Title: Defoaming agent composition
Inventor: AIDA JIYOUJI
IPC: B01D19/04
Filed: 1982-10-07
Abstract: PURPOSE:To provide a defoaming agent effective in suppressing or defoaming a foaming phenomenon, by using fluorinated graphite and a dispersing medium therefor. CONSTITUTION:When a fluorinated graphite powder is directly added to a foamed liquid substance, it is hardly dispersed in a uniform state because of the powder and its defoaming effect is not sufficiently exhibited.

As the dispersing medium, one capable of stably dispersing the fluorinated graphite and affecting no adverse influence to the inherent properties and functions of the liquid substance may be used and, for example, org. solvents, mineral oil, animal or vegetable oil, silicone oil or fluorine oil are used. In an aqueous paint, water soluble alcohols are suitable as the dispersing medium. The mixing ratio of the fluorinated graphite powder and the dispersing medium is pref. 0.01-100: 100 on a wt. basis and the addition amount thereof to the foamed liquid substance is pref. about 0.01-5wt%.

Abstract: PROBLEM TO BE SOLVED: To provide the subject apparatus, capable of supplying necessary amount of light to a plant, small in size, excellent in space saving, inconspicuous and free from the obstruction of appreciation by placing a fixing device on an illuminant comprising an optical semiconductor. SOLUTION: A fixing device is placed directly or indirectly on an illuminant comprising an optical semiconductor (e.g. a light-emitting diode). For example, an optical semiconductor panel, etc., in which optical semiconductor lamps prepared by resin sealing of an optical semiconductor chip or by hermetic seal of the optical semiconductor chip in a container or optical chips are arranged in an area or in a line on a supporting body, is used as the illuminant. In order to increase the amount of light, a panel is suitably used since the resultant illuminant can be downsized. As the fixing device, a clip is preferable in view of handleability. In the case of indirect fixing of a device, e.g. a clip 2 is placed on an illuminant 1 through a flexible joint 5 so that the direction of the illuminant 1 can be adjusted.  Further, a red color optical semiconductor, whose wave length of emitted light is in the range of 600-700nm, is preferable as the optical semiconductor.
