Abstract: There is provided a target installation apparatus. A rod-shaped member is capable of being arranged to extend in a vehicle width direction of the vehicle ahead of or behind the vehicle, and is provided with a target point indicating an installation position of the target. A reference member is formed such that reference points are positioned on left and right outer sides in the vehicle width direction of the vehicle when the reference member is arranged with respect to the vehicle. A connection unit connects the rod-shaped member and the reference member such that a distance from the reference point to the target point in the front-and-rear direction satisfies a predetermined condition.

Abstract: A coating composition comprising (A) a thermoplastic resin having a glass transition temperature of 0.degree. to 80.degree. C., (B) a compound having 2 or more hydroxyl groups in the molecule, (C) a thixotropic agent and (D) a solvent, and said coating composition having a viscosity of 3 to 50 poises at 25.degree. C. and a thixotropy of 2 or more can give a moistureproof insulating coating film with uniform and large thickness and very few bubbles by one-time treatment over packing circuit boards.

Abstract: A resinous composition comprising (a) a low-odor crosslinkable monomer obtained by reacting a glycidyl ester of synthetic or vegetable oil fatty acid with acrylic acid or methacrylic acid with heating, and (b) a polybutadiene modified by acrylic acid or methacrylic acid or an unsaturated polyester resin produces almost no or very little odor in the state of a varnish and at drying or curing. Said composition can produce varnishes excellent in mechanical and electrical properties.

Abstract: An unsaturated polyester resinous composition comprising (a) unsaturated polyester, (b) a crosslinkable monomer, (c) at least one compound selected from the group consisting of 1,2,4-triazole and its derivatives, (d) a curing agent and (e) a manganese salt of organic acid as a curing accelerator is excellent in the adhesion to copper, the prevention of patina, air drying characteristics and stability of varnish.
