A laser processing method is disclosed which is capable of easily reducing contamination on a plastic film surface, and also capable of cutting a plastic film in a free-form shape. A laser processing method includes a process of pulsing a laser beam L having a wavelength in the infrared region from a laser beam source 1 and causing a plastic film F to be irradiated with the laser beam L to cut the plastic film. The peak energy density of the laser beam with which the plastic film is irradiated is 70 J/cm.sup.2 or more and 270 J/cm.sup.2 or less.

The present invention relates to a sealing member for a base station antenna and a base station antenna comprising the same as well as a method and device for manufacturing the sealing member. The sealing member (2) is flexible and resilient and is configured to form a seal between an open end (5) of a radome (3) and an end cap (1) of the base station antenna. The sealing member is an elongated sealing strip having two ends, wherein the two ends of the sealing member are lappable with each other, and the sealing member has a groove extending over its entire length, which groove is defined by two side limbs and a bottom limb connecting the two side limbs of the sealing member, wherein the groove is configured to engage with an edge of the open end (5) of the radome, and wherein the sealing member is configured to be received in an annular recess of the end cap (1) and isolate an interior of the radome (3) from the environment. The sealing member can be manufactured cheaply and can be flexibly applied to base station antennas with different sizes.

In order to be capable of reliably supplying a prescribed amount of fiber materials into a heating cylinder for each cycle and continuously manufacturing a homogeneous composite material, a plasticizing unit is provided with a fiber supply device 3 that supplies prescribed amount of fiber materials A2 having a prescribed length into the heating cylinder 1. The fiber supply device 3 is provided with: a cutting section 12 that cuts off a long fiber material A1 pulled out from a reel 11 into a prescribed length; a pressure-feeding section 13 that presses the fiber materials A2 having the prescribed length cut off by the cutting section 12 into the heating cylinder 1; and a fiber transfer device 45 that forcibly transfers the fiber materials A2 accumulated in the cutting section 12 to the pressure-feeding section 13. The pressure-feeding section 13 is constituted by a press cylinder 41 and a press piston 42, and the fiber transfer device 45 is constituted by a vacuum device.

A method of manufacturing a flow field plate includes mixing graphite and resin materials to provide a mixture. The mixture is formed into a continuous flow field plate, for example, by ram extrusion or one or more press belts. The continuous flow field plate is separated into discrete flow field plates. Flow field channels are provided in one of the continuous flow field plate and the discrete flow field plates.

The present invention provides a system and method for making a three-dimensional electronic, electromagnetic or electromechanical component/device by: (1) creating one or more layers of a three-dimensional substrate by depositing a substrate material in a layer-by-layer fashion, wherein the substrate includes a plurality of interconnection cavities and component cavities; (2) filling the interconnection cavities with a conductive material; and (3) placing one or more components in the component cavities.

An encapsulation cover for an electronic package includes a cover body having a frontal wall provided with at least one optical element allowing light to pass through. The optical element is inserted into the encapsulation cover by overmolding into a through-passage of the frontal wall. A front face of the optical element is set back with respect to a front face of the frontal wall. The process for fabricating the encapsulation cover includes forming a stack of a sacrificial spacer on top of an optical element, with the stack placed into a cavity of a mold.

A container-labeling apparatus includes a label-strip feeder having a vacuum drum and a vacuum cylinder that has vacuum regions extending between different angular ranges. A first vacuum source provides the vacuum at the vacuum drum and a second vacuum source provides the vacuum at the vacuum cylinder. During operation, the vacuum regions provide different under-pressures.
