Abstract: A joined article including: a resin (1) having a linear expansion coefficient at 30° C. to 200° C. of 17 ppm/° C. or higher and a thickness of 5 to 100 ?m; and a metal joined to a surface of the resin (1) and having a thickness of 5 to 50 ?m. The resin (1) includes a heat-affected layer that is close to the metal and that occupies 80% or less of the thickness of the resin (1), and the joined article is a dielectric material for a substrate. Also disclosed is a substrate including the joined article and a resin (2) stacked on the joined article.

Abstract: A refrigeration apparatus for a transport container has a partition to divide the interior of a box, which is mounted on the front wall of a container, into two compartments. In one of the compartments is disposed a refrigeration assembly including an evaporator, an evaporator fan, a condenser, a condenser fan and a refrigerant compressor, on the other hand, in the other one of the compartment is disposed a common mount on which a generator assembly including an engine, an engine radiator, a radiator fan and a generator in in-line relation is mounted in such a manner that the generator assembly may be installed into or removed from the box as one unit. The refrigeration assembly and the generator assembly are thermally isolated from each other by the partition, so that an exhausted warm air from one assembly does not heat the other assembly.

Abstract: A refrigeration unit comprising a cooling circuit having a compressor, a condenser and an evaporator, and said unit including a hot gas valve and a hot gas bypass passage bypassing the condenser and forming a defrost circuit, so that when the evaporator is frosted upon operation by means of the cooling circuit, constant quantity refrigerant is circulated around the defrost circuit to perform a defrosting operation.
