Title: Capacitance changeover device for capacitor
Inventor: TAKAZAWA ATSUYUKI
IPC: H03H11/12
Filed: 1989-11-14
Abstract: PURPOSE:To reduce a leakage current and an on-resistance by connecting an operational amplifier to the output and providing the operational amplifier between a capacitor and a semiconductor switch. CONSTITUTION:For example, when a semiconductor switch 1 is connected to the output of an operational amplifier 3 and a semiconductor switch 2 is grounded, a voltage at both electrodes of a capacitor C3 is kept the same which is equivalent to the circuit without the capacitor C3. Then the equivalent circuit is a time constant circuit comprising a resistor R1 and a capacitor C4. In such a case, each switch contact part of the semiconductor switches, 1, 2 is driven with a low impedance, then the leakage current of the semiconductor switch 1 is all absorbed by the operational amplifier 3 and the leakage current of the semiconductor switch 2 flows to ground.

Title: Hilbert transformation device
Inventor: ONISHI MAKOTO
IPC: H03H17/02
Filed: 1987-11-24
Abstract: PURPOSE:To obtain a Hilbert transformation device with high accuracy in both the amplitude characteristic and the phase characteristic with less hardware by combining the method by a noncyclic filter and the method forming a 90 deg. phase shifter by a full band filter so as to compensate complementary features of the both. CONSTITUTION:An input signal is given to a Hilbert transformation device comprising a noncyclic filter(FIR) 1 and a Hilbert transformation device comprising full band pass filters APFs 2, 3. The phase characteristic of the output of the FIR is accurate and the amplitude characteristic of the output of the APF is accurate. Thus, the result of root of the sum of the squared in-phase output of the APF and squared orthogonal output is calculated. Similarly, the amplitude of the FIR output is calculated to obtain the amplitude ratio of the both and it is multiplied with the in-phase and orthogonal output of the FIR outputs as the output. That is, the output amplitude of the FIR is corrected by the APF output to obtain a correct Hilbert transformation output. In order to match the output point of times of the FIR and APF, the input signal to the APF is extracted from the midpoint of the delay element array of the FIR from the output if delay elements going backward toward the input side by the delay time of the APF.

Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To improve the waterproofing property of a bobbin by providing notches at the spots of a connecting plate section corresponding to pipe sections and, at the same time, by reducing the thickness of each flange section by inclining the rear surface of the flange section not wound with any exciter coil toward its periphery. SOLUTION: Exciter coils are respectively wound around pipe sections 8 between the connecting plate section 7 and flange sections 9 of a bobbin 4. At the spots of the plate section 7 corresponding to the pipe sections 8, notches 10 are respectively provided. The rear surface 9b of each flange section 9 not wound with any exciter coil is inclined toward it periphery so that the thickness of the section 9 may be reduced toward the periphery. When the exciter coils are wound, therefore, the pressing forces applied to the flanges 9 are relieved, out of the exciter core 1, because the forces are released through the notches 10.  In addition, a molten resin is surely filled into the exciter coils and the whole surfaces of the flanges 9b can be coated surely with the resin even when the flanges 9 are deformed inward, because the inclined rear surfaces 9b of the flanges 9 prevent the flanges 9 from warping beyond the positions of the their base parts.

Abstract: PURPOSE:To obtain a sharp picture without color misalignment in a picture to be displayed even when contrast is being emphasized by adopting the circuit such that the amplification factor amplified by a transistor(TR) is lowered at a peak of a video signal. CONSTITUTION:With a video signal given to a signal input terminal T1, the signal is amplified by the amplification factor depending on TRs 1, 2 and resistors 3, 4 and the amplified video signal is outputted from a signal output terminal T2. The base and emitter current of the TR 1 are increased remarkably at a peak of the video signal, a voltage across a resistor 11, that is, the voltage drop is increased and the collector voltage of the TR 2 is reduced. When the cathode voltage of a silicon diode 10 is below a reference voltage caused at the connection intermediate point of resistors 8, 9, part of the base current flowing through the base of the TR 1 flows through a resistor 8, the silicon diode 10, the TR 2 and the resistor 4. Thus, the base current of the TR 1 is reduced and the amplification factor by the TR 1 is reduced.

Title: Voltage current converter
Inventor: KAWABATA HIDEO
IPC: H03F3/34
Filed: 1985-12-27
Abstract: PURPOSE:To vary accurately a voltage current conversion gain by providing a differential amplifier and a current repeater and making the current flowing to a collector of the 1st transistor (TR) from the current repeater inverse to the current flowing from the collector to the 1st TR to the current repeater. CONSTITUTION:Resistors 18, 21 being emitter loads of TRs 11, 13 are selected so that the same current as the current component flowing to the TR 13 flows to them. Further, the output current from the current repeater 15 is made inverse and of the same level as the output current from the collector of the TR 11. Thus, the initial current by a reference voltage source 3 is cancelled and no current is outputted at an output terminal 16. Only the difference of the signal levels is amplified by a differential amplifier and its output appears at the collector of the TR 11. The output current I is only the current change due to the input voltage and no initial current component by the reference voltage source 3 appears. Thus, the voltage current conversion gain is varied accurately in a desired rate.

Abstract: PURPOSE: To permit a following copying processing instruction in accordance with the size of a copying paper and to perform an effective image forming processing even in the case where the dispersion in temperature distribution occurs on a heat roller because papers continuously pass through. CONSTITUTION: Even in the case where the dispersion in the temperature distribution occurs on the surface of the heat roller 2 because copying papers of a prescribed size continuously pass through, the copying processing concerned is permitted in the case where the size of the copying paper related with the following copying processing instruction is equal to or below the prescribed size, or equal to or below the prescribed size of a copying paper corresponding to the position where the temperature difference occurs on the heat roller 2, and the copying processing is delayed until the dispersion in the temperature distribution on the heat roller 2 is eliminated in the case where the size of the copying paper is above the aforesaid size.  This is because the dispersion in the temperature distribution does not occur in a corresponding area on the circumferencial surface of the heat roller 2 in the case where the size of the copying paper related with the following copying processing command is equal to or below the prescribed size. Thus, a copying processing for the copying paper whose size is exceeding the prescribed size is delayed, then, the surface temperature of the heat roller 2 is made uniform.

Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a metal gasket wherein a stopping function is restrained and the number of part items are reduced by forming the stopper section of a stopper plates to be laminated on a bead base by folding a part whose thickness is reduced more than the plate thickness of the body sections of the stopper plates. SOLUTION: A stopper plate 4 is held between a pair of elastic metal plates 2 and 3 for sealing around the bore holes 5A and 5B of a metal gasket. Folded and overlapped sections 11A and 11B whose total thickness is larger than that of a stopper plate body 10 are arranged around the bore hole of the stopper plate 4 to restrain the deformation quantity of beads. Since the folded sections 11A and 11B are formed with a base part that is thinner than the stopper body 10 and a folded section in an overlapped state, the difference in level (stopping quantity) can be restrained without using other parts such as metal plates and stopper pieces.
