Filed: 1981-08-26
Abstract: PURPOSE:To narrow down the dynamic range of a detector and to eliminate the need for a divider, by exercising AGC over an amplifier for a received signal while using the detection output voltage of a carrier as a control signal. CONSTITUTION:A received burst signal is passed through an AGC amplifier 11 and divided into two; and a band-pass filter 3 extracts only a carrier from the burst signal, and a band-stopping filter 4 removes only the carrier from the burst signal. Outputs of the filters 3 and 4 are detected by detectors 5 and 6 and inputted to sample holding circuits 7 and 8, where they are sampled and held according to a nonmodulation forecasting signal. The output of the sample holding circuit is applied as an AGC control voltage to an AGC amplifier 11. Consequently, a carrier detection voltage has no relation with the input level of the received burst signal and a noise detection voltage substitutes for a scale of C/N ratios directly to be displayed on a display 10.

Abstract: PURPOSE:To realize rigid and stabilized mounting of components by conducting a rust-proof treatment immediately after desmear treatment before a flux treatment is conducted thereby bringing the solder into direct tight contact with copper paste exposed at a through hole part. CONSTITUTION:A through hole 3 in a printed board 1 is filled, by screen printing, with a copper paste 4 which is then thermally hardened in a hot air dryer. A hardened copper paste 5 protruding from a copper foil 2 at a land part is then flattened 6 by buffing until it becomes flush with the copper foil 2 before desmear treatment is conducted. The desmear treatment dissolves and removes resin from the surface of the copper foil 4 thus exposing the copper which is immediately subjected to rust-proofing without drying. In other words, the surface of copper is coated with a chelate compound in order to protect the copper temporarily against oxidation before the flux treatment is conducted. Upon finish of flux treatment, soldering is conducted thus obtaining a printed circuit board provided with a solder 7.
