Ultrathin high-power direct current magnetoelectric motor

The invention discloses an ultrathin high-power direct current magnetoelectric motor, comprising a transmission shaft, a discal stator component sleeved at the middle section of the transmission shaft, discal rotor components which are respectively arranged at the two sides of the stator component and rotate with the transmission shaft, and an upper end cap and a lower end cap which are respectively arranged at the two sides of the rotor components. The stator component comprises a discal stator frame, a plurality of fan-shaped grooves which are arranged on the stator frame in a ring form, fan-shaped windings arranged in the fan-shaped grooves, and inner clamping rings and outer clamping ring for fixing the fan-shaped windings. The rotor component comprises a rotor plate fixedly connectedwith the transmission shaft, fan-shaped grooves which are arranged on the rotor plate in a ring form, and permanent magnets fixed in the grooves. The surface of the rotor plate, which provided with the permanent magnets, faces the fan-shaped windings. The motor of the invention has the advantages of higher efficiency and energy saving, and the manufacturing, the assembling and the maintenance of the stator winding are more simple, convenient and reliable.

III-V charge coupled device suitable for visible, near and far infra-red detection

A photon detector is obtained by using the intersubband absorption mechanism in a modulation doped quantum well(s). The modulation doping creates a very high electric field in the well which enables absorption of input TE polarized light and also conducts the carriers emitted from the well into the modulation doped layer from where they may recombine with carriers from the gate contact. Carriers are resupplied to the well by the generation of electrons across the energy gap of the quantum well material. The absorption is enhanced by the use of a resonant cavity in which the quantum well(s) are placed. The absorption and emission from the well creates a deficiency of charge in the quantum well proportional to the intensity of the input photon signal. The quantity of charge in the quantum well of each detector is converted to an output voltage by transferring the charge to the gate of an output amplifier. The detectors are arranged in the form of a 2D array with an output amplifier associated with the entire array or a row of the array as in the known charge coupled devices, or a separate amplifier could be dedicated to each pixel as in the known architecture of the active pixel device. This detector has the unique advantage of near room temperature operation because the dark current is limited to the generation across the semiconductor bandgap and not the emission over the quantum well barrier. The detector also has the advantage that the readout circuitry is implemented monolithically by the HFETs formed in the GaAs substrate simultaneously, with the detecting elements.
