A caster structure has a screw hole formed at the middle of a carrying plate and provided for passing, screwing, and pressing a screw, and then screwing and pressing tightly with a nut, so that the installed screw has a smaller thickness to lower the center of gravity of an installed wheel in addition to giving a dual nut fixing effect. The caster has bearings which are mainly thrust bearings for bearing a relatively larger axial gravity to prevent the bearing from being damaged by gravity and the balls from falling out. The bearings are limited and positioned securely to prevent installation gaps and dusts, to maintain a flexible rotation of the caster.

A power supply system is provided to control one or more power supply units associated with an information handling system. A first power supply unit and a second power supply unit are electrically coupled to the information handling system. A controller is provided in communication with both the first and second power supply units. The controller functions to select one of the first and second power supply units to electrically power the information handling system. The non-selected unit generates zero output.

A circuit board assembly is provided. The circuit board assembly includes: a first circuit board; a second circuit board; a bracket for supporting the second circuit board; and an interconnect apparatus for a connection and a disconnection of the first circuit board and the second circuit board, wherein the interconnect apparatus includes a first connector disposed on the first circuit board and a second connector disposed on the second circuit board (one is a male connector and the other is a female connector). The circuit board assembly includes a lifting and lowering apparatus for vertically lifting or lowering the bracket so that after the connection the second connector is vertically disconnected from the first connector and after the disconnection the second connector is vertically connected to the first connector. An electronic device having the circuit board assembly is further provided.

A calculator comprises an input having an UNDO key for recovering cleared values. When displayed data or recorded data of memory is cleared by pressing one of deletion keys, the cleared data is pushed into a stack register. A flag register is set when the displayed data or recorded data is cleared by a deletion key. When the UNDO key is pressed and the flag register indicates that the displayed data or recorded data was cleared by the deletion key, a data entry is popped from the stack register, so as to recover the cleared value.

An electronic device capable of counting down to an integral time point has an integral time point selector for setting an integral time point. A timer serves for recording the current time. A synchronous calculating unit serves for reading the integral time point from the integral time point selector and reading the current time from the timer. The time interval from the current time to the integral time point is calculated as a counting down time period. A counter serves for reading the counting down time interval from the synchronous calculating unit and starting to count down.

A data editable statistic calculator having an input device, a memory, a statistic computing unit, and an output device. The input device includes a set of number entry keys for data entry, enabling inputted data to be stored in registers in the memory, so that the user can fetch a specific datum from the registers sequentially with a function key for further editing through the number entry keys. When entering EDIT mode under statistic mode, the user can clearly find out the desired data for editing, and then delete or edit the data. By means of this humanized design, the user can conveniently review the correctness of every inputted data.

An access device of a memory card comprises a substrate for providing a receiving space. The substrate is positioned in an expanding slot of a system mainframe. The receiving space of the substrate has a control panel. The control panel has a control IC for accessing and converting signal formats of a memory card. At an end for outputting data signal on the control panel has a data wire for outputting signals from the control panel. The data wire is directly connected to a specific interface in a mother board of a system. Another data wire connected in parallel with the data wire is connected to an external interface of a back plate of the mainframe so that the external interface is still utilized by other devices. Thereby, the data inputted to the memory card can be accessed directly from the system mainframe without any external device.

The invention concerns a form of lighting decoration hanger structure. It refers especially to a bow form such as those supporting structures used in fishing rod as an arm of uphold. It includes the light hood, the supporting arm, spring lever and its foundation. The axis of the light hood is fixed on the upper end of the supporting arm. The foundation has a protruding fixed base. The lower end of the supporting arm is connected to the fixed base. The main point is that the spring lever located between the light hood and the fixed base. The spring lever has, on its upper and lower end, a ring-like circle and a transition spring. There is also a base lock situated at the fixed base of the foundation. This base lock has a fixed lock on it. The ring-like circle on the upper end of the spring lever is capped on the connector piece between the connector of the light hood and the supporting arm or it could be connected to the upper end of the supporting arm. The transition spring at the lower end of the spring lever is capped on the base lock of the fixed base and is combined with a fixed slot at the foundation so that the spring lever forms a bow-like supporting structure. The aforementioned structure, during movements of the supporting arm, could be pulled to a fix by use of the spring lever; this forms bow-like structure of support as that of the fishing rod. This structure is sufficient in supporting the light hood in limited area in any position pleased. In addition, when the supporting arm moves, the spring lever will display different forms due to principals of dynamics. All these contribute to the variety of external forms which the whole set of light displays.
