  • Publication number: 20090235941
    Abstract: A flavor bead includes a particulate carrier, a glucan film supported by the particulate carrier, and a flavorant. The flavorant is supported by the flavor bead such that release of flavor from the flavorant is suppressed by the glucan film, but the flavor is released by the glucan film being at least partially dissolved when the glucan film contacts with tobacco mainstream smoke.

  • Patent number: 6829816
    Abstract: A compact and highly reliable nonreciprocal circuit device can be manufactured at low cost. Marking is clearly performed on a surface of the nonreciprocal circuit device. In a method of manufacturing the nonreciprocal circuit device, after components constituting the device are joined together, solder is applied at portions where the components are bonded with each other. The magnetic force of a permanent magnet is adjusted and then laser marking is performed on a surface of a metal case. Next, the nonreciprocal circuit device is heated to perform together solder bonding, thermal aging of the permanent magnet, and the removal of stains left due to marking. Then, after checking the characteristics of the device, delivery inspection is conducted to complete the manufacturing process.

  • Patent number: 5265984
    Abstract: A method for reducing pressure losses in a cyclone separator includes introducing a gas entraining a particulate material into a duct connected to the cyclone separator, separating at least a portion of the particulate material through an opening formed in a bottom surface of a horizontally extending section of the duct in proximity to a junction point of the duct to the cyclone separator, and introducing the gas entraining the particulate material into the cyclone separator. A ducting system for the cyclone separator includes the duct and the opening. The particulate material is prevented from being deposited and heaped in the vicinity of the junction point.

  • Patent number: 4693839
    Abstract: Disclosed herein is novel metal rolling oil compositions comprising lubricant oil components and specific type of water-soluble cationic or amphoteric polymer compounds, which are selected from the group consisting of polymer compounds having at least one recurring unit and having an average molecular weight of from 1,000 to 10,000,000.The thus obtained metal rolling oil composition gives a stable size distribution of relatively large sizes under agitating conditions of high shearing force and is useful as a rolling oil having a high lubricating and rolling performance with a reduced timewise change.
