    • Provided is a transmission circuit which can adjust a difference between signal delay amounts in the amplitude path and the phase path with a low power consumption. An amplitude modulation section 15 amplitude-modulates a phase modulation signal outputted from a phase modulation section 14 with a voltage control signal provided by a regulator 13 to generate a transmission signal for an output of an antenna. Similarly, a feedback signal generation section 16 amplitude-modulates the phase modulation signal with the voltage control signal to generate a feedback signal FB. The signal FB is fed back to a delay adjustment section 12 and used for calculating and adjusting the difference between the signal delay amounts in the amplitude path and the phase path.

    • Provided is a transmitter circuit capable of operating with low distortion and high efficiency even in a modulation method using wide modulation bandwidth. In the transmitter circuit, a signal generation section (11) generates an amplitude signal and an angle-modulated signal.

    • A hydraulic continuously variable transmission for use on a vehicle comprises a hydraulic closed circuit, first and second pressure controlling means, brake operation detecting means and deceleration detecting means. The hydraulic closed circuit includes a hydraulic pump, a hydraulic motor, a first oil passage connecting a port of the hydraulic pump with a port of the hydraulic motor and a second oil passage connecting another port of the hydraulic pump with another port of the hydraulic motor, and first and second pressure controlling means control the pressures of the first and second oil passages, respectively. If the deceleration of the vehicle is greater than a standard deceleration when the operation of the brake is detected, then the pressure of the first or second oil passage whose pressure is higher than that of the other is lowered to a predetermined low pressure that is higher than the pressure of either oil passage which is lower by either the first or second pressure controlling means. This predetermined low pressure is determined in reverse proportion to the engine rotational speed, thus preventing the engine from stalling when the wheels are locked up in an abrupt braking operation.
