Abstract: A meat roaster capable of preventing meat from burning and sticking to a grill is provided. The meat roaster includes a body having an accommodating portion for accommodating a heat source. A grill connected to the body includes a frame and a fluid circulating pipe. The pipe is mounted at one side of the frame in such manner that the pipe is repeatedly bent at regular intervals. The pipe has an inlet socket formed at one end of the pipe and an outlet socket at the other end of the pipe. A temperature controller controls a fluid circulating through the pipe of the grill at a predetermined temperature which prevents the grill from overheating.

Abstract: An improved reel spring structure for rotatably supporting tape reel shafts of video tape cassette, the spring comprising an elongated strip of resilient material having a flat, central portion having a pair of holes symmetrically formed therein, first inclined portions symmetrically, slopingly provided at the opposite ends of the central portion and each having a rectangular, embossed groove, second inclined portions symmetrically, slopingly provided at the outer ends of the first inclined portions, and rounded tip portions symmetrically provided at the opposite distal ends of the spring to be continued from the second inclined portions, whereby the desired tension on the tape reel shafts can be maintained by a spring having a minimal width.
