Abstract: The present invention aims at providing a circular waveguide polarizer with high performance and low cost.      The circular waveguide polarizer is realized by arranging a plurality of side grooves 12 in a side wall of a circular waveguide 11 along the direction of a pipe axis C1 and by appropriately designing the number, spacing, radial depth, circumferential width, length in the pipe axis direction, and the like. According to this circular waveguide polarizer, disturbance is imparted to a section with a coarse electromagnetic field distribution in a transmission mode to create a phase delay, so that the amount of phase delay does not vary largely with a delicate change in width, depth and length of the side grooves 12. That is, there is little deterioration in characteristics caused by a machining error or the like, and hence it becomes possible to effect mass production and cost reductions.

Abstract: An apparatus and method for automatically producing a desired specific gravity of a salt solution used for deicing highways. Highway departments can produce a high volume of salt solution of a desired specific gravity by a machine that automatically feeds salt and water into a hopper tank to produce brine, then automatically measures and adjusts the specific gravity of the brine by adding greater or lesser amounts of fresh water to the brine removed from the hopper tank. The salt added to the hopper tank contains impurities, which are removed by self-cleaning strainers. The sediment so removed flows to a trash tank. Sediment in the trash tank settles to the bottom thereof and the liquid collected is filtered by another set of self-cleaning strainers such that liquid from the trash tank can be sent to the hopper tank. The device automatically records the specific gravity of the solution produced.
