A method for producing a part. This part including a surface portion whereon is positioned an element to be assembled via an adhesive on the surface portion. The method includes the steps of: mounting a sleeve of heat-shrinkable material around at least one portion of the element on the part, heating of the sleeve in order to shrink it and thus to apply an application force of the element on the surface portion, hardening of the adhesive, and removing the sleeve.

A first component (16) for a personal care device comprises a first coupling interface for allowing the first component (16) to be releasably and repeatably coupled to a second component for the personal care device via a second coupling interface of the second component. The first coupling interface comprising a portion of material (38) that can change shape with changes in temperature to couple the first coupling interface to the second coupling interface. The portion of the material (38; 60) is configured to deform during coupling and uncoupling, and to revert towards an original shape after the first coupling interface and the second coupling interface have been coupled or uncoupled. The invention also provides a personal care device (10) comprising the first component (16; 12), and the second component (12; 16) having the second coupling interface.

A method of assembling mating components includes the steps of heating an inner surface of a first cavity of a first part to generate a first expansion, heating an outer surface of a component surrounding an outer periphery of the first part to generate a second expansion of the component that corresponds to the first expansion of the first part, inserting a second part into the first cavity while the first part is in an expanded condition, and cooling the first part to contract around the second part.

A shrink-tubing measurement guide has a flexible strip with a measuring surface and a measurement indicator. Bands on the measuring surface form a tubing size indicator gauge, with each band having a band-specific indicium different from any adjacent band and associating a specific size of shrink tubing. The tubing size indicator gauge has a measuring surface layout based on a circumferential difference between a hand tool body and a hand tool end being compared to a predefined value, where the bands are either aligned end to end along the measuring surface or progressively-staggered with at least one end of each band extending beyond an adjacent band. The flexible strip is configured to be wrapped around a hand tool body of the hand tool with the measurement indicator aligning with at least one of the plurality of bands, where each band-specific indicium identifies a specific shrink tubing size.

A heat treatment method is provided in which a first steel component (11) formed with a coating (111) thereon is fitted in first holes (123, 124) of a second steel component (12) subjected to a quenching treatment. The heat treatment method includes a heating step of heating the second steel component to a first temperature (T.sub.1) equal to or higher than a tempering temperature (T.sub.0) of the second steel component and higher than a temperature of the first steel component by a temperature difference (T) for achieving shrink fitting and a shrink-fitting step of shrink-fitting the first steel component in the first holes of the second steel component in a state of maintaining the temperature difference for achieving shrink fitting between the first steel component and the second steel component.

The present invention provides paper glasses and a method for manufacturing the same including a lens frame connected in parallel to both sides of a central bridge to fix a lens; glasses temples which are extended integrally from both sides of the lens frame and bent at an angle perpendicular to the lens frame to wear the lens frame on the face; and a support piece of which one end is fixed to the lens frame and the other end is fixed to the front end of the glasses temples to ensure a support force of the glasses temples and maintain a predetermined angle of the glasses temples.

A mechanical connection between a ring gear made of plastic, and a housing part, the mechanical connection includes a heat-shrunk tubing made of plastic, the heat-shrunk tubing positioned in a connecting region between the ring gear and the housing part to create a positive-locking and/or frictional connection between the ring gear and the housing part.

A joining method of joining two pieces of subjects to be joined together, the subjects being a first member and a second member that has a joint insertion portion in which the first member is inserted, the method including: heating the second member that is set in an expansion restricting member and in which the first member is inserted to the joint insertion portion to first temperature to cause the second member to have thermal expansion and thereby causing the joint insertion portion to have plastic deformation in a direction in which a diameter shrinks with mechanically restricting thermal expansion of the second member by an inner surface of the expansion restricting member; and cooling the second member after the heating to join the first member and the second member together.

A hollow vane, includes a main portion, of which the cavity is closed by a cover, that is produced by expanding the main portion relative to the cover, for example by means of differential thermal expansion, then by placing the cover at the bottom of the opening of the cavity, before allowing the main portion to close again, closing a nesting between a protrusion at the bottom of the cover and a widening at the bottom of the opening. The disadvantages linked to the use of welding, glue or even assembly parts are as such avoided.

A vehicle includes a prime mover including at least two fluid conduits, and a heat shrink sleeve provided around the at least two fluid conduits. The heat shrink tube forms a conduit bundle of the at least two fluid conduits.
