Abstract: A machining center processes a section not to be corrected of a workpiece and a crankshaft bearing hole in a different position from the section not to be corrected and which is separated from an upper deck surface of the workpiece. The machining center supplies a coolant to the hole during processing and detects a temperature of the coolant. A control apparatus estimates the temperature of the coolant when a predetermined time elapses from a start of the processing to be a temperature of the workpiece, calculates a deformation amount of the workpiece due to thermal expansion, corrects a position of the hole with respect to the upper deck surface based on the deformation amount, and starts processing of the hole after the predetermined time. The predetermined time ends when a difference between a temperature near the hole and the temperature of the coolant falls within a predetermined range.

Abstract: A vehicle front structure comprises a beam member and a plate member. The plate member comprises a vertical face portion, a body portion extending forwardly from the vertical face portion, a front end portion positioned at a front end of the body portion, and a protrusion face portion provided to be forwardly spaced apart from the vertical face portion. The front end portion comprises an upper section located at a higher level than the body portion. The protrusion face portion comprises a protrusion-face-portion upper section located at a higher level than an upper end of the upper section and a protrusion-face-portion lower section located at a lower level than the upper end of the upper section. The protrusion-face-portion lower section is configured to have lower strength against a collision load applied from a vehicle forward side than the protrusion-face-portion upper section.

Abstract: To suppress damage on a bonnet at light collision, a vehicle-body structure includes rear-portion crush cans that perform compressive deformation when a first predetermined load is applied, and front-portion crush cans that perform compressive deformation when a second predetermined load smaller than the first predetermined load is applied. A front portion of a bonnet is positioned on a vehicle rear side of front portions of the rear-portion crush cans.

Abstract: A terminal structure includes mutually adjacent first and second terminals, each having a connecting part for electric connection to an external apparatus, and a case accommodating the terminals and having a tool insertion opening. The connecting parts have a flat connecting surface. When first and second virtual planes along the connecting surfaces and first and second normal lines to the connecting surfaces are drawn, the virtual planes intersect with each other at an obtuse angle, and when viewed from one side in a direction in which a line intersection between the virtual planes extends, the normal lines pass through the opening and intersect with each other at an opposite side of the disposed positions of the connecting parts with respect to a position at half of the shorter one of first and second distances from the first and second virtual planes to the opening.

Abstract: A controller detects partitioning lines OL and BL of a road and a road edge E based on an image taken by a camera, generates a pair of left and right virtual lines ILL and ILR that extend from the side to the front of a vehicle along the partitioning lines OL and BL, controls the steering so the vehicle travels between the left and right virtual lines ILL and ILR, moves the left virtual line ILL to a position in proximity to the road edge E and fixes the left virtual line ILL to this position, and then, moves the right virtual line ILR to a position separated from the left virtual line ILL by the width of the vehicle and fixes the right virtual line ILR to this position, and controls brakes to stop the vehicle after fixing the left and right virtual lines ILL and ILR.

Abstract: A steering device comprises a tilt-telescopic mechanism to switch between its tilt-and-axial move allowed state and its prohibited state. The tilt-telescopic mechanism comprises a pair of side wall portions provided on both sides, in a vehicle width direction, of an upper column, a bolt penetrating the side wall portions and pressing the side wall portions against each other in an approaching direction, a lever, and a biasing portion arranged between each of the side wall portions and the upper column and operative to apply a pressing force to the upper column from the both sides, in the vehicle width direction, thereof. The biasing portion comprises a pair of upper-side pressing portions to press an upper portion of the upper column above its axial center from both sides and a pair of lower-side pressing portions to press a lower portion of that below its axial center from both sides.
