  • Publication number: 20050208295
    Abstract: The present invention provides an adhesive sheet and a kit for microbial testing, which enable monitoring of the presence of a microorganism and/or the cell count thereof on a solid surface conveniently on a real time basis, and which accommodate to automated focusing during image analysis. The present invention relates to an adhesive sheet for microbial testing having at least a substrate and an adhesive layer, which adhesive layer is compression-bonded to, and peeled from, the surface of a test article to collect microorganisms, and the surface of the adhesive layer is then subjected to image analysis, wherein a marker for focusing the image is provided in the substrate, or in the adhesive layer, or on the surface thereof.

  • Publication number: 20050172904
    Abstract: An electrostatic chuck 108 is provided on a lower electrode 106 provided inside a processing chamber 102 of an etching apparatus 100, and a conductive inner ring body 112a and an insulating outer ring body 112b are encompassing the outer edges of a wafer W mounted on the chuck surface. The temperatures of the wafer W and the inner and outer ring bodies 112a and 112b are detected by first third temperature sensors 142, 144 and 146. A controller 140 controls the pressure levels of He supplied to the space between the center of the wafer W and the electrostatic chuck 108 via first gas outlet ducts 114 and to the space between the outer edges of the wafer W and the electrostatic chuck 108 via second gas outlet ducts 116 and the quantity of heat generated by a heater 148 inside the outer ring body 112b based upon the information on the temperatures thus detected so that the temperatures of the wafer W and the inner ring body 112a are set roughly equal to each other.

  • Publication number: 20050151815
    Abstract: An inkjet printer capable of printing pictorial diagrams and characters clearly without smearing using a solvent ink. A preheater for preliminarily heating the medium forwardly carried toward below the traveling path of the printing head on a rear part of the platen and a print heater for heating the medium that has been carried onto the platen, on which the inkjet droplets ejected from the nozzles of the printing head are landed, are provided. Further, the ink droplets ejected from the nozzles of the printing head and landed on the surface of the medium are prevented from permeating the medium in the surrounding parts of landed points by heating and drying the ink droplets early on the surface part of the medium.

  • Publication number: 20050087853
    Abstract: The present invention relates to a semiconductor device in which an electrode of a device formed on a substrate such as a semiconductor wafer and an electrode of a wiring structure such as an interposer are connected to each other through a connecting electrode extending through the substrate, and a method of manufacturing the same. A semiconductor device according to the present invention comprises a first substrate including a front surface and a back surface, a first device having a first electrode being formed on the front surface; and a wiring structure formed with a second electrode, the wiring structure having a principal surface. The first electrode of the first device and the second electrode of the wiring structure are connected to each other by a connecting electrode extending through the first substrate from the front surface to the back surface thereof. Substantially all the back surface of the first substrate is bonded to the principal surface of the wiring structure.

  • Publication number: 20040251229
    Abstract: By steps of forming first masks 13, 14 each having a first pattern on a first surface of a substrate 11 on which a membrane is to be formed, etching the first surface of the substrate 11 by using the first masks 13, 14 to forming first support beams 15, positioning a second surface of the substrate 11 on the basis of the first pattern on the first surface, forming a second mask 17 having a second pattern on the second surface of the substrate 11 based on the alignment and etching the second surface of the substrate 11 in dry by using the second mask 17 to form the second support beams 20, a membrane member 22a where the first and second support beams 15, 20 are formed on both surfaces of the membrane 12 is manufactured. Consequently, it is possible to provide the membrane member that is sufficient in strength and is hard to be deformed by heat.

  • Patent number: 6795381
    Abstract: According to this invention, general addresses are given to a multi-layer information storage medium to facilitate handing of information. That is, it is possible to set generalized addresses for multiple information layers, and information indicating a condition for setting the general addresses, e.g., the contents of a disk ID zone in a rewritable zone of a lead-in area, is recorded on an information reproducing layer.

  • Patent number: 6767179
    Abstract: In a fuel pump having a high pump efficiency, an annular portion is formed on an outer periphery of an impeller to let one- and opposite-side blade grooves be independent of each other. Then, various improvements are made such as tilting front and rear wall surfaces of the blade grooves in a predetermined direction, forming one- and opposite-side blade grooves in a zigzag fashion, forming a guide surface in a communicating passage of a pump housing, and forming communicating holes in an impeller.
