wherein the nut includes an internal lip, and wherein a second end portion of the nut corresponds to the portion of the nut extending from the second end of the nut to the side of the lip of the nut facing the first end of the nut at a point nearest the second end of the nut, and a first end portion of the nut corresponds to the portion of the nut extending from the first end of the nut to the same point nearest the second end of the nut of the same side of the lip facing the first end of the nut; and a continuity member disposed within the second end portion of the nut and contacting the post and the nut, so that the continuity member extends electrical grounding continuity through the post and the nut is provided.

Abstract: A charging circuit includes a battery pack having a plurality of serially connected batteries and being connected to a power supply; a changeover switch being serially connected to and between any two adjacent batteries; and a precision voltage detector being parallelly connected to each of the batteries for independently detecting a voltage of the connected battery and sending out a detected result to a charging control circuit for controlling the ON/OFF of the changeover switch corresponding to the battery. When a battery is detected by a corresponding precision voltage detector as having been fully charged, the corresponding charging control circuit sets the changeover switch corresponding to the battery to OFF to stop charging the battery. The remaining batteries that are subsequently fully charged are disconnected from the power source one by one until all the batteries in the battery pack have been fully charged. Thus, all the batteries are balance-charged.

Abstract: A phone plug connector device having a preassembled three conductive phone plug and connector, wherein the phone plug includes a conductive tip and a stem, wherein the connector connects the phone plug to a triaxial cable, wherein the triaxial cable comprises a center conductor surrounded by a first dielectric, the first dielectric being surrounded by a first conductive sheath, and the first conductive sheath surrounded by a protective outer jacket, wherein the connector connects the triaxial cable to the phone plug mechanically and electrically by compression.

Abstract: A protective device is applicable to a casing provided with a first coupling portion and configured for use with an outdoor communication apparatus. The protective device includes a body and a shielding portion. The body is configured to shield the front of the casing and provided with a second coupling portion coupled to the first coupling portion. The shielding portion is laterally provided to the side of the body for shielding the casing sideways. Hence, the shielding portion of the protective device shields the casing from direct irradiation of sunlight, prevents the outdoor communication apparatus from being overheated, and protects the outdoor communication apparatus against rainwater and dirt. A casing configured for use with an outdoor communication apparatus and equipped with the protective device is further provided.

Abstract: A self contained geothermal generator includes a boiler, a turbine compartment, an electricity generator, a condenser and an electric cable. The condenser includes a distributor chamber, a peripheral chamber and plurality of tubes disposed between the chambers. The peripheral chamber of the condenser surrounds and cools turbine, elective generator and selector of the condenser departments. The condenser cools and converts exhausted steam back in liquid state and returns it back into boiler for reheating. In a method of using the geothermal generator, water contained within the boiler is converted to high-pressure, super heated steam due to heat from hot rocks contained within a pre-drilled well below the Earth's surface. The steam is used to produce electric energy which is transported up to the ground surface by the electric cable. A plurality of geothermal generators may be used in a “binary” power plant through system of several heat exchangers.

Abstract: A cable television (CATV) entry adapter interfaces to a CATV network and serves as a hub in a Multimedia over Coax Alliance (MoCA) network. MoCA signals are bypassed around the CATV communication paths within the entry adapter to maintain adequate signal strength and to allow a passive port of the entry adapter to be used as part of the MoCA network. MoCA signals are suppressed from exiting the CATV entry adapter onto the CATV network.
