Treatment agents are provided for cell seedlings. Each treatment agent comprises water, a dispersant, and activated carbon finely dispersed with the dispersant in the water. Potted seedlings can be treated by dipping them in the treatment agent and/or by irrigating them with the treatment agent. In this manner, cell seedlings can be pre-treated before planting. The thus-planted seedlings may be irrigated with the treatment agent.

It is an object of the present invention to obtain a vacuum chucking which can vacuum suck a wafer even if dusts attach thereon. The main body of vacuum chuck (101) has a plurality of block grooves (125) on the surface on which the wafer (1) is sucked and fixed, in which vacuum evacuation paths (105) each for vacuum evacuating each block groove (125) are provided for each block groove (125). When the wafer (1) is sucked and fixed under low pressure, even if the degree of vacuum in one of the block grooves (125) decreases due to attachment of dusts on part of the suction surface, or the like, the wafer (1) can surely be sucked and held.

A minute-particle iron oxide red pigment slurry is formed by adding sodium silicate to a minute-particle iron oxide red pigment slurry, and used to form a red filter formed between a phosphor layer of a color cathode ray tube and a panel thereof. Therefore, even if the red filter is brought in contact with a black matrix under the condition of a process of manufacturing the color cathode ray tube at high temperature, the red filter does not discolor the black matrix.

In a color cathode-ray tube, only a foreign matter adhering to a shadow mask is removed effectively without thermal deformation of the shadow mask or thermal denaturation of phosphors. An electron beam produced by an electron gun incorporated in a cathode-ray tube itself is scanned or irradiated to all over a shadow mask of the color cathode-ray tube. The radiant state of a fluorescent screen at this stage is checked to detect a foreign matter adhering to the shadow mask. The electron beam is deflected to align with the position at which the foreign matter is detected, and then irradiated to the foreign matter in the form of pulses. Thus, the foreign matter is heated and removed.

Method and apparatus for removing foreign matters from a cathode-ray tube

There is disclosed an electron shower apparatus which eliminates the adverse effect of a magnetic field on electrons and which provides electrons in sufficient quantity when primary electrons having low energy are employed. In the apparatus, the magnetic field generated by a filament current is decreased or eliminated by pulsing the filament current or by passing a current opposite in direction to the filament current in the vicinity of the filament current.
