Abstract: PURPOSE: To provide magnet powder, from which a magnet having a superior magnetic characteristic and high reliability can be manufactured and to provide a bonded magnet. CONSTITUTION: A quenched thin belt manufacturing device 1 is provided with a cylindrical body 2, a heating coil 4, and a quenching roll 5. At the lower end of the cylindrical body 2, a nozzle 3 which ejects molten magnet alloy 6 is formed. The quenching roll 5 is constituted of a base roll material 51 and a surface layer 52. In addition, on the peripheral surface 53 of the roll 5, gas flow passages 54 are formed as a degassing means. A quenched thin belt 8 is manufactured, through quenching and solidifying the molten alloy 6 ejected from the nozzle 3 by bringing the molten alloy 6 into collision with the peripheral surface 53 of the roll 5 in an inert gas (atmospheric gas), such as helium gas, etc. When the molten alloy 6 is brought into collision with the peripheral surface 53, though the gas infiltrates into the space between the surface 53 and a paddle 7, the gas is discharged from the space through the flow passages 54. The magnet powder is obtained by pulverizing the thin belt 8. The relation of P<D is established between mean particle diameter D μm of the powder and average pitch P μm of the flow passages 54.

Abstract: PURPOSE: A power efficient line driver with 4x supply voltage swing and active termination is provided to eliminate the need for series terminating resistors, thereby increasing the efficiency of the circuit and to eliminate also the need for external resistors or capacitors, thereby reducing the external component count. CONSTITUTION: The device includes amplifier transistors Q1, Q1', Q2, and Q240 ; resistors R1, R1', R3, R3', R4, R4', R5, and R5'; current sources G1 and G1'; transformer(22); resistance RL; temperature/process adjustment device(24); supply voltage VDD; and common node(26). Transformer(22) is a 1:1 transformer. Resistance RL represents the line impedance of a transmission line such as a coaxial cable or twisted pair. The preferred embodiment line driver achieves two times the voltage swing as compared to prior art systems which use the same transformer turns ratio. With a single ended voltage supply of 5 volts, a theoretical differential peak-to-peak swing of 20 volts is possible with this circuit. This is achieved by the transformer center tap(50) biased to the supply voltage VDD which allows the driver output at nodes(52,54) to swing on the positive supply in effect doubling its output voltage range. As the output voltage TXOUT+is pulled low by transistor Q1' transistor Q1 is driven in anti-phase and output voltage TXOUT- rises by the same amount due to the transformer effect.
