    Abstract: A multi-stage helical gear manufacturing apparatus includes a first mold member, a second mold member, a large gear rotation core, a sleeve pin, a small gear rotation insert, and an insert pin. The second mold member moves the insert pin and the small gear rotation insert after the insert pin is caused to retreat in relation to the small gear rotation insert at the time of mold opening. The first mold member prohibits rotation of the large gear rotation core at the time of mold clamping, permits rotation of the large gear rotation core when the insert pin and the small gear rotation insert of the second mold member are moved at the time of mold opening, and causes the sleeve pin to advance toward the second mold member in relation to the plastic after the insert pin and the small gear rotation insert are separated from the plastic.

    Abstract: The present specification provides a technique for accelerating solidification of a liquid gasket. A cooler disclosed herein comprises a main body, a cover, a pair of first fins, and second fins. A channel through which refrigerant flows is formed in the main body. The cover is attached to the main body to close the channel with a liquid gasket. The first fins are arranged on the main body or the cover, and each of the first fins extends along a refrigerant flow direction and facing corresponding one of inner side surfaces of the channel. The second fins are arranged between the pair of first fins. A height of the first fins is smaller than a height of the second fins. The first fins having the smaller height allows larger amount of the refrigerant flowing by the liquid gasket, and thus the liquid gasket efficiently absorbs water and quickly solidified.
