  • Patent number: 5366922
    Abstract: The method of producing a CMOS transistor device. A pair of device regions are formed in separated relation from each other by a field oxide film on a pair of corresponding well regions formed in a semiconductor substrate. A gate insulating film and a gate electrode is sequentially formed on each of the device regions. The gate insulating film is removed through a mask of the patterned gate electrode to expose a silicon active surface at least in one of the device regions. A diborane gas containing P type impurity of boron is applied to the silicon active surface to form thereon a boron absorption film. N type impurity of arsenic is doped into the other device region by ion implantation to form N type of source and drain regions while masking the one device region. The boron is diffused from the adsorption film into the one device region to form P type of source and drain regions by annealing of the substrate.

  • Patent number: 5274462
    Abstract: A image input/output method for reading fine input data without increasing the amount of information and for reproducing fine image data from the input data. Data is extracted from every nth pixel in a line of pixels. The extraction process is repeated for n lines of pixels while sequentially changing the phase of the pixels from which data is extracted for each of the n lines. A single data line is formed by combining the pixel data extracted from the n lines of pixels.

  • Patent number: 5239603
    Abstract: An integrally-molded ceramic cylindrical alignment sleeve is composed of a cylindrical sleeve body and at least three convex portions located on the inner surface of the sleeve body, each of the convex portions extending from one end to the other in the longitudinal direction of the sleeve body, with the upper surface of each of the convex portions being formed in the shape of a reverse arc and the section where each of the convex portions connects to the inner surface of the sleeve body being in the shape of a continuous R. A method of producing this integrally-molded ceramic cylindrical alignment sleeve is disclosed.

  • Patent number: 4880175
    Abstract: In an automatic winder, the tension device provided on each winding unit has a tenser in contact with a yarn to apply a resistance thereto, and a driving actuator of said tenser member, and each of the actuators provided on each winding unit is associated with a control device positioned separately from each winding unit, and adjustment of the tenser member is remote-controlled. The control device is used to vary the yarn tension in accordance with amount of yarn layer on a package, winding speed of a yarn and the like.
