Title: Buffer amplifier for oscillator
Inventor: NAGASHIMA TOSHIO
IPC: H03F3/60
Filed: 1986-05-28
Abstract: PURPOSE:To obtain a flat oscillation signal output with an excellent separation characteristic over the variable frequency by using a FET as a buffer amplifier element, connecting a line having a nearly 1/4 wavelength of the oscillation frequency to a gate of the FET and coupling the 1/4 wavelength line and the FET or a bias line of a transistor (TR). CONSTITUTION:A gate input line 19 consists of a microstrip line of a nearly 1/4 wavelength corresponding to 2.5GHz in the oscillation frequency variable range. The gate input line 19 and the emitter bias line 15 are both made up of a line whose characteristic impedance is enarly 80OMEGA and both the lines are coupled in parallel. An oscillation signal fed from the emitter of the oscillation TR 1 is amplified by a common source amplifier of the FET 18 and inputted to the gate of the common source amplifier comprising a FET 26. After the signal is amplified again, the result is outputted to an oscillation signal output terminal 34, and the oscillation signal is fed to a frequency mixing circuit 50. A broad hand and flat coupling characteristic is ensured for the oscillation signal by the parallel coupling circuit comprising the bias line of 1/4 wavelength corresponding nearly to the center frequency of the oscillation frequency variable range.

Title: Automatic preservation of input program text
Inventor: NISHIKAWA MASAZUMI
IPC: G06F9/06
Filed: 1983-07-06
Abstract: PURPOSE:To decrease the frequencies for reinput of program texts as well as input of commands by using one-line input detecting means and a preservation period deciding means in order to preserve a program text supplied automatically to a secondary memory. CONSTITUTION:When a program text is fed by an amount equivalent to one line, one-line input detecting means 31 detects this input and gives an output 31A to a preservation period deciding means 32. Then a deciding means 34 reads out the present time point from a timepiece module 11 and the time point which is automatically preserved in the preceding time from a register 33 and produces a difference between both time points. Then the means 34 decides whether said difference exceeds 10min or not. If this difference exceeds 10min, it is transferred and preserved in an area A or B of a secondary memory 8 via a write control means 35, etc. Thus a program which is automatically fed is transferred and preserved to a secondary memory from a primary memory by using the means 31, etc. This can decrease the frequencies for reinput of program texts and input of commands for preservation owing to a service interruption, etc.
