Filed: 1987-05-20
Abstract: PURPOSE:To adjust oscillation wavelength without increasing coupling loss and element size by isolating currents injecting carriers to an active layer and currents controlling the refractive index of a guide layer between a third semiconductor layer and the guide layer. CONSTITUTION:A semiconductor light-emitting device has structure in which it is laminated through a photoelectric-converting active layer 5, a guide layer 3, which is coupled optically with the active layer 5 and to which a diffraction grating 2 is formed, and a third semiconductor layer 4 and currents I1 injecting carriers to the active layer 5 and currents I2 controlling the refractive index of the guide layer 3 are isolated between the third semiconductor layer 4 and the guide layer 3. Consequently, the refractive index of the guide layer 3 can be controlled by currents I2 separated from currents I1 injecting carriers to the active layer 5 even in a distributed feedback laser in which the active layer 5 is positioned at the upper section (or a lower section) of the diffraction grating 2, thus allowing the adjustment of oscillation wavelength by controlling the Bragg wavelength lambdaB of the diffraction grating 2. Currents using an electrode 11 as the positive side is flowed between electrodes 11, 12 and laser oscillation in a zone in wavelength of 1.55mum is conducted, currents employing an electrode 13 as the positive side are flowed between electrodes 13, 14, and oscillation wavelength can be controlled.

Filed: 1980-09-08
Abstract: PURPOSE: To provide an electric fan, capable of producing healthy draft of air at a short period of draft repetition, by providing a brake means the braking force of which is changed with rotation of a wind-direction changing grille, and causing high-speed and low-speed rotation of the grille alternately during each one turn of  the grille.  
     CONSTITUTION: Rotation of an air flow-direction changing grille 7 is increased by an overdrive mechanism consisting of a gear train of a gear wheel 16A, pinion 17A, gear wheel 16B and pinion 17B, and causes high-speed rotation of an electrically conductive disk 19. Along with the rotation of the disk 19, magnetic flux of a permanent magnet 20 is cut by the disk 19 and dynamic brake is acted to the disk 19,  so that the grille 7 is turned at a low speed. On the other hand, along with rotation  of a main shaft 9, a short-circuit pole piece 15 approaches pole pieces N21, S22 and most of the magnetic flux is passed through the short-circuit pole piece 15. Therefore, magnetic flux passing across the disk 19 is reduced and the dynamic brake acted is also reduced, so that the grille 7 is turned at a high speed. Thus, it is enabled to cause high-speed and low-speed rotation of the grille alternately during one rotation of the same and to shorten the period of draft repetition.

Abstract: PURPOSE:To prevent the influence of noise upon a magnetic head by not only opening a switch on the input side of a motor driver but also stopping the PWM output only in the period when a reproduced envelope signal is obtained from a magnetic head and not only closing this switch but also outputting the PWM output in the other period. CONSTITUTION:Opening/closing of a switch 32 on the input side of a motor driver 18 is controlled by the switch control pulse obtained by 1/2 frequency division of the output of a head switching pulse generating circuit 34. The switch 32 is opened and the operation of PWM generators 21, 23, and 26 is stopped in a period T1 when the reproduced envelope signal is obtained from a head A, but the switch 32 is closed and this operation is executed in a period T2 when this signal is not obtained. At this time, the voltage just before opening of the switch 32 is held by a signal holding part 33, and the driver 18 is controlled by this voltage. A high frequency component included in the PWM wave is propagated in the space and is not mixed in a magnetic head 24 to improve S/N of recording and reproduced signals.

Abstract: PURPOSE:To prevent flow out of insulating resin by impregnating the insulation layer of winding with the insulating resin through vacuum pressurization or immersion, coating the outer surface thereof with powder resin and then thermally curing the powder resin. CONSTITUTION:Insulating resin 7 has low viscosity in order to enhance impregnation properties and curing time is set long in order to prolong service life. The insulating resin 7 in the insulation layer 2 is fluidal but power resin 8 adheres easily to the outer surface of the insulation layer 2 abundant in the insulating resin 7. Since the powder resin 8 contains hardener, it cures considerably earlier than the insulating resin 7 to form a seal layer on the outer surface of the insulation layer 2 thus exhibiting an effect for preventing flow out of the insulating resin 7 from the insulation layer 2.
