摘要： An electronic tuning circuit for AM receiver is disclosed which is so designed that tracking errors are minimized by increasing the accuracy of constants for tuning coils, oscillation coils and capacitance elements incorporated in an antenna tuning circuit, a high-frequency amplifier circuit and a local oscillator circuit which constitute the electronic tuning circuit. After the electronic tuning circuit has been mounted in place, tracking adjustment is effected at one point of the receiving frequency band, or alternatively no such adjustment is required.

摘要： A lockup control system for an automatic transmission is provided with an electromagnetic valve 11 and a spool valve 13. When the electromagnetic valve 11 is inactive, the spool valve 13 is set so that a pressure at an OFF port 171 of a torque converter 12 is higher than that of an ON port 172, thereby opening a lockup clutch mechanism 19. When the electromagnetic valve 11 is activated, its control pressure Pc becomes lower than a secondary pressure PL2and the spool valve 13 is actuated so that the control pressure Pc is supplied to a clutch control chamber 18. As a result, the lockup clutch mechanism 19 is closed, thereby setting the lockup state. At this time, the control pressure Pc acts directly on the clutch control oil chamber 18, so that the lockup clutch mechanism 19 is controlled with high precision.

摘要： A receiver equipped with an electronic tuning circuit which uses voltage-variable reactance elements such as variable-capacitance diodes or the like in the radio-frequency tuning circuit and oscillation tuning circuit thereof. The oscillation tuning circuit includes a novel padding capacitor constituted by a composite circuit of a variable-capacitance diode and fixed capacitors connected at the position where a conventional padding capacitor is connected. With such an arrangement, it is possible to make tracking error negligibly small over a frequency band ranging from a low receiving frequency to a high receiving frequency, by applying a tuning voltage to the composite padding capacitor.

The second fixed capacitor has its other end connected to a connection point between the padding capacitor and the first variable capacitance diode.
