  • Patent number: 5862592
    Abstract: A cage for a roller bearing which is free of fretting and abnormal noise, which can be manufactured at low cost, and which can be easily mounted in the bearing. The cage is formed by bending a metal sheet having pockets into a ring shape, temporarily joining its ends, heat-treating the ring thus formed to remove stress, and separating the temporarily joined portion. Such a cage tends to rotate slower than the raceway members on the driving side of the bearing, making it possible to reduce fretting. Such a cage can be used under high-temperature conditions.

  • Patent number: 5816790
    Abstract: A heavy oil emulsified fuel combustion furnace is provided which prevents lowering of combustion efficiency due to water content in the fuel as well as prevents elevation of sulfuric acid dew point due to water content in the flue gas of the combustion furnace. In the apparatus a heavy oil emulsified fuel (102) is heated by a heater (110) using a heat pipe etc. and then is separated by a water vaporizer (120) into heavy oil (122) and vapor (121) consisting of steam and a light oil combustible gas. The heavy oil (122) is supplied to a burner port of the combustion furnace, such as a boiler etc. The vapor (121) is condensed by a condenser (140) to produce liquid (141) comprising a mixture of water and light oil. The liquid (141) is separated by an oily water separator (150) into oil (151) and water (152). The oil (151) is used as a fuel for an igniting torch of the combustion furnace 10 and the water (152) is used partially as cooling water (41) for an SO.sub.

  • Patent number: 4284721
    Abstract: An improvement in a method for manufacturing dipeptides from an N-substituted aspartic acid and a phenylalanine lower alkyl ester. The two starting materials are allowed to react with each other in the presence of an immobilized metallo-proteinase in an organic solvent immiscible with water. The enzyme can be recovered for reuse thereof. The loss of materials due to the hydrolysis of the phenylalanine lower alkyl ester is reduced, so that use of the phenylalanine lower alkyl ester in a nearly stoichiometric quantity suffices for the reaction to ensure an improved yield and reduction in cost of industrial production.

  • Patent number: 4224542
    Abstract: Fixed members of the small-sized motor centrifugal governor switch and commutator segment metals are secured to a boss of a molding insulating resin mounted on a shaft of the rotor, thereby disposing the centrifugal governor switch on the same side as the commutator with respect to the rotor. With this construction, there is no need of installing the centrifugal governor switch in the space radially centrally of the stator magnet, hence there is no need of restricting the size of the centrifugal governor switch to be smaller than the inner diameter of the stator magnet. Accordingly the centrifugal governor switch can be made larger, thereby securing a better function.

  • Patent number: 4192452
    Abstract: A television camera for picking up a bar coded label is controlled to produce scanning lines contacting each other as by halving its vertical sync frequency, producing an elliptical beam, alternating narrow beams with wide beam, or utilizing wobbling technique. Also a raster formed of the scanning lines is stepwise rotated by a pulse motor. Alternatively a pair of horizontal and vertical deflection coils disposed in quadrature relationship with the other pair of similar coils are supplied with sawtoothed deflection currents varying in amplitude at predetermined equal intervals and in quadrature relationship with similar current supplied to the other coil pair. For spaced scanning lines, a video signal from the television camera affected by its after-images is blocked by a gate. Alternatively, the signal is subtracted from a video signal due to the preceding scanning line correlative to the same to remove the effect of the after-images.
