Abstract: The present inventions provides a process for producing ready-to-eat gelatin noodle which can inhibit the dissolution during the boiling step as well as the extension and the swell-up after cooking to result in producing ready-to-eat gelatin noodle which makes us feel suitable elasticity and comfortable chewing on eating it and is delicious. This ready-to-eat gelatin noodle is produced from a starting material of mixed starch which consists of potato starch and green-gram starch mixed with each other. A food base material such as carrot powder is kneaded into the mixed starch and 2 to 5 wt % of curdlan is added to the mixed starch containing the food base material. This mixed starch with the food base material contained is kneaded with water and is extruded into boiling water through a die to form lines of noodle. These lines of noodle are boiled with boiling water and then are washed with water to cool them. The thus cooled lines of noodle are frozen in a refrigerator and de-frozen.

Abstract: A process for producing instant bean-starch vermicelli (harusame) that is capable of suppressing not only dissolution during boiling but also elongation and swell after cooking, and that exhibits appropriate elasticity and gives firm palatability. This instant bean-starch vermicelli is produced from a mixed starch consisting of potato starch and mung bean starch as a raw material. In the mixed starch consisting of potato starch and mung bean starch, the content of potato starch is in the range of 30 to 70 wt. %. 0.25 to 5 wt. % of curdlan is added to the mixed starch. The resultant mixed starch is kneaded with water, and extruded into hot water through a die to thereby obtain linear noodles. The linear noodles are boiled with hot water, washed with water, and cooled. The thus cooled linear noodles are frozen in a freezer, thereafter thawed, cut into given lengths, weighed and dried by means of hot air.

Abstract: A method and apparatus for controlling a feedforward amplifier, wherein a superior distortion compensation characteristic is maintained over a wide frequency range, with the influence due to temperature variation and weathering minimized. A pilot signal generated by a pilot signal generator circuit is injected into the output of the main amplifier of a feedforward amplifier, and then the signal is sampled at the output of a first circuit and a second circuit, which is then low-range converted by a frequency converter and demodulated into I and Q components by a quadrature demodulator, and amplified and shaped into a pilot monitor signal; and a control circuit controls the vector adjusters within the distortion suppression circuit of the first and the second circuits using the I and Q signal components as the error signal so that as the amplitude level of pilot monitor signal is mininized the control value is maintained.

Abstract: A feedforward amplifier comprises a first feedforward circuit and a second feedforward circuit. The first feedforward circuit detects the distortion component of the output of a main amplifier through a first distortion detection circuit, and inserts the detected distortion component into the output signal of the main amplifier in a first distortion cancellation circuit to cancel the distortion component. The second feedforward circuit detects the distortion component of the output of the first feedforward circuit through a second distortion detection circuit, and inserts the detected distortion component into the output signal of the first feedforward circuit in a second distortion cancellation circuit, to perform distortion cancellation over a wide range of frequencies.
