Abstract: A protective sleeve having an external sound-amplifying member is configured to cover a portable electronic product having an audio port, and it includes a covering element covering the portable electronic product and a sound-amplifying member. A surface of the covering element is provided with a connecting hole in communication with the audio port. The sound-amplifying member is hollow and connected to the outside of the covering element. One end of the sound-amplifying member is formed into an insertion section inserted into the connecting hole, and the other end thereof is formed into a sound-amplifying section. The sound of the portable electronic product is emitted from the audio port and amplified through the sound-amplifying member and the sound-amplifying section. By this structure, an external loud speaker is unnecessary, and the protective sleeve itself can generate a sufficient sound-amplifying effect, thereby increasing the functionality and practicability of the protective sleeve.

Abstract: A protective sleeve having a built-in sound-amplifying channel is configured to cover a portable electronic product having an audio port. The protective sleeve includes an accommodating portion and a sound-amplifying channel. The accommodating portion is provided in the protective sleeve for allowing the portable electronic product to be accommodated therein. The sound-amplifying channel is formed in the protective sleeve. One end of the sound-amplifying channel is connected to the audio port, and the other end thereof protrudes from the protective sleeve to form a sound-amplifying section. The sound of the portable electronic product is emitted from the audio port and amplified through the sound-amplifying channel and the sound-amplifying section. Thus, an external loud speaker is unnecessary, and the protective sleeve itself can generate a good sound-amplifying effect, thereby increasing the functionality and practicability thereof greatly.

Abstract: A one-piece support stand is provided for slantingly supporting an object on a work surface, and the support stand includes a central folding line for dividing the support stand into a left support panel and a right support panel interconnected with each other, and each of the support panels being substantially in a triangular shape and having a bottom edge and a bevel edge, and an inverted hook portion being formed at an intersection of the bottom edge and the bevel edge and bent towards the bevel edge, wherein the support stand is erected on the work surface by means of setting an included angle between the two bottom edges, and the two bevel edges and the two inverted hook portions being provided for supporting the object. The support stand features of a firm support, a foldable design, a convenient carry, a simple manufacturing procedure and a low manufacturing cost.

Abstract: A supporting stand with an angle adjustment function includes two plates and an angle-adjusting means. The angle-adjusting means includes a locking ring, two protruding rings and an adjusting rod. The locking ring is provided on one plate and has axial grooves. The two protruding rings are provided on the other plate. The locking ring is coaxially disposed between the two protruding rings. One of the protruding rings is provided with a restricting slot aligned with the axial grooves. The adjusting rod penetrates the two protruding rings and the locking ring. The adjusting rod is formed with an engaging key engaged with one axial groove and the restricting slot. When the engaging key is removed from the axial groove, the two plates rotate relative to each other by using the adjusting rod as the center of rotation, thereby adjusting the inclination angle of the supported object.

Abstract: The present invention discloses a soluble polythiophene derivative containing highly coplanar repeating units. The coplanar characteristic of the TPT (thiophene-phenylene -thiophene) units improves the degree of intramolecular conjugation and intermolecular ?-? interaction. The polythiophene derivative exhibits good carrier mobility and is suitable for use in optoelectronic devices such as organic thin film transistors (OTFTs), organic light-emitting diodes (OLEDs), and organic solar cells (OSCs).

The first electrical contacts are disposed on a first side of the FPC board, and the second electrical contacts are disposed on a second side of the FPC board. The IC chip is disposed on the FPC board and bonded to the leads of the FPC board to thereby form electrical connection. The total thickness of the FPC board and the chip is not larger than 0.5 mm.

Abstract: A protection cover is used for sleeving over a portable product so as to help protect the product from being scratched. The protection cover includes a shock-absorbing structure for shielding and concealing a corner of the portable product. The shock-absorbing structure is formed with an air chamber bulging outwardly from the corner of the portable product. The shock-absorbing structure further has an inner region that defines an opening for access into the air chamber and that abuts tightly and sealingly against the corner of the portable product so as to convert the air chamber into an air-trapped chamber when the protection cover is sleeved over the portable product.

Abstract: A protective jacket for covering an electrical device is provided. The protective jacket includes a first shell and a second shell. The first shell includes a front cover, a rear cover, and an elastic strip. The front and the rear covers are formed apart from each other and have an individual hollow for receiving the insertion of the device. The elastic strip is formed between these covers. A space is defined on the first shell by theses covers, and the elastic strip together. The second shell is configured to be disposed within the space of the first shell, and has a slot for receiving the insertion of the device. Therefore, the protective jacket conforms to the shape of the device and is capable of covering the device compactly for preventing damages due to collision and avoiding dust and mist pollution so as to increase the life of the device substantially.

Abstract: A memory structure and data writing method thereof includes a power supply circuit and a bridge circuit. The bridge circuit is driven by the power supply circuit, and operate in a plurality of conduction modes. The memory structure only requires one set of power supply circuit and does not need to know the resistance of the bit line in advance, also the signal error is hardly occurred when the memory structure is switching between positive and negative.

Abstract: A ridge-embedded softball or a ridge-embedded baseball in the present invention consists a spherical core, two cover pieces enclosing the core, and two threads to stitch the two pieces together. The feature of ridge-embedded softball or baseball in the present invention is that each cover piece has a stuffing strip embedded near the peripheral distal edge to create the ridges of the softball or baseball. Because the stuffing strips are firmly clamped between an outer skin and an inner fabric layer of the two cover pieces and can not squirm, the ridges are particularly and precisely defined on the softball or baseball to make the softball or baseball easily controlled during play.
