  • Patent number: 7868254
    Abstract: A manufacturing method of a flat shield cable has a step of arranging a plurality of flat conductors including a ground line parallel with each other in one plane at a pitch P, a step of forming a flat cable by laminating a first insulating film on the flat conductors from both sides of an arrangement plane of the flat conductors, a step of laminating a shield layer on outside surfaces of the flat cable, and a step of electrically connecting the ground line to the shield layer. The manufacturing method further has a step of cutting the ground line at a portion other than in the conductor exposure portions and folding cutting portions of the ground line to outside the first insulating film before laminating the shield layer, and a step of electrically connecting only the folded ground line among the flat conductors to the shield layer.

  • Patent number: 7841591
    Abstract: A sheet-supplying device has a sheet-accommodating tray, a raising/lowering unit, a first position sensor, a second position sensor, a controlling unit. The raising/lowering unit raises and lowers the sheet-accommodating tray substantially. The first position sensor detects a first position indicating a position in the stacked direction of one end portion of a topmost sheet stacked in the sheet-accommodating tray. The second position sensor detects a second position indicating a position in the stacked direction of another end portion of the topmost sheet. The controlling unit controls the raising/lowering unit to raise or lower the sheet-accommodating tray based on both the first position detected by the first position sensor and the second position detected by the second position sensor so that one end of the topmost sheet in the stacked status is positioned at a prescribed position in the stacked direction.

  • Patent number: 7814659
    Abstract: In a method of manufacturing a dynamic bearing assembly having a shaft and a sleeve whose inner circumferential surface faces an outer circumferential surface of the shaft, the shaft is inserted into a bearing hole from an upper end opening toward a bottom end opening of the bearing hole. Upon inserting the shaft into the bearing hole, fluid is fed from the bottom end opening toward the upper end opening of the bearing hole with a fluid feed apparatus.
