Abstract: A semiconductor buffer circuit and buffering method for driving capacitive loads that enhances the current sinking and sourcing drive characteristics at times when the input signal is changing. Two transistors (12,14) are used, a source follower transistor (12) and a current source pull-down transistor (14), with an input signal (V in ) applied to the con­trol input of the source follower transistor (12). The complement (V in ) of the input signal (V in ) is capacitively coupled to the control input of the current source pull-down transistor (14). As a result, changes in the input voltage increase or decrease the conductivity of the current source pull-down transistor (14), thereby allowing the capacitive load (13) to be charged and discharged more efficiently.

Abstract: Disclosed is a method of making a polymer contain­ing more than 50 to about 95 mole percent, preferably 65 to 80 mole percent, of units derived from maleic anhydride and the balance units derived from at least one 1-alkene. Spe­cifically, the present invention provides for a method for making a free radical addition polymer of maleic anhydride and at least one 1-alkene characterized by the steps of
     (A) mixing maleic anhydride with at least one 1-alkene selected from the group consisting of 1-alkenes having from 4 to 30+ carbon atoms in the presence of an effective amont of a thermally decomposable initiator to initiate the polymerization reaction at a temperature of from about 145°C to 200°C, preferably from about 160°C to 200°C, to form a reaction mixture wherein a major portion of the maleic anhydride and 1-alkene is proportionally added over a period of time at a rate which is substantially equal to the rate of reaction of the maleic anhydride and 1-alkene to form said reac­tion mixture and the molar ratio of maleic anhy­dride to total 1-alkene present is maintained at a ratio of more than 50:50 up to about 95:5 during the course of the reaction; and   (B) thereafter maintaining the reaction mixture at a temperature of from about 145°C to 200°C, prefer­ably from about 160°C to 200°C, until a polymer containing more than 50 mole percent up to about 95 mole percent of maleic anhydride is obtained.   
     In an alternative embodiment, the method further comprises preparing a precharge of maleic anhydride and the 1-alkene selected in more than a 50:50 to about 95:5 molar ration, heating the precharge to 145°C to 200°C and there­after mixing the remaining reactants into the precharge.

Abstract: An improved transmitter having protection from undesired out-of-band radiation caused by high frequency components in a supplied signal to be transmitted uses means for determining when the supplied signal is such as to cause out-of-band radiation. A resulting control signal then reduces the amplitude of the higher frequency components of the supplied signal relative to the remainder of the signal, thereby preventing out-of-band radiation.

Abstract: The invention relates to a method of correcting errors in encoded uncorrected data in a disk storage device, employing a multiple level error correction code for use with records of varying length, including initially formatting the data into blocks, each comprising subblocks, which, except for possibly the last, are of equal size, the number of subblocks in any record being determined by the length of that record. 
     The method is characterised by the steps of statistically determining, as a function of subblock size, first level correction capability and the length of the longest record anticipated, a number representing the minimum number of subblocks which may be in error and correctable; transmitting the uncorrected data to a storage director; performing at least a portion of the first level of error correction at the storage device; and, after all uncorrected data has been received by the storage director, transmitting error information reflecting first level error pattern and location to the storage director for completion of the first level of correction and performance of subsequent levels of correction. 
     The invention also relates to apparatus for performing a method of correcting errors as above.

Abstract: An electronic weighing instrument includes an IC card reading and writing device. An IC card is inserted into the IC card reading and writing device, and as a commodity to be weighed is designated by inputting, a price per unit weight of the designated commodity preset in the IC card is read out. A price of the commodity is calculated from the price per unit weight and a weight of the commodity obtained from a digital signal developed from a load detector, and the weight and the price are indicated on a display unit while a code, the weight, the price per unit weight and the price of the commodity are registered into a registration memory of the IC card. Where a plurality of such weighing instruments are installed, there is no need of provision of a cable interconnecting the weighing instruments. Further, since prices per unit weight of commodities are stored in the IC card, the capacity of the memory required for each weighing instrument can be minimized.
