A clothes dryer capable of providing a dry course suitable for functional clothes, and a control method thereof, the control method including if a substance accommodated in a dry tub to be dried is functional clothes, performing a first dry process to dry the substance at a first reference dry temperature, and performing a second dry process to dry the substance at a second reference dry temperature higher than the first reference dry temperature.

Provided is a cap-type vent having a porous waterproof air-permeable sheet inserted and mounted in a cap housing having fixing ribs formed therein, and fixing the waterproof air-permeable sheet by a supporting member made from an elastic material. The provided cap-type vent comprises: the supporting member of which one end is coupled to an object to be applied; the waterproof air-permeable sheet positioned at the other end of the supporting member; and the cap housing formed in a cup shape having an opening formed at one end thereof, into which the supporting member and the waterproof air-permeable sheet are inserted through the opening, wherein the supporting member has an air circulation hole formed by penetrating the supporting member, and the fixing ribs coming in contact with the outer lateral wall of the supporting member so as to fix the supporting member and formed on the inner lateral surface of the cap housing.

The invention belongs to the technical field of installation of nuclear power plant equipment. In order to successfully complete the installation of an elastic connecting piece of an equipment gate and ensure the successful construction progress of an entire safety shell, the invention discloses a method of installing the elastic connecting pipe of the gate of nuclear power plant equipment. The installation method comprises the following steps: step 1. axially compressing and fixing the elastic connecting piece; and step 2. introducing the elastic connecting piece and completing the connectionand fixation between the elastic connecting piece and an outer casing penetration shell ring after completing the installation of the outer casing penetration shell ring and before carrying out the inner casing prestressing force operation; step 3. temporarily connecting an inner casing side body in the elastic connecting piece to an outer safety shell in a suspension manner; step 4. carrying outinner safety shell prestressing force treatment; and step 5. connecting and fixing the inner casing side body in the elastic connecting piece to an inner casing pre-embedded ring plate in the elasticconnecting piece. The method can successfully complete the installation of the elastic connecting piece and ensures the successful construction progress.

The present invention relates to a cooling device (1) comprising a body (2) having a rear wall (3) having an inner surface (4), an outer surface (5) produced from cellulosic material and an insulation material (6) filled in the volume between the inner surface (4) and the outer surface (5), and wherein the insulation material (6) is prevented from forming deformations on the outer surface (5) during its solidification.

The invention discloses a composite structure reinforcing steel bar connecting node, which solves the problems that the working procedures of composite structure reinforcing steel bar connection in construction industry are large in task load, high in execution difficulty and long in required time. The composite structure reinforcing steel bar connecting node at least comprises a structural column body and a reinforcing steel bar connector arranged on the outer surface of the structural column body. The structural column body is a circular pipe column or a cross steel rib column or a steel rib column shaped like a Chinese character 'Wang' or an H-type steel rib column. A plurality of annular plates are arranged inside the circular pipe column, and a plurality of groups of rib plates are further arranged; each group of rib plates is corresponding to a group of vertical plates on the periphery of the circular pipe column, the outer ends of each group of vertical plates are connected with vertical plate end plates; and a reinforcing steel bar connector is arranged on the vertical plate end plate. The reinforcing steel bar connectors, the annular plates and the wall of the steel rib column are welded, and a complete force system is formed by the rib plates at corresponding positions in the steel rib column, so that reinforcing steel bars in a concrete beam can transmit the power into the structural column through the system so as to achieve the effect of reinforcing steel bar anchoring or penetrating. The system has the advantages of being convenient and fast for construction, reliable for quality, high in economic level and industrialization process, and the like.

The invention discloses manufacturing equipment and method of a long screw rod. The equipment comprises a rear supporting frame, a mold body, a threaded wire and a front bracket. The equipment is characterized that the two ends of the mold body penetrate through the rear supporting frame and a front supporting frame correspondingly and the mold body can auto rotate, and a thread line is positionedin the inner portion of the mold body and penetrates through the inner surface of a cavity of the axis of the circle center.
