Abstract: The present invention provides a hot-dip Al-plated steel sheet for fuel tanks excellent in air-tightness after welding and corrosion resistance subsequent to forming. The present invention provides, as concrete means, a hot-dip Al-plated steel sheet comprising a steel sheet comprising up to 0.003% of C, up to 0.03% of Si, up to 0.3% of Mn, up to 0.02% of P, up to 0.006% of N, up to 0.1% of Ti, Ti and Nb in a total amount of at least the atomic equivalent of (C + N) and up to 0.2%, 1 to 30 ppm of B, and the balance Fe and unavoidable impurities, and a plating layer comprising 2 to 13% of Si, and the balance  Al and unavoidable impurities on the surface of the steel sheet, the steel sheet showing a total elongation of at least 45% after plating. Alternately, the hot-dip Al- plated steel sheet may have a chromate coating in an amount of 5 to 100 mg/m2 on the surface, and it may also have a resin coating on the top surface. As a result, the  Al-plated steel sheet is excellent in elongation after Al plating. The Al-plated steel sheet is, therefore, significantly excellent in corrosion resistance subsequent to forming in the internal environment of fuel tanks compared with conventional steel sheets. Accordingly, the  Al-plated steel sheet also having excellent air-tightness after welding is most appropriate as a material for fuel tanks of automobiles.

Abstract: A brush seal (1, 101) seals a circumferential gap (S1) between two relatively rotatable machine components (2, 102; 3, 103), such as the rotor or a shaft and a stator of a fluid flow ma-chine, such as a gas turbine engine. A plurality of seal bris-tles (4, 104) are fixed in a bristle holder (5) in an annular shape, and are mounted on the stator (3, 103) so that the free bristle ends (7, 107) extend toward and provide a seal against a seal surface (9, 109) of the rotor (2, 102). Each bristle includes a middle body portion (4A) that is tilted at a first tilt angle (.alpha.1) in the circumferential direction following the rotation direction, and the free bristle end (7, 107) is bent or angled relative to the tilted body portion (4A) so as to extend at a second tilt angle (.alpha.2) which is smaller than the first tilt angle (.alpha.1). Preferably, the first tilt angle (.alpha.1) is in the range from 30° to 60°, while the second tilt angle (.alpha.2) is in the range from 0° to 15°. The bristles may further be tilted in an axial direction at an angle (.beta.) relative to a radially extending plane. Since the free bristle ends (7, 107) extend substantially perpendicularly to the seal surface (9, 109), the seal effective-ness and the elastic resiliency of the brush seal are maintained, and the bristles are not damaged, independent of the rotation direction of the rotor.

Abstract: An apparatus for counteracting vibrations includes a housing for attachment to a vibrating member. First and second bodies are connected to the housing by first and second springs, respectively, with a combined stiffness which defines a resonant frequency at which the first and second bodies oscillate with respect to the housing. Each of the first and second springs include a plurality of rods fixedly connected between a pair of rings. A lever engages the first and second bodies to vary a spacing between those bodies when force from an actuator is applied to the lever. The lever action alters the stiffness of the first and second springs which varies the resonant frequency of the vibration absorber.

Title: Telephone communication method capable of relating a telephone terminal and a speech channel ip address at the time of call connection
Inventor: NAKAJIMA TOSHIKATSU

Granted: 2006-01-24
Abstract: A telephone communication method capable of promoting the efficient use of the limited number of IP (Internet Protocol) addresses is disclosed. When a call is originated on a first telephone terminal, a first gateway accommodating the terminal accesses a DNS (Domain Name System) server via a UDP (User Datagram Protocol) channel of Internet or Intranet. The first gateway inquires the DNS server of the IP address of a second gateway accommodating a telephone terminal to be called, using an office number assigned to the second telephone terminal as a host name. The DNS server returns the IP address of the second gateway to the first gateway via the UDP channel. In response, the first gateway selects its own IP address for speech transfer and sends a call connection request to the second gateway on a TCP (Transmission Control Protocol) channel of Internet. On receiving the request, the second gateway determines whether or not the second telephone terminal is busy, and selects the IP address for speech transfer if it is idle. The IP address selected is returned to the first gateway in the form of a response message. As a result, a connection is set up between the two telephone terminals.

Abstract: La présente invention concerne un appareil de chromatographie en phase liquide sous haute pression. Avec cet appareil, on charge dans la colonne un mélange fluide contenant au moins un soluté capable de réagir avec les surfaces de réaction chromatographique de la colonne, à la suite de quoi on injecte dans la colonne un certain nombre de giclées de différents fluides d'élution. Les injections se font de façon à ramener à un minimum la quantité requise de fluides d'élution. Selon une réalisation, les injections sont pratiquées de façon à garantir que l'écoulement ne porte que sur les fluides d'élution traversant la colonne avec un front de vague sensiblement plan, et à des vitesses correspondant à des vélocités réduites supérieures à environ 5.000, c'est-à-dire avec un débit suffisant pour induire dans ces fluides un flux de turbulence. Cela permet de ramener à un minimum le durée nécessaire pour que la totalité de la suite des mélanges et fluides d'élution traverse la colonne. Selon d'autres réalisations, les injections se font sensiblement simultanément en des points spatialement distincts situés à proximité de l'entrée de la colonne ou en séquence en un point unique situé à proximité de l'entrée de la colonne. Dans l'un comme dans l'autre cas, les fluides ont alors tendance à traverser la colonne selon une vélocité de groupe commune, à la manière de giclées de fluides intimement regroupées.

Abstract: An improved apparatus and method for measuring the concentration of hydrogen peroxide vapor or gas in a sterilization chamber.  The hydrogen peroxide is measured spectrophotometrically in the ultraviolet region between 200 and 400nm.  Because water vapor does not absorb in the ultraviolet region, it does not interfere with the determination of the concentration of the hydrogen peroxide vapor.  Although organic compounds have absorbances in the ultraviolet region, the organic compounds are removed by evacuating the sterilization chamber to low levels before doing the hydrogen peroxide determination.  The ultraviolet light source is either a low pressure mercury vapor lamp with an emission at 254 nm ora deuterium lamp with an optical filter selective of 206 nm light.  A movable gas cell can be used to measure the hydrogen peroxide concentration at various areas in the sterilization chamber.  The measurement system can be combined with a feedback loop to control the concentration of hydrogen peroxide in the sterilization chamber.

Abstract: A process for the production of methanol comprises converting a hydrocarbon feedstock at a pressure above the desired synthesis pressure into a synthesis gas mixture containing hydrogen, carbon oxides and steam at an elevated temperature and pressure, cooling said mixture to condense water from the mixture, separating the condensed water, and passing the resultant gas mixture, with no further compression and no recycle of unreacted gas, at an elevated temperature through a series of at least two methanol synthesis stages with separation of synthesised methanol from the gas mixture after each stage. The hydrocarbon feedstock is converted into the synthesis gas mixture by a catalytic steam reforming process wherein the heat required for reforming is supplied by the products of combustion of the unreacted gas remaining after separation of synthesised methanol, and, preferably also by the reformed gas after it has left the reforming catalyst.
