Abstract: A Vacuum Diode is constructed in which the electrodes of the Vacuum Diode are coated with a thin film of diamond-like carbonaceous material. The cathode and anode are separated by spacers and a rinse-able material, the rinse-able material which is later removed. Carbonaceous films and the related process for producing a thin film of ablated diamond are not previously known in connection with Vacuum Thermionic Converters, and provide a practical and improved means of constructing such devices.A Vacuum Thermionic Converter is optimized for the most efficient generation of electricity by utilizing a cathode and anode of very low work function. The relationship of the work functions of cathode and anode are shown to be optimized when the cathode work function is the minimum value required to maintain current density saturation at the desired temperature, while the anode's work function is as low as possible, and in any case lower than the cathode's work function.

Abstract: A multiple cell thermionic converter having a generally tubular member of electrically conductive refractory metal with an internal cavity and a tubular envelope of electrically conductive refractory metal disposed in surrounding relationship to such generally tubular member. Electrically insulating ceramic material is disposed upon sections of facing surfaces of the envelope and tubular member, which is in the form of a body that has a central zone of plasma-sprayed refractory metal oxide selected from the group consisting of scandia, hafnia, zirconia and alumina, and a pair of flanking outer zones made of mixtures of the refractory oxide and particulate refractory metal. Refractory metal electron emitters and collectors are supported upon the ceramic bodies and juxtaposed in pairs with an annular gap therebetween to form a plurality of thermionic cells.

Abstract: A synchronous linear motor with primary part having a winding and a secondary part including an elongated bearing plate to which the pre-magnetized permanent magnets of brittle and corrosion-prone material, are firmly adhesively secured while maintaining the pole pitch grid. In order to be able to securely bond the pre-magnetized permanent magnets to the secondary part economically and with high precision, it is proposed that spacers (2,3) corresponding to the pole pitch grid of the synchronous linear motor be arranged between pre-magnetized permanent magnets (4).

Abstract: A linear actuator powered by a Lorentz force. The force is generated by passing an electrical current through an armature spanning a space across a magnetic field established between two permanent magnets. The armature is mounted upon a slider extending between a pair of electrically conductive rails. Reversible linear motion is achieved by switching the polarity of an electrical potential applied across the two rails.

Abstract: A motor support apparatus is provided which supports an output shaft of a motor used to operate a pump. The motor support apparatus includes a support housing, a bearing chamber formed in said support housing, a bearing member for bearing an output shaft of a motor. The bearing member is disposed within the bearing chamber with a given clearance between itself and an inner wall of the bearing chamber. A spring is provided so as to produce an eccentric spring load acting on the bearing member so as to decrease the given clearance for retaining the bearing member tightly within the bearing chamber in order to suppress mechanical vibrations generated during a motor operation.

Abstract: Disclosed is an AC electric motor with oscillating rotary output, a permanent magnet rotor having radially magnetized magnets, and feedback control of oscillation amplitude. Amplitude control is accomplished without a separate amplitude sensor by using an accurate model of the motor as a basis for calculation of amplitude from measurements of motor voltage and current. The motor has high efficiency, low inertia, and uses a relatively small volume of permanent magnet per unit power output.
