  • Patent number: 10660504
    Abstract: In a flexible tube insertion apparatus, at least one circuit determines whether an S-shape is formed in an insertion section based on a shape information of the insertion section detected by a detector, determines whether an intersection angle between an extension line of a central axis of the insertion section and a tangential line for the insertion section at an inflection point is enlarged or not based on the shape information, and determines whether or not the stiffness variable portions are provided in a position of the S-shape in the insertion section when it is determined that the S-shape is formed and the intersection angle is enlarged. A stiffness controller increases a stiffness of the stiffness variable portions included in the position of the S-shape in accordance with the determination of the circuit.

  • Patent number: 10661737
    Abstract: An energy storage apparatus includes: an energy storage device which is connected to a vehicle load and a vehicle power generator; a current interrupt device that causes the energy storage device and the vehicle load as well as the energy storage device and the vehicle power generator to be in a conduction state or in an interruption state; a voltage detection unit that detects voltage of the energy storage device; and a control unit. The control unit executes: a switching instruction process in which, when determining that the electric storage device will reach an overcharge state on the basis of the voltage, the control unit issues an interruption switching instruction to the current interrupt device; and an interruption maintaining process in which, when the number of times of the switching instruction process exceeds a predetermined value, the control unit issues an instruction to maintain the interruption state.

  • Patent number: 10650173
    Abstract: A design support apparatus supporting designing of a product which uses a fiber material includes a processor that creates a predicted shape model by predicting a shape of the product before a deformation processing. The processor: creates a 3-dimensional shape model of the product; creates curved shape models by separating the 3-dimensional shape model into two or more fiber layers; sets a correspondence relationship between the curved shape models; creates an orientation vector field in the curved shape models; and predicts the shape of the product before the deformation processing by developing the curved shape models on a flat surface based on the correspondence relationship between the curved shape models and the orientation vector field in the curved shape models, and creates the predicted shape model based on the predicted shape.
