Title: Wavelength variable gain equalizer and optical amplifier using same
Inventor: KENMOTSU NAOTO
IPC: G02B6/10
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To obtain gain invariably constant in flatness even if an input signal light varies in power. SOLUTION: The input signal is inputted to an optical fiber amplifier (EDFA) 2 through an input monitoring coupler 1 and amplified with the gain corresponding to the intensity of an exciting light supplied from an exciting laser light source 3. An optical detector 8 monitors part of the power of the output signal light amplified by the EDFA 2, and an output constant control part 9 performs feedback control over the exciting laser light source 3 to obtain constant output power. The power of the input signal light monitored by an optical detector 6. A temperature control 7 lowers the temperature of a heater of a wavelength variable gain equalizer 4 when the input signal power becomes small and raises the temperature of the heater when large. Consequently, the gain flatness of the output signal light becomes constant irrelevantly to the input power.

Inventor: WILBER JAMES ALBERT
IPC: H04N5/06
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To shape the waveform of pulse voltage of a booster supply circuit.

Patent JP-H0478492-A (JP)
Title: Aerator
Inventor: TSUCHIDA MASASHI
IPC: B01F3/04
Filed: 1990-07-19
Abstract: PURPOSE:To enhance the aeration performance of air and to enhance water flow-forming performance as well by projecting the end of either one tubular body of a large-diameter tubular body or small-diameter tubular body from a water surface, sinking the end of the other tubular body into the water and penetrating a revolving shaft provided with a vane part into the penetration side end of this small-diameter tubular body to regulate the flow in the same direction. CONSTITUTION:This device has a flow straighting section (a). This flow straighting section (a) acts not only to straighten the two flows by straighting flow from the suction end of the large-diameter tubular body 1 to the vane part 3 in the same direction and joining this flow with the flow from the small-diameter tubular body 2 but also to bring the respective flows in the partitioned state up to the vane part 3 without intimately mixing the air and the liquid. The air and the liquid are supplied in the state of increasing the flow velocity to the max. extent in this way and are stirred only after the air and the liquid arrive at the vane part 3, by which the aeration is effected. The flow velocity of the water flow is evidently increased by the mere presence of the flow straighting section (a) and the flow velocity of the air in the small-diameter tubular body 2 sucked by the vane part 3 is simultaneously increased by the flow velocity of this water flow. The hindrance of the flow of the air by the water flow is thus obviated.

Title: Physical property changing method by laser beam irradiation
Inventor: SATOU SHINICHI
IPC: H01L21/20
Filed: 1981-11-25
Abstract: PURPOSE:To permit a part of large area to be transformed into a single in a short period of time through an effective use of the energy of a laser beam, by changing the angle of irradiation with the laser beam. CONSTITUTION:A polycrystalline silicon film 3 is formed all over an oxide film 2 formed on a silicon substrate 1. A laser beam 10 is applied thereto to transform a desired part into a single crystal. In this case, a part of large area or a resistor required to be transformed into a single crystal long in one direction is successively scanned with the beam 10, the angle of irradiation with which is changed. By being obliquely incident on the surface of the substrate 1, a considerable amount of the beam 10 passing the polycrystalline silicon film 3 is reflected by the oxide film 2. Therefore, the amount of the beam 10 absorbed is small correspondingly, and the beam energy can be effectively used, so that it is possible to transform a part of large area into a single crystal in a short period of time.
