Title: Boiler superheater
Inventor: NAKAO MOTOFUMI
IPC: F22B37/10
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a boiler superheater that is inexpensive, cannot be damaged greatly by alkali corrosion, and has a long life. SOLUTION: A cylindrical pipe 20 is arranged inside the steam inlet side of a superheater pipe 5a made of carbon steel. Since the inner surface temperature of the cylindrical pipe 20 is more uniform than the inner surface temperature of the superheater pipe 5a, the mist of the boiler water being carried over from the inlet header 13a is evaporated uniformly in the cylindrical pipe 20. As a result, even if an alkaline constituent is contained in the mist, the distribution of deposited alkali becomes uniform on the inner surface of the cylindrical pipe 20 and cannot be concentrated at a specific location. Therefore, a corrosion speed become relatively slow and the life of the cylindrical pipe 20, namely a superheater 5, can be extended.  In this case, by forming the cylindrical pipe 20 with a wire netting or a lath plate or an iron group or Ni group alloy with 9% or more Cr, the life can be extended further.

Filed: 1981-02-19
Abstract: PURPOSE:To flatten the frequency of an electrodynamic speaker up to a high range, by achieving two-point driving by fixing voice coils to one nodal point of oscillation mode and another nodal point. CONSTITUTION:A voice coil 3 is fixed at one node b4 of oscillation mode B with resonance frequency f3, and a voice coil 3' is fixed at another node b3 to drive a diaphragm 1 at two points. With regard to two-node driving of mode B, nodes b3 and b4 are considered to be driven equivalently by driving forces F1 and F2, and the driving points by the F1 and F2 are nearly symmetric on one node a2 driving mode A. Therefore, this driving provides the same effect with the nodal driving of the node a2 of mode A by a voice coil bobbin 12 having a diameter x1+x2. Thus, the coils 3 and 3' perform nodal driving of mode B at a frequency f3, and consequently the attenuation of the frequency f3 is performed completely. Therefore, sound pressure frequency characteristics are flattened.
