Title: Circularly polarized wave generator
Inventor: ARIYOSHI KOTA
IPC: H01P1/17
Filed: 1989-03-31
Abstract: PURPOSE:To obtain a circularly polarized wave generator with simple constitution and with superior characteristics by installing two phase shifters where one of two orthogonal polarized waves is matched and the phase difference of both polarized waves comes to be 45 deg. in a waveguide and setting the distance of both phase shifters in such a way that the other polarized wave can be matched. CONSTITUTION:When dielectric boards 6 and 6' which are almost hexagonal are inserted in a plane including AA' of the waveguide and a waveguide axis as the phase shifters where the reflective coefficient of the polarized wave B is small and the phase shift amounts of the polarized wave A and the polarized wave B come to 45 deg., they come to the phase shifters where the reflection of the polarized wave B is small and the whole phase shift amount comes to 90 deg.. At that time, the size of the reflection of the polarized wave A changes in accordance with the interval (d) of two dielectric boards 6 and 6'. When the interval (d) is adjust in such a way that the reflected wave of the polarized wave A by the dielectric board 6 on an input-side and the reflected wave of the polarized wave A by the dielectric board 6' at the back of the board 6 are mutually compensated, reflection with respect to the polarized wave A becomes considerably small. Thus, the phase difference of the polarized wave A and the polarized wave B comes to 90 deg. in an output terminal, the sizes of transmission coefficients in both come to a value near '1', whereby the amplitude of the polarized waves A and B becomes equal.

Title: Method of burning low nox fine powder coal and burner for igniting fine powder coal
Inventor: NARATO KIYOSHI
IPC: F23D1/00
Filed: 1988-04-06
Abstract: PURPOSE:To reduce NOx by a method wherein mixture gas is injected from a fine powder coal nozzle with a primary air for use in feeding fine powder coal and ignited, thereby its injection is kept by restricting a mixing of secondary air and third air at a distance more than an inner diameter size of an injection port of the fine powder coal nozzle. CONSTITUTION:An enlarged sectional part is arranged at an extremity end of a fine powder coal nozzle 2, a mixture air flow of fine powder coal and primary air is guided to the enlarged sectional part, a flow speed of the mixture gas is reduced and at the same time an outside secondary air flow speed is increased. A stream line having an enlarged mixture flow gas is reduced at a reduced sectional part acting as a flame holding ring 9 at an extremity end of the fine powder coal nozzle 2 and then injected. Since the fine powder coal in the mixture gas flow has an inertia force, the fine powder coal may easily be concentrated at a central part of the nozzle at the enlarged sectional part. In addition, the larger the size of the particles, the larger the inertia force, so that the particles are concentrated at the central part. Due to this fact, a flow of fine powder coal 16 having a high concentration is formed at a down-stream side of the flame holding ring 9 at the extremity end of the nozzle, resulting in an area having a low concentration of O2 being formed at a central part of the flame, NOx is reduced thereby concentration of NOx is decreased.
