DIGITAL AGC CONTROL METHOD AND FEEDBACK CONTROL DEVICE
Provided are a digital AGC control method and a feedback control device whereby appropriate feedback control is possible in response to reference input values of a variety of sizes. The digital AGC control method comprises: a first step of a digital AGC unit (11) outputting a setting value according to a reference input value (X); a second step of a PI control unit (12) deriving an operation degree of a control subject (16), using the setting value; a third step of a DAC (13) generating an output signal (Y) which denotes the operation degree; a fourth step of a gain adjustment unit (14) and an ADC (15) deriving a measurement value (M) of the control subject; and a fifth step of inputting the measurement value (M) into the digital AGC unit (11). The first step stores the reference input value (X) in a first register, stores the measurement value (M) which is inputted in the fifth step in a second register, derives a deviation between the reference input value (X) and the measurement value (M) and stores same in a third register, detects a zero value bit number which is contiguous excluding a sign bit from upper bits in the first register, left-shifts the third register according to this bit number, and generates a deviation setting value as the setting value.

Provided is a full-bridge power converter for minimizing ripple currents and common-mode noise generated when a full-bridge circuit operates. A control unit (30) generates a control signal for controlling the on-off operation of switch elements (11-14) for individual switch element, causing a switch element (11) and a switch element (12), or a switch element (13) and a switch element (14) to alternately turn on and off, and a supply current supplied from the full-bridge circuit (10) to a load (3) to be outputted. During the period when the supply current is not outputted, the switch elements (11, 13) are switched on to discharge energy stored in an inductor (16, 17) so that inertial current is drained. A filter capacitor (19, 20) absorbs the charge of the common-mode noise component generated in an output line connecting the inductor (16, 17) and an output capacitor (18).

Provided is a full-bridge power converter which operates a full- bridge circuit so as to minimize ripple current. The full-bridge power converter alternately turns the switching element Q1 (11) and the switching element Q2 (12) of a full-bridge circuit (10) on and off while alternately turning the switching element Q3 (13) and the switching element Q4 (14) on and off to output a supply current from the full-bridge circuit (10) to a load (21). The full-bridge power converter connects between the output points of the full-bridge circuit (10) to flow an inertia current by keeping both the switching element Q1 (11) and the switching element Q3 (13) in the on-state during the period the supply current is not output.

SYSTEM FOR WARNING TROUBLE WITH EGG COLLECTION QUICKLY
[PROBLEMS] A system for alarming trouble with egg collection quickly and monitoring smooth collection of chicken eggs without relying upon an existing egg collection system is needed in a multi-cage system. [MEANS FOR SOLVING PROBLEMS] An egg passage sensor system in which an egg collection conveyor is provided with an egg passage sensor, a warning means interlocked with the egg passage sensor is provided, the egg passage sensor monitors passage of chicken eggs at a time interval preset by the egg passage sensor, and, when a judgment is made that passage of chicken eggs has stopped by the monitoring, the warning means warning the stopped passage of chicken eggs operates to notify the trouble with egg collection quickly. Trouble with egg collection can be checked as finely as ensured by the number of egg passage sensors, and the system is safe because of independent operation. Unlike an integral system, operational environment does not become heavy even if a large number of systems are utilized.
