A compact plasma generating apparatus providing high efficiency of plasma excitation is presented. A plasma generating apparatus (100) comprises a microwave generating apparatus (10) for generating microwaves, a coaxial waveguide (20) having a coaxial structure comprising an inner tube (20a) and an outer tube (20b), a monopole antenna (21) being attached to one end of said inner tube (20a), for directing the microwaves generated by said microwave generating apparatus (10) to the monopole antenna (21), a resonator (22) composed of dielectric material for holding the monopole antenna (21), and a chamber (23) in which a specific process gas is fed for plasma excitation. The chamber (23) has an open surface and the resonator (22) is placed on this open surface, and the process gas is excited by the microwaves radiated from the monopole antenna (21) through the resonator (22) into the interior of the chamber (23) to generate plasma.

A protective and / or splint device, for example a distal radial splint device (200), comprises a protective and / or splint member (201) and a spacer member (13). The protective and / or splint member (201) comprises a composite protective and / or splint material and is formable at a forming temperature and is substantially rigid at ambient temperature. The material comprises a polycaprolactone and a ligno-cellulose additive material. The protective and / or splint member (201) comprises a mesh of elements (202), with a plurality of openings (203) through the protective and / or splint member (201). Away from the periphery of the splint member (201), the openings (203) are diamond-shaped. Two border elements (204) extend along the two sides of the periphery of the splint member (201). The three point bending strength to openness ratio of the member is greater than 0.1 and the unidirectional bending strength to openness ratio of the member is greater than 4. This results in a device (200) with sufficient strength, which is breathable with open surfaces, and the volume of material used is optimized. The strength of the member (201) parallel to the longitudinal direction of the arm is greater than the strength parallel too the circumferential direction. At the forming temperature the member (201) is stretchable. The member (201) is rounded between the outer surface of the member (201) and the edges around the openings (203).

In a casing unit for accommodating a printed circuit board, a case has a plurality of walls, one of the walls being partially or entirely open to form an open surface through which the board is inserted into the case. Guides, secured on side walls, comprise two guide protruding members each formed to protrude from the side walls and positioned to partly contact both sides of the board to be inserted into the case, whereby the board is positioned in a planar direction thereof. A cover, applied to the case to cover the open surface of the case, comprises a vertically positioning member positioning the board in a vertical direction, when the cover is applied to the case to cover the open surface, by pinching an end of the board in the vertical direction. The end of the board is located in the open surface of the case.
