Abstract: An integrated circuit package including electrically floating metal lines and a method of forming are provided. The integrated circuit package may include integrated circuit dies, an encapsulant around the integrated circuit dies, a redistribution structure on the encapsulant, a first electrically floating metal line disposed on the redistribution structure, a first electrical component connected to the redistribution structure, and an underfill between the first electrical component and the redistribution structure. A first opening in the underfill may expose a top surface of the first electrically floating metal line.

Abstract: A method for controlling a fan in a fan start-up stage including a first time period and a second time period comprises the following steps of: during the first time period, continuously providing a first driving signal to drive the fan; and during the second time period, continuously providing a second driving signal to drive the fan; wherein, the signal value of the first driving signal gradually decreases until being equal to the signal value of the second driving signal. Wherein the signal value of the first driving signal non-linearly decreases, the signal value of the second driving signal is an unchanged value. Wherein, the first time period and the second time period are adjusted for a different fan but the sum of the first time period and the second time period is always the same. A fan is also disclosed.

Abstract: An apparatus for producing silicon carbide crystal is provided and includes a composite structure formed by a plurality of graphite layers and silicon carbide seed crystals, wherein a density or thickness of each layer of graphite is gradually adjusted to reduce a difference of a thermal expansion coefficient and Young's modulus between the graphite layers and silicon carbide. The composite structure can be stabilized on a top portion or an upper cover of a crucible made of graphite, thereby preventing the silicon carbide crystal from falling off.

Abstract: A spindle braking mechanism of a lathe includes a pressing piece held in a head stock of the lathe, a brake pad positioned around and securely coupled to a spindle projecting from the head stock, a disc-brake disc interposed between the pressing piece and the brake pad, several elastic pushing elements positioned around the spindle and coupled to the head stock for biasing the pressing piece away from the disc, and two sensing and detecting devices coupled to the head stock for detecting motion of the pressing piece; a passage extends through the head stock, and a power source is used to provide pressure to the pressing piece through the passage; the disc will be pressed against the brake pad to stop the spindle when the power source is actuated; the elastic pushing elements will push the pressing piece away from the disc when the power source is turned off.

Abstract: A lathe includes a stock, a shaft, a power source, gripping bars, and a platform; the stock has a shaft seat secured therein, which has a hollow holding portion, and an inner protrusion; the shaft is passed in the shaft seat in a movable manner, and has a head having a step-shaped portion and projecting into the holding space; the power source is used for actuating the shaft; the gripping bars are spaced around the shaft head, and each have inner and outer recesses; the platform has a hollow portion, and an inner protrusion right above and facing the inner protrusion of the shaft seat; when the shaft is moved upwards, the step-shaped portion will be pressed against upper edges of the inner recesses to raise the gripping bars; thus, both the protrusions are tightly held within the outer recesses of the gripping bars, and the working platform secured in position.

Abstract: A digital video camcorder capable of recording and playing golfing actions comprises a lens set, an optical sensor, an image processing module, an image input module, an image display module, a mode select module, a microprocessor, a memory unit and a display unit. After a function of the mode select module is selected, a first image sensed by the optical sensor via the lens set and processed by the image processing module or a second image inputted by the image input module can be recorded into the memory unit. The microprocessor and the image display module can simultaneously display two images already stored in the memory unit on the display unit in a slow-motion, freeze-frame or split-frame way. A touch pen can then be used to directly draw illustration lines on the display unit.
