  • Patent number: 6987757
    Abstract: When a call is set between a first line switching network of a call-out side and a second line switching network of a call-in side, a first gateway, if receives a call setting message from the first line switching network, transmits a inquiry message to at least one of second gateway. Each of second gateway from which received the inquiry message transmits a response message to the first gateway when a second gateway itself can communicate a call setting message to the second line switching network. Thereafter, the first gateway selects a second gateway for transmitting the call setting message within the second gateways to which transmitted the response message, and transmits the call setting message to the selected second gateway.

  • Publication number: 20040241056
    Abstract: Hydrophobic silica fine powder is produced by pyrolyzing a silane compound to form a silica fine powder and hydrophobizing the silica fine powder with an organohalosilane in a fluidization vessel. Hydrophobized silica fine powder which flies out of the fluidization vessel is collected with a cyclone and bag filter which are held at a temperature of 100-500° C. An apparatus for carrying out the process is also provided. Under simple controlled conditions that involve holding the cyclone and bag filter for recovering fugitive silica from the fluidization vessel to temperatures of 100-500° C., the method and apparatus are able to recover essentially 100% of fugitive silica, thus increasing yield of the product and alleviating the burden on waste gas treatment.

  • Publication number: 20010033818
    Abstract: Hydrophobic silica fine powder is prepared by pyrolyzing a silane compound to give silica fine powder, then treating the silica fine powder with a hydrophobizing agent in a fluidization vessel containing at most 3 vol % of oxygen. The process effectively confers the pyrogenic silica with hydrophobicity.

  • Patent number: 4437002
    Abstract: A pyroelectric infrared sensor for use in intrusion alarm systems, including a pyroelectric ceramic element provided with two pairs of electrodes, of which the front electrodes are so configured as to permit a simplified printing process for higher productivity and lower production costs. The front electrodes each have a first region overlapping with a part of one of the back electrodes and a second region overlapping with a part of the other of the back electrodes, and are arranged adjacent to each other and are electrically insulated from each other. The first regions and the second regions of the front electrodes have a ratio of areas of approximately 1:1. The pyroelectric element is attached to a holding member which is so designed that the back electrode areas of the element are free from physical contact with any thermally conductive solid material that may detract from the thermal responsiveness of the element.

  • Patent number: 4001842
    Abstract: An electroluminescent screen comprising a plurality of continuous phosphor stripes running the length of the screen formed on a panel for a color cathode-ray tube by applying film containing photosensitive material onto the panel. A shadow mask is attached to the panel, and the mask and film are irradiated by light from a light source.The shadow mask has on its concave face which faces the light source apertures arranged in substantially parallel rows, the apertures along the length of each of the rows being separated from each other by thin beam-intercepting bridge portions. The area on the shadow mask irradiated by the light is limited to cover only a part of the length of the rows of apertures by a shield plate having an opening for limiting the path of the light.The shield plate is moved so as to move the irradiated area on the shadow mask along the length of the rows of the apertures.

  • Patent number: 3971043
    Abstract: An electroluminescent screen for a color cathode ray tube of the shadow-mask type having a plurality of light absorbing stripes and elemental light emitting electroluminescent stripes each separated by one of the light absorbing stripes is produced by locating a movable shield plate between a light source and shadow mask, the shield having an opening for limiting the path of light between the light source and the shadow mask. The shield plate is moved so as to move the irradiated area on the shadow mask along the length of rows of apertures of the mask. The light source is gradually inclined synchronously with the moving of the irradiated area on the shadow mask to be kept always substantially parallel to the rows of apertures in the irradiated area. The light source has a substantial longitudinal length and narrow width and moves transversely with respect to that length with predetermined amplitude and frequency during movement of the irradiated area across the mask.
