Title: Current mirror circuit
Inventor: HIRAOKA YUKIO
IPC: H03F3/343
Filed: 1988-12-15
Abstract: PURPOSE:To reduce the effect of the dispersion in the mirror ratio due to the dispersion early voltages by connecting a resistor in series between a collector of an output transistor(TR) and an output terminal so as to improve the deviation of the ratio (mirror ratio) of an input current to an output current. CONSTITUTION:One terminal of a resistor 10 is connected to a collector of the output TR 7 and the other terminal of the resistor 10 is connected to an output terminal 9. When a current source is connected to an input terminal 8, the current is supplied to a TR 6 and also fed to the TR 7. In this case, the resistance 10 is selected so that the collector-emitter voltage of the TRs 6, 7 is made coincident. Suppose that the current amplification factor of the TRs 6, 7 is sufficiently large and the VBE is identical, the input current flowing to the TR 6 and the output current flowing to the TR 7 are very close to each other. Thus, the deviation in the mirror ratio due to the Early effect is improved and the effect of the dispersion in the mirror ratio due to the dispersion in Early voltages is reduced.

Filed: 1989-12-06
Abstract: PURPOSE:To secure privacy by convering a voice signal between end-end users and sending a data with no meaning at all to a transmission line so as to allow only talkers to understand the data. CONSTITUTION:Plural code conversion tables are prepared to a terminal equipment, one conversion table 10 is selected according to a decoding key and a true voice code is not transmitted to me transmission line but a code not understandable to a 3rd party is sent.

Title: Multi-output power supply switching regulator
Inventor: TANUMA JIRO
IPC: H02M3/28
Filed: 1989-12-07
Abstract: PURPOSE:To suppress uncontrolled voltage by varying the gap in the core of a high frequency transformer upon variation of the uncontrolled output thereby varying the magnetic resistance accurately. CONSTITUTION:When a light load is connected between the output terminals 34c, 34d, energy can not be consumed and uncontrolled output V2 increases. When the uncontrolled output V2 exceeds a voltage level set through a Zener diode in a detecting means 31, a driving means 32 functions to vary the gap. Consequently, magnetic resistance of a transformer 25 varies. Since no dummy load resistor is required, circuit forming area is reduced and temperature rise is suppressed. Furthermore, load variation range can be enlarged while suppressing uncontrolled output V2.
