摘要： A tape rewinding mechanism for a magnetic recording/reproducing apparatus is disclosed in which, when ejecting the tape from the deck, the reel with the tape installed thereon is driven by a capstan motor, so that the tape can be recovered with a proper tension maintained between the tape and the drum, thereby preventing damage to the tape. A driving gear is installed on a lever of a transmitting gear which is meshed with the capstan gear, and thus, the take-up reel is driven during loading, while the supply reel is driven during an unloading. During a reproduction, the take-up reel and the supply reel are easily driven by the transmitting gear, thereby simplifying the structure of the deck.

摘要： A reel guide apparatus of a magnetic recording/reproducing apparatus accurately seats the supply reel and take-up reel onto a lower chassis of the apparatus. The reels are installed on a slider which is lowered to the lower chassis. Holes in the slider receive reel guide units for stably guiding the reels in the vertical direction. A position determining unit on the lower chassis accurately determines the seating of the tape cassette on the lower chassis. Sensors on the reel guide units and split disc reflectors on the reels facing the sensors result in the generation of reel pulses, which are used to determine remaining tape length, etc.

摘要： A cassette lid opening and closing system for a magnetic recording and reproducing apparatus capable of opening a cassette lid during the seating of a tape cassette on a deck and closing it after the seating is accomplished, to thereby lower the height of the deck, includes a lid-open member operating link for swinging a lid-open member to open the cassette lid during the seating of a cassette holder on a slider, a lever for closing the open cassette lid by releasing a lid-pressing operation of the lid-open member when the tape cassette is moved to a seated position on a lower chassis, and a lever operator for operating the lever, so that the cassette lid is closed during recording or reproducing operation. Advantageously, a closed cassette lid allows a corresponding reduction in the size of the deck.

摘要： The invention provides a method and apparatus for advanced network intrusion detection. The system uses deep packet inspection that can recognize languages described by context-free grammars. The system combines deep packet inspection with one or more grammar parsers (409A-409M). The invention can detect token streams (408) even when polymorphic. The system looks for tokens at multiple byte alignments and is capable of detecting multiple suspicious token streams (408). The invention is capable of detecting languages expressed in LL(I) or LR(I) grammar. The result is a system that can detect attacking code wherever it is located in the data stream (408).

摘要： In a magnetic tape recording/reproducing apparatus, an idler moves an idler gear selectively between a supply reel and a take up reel to transfer power respectively to the reels. During loading of the tape of a cassette tape, an upper chassis, with the tape cassette and drum, is seated on a lower chassis, with the loading and travelling gearing apparatus. During seating operation, the idler is held in a central position by an idler cam having a cam surface to be out of the way of the components on the upper chassis, thereby eliminating interference with the seating operation. During normal tape running operations, the cam surface controls the movement of the idler.

摘要： A digital integrated circuit may include a digital data processing circuit having multiple signal lines that each go through signal transitions during operation of the digital data processing circuit. A digital counter circuit may count the combined number of signal transitions that take place on at least two of the multiple signal lines during operation of the digital circuit. A digital counter circuit may count the number of times a particular pattern of signal transitions takes place on at least one signal line during operation of the circuit. A computer program may receive information indicative of a composition of a digital integrated circuit, input vectors to the digital integrated circuit, and how much power is being consumed by the digital integrated circuit under each of the input vectors. The program may output information indicative of an amount of power being consumed by each of multiple, different sub-sections of the digital integrated circuit while responding to the input vectors.

摘要： An improved deep packet filter system designed to optimize search of dynamic patterns for a high speed network traffic. The improved deep packet filter system is a hardware-based system with optimized logic area. One optimization technique is the sharing of common sub-logic in the hardware design to reduce the number of gates that are required. Another optimization technique is the use of a built-in memory to store portions of the pattern set, also resulting in a reduction of gates. The reduction of the logic area allows the deep packet filter system to be implemented onto a single field-programmable array chip.

摘要： A door mechanism of a tape recorder includes a door axially-coupled at one side of an eject lever for being opened/closed around a pivot shaft during the pivoting of the eject lever, and a link for guiding the opening/closing operation of the door during the pivot operation of the eject lever, in which the door is positioned higher than a cassette lid so as not to contact the cassette lid during a first loading operation of a tape cassette and is positioned as high as the upper end portion of the eject lever after a second loading operation of the tape cassette is completed, thereby permitting the design of an extremely thin tape recorder.
