Title: Curved tube type fluorescent lamp
Inventor: EBARA HIROYUKI
IPC: H01J61/48
Filed: 1981-10-21
Abstract: PURPOSE:To improve light output and the strength of an airtight container by changing the structure of a coat containing a phosphor that is applied on the inner surface of the transparent airtight container. CONSTITUTION:The first coat applied on the inner surface of an airtight container uses a mixture of a single material or a number of materials that are selected from calcium pyrophosphate, aluminum oxide, and magnesium oxide and an antimony and manganese activated calcium pyrophosphate as the main body. The weight of a single material or a number of materials selected from the said calcium pyrophosphate, aluminum oxide, and magnesium oxide is from 5 to 82 weight % of the gross weight for the mixture of the said first coat. The second coat with the main body of a phosphor that emits higher efficiency light than that from the phosphor containing the said first coat is applied on the said first coat. As a result, since the effect of an alkali such as sodium or the like that is deposited from the transparent airtight container can be eliminated when the transparent airtight container is heated and worked, light output characteristics such as initial luminous flux, luminous flux holding rate or the like can be made excellent.

Abstract: PURPOSE:To prevent movement of an aqueduct after an avalanche of sand and stone is captured by a method wherein the position of a beam between the columns of the central part of a permeation part of which a weir is composed is lowered to a level lower than that of a beam between other columns and by a distance shorter than a distance between the columns 1. CONSTITUTION:The position of a steel pipe beam 2 between steel pipe columns 1 at the central part of a permeation part of which a permeation type weir is composed is lowered to a level lower than that of a beam 2 between other columns 1. The position of the steel pipe beam 2 at a topmost stage between the steel pipes column 1 is gradually raised to a level higher than the position of the beam 2 between the columns 1 at the central part of the permeation part from the central part toward both sides. And the beam 2 is arranged by a distance shorter than a distance between the columns 1 below the beam 2 at a topmost stage between the columns 1. This constitution pushes out a larger quantity of stone gravels, accumulated at the beam 2 at the central part, of relatively smaller stone gravels subsequently accumulated on stone gravels having a maximum size captured by the weir, causes centralization of flowing water to a central part, and ensures an aqueduct.
