  • Patent number: 4954257
    Abstract: The present invention relates to a reactor for biological purification of pollutant-containing water in a closed vessel by means of loop operation. This vessel contains, disposed vertically and concentrically with respect to its jacket and to each other, an insertable pipe that is open at both ends, into which a nozzle projects for the purpose of supplying the water-gas-biomass mixture to be purified, and a guide pipe that is open at both ends and that forms an inner annulus with the internal insertable pipe and an outer annulus with the reactor jacket. This guide pipe projects above and below the ends of the insertable pipe. A deflector plate is mounted below the insertable pipe but inside the guide pipe, so that part of the biomass-water mixture is deflected back into the inner annulus. A conically shaped sedimentation chamber is disposed in the lower part of the reactor.

  • Patent number: 4953648
    Abstract: A rear wheel steering mechanism for steering rear wheels of the vehicle is urged by a spring so as to allow the rear wheels to take a neutral position or a position at which the rear wheels run in a straight direction. Control over the driving of the motor connected to the rear wheel steering mechanism allows the rear wheels to be steered at a given steered angle against the urging force of the spring. The rear wheels are always returned to the neutral position by the spring by disconnecting a clutch interposed between the rear wheel steering mechanism and the motor whenever abnormality is found. Presence or absence of abnormality in a drive control system of the motor is checked or an alignment of a reference position of the motor is made, in such a state that the clutch is disconnected, immediately after an ignition switch was turned on yet prior to control of the rear wheel steering.

  • Patent number: 4953100
    Abstract: A component-mounted printed circuit board inspecting apparatus comprises an imaging device for picking up images of printed circuit board. Land images are extracted from the image of a bare printed circuit board and that of a component-mounted printed circuit board. On the basis of the shapes of the land extracted from the bare printed circuit board and those of the component-mounted printed circuit board, the positional relationship between a comonent mounted on the printed circuit board and the land thereon is determined. This positional relationship is utilized to decide if the component is mounted properly on the printed circuit board.
