    摘要： A communication apparatus includes a first antenna device connected to a first communication circuit and a first antenna ground, and a second antenna device connected to a second communication circuit and a second antenna ground. The direction in which the first antenna device resonates is away from the direction in which the second antenna device resonates. The first antenna device is provided with a first waveguide passive element which is radiation-coupled with the first antenna device. The second antenna device is provided with a second waveguide passive element which is radiation-coupled with the second antenna device. Because of the function of the first and second passive elements, radio interference between the first antenna device and the second antenna device installed in the communication apparatus can be reduced.

    摘要： An ejector can obtain a sufficiently large suction air quantity without reducing the ultimate vacuum. A diffuser is disposed downstream of a nozzle to form a single Laval nozzle. A suction port is provided between the nozzle and the diffuser. The inlet of the diffuser is enlarged in width so that the side walls thereof extend approximately parallel to each other along the axis of the diffuser over a predetermined length. When air is caused to flow from an inlet closer to the nozzle toward an outlet by the engine intake negative pressure, the flow velocity at a throat portion reaches the sound velocity owing to the effect of the Laval nozzle. Consequently, a high negative pressure is generated at the suction port. The parallel portion formed by enlarging the inlet of the diffuser allows the suction air quantity to be increased without reducing the effect of the Laval nozzle.

    摘要翻译： 喷射器可以获得足够大的吸入空气量而不降低极限真空度。 扩散器设置在喷嘴的下游以形成单个拉瓦尔喷嘴。 在喷嘴和扩散器之间设有吸入口。 扩散器的入口的宽度被扩大，使得其侧壁沿着扩散器的轴线在预定长度上彼此大致平行地延伸。 当通过发动机进气负压使空气从更靠近喷嘴的入口流向出口时，由于拉瓦尔喷嘴的作用，喉部处的流速达到声速。 因此，在吸入口处产生高的负压。 通过扩大扩散器的入口而形成的平行部分允许增加吸入空气量而不降低拉伐尔喷嘴的效果。

    摘要： Even when a rigidity table stored in a RAM at the time of a start of a brake operation does not coincide with an actual rigidity characteristic of an electric caliper which changes according to brake conditions including how often and how long a brake operation is applied, it is possible to reduce a deviation between a pressing force instruction value and a generated pressing force by updating the characteristic of the relation between a pressing force instruction value and rotational position each time an estimated thrust force value is calculated during one brake operation. It is possible to steadily keep followability to a pressing force instruction according to an actual state of the rigidity characteristic of the electric caliper, thereby ensuring generation of an appropriate brake force.

    摘要： An electric booster according to the present invention comprises a booster piston disposed around an input piston so as to movable relative to the input piston. The booster piston and input piston also serve as a primacy piston of a tandem master cylinder. A brake fluid pressure is generated in the tandem master cylinder by an input thrust force provided from a brake pedal to the input piston and a booster thrust force provided from the electronic actuator to the booster piston. In this electric booster, a slide hole is formed through the secondary piston of the tamed master cylinder in the axial direction therefore, and a rod member is slidably disposed through the slide hole. When the fluid pressure is not increased in the primary pressure chamber, due to the fluid pressure in the secondary pressure chamber, the rod member comes to abut against the input piston, and a reactive force in the secondary pressure chamber is returned to the brake pedal.
