  • Patent number: 5240284
    Abstract: A steering column assembly for a vehicle includes a steering column, a stationary bracket and a guide member which allows the steering column to displace horizontally in a direction along a longitudinal axis of the vehicle. A pair of universal joints with a shaft connecting them are provided forward of the steering column for allowing variation in angle between the steering column and the shaft, the angular variation being caused by the horizontal displacement of the steering column. The shaft includes an outer sleeve and an inner shaft telescopically received in the outer sleeve. The outer sleeve and the inner shaft are connected in such a fashion as to allow the inner shaft to displace along an axis of the outer sleeve in response to the horizontal displacement of the steering column.

  • Patent number: 5130203
    Abstract: A method of producing a metal gasket includes steps of alkaline cleaning a metal plate, coating a non-rinse chemical for chromate conversion of surfaces of the metal plate and drying to form chromate films, coating an adhesive on the chromate films and drying or baking the adhesive to form adhesive layers, and coating a rubber compound of a sheet-like or an amorphous mixed compound to a predetermined thickness on the adhesive layers and heating and vulcanizing the rubber compound to form rubber coated metal plate. A metal gasket manufactured in this manner has a high bonding power of the rubber layers to the metal plate to obtain an improved durability for long use.

  • Patent number: 5078256
    Abstract: A chip collecting apparatus for a machine tool has two separate chip conveyors for chips of different materials. The chip collecting apparatus receives chips on fixed guide plates. Chips are washed from the fixed guide plates into a chip collecting area. In the chip collecting area is disposed a change-over plate for directing the chips from the guide plates onto either one of the chip conveyors. The change-over plate is pivotably moveable between different positions corresponding to the respective chip conveyors. In an alternative embodiment, only one chip conveyor is used, and the change-over plate is provided at the discharge end of the conveyor to discharge chips into either one of two chip collecting bins.
