摘要:
An infrared apparatus includes a case, and an infrared device to input and/or output infrared rays. In the infrared apparatus in which the infrared device is received in the case, the case has an infrared transmitting window part which transmits only infrared light and which does not transmit visible light. Of a light transmitting resin through which near-infrared laser used for near-infrared laser welding passes and a light absorbing resin which emits heat and melts when receiving the near-infrared laser, the infrared transmitting window part is made of the light transmitting resin.

In a system for laser welding work pieces along a collapsing weld interface, methods and apparatus include providing welding pads and/or stop projections on either or both of the work pieces to control the manner or amount of collapse. Preferably, the stop projections exist a separation distance from the weld interface while the welding pads exist at and form a portion of the weld interface. Buffers are taught between the weld interface and stop projection. The work pieces may comprise inkjet printhead lids and bodies. In another aspect, the invention teaches methods of laser welding inkjet printhead lids and bodies according to whether the inkjet printhead body embodies a mono or color ink body type and especially includes selective control of one or more laser light sources to illuminate the inkjet printhead lid in a specific pattern of light.

A method and means of detecting the seals of a package is disclosed herein. The invention includes coloring the inner coating of a laminated material that is used to create a package on a form, fill and seal packaging machine. The invention also discloses coloring the longitudinal strip of the package. The coloring of the inner coating allows an operator to distinguish between an acceptable seal and a defective seal since a delamination, which is acceptable, may appear to be a defective seal without the inner coating coloring. The colored longitudinal strip also allows one to distinguish between a defective longitudinal seal and a delamination of the longitudinal strip.

A laser weldable composition comprising a polyester component, 5 to 50 weight percent of a filler; and 10 to 30 wt. % of a poly(ester-carbonate) copolymer comprising carbonate units and ester units of the formula (I) wherein: T is a C2-20 alkylene, a C6-20 cycloalkylene, or a C6-20 arylene; R1 and J are each independently (a) a bisphenol A divalent group, and (b) a C16 or higher divalent group (b1), (b2), or (b1) and (b2), wherein (b1) is a phthalimidine divalent group, and (b2) is a third divalent group, wherein the C16 or higher divalent group (b1), (b2) or a combination of (b1) and (b2) is present in an amount of 40 mol % to 50 mol % based on the total moles of the bisphenol A divalent groups and the C16 or higher divalent group; and the composition, when molded into an article having a 2.0 mm thickness, provides a near infrared transmission at 960 nanometers of greater than 50% and a thermal resistance according to HDT 1.8 MPa flat (ISO 75/Af) is greater than 160° C.
摘要:
A thermoplastic polyurethane is foamed by way of an added vesicant and is then extruded to provide a thermoplastic forming material. The thermoplastic forming material is roll pressed to provide an unfinished sheet, and a surface of the unfinished sheet is embossed for printing a predetermined drawing to provide an embossed sheet. The embossed sheet is cut to provide plural connecting sheets, and the partial overlapping of two adjacent connecting sheets is ultrasonically welded to provide a connected exterior. At least one groove is cut in the predetermined drawing surface of the exterior to provide a ball texture.
