Wire-stranded medical hollow tube, and a medical guide wire

In a wire-stranded hollow tube (1), a plurality of metallic wires (8) preformed with a predetermined forming rate are twisted along a circular line into a careless hollow configuration. When twisting the metallic wires (8), the neighboring metallic elements (1a, 1a) are subjected to compression with no gap between the neighboring metallic elements (1a, 1a). This increases a contact pressure between the neighboring metallic elements (1a, 1a) to attain a good tightness with a good circularity and diametrical uniformity secured therebetween, thus preventing the wire-stranded hollow tube (1) from inadvertently collapsing. A tightness is strengthened between the neighboring metallic elements (1a, 1a) when the metallic elements (1a, 1a) of different helical pitch are used. By applying the wire-stranded hollow tube (1) to a medical guide wire, a quick torque response and a good torque transmissibility are ensured which lead to a good manipulatability with a favorable follow-on capability.

Fastening arrangement for a split casing

InactiveUS7198465B1Increase contact pressureIncrease effective wall thicknessWashersPump componentsGas turbinesEngineering
A casing of a hydraulic machine such as a gas turbine is formed as a horizontally split type flangeless casing. The flangeless casing consists of an upper casing and a lower casing joined together at joint faces and fastened by fastening bolts. The fastening bolt has a screw thread which engages the threaded hole on the joint face of the lower casing. A bolt hole having an internal screw thread and through which the fastening bolt passes is provided in the upper casing. A sleeve having an external screw thread is fitted into the bolt hole of the upper casing by engaging the external screw of the sleeve with the internal sleeve of the bolt hole. An enlarged diameter portion is formed on a shaft of the fastening bolt at the portion where the enlarged diameter portion abuts an upper end face of the sleeve when the fastening bolt is screwed into the threaded hole in the lower casing. When the fastening bolt is tightened, the shaft tensile force of the bolt is received by the abutment of the enlarged diameter portion and the upper end face of the sleeve and, then, transferred from the sleeve to the upper casing through the engagement of the external screw thread of the sleeve and the internal screw thread of the bolt hole of the upper casing and generates the fastening force which presses the upper casing to the lower casing.

Non-involute gears with conformal contact

InactiveUS6837123B2Eliminate high contact pressure peakEasy to adaptPortable liftingGearing elementsInvolute gearTorque transmission
Several embodiments of various non-involute gear tooth profiles incorporate relief areas formed across the area of the tooth face generally symmetrically to each side of the pitch circle of the gear. The relief area serves to preclude contact across the areas of meshing or mating gear teeth where convex-to-convex contact would otherwise occur, thus precluding high pressure contact between the two gear teeth at the area of the relief. The remainder of the contact of such non-involute gear tooth profiles provides conformal contact, i. e., convex-to-concave mating faces with correspondingly low pressures developed between the tooth portions. The present invention enables a given gear set to absorb considerably greater torque and force than would otherwise be they case, or alternatively allows gear sets to be made considerably smaller and lighter for a given torque transmission, than would otherwise be the case.

Flat cable electrical connector

ActiveUS20070032115A1Satisfactory click sensationHigh contact pressureEngagement/disengagement of coupling partsCoupling contact membersCamEngineering
When the movable member (30) is at the open position, the cam portion (33) of the movable member (30) is out of contact with the pressure receiving portion of a lever arm (21), making it possible to insert a flat cable into the connector on the contact side. When the movable member (30) is at the closed position, the cam portion (33) comes into contact with the pressure receiving portion that consists of a shoulder (21D) and a concave indentation (21B). While the movable member (30) is moving to the closed position, the cam portion (33) pushes the shoulder (21D) to provide the pressure receiving portion with the highest pressure. When the movable member (30) reaches the closed position, the cam portion (33) rests in the concave indentation (21B) while maintaining a pressure less than the highest pressure.

Axial elastic force-applying connection method for electric connector contact pair

The invention provides a method for the axial elastic force application connection of electrical connector contact pairs. The method adopts an elastic element to apply axial external force to a contact pair consisting of a contact piece A (1) and a contact piece B (2), so as to combine the two tightly, thereby forming the electric connection with lower conductive resistance. One end of the elastic element is in contact with an insulating base so as to turn into a relative fixed end; and the other end of the elastic element directly acts on a preset fixed end face of an electric conductor contact piece, and is a relative displacement end during axial force application. The contact pair is independently formed by the end planes of the two contact pieces with simple structure. As axial elastic connection can not be affected by shock or other external factors, the connection reliability is higher. The contact pair can be formed by a positive contact piece and a negative contact piece as well, which ensures that the radial and axial directions of the contact pair are uniform in stress and contact.
