Abstract: A method for producing isobutyl vinyl ether using isobutyl alcohol as a raw material alcohol, the method including reacting the isobutyl alcohol with acetylene to obtain a mixture containing unreacted isobutyl alcohol and isobutyl vinyl ether, reacting the unreacted isobutyl alcohol and the isobutyl vinyl ether in the mixture in a presence of an acid catalyst to be converted into acetaldehyde diisobutyl acetal, and removing the acetaldehyde diisobutyl acetal by distillation.

Abstract: An impact absorbing structure absorbs an impact applied from outside or inside of a vehicle near a seat belt anchor bolt that protrudes from the vehicle body panel toward the inside of the vehicle. The impact absorbing structure includes a cylinder body that accommodates a head part of the seat belt anchor bolt; an impact absorbing box arranged adjacently to the cylinder body, the impact absorbing box including a top plate facing the vehicle body panel; a base that supports the impact absorbing box; an attaching unit that attaches the base to a back face of the vehicle interior component; a stepped portion arranged on a side face of the impact absorbing box as a base point of crush deformation of the impact absorbing box; and a rib arranged between the impact absorbing box and the cylinder body to prevent escape of the impact absorbing box due to tilting thereof.

Abstract: To allow short time spreading for adhesive, verifying whether the adhesive is spread out to a member end. In obtaining a bonded member by applying the adhesive to a surface of one of two members and bonding the members with a member bonding device, a tilt adjusting device acquires with a camera an image of spreading state of the adhesive in the members' bonding surface, and adjusts the tilt of the bonded member when a non-spreading part of the adhesive between ends of the bonded member and the adhesive has a size bias so that the adhesive moves to the larger side of the part, and a spreading adjustment device controls a pushing amount and a pushing time interval of a pressing-side member to adjust spreading of the adhesive so that the part size reduces to a predetermined size depending on the part size acquired with the camera, and cures the adhesive in the bonded member edge with the non-spreading part eliminated.
