Abstract: To provide a food storage container capable of preventing penetration of blood and juice and there is almost no level difference in the four corners not to generate air space even when a top seal is applied.

Abstract: A working vehicle includes a vehicle main body to which a tire is mounted, an excavation member coupled to the vehicle main body on a front side of the vehicle main body and that includes an end part arranged on an outer side of the tire in a vehicle-width direction of the vehicle main body, a hydraulic cylinder arranged at a center part in the vehicle-width direction and that is to move the excavation member, a housing that houses a power transmission mechanism to transmit power to the tire, and a camera supported by a part of the vehicle main body on a lower side of the hydraulic cylinder and on an upper side of the housing and that acquires an image of a region that includes end parts on both sides of the excavation member and that is between the excavation member and the tire.

Abstract: A solder ball is formed from an Sn—Pb alloy which consists essentially of about 2–65 mass % of Sn, 0–5 mass % of Ag, about 0.1–1 mass % of Sb, and 0.01–0.1 mass % of Cu, and 0.01–0.1 mass % of Bi, and a balance of Pb and incidental impurities. The solder ball has improved thermal fatigue resistance, good solderability, and good surface brightness after soldering.
