摘要： A toner supply container has a container body and a conveyance member rotatably arranged inside the container body and which conveys toner toward a discharge opening of the container body when driven to rotate by external force. The conveyance member includes a cylindrical rotary body and a screw blade member wound around the cylindrical rotary body so that the screw blade member stands on an outer circumferential surface of the cylindrical rotary body. The inner surface of a bottom wall of the container body includes a cylindrically curved surface identical to a part of a circumferential surface of an imaginary cylinder whose axis is substantially the same as a rotation axis of the conveyance member. A curvature radius of the cylindrically curved surface is set so the conveyance member rotates in a state where an outer circumferential edge of the screw blade member substantially slides on the cylindrically curved surface.

摘要： A metal mold is disposed adjacent to the outer circumference of a base ring, and has a molding face in the inner circumference and a plurality of grooves for forming beads on the molding face along the circumferential direction. A coil for electromagnetic forming is disposed adjacent to the inner circumference of the base ring. When a momentary large current is applied to the coil in this arrangement, the diameter of the base ring is expanded by pressing the base ring toward the molding face of the metal mold such that the base ring is molded into a shape corresponding to the molding face by electromagnetic forming. Improvements such as a metal mold capable of degassing, a separable metal mold, roll-correcting after electromagnetic forming, application of momentary large current over several times, a metal mold with a cutting blade, use of a base ring with a large number of holes, and a metal mold with positioning means are then added. With these improvements, a highly accurate cylindrical ring with beads can be produced at low cost and with high productivity.

摘要： A frequency converter includes a multiplying circuit, a load circuit, and an output buffer circuit. The multiplying circuit is arranged to multiply an RF signal and an LO signal and output a difference frequency signal with a frequency, which is the difference between the frequencies of the two signals, from its output terminal. The load circuit is arranged to connect the output terminal of the multiplying circuit to a power supply. The output buffer circuit is arranged to have an input terminal connected to the output terminal of the multiplying circuit, and an output terminal for outputting a signal to the next stage. A notch circuit for removing an undesired signal frequency component is combined in the load circuit. The notch circuit has an impedance characteristic in which the impedance is abruptly reduced to provide a valley point at the undesired signal frequency.

摘要： A local signal of a predetermined frequency is supplied to an input terminal of a local signal input section. The local signal is applied to a control input terminal of a variable current supply and, in accordance with the local signal, a current is output from a variable current supply and sent to a phase-shifting section. The phase-shifting section includes two resonance circuits each comprised of a capacitor and inductor. The two resonance circuits are connected in parallel with a linear element constituting the local signal input section to output first and second output signals of the same frequency as that of the local signal and whose phases are shifted by a predetermined amount. The respective output signals of the phase-shifting section are output to a next stage through a signal output section comprised of two sets each of a current supply and transistor.

摘要： An integration circuit includes a differential amplifier constituted by at least two bipolar transistors serving as amplifying elements, a capacitor connected, as a load, across the collection electrodes of the differential amplifier, and a field-effect transistor having source and drain electrodes connected between the emitter electrodes of the two bipolar transistors. A control voltage is applied to the gate electrode of the field-effect transistor. By changing the resistance value between the source and drain electrodes of the field-effect transistor using a gate voltage, the transconductance of the differential amplifier is changed over a wide range. As a result, the time constant of the integration circuit is changed, such that if the integration circuit is used for an active filter, for example, the cut-off frequency can be changed by changing the time constant of the integration circuit.

摘要： A differential amplifier with improved linearity. The amplifier includes a circuit comprised of two emitter-coupled pairs, each pair being formed by two transistors, with connections between corresponding collectors, and constant voltage sources for producing offsets between corresponding bases of the emitter-coupled pairs. The improved linearity is achieved by obtaining outputs as sums of collector currents with offsets. The emitter areas of the transistors can be of the minimum size available. This feature, when combined with the use of emitter-followers as the constant voltage sources, enable the differential amplifier to achieve a high S/N ratio, a good high-frequency characteristic, a high direct current gain, and a high-speed operation capability along with the improved linearity. In addition, the linearity is further improved by using additional diodes connected to the transistors.
