Abstract: PURPOSE:To stabilize a local oscillation signal and to prevent beat disturbance by selecting either the oscillation output of a crystal oscillator, a crystal oscillation frequency, and a second tuning voltage having a prescribed frequency gap, or the oscillation output equivalent to the crystal oscillation frequency and a first tuning voltage, and supplying them to a tuner mixing part and a high frequency amplifier part. CONSTITUTION:A local oscillation frequency signal corresponding to a channel-selection frequency is outputted from the crystal oscillator 42, and an oscillation operation is performed with the same frequency as that of the signal at a frequency to voltage conversion means and a first PLL 101, then, the first tuning voltage is outputted. And the second tuning voltage is outputted from a tuning voltage output means and a second PLL 102, and a developmental frequency component is provided with the crystal oscillation frequency and the prescribed frequency gap. Next, either the pair of the oscillation output of the crystal oscillator 42 and the second tuning voltage, or that of the oscillation output of the first PLL 101 and the first tuning voltage is selected as the local oscillation signal to the tuner mixing part 27 and the tuning voltage to the high frequency amplifier part.

IPC: H01B17/46
Filed: 1986-08-12
Abstract: PURPOSE:To enable a worker to easily find a lightning protection insulator in a deterioration state on the ground or in the sky by providing the lightning protection insulator with a leak current detection sensor and emitting light or generating a sound when the current exceeds a prescribed value. CONSTITUTION:The lightning insulator 3 normally has its lightning protection element held high in resistance and is prevented from having a ground fault, but when an overvoltage due to a lightning surge or opening/closing surface is applied to the lightning protection insulator 3, a current flows from an iron tower 1 to the ground through the lightning protection element. When the case like this takes place frequently or when water enters the insulator 3, this lightning protection element deteriorates gradually and a fine leak current begins to flow through the lightning protection element gradually. This leak current is detected by a leak current detection sensor 4 and when its current values exceeds, for example, 30mA, a signal is generated and sent to a control part 8 through a lead line 5 to operate the turning-on circuit for a lamp 6, which is powered on by a storage battery to light or blink.
