A stage movable in the X and Y directions includes a base member, first and second moving members, and first and second rotational operation mechanisms. The first moving member is provided with a movement transmission mechanism that allows linear movement of the second moving member in a first direction and causes, when the first moving member moves in a second direction, the first and second moving members to move together in the second direction, and the second moving member is provided with a...

A gear step (1) for an actuator in a motor vehicle, in particular for a vehicle seat, comprises a housing (3) provided with a drive (1) mounted thereon in such a way that it is rotatable around an axis (A), and a driven output (21) rotatable about a second axis (B) differing from the axes (A). The drive (11) is used for receiving the driven output (21) by way of at least one rolling body (31), so that the axes (A, B) are parallelly offset by an eccentricity (E) and the driven output is driven by...

An output stage, comprising a first transistor operable to pull a voltage at an output node towards a first voltage, and a rechargeable energy store having a potential difference between first and second terminals wherein the rechargeable energy store is arranged to be controllably connected between the output node and a second voltage supply such that the voltage at the output node can be driven to a voltage outside of a range defined between the first and second voltages.

In a microscope stage device comprising a first and a second stage movable in Y- and X-direction, respectively, by means of a first and a second rotatable member operable by two handles mounted for rotation about a single shaft, there are provided first and second transmission means provided between one of the two handles and the first rotatable member and between the other handle and the second rotatable member, respectively, to adjust the amount of movement of each of the stages caused by rota...

A portable stage comprises a truck body with a fixed roof forming a main fixed panel (A) of a stage which is made by foldable side wall panels of the truck which can fold out into B, C and even D and E extensions for establishing a 30 or 40 foot or even greater width stage (using such foldable panel assemblies on either side of the truck) or fold down to an array which fits entirely within the cross section envelope or frame of the truck for over-the-road travel. The length of the stage is the l...

A portable stage is formed from a plurality of similar interlocking members having interconnecting fastening mechanisms located on the ends and sides of the stage top. Each member has a removable upper surface panel, and a plurality of foldable legs of at least two different lengths.

A puppet stage comprises a platform having a relatively large aperture therethrough and a multiplicity of support members hingedly joined to the platform at spaced locations on the periphery thereof. The support members are movable between a position parallel to the plane of the platform to a position generally perpendicular thereto, and they are securable in the perpendicular position to support the platform above them.

A turbine stage which has a stationary blade set (204) followed by a moving blade set (205) which have blades (206, 207) mounted between a floor plate (201, 211) and a ceiling plate (202, 212). The surfaces of the ceiling plate (202, 212) and/or of the floor plate (201, 211) have as their meridian lines sinusoids with the maximum for the ceiling plate (202, 212) and the maximum or the minimum for the floor plate (201, 211) located in the plane between the blade sets. The curvature of the sinusoi...

A goniometer stage has a tilting axis which can be adjusted to the point of intersection of the optical axis of the objective lens with the focusing plane. A bearing sleeve for a specimen holder rod is seated with its inner end in a ball-like inner bearing and is connected on its outer end with a cylinder of the tilting device via decoupled positioning devices. The rotational movement of the tilting device is transmitted directly, via a metal bellows from the cylinder to the bearing sleeve.
