  • Patent number: 6417973
    Abstract: The object of the invention is to reduce the thickness of electronic image pickup equipment as much as possible, using a zooming mode having stable, high image-formation capabilities from an object at infinity to a near-by object. The electronic image pickup equipment comprises a zoom lens system comprising a negative, first lens group G1, a positive, second lens group G2 and a positive, third lens group G3. For zooming from the wide-angle end to the telephoto end of the zoom lens system upon focused on an object at infinity, the separation between G2 and G3 becomes wise. By moving G3 toward the object side of the system, the system can be focused on a nearer-by object. In the zoom lens system, the second lens group G2 comprises one positive lens 2a, one negative lens 2b and a lens subgroup 2c comprising at least one lens, and the third lens group G3 comprises one positive lens.

  • Publication number: 20020073919
    Abstract: By using a semiconductor single crystal pulling apparatus for growing single crystals by the Czochralski method while rotating the melt by a magnetic field and electric current, namely by the EMCZ method, which comprises a main pulling means for pulling a single crystal, a holding mechanism for gripping an engaging stepped portion formed on the single crystal through engaging members and a sub pulling means for moving the holding mechanism up and down and in which an electric current is passed through the main pulling means and through the sub pulling means, it is possible to prevent heavy single crystals from undergoing a falling accident and, at the same time, effectively reduce the power consumption. In this pulling apparatus, it is effective to feed an electric current to the sub pulling means alone and it is desirable to dispose two or more electrodes whether the pulling means is of a shaft type or wire type.

  • Publication number: 20010047749
    Abstract: An apparatus for growing a single crystal of semiconductor is provided, which makes it possible to grown a heavy single crystal of semiconductor of 100 kg or greater in weight even if a growing single crystal contains the neck. In the apparatus, the first and second electrodes are provided in such a way that the first ends of the first and second electrodes are electrically connected to the power supply and the second ends of the first and second electrodes are contacted with the melt in the crucible. During the growth process, a specific voltage is applied across the first ends of the first and second electrodes, thereby forming the electrical current path interconnecting the second ends of the first and second electrodes in the melt. The magnetic field is generated with the magnetic field generator to intersect with the electrical current path in the melt. No electric current flows through the growing single crystal from the melt.

  • Patent number: 6327536
    Abstract: A vehicle environment monitoring system for an automotive vehicle is capable of accurately detecting the movement of an object existing in an environment of the vehicle, and determining the possibility of collision between the object and the vehicle, thereby appropriately warning the driver. A relative position of the object to the automotive vehicle is detected from the image obtained by a camera mounted on the vehicle to obtain position data. Positions of the object in a real space are calculated based on a plurality of time series items of the position data detected on the object, and a movement vector of the object is calculated based on the positions in the real space. It is determined based on the movement vector whether or not the object has a high possibility of collision against the automotive vehicle.

  • Patent number: 6325848
    Abstract: A single-crystal silicon substrate is provided, which makes it possible to accurately control the concentration and profile of an introduced impurity. This silicon substrate is comprised of a single-crystal Si base layer and a single-crystal Si low oxygen-concentration layer formed on the base layer. The base layer has a first oxygen concentration and the low oxygen-concentration layer has a second oxygen concentration lower than the first oxygen concentration. This silicon substrate is fabricated by (a) growing a single-crystal Si epitaxial layer on the main surface of a single-crystal Si base material in such a way that the epitaxial layer has a second oxygen concentration lower than of the first oxygen concentration, or (b) heat-treating a single-crystal Si base material to cause outward diffusion of oxygen existing in the base material through the main surface thereof, thereby forming a low oxygen-concentration layer extending along the main surface of the base material in the base material.

  • Publication number: 20010002936
    Abstract: An image recognition system recognizes correspondence between object images contained respectively in two images obtained by two infrared ray cameras. One of the two images is set to a reference image and another of the two images to a comparison image. A correlation parameter indicative of a correlation between a reference pattern contained in the reference image and containing an object image and each pattern contained in the comparison image and identical in shape to the reference pattern is calculated by using a luminance value indicative of a luminance of the reference pattern and a luminance value indicative of a luminance of the each pattern contained in the comparison image. Based on the calculated correlation parameter, a pattern having a highest correlation with the reference pattern is extracted from the comparison image as a corresponding pattern which corresponds to the reference pattern.

  • Patent number: 6077346
    Abstract: In the growth of a semiconductor single crystal according to the Czochralski method, a magnetic field is generated in a semiconductor melt and a current is supplied in the semiconductor melt in a direction perpendicular to the magnetic field. This makes it possible to cause the semiconductor melt to rotate spontaneously without rotating the crucible, thereby to grow a single crystal of semiconductor without striation even when growing a single crystal of semiconductor having a large diameter. Also it is made possible to exactly control the rotation rate of the semiconductor melt by changing the intensity of the magnetic field and the magnitude of the current independently. Further, the distribution of the rotation rates in the semiconductor melt can also be varied by changing the position of electrodes or electrode protecting tubes for immersing in the semiconductor melt.
