  • Publication number: 20100296985
    Abstract: A microreactor is configured to have a metal substrate having a microchannel portion on one surface thereof, a heater provided on the other surface of the metal substrate via an insulating film, a catalyst supported on the microchannel portion, and a cover member having a feed material inlet and a gas outlet and joined to the metal substrate so as to cover the microchannel portion. Since the microreactor uses the metal substrate having a high thermal conductivity and a small heat capacity, the efficiency of heat conduction from the heater to the supported catalyst becomes high, and the processing of the metal substrate is easy to facilitate the production.

  • Patent number: 7665499
    Abstract: In a laminating apparatus for a ceramic green sheet according to the present invention, cutting means and laminating means are positioned on a conveying path of a carrier film conveyed by conveying means. Specifically, cutting of the ceramic green sheet and lamination of sheet pieces are carried out on a single conveying path. Consequently, the reduction of production efficiency is prevented significantly. Furthermore, the position of the cutting means and the position of the laminating means are different. Therefore, even when cut scraps are generated when the ceramic green sheet is cut by the cutting means, the cut scraps are significantly prevented from entering between layers in a green sheet laminated body.

  • Publication number: 20100025273
    Abstract: A medical device holder is comprised of a flexible elongated sheet member, and includes a holding portion configured to hold a three-dimensionally configured part connected of the device. The holding portion is configured to bend back on itself to cover the three-dimensionally configured part. A slit is provided in the sheet member to allow insertion of the distal end portion of the holding portion so that the state in which the holding portion covers the three-dimensionally configured part connected can be maintained. The distal end portion of the holding portion is folded toward the opposite direction from the direction to pull out when retrieving the catheter from the sheet member.

  • Publication number: 20090218927
    Abstract: A fluorescent lamp is configured so that a glass bulb has a phosphor film formed on its internal face, and a rare gas and an amalgam pellet are enclosed therein. The amalgam pellet contains zinc, tin, and mercury as principal components, one amalgam pellet is enclosed in the glass bulb, and the amalgam pellet has a weight of not more than 20 mg. The fluorescent lamp satisfies the relationship expressed as: 45×(1?A)?x?55×(1?A), 75A?y?85A, 45?30A?z?55?30A, and x+y+z?100, where x represents a content of zinc contained in the amalgam pellet in percent by weight, y represents a content of tin therein in percent by weight, and z represents a content of mercury therein in percent by weight. This configuration allows the fluorescent lamp to be characterized in that an amount of released mercury that is necessary for the first lighting of the fluorescent lamp is secured, and that the phosphor film is less prone to being peeled due to the amalgam.
