A miniature, two cycle engine with a linear electrical generator is presented. The piston attaches to the spring and a moving coil is also attached to the spring and/or rod assembly distal from the cylinder head. The spring is formed with an integral end fitting from one piece of preferably titanium stock. A permanent magnet is arranged where the coil moves within the magnet air gap to produce electrical power. The system operates at the resonant frequency of the spring and active mass. A glow p...

A droplet generator for generating a plurality of streams of ink droplets in a continuous ink jet printer comprises a stimulator plate, and the capability of supplying ink to the stimulator plate. The stimulator plate is substantially planar and comprises a substrate, a flexible membrane having a line of nozzles, and an actuator for vibrating the membrane at a resonant frequency. During use, a standing wave is generated such that the line of nozzles is positioned on a locus of uniform vibrationa...

A ramp generator for use in a video mixing system to produce various transition effects between edited video frames. The ramp generator produces a ramp signal R according to the equation R=Ah+Bv+C. The ramp signal R corresponds to a video frame comprised of v video lines (where v is an integer from 0 to m), each video line having h pixels (where h is an integer from 0 to n), and where A, B, and C are coefficients. Multiple ramp signals can be combined to a `solid` signal. Solid signals can be us...

A solid propellant gas generator incorporating staged gas cooling and filtration so as to generate cool, clean gases having a composition suitable for use as automobile airbag inflator.

An address generator is provided for generating addresses needed to read out data from a memory. The address generator includes a first and a second latch circuits, and a first counter connected to each of the first and the second latch circuits. The address generator also includes a first and a second storages each of which is connected to the first counter. The address generator further includes a second counter connected to each of the first and the second storages.

An electric generator is provided including a rotor having a surface with permanent magnets disposed thereon. A stator is provided having an electrical winding wound thereon in grooves in the stator. An air gap is disposed between the stator and rotor. The electrical winding of the stator is connected to a variable inductance. The value of the variable inductance is controlled by a control stage. The output of the variable inductance is connected to a rectifier which feeds direct electrical curr...

It has been determined that optical fibers possess a small amount of nonlinearity and, therefore, they are not exactly linear waveguides. This small amount of nonlinearity enables certain special pulse shapes to establish themselves and travel long distances without changing shape. These special pulse shapes are called solitons. This invention relates to a device for generating solitons by amplitude modulating an optical signal with separate in-phase electrical signals of different harmonically ...

A drive current is modulated by a current modulator, and the modulated drive current is supplied to a laser beam generator so that the laser beam emitted by the laser beam generator is varied in wavelength. The laser beam is applied to a frequency converter, and the maximum intensity of the laser beam from the frequency converter is detected by the light detector. Based on the detected intensity, the temperature of the laser beam generator is regulated by a temperature regulator. The wavelength ...

A servo controlled motor has an annular coil arrangement with meander-shaped windings and an annular arrangement of magnetic pole pairs, positioned for concentric relative rotation. A first coil is formed by a first number of the windings aligned at a first angle and with consistent pitch relative to a diameter line. A first number of pole pairs are aligned at the first angle and correspond in number and pitch to the first number of windings. A second coil is formed by a second number of winding...

An air purifying apparatus that has an ozone generator which generates plasma field in the ultraviolet region. It utilizes a pair of electrodes in the form of plates that are separated by an insulator. The plates are connected to a high-voltage transformer through diodes in such a way that only a negative and less positive charges appear on the plates. The generator is provided with a self-cleaning apparatus in which the circulating air fan that is provided for normally forcing air through the e...
