Abstract: Disclosed is a trench gate IGBT. A dummy gate is arranged between two real gates. An emitter metal is in contact with the dummy gate, so that an emitter metal contact area is not limited to an area between trenches. The emitter metal contact area includes an area where the emitter metal is in contact with the dummy gate, thereby enlarging the emitter metal contact area, and accordingly reducing a distance between each of the real gates and the dummy gate. Consequently, the distance between each of the real gates and the dummy gate is no longer affected by a minimum emitter contact area, and a turn-on voltage drop of the trench gate IGBT can be greatly reduced.

Abstract: A method and apparatus for generating a preamble for use in DVB-C2 cable transmission standard is provided. The preamble has multiple functions including frame timing, synchronization, frequency offset estimation, system information signaling and initial channel estimation. In accordance with an implementation, a complementary sequence is inserted as a header and the complementary sequence and system signaling bits are mapped into modulation symbols for transmission on allocated even channels only of the cable transmission system.

Abstract: A vacuum type positioning apparatus (10), used in insert-molding machine for positioning an inserted workpiece (181), is provided. The vacuum type positioning apparatus includes a vacsorb unit (11) and a positioning unit (15). The positioning unit connects with the vacsorb unit. The positioning unit has an attaching wall (1912). The vacsorb unit provides a suction pressure for the positioning unit to attach the inserted workpiece with the attaching wall.

Abstract: A card connector adapted for receiving a card comprises an insulating housing (1) defining a card receiving space with a card insertion/ejecting direction; a plurality of contacts (2) retained in the insulating housing and an ejector (3) received in the insulating housing for ejecting the card. The ejector comprises a slider (30) movable along the card insertion/ejecting direction, a resilient member (31), a pin member (32) and a latching member (33) retained to the slider and having a locking portion (330), during an insertion process of the card, the latching member moves upwardly together with the slider, and brings the locking portion to move upwardly and lock the card.

Abstract: This invention relates to a method for the separation of oil, protein, carbohydrates, shell, and minor toxic components from seeds. The oil seed is subjected to a dehulling process to separate out the hull and kernel and the dehulled oil seed is then compressed into flakes under low temperature. The oil seed is then dephenolized and undergo low temperature delintion. In addition, direct hydrolyzation of the oil-complex is carried out. This technology can be used to produce high quality oil and obtain hydrolyzed protein, thereby comprehensively utilizing the oil seed.
