    摘要: A slide glass with a sample rested thereon is placed on an interior total reflection prism with a matching oil between them. A laser beam is applied through a prism to the sample, and evanescent light is generated on the sample surface. Above the sample, a probe supported at a free end of a cantilever is located, and an objective is provided above the probe. The objective has an angular aperture exceeding a vertical angle of the probe, where the angular aperture indicates an angle from a focal point of the objective to a diameter of entrance pupil. A scattering light detection lens barrel is provided above the objective, and cooperates with the objective to constitute a scattering light detection optical system. The optical system detects scattering light generated when the probe is introduced to the evanescent light.

    摘要: A hole is formed in a silicon substrate, passing through the substrate. An insulating film is formed on one face of the silicon substrate and one open end of the hole is thus closed by the insulating film. An antireflection film is attached to that area of the insulating film by which the one open end of the hole is closed. An optical fiber is fitted and fixed in the hole. An optically-transparent conical probe is formed on the area of the insulating film which corresponds to the hole in the silicon substrate and the probe is coated by a metal film while leaving a tip of the probe not coated. A fine aperture is thus formed at the tip of the probe to allow light to enter into the probe through the fine aperture. The metal film prevents light reflected from entering into the probe and light from being leaked from the probe, and it is connected to an electrode to use tunnel current to position the fine aperture near a sample.

    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.

    摘要: In an electrophotographic photosensitive device including a conductive layer, a selenium based photoconductive layer and a transparent insulating layer which are sequentially laminated, the conductive layer is formed of an aluminum substrate conductive layer, a zinc conductive layer a copper conductive layer, and silver conductive layer which are sequentially laminated to each other. As a result of this structure, the charge injection characteristic of the photosensitive device during primary charging is improved, and the charge injection preventing characteristic during the simultaneous secondary charging and image exposure steps is sufficiently maintained. The conductive layers contact each other intimately. The electrophotographic photosensitive device is highly humidity durable and exhibits a long life and can obtain high electrostatic contrast.

    摘要: A photosensitive member for electrophotography basically comprises a conductive support, on the surface of which a photoconductive layer and a transparent insulating layer are sequentially laminated. The photosensitive member is adapted to be used in a process for forming an electrostatic latent image including sequential steps of a primary corona charging concurrent with imagewise exposure, a secondary corona charging and a flush irradiation. The surface of the conductive support is treated to a mirror finish, based on experimental finding that the contrast voltage of the latent image depends on the degree of surface roughness of the support.
