Abstract: Look-ahead control techniques and a variable attenuator are used to solve the known problem of differential attenuation of photonic intensities between time slots are delayed differently in delay paths that have different losses which optical time slot interchangers have. The result of the look-ahead control techniques and variable attenuator is a data frame in which the widely varying photonic intensities are equalized to a substantially similar level, thereby greatly reducing the bit error rate of the downstream receiver/demodulator.

Abstract: A photodetector generates an electric signal by receiving a light signal which is obtained by coupling light streams, propagated through an optical fiber sensing loop in clock-wise and counter clock-wise directions and modulated in a phase modulator.      The electric signal is detected in a synchronous detection circuit to generate a fundamental wave component of the phase modulation signal, a second harmonic wave component, a quadruple harmonic wave component, and an orthogonal component which is obtained in accordance with a phase shift of the quadruple harmonic wave component by one quarter period. In the first phase adjustment, a phase relation of the fundamental wave component, the second harmonic wave component, and the orthogonal component is maintained in a predetermined phase relation, while a relation between the phase of the components and a phase of the phase modulation signal is adjusted. At this time, a level of the orthogonal component is controlled to be zero. In the second phase adjustment, the phase of the phase modulation signal is adjusted to make a level of the second harmonic wave component zero. Subsequently, the phase of the phase modulation signal is shifted in a positive output direction by one-eighth wavelength of the second modulation signal. Then, the phase of the phase modulation signal is adjusted to make the level of the quadruple harmonic wave component zero, and the phase of the phase modulation signal is shifted in the positive output direction by the one-eighth wavelength.

Abstract: A method for controlling the temperature of injection molding machines using cross-linking polymers and molding die units using plastics. Each unit is equipped with at least one cooling channel for circulating a temperature controlling medium therethrough. The temperature of the exhausted medium is compared to a desired value and the circulation of the medium is adjusted accordingly. The method includes the steps of calculating the heat dissipation within a cycle and presetting the desired heat dissipation, prior to the start of temperature control. The temperature of the exhausted medium and the feed medium are continuously measured. The heat content WRG of the unit is determined once the unit reaches thermal equilibrium. The value WRG is stored in a subsequent cycle as a desired value based on the difference between the temperature of the exhausted medium and the feed medium during a reference cycle. The desired value is compared with the instantaneous actual value measured during all subsequent cycles. A correction value is determined based on the deviation of the heat content from the reference cycle. The temperature control impulses trigger at point Z1 and terminate at Z2 at the latest. Events Z1 and Z2 are preset by signals from the unit sequence controller.

Abstract: A novel in-bin grain drying system is the subject of the present invention. A boiler having a variable capacity Btu output heats an ethylene glycol/water heating fluid which is circulated through hydronic coils. Fans move ambient air through the hydronic coils and the dry heated air is circulated to the plenum of the grain bin. The air which enters the bin is less moisture laden than in other drying systems, particularly those which are heated by propane flame.      The temperature of the returning fluid is sensed and a fuel supply controller adjusts the amount of fuel supplied to the boiler and thus the Btu output. Accordingly the desired temperature of the air entering the plenum chamber is constant regardless of ambient outside temperature or relative humidity.
