A cylindrical pin (1) for connecting and/or guiding components (A, B), particularly in tool, fixture, and machine construction is provided. In order to make the cylindrical pin yieldable in a radial direction and thereby allow for compensation for its manufacturing tolerance, the cylindrical pin is provided with an internal bore (4, 6) extending in the axial direction at least over a partial region (1a, 1c) of the pin.

The invention is directed to an improved internal combustion engine, having a symmetric cylindrical arrangement and using a bevel gear train to join multiple crankshaft sections. It provides for a naturally smoother operation with less vibration than in-line engines. Better efficiency is expected with the engine than with comparable in-line engines. Manufacturing is expected to be simpler and gasket-sealing better than the in-line and V types of engines. Compactness will add to the engine's util...

A cylindrical battery including a wound electrode assembly and a center pin disposed in a center space of the electrode assembly, the center pin having a gap along its length, the gap defined by opposing edges of the center pin, wherein at least one of the opposing edges is sloped.

In a cylindrical sieve, a first frame 7 is provided with a first ring plate 7a arranged in a radial direction and a ring plate 7b extended inward in an axial direction X of the sieve from an inner end of the first ring plate 7a. The ring plate 7b has an inwardly warped end. A ring projection 2a is fit in a ring-shaped cavity K1 defined by a ring recess 10a and the first frame 7. The ring plate 7b presses the ring projection 2a outward in the radial direction to prevent the ring projection 2a fro...

The present invention provides a cylindrical battery excellent in impact resistance. A novel cylindrical battery is provided comprising a cylindrical battery main body received in a closed-end cylindrical metallic container, characterized in that the cylindrical battery main body comprises a spirally-wound plate group having two output terminals on the same edge face, a closed-end cylindrical battery jar made of a resin for receiving the spirally-wound plate group and a resin cover for closing t...

In a cylindrical screen, a screen body has a height greater than its diameter, and is formed of a plurality of portions spaced apart from each other in a direction of the height. Each portion has slits laterally and vertically spaced apart from each other. At least one annular member is situated between two of the plurality of the portions of the screen body to be located radially inside an outer surface of the screen. The annular member has an annular concave formed in a middle thereof extendin...

The disclosed method can manufacture a thick-walled cylindrical part of an excellent quality which is free from the interlayer separation, by using a fiber reinforced plastic composite material. The fiber reinforced plastic composite material having a small thermal expansion coefficient is laminated in the circumferential direction of a mandrel; the laminated fiber reinforced plastic composite material layer is heat-cured to form an auxiliary member of the mandrel; a plurality of sorts of fiber ...

Actuator, especially suited for an actuating mechanism for parabolic and other reflector dishes. The actuator comprises two co-axial cylinders (8, 12). A helical guideway (10) is provided on the outer surface of the inner cylinder (12) or the inner surface of the outer cylinder (8), and a plurality of guide means are provided on the other of the outer surface of the inner cylinder (12) or the inner surface of the outer cylinder (8) to run in or along the helical guideway (10). The actuator is el...

A monopulse antenna system comprising an inner antenna and an outer antenna disposed symmetrically about a central axis of symmetry. A central aperture is located at the axis of symmetry through which a weapon system may fire or an additional sensor may be located. The inner antenna is preferably annular in shape and produces a relatively broad antenna pattern. The outer antenna is also preferably annular and produces a beam pattern with many lobes. The received signals A and B, from each beam p...
