  • Patent number: 5178194
    Abstract: A multiply connected air core coil winding apparatus is provided in which a winding core is protruded and retracted through a first side frame in order to position the winding core between the first side frame and a second side frame, the winding core being rotated when so positioned in order to form a side face of an air core coil. The second side frame is capable of being drawn towards and away from the first side frame. A pocket is provided at one of the side frames for housing the air core coil when the winding material has been completely wound. As a result, multiple air core coils can be wound without cutting the winding material of a first air core coil.

  • Patent number: 4202021
    Abstract: A front-loaded cassette tape deck which moves the cassette a greater relative distance than the distance travelled by the table. A table is normally in the fully projected position because the force provided by a pair of springs is greater than the frictional forces and the damping forces provided by damping pulleys. A cassette is placed in a slider and is held therein by a leaf spring. As the table is moved towards the closed position, the slider is moved by cords and pulleys at a faster rate than the table. Thus, the slider is moved relative to the table. The greater travel of the slider causes it to be moved within a holder by the sliding engagement of a plurality of guide members. During this time, the holder is at an upper position. When the table reaches the closed position, the slider is fully disposed within the holder. The holder with the slider then automatically rotates to a lower position, which puts the cassette into operational engagement with a cassette driving section.
