  • Patent number: 7559982
    Abstract: A dust collector (10) has a main body (12), the interior of which is divided by a tubular partition wall (26) into a central filtration chamber (30) and an outwardly-located annular cyclone chamber (32). At the upper part of the cyclone chamber (32), there is provided a water supply pipe (36) having radially directed nozzles (38) adapted to form a water film flowing down along the inner circumferential surface of the main body (12) and the-outer circumferential surface of the partition wall (26), respectively. Air to be treated is drawn under suction through an air intake (34) into the cyclone chamber (32) and swirling air is brought into contact with the water film whereby dust and particles are preliminarily collected while retaining an explosion-proof function. The cyclone chamber (32) and the filtration chamber (30) are communicated with each other at the lower portion thereof to permit the thus pretreated air to be drawn into the filtration chamber (30).

  • Publication number: 20060065645
    Abstract: A region surrounded by two gate wiring and two drain wiring includes pixels and when there is a defect of short-circuit in adjacent pixel electrodes, the short-circuited portion is removed by irradiating a laser via a mask having a transmission pattern, which corresponds to a pattern of the gate wiring, drain wiring and pixel electrodes in the short-circuited portion. The above short-circuited portion is identified and removed in comparison to a normal pattern, by use of information from an inspection apparatus, and the pattern defect formed on the substrate is automatically repaired. By applying the above method to a manufacturing process of display apparatus, in particular, to a resist pattern forming process, a display apparatus having a highly qualified display property may be achieved.

  • Publication number: 20050016953
    Abstract: A sample is processed while suppressing film deposition generated during plasma processing and fogging on a measurement window caused by etching to stably detect floating contaminants in a processing chamber with an improved contaminant capture rate. A particle detector is provided in the processing chamber, except for a space defined between electrodes of the plasma generator or a portion above the platform in which the plasma is generated. Laser light for scanning is emitted from the measurement window to the processing chamber, so that the particle detector detects scattered light from contaminants present in the processing chamber. The particle detector detects contaminants based on the detected scattered light during operation of the processing apparatus.
