摘要： A time constant circuit capable of switching the characteristic, which is realized by a combination of an equivalent resistor made up of a switched capacitor and an ordinary capacitor, comprises a capacitor (20, 26, 27) of the switched capacitor or the time constant circuit connected in parallel to a series circuit including a switching device (29, 51, 69) and an additional capacitor (28, 47, 52, 56, 58). The characteristic is switched by turning on and off the additional capacitor by the switching device. The direct connection of a plurality of equivalent resistors with a plurality of switched capacitors and ordinary capacitors makes up an equalizer. The capacitor making up a switched capacitor is connected with a switching device and an additional capacitor so that the frequency characteristic of the equalizer is switchable by turning on and off the switching device. Each of the capacitors making up the switched capacitors, the capacitors making up the time constant circuits and the additional capacitors has an end thereof grounded without fail. All the elements are thus capable of being formed in the same integrated circuits.

摘要： A motor control apparatus for driving and controlling a motor, in which a signal frequency proportional to a rotation number of the motor is converted into a d.c. voltage by a frequency/voltage converter so as to drive and control the motor by the d.c. voltage. The apparatus comprises a first, a second, and a third pulse generator (12, 13, 14) for successively producing a first, a second, and a third repetitive pulse, respectively, in response to a signal period proportional to the rotation number of the motor; a constant current source (36, 48, 56); a first reset circuit (17) driven by the third pulse to reset an output current of the constant current source; a first capacitor (20) connected to the first reset circuit in parallel with the first reset circuit and charged by the output current of the constant current source; a sampling circuit (18) driven by the second pulse to derive a saw tooth wave signal appearing across the first capacitor; a second reset circuit (19) driven by the first pulse; a second capacitor (21) connected to the second reset circuit in parallel therewith for charging the saw tooth wave signal through the sampling circuit; and a circuit (49, 57) for changing a pulse width of at least one of the first, second and third pulses substantially in proportion to the output current of the constant current source.

摘要： Disclosed is a speed and phase control system for a moving apparatus driven by an electric motor, or the like, and provided with a speed control system (22, 23) for controlling the moving apparatus to an initially set speed, a phase control system (25) for synchronizing the phase of the moving apparatus with a reference signal (29), and an error correction device (24) storing therein a target value of and for comparing an actual speed or a phase of the moving apparatus with the target value to detect an error therebetween to thereby correct the initially set value in accordance with the error, whereby control is made such that the moving apparatus is operated at the target value of speed and phase thereof. Further, the error correction device is cut off from the speed control system when the speed reaches a value near the target value and at the same time the operation of the phase control system is started.

摘要： In a helical scan-type video tape recorder, a tach signal is generated as a reference signal when the rotating heads (2, 3) trace the vertical blanking period recorded portion of the tracks on a magnetic tape (1) moving at the standard speed, and this reference signal and a signal indicative of the level-reduced portion (N) of the reproduced video signal (V) from the rotating heads are compared in phase with each other to produce a phase difference signal (T), by which the transportation of the magnetic tape is controlled so that the level-reduced portion coincides with the vertical blanking period of the reproduced video signal.

摘要： A method and apparatus for reproducing a still picture without a noise bar from a magnetic tape in a video tape recoder. The magnetic tape is stopped in a moment at a leading edge of a rotating phase detecting signal of rotating heads or a reproduced control signal generated after a still reproduction command signal, and it is detected whether the nose bar exists within a vertical blanking period or not in a still reproduction state. If the noise bar exists within the vertical blanking period, the still reproduction state is continued. In the case that the noise bar does not exist within the vertical blanking period, the magnetic tape is run at a slow speed, and when the noise bar gets into the vertical blanking period, the feeding of the magnetic tape is stopped.

摘要： A transistor circuit is used as a signal amplifier which has almost no possibility of oscillation in an IC. The transistor circuit includes a cascade connection of differential amplifiers. Each of the amplifiers comprises a differential pair of bipolar transistors and an enhancement-type MOSFET as a constant current source. The MOSFET of each amplifier is connected in the common source mode, and the drain is connected to the emitters of the differential pair of bipolar transistors. The sources of all the MOSFETS are connected to a common ground-line.
