  • Patent number: 6661503
    Abstract: A method of manufacturing an optic transmission module assures a high reliability for the module by inspecting the character of a low bit error rate (BER) of the module quickly and accurately. The module is employed in an optical communication system (light transmission system) required to cope with information communication systems that are becoming faster and faster in operation and larger and larger in capacity. Also disclosed is a system and a method for inspection of the BER character which uses a rectangular wave pulse as an interference light to calculate a degradation quantity of a signal-to-noise ratio (S/N) on the basis of a simple theory, thereby inspecting the BER character by extrapolating a case in which there is no interference light (S/X=∞ or X=0) with use of a sign error rate theoretical value according to a bit error rate of a light signal measured according to the degradation quantity.

  • Patent number: 5487646
    Abstract: A vacuum pump control apparatus for an evacuating-type waste water collecting system is disclosed. In the system, waste water discharged from houses and facilities is collected into a water collecting tank by vacuum sewer pipes provided with a negative pressure therein, and the waste water collected in the water collecting tank is discharged by a booster pump while the air in the water collecting tank is discharged by a vacuum pump. The vacuum pump control apparatus comprises a gas-liquid ratio detection arrangement for detecting the ratio of the amount of air to the amount of waste water to be collected into the water collecting tank, and a control system for regulating the operating time of the vacuum pump based upon the gas-liquid ratio detected by the gas-liquid ratio detecting arrangement, so that a target value of the gas-liquid ratio is recovered when it falls below the target value.

  • Patent number: 5331770
    Abstract: In a method for scraping off automatically an excessive portion of a workpiece by a cutting tool, a surface shape of the excessive portion of the workpiece is measured, a cross-sectional area variation of the excessive portion along a feed course in which the cutting tool will proceed during a cutting operation thereof is calculated from the measured surface shape of the excessive portion, and the excessive portion is scraped off in the feed course with a feed speed of the cutting tool which is changed in accordance with the calculated cross-sectional area variation of the excessive portion along the feed course, so that the larger the calculated cross-sectional area of the excessive portion is, the smaller the feed speed of the cutting tool is, and the smaller the calculated cross-sectional area of the excessive portion is, the larger the feed speed of the cutting tool is.
