A process for room temperature substrate bonding employs a first substrate substantially transparent to a laser wavelength is selected. A second substrate for mating at an interface with the first substrate is then selected. A transmissivity change at the interface is created and the first and second substrates are mated at the interface. The first substrate is then irradiated with a laser of the transparency wavelength substantially focused at the interface and a localized high temperature at the interface from energy supplied by the laser is created. The first and second substrates immediately adjacent the interface are softened with diffusion across the interface to fuse the substrates.

A stretch-blown plastic container, includes a container body which encloses a filling volume with a container bottom; a container neck which adjoins an opposite end of the container body, having a container opening and an integrated handle region, the handle region being hollow and joined to the filling volume which is enclosed by the container body; and between the handle region and the container body, a through opening recessed and bordered over its entire periphery by wall parts of the container body and of the handle region which have been welded to one another.

Provided is a method of manufacturing a heterogeneous material joined body, the method comprising irradiating a surface of a glass layer with a first laser to form two or more etched lines on the surface of the glass layer; providing a resin layer on the surface of the glass layer having the two or more etched lines; and irradiating the surface of the glass layer with the resin layer with a second laser to fill the etched lines and the surface of the glass layer with the resin layer and join the resin layer and the glass layer, wherein the glass layer having the two or more etched lines is irradiated with the second laser in a direction from the glass layer to the resin layer with focus on the surface of the glass layer which is in contact with the resin layer.

A first plastic part is fixtured in a first fixture, and a second plastic part is fixtured in a second fixture for welding to each other. The first plastic part can be independently moved relative to the second plastic part in each of three directions: 1) linearly in a direction parallel with a z-axis, 2) linearly in a direction parallel with an x-axis, and 3) circularly in a circular arc about an axis parallel with a y-axis.

Disclosed herein are sealed devices comprising a first substrate, a second substrate, an inorganic film between the first and second substrates, and at least one bond between the first and second substrates. The inorganic film can comprise about 10-80 mol % B.sub.2O.sub.3, about 5-60 mol % Bi.sub.2O.sub.3, and about 0-70 mol % ZnO. Methods for sealing devices using such an inorganic film are also disclosed herein, as well as display and electronic components comprising such sealed devices.

A seam production machine for joining at least two planar flexible components is provided, wherein at least one of the components includes thermoplastic synthetic material. Included is a machine housing, which is designed with a work surface and a work arm, wherein a retaining bar mounted movably in the longitudinal axis including a seam production tool and a likewise mounted support bar including a component presser element are provided on the work arm, and a support plate for the components, including at least one oscillatingly drivable component feeder is disposed in the work surface, wherein the component presser element is lowerable and acted upon by a force and, when lowered, cooperates with the at least one component feeder. At least one seam pressing ram, serving as the seam production tool, is disposed at the bottom of the retaining bar, wherein a laser beam is directed at the support plate and forms a laser light spot there for plasticizing the synthetic material of at least one of the components.

The invention relates to a method for manufacturing a plastic pedelec frame (1) by, preferably integrally, joining two matching plastic half-shells (2, 3), said pedelec frame being provided with receptacles (12, 13, 14) for a handlebar (4), a bottom bracket (5) and preferably a seat (6). The two plastic half shells (2, 3) are made from a fiber-reinforced thermoplastic material containing a partially aromatic polyamide, using an injection molding process. The invention also relates to a pedelec frame (1) manufactured by said method.

Transparent glass-to-glass hermetic seals are formed by providing a low melting temperature sealing glass along a sealing interface between two glass substrates and irradiating the interface with laser radiation. Absorption by the sealing glass and induced transient absorption by the glass substrates along the sealing interface causes localized heating and melting of both the sealing glass layer and the substrate materials, which results in the formation of a glass-to-glass weld. Due to the transient absorption by the substrate material, the sealed region is transparent upon cooling.

There is provided a synthetic resin welded body and a method of manufacturing the same, in which it is possible to make only a portion of an absorption-side synthetic resin part to be welded likely to melt in laser welding. The synthetic resin welded body includes: a laser light absorbing oil passage forming member (absorption-side synthetic resin part); and a laser light transmissive baffle plate (transmission-side synthetic resin part) which is laid over the oil passage forming member and laser-welded in this state. The baffle plate is formed so that a welded area which is laser-welded to the oil passage forming member is higher in laser transmittance than a non-welded area which is the other area.
