Abstract: A vehicle-body front structure includes a rectangular bulkhead that supports a radiator that is provided in a front part of a vehicle body. The bulkhead includes a pair of bulkhead side members arranged at both sides of the bulkhead and extending in a vehicle up-down direction, and a bulkhead lower member arranged at lower ends of the bulkhead side members and extending in a vehicle width direction. The bulkhead lower member has a smaller length than a distance between the pair of bulkhead side members. The bulkhead lower member includes a pair of extensions being respectively hung between the bulkhead lower member and the bulkhead side members in the vehicle width direction. The bulkhead lower member is joined to inner sides of the pair of extensions such that the extensions are hung in a vehicle front-rear direction.

Abstract: A vehicular reinforcing bar structure includes: a reinforcing bar fixedly fastened at its opposite end portions to a pair of opposed vehicle body frame members, the reinforcing bar having a uniform closed sectional shape from one of the end portions to the other; collars fitted in the respective opposite end portions of the reinforcing bar for imparting fastening force to the end portions; and mounting brackets provided in corresponding relation to the opposite end portions, each of the mounting brackets being formed in a closed section and fixedly fastening the corresponding end portion by sandwiching the end portion with the corresponding vehicle body frame member.

Abstract: A heating vessel for concentration is formed in an elongated one, and a baffle plate is arranged to increase sulfuric acid liquid concentration at an outlet to a high level. The heating vessel for concentration and a heating vessel for distillation are installed so that the respective heating vessels have substantially the same waste sulfuric acid liquid level therein, forming continuous flow of the sulfuric acid liquid without presence of a valve or an intermediate tank in a connecting pipe. The heating vessel for distillation is formed in an elongated one with a baffle plate arranged therein to increase the impurity concentration included in concentrated sulfuric acid liquid at an outlet to a high level.
