Abstract:
A method for the electron-microscopic observation of a semiconductor arrangement is provided. It includes providing an electron microscopy optics for imaging secondary electrons emanating from the semiconductor arrangement within an extended object field on a position-sensitive detector, providing an illumination device for emitting a primary energy beam, directing the primary energy beam to at least the object field for extracting there secondary electrons from the semiconductor arrangement. The semiconductor arrangement comprises a region with an upper surface provided by a first material and a recess with a high aspect ratio which is surrounded by the upper surface and has a bottom provided by a second material.
Abstract:
An airbag, particularly for the knee or head region of a vehicle occupant, has a substantially cylindrical main region. The airbag comprises a substantially cylindrical fabric tube whose lateral ends are stitched after folding the tube into a predetermined pattern having at least two looped segments. The fabric tube can be formed by joining the lateral edge of a rectangular fabric blank.
Abstract:
A massaging apparatus (1) comprises a housing (5) having an upper wall (4) and side walls (5, 6, 7, 8) and a bottom wall (9), and massaging means (10) in the area of the bottom wall (9), which massaging means (10) are movable over a body area of a person, which massaging apparatus (1) comprises handling means (29) for holding and guiding the apparatus when the massaging means (10) are moved over a body area, which handling means comprise at least a part of the upper wall (4) of the housing (3) and, in addition, at least one strip-like handle member (30), such that a hand can be inserted at least partly between the handle member (30) and the upper wall (4) of the housing (3), the handle member (30) being preferably constructed so as to be elastic, soft, extensible in its longitudinal direction and continuously adjustable, and consists of a core (51) of a soft material and of a sleeve (52) of a material which is mild to the skin and which surrounds the core (51).
Abstract:
In a massaging apparatus (1) comprising a suction chamber (12) bounded by chamber walls (13, 14, 15, 16) and a pump (19) for the generation of a partial vacuum inside the suction chamber (12) and thus forming a skin fold (20) which is drawn into the suction space inside the suction chamber (12), as well as two rollers (21, 22) to be placed onto a body area (3), the two rollers (21, 22) can be driven by a motor (27) via a drive transmission (28), and the roller (21) which is disposed at the front, as viewed in the operating direction (4), is arranged inside the suction chamber (12), and the roller (22) which is disposed at the rear, as viewed in the operating direction (4), is arranged outside the suction chamber (12), the circumferential surface (25) of the roller (21) which is disposed at the front, as viewed in the operating direction (4), advantageously consisting of a material having a friction value higher than that of the material of the roller which is disposed at the rear, as viewed in the operating direction (4).
Abstract:
a massaging apparatus (1) having a suction chamber (17) and having a pump (41) for the generation of a partial vacuum in the suction chamber (17) the pump (41) is mounted on a support (9) of the massaging apparatus (1) with the aid of elastic mounts (64, 65) and first noise reduction means (70) have been provided upstream of an inlet (50) of the pump (41) and second noise reduction means (71) have been provided downstream of an outlet (51) of the pump (41).
Abstract:
The invention relates to a nasal cannula for an anti-snoring apparatus, comprising a forked tube pneumatically connected to apertures, which are embodied and positioned in such a way that air can be administered into the nose of a user via these apertures. The nasal cannula further comprises a heating wire extending in the interior of forked tube in such a way that the heating wire can heat the air supplied through the forked tube. The invention moreover relates to a nosepiece and to a Y-shaped element for nasal cannula including internal radius steps at tube connection points. The invention further relates to a nosepiece and to a Y-shaped element having rounded off transition regions. The invention finally relates to a method for avoiding condensation in nasal cannulas. To this end, the gas is heated as it flows through the tubes of a nasal cannula.
Abstract:
A massaging apparatus (1) comprising a housing (5) having a bottom wall (11) and a suction chamber (12) bounded by chamber walls (13, 14, 15, 16) and a pump (19) for the generation of a partial vacuum inside the suction chamber (12) and thus forming a skin fold (20) which is drawn into the suction space inside the suction chamber (12), as well as at least one roller (21, 22) to be placed onto a body area (3), comprises at least in an area of at least one wall (14), preferably a chamber wall (14), an apparatus part, preferably two cylinders (32, 33), which is movable with respect to this chamber wall (14), and these cylinders (32, 33) are movable, i.e. rotatable, with respect to the chamber wall (14) by the skin of the skin fold (20) drawn into the suction chamber (12), which results in only a comparatively low friction between the chamber wall (14) and the skin of the skin fold (20).
Abstract:
The invention relates to a delivering unit for gas, comprising a compressor (101) in a noise-insulation housing (20, 40), which comprises an inlet opening (27, 66) and a blow-out opening (24, 69, 70). An inlet tube (96) can pneumatically connect the inlet opening to the inlet of the compressor. An outlet tube (96) can connect the blow-out opening to the outlet of the compressor. A noise absorber (60, 80) having an inlet chamber (73, 97) and an outlet chamber (74, 98) may be accommodated in the noise-insulation housing. Neoprene may be used as lining for the inner walls of the noise-insulation housing. Sheets (131. 133) may be provided between the noise-insulation housing and the compressor. An inner heat sink (42) and an inner blower (48, 49) can cool the compressor. A heat sink (41) may form one side (40) of the noise-insulation housing. An outer blower (7) can cool the heat sink. Blind tubes can be used both at the inlet and the outlet, so as to suppress tonal sound. Moreover, the invention relates to corresponding delivering methods.
