Abstract: A control unit performs a lane departure suppression control when a host vehicle is about to depart from a traveling lane. The control unit determines whether a low impact collision has occurred. The control unit performs a secondary collision damage mitigation control when the low impact collision is determined to have occurred while the lane departure suppression control is being performed.

Abstract: A method of producing a sealing member for a fuel cell includes: setting a base material made of a modified polypropylene in a mold; bringing a hydrosilicone crosslinked ethylene/?-olefin/non-conjugated diene copolymer into contact with the base material and performing molding in the mold; and vulcanizing the hydrosilicone crosslinked ethylene/?-olefin/non-conjugated diene copolymer and at the same time, bonding the hydrosilicone crosslinked ethylene/?-olefin/non-conjugated diene copolymer and the base material by vulcanization, in the mold with a molding temperature set to a temperature that is higher than a vulcanization start temperature of the hydrosilicone crosslinked ethylene/?-olefin/non-conjugated diene copolymer and lower than a melting point of the modified polypropylene.

Abstract: A smaller cylindrical portion having a clamp groove formed on an outer peripheral surface thereof has a cylindrical surface portion which extends straight in an axial direction, an inclined surface portion which extends, while being inclined, radially outwardly from an end portion of the cylindrical surface portion and a vertical wall surface portion which extends straight radially outwardly from an end portion of the inclined surface portion, the cylindrical surface portion, the inclined surface portion and the vertical wall surface portion being formed continuously sequentially in that order from a side wall surface of the clamp groove. A stress concentration on a specific location on the smaller cylindrical portion can be suppressed by virtue of the stress alleviating action of these cylindrical surface portion, the inclined surface portion and the vertical wall surface portion.

Abstract: Tools are classified into small type tools that can pass through the space between a pair of grippers in its open position and large type tools that cannot pass through the space between the pair of grippers in the open position, when the headstock supporting a spindle holding a tool is moved to a position corresponding to a tool change position. When the next tool to be used is of the small type, the tool is moved through a standby position to the tool change position during a machining operation using the tool on the spindle, the headstock is moved to the position corresponding to the tool change position in response to a tool changing instruction and a predetermined tool changing operation is carried out.

Abstract: A tool magazine disclosed is fundamentally the same in construction as a corresponding prior art tool magazine but is capable of handling tools of diameters greater than those of tools which can be handled by the prior art tool magazine. The tool magazine comprise a magazine body provided with an endless guide groove, and a plurality of tool pots each for holding a tool, fixedly provided with guide members engaging the endless guide groove for sliding movement along the guide groove. Idlers are disposed between and in contact with adjacent tool pots, respectively, and supported in the endless guide groove so as to move along the endless guide groove. A feed mechanism moves the tool pots and the idlers along the endless guide groove with the idlers in contact with the guide members of the adjacent tool pots, respectively. The idlers are substantially the same in shape and dimensions as the guide members.

Abstract: A toolholder device for a machine tool comprises a holder body driven by a machine tool drive spindle, and a toolholder supported on the holder body so as to be circumferentially and axially displaceable. The holder body and the toolholder are provided with displacement detection elements which are arranged circumferentially in interdigitating relation. A support shaft extends from either member of the holder body and the toolholder toward the other member. The outer surface of the support shaft and the inner surface of a support hole of the other member to be fitted over the support shaft are formed with helical guide grooves which are opposite to each other and slopingly extends with respect to the rotational axis of the toolholder device.

Abstract: A toolholder assembly is divided into a drive toolholder coupled to the drive spindle of a machine tool, and a driven toolholder carrying a cutting tool such as a drill. The driven toolholder is coupled end to end to a drive toolholder so as to be rotatable relative to the same through a preassigned angle about the toolholder axis. A coiled torsion spring acts between the drive and the driven toolholders for torque transmission from the former to the latter. The drive and the driven toolholders have interdigitating teeth with clearances therebetween. A phase detector such as a proximity switch detects a relative phase displacement that will occur between the interdigitating teeth against the force of the torsion spring upon development of abnormal torque load on the cutting tool.

Abstract: An indexing apparatus for a rotary table has a support shaft rotatably supported by a base member in which indexed terminal positions of the rotary table is determined by abutment of a stopper member provided on the rotary table against positioning members provided on the base member. The indexing apparatus comprises a rack-pinion mechanism comprising a rack and a pinion fixed around the support shaft of the rotary table for rotating the same, a feed screw shaft rotatably supported by the base member and extending along the rack in a direction of the movement thereof, a breakable electric motor for driving the feed screw shaft, and a feed nut engaging the feed screw shaft. The rack and the feed nut are arranged so that either one of them has integral portions disposed at both sides of the other with spaces left on both the sides in the direction of the movement of the rack. Annular springs are disposed in each space.
