Abstract: The plasma processing apparatus M2 has a first and a second elongate electrodes 30, 30. A processing gas is introduced from a first aperture 30b formed between upper first edges of the electrodes 30, 30 into a gap 30a between the electrodes 30, 30. An electric field is applied and a plasma is generated between the electrodes 30, 30. The processing gas is blown-off from the gap 30a through a second aperture 30c formed between lower second edges of the electrodes 30, 30. A first side surface on the first edge of the first electrode 30 is covered by an insulative cover 22 including a cover main body 22A and a plasma-proof member 26 which is formed of an insulative material which is higher in plasma-proof property than the cover main body 22A. The plasma-proof member 26 forms a processing gas introducing hole which is continuous with the first aperture 30b. The plasma-proof member 26 is contacted with the first side surface.

A processing gas is introduced from a first aperture formed between upper first edges of the electrodes 30, 30 into a gap 30a between the electrodes 30, 30. An electric field is applied and a plasma is generated between the electrodes 30, 30. The processing gas is blown-off from the gap 30a through a second aperture formed between lower second edges of the electrodes 30, 30. An insulative spacer 60 is disposed in the gap 30a so as to be interposed between the electrodes 30, 30 substantially at an intermediate section in the longitudinal direction of the electrodes 30, 30. The spacer 60 prevents the electrodes 30, 30 from being deformed to narrow the gap 30a between the electrodes 30, 30 due to the Coulomb force, etc.

Abstract: A plasma processing apparatus M1 is provided with a processing part 20 for supporting a pair of elongate electrodes 30. The processing part 20 is provided with a plurality of pull bolts 52 (approach-deforming preventers) mutually spacedly arranged in the longitudinal direction of the electrode 30. A head part of each pull bolt 52 is hooked on a rigid plate 33 through a bolt holder 53, and a leg part thereof is screwed in the electrode 30. Owing to this arrangement, the electrodes 30 can be prevented from being deformed by Coulomb's force.

Abstract: A serial printer comprises a printing head, a carrier for carrying the printing head, a platen, and a pair of guide members extending in parallel with the platen for supporting the carrier in a movable manner. An openable member is attached openably to the casing of the printer and supporting one of the guide members. Engaging receivers are formed in the carrier for allowing the one guide member to engage therewith and disengage therefrom in a direction substantially perpendicular to the extending direction of the one guide member. Engaging brackets may be mounted on the printing head for coming into and out of engagement with one of the guide members at a right angle with respect to the extending direction of the one guide member. Moving members may be supported movably in the casing of the printer for supporting the one guide member, when moved, to bring the one guide member into and out of an engagement with the engaging brackets.
