Abstract: A tubular article formed of multilayer differentially cross-linked heat sealable film suitable for the manufacture of bags used in the packaging of meats. The multilayer film contains at least two layers the inner of which is a heat sealable layer containing an antioxidant cross-linking inhibitor in an amount sufficient to inhibit the cross-linking of that layer by irradiation. Accordingly, upon exposure of the multilayer film to radiation, the outer layer will be cross-linked to a greater extent than the first heat sealable layer.

Abstract: In an electrically driven hammer, in particular a percussion riveter, the assembly expenditure, in particular of the electrical components, is to be reduced. For this purpose, the on/off switch (17) traditionally located in the handle (7) is moved to the housing (2) located opposite to the handle and is operated by thumb and forefinger. This has the advantage that no electrical components are accommodated inside the handle (7) any more. The switch (17) is connected to a locking handle (16) which is displaceable transversely to the axis (6) of the tool receptacle (5) for switching on and off. All electrical and electronic components such as motor (3), switch (17), electronics (31) and mains connection cable (32) are integrated in a motor module (36). As a result, the electrical components are also better protected in the case of an impact of the hammer. <IMAGE>

Abstract: A cache organizational signal ("CORG signal") selects between cache organizations. A cache organization is chosen according to the speed of the main memory that is paired with the cache to handle different size blocks of instructions. When the CORG signal organizes the cache to handle blocks having few instructions per block, many blocks are present and a higher hit rate occurs, which works well with a fast main memory. When the CORG signal organizes the cache to handle blocks having more instructions per block, fewer blocks are present, a lower hit rate occurs, and processor idle cycles decrease, which works well with a slower main memory.

Abstract: A pair of stretching pulleys (3a,3a) are rotatably mounted on a pair of support plates (3,3) within a housing (1). A belt (3b) is wound around the upper part of the stretching pulley and a number of turn pulleys. A film (F) introduced onto the stretching pulley is held between the belt and the stretching pulley and is transferred. Air flow generated by a fan (51) and heated with a heater (5) is blown against the film through a louver and circulates through bellows mounted to the housing to return to the fan. The stretching pulley is partially cooled in a water bath (4c). The support plates are rotatably connected to screw shafts, thereby changing a distance and angle between the plates. The stretch width or stretch ratio of the film is thus adjusted with the change of the distance and angle.

Abstract: A macrocell with product term allocation and adjacent product term stealing is disclosed. Programmable configuration switches provide product term allocation by directing input product terms to an OR gate or to the secondary inputs to a register. Adjacent product term stealing is accomplished by providing the output of the OR gate of each macrocell as an input to the OR gate of an adjacent macrocell. By using the output of the OR gate of the first macrocell, the adjacent macrocell steals the product terms and the OR gate of the first macrocell for use in its own OR gate. An arbitrarily wide OR function can be implemented by daisy chaining the OR gates of adjacent macrocells. Because programmable configuration switches can direct individual input product terms to the register logic instead of the OR gate, the register logic can be used even when an adjacent macrocell steals the OR gate.

Abstract: A data file having a plurality of data blocks is divided into one or more transfer units of data blocks. Before data storage, each transfer unit of data blocks is subjected to its own data compression cycle to create a group of compressed data blocks. The size of the data transfer unit, in bytes, is selected to be facile for addressing and retrieving individual recorded groups of compressed data blocks while providing good channel utilization and compression efficiency. Also the data-transfer unit size is selected in part based upon data storage efficiency, i.e. the storage of the compressed data should fill as many addressable data storage areas as possible. Upon recording each group of compressed data bytes, an entry is made into a file directory for enabling addressing the recorded compressed data blocks.

Abstract: 57 A liquid crystal display element includes a transparent substrate (11), a plurality of source and gate buses (18,19) formed on the substrate (11), thin film transistors (16), each connected to a source and gate bus (18,19) and pixel electrodes (15), each connected to a drain electrode (15a) of the thin film transistor (16). 
     One end portion of each pixel electrode (15) is extended under a gate insulating film (22) underlying the neighbouring gate bus (18) and defines an additional capacitance region (30). The extended portion of the pixel electrode (15) is divided into a plurality of comb-tooth-like electrodes (15b), each defining divided additional capacitors. One of the comb-tooth-like electrodes (15b1) is separated by a gap (40) from the pixel electrode (15), and first and second electrodes (41,42) for laser welding use are formed on the comb-tooth-like electrode (15b1) and the pixel electrode (15) facing each other across the gap (40). The first and second electrodes (41,42) form series-connected first and second capacitances (C1 b,C1 c) for laser welding use between them and a third electrode (43) for laser welding use formed above them with a gate insulating film (22) interposed therebetween. When one of the divided additional capacitors connected to the pixel electrode (15) is bad in insulation, the defective one of the divided additional capacitors is cut off and the first and second capacitances (C1b,C1c) are caused to short by welding, whereby the total additional capacitance can be held substantially constant.

Abstract: A battery pack for a computer system including static memory to maintain battery operating parameters and charge information, a real time clock (RTC) for measuring periods of non-use of the battery and a communication means to exchange the battery information with a microcontroller located in the computer system. The static memory, RTC and communication means is preferably in the form of a single RAM/RTC chip. The battery pack also includes circuitry to maintain power to the RAM/RTC from the battery if AC power is not available. The microcontroller detects the presence of the battery and retrieves the present time from the RTC, a timestamp indicating time or removal of the battery and other operating parameters and charge information from the battery pack, and controls the charging functions of the battery accordingly. The microcontroller also updates the charge information of the battery pack while performing other housekeeping functions of a DC-DC converter. The microcontroller further controls a switch located in the charge path of the battery to control fast charging. Trickle charge is simulated by pulsing the switch at a predetermined duty cycle and period. The microcontroller may be placed in standby to conserve energy, while also monitoring the standby switch to pull the computer system out of standby mode if the standby switch is pressed. This allows the keyboard controller 21 to be shut off during standby mode to conserve energy.
