True zero-clearance cutting on a commercial scale is provided via a cutting area including a sacrifice material that is relatively softer than the cutter. One example is a cutting system which is capable of cutting a material such as, for example, tape or paper, into a fiber or powder. The cutting system includes a cutting blade, typically a rotary cutter, and a sacrificial plate or round bar contacting the cutting blade. The contacting portion has a zero clearance during the cutting operation. ...

A seatbelt pretensioner mechanism (10) for use with a seatbelt retractor (11). The retractor (11) has a spool (16) configured for winding a seatbelt webbing thereon. The pretensioner mechanism (10) is housed inside the retractor spool (16). The pretensioner mechanism (10) includes a movable actuator member (22) slidably coupled to the retractor spool (16), and a stationary member (20) secured to the retractor (11) along a path of slidable movement of the movable member (22). Helical splines (23)...

In a helical antenna having an antenna pattern of a helical shape, the antenna pattern extends along a cylindrical body formed by an insulating film member which is rolled into a cylindrical shape. A circuit board is placed opposite to one of axial ends of the cylindrical body. The circuit board is formed with a circuit pattern connected to the antenna pattern by soldering. The cylindrical body has a specific part which is not provided with the antenna pattern and is fixed to the circuit board.

A small and light helical antenna, with a high gain, includes arranging the dielectric cylinder with a helix conductor on the conductive plate and arranging a thin rectangular conductive plate between the lower end of the helix conductor and the feed point in a predetermined position of the conductive plate. The impedance matching is between the input impedance of the helix conductor and a power feeder. The upper and lower conductive plates constitute parallel plate waveguide space, and the prob...

Helical peptidomimetic compounds as inhibitors of beta-amyloid production are provided. These inhibitors preferably inhibit intramembrane proteases, notably aspartyl secretases involved in the enzymatic cleavage of amyloid precursor protein (APP) to yield amyloid-.beta. peptide. Methods are provided for making a medicament containing the compounds and for administering the compounds to treat .beta.-amyloid-associated diseases, notably Alzheimer's disease.

A new design for helical gearsets is disclosed in which the new gearsets meet all applicable ratings and standards of the American Gear Manufacturers Association (AGMA), and yet allows very substantial cost savings over prior similar gearsets having an equivalent AGMA rating. The gearsets of the instant invention generally are substantially thinner, and have fewer, but larger, gear teeth than the prior gearsets they replace. A helical gearset of the present invention includes a pinion and a gear...

A method of providing a shed (2) for a high-voltage insulator (1) includes providing a substantially tubular substrate (3), providing an extruder (10) having an extruder head (11) defining an extrusion direction (A), using the extruder (10) to extrude the shed (2) and applying the shed (2) on the substrate (3) while rotating the substrate relative to the extruder head (11). The extrusion direction (A) substantially coincides with the longitudinal axis of the substrate (3), and the substrate (3) ...

A helical antenna has a helix supported by a helix support. The helix support includes at least one piece of flexible sheet having its two surfaces covered with a layer antistatic material. The flexible sheet is curlable into a revolution surface configuration to form a revolution surface-shaped support section for at least partially supporting a portion of the helix component there around. A grounding mechanism electrically grounds the external sheet surface to the helix and the two sheet surfa...

The present invention relates to a therapeutic probe adapted to aid in the insertion and navigation of the probe into delicate tissue structures, and to provide protection of adjacent tissue structures.

In a helical antenna operable at a plurality of frequencies, a radiation element includes a first pitch portion which is connected to a feeding point and in which the electric conductor is wound around or folded back at a first pitch, and a second pitch portion which is connected to the first pitch portion and in which the electric conductor is wound around or folded back at a second pitch different from the first pitch. A tip end stab element extended from the tip end of the radiation element i...
