    • A dielectric filter comprises a pair of dielectric resonators 11 and 12, which have outer conductors 11c and 12c formed with cutouts 11k and 12k, respectively. Interstage coupling electrodes 11f and 12f are provided within the region of these cutouts 11k and 12k, so that the electrodes 11f and 12f do not contact with the conductors, such as outer conductors 11c, 12c and the inner conductors 11d, 12d. The dielectric resonators are connected in such a manner that these electrodes 11f and 12f are brought into contact with each other. Furthermore, input/output coupling electrodes 11g and 12g are provided within the region of the cutouts 11k and 12k. Then, by connecting the electrodes 11f and 12f, it becomes possible to provide a dielectric filter which is compact in size and capable of reducing the number of parts and, therefore, cheap in cost.
    • 介质滤波器包括一对介质谐振器11和12,它们分别具有形成有切口11k和12k的外导体11c和12c。 级间耦合电极11f和12f设置在这些切口11k和12k的区域内,使得电极11f和12f不与外导体11c,12c和内导体11d,12d等导体接触。 介质谐振器以使得这些电极11f和12f彼此接触的方式连接。 此外,输入/输出耦合电极11g和12g设置在切口11k和12k的区域内。 然后,通过连接电极11f和12f,可以提供尺寸紧凑并且能够减少部件数量并因此成本低廉的介质滤波器。

    • A filter device for a transmitter-receiver antenna includes a transmission side filter having resonators and a reception side filter having resonators. Each of the transmission side resonators has a first characteristic impedance ratio other than one. On the other hand, each of the reception side resonators has a second characteristic impedance ratio being set to a value which prevents spurious resonance of the reception side filter at an integral multiple of a fundamental resonance frequency of the transmission side filter, so as to avoid the situation where spurious components increase at the above-noted integral multiple in a frequency characteristic of the transmission side filter being affected by a frequency characteristic of the reception side filter.
    • 用于发射机 - 接收机天线的滤波器装置包括具有谐振器的发射侧滤波器和具有谐振器的接收侧滤波器。 每个发送侧谐振器具有除了一个之外的第一特性阻抗比。 另一方面,每个接收侧谐振器的第二特性阻抗比被设定为防止接收侧滤波器的杂散谐振为发送侧滤波器的基本共振频率的整数倍的值,以避免 发送侧滤波器的频率特性中的杂散分量以上述积分倍数增加的情况受到接收侧滤波器的频率特性的影响。

    • The variable valve timing mechanism includes a housing, a rotor rotatably supported within the housing, and a lock pin. The housing includes a plurality of fluid chambers one of which includes a lock bore. The rotor includes a central portion and a plurality of vanes extending radially from the central portion. Each of the vanes extends into the fluid chambers of the housing to define an advanced fluid chamber and a retarded fluid chamber. One of the plurality of vanes includes a pin bore. The lock pin includes a shank section and an insertion section. The insertion section includes a nonlinear outer side profile. The lock pin is slidably received within the pin bore between an unlocked position and a locked position in which the insertion section of the lock pin is received within the lock bore of the housing thereby prohibiting relative rotation between the housing and the rotor.
