IPC: H01Q19/00
Filed: 1983-04-19
Abstract: PURPOSE:To omit a circular/angular converter, to obtain an economical antenna and to reduce the quantity of reflected waves from a glid type circular polarized wave generator to a pyramid horn by constituting a parabolic antenna by a parabola, a pyramid horn by constituting a parabolic antenna by a parabola, a pyramid corn, a down converter, an apex matching plate and the glid type circular polarized wave generator. CONSTITUTION:The circular polarized wave parabolic antenna is constituted by the parabola 1, the pyramid horn 14, the down converter 6, the elliptical cone type apex matching plate, and the glid type circular polarized wave generator 10 The terminal of the converter 6 is formed like a square and directly connected to the pyramid horn 14, so that the circular/angular converter can be omitted. Straightly polarized radio waves are radiated from the pyramid horn 14 and converted into circularly polarized waves by the glid type circular polarized wave generator 10 and the converted circular polarized waves are reflected, irradiated to the parabola 1 and then radiated to the space. The center axis of the pyramid horn 14 is made coincide with that of the apex matching plate 15 and the longitudinal direction of an opening of the pyramid horn 14 is made coincide with the apse line direction of the ellipse of the apex matching plate 15. Thus, the quantity of reflected waves from the circular polarized wave generator 10 to the pyramid horn 14 can be reduced.

Title: Frequency control circuit
Inventor: SATOMI HIDEO
IPC: H04N5/95
Filed: 1989-03-20
Abstract: PURPOSE:To prevent a counter output signal from applying to a VCO at head changeover and to avoid abnormal control by providing an edge detection circuit and resetting an oscillated output signal counter in response to an edge pulse. CONSTITUTION:When a horizontal synchronizing signal is fed from a terminal 8 to a control circuit 7, a switch is closed by a signal S1 and a counter 2 counts a VCO signal for 4H period and pauses for 1H period. A window comparator 4 takes a pause of 1H period, the counter 2 is reset for 1H period and restores to the initial state, and this processing is repeated. When an RF switch pulse is fed from a terminal 10 via an edge detection circuit 9 to the control circuit 7, the control circuit 7 is reset and a signal S3 is generated for an edge detection output period only to control the counter 2. The pulse is counted for H after the reset. Even when the horizontal synchronizing signal is fluctuated by 1H based on the change in the RF switch pulse, since the pulse is not counted for the fluctuation period, the pulse is counted based on the succeeding correct horizontal synchronizing signal to prevent the error control of the VCO.
