摘要： PURPOSE: To surely perform communication between an information recording medium and a communication medium, even when provided in any position the information recording medium mounted on a tray, by arranging the communication medium so that a communication region covers almost a total area in a bottom part,of the tray. CONSTITUTION: A motor h35 is driven to suitably rotate an eccentric rod h37, to rotate a swivel member h31 in the counterclockwise direction and to lift horizontal stoppers h24, h25 of a stopper member h21 in the downstream. Under this condition, a tray T is loaded in endless belts h3, h4 in running, and the tray T, since its moving is impeded by the horizontal stoppers h24, h25, is placed in a stopped condition, to perform, in this position, communication between an ID tag (d) mounted on the tray T and an antenna. Since the antenna is arranged so (that its communication region covers almost a total area of a bottom part of the tray T, even when provided in any position the ID tag (d) mounted on the tray T, communication can be surely performed between the ID tag (d) and the antenna.

摘要： PROBLEM TO BE SOLVED: To provide a dobby machine capable of preventing a misrecongnition of a rotational state whether the machine rotates normally or reverses from being caused by chattering, and therefore capable of judging whether the machine rotates normally or reverses, by individually generating a color signal solely by the side of the dobby machine, without necessitating a rotation direction judgment signal nor a color request signal given by a weaving machine. SOLUTION: In this dobby machine, a rotation angle detector 70 detects a rotational state of a camshaft 11 and outputs the detected result of the rotation angle as a rotation angle detection signal 64 to a color signal judgment part 61 in a controller 61, and the controller 60 outputs a color signal 63 to the weaving machine 50. Further the controller is equipped with a normal/ reverse rotation judgment part 62 for the purpose of accurately detecting the rotational state whether the machine rotates normally or reverses when a thread breaks.

摘要： PROBLEM TO BE SOLVED: To provide a yarn winding machine which reliably prevents any vibration in a final stage immediately before the stop, and is reliably stopped in a predetermined time after starting the deceleration when controlling the deceleration and stop of a winding drum. SOLUTION: The yarn winding machine 1 comprises the winding drum 3, a motor control device 20, and a DC brushless motor 30. In the motor control device 20, the brake control by a brake control unit 24 is started when a rotational speed detection unit 23a determines that the rotational speed calculated by the drum pulse input from a rotation detector 3b reaches the brake starting speed set by an input unit 21. The brake control unit 24 repeatedly performs the control that the output is gradually reduced from the initial output value set by the input unit 21 for each edge of the rotor position detection signal of a magnetic pole position detection sensor 29, and controls the DC brushless motor 30 via an output unit 25 and a power circuit 25.

摘要： PROBLEM TO BE SOLVED: To provide a yearn heater and a yarn-heating method that can exactly control the temperature of heated yarns to a constant level with high responsiveness. SOLUTION: The yarn Y running at an almost certain speed is brought into contact with the pin heater 3 so that the yarn may be rolled around the pin heater 3. The detection results of the yarn temperature in the temperature detection signals that are output from the temperature sensor 13 are compared with the previously set target value of the yarn temperature and the control unit 11 switch-controls the switching valve 9 so that the cylinder rod 7 for the liquid cylinder 8 may be contracted or extended whereby individual yarn guides 4, 5 are allowed to move via the yarn guide supporter 6 in the axis direction of the pin heater 3. As the yarn guides move, the running way of the yarn moves toward the shaft direction of the truncated cone of the pin heater 3 whereby the distance (or time) that the yarn Y comes into contact with the surface of the truncated cone of the pin heater 3 is allowed to change and the feed of thermal energy from the pin heater 3 to the yarn Y is varied.
