  • Patent number: 5821625
    Abstract: The present invention reduces crosstalk, which occurs as a result of interference between signals running in each of respective wiring layers of a first semiconductor chip and a second semiconductor chip stacked surface to surface with a small gap. The semiconductor device includes a first semiconductor chip 1 having a first electrode pad 2 and a first wiring layer 9 in the main surface, and a second semiconductor chip 5 having a second electrode pad 6 and a second wiring layer 10 in the main surface confronting the first semiconductor chip. A bump 4 is provided for electrically coupling the first electrode pad 2 and the second electrode pad 6 together. An insulation layer 8 is disposed between the main surfaces of first semiconductor chip 1 and second semiconductor chip 5. An electro-conductive layer 7 is disposed between the main confronting surfaces of the first semiconductor chip and the second semiconductor chip.

  • Patent number: 4635541
    Abstract: A feed roller is usually rotated at a high speed; a return roller is fitted to a return shaft rotated at a low speed through a one-way clutch; a rocker roller driven at a high speed is brought into press-contact with the return roller so that the return roller is rotated at a high speed in accordance with the high speed rotation of the rocker roller thereby performing the primary tightening operation for a band; then, the return roller is engaged with the return shaft by the function of the one-way clutch when the rotational speed of the return roller coincides with that of the return shaft, thereby performing the secondary tightening operation with a strong pulling force. The strapping machine having the above mentioned construction provides noiseless and speedy operations for strapping the band around a package.

  • Patent number: 4218969
    Abstract: A strapping machine comprises a return roller having a high friction outer peripheral surface and a feed roller having a low friction outer peripheral surface which are contacted with each other under pressure and the return roller is disposed in free condition during the rotation of the feed roller in one direction and when the feeding resistance of the band is increased, the band is slipped on the outer peripheral surface of the feed roller to prevent the feeding of the band and in order to tighten the band around the package, both of the rollers are reversely rotated at a high speed to tighten the band around an object to be packed and then continuously rotated at a low speed to impart high torque to the band for an attainment of further tightening thereof.

  • Patent number: 4155799
    Abstract: A strapping machine comprises a roller for reversely rotating by a one way motor to tighten a package with a band, a differential reducing mechanism engaged to a clutch whereby the roller is reversely rotated at high speed before sliding the clutch and is further reversely rotated at low speed and high torque after sliding the clutch and a seal forming shaft starts when a return roller is stopped under a predetermined tension applied by tightening the band. The strapping machine further comprises a cutter anvil to contact the inner surfaces of the bands at the superposed part with a heating element inserted into the superposed part of the bands and a cutter for cutting the band under suitable tension after cooling the heat-sealed bands.

  • Patent number: 4011808
    Abstract: Automatic band strapping apparatus with a table for supporting an article during banding. An arch frame extends in the form of an upright loop from one side to another of the table. The arch frame has an elongated side wall also in the form of an upright loop in a plane substantially normal to the table. An elongated U-sectioned arch guide made of flexible plastics material such as ultra-high molecular polyethylene has a loop shape following the contour of the arch frame side wall, and one edge surface facing that side wall is opened by means of a groove. Springs press the grooved edge surface of the arch guide against the arch frame side wall thereby defining a band passage through the arch guide which is normally closed. The arch guide is locally separable from the side wall against the urgence of the springs, progressively around the length of the arch frame, providing a moderate draw-out resistance to enable release and withdrawal of band progressively and continuously from the band passage.
