Abstract: A gripping device includes: a palm portion; a plurality of finger portions protruding from a periphery of the palm portion and configured to fall toward the palm portion by deforming the palm portion in a thickness direction; a connecting portion formed in a position surrounding an outer edge of the palm portion on a side opposite to a side formed with the finger portions, the connecting portion connected to a case; a high-strength portion provided between the palm portion and the connecting portion, the high-strength portion having a predetermined length from the outer edge of the palm portion in the thickness direction of the palm portion, and the high-strength portion being less likely to be deformed than the palm portion; the case connected to the connecting portion, the case coming into contact with a base end of the high-strength portion; and an actuator configured to deform the palm portion.

Abstract: There is provided a gripper, a gripping device, and an industrial robot that can more reliably grip a workpiece without using a granular material. The gripper includes integrally: a palm portion; a plurality of finger portions protruding from a periphery of the palm portion and configured to fall toward the palm portion by deforming the palm portion in a thickness direction; a connecting portion formed in a position surrounding an outer edge of the palm portion on a side opposite to a side formed with the finger portions, the connecting portion connected to a case; and a high-strength portion provided between the palm portion and the connecting portion, the high-strength portion having a predetermined length from the outer edge of the palm portion in the thickness direction of the palm portion, and the high-strength portion being less likely to be deformed than the palm portion.

Abstract: A gripping device includes a bag-shaped gripping body, a plurality of elastic portions, and a shape holding portion. The gripping body includes a palm portion, and a plurality of finger portions protruding from a periphery of the palm portion and configured to fall toward the palm portion by deforming the palm portion in a thickness direction. The plurality of elastic portions is respectively provided in the plurality of finger portions, each of the plurality of elastic portions having a shape of each of the plurality of finger portions. The shape holding portion is provided in the gripping body to prevent contraction of an outer periphery of the palm portion. The shape holding portion includes a guide bore for receiving the palm portion when being deformed, and a curved portion provided on an outer side of a distal end of the shape holding portion in an axial direction of the guide bore. The distal end faces the plurality of finger portions.

Abstract: In a course guidance system for use in an automobile, for example, which includes an electronic display, a map, a direction sensor, a speed sensor and the like for deriving the present location of the car and plotting it on the display, the invention provides a course guidance system for a car which causes a linear and/or rotational movement of the driving locus displayed on the display when the map is changed or reset so that the present position can be easily located on the map.

Abstract: A course guidance system includes a direction sensor and a speed sensor both fitted to a moving body, a display mounted in the moving body and a map displayed in a manner corresponding to the display surface of the display and in which the present position of the moving body is derived by the direction sensor and the speed sensor and is plotted on the display in a manner corresponding to the map.

Abstract: A composite material comprising polyvinyl chloride, talc and a polyamide and/or amide compound is disclosed. The talc used is comprised of 85% or more by weight of particles having a diameter of 10 microns or less. The polyamide used has a softening point of less than 200.degree. C. The amide compound used is in preference alkylene bis-amide or methylolated aliphatic amide. The composite material contains up to 30 parts by weight of the polyamide or the amide compound per 100 parts by weight of the talc used. The disclosed polyvinyl chloride composite material has an improved impact strength and improved thermal stability.
