  • Patent number: 4820465
    Abstract: In a method for producing shaped synthetic members, one begins with superficially plasticized synthetic granulated material in manner known per se. This is sintered to form a preform in a first operation in a preliminary chamber. The preform is then extruded by way of a narrow nozzle into a moulding cavity, the nozzle cross section being so narrow that on the way between the preliminary chamber and the moulding cavity, the individual granular particles must be deformed mechanically. The moulding cavity is then filled by one or more thin strands, which consist of solid, but mechanically deformed and superficially plasticized granulated particles.

  • Patent number: 4818095
    Abstract: The effect of the glasses of this invention is estimated and is summarized as follows:(1) The effect of reducing the consciousness of eye fatigue is seen.(2) There is a tendency that the mental subjective symptoms are reduced.(3) Because the sense of fatigue is reduced, concentration becomes easier and it is presumed that it is helpful in preventing irritation and weariness.Since fatigue differs depending on the length of working time, it seems to be necessary to take into consideration the effect due to other fatigue than eye fatigue and the effect of motivation. It seems also necessary to investigate under different conditions the latent fatigue which has not been covered in this report.

  • Patent number: 4812211
    Abstract: A relatively great number of materials such as forged or cast motor parts of relatively small sizes are loaded into a basket. The basket is suspended from a front conveyor, and is conveyed thereby to a position in front of a coating section comprising a plurality of tanks arranged in a required order and containing liquids required for the coating. After reaching the foregoing position, the basket is carried by, or suspended from, a basket carrier and is immersed in the liquids in the tanks in the order of arrangement thereof. The basket is swung in each tank several times. After being immersed in the liquids in all tanks, the basket is conveyed, by a rear conveyor, to a furnace for baking the materials coated. The basket is passed through the furnace, and then is suspended again from the front conveyor and conveyed thereby to a section where the basket is overturned to unload the materials coated and baked. Then, the basket, which is now empty, is conveyed to the initial position.
