Abstract: The present disclosure provides a semiconductor package. The semiconductor package includes a first substrate, a first die, a plurality of first electrical contacts, a first encapsulant, a second substrate, a second die, a third die, a plurality of second electrical contacts, a second encapsulant and an adhesive layer. The first die is disposed on a first surface of the first substrate. The first electrical contacts are disposed on a second surface of the first substrate and are electrically connected to the first die. The first encapsulant is formed on the first surface of the first substrate to enclose the first die. The second and third dies are disposed on a first surface of the second substrate. The second electrical contacts are disposed on a second surface of the second substrate and are electrically connected to the second and third dies. The second encapsulant is formed on the first surface of the second substrate to enclose the second and third dies.

Abstract: When opening a document, the character codes of all characters in the document are uploaded to a font server, then all possible glyphs corresponding to the uploaded character codes of characters tagged with a font are selected from a font file which stores a plurality of glyphs of the font to form a glyph subset. And the glyph subset is then downloaded.

Abstract: A transmission shaft is disposed between a driving device and at least one driven device. At least one centrifugal device is disposed on the transmission shaft. The centrifugal device generates a centrifugal force and applies an inertia affect formed by the centrifugal force to the transmission shaft, so as to drive the transmission shaft to rotate. Energy generated by the driven device is greater than energy consumed when the driving device drives the driven device, thereby effectively reducing the consumption of earth resources and effectively solving a problem of earth environmental protection.

Abstract: A closed energy combined cycle system and an operation method. This includes a power supply mechanism, for providing a high voltage; a driving device, controlled by the high voltage of the power supply mechanism; and a power generation device, in which the driving device rotates the power generation device to generate power through a transmission shaft, and the power generated by the power generation device supplied to the power supply mechanism and a load, in which the driving device rotates the transmission shaft at a high rotational speed, the transmission shaft rotates the power generation device to generate the power. Power generation efficiency of the power generation device may be enhanced, thereby greatly improving overall efficiency of the system, and resources used by the driving device for rotating the power generation device may be reduced, thereby effectively reducing consumption of earth resources and providing earth environmental protection.
