A contactless electrical generator assembly containing a stator and a rotor located within the stator is disclosed. The stator is formed by at least one section of superconductive material and at least one electromagnetic coil. The interior surfaces of the stator preferably define a symmetrical shape. The rotor contains at least one magnetic section, and at least two nonmagnetic sections.

A gas generating device is constructed of a gas generator, a hammer pin trigger device and a gas guide slot. The gas generator has a detonator. The hammer pin trigger device has a hammer pin arranged movably toward the detonator so that the hammer pin is caused to strike and fire the detonator. The gas guide slot is formed at a joint portion between the gas generator and the hammer pin trigger device for guiding gas, which occurs upon firing the detonator, in a specific direction to an outside o...

An aerosol fogging generator is disclosed having a prime mover and blower for delivering air through a duct system to a nozzle assembly. A fluid introduction system is provided to introduce fluids into the nozzle assembly for dispersal as a fog into the atmosphere. A passage provided between the fluid introduction system and the duct system provides for a cut off of the fog produced by the generator in a matter of seconds.

An apparatus for correcting a time base of a video signal generates a clock which is phase-synchronized with a sync. signal of the video signal and has the same frequency. In a special reproducing mode, the apparatus switches an output level of a phase comparator, which phase-compares the sync. signal and the clock to a predetermined level, which is applied to a controlled oscillator and resets a frequency divider which frequency-divides the output of the controlled oscillator, in accordance wit...

A corona discharge ozone generator has an inter-electrode gap established by dielectric spacers that engage gap confronting surfaces and are distributed in the gap so that the electrodes need not be self-supporting. Also, gas flow impedance material, which can include the gap spacers, is distributed in the gap to ensure substantially uniform flow of an oxygen containing gas.

An aerosol generator specially designed for the generation of monodisperse aerosols such as calibration aerosols for the testing of measuring equipment and filters; for aerosols for making streams visible or for inhalation aerosols for medical purposes. An aerosol generator, based upon the Sinclair La Mer-principle, has been modified by inserting a nuclei removing section combined with a valve bypass between the nuclei source and the saturator.

A character generator includes a memory for storing a plurality of character patterns for each character having a specified character code, the plurality of character patterns having different writing start and end points so as to continuously couple a character pattern to the preceding and following character patterns in a string of continuous characters when the string of continuous characters are outputted, and a search unit for searching and deriving a character pattern corresponding to a su...

A pulse generator is composed of switch means to switch supply of a first current through a circuit, a first condenser connected to the switch means in series and primary charged by the first current, voltage raising means having a primary winding serially connected to the first condenser and a secondary winding to obtain voltage output by the first current, magnetic switch means of current flow switchable having a primary winding serially connected to the secondary winding of the voltage raisin...

The rotor 2 of a rotating field type turbine generator is provided with slots 3 for accommodating the field windings, wedges 4 positioned at the portions of the magnetic poles on the rotor 2 for holding the field windings and wedges 5 positioned between the magnetic poles on the rotor. These wedges 4 and 5 are constituted by metal bars without joints to enhance damper effect thereby. Magnetomotive forces due to higher harmonics, which causes temperature rise of the rotor 2 and torque ripple duri...

A ramp generator has an integrator, which provides a ramp output, and a counter, which counts a clock signal during the rise period. The counter and clock are arranged so that when the actual rise time is equal to the desired rise time, the counter overflows and returns to zero. If the rise time is too slow, the counter will contain a count at the end of the rise period. A register is connected to receive this count and an adder adds the contents of the register to the contents of the adder repe...
