Title: Formation of spiral tungsten heater and its device
Inventor: NAKAJIMA TOSHIAKI
IPC: H05B3/76
Filed: 1988-04-13
Abstract: PURPOSE:To make it possible to form a spiral flat and at a constant pitch by winding a tungsten linear material spirally between a pair of pins provided protruding in the center of a rotary disc while winding a spacer linear material by rotation of the disc. CONSTITUTION:A tungsten linear material (a) is put on a rotary disc 6 to be held between a pair of protruding pins 7, 7 at its center part. Both of its ends are positioned in a guide passage 12 at a flange part 10, and a spacer liner material (b) pulled from spacer linear material supply ports 8, 8 for a similar length to that of the tungsten linear material (a) is applied to the side of the tungsten linear material (a), then a rotary shaft 2 is rotated by means of a lever 3 while the disc 6 is pushed by a presser plate 13. The protruding pins 7, 7 thus bend and wind the tungsten linear material (a) into a spiral, while spiral winding of the linear material (a) also winds the spacer linear material (b) between its pitches simultaneously. The linear material can thus be wound to be a flat spiral from the initial stage on, keeping its winding pitch constant.

Title: Finned-tube type heat exchanger
Inventor: KASE HIROAKI
IPC: F28F9/26
Filed: 1987-04-13
Abstract: PURPOSE:To improve the heat exchanging performance by inserting both ends of a U-bend into heat transmission pipes to a position that overlaps some fins. CONSTITUTION:At the time of connecting a U-bend 14 to heat transmission pipes 13, the ends of the U-bend 14 are contracted to allow their insertion into the heat transmission pipes 13. The ends of the U-bend 14 are inserted deeper than the end plate 15, i.e. up to a position that overlaps the fin 12. By impregnating the brazing material 16 to the ends of the U-bend 14 at the time of brazing, the pressure resistance strength of the part of the heat transmission pipes 13 extending beyond the end plate 15 can be made larger. As a result, a water pressure high enough can be applied to a heat exchanger having a curved finned- tube, and the curved part of the heat transmission pipes 13 can be made tightly in contact with the fins 12, which improves the heat exchanging performance.
