Patent CA-2212383-A1 (CA)
Title: Push-in bulb base for bayonet-type bulb sockets
Inventor: SEHMER ROBERT
IPC: F21V19/00
Filed: 1996-12-18
Abstract: A push-in bulb base for use in a bayonet-type bulb socket. The push-in base does not require turning of the bulb base to engage the retaining bayonets of the bulb base in the L-shaped retaining slot of the bulb socket. The push-in bulb base has integrally formed flexible retainers which flex inward during installation and then flex back to their normal position to engage the L-shaped retaining slots of the bulb socket. An integrally formed alignment rib prevents the bulb base from being inserted into the bulb socket in a position that would prohibit the engagement of the retainer with the L-shaped retaining slot.

IPC: H04B10/2507
Filed: 1997-07-01
Abstract: A fiber optic system in accordance with the present invention includes an optical fiber, a coupling device, and a system for generating a pump signal.  The optical fiber has a birefringence which preserves polarization and has a first polarization mode which is substantially perpendicular to a second polarization mode. The coupling device couples an input signal with an input wavelength into the optical fiber so that the input signal propagates in the first polarization mode in the optical fiber. The system for generating a pump signal generates a pump signal with a pump wavelength which is within a range of 50 nanometers (nm) to 300 nm less than the input wavelength and which has a first amount of pump powe which is enough power to switch the input signal, but not enough to create higher order solitons. The coupling device also couples the pump signal into the optical fiber so that the pump signal propagates in the first polarization mode in the optical fiber. The pump signal induces a nonlinear birefringence in the optical fiber which causes the input signal to switch polarization modes and propagate in the second polarization mode, and amplifies the input signal propagating through the optical fiber. Accordingly, with the fiber optic system an input signal can be amplified and sitched concurrently, and thus separate stages for amplification and switching are not required.

Abstract: Provision of an extrusion-molded magnet using a samarium-iron-nitrogen material, which is novel and capable of exhibiting excellent magnetic properties, i.e., samarium-iron-nitrogen system magnetic particles excellent in magnetic properties.      A permanent magnet material consisting of samarium-iron-nitrogen system magnetized anisotropy particles and having increased inter-iron atom distance and elevated magnetic saturation, is prepared by a method of causing nitrogen intrusion into the iron crystal lattice of a samarium-iron alloy by holding the alloy in a nitrogen gas at about 500 degrees C. The prepared permanent magnet material is added to a thermoplastic polyolefin system synthetic resin, and the admixture is thermally fused and kneaded. The paste thus obtained is charged into an extrusion molder and extruded through a magnetic field device, which is at an end of the extrusion molder and has an internal die, thus obtaining a molded magnet, which has a particle array in a fixed orientation and is flexible. The molded magnet is magnetized with a magnetizing device in conformity to the particle array.

Abstract: The production of optical frequency reference signals by means of laser diodes and atomic transition of a diluted gas, e.g. krypton isotope 84, is known. However to do this a frequency which does not lie within the ITU table of frequency allocation is produced. In order to produce a frequency reference signal of a desired frequency, a signal is produced by a second laser diode and superimposed with the first frequency reference signal to produce a differential frequency in the microwave range. A control signal derived from the differential frequency regulates the second injection laser diode with the precision of atomic krypton isotope transition.
