A bezel assembly includes a bezel body having an opening formed thereon for receiving at least a part of a connecting piece. At least one opening shield is movably disposed on the bezel body and pressing against the connecting piece via an elastic element such that the connecting piece remains contact with the bezel assembly in the opening. The bezel assembly of the present disclosure can be adapted to connecting pieces of various types and standards, such as connectors or ports, so as to improve universality of the bezel assembly and expand the application range.

Bezel assembly and electrical connection apparatus

A high voltage transformer apparatus, including: a tank; a high voltage transformer, disposed upright on one side within the tank, including a first transformer unit configured to generate a positive voltage and a second transformer unit configured to generate a negative voltage; a positive high voltage terminal and a negative high voltage terminal respectively disposed on the other side within the tank opposite to the first transformer unit and the second transformer unit; a first circuit board disposed between the first transformer unit, the first side wall, and the positive high voltage terminal; and a second circuit board disposed between the second transformer unit, the second side wall, and the negative high voltage terminal; wherein the first and second circuit boards are respectively configured to rectify, filter and sample the positive and negative voltages.

High voltage transformer apparatus

The invention relates to a tenofovir prodrug and pharmaceutical uses thereof. In particular, the invention relates to a compound as shown in general formula (I): and its isomer, pharmaceutically acceptable salt, hydrate or solvate, as well as their uses in preparing drugs for treating viral infectious diseases, especially HIV infection, hepatitis B, or diseases caused by hepatitis B virus, wherein the definition of each substituent in the general formula (I) is as defined in the specification.

Tenofovir prodrug and pharmaceutical uses thereof

A method for controlling converter such as a Flyback converter is disclosed. A load of the Flyback converter varies between zero and a peak value. The method includes: a load detecting step for detecting the load; and an operating mode control step for controlling the Flyback converter to switch between two or more of a continuous conduction mode, a valley conduction mode and a burst mode according to the load. A converter such as a Flyback converter is also provided.

Converter and method for controlling the same

A switching power conversion circuit having a two-stage power circuit topology and capable of performing power factor correction is disclosed. In a case that the electrical energy of the switching power conversion circuit needs not to be provided to the system circuit, for example the load and the electronic device fails to be operated, the switching power conversion circuit will be adaptively disabled. As a consequence, the switching power conversion circuit could achieve a power-saving purpose. Moreover, the switching power conversion circuit could be applied to a power supply. When the electronic device is not in use, the power supply has reduced power consumption, thereby achieving a power-saving purpose.
