Abstract:
A ring binder mechanism for retaining loose-leaf pages securely holds closed ring members together to prevent inadvertent loss of pages retained by the mechanism. The mechanism comprises a housing supporting two hinge plates for pivoting motion to open and close paired ring members mounted on the plates. Free ends of the paired ring members have interlocking configurations that securely join together when the ring members close. The configurations prevent misalignment of the closed ring members in all directions transverse to longitudinal centerlines of the ring members. The mechanism also includes locking elements that interact with the hinge plates to block their pivoting motion when the ring members are closed. This holds the free ends of the closed paired ring members together so that the interlocking configurations of the ring members remain interengaged.
Abstract:
A display method that is used for a security device installed with a camera module and a display module includes A. when the security device captured a preset image by the camera module, the security device displaying an interface for entering a password by the display module, and B. when the password is successfully matched, the security device displaying a predetermined object by the display module. By hiding the interface for entering a password, the invention improves the security capability of the device and meets the requirement of information security at present.
Abstract:
A device for extracting a synchronization signal from a video signal has a first comparator and an adjustment circuit. The first comparator receives the video signal, compares the video signal with a first threshold, and generates the synchronization signal according to the compared result. The adjustment circuit receives the video signal, compares the video signal with a plurality of second thresholds of different values, and changes the first threshold according to the compared results.

Abstract:
A method for bonding conductive materials by using composite adhesive made of carbon nanotubes and epoxy resin. Firstly, this composite adhesive is placed between the joining surfaces of the two conductive plates; thereafter an electric current enters from one conductive plate and passes through this composite adhesive, to the other conductive plate. As the electric current passes through the carbon nanotubes, Joule heating results in the overall temperature of the carbon nanotubes-epoxy composite adhesive increasing, leading to speedily joining and patching of the composite adhesive. This method reduces the electrical resistance of the adhesive material by providing a large area and shortening the path of the electric current, also, improving the homogeneity of the temperature of the adhesive and avoiding the positive feedback effect. The simple equipment of this method is not affected by the environment, and effectively reduces the resources and time needed to harden the epoxy resin.
Abstract:
A ring binder mechanism includes an elongate plate having a longitudinal axis. Hinge plates are supported by the plate for pivoting relative to the elongate plate. Ring members are mounted on the hinge plates and moveable between a closed position and an open position. A control structure is supported by the elongate plate and controllably pivots the hinge plates to move the ring members between the closed and open positions. The control structure has a travel bar connected to the hinge plates for moving the hinge plates between the closed and open positions. A spring biases the travel bar toward the closed position.
Abstract:
A three-phase power supply with a three-phase three-level DC/DC converter includes a full-bridge thyristor converter with three-set four in-series power switch elements, a three-phase isolated transformer, a full-bridge rectifier, a rectifying circuit, and a low-pass filtering circuit. The three-phase power supply is used to deliver power energy from the AC input voltage to the load. The power switch elements, which separated to each other at 120-degree phase differences, are controlled through a phase shift scheme. Therefore, the three-level circuit structure is provided to reduce withstanding voltage of the power switch elements, further the zero-voltage switching (ZVS) is achieved by the isolated transformer and the power switch elements to increase the efficiency of the DC/DC converter.
