Title: Screw propulsion device with current fairing mechanism for outboard and onboard engines
Inventor: HATANAKA MITSUYOSHI
IPC: B63H5/16
Filed: 1992-05-27
Abstract: PURPOSE:To generate large water flow energy for a remarkable increase in propulsion force, and restrain the roll and pitch of a hull due to turbulent flow state by turning the turbulent and diffused state of a water flow due to a rotating propeller blade into laminar and centralized state with a current fairing plate. CONSTITUTION:When this device is applied to an outboard engine, a current fairing device 30 is provided immediately near a position in rear of the propeller blades 17 of a screw propulsion section 3 under the outboard engine. This current fairing device 30 is constituted of a longitudinal current fairing plate 31 and a transverse current fairing plate 32 assembled like parallel crosses. The current fairing plates 31 and 32 are respectively of rectangular flat type, and formed to be as thin as possible within a range not providing resistance against a water flow. Also, the plates 31 and 32 are laid along plane orthogonal with propeller blade surface within a range not substantially exceeding the diameter of the propeller blades 17, thereby enabling the plates 31 and 32 to internally form closed divisional space K. According to this construction, turbulent flows are received with the plates 31 and 32 for rectification, thereby paralleling water flow directions.

IPC: B22D11/06
Filed: 1979-12-14
Abstract: PURPOSE:To continuously cast a thin-walled metal strip of uniform thickness at high speeds by running a metal belt in an arc shape as a mold, pouring molten metal to the inside surface side of the arc and solidifying the same under centrifugal force on the inside surface of the belt. CONSTITUTION:Two sheets parallel dics 1 are rotatively driven by a shaft 2, and a steel belt 3 is pressed to the outside circumference of the two discs 1 by way of pulleys 4. Cooling water is injected under high pressure between the belt 3 and a water cooling plate 5, whereby the belt 3 is cooled from the back. On the other hand, the molten metal in a tundish 6 is flowed out upward through a nozzle 7, and is conveyed by rotation in contact with the belt 3; in addition, it is pressed by centrifugal force to the belt 3 to uniform thickness. The molten metal is allowed to solidify thoroughly before it reaches an outlet 8. At this time, the discs 1 play the role of the side walls of the mold, thereby determining the width of the strip 9. Additionally, the strip 9 is unbent by a guide 10 at the outlet, is taken out to the outside in a linear shape and is coiled by a pulley 11.

Abstract: PURPOSE:To prevent the oscillation of electrostatic charge wires when a high voltage is impressed to the charge wires and to prevent the leak discharge between an electrostatic charger case and the charge wires by providing charge wire holding members which extend both ends of the charge wires and charge wire supporting members in light sliding contact with the charge wires. CONSTITUTION:The charge wire holding members 3a, 3b which extend both ends of the charge wires 1a, 1b and the charge wire supporting members 6a, 6b in light sliding contact with the charge wires 1a, 1b are provided. The charge wires 1a, 1b begin to oscillate vertically and laterally in the central part thereof when the high voltage is impressed to the wires 1a, 1b, but the wires 1a, 1b move slidingly on the surfaces of the charge wire supporting members 6a, 6b disposed near both ends of the wires 1a, 1b and, therefore, this sliding movement turns to friction resistance and the oscillation energy is absorbed. The shortening of the distance between the charge wires and the charger case is thereby obviated and the leak discharge is prevented.

Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To form an optical diffraction grating, a waveguide, and other active devices on the same plane, by depositing a continuous material layer on a substrate which material constitutes a waveguide whose thickness and width in the direction of a part of the longitudinal axis change periodically. SOLUTION: A buried hetero-structure waveguide 2 contains a substrate 21, on which a buffer layer 24 is formed. A multi-quantum well(MQW) stack 6 serving as a waveguide core is formed on the buffer layer 24. That is, a mask of suitable structure is selectively deposited on the buffer layer 24, and the MQW stack 26 is so formed that an optical diffraction grating 27 is contained. In this mask, a pair of strips exist and the width changes periodically. The change of the width of a gap 41 reflects the change of the widths of the strips. The widths of the mask 40 and two strips forming its gap are large enough for the MQW material growing the gap to form the waveguide.
