摘要： PROBLEM TO BE SOLVED: To provide a rotary joint with a simple configuration and a small loss even at a high frequency. SOLUTION: This rotary joint 1 has 1st-3rd members 2, 4, 6. The 1st member 2 is formed to be a disk. The 2nd member has a recessed part 8 open to one side. The 1st member 2 covers the recessed part 8 to form a cavity. The center axis of the 1st member 2 passes through the inside of the cavity. The 3rd member 6 clamps the 2nd member 4 in cooperation with the 1st member 2 so that the 2nd member 4 is turnably around the center axis. A bolt connects the 1st member 2 and the 3rd member 6 attachably and detachably. A probe 30 is fitted to the 1st member 2. The probe 30 is intruded into the cavity through the center axis from the 1st member 2. A probe 34 is fitted to the 2nd member 4. The probe 34 is intruded in the cavity in parallel with the probe 30 from the 2nd member 4.

摘要： PROBLEM TO BE SOLVED: To provide a beam switching antenna with which an inertia moment is reduced by miniaturizing a rotary part itself, high-speed rotation sufficiently satisfying a scan speed is enabled and an insertion loss is reduced. SOLUTION: This antenna has a microstrip circuit board 1 circumferentially arranging plural patch antenna radiation elements 11 and a turnable microstrip power feeding line 21. Then, the power feeding line 21 is turned and successively overlapped with the patch antenna radiation elements 11, and the turnable microstrip power feeding line 21 to be slot-connected has a rotary shaft 5 at a position having a fixed gap from the patch antenna radiation element 11 and is slot-connected with a microstrip power feeding line 41 for input at the position of the rotary shaft 5.

摘要： PROBLEM TO BE SOLVED: To connect an antenna with the inner circuit of a communication equipment through a waveguide by providing a locking mechanism for locking a rotor at a prescribed rotary angle, forming through holes matching the diameter of the waveguides for the rotor and a fixed stand, matching the through holes of the rotor and the fixed stand in a state where the rotor is locked at the prescribed rotary angle, to make a part of the waveguide. SOLUTION: The locking mechanism 800 locking the rotor 400 at a prescribed rotary angle position is provided for one sideboard part 550A of the fixed stand 500. The rotation side through hole 420 of the rotor 400 and the fixed side through hole 560 of the fixed stand 500 are linearly connected. The waveguide of the antenna and the waveguide in a casing are connected through the waveguide constituted of the rotor 400 and the fixed stand 500. When the antenna becomes in a state where it inclines by >= a prescribed angle from an erected state, the rotation side through hole 420 does not match the fixed side through hole 560. The waveguide of an antenna-side and the waveguide in the casing are disconnected.

摘要： PROBLEM TO BE SOLVED: To prevent generation of failure or breaking of wire in the vicinity of connections even in a long time use by fixing a depressing member for depressing a flexible wiring substrate connected with a rotation member on the connections side to the rotation member. SOLUTION: For example, an electronic apparatus as a radar 10 is provided with a depressing member 13 which pushes on a printed wiring substrate 14 where a flexible wiring substrate 15 is fixed on the rotational axis 12b of an antenna 11. The member 13 is desirably made a curve at the tip end 13a and formed with fluoric resin superior in lubrication. With this constitution, if the antenna 11 periodically rotates, the location from the connection part 15a of flexible wiring substrate 15 to the location contacting the member 13 does not deform much and so the concentration of stress to the contact part 15a is avoided. Also as the tip end 13a of the member 13 is curved in the constitution, scratching of the flexible wiring substrate 15 due to the friction with the tip end 13a is prevented.

摘要： PROBLEM TO BE SOLVED: To reduce power loss and to make this device small-sized by removing a T-branch or the like in a radar device or the like. SOLUTION: This device is provided with a cylindrical resonance hollow body 20, resonating with prescribed operating frequencies by using a TE011 which is axially symmetric, and a first waveguide 18 is connected through a connection window 24 with the side face of the resonating hollow body 20. On the other hand, a rotary body 21 is arranged so as to be freely rotatable on the upper edge face of the resonation hollow body 20, and a second waveguide 26 is connected through a conduction window 25 with the rotary body 21. Thus, power losses can be reduced, and when this is integrated into a radar device or the like, it can function as a T-branch. Moreover, spuriousness can be suppressed. Also, the second waveguide may be coaxially arranged, so as to be freely rotatable inside the resonating hollow body.
