摘要： A phase signal is modulated in quadrature modulation by a quadrature modulator, and the frequency of this modulated phase signal is converted into carrier frequency by a frequency converter. An amplitude signal extracted from the modulating signal is delayed by a delay circuit, and an output gain signal designating the output average power gain is supplied to the output signal of the delay circuit. Synchronization of this frequency modulated phase signal and the amplitude signal delayed and added to the output gain signal allows to obtain an RF signal with little out of band undesired component even if the modulating signal contains amplitude variation. Therefore, the RF signal with little out of band undesired component is output even if the modulating signal contains amplitude variation.

摘要翻译： 相位信号由正交调制器在正交调制中调制，并且该调制相位信号的频率由变频器转换成载波频率。 从调制信号提取的振幅信号被延迟电路延迟，并且将指定输出平均功率增益的输出增益信号提供给延迟电路的输出信号。 该频率调制相位信号与被延迟并相加到输出增益信号的振幅信号的同步允许获得具有极小带外不需要分量的RF信号，即使调制信号包含振幅变化。 因此，即使调制信号包含幅度变化，也输出具有极小带外不需要分量的RF信号。

摘要： A vehicle is installed with an integral transaxle apparatus constructed so that a single housing contains left and right axles, a driving hydrostatic transmission (HST) having a variable displacement first hydraulic pump and a first hydraulic motor fluidly connected with each other, a steering HST having a variable displacement second hydraulic pump and a variable displacement second hydraulic motor fluidly connected with each other, and a differential unit differentially connecting the axles with each other so as to be driven regularly or reversely by the output of the driving HST and to differentially drive the axles while receiving the output of the steering HST, wherein the first hydraulic pump receives power of a prime mover and has a first movable swash plate, and the second hydraulic pump receives power of the prime mover independently of the first hydraulic pump and has a second movable swash plate. The vehicle is also provided with driving operating means for slanting operation of the first movable swash plate for switching the travelling direction between forward and backward and for changing the travelling speed, and steering operating means for slanting operation of the second movable swash plate so as to determine the leftward and rightward cornering angle. The second hydraulic motor has a third movable swash plate interlocking with the driving operating means so that the slanting direction of the third movable swash plate is changed oppositely with respect to its neutral position according to the travelling direction switching operation of the driving operating means, whereby the vehicle turns laterally in the same direction of leftward and rightward steering operation of the steering operating means whether the vehicle travels forward or backward.

摘要： An axle driving apparatus in which a hydraulic pump and a hydraulic motor which constitute a hydrostatic transmission are disposed on a center section. In a horizontal portion of the center section are provided a pair of linear oil passages in parallel to each other. A pair of arcuate ports are provided on a pump mounting surface formed on the horizontal portion of the center section. The pair of arcuate ports are substantially perpendicular with respect to the direction in which the oil passages extend. The axis of slanting movement of a movable swash plate of the hydraulic pump extends laterally of the vehicle body on which the axle driving apparatus is provided. The rotating direction of an arm provided on a control shaft for slantingly operating the movable swash plate is coincident with the operating direction of a control rod connected with a speed changing member. Thus, the link mechanism for connecting the speed changing member and the control arm for the movable swash plate is simplified.

摘要： A hydrostatic transmission is provided comprising a hydraulic pump and a hydraulic motor fluidly connected with each other through a closed fluid circuit. Pistons press against a control arm connected with a movable swash plate of the hydraulic pump and generate a friction force when the movable swash plate, which has been rotated slantwise, automatically returns toward the neutral position by a neutral return spring. The movable swash plate gradually returns to the neutral position by pressure of the piston. A discharging oil hole is open at the utmost end of each of the pistons for draining a portion of operating oil which operates the piston in the closed fluid circuit to the interior of a housing. Grooves are formed along a surface of the control arm abutting against the pistons. When the movable swash plate is rotated between the neutral position and a predetermined position, the discharging oil holes are connected to the interior of the housing through the grooves so as to release the oil pressure out of the closed fluid circuit. Thus, braking shock can be moderated and the neutral position can be expanded.

摘要： An electric shaver includes: a main body; an outer blade provided to an end of the main body and having a blade hole defined by a bar; and an inner blade provided inward of the outer blade and configured to reciprocate in a longitudinal direction of the outer blade to cut hair in the blade hole with the outer blade. The bar has a hair raising portion coming in contact with hair upon movement of the outer blade on a skin surface to raise hair up from the skin surface. A contact pressure on the skin surface to be exerted by the outer blade in a first portion of the outer blade is greater than that in a second portion of the outer blade. Hair raising performance in raising hair up from the skin surface in the first portion is smaller than hair raising performance in the second portion.
