IPC: H02P27/08
Filed: 1986-09-17
Abstract: PURPOSE:To conduct a pull in after the return of instantaneous service interruption quickly with a small shock by reducing the ceiling value and lower limit value of a hysteresis comparator for torque. CONSTITUTION:A voltage detector 2 is inserted on the side nearer to a DC voltage source 1 than a switch 4. Consequently, since a voltage feedback signal is effective even when the switch 4 is opened, vertual primary magnetic flux phi1 generated when the switch 4 is closed is arithmetically operated in a computing element. It is assumed that a flux command value phi1' takes a small value at that time, the switch 4 is closed after releasing service interruption. The flux command value phi1', a torque command T and the ceiling value and lower limit value of the operating point of the block 12 of a hysteresis comparator are constrained previously at small values until a pull in phenomenon is completed, and constraint is released when a pull in is finished.

Title: Monolithic semiconductor and method for control of radiated coherent radiation

IPC: G02B6/122
Filed: 1992-08-18
Abstract: PURPOSE: To improve the efficiency of an amplifier part by integrating an amplifier, together with a semiconductor laser. CONSTITUTION: A heterostructure 10 and a heterostructure 10' are integrated with each other. Since there is a boundary part 32 for separating an upper contact 30' of the heterostructure 10' from an upper contact 30 of the heterostructure 10, the operation of the amplifier part can be controlled independently of the laser part by adding a second specific bias voltage which is different from the specific voltage of the hetero structure 10. An optical waveguide 36 keeps a predetermined length over the length of the laser part. Hereby, a proper resonant cavity is ensured for the laser part. The width of an optical waveguide 36' is adapted, such that it matches with the shape of radiations emitted through the amplifier part. A semiconductor laser has a large development angle, so that the width of the optical waveguide 36' is changed along the length of the amplifier part.  Cap layers outside the optical waveguides 36, 36' become electrically resistant, owing to proton implantation for confining carriers only in the regions 36, 36'.
