Abstract: PROBLEM TO BE SOLVED: To surely make slabs during transporting catch up with each other and to join them during running by controlling the speed of the succeeding material so that the interval between the tail end of a preceding material and the tip of the succeeding material becomes a desirable one. SOLUTION: After cutting the tip of the succeeding material 12, till the restraint of the tail end of the preceding material 10 with the restraining means of a joining device 24 is completed, the speed of the succeeding material 12 is controlled so as to become the desired interval or a constant interval. On the other hand, the tail end of the preceding material 10 is cut and, after the tail end is passed through a position where the joining device 24 is started, the joining device 24 is started and its speed is raised up to a prescribed speed.  The speed of the joining device 24 is controlled so that the reference position of the joining device 24 is made to coincide with the tail end of the preceding material 10 and, when the reference position is made to coincided with the tail end of the preceding material 10, clamping of the tail end of the preceding material 10 by the restraining means of the joining device 24 is started. Until clamping is completed, tail-end positioning control of the joining device 24 is continued and, after clamping is completed, the speed control of the joining device 24 is switched.

Filed: 1992-12-03
Abstract: PURPOSE:To effectively utilize a poultry manure bedding waste and obtain a soil improving material having fertilizer effects for a long period by finely graining the bedding waste composed of a poultry manure-and sawdust, carbonizing the sawdust and simultaneously drying and concentrating the poultry manure. CONSTITUTION:A bedding waste 1 discharged from a poultry house is dried in the sun, etc., and the moisture content is reduced to some extent. The resultant bedding waste 1 is subsequently placed in a raw material pit 2 and further finely grained with a pulverizer 3. The fine granular waste 1 is then fed into a fluidized bed carbonizing furnace 4 with a screw feeder 5 and carbonized. The waste 1 introduced into the carbonizing furnace 4 is ignited with a starting burner. The sawdust in the bedding waste 1 then serves also as a fuel and the raw material to be carbonized and the carbonization is advanced while fluidizing the waste with air fed thereinto with a fluidizing blower 7. Since the fluidized bed carbonizing furnace 4 is used for the purpose of carbonizing the sawdust, the flow rate of the air and the feed rate of the bedding waste are controlled so as to regulate the temperature of the fluidized bed to about 400 deg.C.

Abstract: PURPOSE: To provide a method for processing the signal of a phase modulation type optical fiber gyro for holding a modulation factor constant. CONSTITUTION: A modulation signal output from a synchronizing signal generator 8 is input to a D-A converter 2 for rough adjustment via a phase shifter 7. A CPU 1 calculates the ratio of the quaternary harmonic wave to the secondary harmonic wave of a phase modulation frequency from the output of a lock-in amplifier 10, and controls a finely regulating D-A converter 3 and the converter 2 so that a difference from a target value becomes zero. The modulation signal regulated in proportion to the roughly regulated in the amplitude and the modulation adjusted in proportion to the finely regulated in amplitude are input to an adder 4, weighted, added and sent to a phase modulator 6 via a low-pass filter 5. As a result, the adjustment of a modulation voltage is facilitated, and a modulation factor can be controlled in a wide temperature range.
