摘要： Data transmitted from a local terminal to a remote terminal is converted into such a diphase data signal that a data bit of binary "0" is represented by a signal with two transitions, and a data bit of binary "1" is represented by a signal with one transition. Data transmitted from the remote terminal to the local terminal is modulated by the diphase data signal of the local terminal, and delivered to the local terminal in the form of a diphase data signal. In the local terminal, the coded diphase data signal from the remote terminal is demodulated by the diphase data signal of the local terminal, and regenerated into the transmission data of the remote terminal.

A stator (10) is formed by inserting each of the core back iron cores (12) into a space between the tooth-shaped iron cores (11, 11) adjacent to each other. The present invention also provides a stator in which a packing factor can be increased and the magnetic flux can be made smooth, and a manufacturing method therefor.

摘要： A method of securing a stator winding such that it has improved heat dissipation performance includes steps of inserting a stator winding into a stator core soaking these components in a varnish tank while being held together as one, and after the varnish has soaked into the stator winding 15, withdrawing the winding and core from the varnish tank. Then a mandrel comprising an outer peripheral pressing portion made by wrapping a fluororubber around an outer periphery of a mandrel body made of a fluoroplastic, is inserted into the stator winding. After this, the varnish is heat hardened with the stator core, the stator winding, and the mandrel 33 all held together as one. In so doing, the outer peripheral pressing portion is deformed with irregularities replicating the inner periphery of the stator winding 15. Hence on the inner peripheral side of the stator winding, the varnish resin hardens with the irregularities retained. As a result, the effective inner peripheral surface area of the stator winding with the hardered varnish is increased, and heat dissipation is thus improved.

摘要： A stator of an electric motor includes coil cores, bobbins and coils. The coil cores include six coil cores, which are arranged at equal angular intervals in a circumferential direction. The bobbins respectively cover outer peripheral surfaces of the coil cores, and the coils are respectively wound around outer peripheral surfaces of the bobbins. Among the six coils, each diametrically opposed two coils are electrically connected to each other through the corresponding connection line. Positioning members displace positions of the connection lines from one another, so that interference between the connection lines and interference between the connection line and the coils are limited.

摘要： The stator includes core back iron cores disposed on outer circumferential sides between a plurality of teeth iron cores disposed at regular intervals of a predetermined distance in a predetermined circumferential direction. A stator winding is disposed on inner circumferential sides between the plurality of teeth iron cores. The stator winding is constituted by a plurality of wire bundles each of which is a bundle of a predetermined number of electric wires and which are connected in parallel with one another. The wire bundles are set so that the number of electric wires constituting a wire bundle located on the inner circumferential side between adjacent teeth iron cores is smaller than the number of electric wires constituting a wire bundle located on the outer circumferential side. Hence, the ratio (L/A) of the circumferential length L of each wire bundle to the sectional area A thereof is set at a value in a predetermined allowable range.

摘要： An integrator consisting of a high gain D.C. amplifier, a voltage-current converter such as a resistor, and a feed-back capacitor. An unknown analog input voltage to be converted and two known reference analog voltages which have the same polarity as that of the input voltage to be converted are supplied to the voltage-current converter in the integrator through a first switching circuit having three switches. The output voltage of the integrator is supplied to a comparator. The comparator compares the integrated voltage with a fixed reference voltage and produces an output signal when both voltages are equal. A second switching circuit including one switch, a third switching circuit including two switches, and two capacitors respectively connected to the switches in the third switching circuit are provided between an output terminal of the integrator and ground. A voltage-current converter such as a resistor or a transistor circuit is connected between the input terminal of the D.C. amplifier and the interconnecting point of the second and third switching circuits. Each switch in the first, second and third switching circuits, is controlled by a switch control circuit. The switch control circuit includes counters, flip-flops, calculating circuits and delay circuits. A voltage corresponding to one of the two known reference voltages is stored in one of the two capacitors connected to the ground and a voltage corresponding to the other known reference voltage is stored in the other capacitor connected to the ground. A combined voltage of the input voltage and the voltage stored in one of the two capacitors and a combined voltage of one of the reference voltages and the voltage stored in the other capacitor are respectively integrated by the integrator. As a result thereof, a digital quantity representative of the ratio of the unknown input voltage and the difference between the two reference voltages is obtained by the switch control circuit.
