    摘要: 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.

    摘要: A relief pressure controlling device comprises a driving side relief pressure controlling valve, a capacity detector which detects the capacity of a hydraulic pump, and an engine throttle opening detector. When the hydraulic pump and the hydraulic motor which are connected by a first oil passage and a second oil passage constituting a hydraulic closed circuit are driven by an engine, the relief pressure controlling valve controls the relief pressure of the oil passage on the driving side that is either the first oil passage or the second oil passage whose pressure becomes higher than the other, to a target relief pressure. The target relief pressure is determined in correspondence with the engine output and corrected on the basis of the pump efficiency which is predetermined in relation to the capacity of the hydraulic pump and to the throttle opening, and this corrected target relief pressure is set as a driving side target relief pressure. The driving side relief pressure controlling valve performs a relief pressure control so that the relief pressure of the driving side oil passage will become the driving side target relief pressure, which is set in correspondence with the capacity of the hydraulic pump and the engine throttle opening.

    摘要: A hydraulic continuously variable transmission for use on a vehicle comprises a hydraulic variable pump, which is driven by an engine, and a hydraulic variable motor, which is driven by oil discharged from the hydraulic variable pump to drive wheels. In addition, this transmission includes shift position detecting means, which detects a shift position, and vehicle stop detecting means, which detects whether the vehicle is in halt. In this transmission, when the vehicle stop detecting means detects that the vehicle is in halt and the shift position detecting means detects that the shift position is in a forward or rearward drive position, the discharge capacity of the hydraulic variable motor is set to a maximum, and the discharge capacity of the hydraulic variable pump is controlled to a predetermined capacity (first predetermined capacity) in correspondence with the shift position. Thereby, the vehicle is prevented from relapse phenomenon, i.e., being dragged in the direction opposite to the direction set with the shift lever when the vehicle is stopped on a slope.

    摘要: A signal generating section 10 outputs an amplitude signal and a frequency signal by conducting a signal processing on inputted data. A regulator 31 outputs a signal that is proportional to a magnitude of the amplitude signal. The signal outputted from the regulator 31 passes through a low pass filter 41, and is inputted into a power amplifier 51. The power amplifier 51 conducts an amplitude modulation on a frequency signal on which an angle modulation is conducted by an angle modulation section 20, using a signal outputted from the low pass filter 41. A controlling section 60 controls an amount of attenuation of a radio frequency component at the low pass filter 41 based on information such as: a modulation method of the inputted data; a modulation condition of the inputted data; a reception band; an output power of a modulation signal; and a frequency of the modulation signal.

    摘要: 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. The feedback signal generation section 16 is attained by a power amplifier having the same configuration as the amplitude modulation section 15 and a smaller circuit scale.

    摘要: 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. Based on a predetermined characteristic, a compensating filter (12) wave-shaping-processes the amplitude signal. A regulator (14) outputs a signal in accordance with a magnitude of the signal which has been wave-shaping-processed by the compensating filter (12). An amplitude modulator section (15) amplitude-modulates the angle-modulated signal by using the signal outputted from the regulator (14). A characteristic of the compensating filter (12) is an inverse of a transfer characteristic between an input at the regulator (14) and an output at the amplitude modulator section (15).

    摘要: A channel layer made of n-type GaAs doped with Si, a hole absorption layer made of InGaAs having a valance band higher in energy level than that of GaAs, and an undoped layer made of GaAs are formed sequentially on a semi-insulating substrate made of GaAs. A gate recess region having a pair of sidewall portions each consisting of an upper sidewall composed of the undoped layer and a lower sidewall composed of the hole absorption layer is formed on the channel region. The channel region is exposed in the gate recess region. An indent having an undercut configuration is formed in the lower sidewall of the gate recess region. A gate electrode is formed to extend over a stepped portion composed of the sidewall portion of the gate recess region closer to a drain electrode.
