    摘要： Proposed is a novel polysiloxane-polyether block copolymer having excellent heat resistance, which is characterized by the molecular structure consisting of repetition of diorganopolysiloxane units and polyoxyalkylene units having a bisphenol linkage of the formula --O--Pn--CMe.sub.2 --Pn--O-- in the unit, Pn being a 1,4-phenylene group and Me is a methyl group. This polysiloxane-polyether block copolymer can be prepared by conducting a hydrosilation reaction between a diorganopolysiloxane terminated at each molecular chain end with a silicon-bonded hydrogen atom and a polyoxyalkylene compound having the bisphenol linkage in the molecule and terminated at each molecular chain end with an alkenyl group or, preferably, allyl group in the presence of a platinum catalyst. The stability of the block copolymer obtained by the hydrosilation reaction can be further improved, when the block copolymer has a silicon-bonded hydrogen atom as the terminal group, by reacting the silicon-bonded hydrogen atom with water or alcohol to be converted into a silanolic hydroxy group or alkoxy group.

    摘要： An image data coding apparatus performs first and second coding processes. A controller outputs first and second control signals. An orthogonal transform circuit performs orthogonal transform on image data of one screen and generates an transformed output. A quantizing circuit quantizes the transformed output with a predetermined temporary first quantization width upon reception of the first control signal and generates a first quantized output, and quantizes the transformed output with an optimal second quantization width upon reception of the second control signal and generates a second quantized output. An entropy coding circuit codes the first quantized output and generates a first coded output, and codes the second quantized output and generates a second coded output. An amount-of-codes calculator calculates the amount of codes of the first coded output for each block and calculates the amount of codes of one screen based on the amount of codes for each block. An assigned-amount-of-codes determining circuit determines the amount of codes assigned to each block based on the amount of codes for each block and the amount of codes of the one screen, and the target amount of codes. A quantization width predicting circuit predicts the second quantization width based on the amount of codes of the one screen. A coding stop circuit supplies a coding stop signal to the entropy coding circuit when the amount of codes of the second coded output exceeds the assigned amount of codes.

    摘要： Recognition character candidates and their similarities for each character obtained by a character recognition section from an input character string are stored in a first recognition result memory, and recognition character candidates obtained by rotating the corresponding characters through 180 degrees and their similarities are stored in a second recognition result memory. Address pointers for accessing the first and second recognition result memories are stored in an address pointer memory. The first recognition result memory is accessed in accordance with the address pointers read out from the address pointer memory in an ascending order, and the second recognition result memory is accessed in accordance with the address pointers read out from the address pointer memory in a descending order. Coincidences between recognition candidates read out from the first and second recognition result memories and character strings of dictionary words read out from a dictionary memory are computed by a coincidence computing section. A recognition result of the input character string is obtained based on the coincidences.
