Abstract: A continuous denitration apparatus by microwave heating comprises an oven into which microwaves are applied and a cylindrical rotary drum disposed horizontally and rotatably disposed inside the oven. The rotary drum has the outer peripheral surface composed of a honeycomb or porous sheet-like microwave dielectric member. Inside the oven are disposed a trough for storing a nitrate solution of a nuclear fuel material below the rotary drum so as to immerse a lower portion of the outer peripheral surface of the rotary drum in the solution stored inside the trough, a heater above the rotary drum so as to heat the outer peripheral surface of the rotary drum opposing the heater, and a scraper for scraping off a denitrated product formed on the outer peripheral surface of the roatray drum between the heater and the trough.

Abstract: The present invention provides an automatic seat-belt applying system for motorcars, comprising a guide rail located laterally relative to a seat and disposed on the vehicle body of a motorcar to extend along a path of movement of a seat belt and a self-propelled anchor movable along the guide rail for holding the seat belt at one end, the self-propelled anchor including a motor for moving the anchor along the guide rail, whereby the seat belt can be automatically applied around a crew sitting on the seat.

Abstract: A one-way clutch for a reduction-geared motor having a reversible electric motor and reduction gears allows an output shaft thereof to rotate in a normal direction and firmly prevents the output shaft from rotating in a reverse direction when the reversible electric motor is not fed. The one-way clutch includes a transmission gear supported on the output shaft wherein a sawtooth is provided on one side of the transmission gear. A clutch, axially movable relative to the output shaft, has a sawtooth facing the sawtooth of the transmission gear. The clutch also provides a radially located rotation-prevention portion. A compression spring is included for urging the clutch for the transmission gear in a direction along the axis of the output shaft. A stopper pin in the gear casing is inserted into the rotation prevention portion of the clutch. An electromagnet in the gear casing urges the clutch in a direction opposite to the direction urged by the compression spring when the electromagnet is fed.
