摘要： PURPOSE:To eliminate the possibility of breakage of wire or inferior insulation by delivering an output from a control amplifier for controlling a finger part drive actuator, to the latter by way of a cushion circuit. CONSTITUTION:The opening and closing condition of an actuator 20 is monitored by a speed or position detecting means 22, the actuator is driven with a light force by a control means 24 for the actuator 20 until a finger part 3 clamps a wire W. After a detecting means 22 detects the clamping of the wire W by the finger part 3, the drive force of the actuator 20 is gradually increased up to a final wire clamping force in accordance with a detection signal from the detecting means 22. As a result, the wire W clamped by the finger part 3 is gradually pulled with no an abrupt tension being exerted thereto, thereby it is possible to eliminate such a disadvantage that the wire W wedges into a head edge.

摘要： PURPOSE:To obtain a winding machine, which can operate an inserting means stably at a high speed, by positioning the rotary center, at which the inserting means holds a piece of wire and starts inversion, to the side of a body to be wound farther than the wire holding position. CONSTITUTION:A piece of wire A, which is extended from an inserting means on one side, is pulled to a pulling means 26b through a wire hole 22a of a body to be wound 22. Specified tension is imparted to the wire A. The pulling means 26b is retreated in the seperating direction from the body to be wound 22. At this time, the body to be wound 22 is inverted. Thereafter, an inserting means 32b on the same side as the pulling means 26b is made to advance on the line of the wire A, And the wire A is held. The wire A is disconnected from the pulling means 26b. The inserting means 32b is inverted. Thereafter, the disconnected end of the wire A is inserted into the wire hole 22a of the body to be wound 22. Above described steps are repeated. The rotary center B of said inserting means 32 in this winding machine, at which the wire A is held and the inversion is started, is positioned on the side of the body to be wound 22 farther than the wire holding position.

摘要： PURPOSE:To make it possible to tightly wind a wire around the body to be wound such as a core and the like when a winding work is conducted automatically by a method wherein, after the body to be wound has been once inclined in the direction reverse to the direction in which the wire is wound, the body to be wound is inverted to the winding direction of the wire. CONSTITUTION:The suction means 26b, into which the tip of the wire A is sucked, is moved backward by a servo motor 18b in such a manner that it is moving away from a core 22, and at this time, the wire A is softly pinched by closing a squeeze member 30, the prescribed tension is given to the wire A, and the tendency of the wire A that it is easily bent is removed. A holder 20 rotates 180 deg. when the suction means 26 moves backward, but the holder is held for an appropriate period at the position which is inclined at a suitable angle (45 deg. for example) in the direction opposite to the direction in which the wire is wound while tension is added to the wire A. As an obtuse angle is given to the wire A at the position corresponding to the corner part of the core, it does not become loose by contacting to the corner part, and it is tightly wound on the core 22.

摘要： PURPOSE:To readily establish a voltage with a simple structure by connecting a positive temperature coefficient thermosensitive resistance element in parallel with a field current controller. CONSTITUTION:When an AC generator 10 is started, a weak voltage is induced in the generator 10 by the remaining magnetic field of a field 18. Since a positive temperature coefficient thermosensitive resistance element 36 has very small resistance value at the ambient temperature, a current is flowed to the field 18 and the element 36 even if the output terminal voltage of a rectifier 16 is ultrafine, thereby increasing the output voltage V of the generator 10. If the output voltage V becomes the voltage or higher required for operating a controller 34, the controller 34 starts operating, and a field current is controlled to hold the prescribed voltage. On the other hand, the element 36 is self-heated by the flowing current to abruptly increase the resistance. Thus, a current is not almost flowed to the element 36. Thus, the voltage is reliably established readily.

摘要： PURPOSE:To achieve high response, by limiting variation of output from a speed control amplifier when the difference between an output integrated with a predetermined positive or negative voltage corresponding to the polarity of output from a speed control amplifier and an output from the speed control amplifier exceeds over a predetermined level. CONSTITUTION:A speed control amplifier 18 obtains a difference v between a setting speed v0 and a speed v, and provides the difference v to a current control amplifier 24. An integrating circuit 50 integrates a constant voltage corresponding to the polarity of the output v from the speed control amplifier 18. When the difference ¦b-c¦ between an output (c) which inverted the polarity of the output v and an integrated output (b) exceeds over a bias voltage VB, comparators 72, 74 output a positive or negative voltage. Consequently, variation of the output v from the speed control amplifier 18 is limited, and high response can be obtained.

摘要： PURPOSE:To permit energy economization by installing a flow-rate variation detecting means and allowing a pump to stop when the amount of use of water reduces and reaches a set value and starting the pump again when the water-feeding side pressure reduces to the set value after the pump stops, in the control for a variable-speed pump with which a constant discharge pressure can be obtained. CONSTITUTION:When a pump 11 is driven by a motor 14, the flow rate in a water feeding pipe 12 gradually increases, and the pressure increase in the water feeding pipe 12 is detected by a pressure detector 16. This pressure signal is compared with a set pressure H1 set by a pressure setting device 15 in a PI control part 13, and the number of revolution of the motor 14 is controlled through a variable speed change gear 17 so that the above-described deviation becomes zero. When the amount of use of water reduces, and the pressure in the water feeding pipe 12 increases, the number of revolution of the pump 11 reduces. Further, when the speed signal of a motor-speed detector 19 lowers to the set value set by a setting device in the first signal detector 18, a pump stop signal is output from this detector 18, and the motor 14 is stopped.

摘要： PURPOSE:To provide a thyristor phase control system controlling a thyristor Leonard device, etc., with high resolution, accuracy, and response without increasing the load of a microprocessor even when a plurality of thyristor bridge circuits are subjected to phase control. CONSTITUTION:A phase detector 31, an LPF 32, a VCO circuit 33, and a pulse generator 5 constitute a PLL circuit. A timer 51 counts a VCO output clock CLK, a comparator 52 detects coincidence of the counted value and the timer value which is set by a CPU 6, and a command decoder 55 outputs an interrupt request signal INT to the CPU 6. The CPU 6 sets a next control command to a command register 54 at each input of the interrupt request signal INT. A pulse PP obtained by dividing the clock CLK with a frequency-dividing ratio corresponding to the timer value which is set by the command decoder 55 or the CPU 6 is output to the phase detector 31 and is subjected to phase comparison with a power supply pulse ACP. A control angle alpha which is output to an SCR selection port 7 from the CPU 6 using a gate pulse GP is applied to the gates of corresponding SCR 11-16.
