An interior rearview mirror assembly for vehicles incorporates a reflective mirror element and a first polymeric pivot joint allowing pivotal adjustment of the field of view of the reflective element. The assembly includes a polymeric support element, a polymeric rearview mirror mount, and a second polymeric pivot joint. The polymeric support element includes one of a first polymeric ball member and a first polymeric socket. The polymeric rearview mirror mount is adapted for attachment to an interior portion of the vehicle. The support element pivots on the second polymeric pivot joint about the rearview mirror mount. At least one of the pivot joints includes joint members generating increased frictional resistance to movement of a ball member in a socket, such joint members preferably comprising a textured surface on the ball member or socket.

The invention relates to a pre-installation assembly (10) for a contact arrangement of a sensor assembly, comprising a support component (20), a clamping component (23) and at least one spring contact pin (11), wherein conductive end areas of the at least one spring contact pin (11) that are connected with one another are designed to be axially incompressible and held under an axial spring load between support surfaces that are at a distance from one another. According to the invention, the support component (20) and the clamping component (23) are connected with one another by way of connection means, wherein the at least one spring contact pin (11) is positioned and held by way of aligned guides (21, 22) in the support component (20) and in the clamping component (23), said spring contact pin passing through said guides, wherein a first end section (11b) of the at least one spring contact pin (11) is axially supported in the associated guide (21) of the support component (20), and wherein a second end section (11b) of the at least one spring contact pin (11) is axially supported in the associated guide (22) of the clamping component (23).

A turbine blade assembly, in particular for a gas turbine, is provided. The turbine blade assembly includes a disc with a rotation axis, turbine blades, each turbine blade including an airfoil, a blade root and a platform between the airfoil and the blade root by which it may be fixed to the disc, locking plates and bent seal strips. The turbine blades are arranged adjacent to each other on the disc, such that gaps are present between the platforms of adjacent turbine blades and root cavities are present between the portions of the roots of adjacent turbine blades. The turbine blades are secured axially to the disc by the locking plates. The seal strips are arranged in the gaps between the platforms of neighboring turbine blades to seal the gap and protrude axially over the blade root and over the locking plate.

A method of manufacturing a casing of an electronic product with surface decoration thereon has a step of designing a decorative image, a step of printing a decorative layer on a film, and a step of injection molding. The decorative image is designed by using a computer. The decorative image is transformed into a decorative layer and the decorative layer is printed on a film by using a computer and a printer connected with each other. The casing of an electronic product with surface decoration thereof is obtained by applying in-mold decoration and injection molding technology, which combines injection material with the film.

According to the present invention, it is possible to provide a method for producing a 1,3-dimethyladamantane represented by formula (2) by performing a skeletal isomerization reaction using, as the catalyst, 0.5 to 1.5 parts by weight of HF and 0.05 to 0.5 parts by weight of BF3 relative to 1 part by weight of perhydroacenaphthene represented by formula (1) under reaction temperatures between 60 and 110 DEG C.

The present invention relates to an optical glass having a refractive index (nd) of greater than or equal to 1.65 and an Abbé number (ν (nu)d) of greater than or equal to 50 for use in precision press molding. The glass exhibits that a ratio α (alpha)1 / α (alpha)2 is less than 17 when temperature denoting maximum value of differential in amount of elongation of glass relative to temperature differential DELTAT (where DELTAT denotes a constant value of 1° C. or less) over a temperature range from glass transition temperature (Tg) to sag temperature (Ts) is denoted as T1, average coefficient of linear expansion over a range from T1−5° C. to T1+5° C. is denoted as alpha1, and average coefficient of linear expansion over a range from the glass transition temperature (Tg)−160° C. to the glass transition temperature (Tg)−140° C. is denoted as alpha2.

A fiber loop formed by bending of a connection section between the first fiber and the second fiber includes a coupling region and an upper taper region as well as a down taper region arranged symmetrically on two sides of the coupling region. Then the fiber optic splitter with the fiber loop is assembled with a splitting ratio modulation mechanism. Thus the manufacturing of the fiber optic power splitter with variable splitting ratio is simplified and this favors production and applications of the device. Moreover, the splitting and modulation quality of the splitter are stable and are controlled precisely. Thus the economic benefits of the device in manufacturing, operation quality and product competitiveness are all improved.

A process for manufacturing a glass substrate for a magnetic recording medium, comprising polishing a glass substrate is polished using abrasive grains and then washing the substrate using a 0.02-0.3% aqueous hydrofluoric acid solution, and a glass substrate for a magnetic recording medium which is manufactured by the process. A polished glass substrate for a magnetic recording medium is manufactured, whereby during washing after polishing of the glass substrate, manifestation of substrate surface defects and overall waviness of the substrate can be minimized, and whereby texture formation in the subsequent texturing step can be accomplished in uniform manner without creating variation between substrates.
