A wafer-processing apparatus includes: eight or ten reactors with identical capacity for processing wafers on the same plane, constituting four or five discrete units, each unit having two reactors arranged side by side with their fronts aligned in a line; a wafer-handling chamber including two wafer-handling robot arms each having at least two end-effectors; a load lock chamber; and a sequencer for performing, using the two wafer-handling robot arms, steps of unloading / loading processed / unprocessed wafers from / to any one of the units, and steps of unloading / loading processed / unprocessed wafers from / to all the other respective units in sequence while the wafers are in the one of the units.

A device for fabricating a composite article having a plurality of material dispensers to increase productivity. The device includes a structure defining a work surface datum, the plurality of material dispensers which are movable relative to the structure, where each of the material dispensers applies a strip material to the work surface datum along a predetermined axis, and wherein each of said predetermined axes are parallel to one another and where the strip material as applied to the work surface datum forms a layer. A method for fabricating a composite in accordance with the present invention is also provided.

An apparatus and method for separating a semiconductor die (303) from an adhesive tape (32) are disclosed. The apparatus includes a blade (34) mechanically coupled to a blade holder (36), wherein the blade (34) is inclined relative to the primary surface of the semiconductor die (303). The method further comprises lifting the semiconductor die (303) while it is attached to the adhesive tape (32) to assist disengagement. The blade (34) facilitates peeling of the semiconductor die (303) from the adhesive tape (32) while distributing stress exerted on the semiconductor die (303) over a larger surface area resulting in reduced die fractures (20).

A replaceable tow alignment path kit for a tow placement device may include a tow alignment tray to guide a predetermined width of tow along a tow path of a tow placement head. The tow alignment tray may include a channel having a width corresponding to the predetermined width of tow and a connector to releasably engage the tow placement head.

A shuffling hand feeling and unwanted non-uniform absorption characteristics in the case of using a tow (fiber bundle) are prevented.An absorbent body includes a fiber aggregate 21 formed by opening the tow, a super absorbent polymer 54, and a sheet covering these components; and includesthe super absorbent polymer 54 bonded to the sheet 58 with an adhesive that is applied in a continuous plane to the entire surface or the substantially entire surface of at least the portion to be provided with the super absorbent polymer 54 in this sheet 58.

Systems and methods for applying a web material to substrates are disclosed. In one example, there is provided a single first drive that may be coupled to a feed mechanism, a vacuum roll, and a rotary knife such that the respective peripheral speed of the feed mechanism, the vacuum roll, and the rotary knife is adjustable to provide a cut web material length that is in registry with a predetermined location on the substrate. In another example, there is disclosed a method that involves detecting a substrate to which a length of web material can be applied, and initiating introduction of a web material into a feed mechanism only if the substrate is detected. Another example includes introducing a web material traveling at a predetermined speed onto a vacuum roll that is positioned near a rotary knife, and rotating the rotary knife at a peripheral speed that is substantially the same as the predetermined speed of the web material traveling on the vacuum roll.

An apparatus for applying a cutting edge tape or a reinforcing tape to a substrate by feeding and cutting lengths of tape and advancing the lengths to a vacuum wheel applicator, the feed section of the apparatus comprising a feed roll, an anvil vacuum roll, and a rotary knife adjacent to the anvil vacuum roll, and means for adjusting the speed of the feed roll and the speed of the anvil vacuum roll to vary the length of the tape advanced to the applicator.

The present welding device is a device for welding webs W, the device including: a drum 20 and an anvil 21 rotating about an axis; a transfer section 22 provided on a periphery of the drum 20 to rotate together with the drum 20; a horn 11 which, together with the anvil 21, applies a vibration energy to a layered portion of the webs; a cutter 30 which comes into contact with the anvil 21 to cut the webs; a sensor 40 for measuring a distance between the anvil 21 and the horn 11; and a control section for controlling a relative positions of the anvil 21 and the horn 11 based on the measured distance between the anvil 21 and the horn 11 as measured by the sensor. While the horn 11, together with the anvil 21, applies the violation energy to the webs W, the cutting of the webs W by the cutter 30 is not performed.

A button assembly for a home appliance is provided which allows for effective illumination of buttons. The button assembly includes a button body having buttons thereon which may pressed by a user to operate the appliance. The button body has a predetermined space inside, an elastic member which elastically supports the button body, a luminous body provided within the button body to emit light, and an extension extending from the button body which activates a corresponding switch, the extension being configured not to interfere with the luminous body.
