    Abstract: First of all, in a first step S1, each actuator command value for position command value and posture command value of an end-effector is determined. Next, in a second step S2, rotational resistance values of a first and a second universal joints are obtained, and in a third step S3, the force and the moment exerted to each of the second universal joints are computed using this, and in a fourth step S4, the resultant force and the resultant moment exerted to the end-effector are determined from these. Then, in the fifth step, the elastic deformation amount of a mechanism is computed using these, and a compensation amount of the actuator command value is computed using these values. And then, in the sixth step, the actuator command values determined in the first step are updated with the compensation amount determined in the fifth step taken into account.

    Abstract: Kinematic parameters of a parallel kinematic machine can be estimated with high precision considering thermal displacement and error of a measuring device, in addition to deformation error caused by self-weight of each component. A DBB device is used when end effectors of a parallel kinematic mechanism machine are positioned at plural positions and in plural postures. In the DBB device, a plurality of support bars are provided with rigid balls on the both ends. One of the balls is fixed on a table and the other ball is provided with an end effector. The position, posture, and distance from a fixed position are measured and based on the measured value kinematic parameters are estimated. In estimating the kinematic parameters, any of deformation error caused by self-weight of each component, thermal displacement of each component, error of a measuring device are added for computation by linear approximation.

    Abstract: A curtain airbag capable for preventing occupant ejection from a vehicle, particularly in the vicinity of a rearmost seat, while reducing the output required of an inflator associated with the airbag. The curtain airbag is stored at an upper position on a side surface portion of the occupant compartment of the vehicle, so as to be inflated and deployed along the side surface portion. The curtain airbag includes an inflation region and a wide portion in the form of non-inflatable cloth. The wide portion is attached to a rear edge portion of the inflation region and also attached to at least one point of the vehicle rearward of a front-side pillar, the front-side pillar being located forward of rearmost side window. The wide portion has a shape that allows it to be strained, by the inflated and deployed inflation region, into a generally planar configuration over an assumed strike area of the rearmost side window.

A front strap is provided between a seam portion that divides a front chamber positioned at an end of a vehicle longitudinal direction from an adjacent main chamber, and a front pillar positioned at the end of the vehicle longitudinal direction so as to connect the seam portion to the front pillar, on an outer surface of the front chamber. A height position of a first connecting portion (P) between the front pillar and the front strap is set to be higher than a height position of a second connecting portion (Q) between the seam portion and the front strap. The front strap is set to be shorter than a length between the first connecting portion and a position to which the second connecting portion tries to move according to the inflation and deployment if the front strap is not present, and is stretched substantially linearly between the first and second connecting portions by the inflated and deployed front chamber.

    Abstract: When calculating a compensation value for a geometric error, a first index representing an order of connection of drive axes in a machine and a second index representing an order of connection of the drive axes including the geometric error are obtained. Then, a first vector is obtained by performing a matrix operation of a reference vector according to information on the connection in the first index, and a second vector is obtained by performing the matrix operation of the reference vector according to information on the connection in the second index. Thereafter, a difference between the first vector and the second vector is obtained as the compensation value.

    Abstract: A method for identifying geometric errors with respect to at least two translational axes and at least one rotational axis of a machine using a control device is disclosed. The method comprises the steps of: measuring positions of a jig in three-dimensional space using a position measurement sensor, wherein a measurement is carried out when the jig being indexed around the rotational axis by a plurality of angles is located at the positions; approximating a plurality of measured values of the positions measured in the measuring step to a circular arc; and calculating an error in regard to a center position of the rotational axis and/or a tilt error in the rotational axis, and tilt errors in the translational axes, based on the circular arc resulting from the approximating step.

    Abstract: The present invention provides a method and the like that are capable of calculating a correction value for a rotational axis and make it possible to correct an error in position or position and posture of a tool, which results from a geometric error, correct an error in posture of the tool, and also enhance the accuracy in machining by preventing a translational axis from operating in an infinitesimal manner due to a correction command. In a machine tool having two or more translational axes and one or more rotational axes, a correction value for each of the translational axes is calculated using a command position of each of the rotational axes, a coordinate value of a correction reference point as one point designated in advance in a command position space of each of the translational axes, and a geometric parameter representing the geometrical error.
