  • Patent number: 5082747
    Abstract: A magnetic thin film recording disk includes a substrate of a hard electroless plated nickel surface that has been textured to encourage a circular anisotropic orientation of crystal growth during a pass-by sputtering in a continuous production line. A thin film chromium nucleating layer that is substantially free of any oxidation that would affect the recording properties is subsequently deposited, and then a thin film magnetic layer of a cobalt alloy, having a desired circular anisotropic crystal growth, is deposited through the sputtering process. The resulting magnetic thin film recording disk is then coated with a thin film of a carbon protective material.

  • Patent number: 5048332
    Abstract: A part of a tube, through which a fluid passes, is cooled by means of an electronic cooling element and a flow rate of the fluid is measured on the basis of a temperature of a surface of the tube cooled. Not only can the flow rate of the liquid flowing through the tube be determined in a noncontacting manner and a very small flow rate of the liquid be determined, but also the tube is cooled so that no bubbles are generated, and thus the measurement of the liquid, which is apt to generate gases, such as low boiling point liquid, is possible. In addition, the measurement is not influenced by the gases dissolved in the liquid and merely the temperature difference resulting from the flow of the fluid, that is, the rise of the temperature of the fluid, is detected to prevent the measurement from being influenced by the installing posture of the flow meter, so that a highly accurate measurement is possible. Consequently, stable and sure controlling flow rate of liquid is possible.

  • Patent number: 5049933
    Abstract: An image edit input device is disclosed which feeds data concerning an edit area of an original document to a copying machine. This image edit input device is provided with a tablet possessed of a surface conforming in size with an original document. On this tablet are inscribed marks for effecting the input of special data such as ratio of copying magnification, number of copies to be produced, and size of copying paper. By the depression of the tablet, therefore, special modes and copy data such as the number of copies to be produced can be injected as an input other than the coordinates data of the edit area can be fed in. When the tablet is depressed, the question as to whether this depression is for feeding the coordinates data or the data other than the coordinates data is decided by the manipulation of switches.

  • Patent number: 5047800
    Abstract: An image recording apparatus for recording an image on a record sheet by projecting the image onto an image recorder through a projection lens includes an image position detecting device for detecting position of the image to be projected on the image recorder and a reflecting mirror for correction of the image position for shifting an optical axis of light incident on the image recorder in the direction orthogonal to the direction of feeding a recording material. A shift of the reflecting mirror for correction of the image position and a time to feed the recording material to the image recorder are controlled in response to the result of detection by the image position detecting device. This makes it possible to control a position where the image is to be formed in both the recording material feeding direction and the orthogonal direction thereto.

  • Patent number: 5042940
    Abstract: An optical measuring apparatus for examining an eye which automatically aligns the optical axes of said apparatus and the eye with each other and focusing the light emitted by said apparatus on the eye. When these operations are accomplished, the projection of a measuring light is automatically started. The apparatus includes axes-aligning-focusing optical system. The optical system has a pair of optical axes-aligning light sources. Two images of beams emitted by the respective optical axes-aligning light sources and reflected by the cornea of the eye are detected by a light receiving sensor when the beams are focused substantially on the eye. Discriminating devices discriminate whether or not the optical axes of the two cornea-reflected images detected by the light receiving sensor align with the optical axis of the eye in Y-direction of the light receiving sensor.
