Title: Fm modulator compensating modulation character channel
Inventor: KIM JONG-HAE
IPC: H03C3/08
Filed: 1991-05-23
Granted: 1994-03-09
Abstract: The FM modulator comprises a controller for providing data to assign the channel by sensing a transmitting/receiving channel and for generating a switch control signal corresponding to each channel. A frequency compensator compensates for frequency characteristics according to each channel by regulating a gain of an input channel using the switch control signal from the controller. A capacitance converter converts a given voltage value from the frequency compensator into a capacitance value. A resonator generates a given resonance frequency with the capacitance value of the capacitance converter. A voltage controlled oscillator generates an oscillation frequency to modulate the corresponding frequency based on the resonance frequency.

Abstract: PURPOSE: A semiconductor laser diode having leaky waveguide structure is provided which performs basic mode oscillation even at a wide stripe width to reduce optical power density but to increase COD level and raises a kink level through high quantum efficiency to enable high power operation. CONSTITUTION: A semiconductor laser diode includes an n-type GaAS substrate(101), an n-type InGaAlP clad layer(103) and an InGaP active layer(104) sequentially formed on the substrate, a p-type InGaAlP clad layer(105) having a stripe-shape protruded portion at the center formed on the active layer, an n-type AlGaAs lower current blocking layer(111) and an n-type AlGaAs upper current blocking layer(112) sequentially deposited on the portion of the p-type clad layer other than the protruded portion. The p-type InGaAP clad layer has a mesa structure. The current blocking layers are formed of materials having a band gap energy larger than the band gap energy of the active layer.

Title: Ultraviolet absorbing green tinted glass
Inventor: KRUMWIEDE JOHN F

Abstract: A green tinted, ultraviolet absorbing glass is disclosed having a standard soda-lime-silica base glass composition and a colorant portion consisting essentially of on a weight basis: less than 2.0% TiO2 and greater than 0.6% total iron (expressed as Fe2O3) with the ratio of FeO/total iron less than 0.35. The glass exhibits an ultraviolet transmittance no greater than 38 percent (300 to 400 nanometers) and a luminous transmittance (illuminant A) of at least 70 percent at thicknesses ranging from 0.154 to 0.189 inches.
