Title: Frequency compounding device
Inventor: KURIHARA TAKENORI
IPC: H03B21/00
Filed: 1978-12-26
Abstract: PURPOSE:To obtain the steady output signal featuring the desired frequency through control given to one oscillator along with compensation given to the frequency fluctuation of other oscillators by applying the frequency conversion signal of the group and the output of the reference oscillator or the like to the comparator and then giving the frequency control to the variable frequency oscillator with the output error signal. CONSTITUTION:Mixers M1-M5 mixe up the output of variable frequency oscillator 01 plus fixed frequency oscillators 02 and 03 each and transmit the output signal of the desired frequency after the frequency conversion. Then the output oscillators 01 puls 02 and 03 are mixed in sequence with higher harmonic output of the optional order which is contained in reference oscillator 0r, thus performing the frequency conversion. Here the conversion signal plus the output of oscillator 0r or steady auxiliary reference oscillator 0s is applied to phase or frequency comparator P, and the output error signal is applied to oscillator 01 as the frequency control signal. In such way, one oscillator can be controlled by one set of the phase or frequency control groups to secure the compensation for other oscillators' frequency fluctuation in a simple structure.

Abstract: PURPOSE:To perform packaging of a lead frame with all the external leads connected stably, by adhering a low-melting-point metal film on a part of one face of each of the external leads such that the lead is thicker at that part than the other parts. CONSTITUTION:A lead frame 1a includes external leads 4 each having a low- melting-point metal film 11 adhered on a part of one face thereof so as to be thicker in that part than the other parts.
