The invention provides a method for manufacturing a friction damped disc brake rotor, including the steps of: (A) positioning at least one insert into a mold, wherein the insert has a body with tabs extending therefrom to hold the insert in a desired position within the mold; and (B) casting a rotor cheek of the disc brake rotor in the mold around the insert such that a portion of each tab is bonded with the rotor cheek and the body is substantially non-bonded with the rotor cheek so that the body provides a proper interfacial boundary with the cheek for damping while the bonding of the tabs with the rotor cheek prevents corrosion-causing exterior elements from reaching the interfacial boundary.

The present invention provides a washing apparatus and control method thereof, by which laundry can be dry-cleaned through the loaded configurations of the wet pad cloth, the filth transfer cloth, the steam providing unit, the fragrance spraying unit, and the detergent supplying unit using either the wet pad cloth or the filth transfer cloth or without using both of the wet pad cloth and the filth transfer cloth.

An image sensor package mainly includes a substrate cover having a chip cavity, an image sensor chip, a flexible circuit, and a transparent carrier. The flexible circuit is attached to the transparent carrier. The image sensor chip is flip-chip mounted on the flexible circuit, and then the substrate cover is mounted on the flexible circuit. The flexible circuit has a plurality of first leads electrically connected to bumps of the image sensor chip, and a plurality of second leads to inner terminals of the substrate cover, so that the electrical connection is established between the image sensor chip and the substrate cover through the flexible circuit. A plurality of outer terminals are formed on the opposing surface of the substrate cover corresponding to the inner terminals. Accordingly, the image sensor package provides the excellent electrical transmission and the protection of the image sensor chip. Preferably, a liquid sealant, NCP, or ACP is disposed between the substrate cover and the flexible circuit for hermetically sealing the image sensor chip in the chip cavity. In another embodiment, a glass substrate can replace the assembly of the flexible circuit and the transparent carrier.

Systems, devices and methods for draining and analyzing bodily fluids are disclosed in which a drainage assembly is configured to prevent negative pressure build-up. The drainage assembly generally includes a catheter which may include a drainage lumen, a reservoir, a venting mechanism in fluid communication with the drainage lumen and a positive pressure lumen, and a controller. The venting mechanism may further include a valve which is configured to maintain a closed position, as well as a vent in fluid communication with the valve, where the venting mechanism is configured to inhibit wetting of the vent from fluid within the drainage lumen

A flow rate sensor includes a first body and a second body airtightly and detachably abutting each other. The first body and the second body respectively-include a passage defined therein. The two passages are tapered relative to each other. The first body and the second body respectively have a path defined therein. The two paths respectively communicate with a corresponding one of the two passages in the first and second bodies. A sensing device is airtightly sandwiched between the first and second body and corresponds to the two paths for calculating the different of the fluid that flows through the two passages in the first and second bodies.

An apparatus for curtain coating, particularly for high-speed curtain coating of a continuous paper web substrate (12) is provided with a hopper means (14) providing one or more liquid coating materials in the form of a free-falling curtain (16) impinging the substrate (12) at a dynamic wetting line. Edge guide elements (22, 24) are arranged on both sides supplying a wetting or auxiliary liquid. Each guide element (22, 24) has at least one contact area of its surface directed towards said curtain, which contact area has a multiplicity of grooves (32) and ribs (34) extending along the length of said edge guide elements (22, 24).

A digital lithographic process first deposits a mask layer comprised of print patterned mask features. The print patterned mask features define gaps into which a target material may be deposited, preferably through a digital lithographic process. The target material is cured or hardened, if necessary, into target features. The mask layer is then selectively removed. The remaining target features may then be used as exposure or etch masks, physical structures such as fluid containment elements, etc. Fine feature widths, narrower the minimum width of the print patterned mask features, may be obtained while realizing the benefits of digital lithography in the manufacturing process.
