Filed: 1988-12-28
Abstract: PURPOSE:To make it possible to effect good cooking without uneven roasting on both faces of a food to be cooked by igniting an upper section gas burner firstly and a lower section gas burner next and starting air blast delivery from a blower after the flame covers the whole flame jet openings of the lower section gas burner. CONSTITUTION:Approximately in the central section between the upper and lower sections of a heating chamber 1 an object to be cooked 2 is placed. In the chamber 1 a roasting net 3 for roasting foods, upper gas burner 4 above the roasting net and lower gas burners 5 on both sides of the heating chamber below the roasting net are provided. Blowers 6 are provided near the lower gas burners. The air blast volume is controlled by duty control which turns the blowers ON and OFF. With this constitution the steam of combustion by the lower gas burners is pushed to the central section of the heating chamber by the air blown out from the blowers or drawn out so that the heat distribution is uniform even in a heating chamber which is large in width and uniform roasting of foods on their both faces can be given. Further, since the upper burner is first ignited and then the lower gas burner is ignited and, when all the flame jet openings are in flame, the air blast is started, there is no effect of wind when the flame propagates to all the flame jet openings after the ignition, making it sure that all the flame jet openings are in flame and the generation of raw gas is suppressed.

Title: Forming mold of optical reflecting mirror
Inventor: SUGA TETSUO
IPC: B29L11/00
Filed: 1989-12-22
Abstract: PURPOSE:To uniformly cool the whole molded item and consequently prevent strain from developing and obtain highly accurate planeness by a method wherein a mold opposite to a mold, by which mirror surface is produced, is formed so as to produce a cavity, which becomes gradually larger outwards from its central part. CONSTITUTION:A fixed mold 6 consists of a tubular fixed retainer plate 7 and a fixed core 8. A movable mold 9 consists of a tubular movable retainer plate 10 and a movable core 11. A cavity 13 is formed between the fixed core 8 and the movable core 11. The cavity surface 8a of the fixed mold 8 is mirror-finished so as to produce optical reflecting mirror surface by reversal. On one hand, the cavity surface 11a of the movable core 11 is matt- finished and made to be convex. Molten resin is filled in the cavity 13 so as to be formed under the condition that no dwell pressure is applied. During the cooling of the resin, the shrinkage of the resin develops on the cavity surface 11a (matte surface) side, resulting in developing the separation between the resin and the cavity surface 11a, while no separation develops between the resin and the cavity surface 8a, since the adherence between the resin and the cavity surface 8a is strong. Thus, in the obtained molded item, its wall thickness is gradually thicker outwards from its central part so as to be uniformly cooled, resulting in obtaining highly accurate planeness. Further, when the mirror surface consists of a plurality of faces, the cavity surface consists of a plurality of faces.
