摘要:
In a &pgr;/2 phase shifter, first and second signals and first and second inverted signals are produced based on input signals. The first and second signals have the same amplitude and are out of phase from each other, and the first and second inverted signals respectively correspond to the first and second signals with their respective phases inverted. A first output signal is produced by adding the first signal and the second signal, and a second output signal is produced by adding the first signal and the second inverted signal. Since the first and second signals have the same amplitude, the first output signal and the second output signal respectively correspond to diagonal lines of a rhombus formed by a vector representing the first signal and a vector representing the second signal. Accordingly, the phase difference between the first and second output signals of the &pgr;/2 phase shifter is accurately set to &pgr;/2 even when the phase difference between the first and second signals is not &pgr;/2.

摘要:
Between resistors 13, 14 and an NPN bipolar transistor 12 are interposed PNP bipolar transistors 21, 22 forming a current mirror 20 that uses a collector current of the NPN bipolar transistor 12 as a reference current, and determines a collector current of an NPN bipolar transistor 11. This makes possible to design a size ratio A of the PNP bipolar transistors 21, 22 so as to approximate a voltage drop &Dgr;Vb to a value close to zero, and to suppress the voltage drop &Dgr;Vb of the base voltage Vb accordingly to achieve a high power output and high efficiency when a high frequency input signal Pin increases and generates a base rectified current.

摘要:
A liquid feed containing 1.about.10% by weight of monosaccharide alone or in combination with 0.1.about.1.0% by weight of sodium bicarbonate is fed to broiler chicks, layers or breeders in the summer season, thereby preventing reduction of body weight increase rate in broiler chicks as well as reduction of egg production yield in layers or breeders, and further preventing the mortality of broiler chicks, layers or breeders caused by heatstroke. In addition a liquid feed containing 1.about.10% by weight of monosaccharide alone or in combination with 0.1.about.1.0% by weight of sodium bicarbonate is fed to layers in a later stage at an ordinary temperature or at lower temperature thereby preventing production of extra large eggs which does not meet standard requirements.
摘要:
A digital signal detection circuit includes a threshold value calculator calculating a threshold value from assumptive sampled values corresponding to various data patterns of a regenerated signal. The regenerated signal is obtained by regenerating data recorded on a recording medium by a regenerating head. The detection circuit also includes a Viterbi decoder carrying out Viterbi decoding of the regenerated signal with the threshold value determined by the threshold value calculator as a constant. The threshold value calculator variably controls the threshold value using a decoded output of the Viterbi decoder and a regenerated signal corresponding to the decoded output of the Viterbi decoder.
