  • Patent number: 8882437
    Abstract: A non-contact holding device (1) attached to a parallel mechanism robot (100) has a square plate-like base member (10), a Bernoulli chuck (20) attached to the center on a rear surface of the base member (10), and eight pin-like guide members (30) that are disposed facing each other with the Bernoulli chuck (20) therebetween and that are provided on the rear surface of the base member (10) in a protruding manner. The guide members (30) facing each other are configured to be able to move away from each other. These guide members (30) move away from each other along inner surfaces of guide holes (72) of a workpiece mounting tray (70, 71) as the Bernoulli chuck (20) approaches a workpiece mounting surface (75) of the workpiece mounting tray (70, 71).

  • Patent number: 8813805
    Abstract: Provided is a filament winding apparatus (1) which moves a liner (2) while rotating the liner (2) and winds a fiber bundle (FB) around the outside peripheral face (2a) of the liner (2), said fiber bundle (FB) being guided by a fiber-feeding guide (44) positioned around the trajectory of the liner (2). The filament winding apparatus has a resin-spraying nozzle (45) for spraying a resin onto the fiber bundle (FB) at a position before the fiber bundle is wound around the liner (2), and the resin-spraying nozzle (45) is disposed so as to spray the resin onto the downstream side of the rotation direction of the liner (2) relative to an imaginary line (VL1) defied by a straight line connecting the spray nozzle (45N) of the resin-spraying nozzle (45) with the rotation axis of the liner (2).

  • Publication number: 20140037413
    Abstract: Provided is a suction chuck that is lightweight and that sucks and releases a thin plate workpiece in such a manner that the thin plate workpiece is not in contact with an edge of the chuck. A suction chuck according to an embodiment of the present invention includes a main body having a flat plate shape, and an opposing surface. Compressed air passages are formed within the main body. The opposing surface is a surface of the main body at the side facing the workpiece. The opposing surface has a plurality of recesses formed therein. The plurality of recesses serve as a sucking element for generating a negative pressure by ejecting the compressed air. The opposing surface is formed with a shape similar to the shape of the workpiece (or with a shape that corresponds to the shape of the workpiece being offset outward) such that the shape of the opposing surface is able to completely cover the shape of the workpiece when seen along a direction perpendicular to the opposing surface.

  • Patent number: 8456124
    Abstract: A parallel mechanism includes a base portion, a bracket to which an end effecter is attached, a plurality of actuators attached to the base portion, a plurality of arms through which the plurality of actuators and the bracket are coupled together in parallel, and a control device arranged to control the actuators. When the end effecter in a stopped state is moved to a target position, the control device is arranged to control the actuators so that a level of acceleration at which the end effecter is accelerated is higher than a level of deceleration at which the end effecter is decelerated.

  • Patent number: 7450155
    Abstract: The image capturing apparatus extracts and records an effective image Ap from a captured image Ao obtained by imaging of incident light from a subject on an image capturing element by an optical system composed of optical members. When an angle of view of an image that is to be recorded is large, the image capturing apparatus adjusts an angle of view of the effective image Ap by an optical zoom unit and records the effective image Ap while correcting camera shake by a mechanical camera-shake correction unit. Only when a magnification of the optical zoom unit for the captured image Ao is maximal, the image capturing apparatus further adjusts the angle of view of the effective image Ap by an electronic zoom unit and records the effective image Ap while correcting camera shake by an electronic camera-shake correction unit.

  • Patent number: 7450154
    Abstract: In an electronically zoomable digital camera having a hand shake correction mechanism, when electronic zoom operates, pixel shift is carried out in such manner of capturing a reference image and then capturing a shifted image after moving an image capturing element from the reference image by a prescribed amount of shift by means of the hand shake correction mechanism and thereafter interpolating pixels of the shifted image between pixels of the reference image. The amount of shift is changed according to a magnification of the electronic zoom. The hand shake correction mechanism has a continuous mode in which the movement is effected by a continuous amount and a fixed amount mode in which movement is effected by only a fixed amount and is driven in the fixed amount mode when the pixel shift is carried out.
