Title: Multiplying circuit
Inventor: NAKAMURA TAEKO
IPC: H03B19/14
Filed: 1986-09-19
Abstract: PURPOSE:To miniaturize and lighten a circuit and to improve an output power by constituting a band-pass filter of a ring resonator. CONSTITUTION:Since an open stub 11 of the 1/4 wavelength of a double wave to occur at a FET 7 is added to microstrip/slot line converters 9 and 10, an impedance in microstrip/slot line converters 9 and 10 comes to be short by the double wave and converted to a ring resonator 12 composed of a slot line. At this time, since the whole circumferential length of the ring resonator 12 is designed to the length of one wavelength of the double wave, resonance is generated to the double wave by the ring resonator 12 and the double wave is guided to an output terminal 2. Consequently, the ring resonator 12 is operated as the band-pass filter having a band-pass characteristic in the resonance frequency. Namely, since a band-pass filter 13a is constituted of the ring resonator, the circuit can be miniaturized and lightened and the output power can be improved.

Abstract: PURPOSE:To prevent the underdrive or overdrive of a switching transistor by the ripples of load by providing it with first auxiliary winding, which drives the transistor whose emitter is connected to the base of a switching transistor, and connecting a diode to the winding end of the first auxiliary winding, whose winding direction is opposite to that of the main winding, and connecting on end of a capacitor to the winding start. CONSTITUTION:When load becomes large, a feedback circuit 12 feeds back the information of voltage drop to the primary side, and the oscillation frequency of a switching transistor (STr) 2 becomes slow. Thereupon, the output voltage of the winding 9 of a transformer 3 rises to the specified value. With the increase, the output voltage of the winding 4 becomes larger by cross regulation. When the transistor 6 is turned on, the output voltage of the winding 4 adds to the base of the STr 2, and it supplies the STr 2 with a large quantity of base current. When the load becomes small, the information of the voltage rise is fed back to the primary side, and the oscillating frequency of the STr 2 increases, and it supplies a small quantity of base current.

Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To urge the user to conduct proper countermeasures by informing the user effectively of occurrence of a communication error based on subscription/non-subscription to a number display service due to a fault of a network or a terminal. SOLUTION: The terminal discriminates subscription/non-subscription to a number display contract at the arrival of an incoming call, and when the terminal detects a call signal before transmission of a primary reply signal regardless of the subscription having been contracted, the terminal displays and outputs information denoting it. Concretely, the terminal devotes itself to the reception of the V.23 for a prescribed time after the primary reply, and it transits a transmission sequence of a reception end signal when the terminal can receive the V.23 and it conducts display and output for an inquiry of a manufacture. When the terminal cannot receive the V.23, the terminal transits to transmission of an initial identification signal, and if it detects a facsimile protocol signal from an opposite machine, it conducts display and output for inquiry of a network provider.
