IPC: H01Q13/02
Filed: 1991-01-23
Abstract: PURPOSE:To use a scalar feed horn in a wide frequency band by providing concentric circular chokes in specified angle areas with respect to the direction of respective linearly polarized waves as against respective linearly polarized waves to which two frequencies are orthogonally linearlly polarized wave-fed and setting the radiation patterns of respective frequencies to be satisfactory patterns symmetric as against an axis. CONSTITUTION:The scalar feed horn has a horn which is formed by a circular waveguide 3 and the concentric circular chokes 2a and 2b suppressing a backward current at the external side of the opening surface 1. Then, the scalar feed horn common to the two frequencies of the orthogonally linearly polarized wave, in which the electromagnetic wave of a first frequency is fed by a vertically polarized wave, and the electromagnetic wave of a second frequency is fed by a horizontally polarized wave, is formed. Here, the first concentric circular choke suppressing the backward current in the first frequency in the angle of + or -45 deg. as against the direction of the electromagnetic wave fed by the first frequency and the choke suppressing the backward current in the second frequency is given to the angle area of + or -45 deg. as against the direction of the polarized wave of the electromagnetic wave fed by the second frequency.

Title: Biological treatment of waste water
Inventor: KATAOKA KATSUYUKI
IPC: C02F3/06
Filed: 1980-01-22
Abstract: PURPOSE: To facilitate the biological treatment of waste under a stable condition for a long time while saving an aeration amount to a packed layer, by providing a solid grain packed layer floating in water and containing bacteria, feeding waste water downward through the packed layer, and intermittently supplying an O 2 -containing gas from the lower part through the packed layer.  
     CONSTITUTION: An O 2 -containing gas 4, e.g. air is intermittently supplied from a gas supplier 5 through a packed layer 7, while untreated water 2 flows downward through the packed layer 7. As a result, bacteria films grow on the surfaces of solid grains forming the layer 7, within a few days. The bacteria films reduce the BOD value of the untreated water, and nitrify the ammonia nitrogen in the water. Thus, the untreated water is biologically treated during passing through the layer 7, and discharged 3 outside the system. The layer 7 acts as a stable bed floating on the upper part of the disposer 1 due to its own buoyancy and an arresting power of a floating arrestor 8, so that the layer 7 is not disturbed when the air bubbles from the supplier 5 penetrate into the layer 7. Consequently, the air bubbles flow upward through the layer 7, while repeating catches and stays in the cavities of the layer 7.

Filed: 1981-01-19
Abstract: PURPOSE:To prevent overrun of a travelling object at the position of more than one rotation by stopping it through the counting detection signals of detection elements so arranged thereon to be sensitive to permanent magnets buried along a loop track. CONSTITUTION:Permanent magnets 3 and 4 are buried along a loop track 1 and detection elements 5 and 6 are so arranged on a travelling object 1 as to be sensitive to the permanent magnets 3 and 4. When a rotary direction command switch 13 is operated to the normal position, a command signal 31 moves to ''H''. The travelling object 2 rotates normally passing the permanent magnet 3 and returns to the permanent magnet 3 after one rotation. Each time the detection element 5 detects the permanent magnet 3, the detection signal 32 is output. When counting the detection signal 32 upto two, a counting circuit 18 opens a switch 14 to stop the travelling object 2. To reverse the rotation, detection signals 36 of the detection element 6 are counted with a counting circuit 21.
