  • Patent number: 9903278
    Abstract: An apparatus for estimating operating parameter of a gas-turbine aeroengine is configured to calculate a rotational speed of the low-pressure turbine (N1) by retrieving preset first characteristics by at least a rotational speed of the high-pressure turbine (N2), an engine inlet temperature and a first amount of bled air, to calculate a compensating value (?N1) of the rotational speed of the low-pressure turbine by retrieving preset second characteristics by at least a second amount of bled air, and to calculate the rotational speed of the low-pressure turbine (N1) finally based on the calculated rotational speed of the low-pressure turbine (N1) and the compensating value (?N1) thereof.

  • Patent number: 9761418
    Abstract: A plasma processing apparatus for exciting a processing gas by a microwave, includes a focus ring extending in an annular shape, a first tubular member being wrapped around a central axis to extend along an outer periphery of the lower electrode below the focus ring, an annular member made of a dielectric material provided between the focus ring and the first tubular member a second tubular member extending along an outer periphery of the first tubular member and a choke portion suppressing a microwave propagating through the first tubular member via the focus ring and the annular member. And the choke portion protrudes outward in a diametrical direction of the first tubular from the outer periphery of the first tubular member and extends in an annular shape along the periphery of the first tubular member, the choke portion is covered by the second tubular member.

  • Patent number: 9646867
    Abstract: A plasma processing apparatus includes a mounting table including a lower electrode and an electrostatic chuck, a high frequency power supply electrically connected to the lower electrode, a heater provided in the electrostatic chuck, a heater power supply for supplying a power to the heater, a filter unit including a filter connected to the heater power supply, a rod-shaped power feeder connecting the heater power supply and the heater via the filter, an insulating tubular portion having an inner hole through which the power feeder extends, and a conductive choke portion serving to suppress a microwave propagating through the tubular portion. The choke portion includes a first portion extending from the power feeder in a direction intersecting with a longitudinal direction of the power feeder and a cylindrical second portion extending, between the tubular portion and the power feeder, from a peripheral portion of the first portion.

  • Patent number: 5464828
    Abstract: The invention is an aqueous suspension of sucralfate (sucrose sulfate aluminum salt), which is added with a starch and/or a derivative thereof and preferably further with a cellulose derivative, polysaccharide gum, alginic acid, alginate and/or bentonite, whereby the suspension is made stable for a long time and may be redispersed if necessary. The invention can thus provide a liquid pharmaceutical preparation useful for protecting ulcer areas on mucous membranes of the stomach and duodenum industrially for the first time, although solid pharmaceutical preparations have been available.
