- a region having a relatively high potential (+ (positive)) and a region having a relatively low potential (one (negative)) are alternately formed.
- the voltages having different voltage values may be two types or three or more types. If three or more voltages having different voltage values are used, it is difficult to form an electrode pattern. Therefore, it is preferable that two voltages have different voltage values.
- the type of voltage applied to the electrode is not particularly limited, and for example, a DC voltage, a pulse voltage, or the like is preferably used.
- the plurality of electrodes may be strip electrodes in which linear electrodes are arranged at regular intervals.
- a relatively low potential [one (negative)] region and a relatively high potential (one negative) are placed on a strip-shaped electrode composed of four linear electrodes. + (Positive)) area, relatively high potential (+ (positive)) area, and relatively low potential (one (negative)) area are alternately formed on the striped electrode.

- the relationship between charged particles and the voltage polarity that gives the potential difference is relatively high potential + It is only necessary to maintain the magnitude relationship between (positive) and the voltage value that gives a relatively low potential (negative), and to set the voltage value that gives a relatively high potential + (positive) and a relatively low potential (negative).
- the polarity may be + (positive) and-(negative), both may be + (positive), or both may be one (negative). Either one may be at the ground potential.
- the fine particles may be negatively charged, and both of the voltage polarities providing the potential difference may be one (negative). In this case, the number of fine particles reaching the substrate tends to be slightly reduced, but they are arranged without being repelled by the influence of the electric lines of force. Even if the charged polarity of the fine particles is + (positive), the voltage polarity does not matter as long as the magnitude relationship of the voltage values is maintained.
- the potential of the electrodes between the electrodes on which the fine particles are arranged has the opposite polarity to the charged polarity of the fine particles, and the potential difference is further increased, so that the fine particles are made to follow the lines of electric force. In some cases, placement may be improved.
- the arrangement may be improved. For example, even if the charged polarity of the fine particles is-(negative), forming a potential difference of 100 V is more difficult than forming a potential difference of 100 V from 0 to +100 V.
- the arrangement may be better when a potential difference of 110 V between 110 V and -1000 V having the same polarity as the charging polarity is formed. This is because, when the potential difference is formed in the opposite polarity to the charged polarity of the fine particles, the fine particles are affected by the attractive force at a distance from the substrate, so the falling speed of the fine particles tends to be faster.
- the particles are formed with the same polarity, the falling speed of the particles tends to be suppressed due to the repulsive force, so that the inertial force acting on the particles changes, and as a result, the particles are affected by the electric force lines. It is thought that this is because the direction along the road changes. Since the second method for arranging fine particles of the present invention is as described above, the fine particles can be accurately arranged on the surface of the object.
- the electrodes used in the present invention are not limited to linear electrodes, and pictogram display type electrodes and the like can be used.
- a third aspect of the present invention is a method of arranging the fine particles on the electrodes by spraying the charged fine particles on an object configured by arranging a plurality of electrodes on the surface, wherein the fine particles are arranged on the electrodes.
- Spraying is performed by applying a voltage having a different voltage value to a plurality of the arranged electrodes, thereby forming a relatively high potential (ten (positive)) region and a relatively low potential (one (negative)) on the electrodes.
- the method of applying the voltages having different voltage values to the electrodes is such that the voltage values applied to the plurality of electrodes are formed based on the different voltages.

- the method of applying the voltages having different voltage values is defined as a relatively + (positive) valley (1) and a relatively one (negative) valley in the electric flux lines formed as described above.
- the relatively positive (positive) valley (1) means the valley a in (II) in FIG. In (I I) of FIG. 2, the valley has a relatively positive (positive) (1) force, which is matched with the position on the plurality of linear electrodes.
- the constant application pattern in this case is eleven.
- the fine particles are charged uniformly (negative), and the linear electrodes having the same width are arranged at equal intervals to form a strip-like electrode, and the number of relatively positive (positive) electrodes is odd.
- the fixed application pattern is, —— + —— + ——— ⁇ ⁇ , — + + + — + + + — ' ⁇ ⁇ , etc.
- the valley (1) of (positive) coincides with the position of the center of the odd number of relatively tens (positive) electrodes on the electrode, so that the fine particles are linearly centered on this electrode. Placed in
- the fine particles can be accurately arranged on the surface of the object.
- the constant application pattern is, for example, ++ — ++ — ++ —
- the rows of relatively positive (positive) electrodes form one relatively high potential (ten (positive)) region. Since the relatively one (negative) electrodes arranged form one relatively low potential (one (negative)) region, the relatively high potential (+ ( The region of positive)) and the region of relatively low potential ((negative)) are alternately arranged. However, in this case, the position of the center of the region of the relatively high potential (+ (positive)) is not always the +
- the (positive) valley (1) is not formed, but the degree of difference in electrode width
- the position of the valley of the line of electric force changes depending on the electrode spacing at that time and the regularity of the electrode width. Therefore, even when an odd number of relatively positive (positive) electrodes are arranged, the electrode width, electrode spacing, voltage application method, etc. By adjusting,-(negative) charged fine particles can be arranged at a position without electrodes. Conversely, even in the case of the above-described constant application pattern (+ is an even number), it is possible to dispose mono- (negative) charged fine particles on the electrode.

- the wet spraying method is a method of dispersing and dispersing a spacer in a mixed solution of water, alcohol, and the like. Even in this case, since the spacer is charged, the effect of the present invention is obtained. Do not spoil No. However, a dry spraying method is preferred because the larger the amount of charge of the stirrer, the better the placement accuracy. Due to the above-mentioned spraying, the spacer is charged by repeating contact (collision) with the pipe wall.
