Abstract: PURPOSE: To optimally suit a device for detecting a pattern to the respective patterns. CONSTITUTION: In order to scan sewing materials 11a and 11b in an intended sewing direction for length at least same as the repetition length of the pattern, sensor systems 10a, 10b, 12a and 12b are separated before starting a sewing process during an adjustment stage, and adjustment is performed to a value for maximizing an amplitude change area by at least one of the operation parameters of a pattern sensor for determining the modulation area of detection signals during the adjustment stage. In order to clearly separate the detection signals before and after the sewing material reaches a scanning position, an optical detector is specially provided, and the detector releases a step or a device for offset and/or amplitude adjustment when the sewing material reaches the grasping position of the pattern sensor first.  By this method, it is guaranteed that only signal fluctuation by the pattern is counted in and a signal value generated in the case that the sewing material is absent is not counted into an adjustment standard.

Abstract: PURPOSE:To speedily decide a weighting factor by simplifying an operation by means of inputting the form of a weighting function in the sequence of points, stabilizing control performance by means of an interpolation arithmetic and using a table. CONSTITUTION:An object to be controlled 5 is set to be a motor and a control rule 1 is to be PID control and a control rule 2 to be fuzzy control. The weighting factor alphais defined as the function of DELTAtheta and DELTAtheta '. The weighting factor is stored in RAM in an input part 8 by a coordinate point. When data is inputted from the input part 8 in the sequence of points, an interpolation arithmetic part 7 interpolates a straight line and obtains the weighting factor alpha with respect to respective input values. The obtained factor alpha is stored in a table 6. The operation is executed before the device is operated. The corresponding weighting factor alpha is read from theta and theta ' inputted at the start of the operation in the table 6, the outputs u1 and u2 of the control rule are multiplied by alpha and 1-alpha, they are added and a manipulated variable (u) is outputted to the motor 5. When DELTAtheta and DELTAtheta ' are small, the weighting factor which can withstand the fluctuation of a load can be decided at high speed if the weighting function is set so that the weight of fuzzy control becomes large when PID control is small.

Abstract: PURPOSE:To enable improvement of heat recovery efficiency, by a method wherein, in a thermal equipment, e.g., steel piece heating furnace, a heat transfer pipe is rotatably installed, and the sectional area of a second fluid passage is changed. CONSTITUTION:Combustion exhaust gas, being a second fluid, flows in a direction extending at right angles with a shaft between heat transfer pipes 6 of recuperator 4, first fluid outgoes from an upper case 5a on the downstream side of the recuperator 4 through a pipe 6, a lower case 5b, a heat transfer pipe 6 on the upper stream side to the upper case 5a, and the air for combustion is preheated. A pressure in a heating furnace 1 is detected by a pressure sensor 10, a detecting pressure, inputted to a furnace pressure control device 9, is compared with a previously set reference pressure to compute and output a driving signal required for production of the reference pressure, and a driving device 8 drives opening and closing of the heat transfer pipe 6. Since the heat transfer pipe 6 is formed in the shape of an oval and such that the more a furnace pressure is decreased, the more an exhaust gas flow passage is closed, a velocity of flow of exhaust gas from the recuperator 4 is adjusted to a given value, and heat transfer efficiency and in its turn heat recovery efficiency can be held to higher than a given value. When a flow rate of exhaust gas is low, the velocity of flow of exhaust gas can also be held to hold a pressure loss at a preset value, and a pressure in the furnace can be held at a specified value.
