A region division unit 30 encloses the inside of a ring-shaped discharge electrode 15 in the vicinity of that discharge electrode 15, thereby dividing the interior region of a tube-shaped vacuum vessel 11 in a direction perpendicular to the center axis Z thereof into a plasma generation region R1 and a plasma diffusion region R2, This region division unit 30 has a tube-shaped grid 301. This grid 301 has a plurality of electron passing holes and exhibits electrical conductivity. This grid 301, furthermore, is set in place concentrically with the vacuum vessel 11 so as to be positioned on the outside of a substrate W.

A surface treating apparatus has a first sheet containing unit; a second sheet containing unit; and a sheet driving unit to pull out an elongated sheet from the first sheet containing unit and move it to the second sheet containing unit as the apparatus moves on a surface to be treated. A sheet contacting member contacts one side of the sheet moving from the first sheet containing unit to the second sheet containing unit and brings the other side of the sheet into contact with the surface to be treated when the apparatus moves thereon. The elongated sheet is moved to wipe or apply wax or the like on the surface to be treated as the apparatus moves on the surface while renewing the portion of the sheet to be brought into contact with the surface when desired.

To provide a generator capable of generating plasma and ozone with high efficiency and easy to handle, with a simple structure. An electrode part 10 is formed of electrodes 11 and 12 without dielectric material interposed therebetween. An arc-extinguishing capacitor 13 as a charge storage part for storing charge is connected in series to the electrode part 10. An AC power source 15 generating plasma by causing self-arc-extinguishing discharge between the electrodes 11 and 12 by applying AC voltage to charge and discharge the arc-extinguishing capacitor 13, is connected to both ends of a circuit in which the electrode part 10 and the arc-extinguishing capacitor 13 are connected in series. The arc-extinguishing capacitor 13 and one electrode 12 of the electrode part 10 connected thereto are unitized, for making the electrode part multi-polarized. A unit is constituted of a floating electrode serving as both of the one electrode 12 of the electrode part 10 and one electrode of the arc-extinguishing capacitor 13, an insulating material provided around the floating electrode and a grounding electrode provided around the insulating material.

It is an object of the invention to provide a portable type electronic apparatus including a hinge portion having a rotating function in a plurality of directions, wherein two casings can be held stably without shaking in a state in which they are opened. A portable type electronic apparatus (101) includes a hinge portion (30) for coupling a first casing (10) and a second casing (20) in such a manner that both of the casings can be opened and closed through a first rotating axis (31) and the first casing (10) can be rotated through a second rotating axis (32) in an orthogonal direction to the first rotating axis (31). The hinge portion (30) includes a rotating structure constituting a rotation preventing unit and has such a structure that the first casing (10) and the second casing (20) can be opened and closed with a rotation around the first rotating axis (31), the first casing (10) can be rotated around the second rotating axis (32) in a state in which the first casing (10) and the second casing (20) are opened within a predetermined angle range, and furthermore, the rotation of the first casing (10) around the second rotating axis (32) is prevented in an opening state beyond the predetermined angle range, and the casings can be thus prevented from shaking.

The object of the present invention is to make possible generation of high-density plasma even in the center of a plasma generation region. A plasma generation apparatus comprises a vacuum vessel 11, gas induction unit 12, exhaust unit 13, cylindrical discharge electrode 14, high-frequency oscillators 19 and 21, ring-shaped permanent magnets 15 and 16, and two disk-shaped walls 17 and 18. The discharge electrode 14 is fashioned so as to enclose a plasma generation region 41. The permanent magnets 15 and 16 form prescribed magnetic force lines. These magnetic force lines have portions that are roughly parallel to the center axis 42 of the discharge electrode 14, the lengths of which parallel portions become longer as the magnetic force lines approach the center axis 42. The two walls 17 and 18 define the scope of the plasma generation region 41 in the dimension of the center axis 42 of the discharge electrode 14. These two walls 17 and 18 are positioned so as to sandwich therebetween the plasma generation region 41 in the dimension of the center axis 42. The plasma generation apparatus is also configured so that the magnetic force lines 43 passing through the center of the plasma generation 41 are shaped so that they do not intersect the two walls 17 and 18.

A battery holding apparatus holds a battery pack on a battery mount of an electronic device such as a portable telephone. The battery holding apparatus includes a holding member and a hook assembly. The holding member is provided on a first end of the battery mount and has formed thereon a claw fitted into a first recess formed on a first end of the battery pack. The hook assembly is provided on a second end portion of the battery mount opposite to the first end thereof and includes a spring and a protrusion. The protrusion is urged by the spring pressure produced by the spring into constant engagement with a second recess formed in a second end of the battery pack opposite to the first end thereof so as to split the spring pressure into a horizontal pressure and a vertical pressure. The horizontal pressure urges the second end of the battery pack against the holding member to eliminate any horizontal play of the battery pack on the battery mount. The vertical pressure urges the second end of the battery pack against the battery mount to eliminate any vertical play of the battery pack on the battery mount.
