摘要:
An outer panel is made thinner than an inner panel, and a rear face facing a front door is folded so as to form a valley groove hollowed toward the interior of a tube constituted by true outer panel and the inner panel, whereby when a large magnitude of external force is applied to a front face in a rear ward direction, the outer panel is allowed to be deformed more largely than the inner panel to thereby collapse the valley groove, whereby the rearward travel of the rear face can be reduced.

An automotive vehicle in which a door hinge 64 of a front door 15 can forcibly be moved transversely outwardly of the vehicle, the automotive vehicle comprising an acceleration sensor 57 for detecting an impact applied to a front pillar and a door moving mechanism 52 for forcibly moving the door hinge 64 transversely outwardly of the vehicle, whereby the front door 15 is constructed to be moved transversely outwardly of the vehicle. In the event that an impact is applied to a front pillar, a front door can forcibly be moved transversely outwardly of an automotive vehicle on a side where the door hinge is provided, and in a case where the hinge is disposed in the vicinity of the front pillar, the transversely outward movement of the front door can be made large, whereby the interference of the front pillar with the front door can positively be prevented. Consequently, since the deformation of the front pillar cannot be prevented, the impact applied to the front pillar can effectively be absorbed and reduced.

A pillar outer of a front pillar of an automotive vehicle comprises a stiffener and a flange portion connecting to a pillar inner. A peripheral portion of a windshield is fixed to a front face (a face orienting outwardly of the vehicle) of the flange portion via a plastically deformable member which can be deformed easily and plastically when a load is applied thereto in a longitudinal direction of the vehicle body. When an impact generated when an obstacle comes to interfere with the windshield is transmitted to the plastically deformable member, the plastically deformable member is easily press collapsed by the load, and the impact that is to be received by the windshield and the obstacle can be absorbed through the impact absorbing action. In addition, since the front face of the peripheral portion of the windshield is disposed flush with an outer wall portion of the pillar outer, a connecting portion between the two members is made flush with those members to thereby reduce the air drag thereat.

A simple process for producing v-coelenterazine compounds has been desired. Described is a process for producing a v-coelenterazine compound represented by general formula (II) comprising (1) the step of reacting a compound of general formula (VIII) with a methyltriphenylphosphonium salt in the presence of a base to give a compound represented by general formula (IX), (2) the step of performing a ring-closing metathesis reaction on any one selected from the group consisting of the compound represented by general formula (IX) and a compound of general formula (X) which is the compound of general formula (IX) wherein the amino is protected with R5, and then deprotecting R4 and, if any, R5 to give a v-coelenteramine compound represented by general formula (XIV), and (3) the step of reacting the compound of general formula (XIV) with a compound represented by general formula (XV) to give the compound of general formula (II).

To readily remove on-vehicle components from a vehicle body, suitably reflecting the state of the vehicle or occupant in addition to the will of the operator.The safety confirmation device 11 determines whether or not to permit actuation of the separation actuator 13, that is, whether to set the switch 12 to the ON state to allow an electrical connection from the power supply 14 to the separation actuator 13, based on the signals input from the external input receiving portion 21, the occupant protection device 22, the status quantity sensor 23, and the input portion 24, and outputs a gate signal corresponding to this determination result to the switch 12. Electrification of the separation actuator 13 from the power supply 14 via the switch 12 releases the fixation of an on-vehicle component by disassembling the fixation member that fixes the on-vehicle component to the vehicle body.
