  • Patent number: 4419003
    Abstract: An electrostatic printing apparatus of the pressure fixing type having a toner image formed on a recording sheet fixed by applying pressure, including a tension imparting device for imparting to the recording sheet a tension oriented in the direction of travel of the recording sheet and a tension oriented in a direction perpendicular to the direction of its travel, and a regulating device for regulating the angle and posture of the recording sheet located in the path of movement of the recording sheet immediately before a pressure fixing roller device. The recording sheet is kept in taut condition as it is fed to the pressure fixing roller device to enable wrinkling, jamming and skewing of the recording sheet to be avoided.

  • Patent number: 4321679
    Abstract: A work setting system associated with a group of machine tools arranged in a production line for setting workpieces on pallets. The system includes a setting table section providing a location for setting a workpiece on a pallet, a work centering and clamping unit arranged around the setting table section for driving positioning jigs and clamping members to be attached on the pallet, a measuring unit measuring the dimensions of the workpiece on the pallet and supplying signals to the work centering and clamping unit which represents the measurements of the workpiece as positioning signals, a handling unit for handling the pallets, the workpieces and the jigs, and a control unit for controlling the work setting table section, the centering and clamping unit, the measuring unit and the handling unit in a conversational mode and also supplying and receiving information exchanged between control unit for the group of machine tools and a central processing unit superposing the control units.

  • Patent number: 4134444
    Abstract: Automatic molten metal pouring apparatus comprising molten metal level detector, mold position detector, ladle tilting angle detector, a ladle tilting servomechanism and a control device. The apparatus permits a suitable pouring flow rate of molten metal to be automatically poured into each of the molds of different types which may be conveyed one after another to the pouring position along the casting line.

  • Patent number: 4025060
    Abstract: A molten metal pouring device is disclosed, wherein there are provided two pairs of link mechanisms whose links are adapted to be moved in parallel relation to each other, so that, regardless of an inclined angle of a ladle, a molten metal-dropping locus may follow a constant path when a molten metal is poured from a ladle into a mold. The molten metal pouring device equipped with these link mechanisms can be readily automated, as well as permits the reduction in cross sectional area of a sprue of a mold. Thus, temperature drop of a molten metal is avoided, with the result of production of castings of an improved quality.
