  • Patent number: 9805980
    Abstract: A semiconductor device manufacturing method comprising the steps of providing a matrix substrate having a main surface with plural device areas formed thereon, fixing plural semiconductor chips to the plural device areas respectively, then sealing the plural semiconductor chips all together with resin to form a block sealing member, dividing the block sealing member and the matrix substrate for each of the device areas by dicing, thereafter rubbing a surface of each of the diced sealing member portions with a brush, then storing semiconductor devices formed by the dicing once into pockets respectively of a tray, and conveying the semiconductor devices each individually from the tray. Since the substrate dividing work after block molding is performed by dicing while vacuum-chucking the surface of the block sealing member, the substrate division can be done without imposing any stress on an external terminal mounting surface of the matrix substrate.

The other circular saw blade may be positioned entirely above the top surface of the conveyor system. The thin veneer stone saw may be operable to produce thin veneer stones in a variety of widths. The thin veneer stones may be used to form facade for a structure.

  • Publication number: 20110232621
    Abstract: The present invention provides a portable stone shaper resembling a tabletop jigsaw, this machine contains operational components germane to larger stone and tile cutters. Yet, in addition to its compact size, the Portable Stone Cutter embodies other unique design features. First, the base of the unit contains a two inch water tank and pump mechanism. This component facilitates proper lubrication, as well as safe and pristine finishes. Additionally, the device of the present invention is able to use virtually any type of common or specialized bits for cutting. Easily interchangeable, the versatility of the bit usage ensures that one has any bit needed for any job at all times. The Portable Stone Cutter can be sold with a standard bit selection and other bit designs made especially for this product are sold separately, as an aftermarket product. The device of the present invention operates on conventional one hundred ten volts, sixty hertz power and is connected to a standard power outlet.

  • Patent number: 7987752
    Abstract: Certain embodiments of the present technology provide systems and methods for delivering pressurized fluid to a rotary cutting blade. For example, in certain embodiments, a system for delivering pressurized fluid to a rotary cutting blade includes: a pump configured to receive fluid from a fluid source and pressurize the fluid; and a nozzle configured to receive pressurized fluid from the pump and deliver the pressurized fluid to a rotary cutting blade as an atomized fluid stream, wherein the pump pressurizes the fluid to a pressure sufficient to cause the fluid to be atomized when the fluid is passed through the nozzle. For example, in certain embodiments, a method for delivering pressurized fluid to a rotary cutting blade includes: delivering fluid to a pump; pressurizing the fluid using the pump; and delivering the pressurized fluid to a rotary cutting blade through a nozzle as an atomized fluid stream.

  • Patent number: 7841069
    Abstract: A method of manufacturing thin closure magnetic read/write heads, such as magnetic tape heads is provided. The method provides improved flexural strength of the closure so that the closure breakage during fabrication of the heads is mitigated and closure thickness is reduced. An array of chips is fabricated on a wafer. The array is closed, with a closure strip bonded to each row of the array. Closures span only the length of a row, so that the closures are not subjected to flexure during processing and breakage due to flexure is mitigated. Side bars are bonded to the array to form a column with dimensions similar to prior art columns. This allows columns manufactured by the invention to undergo additional processing using existing processes.

  • Patent number: 7819112
    Abstract: A stone cutting device that utilizes first and second blade assemblies aligned within first and second support members. The first blade assembly is equipped with a source of hydraulic pressure that provides force to drive a blade downward. A second blade assembly meanwhile has a blade disposed within an opening of a table such that when a stone is placed on the table the blade does not contact the stone. Resilient members are placed underneath the table such that when pressure is applied from the blade of the first blade assembly the table and stone move downwardly to contact the blade of the second blade assembly thus providing pressure on either side of the stone in order to cut the stone or block.
