Abstract: Vias, along with methods for fabricating vias, are disclosed that exhibit reduced capacitance and resistance. An exemplary interconnect structure includes a first source/drain contact and a second source/drain contact disposed in a dielectric layer. The first source/drain contact physically contacts a first source/drain feature and the second source/drain contact physically contacts a second source/drain feature. A first via having a first via layer configuration, a second via having a second via layer configuration, and a third via having a third via layer configuration are disposed in the dielectric layer. The first via and the second via extend into and physically contact the first source/drain contact and the second source/drain contact, respectively. A first thickness of the first via and a second thickness of the second via are the same. The third via physically contacts a gate structure, which is disposed between the first source/drain contact and the second source/drain contact.

Abstract: A charging device and a safety function control circuit and method thereof are provided. When a charging device is not connected to a load, a converted voltage value of a power connection terminal of the charging device is kept to be lower than a safe voltage value so as to maintain a safe mode. The safety function control circuit includes a first control module and a second control module for constant voltage control. The first control module and the second control module perform matching control on a power conversion circuit of the charging device, and in case of a single fault of one of the control modules, the other module is still capable of keeping the converted voltage value to be less than the safe voltage value. Thus, it is ensured that the safe mode stays functional in case of a concurrency of both a single hardware fault and a single firmware fault.

The two wire collecting bases are disposed on the two side walls respectively or on one of the two side walls. Each wire collecting base has at least one wire collecting part. The extension wire collecting base has at least one extension wire collecting part. The extension wire collecting base can couple with the wire collecting base.

Abstract: A multi-output buck converting apparatus with a controllable energy-releasing function includes a main buck converter and at least one auxiliary buck converter to provide multi-output voltages. The multi-output buck converting apparatus further includes an energy releasing unit and an abnormal voltage signal generating unit. The abnormal voltage signal generating unit generates a control signal to control a switch device of the energy releasing unit when the multi-output buck converting apparatus shuts down. Therefore, the energy, which is stored in the auxiliary buck converter, can be released through the energy releasing unit so as to avoid returning the energy to the main buck converter and rebounding a main output voltage.

Abstract: A multi-output buck converting apparatus with a shutdown protection includes a main buck converter and at least one auxiliary buck converter to provide multi-output voltages. The multi-output buck converting apparatus further includes an abnormal voltage signal generating unit. The abnormal voltage signal generating unit generates a control signal to control switch devices of the auxiliary buck converter when the multi-output buck converting apparatus shuts down. Therefore, the stored energy in the auxiliary buck converter can be released through internal loops or external loops with connected operational loads so as to avoid the recovering energy rebounding a main output voltage of the main buck converter.

Abstract: A switch device includes two contactors. Each contactor respectively includes at least two conductors, a magnet, and a coil spring. The conductors are connected to a power source via a powered electronic circuit. The circuit is designed to be in a normally open or closed initial condition. The magnet is directly or indirectly connected to the conductors. The coil spring is directly or indirectly located between the conductors and the magnet. The conductors change their normally open or closed condition into a temporarily closed or open condition to turn on or off the switch device when the contacts move near enough to permit magnets to interact magnetically. The coil spring forces the conductors to recover their original normally open or closed condition when the magnets cease to interact magnetically.

Abstract: An aquatic ornamental landscape device includes a main portion provided in a water tank and made of a soft material with its specific weight not larger than that of the water so as to float in the water tank, and connected with a down leading member to stay at a certain location without hampering the main portion from swinging or wriggling, a magnetic member provided in the main portion, and a magnetic inducing base provided at the outer side of the water tank and containing a hollow housing to accommodate a motor and a gear set driven by the motor while an axial of the gear set is connected also to a magnetic member which is driven and rotates to generate changed magnetic field against the water tank for the main portion to stay in its place and naturally swing or wriggle when subject to the alternative magnetic force of attraction and repulsion between the magnetic members in the main portion and the magnetic inductive base.
