    摘要: A dielectric duplexer includes a substantially-rectangular-parallelepiped-shaped dielectric block. The interior of the dielectric block includes inner-conductor-formed holes containing inner conductors. An outer conductor is formed on the substantial entirety of an exterior surface of the dielectric block. Input/output electrodes and antenna input/output electrodes are formed at predetermined positions. Thus, the dielectric block is provided with a band eliminate filter and a band pass filter. A C-L-C &pgr;/2 phase circuit in which C, L, and C are arranged in the shape of the letter &pgr; is provided between an antenna and the antenna input/output electrode of the band eliminate filter, and the antenna is connected to the antenna input/output electrode of the band pass filter.

    摘要: A display has a display panel of a first aspect ratio and is able to display on the display panel an image of a second aspect ratio whose width element is larger than that of the first aspect ratio. The display has a gate driver, a data driver, and a timing controller. The gate driver sequentially selects gate lines of the display panel. The data driver stores data for one gate line and supplies the data to one of the gate lines selected by the gate driver. The timing controller supplies control signals to the gate and data drivers so that predetermined data is displayed in top and bottom non-image areas of the display panel during a vertical blanking period. The display is capable of displaying images of different sizes.

    摘要: A scanning tunneling microscope has an STM unit including a probe for scanning the surface of an object. The STM unit has at its outer peripheral surface a cylindrical enclosing member extending towards an object table. When the object is observed, the object table is elevated or the STM unit is lowered, so that the enclosing member is urged upon the table. The table and the STM unit constitute one body. As a result, relative movement between the object and the probe can be prevented, and also influence due to vibration can be prevented. In addition, the enclosing member isolates the object and the probe from the outside space, whereby electric noise, magnetic noise, sound noise and air flow are shielded. Thus, the influence due to external vibration can be reduced, and the stability is enhanced.

    摘要: A probe for scanning a sample is attached to a probe electrode supported by a cylindrical piezoelectric actuator. The actuator has four drive electrodes on its periphery, and deforms in the three axial directions in accordance with the voltage applied to the drive electrodes. A girdling electrode is provided between the actuator and the probe electrode. The girdling electrode is insulated from the probe electrode and the drive electrodes by insulator members provided on its upper and lower surfaces. A bias voltage signal S1 is input to an operational amplifier of which the output is connected to the girdling electrode. The amplifier is a voltage follower for equalizing the potential of the girdling electrode to that of the bias voltage signal S1. An operational amplifier has a non-inversion input to which the bias voltage signal S1 is input, and an inversion input connected to the probe electrode. While equalizing the potential of the probe electrode to that of the bias input voltage S1, the amplifier converts a tunnel current flowing between the probe and the sample to a voltage signal S2. An operational amplifier subtracts a bias voltage component from the voltage signal S2, and outputs a tunnel current signal S3.
